OCTOBER 6, 1904. The 1 89th regular meeting was held at the residence of Dr. Wm. H. Ashmead, 1807 Belmont avenue, N. W., Vice-Presi- dent Hopkins in the chair, and Messrs. Ashmead, Barber, Currie, Doolittle, Dyar, Gill, Hay, Heidemann, Morris, Patten, Schwarz, Stiles, Ulke, and Webster, members, and Messrs. Phillips, Strauss, and Charles B. Dyar, visitors, present. Dr. Gill, as a delegate from the Society to the International Geographic Congress held in Washington the month previous, made a brief report. Mr. Schwarz exhibited a pamphlet published in Havana, Cuba, by the " Institute de Segunda Ensenanza" and entitled: "Catalogo Numericodel Museo Zoologico Cubano (Museo Gund- lach). Habana, Cuba, 1895." The pamphlet comprises 112 pages and is manifestly intended to serve as a guide to Gund- lach's "Fauna Cubana" as illustrated by the specimens in the Gundlach collection now preserved at the "Institute." At any rate the pamphlet seems to be entirely unknown to zoologists. While at Havana, Mr. Schwarz ascertained that this "Catalogo " is an exact reproduction of Dr. Gundlach's manuscript field- book, in which Gundlach entered each species found by him in Cuba, from mammals down to insects, without any systematic order; except that for each Order a separate set of numbers 2 ENTOMOLOGICAL SOCIETY was used. As matters stand, this pamphlet is of little scientific value (except for specific localities mentioned by Gundlach), since the families, genera and species are listed without any systematic arrangement. If a little circumspection had been used in editing the pamphlet for publication it would have been an excellent check-list of the animals found in Cuba by Gund- lach. As to the insects, the Orders Diptera and Coleoptera are not included in the pamphlet, and Mr. Schwarz was in- formed by the authorities of the " Institute" that there were no funds to continue and complete the publication of the "Cata- logo." The date on the title page of this pamphlet is mislead- ing, as are also the dates on the other works on the Cuban fauna by Dr. Gundlach, published in Havana" by the Academy of Sciences or otherwise, the title pages, with the date, being al- ways printed as page i , while the publication of the body of the volumes extended over several subsequent years. Mr. Barber stated that a collection of land shells from Nas- sau, Bahama Islands, received a few days ago by the Division of Molluscs in the National Museum, was found to be swarming with a small dipteron. The matter was called to his attention, and upon visiting the collection he recognized the flies, by their erratic, jerking movements, as belonging to the family Phoridge. The snails were dead, but not wholly dried up, and there was considerable odor about them. He noticed that although some of the flies flew readily (the cTc?), others (the ? 9 ) were wing- less. He collected a number of both forms in different stages, and these were determined by Mr. Coquillett as belonging to Puliciphora occidentalis Melander and Brues, originally de- scribed, about a year ago, under the genus Stethopathus, from three $ specimens collected at Wood's Hole, Mass., at a place where burrows of Halictus were abundant. It was then in- ferred that the flies had some symbiotic relation with these bees. A winged cT was taken at the same time by the authors just mentioned, but was thought to belong to some other spe- cies on account of differences in the head. Mr. Coquillett told Mr. Barber that the head in the cT cT collected on the snails dif- fered considerably from that of the $ $ , and he believed that the specimen obtained by Brues and Melander was the true cT OF WASHINGTON. 3 of this species. Mr. Barber stated that there are some differ- ences between Melander and Brues' figure of the $ and his own specimens in the length of the joints of the front and hind tarsi, the most striking difference being in the basal joint of the hind tarsus, which, in his specimens, is very broad and has a beauti- ful set of diagonal rows of bristles, similar to that found on the same joint in beetles belonging to the genus Mordellistena. Mr. Barber thought it improbable that a wingless $ could have had a chance to oviposit in the collection since the introduction of the latter into this country, and he believed that the flies should be labeled as coming from the Bahamas. Microscopic and pinned specimens of adults, c? and $ , and larvae and pupae were shown, as also Melander and Brues' published figure. Discussing this note Mr. Currie mentioned having found Phorid flies in a cigar box of insects sent to the National Mu- seum from the Hawaiian Islands by Dr. Ashmead during the summer of 1901. They had bred from several large dragon- flies of the genus Anax, eggs of the Phorid having undoubtedly been deposited on them shortly after they were collected and before they were packed for shipment. Dr. Stiles entertained the Society with a short account of the work done at the International Zoological Congress which met at Bern, Switzerland, the past summer. He stated that there were 400 members present, 26 of whom were Americans. Unfortunately he was unable to attend any -of the meetings de- voted to entomology, since his position on the committee on rules of nomenclature kept him closely engaged for 18 days. He mentioned in brief the work of that committee and stated that the code as revised and adopted is now in type and will be published in English, French, and German. Dr. Ashmead, under the title "New Hymenoptera from the Philippine Islands," reviewed the work that has been done upon Philippine Hymenoptera and mentioned the sources of material from that region which has come into the possession of the National Museum. He also exhibited a box containing some of the more interesting species from recent sendings and made comments upon them. He called special attention to a specimen of the hitherto undescribed 9 of the ant Sim a allo- ENTOMOLOGICAL SOCIKT Y borans Walker. In conclusion, he stated that there are now about 240 species of Philippine Hymenoptera in the collection of the National Museum probably not over three per cent of the species which will eventually be found in those islands. Referring to the subject brought up by Dr. Ashmead of spe- cies of ants known only from one sex, Mr. Schwarz stated that in Cuba the winged forms of some species of ants are brought out in enormous numbers by the summer rains. Yet he has never, even after repeated attempts, been able to find the winged forms of Dorymyrmex pyramicus Roger, the ' ' Lion ant' ' of the Cubans, which in that country plays the role of the Guate- malan kelep (Ectatomma tuber culatum Olivier) by protecting solitary cotton trees from the boll weevil (Anthonomus gran- dis) . He had not found it possible to dig down to the real nest of Dorymyrmex. Mr. Barber stated that only in one instance had he seen $ $ of the common Texas harvesting ant (Pogono- myrmex barbatus}. This occurred last summer on the stage road between Brownsville and Alice. The ground for an area of about 30 feet was densely covered with cT & and $ $ scramb- ling over one another. The sight was a novel one, and attracted the attention of everyone on the stage. Dr. Dyar read a paper, by Mr. Currie and himself, entitled "The Egg and Young Larva of Culex perturbans Walker," 1 after which, in discussing the possible habitat of the larva, Dr. Dyar mentioned a suggestion made to him by Dr. Howard, which seemed plausible, viz., that the larva may be found to live in bodies of stagnant water thickly covered with algae situations which have heretofore been considered unfitted for mosquito larvae and that its curiously constructed air tube may serve to penetrate the mass of vegetation, thus enabling it to secure air from the surface. He had not yet had an oppor- tunity of testing the theory. Dr. Hopkins stated that during the past summer he had dis- covered a number of mosquito eggs belonging to the genus Megarhinus on the surface of water in a rain barrel at Kanawha Station, West Virginia. Only one of the eggs hatched. The 'Published in Proc. Ent. Soc. Wash., vi, No. 4, pp. 218-220, i fig.; author's extras published November 4, 1904. OF WASHINGTON. f) larva issuing from it was furnished with a live Culex larva about twice its size. The Megarhinus seized the Culex by the anal segment and gradually devoured it. It was then furnished with a Culex larva of still larger size and it found, upon grasping this larva as it did the first one, that it could not maintain its hold, but was shaken off. The Megarhinus thereupon changed its tactics and grasped the Culex by the prothoracic segment. This ruse was successful, for the Culex was then unable to free itself from the Megarhinus and was relentlessly devoured. All larvae subsequently attacked by Megarhinus were seized by the pro- thorax regardless of their size. Dr. Hopkins stated that this was the only time he had found Megarhinus in West Virginia. Mr. Schwarz said he believed it would be well to explore for mosquito larvae pools whose water was covered with the irides- cent film of oxide of iron. He thought it quite possible that interesting and peculiar larvae might be found inhabiting such situations. He mentioned the location of a spring pool of this character near Plummer's Island, Maryland. Dr. Hopkins stated that he had found larvae in film-covered pools in the neighborhood of coal mines. Dr. Dyar remarked that these were in all probability the larvae of Culex pipiens. Dr. Hop- kins questioned Mr. Barber as to whether Megarhinus adults were known to bite, Mr. Barber replying that he thought in- stances of their biting were known. Mr. Schwarz exhibited a box of the ears of the grass Cen- chrus echinatus Linn., collected by him at Cayamas, Cuba, in May, 1904, with numerous specimens of large-sized insects cap- tured by the spinous spicules of the grass. He has prepared the following abstract of his remarks : THE INSECT-CATCHING GRASS OF CUBA. BY E. A. SCHWARZ. [Author's Abstract.} Cenchrus echinatus Linn, is a widely distributed grass in trop- ical countries, both in the Old and New Worlds, but its insect- capturing capacity seems to have hitherto escaped the attention of botanists and entomologists alike. In the sugar-cane grow- ing regions of central Cuba it occurs plentifully along the road- 6 ENTOMOLOGICAL SOCIETY sides between the sugar-cane fields, and at the commencement of the rainy season (end of April and first part of May), which is also the season of the swarming of a great number of insects, the ears of the grass are loaded with a multitude of large insects, mostly Coleoptera, captured by the spiny involucre of the spike- lets of the grass. It is evident that the insects are captured while flying against the minutely barbed spines, and that almost always they are held fast by the hind wings, very rarely by some other part of the body. Among the numerous species found on the ears of the grass are some of the most powerful Coleoptera of Cuba, for instance, the well-known "Cucujos" (genus Pyro- phorus) and the "Gallegos" (night-flying Scarabaeid genera L/achnosterna, Cyclocephala, etc.), but none of them are ever able to free themselves from the death grip of the grass. The follow- ing list includes only those species which could be picked off the ears of the grass in thousands of specimens within half an hour's walk. Night-flying species : Pyrophorus noctilucus,P. hauanien- sis, Monocrepidius bifoveatus, M. iimdus? Glyphonyx fusculus, Lachnopus curmpes? 2 , Lachnosterna crenaticollis, L. patruelis, L. suturalis, L. dissimilis, Cyclocephala signata. The day-flying Coleoptera are : Cycloneda sanguinea, Thonalmus, two or three species, Exophthalmus scalaris, Anoplosiagon pallidum. 3 The Hymenoptera are represented by numerous specimens of Apis mellifera; the Diptera by Mallophora orcina (?), and the Neu- ropteroid insects by several species of Odonata. For reasons which I cannot explain, the L/epidoptera, Hemiptera, and Or- thoptera were not represented among the insects thus captured. Very small insects, such as ants and small beetles of various families are able to walk with impunity over the barbs of the grass; and there are two large-sized species, viz., the grass- seed feeding earwig, Apterygida linearis, and a grass-seed suck- ing Pentatomid bug, (Ebalus pugnax both excessively com- mon in Cuba during the rainy season which are able to brave the dangers of the grass. The rather extensive subject of insects caught by plants may be divided into the following topics : 1 This and the preceding species as well as various other large-sized Elateridae that are attracted by light are popularly called in Cuba "Cucujos ciegos, " blind Cucujos, because they lack the luminous, eye-like thoracic spots. 2 1 experience some difficulty in the specific determination of this species. It is by far the most abundant, the most voracious and most polyphagous Otiorhynchid beetle in central Cuba. It is active both at day and night. 3 This little Scarabaeid beetle flies about in countless numbers for an hour or so after sunrise, and in much smaller number just at sunset. OF WASHINGTON. PLATE I. THE INSECT-CATCHING GRASS OF CUBA. ENTOMOLOGICAL SOCIETY A. Insectivorous plants, as exemplified by Sarracenia, Dar- lingtonia, Drosera, Nepenthes, Utricularia, and (Enothera spe- ciosa. This phase of the subject has often been presented in print, both in the scientific and popular literature. B. Insect- catching, but not insect- devouring, plants, the plants deriving no conceivable benefit from the capture of the insects. There are innumerable instances of this sort and the phenom- enon is so common that, generally speaking, no particular at- tention has been given to it by entomologists, excepting in one case, viz., the insects preserved in amber or gum anime, con- cerning which quite an extensive literature has arisen. This whole phase. of plants catching insects in an accidental or ap- parently accidental way may again be subdivided as follows : 1 . Plants capture insects by means of sticky surfaces or exuda- tions, which may occur on the stems, leaves, flowers, or any other part of the plant. In many instances these exudations have ap- parently no attraction to insects. In other instances sticky or gummy substances, exuding from wounds or other injury re- ceived by plants, attract and capture insects by the odor of the excretion as exemplified by the resin of our coniferous trees. Finally, such exudations, when fermenting, possess intoxicating properties and attract and drown many, often large-sized, in- sects. Of this character are the exuding saps of oaks, birches, sugar maples, and other trees. 2. Sharp blades of grasses capture insects. This is a rare phe- nomenon, but is referred to both in the European and North American literature. Diurnal or crepuscular insects, mostly Coleoptera, while slowly flying about get caught by the grass in such way that the blade enters the angle formed by the bases of the fore and hind wings. The insects caught in this particular position are entirely unable to free themselves, and perish. 3. Insects are caught by the hairy surfaces of plants. This is also a common occurrence of a purely mechanical and accidental nature. Small and weak insects, usually Diptera, fly against the hairy stem or leaves of plants, e. g., our common mullein, and, are unable to extricate themselves from the dense mass of hairs. 4. Crepuscular or Nocturnal Lepidoptera caught by the tongue by the flowers of Physianthus albens and other asclepiadacious plants. 5. Insects are caught by spinous plants, for instance, thistles and cacti. These do not capture any insects except that in very rare instances a specimen gets impaled by flying against the spines. There is in Cuba a second species of Cenchrus just as spinous as Cenchrus echinatus, but the spines point upwards so that insects which happen to fly against the ears of the grass OF WASHINGTON. 9 can easily free themselves. In the case of Cenchrus echinatus, however, the spines or barbs along the involucres of the ripen- ing seeds point downwards and form a perfect and infallible trap for any insect that flies against the ears of the grass. In spite of the fact that even in a very small area untold thousands of insects are thus captured every night or day by this Cenchrus echinatus, there appears to be no'ground for be- lieving that the plant derives any benefit from their capture, and the phenomenon must be classed among the numerous in- stances of plants accidentally capturing and killing insects. 1 In discussion, Mr. Morris observed that an allied species of grass, Cenchrus tribuloides, the common sand burr, had been found by him along the shores of Lake Michigan in"northwestern Indiana and northeastern Illinois with certain species of flies caught in its spines. Mr. Schwarz said that Elaterid beetles caught by the grass live for three or four days andTthen decay. He had never seen any insects caught by the sand burr in Florida. The subject of insects impaled on thorns was then brought up, Mr. Schwarz maintaining that such cases are the work of shrikes and do not result from accident. Mr. Hay stated that he had found insects in central Indiana mostly grasshoppers impaled upon the barbs of barbed wire fences, and this in a region where shrikes are quite rare. NOVEMBERS, 1904. The i9oth regular meeting was held at the residence of Dr. H. G. Dyar, 1512 Twenty-first street N.W. Vice- President Banks presided, and there were present Messrs. Barber, Benton, Currie, Doolittle, Dyar, Gill, Hay, Heidemann, Hopkins, Mor- ris, Patten, Piper, Ulke, and Webb, members, and Messrs. Charles B. Dyar and H. J. Nichols, visitors. Mr. Barber exhibited c? and 9 specimens and larval skins of a rare Dermestid beetle, and furnished the following abstract of his remarks : 1 The preservation'of the insects caught by the grass proved to be a diffi- cult matter, and some of the finest examples of ears, notably one that had captured three specimens of Pyropkorus noctilucus, were lost, partly by the decay of the specimens and partly by the attacks of house ants. Those I brought to Washington were pinned in a box which was kindly photographed by Prof. A. A. Doolittle. 10 ENTOMOLOGICAL SOCIETY NOTE ON THAUMATOGLOSSA (AXINOCERUS) AMERICANA JAYNE. BY HERBERT S. BARBER. [Author's Abstract.] On April 24, 1904, I found on the bark of a hackberry tree, at Victoria, Texas, a mass of Mantid eggs about which were numer- ous specimens of a Chalcid (Podagrion mantis Ashm.), and thinking that I might breed other parasites, I took a chip of the bark with the mass on it and put it in a tin box. On looking at it a few days later I noticed several Dermestid larvae which in- terested me, but as there was much else in the strange country around Brownsville to interest me I did not pay much attention to them. On June loth the adults were alive, and on the 2oth they were dead. Mr. Schwarz identified the species as Thauma- toglossa (Axinocerus) americana Jayne, of which he had pre- viously taken two specimeus in Lavaca Co., Texas, on the flow- FIG, i.

A third specimen, which he took in the gall of a Coccid (Ollifflella cristicola Ckll.) on oak (Quercus oblongifolia) in the Santa Rita mountains, southern Arizona, is much larger and may represent another species of the genus. I bred sixteen specimens in all, four of which are males. The accompanying figure (fig. i) illustrates the antennae of both sexes.

Head without a spine or tubercle near the antennae; ocelli amber-colored, blackish-edged behind; antennae moderately long and finely pilose; basal joint one-third longer than the head, gradually curved, brown, with a black line exteriorly and a few black dots; the black line even reaching the antenniferous tubercle; second joint a little longer than the first; the third nearly equal in length with the sec- ond, both joints about half as thick as the basal joint, black, narrowly yel- lowish-white at base; terminal joint shorter, fusiform and orange-colored. Rostrum reaching the middle coxae, light brown, black at tip. Thorax broader than long; the disk feebly convex, in the middle a longitudinal narrow, smooth whitish line; lateral margins slightly sinuate anteriorly, and obtusely rounded posteriorly near the humeri ; the anterior margin less than half as broad as the posterior; the latter considerably depressed and straight, the transverse raised line above the margin well defined.

National Museum. 12 ENTOMOLOGICAL SOCIETY This species very much resembles A. armigera Say in form and colors, but can easily be distinguished by the absence of the spines on the head and by the differently-shaped cT genitalia. It differs from the common squash bug (A. tristis De Geer) in having a comparatively shorter and broader thorax and in lacking the stripes on the head. The species is referred to by Dr. F. H. Chittenden, in an article on the life history of the horned squash bug, published in Bulletin 19, new series, U. S. Department of Agriculture, p. 30, 1899. Mr. Caudell said that he had just returned from Cambridge, Mass., where he spent several weeks in the study of Scudder's types of North American Orthoptera in the Museum of Compar- ative Zoology. He stated that the Scudder collection is now well cared for by the curator of the Museum, Mr. Samuel Hen- shaw, although it is obvious that during the prolonged illness of Dr. Scudder it had suffered from neglect. With the exception of those groups lately revised by Scudder, the collection is not as well arranged as might have been expected. Mr. Caudell men- tioned short visits he had made, before his return to Washington, to museums in New York, Brooklyn, and Philadelphia. At Wel- lesley, Mass., also, he had visited Dr. A. P. Morse, and had had the opportunity of examining his collection of Acrididae un- doubtedly one of the finest collections in this family in the United States. Mr. Benton reported that he had seen a comb of the giant honey bee (either Megapis dorsata or M. zonata) in the Philip- pine exhibit at the World's Fair, St. Louis, Mo. It was attached to the under side of the limb of a tree and measured about i feet in width by some 3 feet in length. There were 4^ cells to the linear inch, or 20 to the square inch, while the thickness of the comb where brood had been reared was i 7-16 inches. Mr. Benton stated that the workers of the giant bees are about as large as queens of Apis mellifera. Mr. Banks showed a collection of several species of Hymen- optera whose sleeping habits he had observed, During last summer he discovered a colony at Falls Church, Virginia, about a mile distant from the one found by him two years ago. 1 The 1 Sleeping Habits of Certain Hymenoptera. By Nathan Banks. Journ. N. Y. Ent. Soc., x, No. 4, pp. 209-214, December, 1902. OF WASHINGTON. 13 colony, or* sleeping place, was tenanted by some eight or ten different species. Although he noticed a few 9 $ , most of the specimens observed were cT cT . Small bees were found in closed blossoms of the lace flower, or wild carrot (Daucus carota) , while bumble bees rested under the edges of certain flowers. Wasps belonging to the genus Ammophila held on to grass stems by their mandibles, the body extended straight and wings closely folded. Some other species use their mandibles in the same way, but Ammophila is the only insect which, in some cases, uses its mandibles exclusively for this purpose, the legs not touching the stem. Mr. Banks referred to his recent visit to the Museum of Comparative Zoology at Cambridge, Mass., where he made an examination of Hagen's collection of Neuropteroid insects and Emer ton's collection of spiders. Some of Keyserling's types of spiders, also, are deposited in the Museum. He stated that Hagen's collection has not been rearranged but is kept intact just as Hagen left it. This Mr. Banks considered most com- mendable and a policy which should be more generally followed. Mr. Caudell mentioned instances which have come under his observation of the mating of different species of Melanoplus, Sckistocerca, and other Orthoptera. The Morse collection of Acrididge, he stated, contains a fine series of intergrades. The subject of hybridization was discussed by Messrs. Piper and Gill, the latter stating that so-called new genera in fishes have been based upon hybrids between different genera. Dr. Dyar read the following paper: OUR PRESENT KNOWLEDGE OF NORTH AMERICAN CORETHRID LARVAE. BY HARRISON G. DYAR. Having discussed, in conversation with Mr. Coquillett, the relationships of the Diptera allied to the Culicidae, it seemed to us a more natural arrangement to separate the true mosquitoes into a distinct family on the character of the presence of the proboscis, and remove the non-biting forms, the old Coreth- ringe, placing them with the Dixidae as a second family, under the name Corethridse. In the larvae of this group the mouth brushes are somewhat developed, and in other characters they approach the true mosquitoes. 14 ENTOMOLOGICAL SOCIETY Dixa is the most generalized form and is a surface feeder, taking small vegetable particles by the rapid motion of its mouth parts. The air tube is well developed, but sessile, and there are false abdominal feet to assist the larva in ascending the water film at the margin, as is its habit. From Dixa can be derived not only all the other Corethridae, but the Culicidae as well. Anopheles, for example, is very close to Dixa in many characters. Except Dixa, all the Corethridae are predaceous, feeding largely on the larvae of the true mosquitoes. Next to Dixa comes Eucorethra, with its air tube still sessile, but the mouth parts modified for its predaceous habits. It is still nearly a surface feeder, lying flatly in the water. Corethrella is a fur- FIG. 2.

Corethra shows a development in a different direction. The air tube is elongated, but apparently could not be adapted to the requirements of the larva, as it became necessary for it to sink deeper and deeper in the water, so it has begun to be dis- used. The horizontal position is still maintained by the forma- tion of air bladders, one pair in the thorax, a second near the end of the abdomen. These are enlargements of the tracheal tubes and are joined by them to the air tube. It would seem that this fortunate arrangement supplied the larva with air- reservoirs, so that it is able to stay long below the surface and frequent the depths where it finds its subsistence. OF WASHINGTON. 15 Sayomyia has accomplished a still further specialization along these lines. It has dispensed with the air tube entirely and the trunks of the tracheal tubes as well, while it floats like a trans- parent ghost deep in the pool, carrying its four sacs of air which are now never connected with the air above. We suppose that the air in these sacs is replenished by diffusion through the body walls from the air dissolved in the water; but the character appears to us as a very remarkable one which would not have been antecedently thought possible. The Corethridae, as here limited, include 2 3 species described from North America. Of these we know the larvae of 15 more or less completely. There are no unknown genera, and it is probable that the unknown species of Dixa and Sayomyia are similar to the known ones. Indeed some of the species of Dixa may be synonymous ; but on the other hand, there are prob- ably a number of forms to be discovered. The subject has been very little worked. The following synoptic table will separate the known larvae : 1 . Air tube present 2 Air tube absent, larvae aquatic. . 7 2.

BY ROLLA P. CURRIE. About a ye?r ago the writer gave the Society a general ac- count of the Kootenay District of British Columbia and of the three months spent there by Dr. Dyar, Mr. Caudell and himself in the study and collection of insects. The dragonflies consti- tute a group in which he is especially interested, but the effort to collect a good series of insects in all Orders prevented his devoting as much attention to the Odonata as he might have wished. Nevertheless, the collection of Kootenay dragonflies 1 Mr. Johannsen separates the American form of plumicornis under a new name because the four spines of the antennae are equal in length. But Mr. Knab has called my attention to Weismann's article (Zeits. fiir wis- sensch. Zool., xvi, 1866) where the spines are shown of equal length in the European form. But Dr. Felt repeats the statement of the difference (N. Y. State Mus., Bull. 79, 370, 1904) and figures the leaf -like appendages of the two forms, which appear slightly different. I therefore provisionally use Mr. Johannsen's name. S. hudsoni Felt does not seem to differ in any tangible manner. 2 Mr. Johannsen cites my figure of this species as indicating but two hairs on the anal segment. The figure is drawn as if of one side only; there are in fact four hairs, two on each side. To judge by Dr. Felt's figures, S. albipes Joh. differs in the smaller development of the serrations on the edges of the appendages. 3 This may be the larva of 5. punctipennis Say or 5. rotundifolia Felt. The specimen was collected by Mr. F. Knab at Springfield, Mass. Dr. Felt says of rotundifolia that the leaf-like appendages have several rather large irregular teeth at the base of the long pointed process. In the form before me there is scarcely a trace of an irregularity anywhere, and it is, therefore, probably a distinct species. It may be called Sayomyia knabi, new species.

In addition there are five specimens from Vancouver Island collected by Dr. Dyar, representing four species not included in those from the Kootenay country, namely, Lestes congener, ALschna con- stricta, Sympetrum costiferum and 5. mcinum. While at Banff, Alberta, the writer took an undeter- mined 9 of jEschna; and Mr. N. B. Sanson, Curator of the Park Museum at Banff, subsequently sent him for determina- tion three specimens of Sympetrum scoticum, a species which in all probability occurs in portions of British Columbia.

The concluding paper was by Mr. Banks, and entitled : ARACHNIDS FROM COCOS ISLAND. BY NATHAN BANKS. Cocos Island, situated in the Pacific Ocean some distance off the west coast of Mexico, has been rarely visited by naturalists. The only spider previously recorded from the island is Argy- roepeira nigriventris Keys., which was taken by the Hopkins- Stanford Galapagos Expedition. A few years ago Dr. Paul Biolley of San Jose, Costa Rica, visited the island, and several papers have been published on the results of his trip. The Arachnida were sent to me for examination, and although few containjone or two interesting things. The most important is a Phalangid representing a new genus. There were eight spe- cies in the collection, six spiders, and two Phalangids. The types are in the collection of the writer. ARANEIDA. Gasteracantha hexacantha Fabricius. Several specimens of the usual type. This is a widely dis- tributed species in the tropics. Gasteracantha biolleyi, new species. Cephalothorax black; legs and sternum black; abdomen yellow, with black spines and marks; a band connecting the larger lateral spines, an oblong spot near base of anterior spines, and a crescent each side in front; from the black band there is a mark extending to the posterior spines; all the sigillae are on these black marks. The venter is black, with many small yellowish spots. In shape it is much like G. cancriformis, OF WASHINGTON. 21 but the posterior lateral spines are larger and more recurved than in that species.

Marlatt. 24 ENTOMOLOGICAL SOCIETY Mr. Schwarz exhibited specimens of a Ptinid beetle (Nip- tus hololeucus Faldermann) received from Prof. James Fletcher, Entomologist of the Canadian Government, who reported that it was a great nuisance in houses in Montreal. He stated that some years ago 1 he had published the prediction that the im- portation into America of this omnivorous beetle was only a question of time. He reviewed the literature on the beetle in reference to its distribution and economic importance. Dr. Ashmead announced that the National Museum had received from Father Robert Brown of Manila some Philippine fig-insects (Agaonidae) the first fig-insects to be recorded from the Philippine Islands. They fall in the Australian genus Kra- dibia. With them were specimens of the inquilinous or para- sitic Idarnines belonging to the genus Sycoryctes, first described from Java. Dr. Ashmead stated, further, that in a collection of insects from Mr. Charles S. Banks, the Entomologist of the Philippines, were specimens of Hymenoptera belonging to Oxybelus and Prosopis two genera not before on record from the Philippine Islands. Another addition to the list of Philippine Hymen- optera from the same source is the nearly cosmopolitan ant Solenopsis geminata Fabr. Dr. Hopkins exhibited a branch of juniper from Vermijo, New Mexico, showing the work of a new Scolytid beetle belong- ing to the genus Phloeosinus. The tree, from which the branch was cut on May 6, 1903, was felled during the summer of 1902. Live beetles were noticed on the branch on July 24 of the pres- ent year, and now, one year and seven months after the branch was collected, some of the beetles are still alive and running about. Mr. Heidemann showed specimens of Hemiptera belonging to the genus Homalocoris, and probably representing the Mexican species guttatus of Walker, collected at Flagstaff, Arizona, during the past season by Mr. Webb. There are now in the National Museum collection ten specimens from Arizona of this interest- ing species. The first of these were found by Mr. H. G. Hub- bard in the Chiricahua Mountains ; later it was collected by Mr. 'Can. Ent., xxvnr, p. 178, 1896. OF WASHINGTON. 25 Schwarzin the Santa Rita Mountains, and still later by Messrs. Schwarz and Barber at Williams. Lastly it has been found by Mr. Webb, as above stated. Mr. Heidemann added that Ho- molocoris and another genus, Hammatocerus, form a distinct subfamily of the Reduviidae known as the Hammatocerinae. This is the only species of Homalocoris which has been reported north of the Mexican boundary. Mr. Barber exhibited an original photograph of a wasp nest from Brownsville, Texas, made by the Vespid Gaba (Nectarina) mellifica Say. He was told by the negro who had possession of the nest that these wasps produce a palatable honey and that it is customary for the Mexicans to secure the nests when small and keep them until of full size, then destroying the wasps and extracting the honey. The nest was similar to those of our common paper-making wasp, Vespa maculata, except that in its lower portion the cells were exposed. It was globular in shape and about nine inches in diameter not of full size, according to the negro, who, after cautiously inserting a knife into it, withdrawing it and examining the blade, asserted that there was yet too little honey contents to make it worth while to open it up. Mr. Barber said he tried to taste the honey, but the amount on the knife blade was so small that he could scarcely detect any flavor. Thomas Say, 1 in the paragraph following his original description, says of this species that near Jalapa, Mexico, his attention was attracted by a group of In- dians eating honey from a paper nest. He found that the honey had a pleasant taste and inferred from the gestures of the In- dians that the nest was obtained from a tree. Mr. Ashmead remarked that it was of interest, in this connec- tion, to note that another Vespoid wasp (Celonites abbrematus Villers, of the family Masaridae), coming from Algiers, is said to be a honey-maker. Mr. Benton expressed some doubt as to whether the substance produced by the wasps is real honey, but thought it might consist of brood food accumulated in the cells. Mr. Titus stated that he had received from Trinidad, from Mr. H. D. Chipman, a Vespid from which honey is said to be obtained. 1 LeConte's Edition, Vol. u, p. 769. 26 ENTOMOLOGICAL SOCIETY Mr. Schwarz reported that on his recent visit to Texas he learned that the sweet-potato beetle (Cylas formicarius Fabricius) had been found in great numbers along the coast of Texas. This beetle came originally from Madagascar and has become introduced into tropical and subtropical portions of the western hemisphere. For some time past it has been known from Florida and Louisiana, but its discovery in Texas indi- cates that it is now to be found throughout the Gulf region from Florida to Texas and Mexico. Mr. Schwarz stated that he had found it particularly abundant in Cuba, but not so injurious there as elsewhere, since the common variety of sweet potato in that country has run wild and is a troublesome weed, the luxuriant vines overgrowing everything. The beetle is known to Cubans by the name "Tetuan," tradition having it that it first invaded Cuba in the same month and the same year when the famous battle of Tetuan was fought by the Spanish army against the Sultan of Morocco, February 4, 1860. Mr. Currie said that he had found another species of the genus very destructive to sweet potatoes in Liberia, West Africa, and Mr. Schwarz added that the Liberian species is probably Cylas turcipennis Boheman, originally described from Java. He said that there are about ten species known in the genus, all of them coming originally from tropical Africa or the Malay Archipelago. Dr. Hopkins stated that while investigating insect damage to hickory trees at Clark's Station, Missouri, on July 10, 1904, he found seven or eight small larvae attached to a Cerambycid larva (Neoclytus luscus] in the sapwood of a hickory tree killed by Scolytus ^-spinosus. The larvae were decidedly parasitic, and were supposed at the time to be braconid, but when (on July 20) they had completed the destruction of Jtheir host, and formed peculiar flattened cocoons, he recognized the cocoons as those of a beetle which he had often observed in the larval mines and pupal cases of Cerambycid larvae, and while at the West Virginia Station he had bred an adult. As near as he could remember, the bred beetle is a Colydiid, probably identi- cal with Bothrideres contractus. He says that there is no ques- tion regarding this larva being a true external parasite, as much so, indeed, as a braconid. A microscopic examination of the OF WASHINGTON. 27 cocoons shows that the ventral portion by which it is attached is composed of silk-like threads woven in a similar manner to that of hymenopterous cocoons. The dorsal covering is less silk-like, and quite brittle. Mr. Schwarz remarked that a spe- cies of Bothrideres has been recorded by Mr. Coquerel, in one of the earlier volumes of the Ann. Soc. Ent. de France, as a para- site of a Cerambycid larva ; and that another species, Bothrideres cactophagi Schwarz, had been recorded by Mr. H. G. Hubbard (in Psyche, vol. vm, Suppl. I) as a parasite of the larva of a large Calandrid beetle, Cactophagus validus L,ec. Mr. Benton read the following communication by Mr. G. W. Kirkaldy, extracted from a letter addressed to him as Corresponding Secretary of the Society : THE HISTORICAL METHOD IN TYPE-FIXATION. BY G. W. KlRKALDY. In the discussion on "Type-fixation" in a recent number of the Proceedings of this Society no mention is made of the "His- torical" method, and as the writer has noticed that this method has been quite ignoied in several recent discussions, for exam- ple, in the " Zoologischer Anzeiger," he will briefly outline it. By this method which has been adopted in the writer's forthcoming "List of the Genera of the Hemiptera," and which is also adopted by Mr. Prout, the well known English lepidop- terist, who is patiently investigating the nomenclature of the Geometrae each genus is treated absolutely independently; each is taken separately and the various applications of later authors, their restrictions and type fixations, considered with- out reference to other genera at all. Take, for example, the genera Neides and Berytus. Neides Latreille was Erected in 1802, for two species, tipularius and clampes; a year later, Fabricius founded Berytus with tipularius specified as type. In this case t'-e "Eliminators" would prob- ably admit two genera, as follows : 1. Berytus, with tipularius, and 2. Neides, with the species remaining, viz., clampes ; and this is in fact the view taken by Lethierry and Severin. The "historical" method would be as follows: 1. Berytus, 1803, type tipularius, 1803; 2. Neides, 1802, no type till 1804, when tipularius was fixed. 28 ENTOMOLOGICAL SOCIETY In the writer's papers on the bibliography of the genera of the Hemipterain "The Entomologist" l he considered that Berytus and Neides were strictly homotypical and that clampes required a new generic name ; as follows : 1. Neides L/atreille, 1802, type tipularius, 1804; Berytus Fabricius, 1803, type tipularius, 1803; 2. Berytinus Kirkaldy, 1900, type clampes, 1900. There is, in the opinion of the writer, no doubt that in 1802 to 1 804 only one genus would be recognized for these two forms, and indeed Latreille in 1804 so considered it. Clampes was not, he believes, treated as generically distinct till about 25 years later when the same author (Schilling) used Berytus for the one and Neides for the other. With rule No. i of Rothschild and Jordan, the writer cor- dially agrees and indeed has acted upon the principle from the commencement. of his studies. But No. 2 will, he hopes, not be recognized at all. It is at least contrary to the usual procedure of monographers of to-day. It must be noted, however, that certain of the older authors held to this rule; for example, Westwood, in 1839,2 writes: "The reader will observe that I do not here insist upon the necessity of placing a typical species at the head of the genus, because even our imperfect views of nature will enable us to see that such species ought often more naturally to be placed in company with others not arranged at the head of the genus, but I do insist that, where an author does not state the particular species which he regards as the type of his genus, we are bound to suppose that he would place it at the head of his genus." Though this statement in no way affects the types of other authors, the writer believes that in all Westwoodian genera dating from 1839, the first species must be taken as the type, if this be not otherwise specified. The paper evoked discussion from Messrs. Ashmead, Morris, Dyar, Piper and Schwarz, Dr. Dyar favoring the method which accepts the first species as type, while the others believed the method of elimination, although leading to unsatisfactory re- sults in certain cases, yet the one which is now most generally 'Vol. xxxm, pp. 238-243, 1900; Vol. xxxvii, pp. 254-258, 1904. * Mag.

The sup- posed generic differences may be at once discarded, since they are founded on the variable venation. The amount of white shading on the fore wings is likewise very variable, and it is this, I suppose, which has further influenced the continued separation of -the forms. Under the specific name melanogrammos Zell., Dr. Hulst gives the variety diluculella Grt., with talleolalis Hulst as a synonym. This is wrong, I believe, as diluculella Grt. is robustella Zell., the pine feeder, as given by Sir Geo. F. Hampson. 1 But Hampson continues talleolalis Hulst as a synonym to diluculella, Grt., which is wrong again, as this form should be attached to militella Zell. Hulst 's type was one 9 from Colorado, and I would use the name talleolalis to designate the western race of militella, which is larger, more diffusely marked, the lines shaded and broadened. I have it from Aweme, Manitoba (Criddle), Winnipeg, Manitoba (Hanham), Stockton, Utah (Spalding), and southern Arizona (Poling). The white shadings vary from extensive to absent. There is another form, a true variety, not a race, which I would designate by the name clemensalis, new variety. It has the thorax and base of fore wing shaded with dull ocherous. It was mentioned by Clemens, but not named. The variety occurs occasionally in eastern material. I have three before 'Transfent. Soc.

I am inclined to view Ragonot's three names as referring to forms of one species, most appropriately named -variella. I have five specimens from different parts of Texas which I refer to it. Attacapa callipeplella Hulst cannot be separated generically from Pococera. The species may be recognized by the absence of dentations in the outer line. Subfamily Myelois annuliferella^ new species.

The Western form, as I have noted, is distinguishable as a race, being larger, with the markings heavily contrasted. It is unfortunate that the names turbatella, bella or franconiella cannot be used for it ; but these were all based on Eastern specimens. I have the Western form from Manitou, Col.

I think that this species 2 will prove to be the same as packar- della Rag. I have now additional specimens from Phoenix, Arizona (R. E.

I suspect that Ragonot's single type may have been in bad condition, so that the lines were not visible. Zophodia perdubiella, new species.

I can match Ragonot's figures of coloradensis and morrisonella, but there is nothing that would fit the form olbiella Hulst, which is said to have ' ' all the wing washed with vinous red." Now I have a 9 specimen identified by Dr. Hulst as olbiella, which is entirely washed with vinous red; but it is Staudingeria albipennella, not Heter- ographis morrisonella. I am aware that Dr. Hulst' s determina- tions are not generally reliable and that his description of olbi- ella covers ochraceous as well as brown forms ; therefore, I would refer olbiella as a synonym to morrisonella, not as a variety. The name morrisonella will stand for the dark form and colora- densis for the pale one. The two are not sharply separated, but intergrade. Homoeosoma oslarellurrr, new species.

BY NATHAN BANKS. Tyroglyphids have been found in many situations where one would never expect them, nor easily explain their presence. They have a minute migratory stage which may be attached to various insects, and in this way they may be transported far from their birthplace. It was one of these mites that an Eng- FIG. 6 Carpoglyphus alienusi 9 . lishman thought he had produced by means of electricity. Not the least remarkable of the many strange habitats, is that in the following case : Early in 1904 Dr. J. de Haan, Director of the Geneeskundig Laboratorium te Weltevreden of Batavia, Java, sent to me for determination some mites found in the urine of a patient affected with a kidney disease. Every time he passed urine some of these acarians were found surrounded in pussy matter. OF WASHINGTON. 41 There seemed no doubt to Dr. de Haan that it was a genuine case of endoparasitism. An acarologist familiar with the al- leged habitats of various Tyroglyphids cannot suppress his sus- picions in the case. Yet, as it is stated that mites were found in every passage of urine, it seems impossible to account for FIG 7, Cctrpog lyphus alienus; a, genital openings, Cj and $ > b, mandible. FIG. 8. Carpoglyphus alienus, legs I and IV. their adventitious occurrence. Were the mite of some other family it would not be so strange, but that a Tyroglyphid could get to the internal organs, other than the alimentary tract, seems beyond belief. Yet there cannot be the slightest doubt as to the systematic position of the mite as can readily be seen from the figures. The nature of the genital openings and the position of the long bristle on tibia I seems to place the speci- mens in the genus Carpoglyphus. The caroncles are not as dis- tinct as in the one known species of this genus, but the position of the bristle on tibia I is unique. I shall therefore simply de- scribe the species leaving the question of its occurrence to the future. 42 ENTOMOLOGICAL SOCIETY Carpoglyphus alienus, new species. Body nearly elliptical, rather pointed in front, broadly rounded behind; without separation between cephalothorax and abdomen; with but few hairs above; a pair in front between legs I and II, a submarginal pair above leg IV, and two pairs of longer ones behind; the median pair are on the dorsurn, the other pair on the posterior margin; a large dark elliptical spot each side behind. Legs of moderate length and slenderness; leg I has the long hair from near middle of penultimate joint; the basal clavate hair of tarsus is curved near tip. The caroncles are not very distinct, but the claws are large. In leg IV the tarsus is fully twice as long as the metatarsus. The vulva of the female, which is well forward and intercoxal, shows two divari- cate lines, and each side two oval suckers. The male opening is farther back, and nearly three times as long as broad, rather broader behind, and the sides slightly concave; there are two circular suckers each side.

OF WASHINGTON. 43 appendix erects seven new genera, describing the venation and genitalic characters of each. The venational characters seem to be of an indefinite nature, and we might as well frankly re- gard the genera as founded on the genitalia alone. These cer- tainly show well marked and distinctive characters. I have received from Dr. Felt photographs of many of his slides and have had others prepared by the kindness of Mr. H. S. Barber. It is of especial interest that the genitalic groups run largely parallel to those defined on larval characters, in some cases con- FIG. 9.

A case in point is that of Janthinosoma musicum, Culex jamaicensis and Taznio- rhynchus signipennis. These larvae are very peculiar and essen- tially alike. The adults have been considered unrelated; but the 'genitalia are in some respects very similar and place these forms close together. This leads me to conclude that the genitalic groupings, where reinforced by the larval ones, show natural divisions, and I am, therefore, in accord with Dr. Felt ENTOMOLOGICAL SOCIETY in using them as the basis for genera. It is true that in general practice other characters than these are preferable, owing to the necessity of preparing the specimens and to the fact that the characters are shown by one sex only, and that the one not gen- erally collected. I believe, however, that since the groups are natural ones it is probable that other recognition characters will be found. If they should not be, it might be better to reduce the genitalic genera to subgeneric rank, for practical reasons, without thereby losing sight of their value. It seems inevitable that the genus Culex shall be divided, and the geni- talic divisions are more natural than those recently founded on scales and papal structure. As to the latter it is necessary to remove and mount the palpi, which is as practically objection- able a process as any connected with the study of the cT geni- talia. The sketch herewith of Grabhamia cantator Coq., shows the names applied to the different parts. They vary much in amount of development as well as in shape in the different species. Anopheles shows the simplest arrangement, scarcely distinguishable from the Corethrinae. This is in accord with the larval characters, since Anopheles larvae are very close to some Corethrid forms, as Eucorethra and Dixa. The Culicinae have a small articulated tip to the terminal segment of the clasper, which appears to be lacking in the Aedinae, although in UranotcEnia sapphirina there is a small spine much resembling it and probably representing its rudiment. The species of Culex show the most differentiation, especially in the true Culex or pipiens group and these are the most specialized larvae. We have thus a concordance in general as well as special characters between genitalic and larval structure I have thrown the forms known to me into a synoptic table of genera, which follows. A few new names are supplied to fill gaps left in Dr. Felt's groupings or as corrections. Nine gen- eric names, out of a total of thirty-one credited to our fauna, are omitted, as I have had no material to dissect. 1.

Nine species are recorded from North America, viz: maculipennis Meig., plumbeus Hal., bifurcatus Linn., punctipennis Say, pseudopunctipennis Theob., francisca- nus McC., barber i Coq., crucians Wied., eiseni Coq. 46 ENTOMOLOGICAL SOCIETY Genus CELLIA Theobald. Type: pulcherrima Theob. The genitalia will probably prove similar to those of Anopheles. I have not seen them of either of the species recorded from North America, viz: argyrotarsis Desv., albipes Theob. Genus CYCLOLEPPTERON Theobald. Type: grabhamii Theob., the only species recorded from our region. The genitalia are unknown to me. Genus ARRIBALZAGIA Theobald. Type: maculipes Theob. This species is recorded from Trinidad and will doubtless be found in the southern portion of our region. The genitalia have not been examined. Genus PSOROPHORA Desvoidy. Type: ciliata Fab. We are credited with three species, viz: ciliata Fab., howardii Coq., scintillans Walk. The genitalia of ciliata have been figured by Dr. Felt. Genus MEGARHINUS Desvoidy. Type: hczmorrhoidalis Fab. We are credited with seven species, viz: rutilus Coq., portoricensis Von Rod., ferox Wied., grandiosus Will., h&morrhoidalis Fab., longipes Theob., separa- tus Arrib. Mr. Barber has made me a nice mount of the geni- talia of portoricensis, from which the characters given in the table were taken. Genus STEGOMYIA Theobald. Type: fasciata Fab. Besides this species, sexlineata Theob. may occur with us. The genitalia of fasciata are distinctive as may be inferred from the preceding table. Genus PNEUMACULEX, new genus. Type: signifer Coq. This species is peculiar in many ways and deserves a distinct generic appellation. The larva has be- sides the peculiar dorsal plate an enlargement of the tracheal tubes into a sort of bladder in the thorax, suggesting Corethra. In the cT genitalia the side pieces are conic, without apical lobe ; basal lobe small but bearing two stout setae; terminal clasp slender, enlarged a little outwardly with a multiple articulated tip. Harpes short, chitinous, concave, with trifid apex ; harpa- gones small, slender, chitinous, acute; another pair of appen- dages more basally placed, shorter than the harpagones, with a terminal hook; a median, divided, double-tipped membrane (unci?). OF WASHINGTON. 47 Genus TJENIORHYNCHUS Arribalzaga. Type: titillans Walk. Theobald takes fasciolatus Arrib. as the type of T&niorhynchus, but the first species is t&niorhynchus Arrib. (nee Walker) = titallans Walk., and should be the type. This species is also the type of Mansonia Blanchard, which will become a synonym of Tceniorhynchus. The species has been recorded from Trinidad and will doubtless be found in the southernmost part of our territory. I do not know the geni- talia. Genus COQUILLETTIDIA, new genus- Type: perturbans Walk. Theobald places this species in Tceniorhynchus Arrib., but not correctly, I believe. The geni- talia are peculiar. Dr. Felt has prepared them from a specimen which I sent him, but the figure is not r. produced in his bulle- tin. The characters may be gathered from the table. Four species are referred here, viz: richardii Fie., perturbans Walk., confinis Arrib., nigricans Coq. Genus FELTIDIA, new genus. Type: jamaicensis Theob. Dr. Felt has taken jamaicensis as the type of Grabhamia, but Theobald mentions first dorsalis Meig. Of jamaicensis, Theobald gives a rough figure and Felt a good photograph. We have three species at present referable here, jamaicensis Theob., cyanescens Coq./signipennis Coq. Genus JANTHINOSOMA Arribalzaga. Type: dis crucians Walk. We have five species, viz: musi- cum Say, posticatum Wied., lutzii Theob., discrucians Walk., varipes Coq. Dr. Felt has prepared the genitalia of musicum and lutzii which are much alike. He has figured the former. Genus JOBLOTIA Blanchard. Type: ni-veipes Theob. The name is a substitute for Theo- bald's Trichosporon (nee Trichosporus Macq.) The single spe- cies is recorded from Trinidad, but probably occurs with us. I have not seen the genitalia. Genus ECCULEX Felt. Type: syhestris Theob., the only species. It has most re- markably distinct genitalia and is apparently not at all allied to Grabhamia as one would have supposed. Dr. Felt has pub- lished a photograph. Genus PSEUDOCULEX, new genus. Type: aurifer Coq. As noted below, I think this is a distinct generic type. The characters are given in the preceding table and in Dr. Felt's figure. 1 """pi. 33, %. 2. 48 ENTOMOLOGICAL SOCIETY Genus CULICELSA Felt.

Marlatt, No. 1440 Massachusetts Avenue, N.W., President Banks in the chair and Messrs. Ashmead, Barber, Burke, Busck, Couden, Currie, Fairchild, Fiske, Girault, Hinds, Hopkins, Marlatt, Patten, Schwarz, Stiles, Ulke, and Webb, members, and Messrs, Brues, Hooker, Lantz, Nawa, Pierce, Sasscer, and Sanders, visitors, present. The president appointed, as the new publication committee, Messrs. Currie, Schwarz, Ashmead, Titus, Busck, Barber, and Heidemann. Dr. H. G. Dyar was elected to represent the Entomological Society as a Vice- President of the Washington Academy of Sciences. The treasurer presented his report to the society. The resignations of Mr. T. Wayland Vaughan from active membership and of Prof. B. E- Fernow from corresponding membership were presented and accepted. Mr. W. Dwight Pierce of the Bureau of Entomology, U. S. Department of Agriculture, was elected an active member of the Society. The Annual Address of the retiring president was then read by the Recording Secretary; 66 ENTOMOLOGICAL SOCIETY ANNUAL ADDRESS OF THE PRESIDENT/ THE LINN^EAN GENERA. OF DIPTERA. BY D. W. COQUILLETT. To the systematic entomologist the writings of Linne possess an interest not shared by those of any other author. Coming at a time when pure science was being freed from fiction, he did yeoman service in the direction of placing the science of Natural History upon a firm foundation. This is particularly true in regard to the classification of natural history objects, and it is interesting to trace the evolution of this classification as given in the various authorized editions of his immortal Sy sterna Naturce and of his Fauna Suecica. Of the thirteen editions of the former work only five were issued by the con- sent and under the supervision of Linne himself; these are the first, second, sixth, tenth and twelfth editions. The other eight are reprints and usually abridged, the exception being the thirteenth edition, which contains considerable additional matter contributed by Gmelin, who edited it. In the editions by Linne the various objects are divided into classes, orders, genera and species. The separation of the orders into families was at that time unknown. The first edition of the Systema Natures, which appeared in the year 1735, treated the insects as class five and divided them into four orders; COLEOPTERA, which contained the Coleoptera as at present understood, together with the Orthop- terous genus Forficula; ANGIOPTERA, comprising the Lepi- doptera, Neuropteroid insects, Hymenoptera excepting the ants, Diptera and the Toredo; HEMIPTERA, comprising the Orthopterous genus Gryllus, the modern order Hemiptera, and the scorpions; finally the APTERA, which included all the wingless forms, now placed in four different orders, and some of the Crustacea. The Diptera are comprised in the single genus Musca, which is brieflydescribed, and under it are ranged, as species, Musca (different species not named), CEstrum veterinum, CEstrum lapponicum, Tabanus, Culex, Tipula, Toredo navalis, and the ant-lion. OF WASHINGTON. 67 In the second edition, published in 1740, the same four orders are recognized, but the name of one of them, Angioptera, is here changed to GYMNAPTERA. The Diptera are arranged as in the first edition except that only four species are listed, namely, Musca, Tabanus, Culex and Oestrum, while after each is given its vulgar or common German name. The first edition of the Fauna Suecica appeared in the year 1746. In this work no less than seven orders of insects are recognized, the names of four of them appearing for the first time, namely, NEUROPTERA, LEPIDOPTERA, HYMENOPTERA, and DIPTERA. The names, Angioptera, of the first edition of the Sy sterna Nature, and Gymnaptera, of the second edition, are dropped entirely in the present work, while the other previously proposed names Coleoptera, Hemiptera, and Aptera, are retained, but in a restricted sense. In the Diptera the number of genera have increased from the one, given in the first and second editions of the Sy sterna, to seven, namely ; (Estrus, Asilus, Hippobosca, Tabanus, Musca, Culex, and Tipula. This work marks a very great advance in the matter of classification, especially in regard to genera and species. The genera are not described, but the species are characterized at considerable length, although not named specifically. The next, or sixth, edition of the Sy sterna Nature appeared in the year 1748, and is practically a repetition of the preceding work, but with the descriptions of the species omitted. The genera, however, are briefly described. The tenth edition was published in 1 758. Here the binomial system of nomenclature is given in its more perfected form, each species having a separate name. The orders are as in the sixth edition. In the Diptera three new genera are added, namely, Empis, Conops, and Bombylius. The second and last edition of the Fauna Suecica appeared in 1 761 ; the orders in the insects and the genera in the Diptera are the same as given in the tenth edition of the Sy sterna Natural. The twelfth and last authorized edition of the Systema Natures was published in two parts; the insects are comprised in the second part, which bears the date of 1767. The orders and genera of the Diptera are the same as in the tenth edition. 68 ENTOMOLOGICAL SOCIETY It will thus be seen that two of these works mark very im- portant epochs in the classification of insects; these are, the first edition of the Fauna Suecica, wherein the seven much more natural orders of insects are instituted and many new genera founded ; and the tenth edition of the Sy sterna Natures, in which the binomial system of nomenclature is placed upon a firm basis. A few words in regard to the real name of this great naturalist may not be out of place. Students of his published writings have been sorely puzzled over the fact that whenever he had occasion to sign his name, whether in the dedication of the volume or at the end of the preface, he at first wrote his name Linnaeus, but in his later works it appears as "von Linne." Historians inform us that the grandfather on the paternal side was a peasant by the name of Tiliander, and that his son, the father of the naturalist, in accordance with the custom then prevailing in Sweden, changed his name to Linnaeus at the time he entered the University, and his son also used this name until the year 1761, when the King of Sweden issued to him a patent of nobility under the title of Carl von Linne a curious admixture of German and French. It will thus be seen that Linnaeus was not his academic or assumed name, as some have supposed, but was his legitimate name, inherited from his father, and that it was later changed to von Linne by royal decree. Turning now from a consideration of one whose work com- prised the entire realm of nature, it may not be out of place here to call attention to a recent important event in the history of an organization whose object has been to investigate only one of the numerous branches of Natural History. In view of the fact that the year just passed marks the twentieth anni- versary of the founding of our Society, a brief retrospect of its history and work may ^ be of some interest to the members and others interested in its welfare. The Society took its inception on Friday evening, February 2Qth, 1884, in response to a call signed by Messrs. C. V. Riley, E- A. Schwarz, and L- O. Howard. At the following meeting, OF WASHINGTON. 69 held in the evening of March i2th, r a constitution was adopted, officers were elected, and the names of twenty-six persons enrolled as charter members. Of these twenty-six original members, nine have passed into the great beyond, while eight of the others have since abandoned the study of Entomology, leaving only nine of the original twenty-six members still in the ranks, namely: Lawrence Bruner, T. L- Casey, Otto Heidemann, L- O. Howard, Albert Koebele, Theodore Pergande, H. A. Schwarz, J. B. Smith, and P. R. Uhler. It is fervently to be hoped that many years will pass by before this list will be lessened by a single name! During the twenty-one years of its existence our Society has elected ten presidents, and while our constitution is silent on the subject it seems early to have become an unwritten law that the officers elected for any particular year were to be re-elected for the succeeding year. This rule was followed with a single exception; by an apparent oversight there is no recorded election of officers for the year 1897; those chosen for the previous year simply held their offices until their successors were elected and qualified. Up to and including the year above mentioned the presidents had held office for the prescribed two years each and had prepared an annual address at the close of each term, but during the following three years this rule was destined to be ruthlessly broken. The late lamented H. G. Hubbard was elected president of the Society for the year 1898, but ill-health prevented him from attending the meetings and preparing an annual address; he was re-elected president for the following year, but passed away before a month of the new year had elapsed. From the date of his demise on January i8th until the i6th of the following May the Society had no president, but at the latter date the first Vice- President, Doctor Theodore Gill, was elected president for the balance of the unexpired term. At the next annual election all of the officers were re-elected for the year 1900. During this year, as also the portion of the preceding one subsequent to the month of May, the Society was without a first vice-president. This break in the usual course of events resulted in our having two presidents during 70 ENTOMOLOGICAL SOCIETY the three years 1898-1900, while no annual address was delivered for either of these years. Each of the other presidents held office for two consecutive years, and one of them, Dr. Riley, the first president, was especially honored by the Society in that it elected him its president at four different times an honor never since conferred upon any of its members. During the twenty years of its existence our Society has published six volumes of its Proceedings; three of these appeared during the first eleven years, and the other three during the remaining nine years. These volumes are veritable storehouses of biological facts and also contain much matter of special interest to the student of systematic entomology, attesting the wide-awake interest and unremitting efforts of the members. Mr. Fairchild exhibited a collection of photographic repro- ductions of the portraits of famous botanists, published by Prof. Wittrock of Sweden. He called especial attention to a series of portraits of Linne at different ages, the first one taken when about 30 years of age and ending with a copy of a reproduction in wax taken at an advanced age. Mr. Schwarz, referring to Linnaeus, mentioned a published bibliography of the latter which is very little known or referred to. This is the one by Dr. C. A. Dohrn, President of the Ento- mological Society of Stettin, published in the Stettin Entomo- logische Zeitung. Dr. Stiles spoke in favor of the formation by the Washington Entomological Society of a collection of photographs of its members. He believed that this should be begun at once, since it would soon be difficult, if not impossible, to secure photographs of the older members, and the collection would very soon come to be highly prized. After some discussion Dr. Stiles's suggestion in the form of a motion was seconded and carried. Dr Hopkins read the following paper: OF WASHINGTON. 71 NOTES ON SOME MEXICAN SCOLYTID^E, WITH DESCRIP- TIONS OF SOME NEW SPECIES. BY A. D. HOPKINS. (In Charge of Forest Insect Investigations, Bureau of Entomology, U. S. Dept. Agr.) Chapuis (1869), Eichhoff (1868-' 79), and Blandford (1885- 1904), have described several hundred species of Scolytids from Central America and Mexico, but there has been com- paratively little recorded regarding their habits. Recently some information has been contributed in this line in an article by Prof. A. Iy. Herrera (El Progreso de Mexico, June 8, 1903) on a bark beetle injuring the white mulberry, and by Dr. S- J. Bonansea (in a pamphlet entitled "Birds and Insects," published by the Agricultural Society of Mexico, 1904), in which reference is made to extensive depredations by bark beetles on the pine forests in different sections of Mexico. The references to Scolytidae in both of these papers were based on preliminary identifications of species sent to the Bureau of Entomology by the authors. Considerable additional Mexican material has been received from Prof. Herrera, Dr. Bonansea, and Mr. E- Baumann. In response to a request from Dr. Bonansea for names and descriptions of new species, and further information in regard to the named ones, this paper is presented, in order that he may. include them in his forthcoming report on investigations of the causes of dying timber in Mexico. The Scolytidae received from these gentlemen represent nine genera and sixteen species, of which ten appear to be undescribed. Descriptions of these, with notes on other species from Mexico and their allies in the United States, follow: Platypus rugulosus Chap. Three females and one male, Michoacan, Mexico, in wood of "chocolate tree," received from Prof. Herrera. This is a common and widely distributed species in Central America and Mexico, and probably extends into the southern border of the United States. One specimen in our collection from California appears to be different al- though closely allied. Platypus pini, n. sp. Male type, length 5 mm. ; very elongate cylin- drical, 'piceous; legs and antennae lighter reddish. Head, prominent, nearly one-third as long and slightly broader than anterior width of prothorax; front broad, flat, opaque, pubescent and punctured, but the punc- tures are very shallow, of irregular size and often contiguous; the occiput 72 ENTOMOLOGICAL SOCIETY co ivex, with two broad, opaque, slightly impressed longitudinal spaces each side of a slightly elevated, smooth, shining median one, the remain- ing surface towards the eyes shining, sparsely punctured and with a few long, backward-curved hairs. Prothorax subopaque, as long as the basal width, narrower in front and deeply excavated in the sides for the anterior legs; distinctly punctured, denser each side of a faint, median, dorsal, smooth space and coarser near the anterior and posterior margins; posterior third with distinct impressed dorsal line; base bisinuate. Elytra, subopaque; base elevated and with a subacute margin; striae faintly impressed, narrow, shining, and with faint, shallow punctures; the interspaces subconvex, equally elevated towards the middle, not punctured except those on the sides, which have a row of very fine obscure ones; the declivity is darker, opaque, with shallow, shining punctures faintly evident; the third interspace is strongly elevated, carinate, with an acute apex and extending to the middle of the face of the declivity; five and seven are slightly elevated and acute but not extending much beyond the vertex; the apical process is divided into two distinct triangular teeth, outer one longer; the apex is deeply, obtusely emaYginate; the first interspace is not distinctly tuberculate on the vertex. C? Type. No. 7509 U. S. Nat. Mus., Chaleo, Mexico, October, 1903, in pine. Received from A. L Herrera, under his number 873. This is closely allied to a common (but undescribed) species which infests the pines in Arizona. Gnathotrichus nitidijrons n. sp. Female type, length 2.8 mm.; elon- gate, cylindrical, brownish; head and ventral portion black; the legs reddish. Head broad, slightly convex, shining, and punctured each side of a broad smooth median space, which extends from the anterior margin to near the vertex; pubescence fine and sparse; eyes large, emar- ginate; antenna club with two nearly straight indistinct sutures on the anterior face and with a few scattering long hairs. Prothorax more than half as long as elytra; posterior two-thirds with sides parallel; anterior third with sides and anterior margin broadly rounded, the latter faintly roughened with broad serrations; anterior half sparsely pubescent, finely asperate, the asperities coarser towards anterior margin and much finer and denser towards the vertex and sides; posterior half glabrous, opaque, finely indistinctly punctured. Elytra glabrous, except on de- clivity, which bears a few long hairs; striae not impressed, indistinct, faintly punctured; interspaces flat, faintly rugose; declivity with inter- spaces one and two slightly impressed and with slight elevation armed with a row of minute granules each side towards the vertex, while towards apex interspace one is slightly elevated and the others flattened and faintly rugose; the sides are not strongly rounded but narrowed towards the apex, giving it a slightly produced appearance. OF WASHINGTON. 73 9 Type. No. 7510 U. S. Nat. Mus., Michoacan, Mexico, in pine, Prof. A. L Herrera, collector, bearing his number 1047. This is allied to the common Eastern United States species G. materiarius Fitch, which infests the wood of pines from Maine to Florida and Texas, and Picea from Maine to the higher mountains of North Carolina. The Mexican species is distinct from materiarius by the broad, smooth, shining frontal space and the much more distinctly produced apex of the elytra. Gnathotrichus sulcatus Lee. One specimen, Chaleo, Mexico, October, 1903, received from Prof. Herrera under his number 872, and another specimen from Michoacan, in pine, under his number 1047. I fail to find characters of sufficient value to separate these specimens from G. sulcatus Lee., which I have found to be a good species and not the male of G. retusus Lee., as considered by LeConte (Proc. Amer. Philos. Soc. XV, p. 350). G. sulcatus is a common and widely distributed species in the Pacific Coast and Rocky Mountain regions. I have found it in Pinus, Tsuga, Pseudotsuga, Abies, Picea, Thuja, and Sequoia. Blandford evidently had specimens of this species, together with (as he himself suggests) representa- tives of one or two other species when he drew up his descrip- tions of G. consentaneus. Pityophthorus chaleoensis n. sp. Female type, length 2.6 mm.; elongate* cylindrical, dark, ferruginous; sides of prothorax and legs lighter. Head broad, flat, rather coarsely, densely, rugosely punctured and with epistoma- like elevation on the anterior margin; the face with a few scattering hairs and the margin fringed with long incurved yellow ones; eyes 'emar- ginate; antennal club small and sutures impressed on sides and face. Prothorax one-half as long as elytra; sides nearly parallel to anterior third, then narrowed to margin which is broadly rounded; nearly smooth; anterior rugosities confused, extending towards side margin; posterior half shining, with median smooth longitudinal space; punctures coarser and denser towards dorsal space, fine and sparse on sides; pubescence fine, sparse, recumbent. Elytra twice as long as prothorax; pubescence fine and sparse towards base, denser and longer on declivity; strial punc- tures in approximate rows on sides, confused towards suture, side margin and declivity; second interspace broadly, deeply impressed; the sutural interspaces elevated and roughened with a row of numerous acute granules; the third interspace rather strongly elevated and armed with a row of six or seven small, acute piliferous, granules; striae one and two obscure. 9 Type. No. 7511 U. S. Nat. Mus., Chaleo, Mexico, 74 ENTOMOLOGICAL SOCIETY October, 1903, in pine, from A. L- Herrera, under his number 872. This species is not closely allied to any known species north of Mexico, and apparently "is quite different from any of the nineteen species recognized from Central America and Mexico by Blandford. Pityophthorus herrcrai n. sp. Female type, length 2.5 mm.; elongate, cylindrical, piceous. Head broad, flat, finely rugosely punctured; pubes- cent and fringed with long, yellow hairs; the anterior margin with a smooth shining triangular elevation; eyes emarginate; antennae missing. Pro- thorax slightly more than half as long as elytra, slightly narrowed from base to anterior margin, which is broadly rounded, faintly roughened, but not serrate; anterior rugosities confused, extending toward side margin, where they are much finer; posterior half with distinct longitu- dinal space, broader towards base, not elevated; punctures rather coarse and dense, becoming very fine towards the sides, but without interstitial minute points; anterior half and sides with fine sparse pubescence; pos- terior dorsal surface glabrous. Elytra pubescent only towards side margin and on declivity; strial punctures irregular but in approximate rows the interspace towards the suture and side margin with an occasional puncture; declivity with sutural interspaces slightly elevated and rough- ened with a few small irregular granules; apex slightly produced; the second interspace broad, flat, shining; the third scarcely elevated, punctured, but without distinct granules; the first stria is close to the first interspace, faintly impressed and punctured; the second stria is close to the third interspace, distinctly punctured. Male type, length 2.55 mm.; differs from the female in the glabrous, shining, evenly punctured front, with strongly elevated, smooth, shining posterior margin, and a faintly elevated, shining lateral margin; antennae yellowish-red, club with two slightly curved sutures, basal joint glabrous, shining; prothorax with anterior rugosities coarser; posterior half with broader dorsal _ space ; elytra pubescent only along sides towards the margin, pubescence denser and longer on the sides of the declivity, but the vertex and face of the declivity are glabrous; the sutural and third interspaces more distinctly elevated and roughened with coarser granules. 9 Type.

One additional female with number 696 is smaller, 2.25 mm., but agrees exactly in other characters. This appears to come close to P. confusus, Bland., but differs in the smooth punctation of the prothorax instead of " inter- stitial punctation of minute points" mentioned in the descrip- tion of confusus. OF WASHINGTON. 75 Tomicus mexicanus n. sp. Female type, length 4.8 mm.; elongate, cylindrical, ferruginous, clothed with long fine hairs; declivity of elytra excavated and armed each side with three teeth, the first very small, acute the second triangular, acute the third widely separated, long, cylindrical and thickened toward tip. Head, front flat, subopaque, densely granulated with shining median impression and a small shining tubercle on the anterior margin; antennal club with two obscure, broadly curved sutures on the anterior face; the posterior face pubescent and with one indistinct broadly curved suture. Prothorax as broad as long; anterior two-thirds roughened with small asperities, becoming finer to- wards the sides; posterior third smooth, punctured, with narrow dorsal longitudinal space. Elytral punctures coarse, those of the striae coarser and denser than those of the interspaces, first to fourth in distinct row, but the punctures on the sides are densely confused. Male type, length 5 mm., same form and general characters as the female, except that the pubescence is less dense; the frontal impression deeper and opaque, the marginal tubercle more prominent, and the margin more distinctly granulated; the teeth of the declivity distinctly coarser, especially the first and second. $ and c? Types. No. 7513 U. S- Nat. Mus., Mexico City, Mexico, 1903, in firewood, Prof. A. L Herrera, collector, and bearing his number 865. Two additional males from the same lot are of the same size and color of the female type, and agree exactly with the secondary sexual characters in the male. This is evidently the species mentioned by Blandford (Biol. Centr. Amer., Vol. IV, Part 6, page 188), on the authority of Eichhoff, under T. concinnus Mann. It is, however, easily distinguished from specimens I have identified as concinnus by its reddish color and very much coarser puncture of the elytra and pro thorax. Blandford compared his specimens with one from California, which, although closely allied to concinnus, evidently represents an undescribed species. T. concinnus is a boreal form extending down the coast into the United States with the Sitka spruce, in which* it lives, while the California species is common in Pinus radiata in middle California and Pinus murrayana of the higher Sierras and extending, with this tree, as far north as Priest Lake, Idaho. Tomicus integer Eichh. The specimens in our collection from Mexico received from Mr. Blandford under T. plasto- graphus belong, without doubt, to T. integer Eichh., which is a good species, distinct from T. plastographus Lee., with which it has been confused. The type specimen of the latter which I have examined agrees with specimens from Monterey pine in California, but LeConte made the mistake in this, as he 76 ENTOMOLOGICAL SOCIETY did in many other cases, of including in his revision in the Rhynchophora characters of specimens other than the original type or types. There was only one specimen on which the original description was based, but in LeConte's revision a specimen from New Mexico was included which proves to be T. integer Hichh. I have found T. integer to be a very common species through- out the Rocky Mountain region, from Montana east to the Black Hills of South Dakota, and south to New Mexico and Arizona, from which it extends into Mexico. It infests Pinus ponderosa and Pinus monticola, but no evidence has been found that it is a primarily destructive enemy. T. plastographus Lee., seems to be confined entirely to the sections in California where P. radiata grows. Tomicus bonanseai n. sp. Female type, length 3.35 mm.; elongate cylindrical, dark reddish-brown. Prothorax slightly darker; declivity of elytra excavated and armed each side with four short acute teeth, the first smaller, and the second to fourth nearly of equal size, but the second and third are closer together and situated on a slight elevation of the margin. Head flat, opaque, densely granulated, clothed with short erect pubescence and with fine median elevated line from middle to anterior margin; antennae missing. Prothorax as long as broad, sparsely pubescent towards sides to anterior margin ; posterior half rather coarsely sparsely punctured, with smooth, shining dorsal space; sides parallel to anterior third, then strongly narrowed to apex. Elytra less than twice as long as prothorax, with short sparse pubescence towards the side margin and declivity; striae faintly impressed, punctures distinct and closely placed, slightly coarser towards the middle; interspace one narrow, two and three broad, flat and not punctured towards base, fourth to ninth sparsely punctured. Male type, length 3.35 mm.; yellowish-red (young example), differs from female in the narrower, more convex and more shining front, with the granules and punctures less distinct and with a more prominent subcarinate tubercle towards the middle; prothoracic punctures finer and less dense. Elytral striae and interspaces the same, but the teeth of the declivity are much coarser the first and fourth of equal size, acute; the second stout, triangular, with acute point at right angles to the third tooth, which is cylindrical, prominent and enlarged towards the apex. The antennal club is slightly oblong, with two sutures on the anterior face; the first straight and the second bisinuate, and posterior face is glabrous, shining, and without sutures. 9 Type.

OF WASHINGTON. 77 This species belongs to the T. pini division of the genus, characterized by four marginal teeth on each side of the elytral declivity. Evidently it was not represented in material seen by Eichhoff and Blandford. It is readily recognized from Tomicus integer Eichh., by its much smaller size, and from T. oregoni Eichh. and other allied North American species, which might find their way into Mexico, by its more slender form. Tomicus cribripennis Eichh. Four females and four males, Mexico, in pine, received from Dr. Bonansea. This species is a representative of the section of the genus characterized by five teeth on the side margin of the elytral declivity, and also with the interspaces of the elytra punctured. This sec- tion is represented in the United States by Tomicus confusus Lee., which I have found to be a common and sometimes destructive enemy of the pinon (P. edulis in Arizona, and P. monophylla in Southern California) ; also by an undescribed species from Idaho and Montana, in Pinus monticola. The Mexican species differs from T. grandicollis Eichh. of the Eastern United States (which also has five teeth on the declivity) in the distinct punctures of the elytral interspaces. Blandford states that the specimens seen by him differ from the type in being smaller and less robust, which is the differ- ence from confusus observed in the specimens before me. Phlceophthorus moripcrda n. sp. Female type, length 1.65 mm.; stout, cylindrical, reddish-brown; head, prothorax and ventral surface darker. Elytra, legs and antennal scape reddish. Head subcorivex, subopaque, finely granulated and with very fine, short, sparse pubescence, and with a fine, median longitudinal elevated line on the slightly flattened and more shining anterior half; eyes oblong, oval, not emarginate; antennal scape with a few long hairs; club large with three triangular segments separated by two impressed slightly oblique sutures. Prothorax one- third broader than long, one-half as long as elytra, slightly narrowed from base to front, the anterior margin not serrate; surface opaque, clothed with reclining, stout, yellow pubescence and roughened by sparsely placed granules, which are coarser towards the sides. Elytra shining, the base elevated and serrate; the side margins serrate from middle to apex; serrations much coarser on the side margins of the declivity; striae impressed; punctures distinct to vertex; inter- spaces faintly elevated and roughened with a row of asperities and each with a row of fine, yellowish hairs from base to apex; declivity convex; striae deep and narrow, but the punctures obscure; interspaces convex, and with a row of small acute granules. Male type, length 1.85 mm.; same form and color as female but with the head narrower and deeply concave, shining; the sides elevated and 78 ENTOMOLOGICAL SOCIETY with an acute tubercle towards the base of the antenna and faint broken transverse ridge across the front between the tubercles; the anterior margin with a small shining apical tubercle; the scape of the antenna distinctly fringed; the granules of the interspaces of the declivity are coarser on the vertex and face. 9 and 3 Types. No. 7515 U. S. Nat. Mus., Irapuato, Mexico, in white mulberry, H. Chambon collector, but received from Prof. Herrera. Three females and two males of the same lot vary in length from 1.65 to 2.1 mm., but otherwise show very little variation from the types. Three specimens were received through Dr. Erwin F. Smith, from Prof. Herrera, who, as stated in his published account, received them from Mr. Hipolite Chambon, with the statement that it had killed more than one thousand small white mul- berry trees in Irapuato, Mexico. This species differs from any of those mentioned by Blandford under Pkloeotribus, but belongs to his division characterized by the club of the antenna, which is not twice as broad as long. This is a character .common to the species of the well denned genus Pkl&opkt! torus which is represented in the United States by P. frontalis and its allies, and in Europe by P. rhododactylus . The Mexican species comes closer to our mulberry bark beetle P. frontalis, but is distinct from it by its smaller size, brown club of the antenna, the prothorax more opaque, smoother, and the elytra more shining. Phloeosinus tacubaya n. sp. Female type, length 2.4 mm.; body stout, piceous, with elytral declivity more reddish; pubescence short, stout, intermixed with scales on declivity. Head with front convex, finely granulated, granules becoming sparser towards middle; with fine carina from middle to anterior margin and finely densely punctured on vertex; eyes oblique, deeply emarginate; antennae missing, but in another speci- men the club is oblong, with first and second sutures on anterior face early straight and the third strongly curved; the sutures are the same on the posterior face, but the first joint is very much shorter. Pro- thorax much broader than long; sides rounded from base to apex, faintly constricted towards anterior margin; surface shining, smooth, rather densely punctured, without dorsal line or space. Elytra twice as long as prothorax, and slightly broader; basal margin serrate, produced for- ward but not elevated; striae narrow, with contiguous elongate punctures; interspaces flat, irregularly rugose; declivity convex; first and third interspaces serrate; second narrow, convex, punctured. Male type, length 2.4 mm.; differs from female in its narrower front, with a faint median impression and in the declivity of the elytra, which is more shining and less pubescent. OF WASHINGTON. 79 $ and cT Types. No. 7516 U. S. Nat. Mus., Tacubaya, D. F., Mexico, in Cupressus, E Baumann collector, February, 1903. One additional male and two females from same lot show no difference except that the front of the males has a much more distinct elevated line from middle to anterior margin. This species and the following belong to the division of the genus characterized by a smooth second interspace of the elytral declivity of the females. The species of this genus infest Juniperus, Cupressus, Chamacyparis, Taxodium, Sequoia, and their allies, and, under certain conditions, may be destruc- tive. Phloeosinus baumanni n. sp. Female type, length 3.5 mm.; body stout; prothorax, ventral surface and legs black, elytra more reddish; pubescence yellowish, short, dense on front of head and prothorax, sparse and in approximate rows on elytra; the declivity clothed with fine, short scales. Head, front convex, rugose, with faint impression and faint, elevated line from margin to vertex, slightly broken by impression ; eyes oblong; antennal club large, oblong, with three oblique broadly curved sutures on anterior face and three nearly transverse curved ones on the posterior face. Prothorax, one-third broader than long, narrowed from base to apex; sides rounded, faintly constricted anteriorly; punctures dense, coarser towards sides. Elytra slightly more than twice as long as prothorax; base subacute, produced forward, slightly elevated and serrate; striae scarcely impressed but with very coarse distinctly sep- arated punctures; the interspaces narrow, scarcely elevated but roughened with rather coarse transverse rugosities which often extends across the striae between the punctures; declivity convex, with inter- ^ spaces one and three strongly elevated and closely serrate, the second interspace nearly flat and densely subrugosely punctured. Male type, length 4. i mm. ; same color and form as female, except that the prothorax is narrower anteriorly; the front is narrow, flat or subconcave, with median elevated line from middle to anterior margin; the elytral interspaces are smoother and the strial punctures more distinct, / the declivity steep, with the first interspace broad, flat, shining and irregularly punctured, with two or three teeth on the vertex; the first stria is distinct, strongly punctured and broadly curved towards the side, almost obscuring the second interspace and stria; the third interspace is prominently elevated and serrate, with coarse, closely placed teeth. 9 and cT Types.

Female type, length 4 mm. ; elongate, cylindrical, dark brown. Head broad, with two frontal elevations sepa- rated by a shallow median groove; anterior and posterior halves punctured ; middle rugose from eyes to frontal elevation; antennal club broad, com- pressed towards tip, and with two broadly curved sutures. Prothorax nearly a." long as broad, slightly narrowed from base to anterior margin, which is sinuate, the base declivous and bisinuate; punctures moderately coarse, becoming finer towards sides; anterior third with distinct trans- verse ridge extending across proepisternum. Elytra twice as long as prothorax; sides parallel; base obliquely serrate; interspaces rough- ened with asperities, which are coarser towards base and vertex; the first interspace with a row of coarser asperities from near base to vertex ; declivity subconvex, sparsely clothed with long erect hairs which also extend to near the middle of the elytra; the striae narrow, punctures obscure; interspaces flattened and roughened with irregular granules. Male type, length 4 mm. ; differs from female in the more prominent tuberculate frontal elevations separated by a deeper groove. Prothorax with transverse ridge across the anterior third less distinct than in the female and not extending across the proepisternum. Elytra with deeper striae and more convex interspaces. $ and cf Types. No. 7518 U. S. Nat. Mus., Sacramento, Amecameca, Mexico, in pine, A. L- Herrera collector. Twenty-five females and eleven males received at different times from A. L Herrera and Dr. S. J. Bonansea, from Ameca- meca, Michoacan and Tacubaya, Mexico, vary in length from 3 mm. to 4 mm. average about 3.8 mm. The characters described in the types are fairly constant in all the specimens, but the submarginal ridge is more distinct in some females than in others, and, while present in some males, it is obscure or absent in others. This species belongs to the division of the genus characterized by more prominent frontal tubercles in the male and a trans- verse ridge near the anterior margin of the prothorax of the female. It finds its nearest ally in D. parallelocollis Chap, of Mexico, and D. frontalis Zimm. of the Eastern and Southern States. It is, however, easily separated from parallelocollis by the uniform smaller size and more brownish color, and is distinct from D. frontalis, with which the smaller examples agree in color and size, by the much longer and coarser hairs of the elytral declivity, the rugosities coarser towards the base and declivity, and a row of coarse granules on the first elytral interspace. This is evidently the species most to blame for the destruction of the pine forests in Mexico, and evidently has habits very similar to that of D. frontalis, which devastated the pine and spruce forests of the Virginias in 1891 and 1892, OF WASHINGTON. 81 as described in Bulletin No. 56, West Virginia Agricultural Experiment Station. Dendroctonus parallelocollis Chap. Ten specimens received from Prof. Herrera, taken from dying pine trees in Michoacan and other localities in Mexico. This is evidently the same as D. approximatus Dietz, which name is more recent, but may be used for the variety found as a common enemy of the pine in Arizona and New Mexico. Specimens of this variety are distinguished from those before me from Mexico only by the much shorter pubescence and hairs on the sides of the pro thorax towards and on the basal angle. All the species of Dendroctonus are exceedingly variable, and when a large series of specimens of -allied forms are examined it is very difficult to separate them by any constant characters. Dendroctonus valens Lee. Four specimens, Michoacan, Mexico in pine, received from Prof. Herrera. These are typical ex- amples of the large red Dendroctonus heretofore identified as D. terebrans Oliv., which latter is a black form restricted to the Eastern and Southern United States, while D. valens is widely distributed over the Eastern as well as the Western United States and is a common enemy of all of the pines, and occasionally found in spruce. It breeds in the living bark at the base of healthy trees or that of stumps of recently felled ones. I have found that a large per cent, of the so-called basal fire wounds of the Western yellow pine is primarily due to the work of this species. Very little evidence has been found, however, of trees having been killed by it. Hylurgops planirostris Chap. One specimen, Mexico City, 1903, in firewood, received from Prof. Herrera, under his number 865. This species was recorded by Blandford from several localities in Mexico and Guatemala. It is, as he says, allied to H. rugipennis Mann., which I have found to be common in Picea, Pinus and occasionally in Abies and Pseudotsuga from Northwestern Washington to the Black Hills of South Dakota, and south to Monterey, California and Williams, Arizona. The Mexican species is easily separated from rugipennis, however, by the obscure punctures and fine rugo- sities of the pro thorax. Blandford included H. planirostris in the genus Hylastes, but it seems to me that Hylurgops is sufficiently characterized by the deeply bilobed third tarsal joint and ether characters to justify retaining it for this and several European and American species. Mr. Schwarz stated that the life-history of the remarkable Mexican Scolytid genus Oiapuisia has been published by 82 ENTOMOLOGICAL SOCIETY Dr. Eugene Duges, and there may be other scattering notes on Mexican Scolytidse. He suggested that the Scolytidae collected at Brownsville, Texas, last summer by Mr. Barber be worked up and incorporated by Dr. Hopkins in his paper, since they were in reality Mexican Scolytid species. Mr. Barber, under the heading of Short Notes and Exhi- bition of Specimens, showed several original photographs of the work of the tube-forming termite (Termes tubiformans) at Brownsville, Texas, and described the termites' work. This species, by covering large areas of grass and herbage with its clay or earthen galleries, destroys and kills much of the pasturage and is thus of considerable economic importance. Each blade, stem or twig is completely incrusted and portions of the ground where these termites are abundant thus presents a very singular appearance. Mr. Brues stated that T. tubiformans is common at Austin, Texas, and that it feeds there upon cow manure. Mr. Fair- child asked Mr. Schwarz whether any truly fungus-cultivating termites were known in this country. Mr. Schwarz replied that he did not know of the habit of fungus-cultivating in any of our species. Mr. Banks showed a small piece of limestone rock in which were many minute holes, each of which was occupied by a mite of the family Oribatidae, genus Scuto vertex. This was one of many spray-covered stones taken from the banks of a stream of water near Ithaca, N. Y. The mite appears to have no special peculiarities, but is a new species and closely related to one found on boulders between tide-marks on the northern Atlantic coast. Inasmuch as each mite, be it large or small, fits its hole, it seems evident that the holes are caused by the mites themselves; yet he could offer no explanation or supposition as to how this is done. Mr. Marlatt then introduced to the Society Mr. K. Nawa, of Gifu, Japan, and expressed for the latter his pleasure at being able to visit Washington and attend a meeting of the Entomological Society. OF WASHINGTON. 83 FEBRUARY 2, 1905. The 1 93d regular meeting was held at the residence of Dr. L- O. Howard, 2026 Hillyer Place, N.W., Vice- President Hopkins in the chair and Messrs. Alwood, Ashmead, Barber, Benton, Burke, Cook, Currie, Doolittle, Dyar, Fairchild, Fiske, Girault, Hinds, Howard, Hunter, Marlatt, Morrill, Morris, Pierce, Quaintance, Schwarz, Scott, Titus, and Webb, members, and Messrs. Beattie, Crawford, Hooker, Norton, Rankin, Sanders, and Sasscer, visitors, present. Dr. Dyar showed a specimen of the larva of Castnia licus Drury which has been received at the Bureau of Entomology as injurious to sugar cane in British Guiana, by boring in the stems. Very little is known about the larvae of the Cast- nidge except that they are borers. This has led some to infer that there is a relationship between them and the boring Hesperiidae such as Megatkymus yuccas, but such should not be the case, as the venation is entirely different in these groups. The larva before us bears out this conclusion, as it is a true Tineoid form, not related to the Butterflies, but to the Cossidae and Sesiidae. LARVA OF CASTNIA LICUS Drury. BY HARRISON G. DYAR. Larva. Head large, rounded, full, somewhat flattened, apex retracted in joint 2; clypeus small, shield-shaped, but with large paraclypeal pieces which touch the vertical membrane; antennae very small, rudimentary, shorter than the palpi; ocelli, nearly obsolete, two small ones seen near the antennae; brownish luteous, darker around the mouth, the mandibles and articulations black. Body robust, cylindrical; thorax enlarged, especially the dorsal parts of joints 3 and 4; joint 5 small, both dorsally and laterally; joints 6 to 10 about equal, 1 1 and 12 a little smaller. Spira- cles large, narrowly elliptical, the one on joint 12 largest and directed obliquely backward. Thoracic feet very short, almost rudimentary, projecting laterally. Abdominal feet on joints 7 to 10 distinctly elevated but without the ordinary hooks. They are covered .with numerous minute spicules, not in rows but in a large patch which narrowly runs across between the feet. These spicules are present also on the ventral side of joints 3 and 4 and dorsally on joints 3 to 11. On joints 7 to 84 ENTOMOLOGICAL SOCIETY 10 dorsally they are placed in an elliptical, slightly raised area divided by a groove, so that the larva may almost be said to have feet on its back. No spines on joint 13. Shields reduced, the cervical shield large, scarcely chitinous except in a number of irregular brown patches; a slight linear thickening of the cuticle on the posterior edges of joints 3 and 4; anal flap large but uncornified. Skin smooth, yellowish white, unmarked. Tubercles very small, setae minute. Arrangement normal for the Tineoidea without secondary hairs of any kind. On the thorax i and ii remotely approximate in pairs, iii very small, iv rather large, v below it, vi single on the leg base; on the abdomen i dorsad to ii, remote, 11 opposite the edge of the spined area, iii above the spiracle, iv and v approximate, superposed on the upper subventral fold, vi posteriorly on the leg base, vii of three setae on the anterior leg base, two of them weak and apparently sometimes absent, viii on the inner side of the leg. The Recording Secretary exhibited for Mr. A. N Caudell a copy of the first volume of Kirby's Synonymic Catalogue of Orthoptera, containing the Forficulidae, Hemimeridae, Blattidae, Mantidae, and Phasmidae, and presented for Mr. Caudell the following notes: KIRBY'S CATALOGUE OF ORTHOPTERA. BY A. N. CAUDELL. Through the kindness of the author I have just received from the British Museum a copy of the first volume of Kirby's Synonymic Catalogue of Orthoptera. This volume contains the families Forficulidae, Hemimeridae, Blattidae, Mantidae, and Phasmidae. The saltatorial families will appear in a second volume. The general arrangement of this catalogue is the same as that of the Neuroptera, Libellulidae, Lepidoptera Heterocera, and Lepidoptera Rhapolocera by the same author. This catalogue forms a volume of over 500 pages, is well printed and well bound and the reputation of the author as an orthop- terist is a guarantee of the excellency of the contents. How- ever, as is invariably the case of any undertaking of considerable magnitude, there are certain omissions and errors that have crept in. I now desire to correct a few points that I believe to be erroneous, note a few omissions known to me, as well as to offer criticisms on a few points in which I am unable to agree with the author. With one or two exceptions the OF WASHINGTON. 85 following remarks apply only to genera or species found in our own country. Labidura riparia Pall. The habitat of this species should include localities in the new world. The variety erythroce- pkala, however, is recorded from the West Indies and the author may refer all the new world specimens to that form. Anisolabis annulipes Luc. A. bormansi Scudd., azteca Dohrn and probably also antennata Kirby should have been quoted as synonyms of this species. Bormans placed antennata as synonymous with azteca, bormansi was established as synony- mous with annulipes by McNeill, and I have shown azteca and bormansi to be synonymous. However these are opinions and each worker is at liberty to follow his own belief. Sphingolabis taeniata Dohrn. S". linearis Eschscholtz is quite certainly the same as this and has priority by some years and should take precedence. Ischnoptera uhleriana Sauss. /. unicolor and lithophila of Scudder are both synonyms of uhleriana, so admitted by their describer. Temnopteryx mrginica Sauss. This is listed as distinct though it has been proved by breeding that it is the female of Ischnoptera uhleriana. Phyllodromia Serv. Though Mr. Kirby knew this to be preoccupied he still uses it as valid, citing Blattella and Liosil- pha as synonyms . This is done, however, as he wrote me, because of lack of time to determine whether Liosilpha or Blattella should be used in the place of it. The probability is that they may both be retained, depending upon whether or not germanica and pumicata, their respective types, are congeneric. Phyllodromia germanica Linn. Blatta obliquata Dold. and Ischnoptera bimttata Thorn, should be placed as synonyms of this species. Instead, the former is omitted altogether and the latter is listed as a distinct species. Phyllodromia bimttata Serv. I very much doubt the dis- tinctness of this species. It is certainly no more than a variety of germanica. Phyllodromia borealis Sauss. This is, according to Blatchley, the female of Isch. pennsylvanica Deg. Temnopteryx marginata Scudd. This species, which is also a synonym of I. pennsylvanica, is omitted from the cata- logue. Temnopteryx major Sauss. This belongs to the genus Ischnoptera. Loboptera americana Scudd. The original reference is wrongly given, the correct citation being Proc. Davenp. Acad. Nat. Sc., viii, p. 93, pi. ii, fig. 4 (1899). S(J ENTOMOLOGICAL SOCIETY Pelmatosilpha floridana Walk. Under this species, or at least in the same genus, should come the Platyzosteira sabali- ana of Scudder, which Kirby locates in the genus Eurycotis as a synonym of Walker's semipicta. Having the types of both floridana and semipicta he should be able to properly place them, but Mr. Kirby is surely wrong in generically sepa- rating their supposed synonyms ingens and sabaliana, which are certainly congeneric if not synonymous.* Tenodera sinensis Linn. This should have North America included in the habitat. It is the type of the newly established genus Paratenodera. Mantis religiosa Linn. Like the above this should have North America included in the habitat. Stagmomantis Carolina Linn. S. ferox Sauss., dimidiata Sauss., wheeleri Thorn., and tolteca Sauss. should be placed as synonyms of Carolina. Oligonyx scudderi Sauss. O. bollianus S- & Z., and Mantis miss our iensis Glover are synonyms of this species. Instead the former is listed as distinct and the latter is omitted from the catalogue. Thesprotia graminis Scudd. This is certainly not congeneric with Oligonyx scudderi, though here placed in the same genus with it. Pseudosermyle Caud. Though I especially mentioned P. banksi as the type when I established this genus Mr. Kirby gives arbuscula as the type. Timema Scudd. This remarkable genus is certainly worthy of subfamily distinction, but Mr. Kirby includes it in the Anisomorphinae, making no reference to Timeminae, the sub- family proposed for it. Aplopus Gray. Kirby uses the amended spelling Haplopus and gives jamaicensis as the type. But the genus is mono typi- cal, micropterus being the only species included under it at the time of its establishment. Therefore, micropterus and not jamaicensis is the type. Mr. Kirby retains certain species as valid that I should consider as invalidated through preoccupation. Such, as an example, is Phoraspis cossidea Daltn., 1823, described as Blatta cossidea and, in my opinion, is preoccupied by Monastria cossidea Esch.. 1822, also described in the genus Blatta.

OF WASHINGTON. 101 PLATE II. NEW AMERICAN SPIDERS. 102 ENTOMOLOGICAL SOCIETY Mr. Schwarz exhibited a box of Theodosia JHelionica) beetles from Mount Kina-Balu, North Borneo, and spoke on the genus and on the characters used for the distinction of species. The genus is one of the few Cetoniid genera that are armed in the male with one cephalic and one thoracic horn, thus resembling the well known genus Dynastes of another sub- family of the Scarabaeidse, viz, the Dynastinae. With the exception of a single species the genus is peculiar to Borneo, and up to quite a recent date specimens were extremely rare in collections. Last year Messrs. Goss and Dodge donated to the National Museum a fine collection of Mount Kina-Balu insects, among which were no less than 359 male specimens of these Theodosia beetles. Mr. Schwarz finds that the most elementary and most readily observable character, viz, the sculpture of the upper side, is absolutely safe to separate one of the species, T. westwoodii, from the rest. There were 266 specimens of this species, which is always recognizable from the double punctuation of the thorax (smaller and larger punctures intermixed) and from the peculiar punctuation of the elytra (the punctures being imperfect and umbilicate, i. e., there is a semicircle open behind), and with a small punc- ture in the center. The horns of this species show an enormous extent of variation as to length and curvature, but the cephalic horn is always simple, i. e., not bifurcate. The second series of species is always characterized by uniformly dense granula- tion of the thorax and by the elytra not having any punctures at the surface. The substance of the elytra is transparent and the peculiar sculpture can easily be seen within the elytra, although the punctures do not reach the surface. Several species have been made of this set, and it is worth while to record the differences. T. magnified Rothschild, represented by 69 specimens, has the cephalic horn simple; T. telifera Bates has, on the other hand, the cephalic horn bifid, but there is not the slightest other difference between the two forms, so that when, as frequently happens, the cephalic horns get broken off, the two forms cannot be distinguished. To make the matter more interesting, each of these two forms has a companion form distinguished at the first glance by a dense OF WASHINGTON. 103 fringe of yellow hair along the inner margin of the front tibia. Thus, Theodosia perakensis Moser has the cephalic horn simple, but the anterior tibia fimbriate, and T. rothschildi Janson has the cephalic horn bifid and the anterior tibia fimbriate. There are, again, no other differences to distinguish these forms, and it may be seriously questioned whether these four forms may be considered as distinct species. It may be added that dissections of all forms of Mount Kina-Balu Theodosias proved that the male parts are absolutely identical. Mr. Schwarz showed also the females, some 53 in number. Among these only one, or at most two, forms can be distinguished. Dr. Dyar stated that the Lepidoptera from Mount Kina-Balu in the Goss and Dodge collection make a very fine showing. He experienced great difficulty in getting names for all the species, however, since Whitehead's work on the results of the explorations in Mount Kina-Balu lists only the new or rare species that were taken and is, therefore, of no assistance in determining the others. Mr. Schwarz said that it is a common fault with writers of works on exploration that complete lists of the species collected are not given, only those species either new or rare being listed. Mr. Norton, upon the invitation of Dr. Howard, told of certain experimental work on dimorphism that is to be under- taken by Dr. C. B. Davenport under the auspices of the Carne- gie Institution, at the Biological Station at Cold Spring Harbor, Long Island, N. Y. He stated that Prof. W. E. Castle has established, in the guinea pig, an experimental form of di- morphism which follows Mendel's Law, while he himself has found the same law to hold as regards certain plants upon which he has been experimenting. What is now to be investigated is, whether dimorphism in plants and animls, as occurring in nature, follows this law. An interesting object of experimentation is the common yellow swallow-tail butter- fly (Papilio turnus), in which, in localities where the species is double-brooded, there are two forms in the female, one black and the other yellow. Extensive breeding experiments are to be undertaken to determine, if possible, whether the 104 ENTOMOLOGICAL SOCIETY production of these two forms follows Mendel's Law and also to ascertain which form constitutes the dominant type in the species. As all the males are ostensibly yellow, the problem is a difficult one, since, if this law holds with this species, some of the yellow males must be potentially black and produce offspring in which the black type prevails. Mr. Cook said he did not believe that dimorphism in nature follows the working of any law. The matter was further discussed by the members present. MARCH 2, 1905. The 1 94th regular meeting was held at the residence of Messrs. A. L- Quaintance and W. M. Scott, 1809 24th St., N.W., President Banks in the chair and Mersrs. Ashmead, Burke, Gill, Girault, Hinds, Hopkins, Howard, Pratt, Quain- ta;ice, Scott, and Webb, members, and Messrs. Davis, John- son, Strauss, and McClendon, visitors, present. In the absence of the secretary Mr. Pratt was appointed secretary pro tern. Prof. Thomas B. Symons, Entomologist of the Maryland Agric. College Exp. Station was elected an active member. The acting secretary read a letter from Prof. J. B. Smith rela- tive to a National Association of Entomologists; this was discussed by Messrs. Ashmead, Banks, Gill, Hopkins and Quaintance. The matter was referred to the following com- mittee appointed by the President at the request of the Society, Messrs. Ashmead, Titus and Quaintance. Mr. Webb exhibited specimens of two species of Desmocerus and presented the following paper: DESCRIPTION OF A NEW SPECIES OF DESMOCERUS WITH A SYNOPTIC TABLE OF THE GENUS. ~: BY J. L. WEBB. Desmocerus piperi n. sp. 9 Length 20.5 mm. Head, pro thorax, ventral surface, legs, and antennae bluish black; elytra bluish green, with narrow orange margins. Body elongate; *-head scarcely as long as pro thorax, narrowed towards base ; pro thorax narrower than elytra, and strongly narrowed towards head, with an OF WASHINGTON. 105 obtuse elevation midway on each side, basal angles produced into spines; elytra scarcely narrowed posteriorly, posterior margin rounded with apices sub-acute. d\ Length 18.8 mm. Elytra distinctly narrowed poste- riorly, and uniformly dull orange colored in pinned specimens (bright orange-red when living). $ and c? type No. 8401, U. S. N. M. ; c? Blue Mts., Wash., July, 1896. Collector, C. V. Piper. The specimens before me, 15 in number, show little variation from the type, except one male, in which the fifth joint of each antenna is deformed. Collected in numbers by Professor C. V. Piper, in the Blue Mountains of Oregon, and the Bitter Root Mountains of Idaho, feeding on the flowers of the black-berried elder, Sambucus melanocarpa. The following table will aid in the identification of the species of this genus: I. Elytra with basal third orange -colored, posterior two- thirds blue, without orange margins. Sexes equal in size and of the same color. Elytra of & not distinctly narrowed towards apex palliatus. II. Elytra with orange margins in one or both sexes; males smaller, with elytra distinctly narrowed towards apex. A. Elytra with narrow orange margins in both sexes. L a.

Female elytra with narrow orange margins . . .piperi. b. Female elytra with broad orange margins, darker only on median dorsal surface auripennis. Mr. Pratt exhibited slides and figures of larvae, pupae and adults of Ceratopogon guttipennis Coq. which he had found in the mountains at Bluemont and Woodstock, Virginia. The larvae were found living in hollow tree stumps filled with water, in company with larvae of three species of mosquitoes; Culex triseriatus, C. signifer, and Anopheles barberi. Their food seemed to be the rotting leaves, dead insects and other debris. He stated that the little "gnats," or. as they are locally called "punkies" or "no-see-ums," were exceedingly troublesome, especially early in the morning. Mr. Burke asked if any species of Ceratopogon occurred on the Pacific coast and M 106 ENTOMOLOGICAL SOCIETY Pratt replied that he had seen specimens from California and there was no reason why other species should not exist on the coast further north. Dr. Hopkins stated that he had had some experience in West Virginia and Maine with these insects and they were exceedingly troublesome. Dr. Hopkins exhibited specimens of fossil mesquite wood from Texas Hill, Arizona, showing distinct fossilized borings, apparently of a Cerambycid larva; and some fragments of petrified wood from the same locality showing insect borings filled with perfectly preserved egg-like objects. Dr. Hopkins made a few remarks on the Scolytid larvae and their mouth-parts. He stated that he had found very constant characters in the larva which greatly simplified the classification of several groups. A box of pinned larvae was exhibited, and several plates of drawings were also shown. Dr. Gill asked if the larval hooks mentioned by Dr. Hopkins were co-ordinate with any character in the adult. Dr. Hop- kins replied th^t so far as he could determine they were not. Mr. Banks presented the following paper: NEW TRICHOPTERA FROM JAPAN. BY NATHAN BANKS. Some time ago Mr. S. I. Kuwana sent me a small collection of caddice-flies from Japan. I was at work on them when Mr. Nawa reached Washington bringing some more species. The following paper is based on these two collections. They con- tain 25 species, 9 of which have been described, 12 of which I describe herewith, and four are represented by females not sufficiently characteristic to be described. Two of the described species have only just been published by Dr. Ulmer, and I had them in manuscript. Three new genera are described, all in the L/imnephilidae. None of the species are European, but one was described from Eastern Siberia. Doubtless collections from the northern parts of Japan will show some European species. * Too few species are as yet known to make any generaliza- tions regarding the trichopterous fauna of Japan. There are several remarkable genera present, most noteworthy is Peris- soneura which has a series of costal cross veins. It may be also mentioned that the largest caddice-fly known is from Japan, Holostomis regina, a magnificent insect. OF WASHINGTON. 107 Phryganea latipennis n. sp.

Venation as usual in genus. Expanse 22 mm. Two specimens from Hikosan, Buzen, Japan, 28 March. Gcera japonica n. sp. Similar in size and general structure to G. pilosa, but paler yellow throughout; the swollen area in the front wings at end of the "area interclavialis " is not near as large as in G. pilosa; the fork of front wings OF WASHINGTON. 109 extends fully to middle of discal cell (on outer third in G. pilosa); fork 3 has a shorter pedicel than in that species. The comb on venter of male has five teeth each side, and the middle one is not much longer than the others; the male genitalia also differ. Expanse 18 mm. Two males from Kawana, Japan, 25 June. Crunoecia albicornis n. sp. Head black, with tufts of long black hair above eyes; antennae black, on basal joint with long erect black hair all around, beyond this joint the antennae are nearly white, the first few joints marked with black; palpi pale brown; thorax black, with some tufts of black hair in front; abdomen dark brown; legs pale brown, almost white on tarsi; wings blackish, with long black hairs, and short, yellowish appressed hairs, fringe blackish, with two or three white patches on outer part, hind wings blackish, with some short yellowish hair, fringe long, some white spaces in it between ends of veins.

Wings with forks i, 2, 3, 5; discal cell longer than the pedicel, but fork i extends only a little way on it, fork 3 reaches anastomosis, but not farther, the cross-vein connecting cubital and anal is before middle of discal cell; in both wings the cross- vein at base of the fourth apical cell is hyaline white. Expanse 20 mm. Two specimens from Hikosan, Buzen, Japan, 28 April. Perissoneura similis n. sp. Jet black; front and middle legs nearly white, hind pair darker; male with a large white spot in each wing beyond the anastomosis, elongate and bent outwards, the inner side distinct, but outer edge ragged and fading out, the one in fore wing has the inner side angulate, the one in hind wings has the upper part of inner side concave ; female with wings entirely black, except faint small whitish spot in base of second and fourth apical cells, and on the thyridium, in the hind wing a small spot in base of fourth apical cell. Wings shaped about as figured for P. para- doxa McLach. or a trifle more elongate; the costal cross- veinlets are present, but the discal cell is longer, the apical cells rather shorter, the anastomosis more regular, and fork 4 is absent in both sexes. Expanse, d\ 46 mm., 9 5 mm. Two males and one female, from Hikosan, Buzen, 29 May, and Tsuno, Buzen, Japan, 8 May. Perissoneura japonica n. sp. Similar in most respects to P. similis, it differs in shorter and more rounded wings, the white spots of male are broader, not so elongate, 110 ENTOMOLOGICAL SOCIETY placed a little nearer the tip, and with the outer margin as sharp and distinct as the inner edge, the inner side of the mark in both wings is slightly concave; the general color of the wing is more of a deep brown than a black, and is rather shining. The species is also smaller than P. similis. The genitalia show differences as figured. Expanse, cT, 38 mm., $ , 44 mm. One pair from Gifu, Japan. This is probably the species figured by Dr. Ulmer as the male of P. paradoxa, which was described from a female. However, McLachlan says that fork 4 is present in forewings and so figures it, while in this and P. similis fork 4 is absent in both sexes. Dr. Ulmer says nothing about this matter. Moreover the anastomosis of P. paradoxa, as figured, is very much more irregular than in either of my species. Therefore, I believe that P. paradoxa is unknown to Dr. Ulmer and myself, and that there are at least three species of Perissoneura in Japan, if indeed my two species do not form another genus on account of the absence of fork 4. Odontocerum japonicum n. sp. Black; wings brown, anterior pair rather darker than hind pair, and darkest in the apical third; legs brown, tibiae and tarsi paler. Differs at once from the European O. albicorne in that the discal cell of fore wings is extremely long, fully five times as long as its pedicel, the first apical cell not reaching back on the discal cell more than one-fifth its length; the fifth apical cell has a pedicel rather longer than in O. albicorne, and the third apical cell is also acute at base, and short pedicellate. The antennae are barely dentate. Expanse 34 mm. Two specimens from Gifu, Japan. Molanna mopsta n. sp. Brown; wings dusky, with some black, and more yellowish appressed hair, blackish on apical margin, and extending somewhat up on the veins; hind wings paler, the costal area rather yellowish, fringe of anal region very long, gray, especially long on the basal lobe; legs yellowish, with yellowish spurs, and some fine black spines on underside of the tibiae and tarsi. In fore wings the median vein beyond the anastomosis has three branches; the first apical cell is swollen above near tip. Vena- tion of hind wing of male as figured. Expanse 27 mm. One male from Gifu, Japan. A black-winged female Molanna, also from Gifu, probably represents another species, as it is smaller. OF WASHINGTON. Ill Arcto psyche japonica n. sp.

Although Provancher in 1883 refers to the cT of Magachile brevis there are no specimens in the material sent me. Since the c? of this species is so readily separated from others closely related, by the shape of the antennae it is likely that the reference is to another species. 1888: Add. Fauna Ent. Can.

I have examined Cresson's type specimen, Provancher's type of the genus, and specimens of Ashmead' s genus Melanostelis. The Cockerell species placed in this genus do not belong here as can be readily seen by an examination of the descrip- tions, which show that they are not Stelidinae.

In three earlier papers on this genus, published in the Proceedings of our Society, 1 the writer has treated as many groups. There remain to be reviewed several more or less pecfeetly denned groups and a number of isolated species and other forms which do not possess easily discernible characters indicative of their position in a natural arrangement of the entire series. In the present paper the simplest forms, based on the structure of the tarsal joints, will be considered first, and those forms in which the third joint of the anterior and sometimes median tarsi are widest will be discussed later. Some questions of nomenclature will be taken up, as economic workers frequently inquire in regard to these matters, and it is preferable to have these questions considered in a technical paper. Sphenophorus marinus, new species. Of similar form to incequalis; smaller and less robust; surface opaque black, with antennae, tarsi, and lateral margin of the elytra piceous. Rostrum two-thirds as long as thorax, stout, moderately arcuate, strongly punctate in basal three-fourths, especially coarse at the base, and finely sparsely punctate at apex, which is very slightly dilated but compressed and prolonged posteriorly into an acute point, strpngly dilated over scrobes but scarcely more compressed than at apex. Head strongly but somewhat sparsely punctate. Eyes with a fine reflexed posterior margin, separated from the head by a strongly impressed wide extra- orbital line. Thorax longer than wide by about the shortest diameter of the apical constriction ; posterior two-thirds with sides nearly parallel ; base strongly arcuate. Surface very coarsely, moderately, deeply and very densely to confluently punctate, leaving a distinct but irregular elevated median line, not quite attaining either apex or base and occasionally slightly interrupted; a few punctures coalescing near sides posteriorly, forming J See Volume xn, p. 50, 1905. OF WASHINGTON. 167 a shallow fossa .each side. Scutellum large subtriangular, concave at base, rounded at apex, nearly one-half longer than wide. Elytra moderately acuminate; striae moderately fine, deep, especially at base, with punctures much wider basally and not wider at apex. Inter- vals flat, subequal except third which is a little the widest, punctures large and placed at very irregular intervals except on first where they are smaller and twice as closely placed. Humeral and subapical callosities of moderate size, shining black and finely punctate, the latter prominent. Pygidium coarsely and deeply punctate. Lower surface strongly and coarsely punctate, sparsely on metathorax and first abdominal segment. Legs finely punctate; tibiae weakly sinuate on inner border, finely fimbriate, obliquely truncate at apices. cT. Pygidium wide and subtruncate at apex, with fringe of yellow hairs nearly uniform; ventral concavity distinct, shallow. 9 . Pygidium narrow and rounded at apex, with hair normally in tufts at sides; first and second abdominal segments connate at middle, where the punctures are very sparse. Length 4.8-6.0 mm.; width 1.9-2.4 mm. Sea Isle City, N. J., June 10; Westville, N. J., collected by Mr. Charles R. Boerner, to whom we are indebted for this well-marked and interesting species. It is evidently maritime and probably very local. Type. No. 9449, U. S. National Museum. Cotypes in Mr. Boerner 's collection. This species is the smallest Sphenophorus occuring in the United States. The tarsal and tibial structure is similar to parvulus and minimus, which also have the same extraorbital grooves. The coarse subconfluent thoracic sculpture alone is quite sufficient for the separation of this species. The elevated median line of the thorax, the large concave scutellum, and prominent subapical callosities are also important characters. The three species which have been mentioned are related to the venatus group. They may be classified as follows: Thorax and elytra of about equal width. Surface with fine cinereous coating of argillaceous material; thorax densely, regularly reticulately punctate, median line absent or very thin. N. Y. 111., Fla. Tex par-vulus Gyll. Surface with velvety brown coating; thorax sparsely, irregularly and coarsely punctate, median line absent or short. W. Pa. 111., Fla. ' "^ Tex minimus Hart Thorax distinctly narrower than the elytra. Black without coating; thorax densely to confluently and very irregu- larly deeply punctate, median line long and broad. N. J. (coast), marinus n. sp. 168 ENTOMOLOGICAL SOCIETY Sphenophorus graminis, new species. Black, moderately shining without coating, of robust appearance due to the elytra being much wider than the thorax. Rostrum less than two-thirds as long as the thorax, robust, moderately arcuate, much compressed, most strongly at the apex; base moderately wide, suddenly and strongly dilated over the scrobes with dilated portion angular, very feebly or scarcely conaliculate ; interocular fossa round, shallow, sometimes indistinct; impressed line more or less indistinct, scarcely longer than the width of the rostrum over the scrobes; apex with a shallow concave triangular space on anterior face, subacutely rectangular on posterior face; surface finely moderately and densely punctate, gradually coarser in basal half. Head feebly, very sparsely punctulate. Thorax (without apical constriction) nearly as wide as long, apical half arcuate, apical constriction strong; base distinctly bisinuate; surface somewhat densely and finely punctate, punctures nearly uniform except along the median line where there is a small narrow smooth space of varying extent (sometimes nearly absent) and at the middle of the basal margin where they are a little coarser and denser. Scutellum feebly concave or nearly flat. Elytra about one-third wider than thorax and scarcely one-fourth longer than wide, moderately narrowed at apex; striae finely uniformly punctate, punctures not visible on the surface, sutural stria strongly curved outwardly at base; intervals flat, alternate in width, narrower ones finely uniseriately punctate, wider ones with two or three rows of similar punctures, antepenultimate interval depressed more or less strongly. Pygidium finely moderately densely punctate, each puncture with a short pale yellowish gray seta, apical tufts wholly wanting or exceedingly minute. Lower surface finely, nearly uniformly punctate, punctures shallow and more dense than on thorax. Legs more sparsely and finely punctate than on thorax; tibiae feebly sinuate on inner surface and sparsely fim- briate; anterior tibiae with outer angle considerably prolonged. Anterior tarsi with third joint less than one-third wider than first. <3\ Ventral concavity broad and shallow. 9 .First and second abdominal segments connate or subconnate at middle.

OF WASHINGTON. 169 The Wyoming and Utah specimens agree in having the abdomen proportionately narrower and the median smooth thoracic line and the apical tufts of the pygidium more dis- tinct. This species is very generally labeled ' ' vomerinus " to which it is related. Sphenophorus subopacus, new species. Of nearly the same form as vomerinus, still duller black, punctuation finer ard deeper and nearly uniform throughout. Rostrum less than half as .ong as thorax, narrow. Thorax very nearly uniformly punctate except r.ear base, where it is more densely subrugosely punctate; smooth space very small, extending posteriorly from a point just in front of the middle. Scutellum not deeply sulcate. Elytra at base strongly sinuate and finely marginate, disk somewhat unequal; striae very narrow, punctures indistinct, first and third striae approximating at base; intervals flat, punctuation practically uniform, punctures same size as those of stria;; intervals i, 3 and 5 wider than 4 and 6, i with four rows of puictures at base, 3 beyond, 3 and 5 with three rows of fine punctures, 2 and 4 with from one to three rows. The second and third intervals from the margin are strongly depressed as in graminis. Anterior tibiae less dilated and not so prolonged laterally. In other respects there is so nearly an agreement of the type with vomerinus that a more elaborate definition is unnesessary, especially so in the absence of better material. Length 9.5 mm., width 3.8 mm. California (Ulke) two females. Type. In the Carnegie Museum at Pittsburg, Pa., co- type No. 8967, U. S. National Museum. Sphenophorus monterensis, new species. Of very similar appearance to graminis, with the same shaped rostrum. Black, shining on ventral surface, opaque on dorsal. Rostrum half as long as thorax, with distinct rounded interocular fossa and feebly indicated, wide, shallow sulcus; otherwise as in graminis. Thorax two-thirds as wide as long, basal two-thirds subparallel, basal margin slightly bisinuate, apical constriction strong, surface somewhat densely and nearly uniformly finely punctate; a distinct smooth inpunc- tate median line about as long as the width of the thorax and with extremities as near the apex as the base. Scutellum feebly concave. Elytra about one-fourth wider than thorax; striae fine, somewhat feebly punctate, sutural stria moderately curved at base; intervals (except third, which is slightly elevated near base) flat, alternate in width, narrow ones irregularly uniseriately punctate, wider ones irregularly triseriately. Pygidium finely densely punctate, with pale yellowish apical tufts. Lower surface finely sparsely punctate, more coarsely and sparsely on metasternum and last ventral segment. Legs polished, finely and sparsely 170 ENTOMOLOGICAL SOCIETY punctate; tibiae feebly sinuate on inner surface, moderately fimbriate, anterior tibiae with outer angle acutely or moderately produced; anterior tarsi with third joint widely dilated, more than one-third wider than first joint. cT- Ventral concavity moderately deep, especially deep in metasternum. Pygidium scarcely subtruncate, sides broadly rounded. 9 . First and second ventral segments with fine dividing line. Pygi- dium with concave area each side with strong median dividing line.

National Museum. The very close resemblance of this species to graminis is remarkable, considering the difference in the tarsal structure. There is a tendency toward a second row of punctures on the narrower elytral intervals and the outer angle of the anterior tibiae is of variable length In one individual the legs are dark rufous. There is considerable variation also in the width of the third joint of the anterior tarsi, but these and other variations from the type ate perhaps individual, although the presence, of a larger series with definite localities may show that there are two species included under this name. As to habits, the only available data are that it was collected by Mr. Schwarz associated with 5. oclireus in wet ground on the banks of irrigating ditches, on the roots of a rush of unknown species. Sphenophorus diversus, new species. Slender, black, with antennae, portions of legs, apex of abdomen at sides, and margins of elytra, piceous. Rostrum less than half as long as thorax, moderately arcuate and compressed, more strongly at apex than at base; apex flat on anterior face, rectangular on posterior aspect; at base fully twice as wide as at middle, strongly dilated above scrobes with acute angles; interocular fossa round and deep; scarcely canaliculate, and with impressed line faint, very short, about twice as long as the diameter of the interocular fossa. Surface coarsely but sparsely punctate, gradually becoming finer to the apex. Thorax fully one-third as long as wide; apical constriction moderate; sides' moderately arcuate. Vittae somewhat distinctly indicated by smoother, more finely and sparsely punctate areas, elevated in their posterior half; median extending from base to apical constriction, nar- rowed at each end to about half the width of the scutellum, widely and somewhat suddenly dilated at a point behind the middle, and becoming confluent with the lateral vittae Justin front of the middle. Interspaces OF WASHINGTON. 171 in the form of two rows of six or more punctures gradually increasing in size to apical constriction, in posterior half with large, irregularly placed, and confluent, foveate punctures.

In its thoracic sculpture this species bears some likeness 172 ENTOMOLOGICAL SOCIETY to ulkei, but the punctuation of the elytral striae, as well as that of the intervals, is without a parallel in our representatives of the genus; in short, the species does not display any great affinity to any others known to the writer. Sphenophorus nevadensis, new species. Form similar to vomerinus, more depressed, shining black.

This form might readily pass as the male of arizonensis, of which I have seen only the female, but for the spongy pubescent lower surface of the third joint of the anterior tarsi which throws the species into a distinct group. The characters furnished in the description indicate the main differences. Otherwise the two are remarkably alike. Sphenophorus subulatus, new species. Form slender, resembling simplex; general color polished black; an- tennae piceous, and portions of legs more or less indistinctly piceous, dorsal surface sometimes piceous. Rostrum three-fifths to four-fifths as long as thorax, somewhat feebly and uniformly arcuate, cylindrical, a little more compressed at base and narrowed at apex; apical fifth to third laterally subcarinate. Base somewhat feebly dilated, little more over scrobes, not canaliculate; interocular fossa inconspicuous, rounded; impressed line wanting or feebly indicated each side of scrobes, not extending to the fossa. Apex flat or slightly "con vex on anterior face. Thorax about one-fourth longer than wide, nearly uniformly arcuate at sides to apical fourth, where it suddenly narrows to apex, the latter strongly constricted ; surface more coarsely, sparsely, and deeply punctate than in simplex, with median smooth line half as long as thorax, extending from in front of middle and not attaining base; each side of median line the punctures are deeper and confluent. Basal margin nearly straight. Scutellum flat or channeled at middle. Elytra one-fourth wider than thorax, one-half longer than wide, some- what strongly narrowed to apex. Striae half to nearly as wide as narrow intervals, coarsely and closely punctate, punctures encroaching on inter- vals gradually more strongly from sutural to lateral, where the striae tend toward obsolescence. Intervals all convex, subequal except third, which is widest, alternately uniseriately and biseriately punctulate, 5] and 7 sometimes uniseriately. Pygidium coarsely and densely punctate, punctures becoming confluent at apex and at sides, glabrous except apical tufts at sides. Lower surface coarsely and densely punctate, punctures deep, not varying conspicuously in size, except in the customary extreme places, 174 ENTOMOLOGICAL SOCIETY those of sides being considerably larger than the middle on the third and fourth ventral segments. Legs strongly and somewhat finely punc- tate. Tibiae densely fimbriate with short hairs. Third joint tarsi: anterior one-fourth, middle and posterior one-fifth, wider than first. 6 71 . Ventral concavity somewhat faint, last ventral segment with large deep rounded fossa. Pygidium comparatively wide at apex, with sides somewhat broadly rounded. 9 . Metasternum flat or nearly so, abdominal segments convex, the last narrowly transversely concave at the apex. Pygidium narrower at the apex and more broadly rounded than in cT. Length 8-9 mm., width 3.9 mm New Mexico, 2 cT d\ i ? (coll. Ulke). One male of this small series is much more finely punctate over the entire surface than the other two, otherwise it does not differ. Type. In the Carnegie Museum, Pittsburg, Pa. Cotype, No. 8970, U. S. National Museum (o 71 ) through the courtesy of Dr. W. J. Holland. This species is very different from any other Sphenophorus occuring in the United States, but three closely related forms in the National collection, from Mexico, display great similarity, evidence that the type may be a common one in Central America and that there may be many more species of this group in that region. The rostrum is more slender than in others of our fauna, while the anterior tibiae are less dilated at the sides than in the simplex and vomerinus groups, and are very slightly angulate. Sphenophorus destructor, new species. Of similar form to zece, proportions variable, but with an average width of four-tenths the length. Surface usually so thickly coated with dull clay-colored or pale brown argillaceous deposit that the punctuation, more especially of the elytra, is much obscured. Rostrum three-fourths as long as thorax, moderately arcuate, nearly straight on middle half of anterior margin, feebly compressed in the middle third, thence widening gradually to the apex, which is subob- tusely angled behind. It is slightly protuberant above the eyes, con- siderably dilated in front of the scrobes, and somewhat deeply and broadly channeled from the base to a little beyond the scrobes, this channel fre- quently filled with argillaceous deposit; surface rather deeply and densely punctate, at base coarsely. Head moderately finely and sparsely punc- tate. Thorax a little longer than wide, posterior half with sides nearly parallel, anterior half strongly arcuate, moderately constricted at apex, strongly bisinuate at base; surface irregularly trivittate; vittae variable, tending toward obliteration in some individuals, middle vitta irregular elongate fusiform, with an irregular, interrupted, shining, black, elevated line OF WASHINGTON. 175 extending from apex to near base, sometimes only half as long, rarely but slightly indicated; lateral vittae sinuate, narrower than median, their most elevated portion showing in a very irregular much interrupted shining black line ; surface of vittae very coarsely, irregularly, rather sparsely, punctate, intervals still more coarsely sparsely punctate; a large shallow fossa each side of the apical half of the thorax and a simi- lar deeper fossa each side of the base. There is usually an indistinct branch of the lateral vittse. Scutellum opaque or subopaque, channeled. Elytral surface comparatively even, with obscure punctuation. Striae moderately, deeply, coarsely and remotely punctate, about 12 punctures on the sutural and next three striae, so closely placed as to form at the base four small shallow fossae between alternate intervals; intervals very irregular owing to the large elytral punctures, alternately very slightly elevated, elevated intervals closely uniseriately punctulate, the others half as closely punctulate, the third with a tendency to produce 2 rows of fine punctures. Pygidium rather coarsely, deeply and sparsely punctate, with short golden yellow hairs and short lateral apical tufts. Lower surface very coarsely, sparsely punctate, at the sides scarcely different from the middle and the lower surface of the thorax; second, third and fourth ventral more finely, apex of last segment densely and coarsely punctate. Anterior tibiae with inner apical tooth moderately long, subapical less than half as long and obtuse. Third joint of tarsi: anterior and middle about one-fourth or one-fifth wider than the first joint, of posterior tarsi scarcely wider. cT. Pygidium subquadrate. Ventral concavity broad and very shallow. 9. Pygidium distinctly narrowed to rounded apex. Metasternum, first and second abdominal segments flat, the last two connate or nearly so.

At first sight this species might be taken for an aberrant form of zecz,- and this applies particularly to large individuals, but it is more nearly related to callosus, and occupies a position about midway between these two as regards the thoracic pattern. A somewhat striking character is the distinctness of the four thoracic and six basal elytral fossae in clean well- marked individuals and the coarsely punctate elevated lines of the vittse. The smallest individuals seen, e. g., the eastern ones, are less strongly marked than the typical Texas and Kansas examples, approaching callosus in the sculpture of the thorax but differing by being proportionately stouter. This species has been reported as quite injurious to corn 176 ENTOMOLOGICAL SOCIETY in portions of Missouri from 1884 to 1903, and to chufa (Cyperus esculentus) in Oklahoma. Sphenophorus sublaevis, new species. Very .similar to the above but distinguishable by its uniform dull black color due to the absence of argillaceous coating and by having much deeper, coarsely foveate punctures on the entire dorsal surface. The rostrum is more protuberant in front of the eyes, more strongly compressed, and the apex is acutely or subacutely angled posteriorly. The elevated portions of the thoracic vittae are much wider, without elevated lines. The four fossae are scarcely indicated. The elytral surface is much more irregular and the very deep and large strial punctures and more minute punctures of the intervals are conspicuous. The apical tibial spurs are very long as are the subapical spurs, the latter being nearly as thick and half as long in the anterior pair. Pygidium with much paler, scarcely yellow hairs. Sexual characters about as in destructor. Length 9-10 mm., width 3.5-4.2 mm. Indiana and Wisconsin (Wickham) ; St. Louis, Mo., July 10, 1873 (C.V. Riley); Champaign, 111., April 23; Cook Co. Ills.

Sphenophorus sculptilis Horn (nee Uhler) Proc. Am. Phil. Soc. p. 424 IS73- This species was united by Le- Conte 1 and Horn with cariosus Ol., but wrongly so, as I shall attempt to prove. Olivier's description reads in substance as follows: Body black with dark cinereous coat- ing. Antennae brownish black, shining, cinereous at apex. Rostrum black, dark cinereous at base. Thorax uneven, "and one sees on t ^ ie su P er i r portion an ele- vation in the form of a cross> feebly marked." Elytra uneven, feebly vario- late, marked toward the apex with a callous point, nearly spinose, blackish, shining. Olivier's illustration is imperfect in that it is very crude, showing neither punctuation nor sculpture and the general impres- 1 Rhynch. N. A., p. 425. FIG. 20. Sphenophorus callosus. OF WASHINGTON. 77 sion is that of a shining species, which was certainly not intended. The thorax is a little short, otherwise the form coincides with the species which is figured herewith. The cinereous base of the rostrum is an important character, as it signifies that a considerable portion of the base is coated while in cariosus it is not. The cross-like elevation of the thoracic disc is aptly described as feebly indicated, in fact is requires a little imagination to discern it in many individuals ; moreover, it is not shown in Olivier's figure. In the true cariosus the cross is black, shining and well-marked, and the cariniform base of the third elytral interval which is always present is so prominent as to attract the attention of the veriest tyro. The type locality "Carolina" will answer for either species. North Carolina appears to be the metropolis of callosus. Sphenophorus cariosus Olivier. Sphenophorus sculptilis Uhler, Proc. Acad. Nat. Sci. Phila., 1855, p. 416 As the original description of sculptilis may not be acces- sible to many, it is transcribed below together with italicized words of my own and brackets to indicate portions of the description which are not specific. Entirely black, elevated portions shining; thorax with a sphenoid, poste- riorly acuminate, medial, and two undulating, prominent elevations. 8^ lines long to tip of rostrum. Baltimore. Black punctured; rostrum, rather robust, finely punctured at base sulcated [and dilated immediately in front of base; club of antennae, whitish at tip; thorax round, constricted in front, and slightly dilated a little before the middle], densely and coarsely punctured at sides, and between the elevations, puncta becoming finer anteriorly; scutel deltoid, excavated; elytra with two elevated, interstitial lines, a prominent elongated tubercle each side behind the humerus, and a round one near the apex of each elytron, sutural lines slightly elevated; [the three medial, and subsutural ones a little punctured at base; pygidium somewhat coarsely punctulate, punctures becoming finer at base; legs finely punctulate, patella more coarsely so; a large deep fovea upon the base of the post- pectus, posteriorly; venter with gradually enlarging punctures, increasing in size toward the base]. After carefully comparing several species with this descrip- tion I have come to the conclusion, in the absence of a knowl- edge of the whereabouts of Uhler's type, which cannot be located and may be destroyed, that it was based upon a some- what unusuallylarge specimen of 5. cariosus, which measure some- what less than "8^ lines" including the rostrum. Horn, in his 178 ENTOMOLOGICAL SOCIETY synopsis, recognized zecE Walsh as distinct from sculptilis Uhl . , but while the former is correctly described, showing that he had the Walsh species, he states of the second; "Body above entirely covered with dense argillaceous coating, ochraceous or pale brownish in color," which is never true of zece in any specimens which I have seen. Nevertheless LeConte 1 united these two species, sinking ze& as a synonym of sculptilis, at the same time that the name callosus was suppressed in favor of cariosus. To place Uhler's description in shorter words, it means a species about three-fourths of an inch in length, including rostrum, which is sulcated and finely punctured at base, "with two elevated, interstitial lines, a prominent elongated tubercle each side behind the humerus, and around one near the apex of each elytron." The rostrum of zecz is neither sulcated nor finely punctate at base. Moreover, no species which I have seen other than cariosus would be apt to be described in the terms of the first three lines of Uhler's descrip- tion and at the same time agree to the characterization of the elytra. The Calandra callosa of Olivier, according to the writer's interpretation, is entirely distinct from cariosus, as will be seen by reference to figure 20. Sphenophorus|zese Walsh. The name of this species, which was described in "The Practical Entomologist," 2 and in the 3d Report of the State Entomologist of Missouri, 3 may now be restored to technical entomology, as it has never been quite dropped out of economic writings. The description, and above all the figure, un- doubtedly from Walsh's type or cotype, is unmistakable. Sphenophorus soltauii, new species. Body subfusiform, half as wide as long; subopaque black, elevated portions somewhat feebly shining, no trace of alutaceous coating. Head deeply and rather densely punctate above the eyes, less distinctly and more sparsely on the vertex. Rostrum three-fifths as long as the thorax, irregularly feebly arcuate, considerably compressed; proximal fourth produced in front of the eyes, basal fourth variolately punctate, marked by a very short and fine median line (channel and interocular fossa wanting), strongly dilated at the sides, angles rounded; middle half of rostrum nearly straight and parallel as viewed from the side; apical fourth more compressed with inner angle not produced, obtuse. 1 Rhynch.

The median vitta takes the form of an irregular smooth, unelevated space of varying length, and ot a width about the same as an elytral interval; lateral vittae absent Scutellum sulcate with median line. Elytral striae irregularly, very deeply, coarsely, confluently punctate in the basal portion, becoming very narrow toward the apex.

Form moderately robust, resembling scoparius in size and proportions general color subopaque black on dorsal, moderately shining on ventral, surface. Larger punctures filled with gray extraneous argillaceous material. Antennae and tarsi slightly piceous, nearly black. Rostrum two-thirds as long as thorax, moderately, nearly uniformly arcuate, except at base and apex, where it is perceptibly and about equally compressed. Base strongly dilated, fully twice as wide as at middle of rostrum, strongly and angulately dilated over scrobes; basal fossa large, deep and broad near head, usually ending in a distinct line beyond dilated portion of rostrum. Apex flattened on anterior face, usually concave, on posterior face more or less strongly and acutely produced. Surface strongly punctate, very coarsely at base and finely at apex. Thorax about one-fourth longer than wide, moderately arcuate at sides; apex strongly constricted, with the extreme apical margin also strongly constricted on each side, the lower portion projecting beyond the upper. Surface very coarsely foveate-punctate, more finely on a slightly elevated area just in front of middle, and on two variable areas 180 ENTOMOLOGICAL SOCIETY (which resemble obsolete vittae) on each side of basal half. The spaces separating these from the median area are most coarsely punctate. Basal margin strongly ^bisinuate. Scutellum broadly but not deeply channeled at middle. Elytra one-fifth wider than thorax, one-third longer than wide, moder- ately narrowed toward apex. Striae fine, very coarsely and sparsely punctate, with punctures nearly as wide as the intervals, which they distort. Intervals all convex except at base, strongly punctate; larger punctures foveate; i finely, closely, and irregularly biseriately punctate (sometimes uniseriately) ; 3 with two or three series of punctures in basal third or less and uniseriate in remainder; 5 and 7 narrower than 3, but similarly punctate; 2, 4 and 6 sparsely foveate-punctate, punctures more than one-third larger than on i, 3 and 5; remaining intervals except at base very irregular and obscured by coating.

This species does not suggest any other in our fauna which has come to my notice. The projecting lower portion of the apical face of the thoracic constriction or collar is apparently peculiar to this species. Sphenophorus striatipennis, new species. Form of costipennis. General color red variegated with black, head and rostrum, median thoracic vitta, sutural intervals, abdominal seg- ments, metepisternum, coxae, knees, and tarsi black; somewhat weakly shining above, more polished on lower surface.

Evidently somewhat rare. Type. No. 9727, U. S. National Museum. The above description applies to the most distinct form of this species. There is, however, a color variation which does not seem deserving of a different name. It agrees with the typical form except in the fact that black is the predominating color; the vittae and intervals are all more or less shining black. This species is quite closely related to costipennis but is distinct by the more fimbriate tibiae, wider third joint of the posterior tarsi, and stronger punctuation of the lower surface. The typical form is distinct by color alone, but the less strongly marked form is duplicated by a Michigan specimen of costi- pennis (i in 300). This species as such was overlooked by Horn, as also by the writer, in considering species of the per- tinax group. The former mentioned it, however, as a variety "with the upper surface red, with the sutural interval and the median vitta black. The under surface is red varied with black, and the legs also red with the knees black." Sphenophorus sequalis Gyllenhal. This common, well-known species is quite different from ochreus Lee., the former being an eastern, the latter a western form; in fact, the two species are quite as distinct by many characters, more particularly by the punctation of the elytra and the coloration of the thoracic vittae, as are either from discolor Mann. The principal differences may be expressed in tabular form, as follows: Body covered with thick coating, subopaque on dorsal surface. Thoracic vittae pale, usually buff, distinctly elevated; median not wider at base than at apex; lateral with branch more or less indistinctly indicated; interspaces and sides distinctly deeply somewhat irregularly punctate. Scutellum coated, pale. Elytral striae with moderate rounded and deep punctures. Metasternum, first and second ventral segment c? concave and villous at middle; interior surfaces of femora and tibiae c? strongly 182 ENTOMOLOGICAL SOCIETY fimbriate.
