PROCEEDINGS OF THE ENTOMOLOGICAL SOCIETY OF WASHINGTON. VOL. XIV JANUARY MARCH, 1912 No. 1 MEETING OF NOVEMBER 2, 1911. The 253d regular meeting of the Society was entertained by Professor A. L. Quaintance in the Saengerbund Hall on the night of November 2, 1911, with twenty-five members (Messrs. Babcock, Baker, Barber, Busck, Crawford, Cushman, Dyar, Ely, Foster, Gahan, Gill, Hanimar, Howard, Jones, Knab, Myers, Popenoe, Quaintance, Russell, Sanford, Scott, Schwarz, Wal- ton, Webb) and two guests (Siegler and Wood) present. First Vice President Quaintance occupied the chair. The minutes of the previous meeting were read and corrected. The re- port of the committee to prepare the Obituary and Bibliog- raphy of the late D. W. Coquillett was submitted and re- ferred to the Publication Committee.* Mr. Schwarz proposed the name of Dr. K. Escherich, of Tharandt, Germany, for corresponding membership, to be acted upon at the next meeting. Mr. Gahan read the first paper of the program, "Descrip- tions of two new genera and six new species of parasitic Hymenoptera," which was followed by a short discussion on the confusion that has resulted from the publication of the supposed hosts of parasites. •Already published, Proc.

The descriptions of one new genus and three new species of Ichneumonoidea, one new genus and two new species of Chal- cidoidea, and one new species of Proctotrypoidea are contained in this paper. Types of all will be deposited in the United States National Museum. ICHNEUMONOIDEA. BRACONID^. MICROGASTERIN^. Apanteles (Pseudapanteles) terminalis, new species. 1900. Pseudapanteles terminalis Ashm. MS. in Smith's Ins. N. J., 1899, p. 593. Male. — Length 3.5 mm. Black, except legs and anal one-third of abdomen, which are brownish testaceous. Whole head, except occi- put, strongly rugoso-punctate and covered with short whitish pubes- cence; mandibles blackish brown; eyes hairy; clypeal fovea deep and rounded; labrum conspicuous; palpi pale yellowish; scape brownish testaceous, the flagellum wholly black. Thorax rugoso-punctate with whitish pubescence, the posterior half of the mesopleurae smooth, im- punctate. Propodium wholly rugoso-punctate, with distinct median and lateral carinae, the latero-posterior angles prominent, giving an appearance of concavity to the posterior face of the propodium. An- terior and median coxae brownish, posterior pair black, all trochanters, femora, and tibiae brownish testaceous, darkest above, all tarsi more or less dark brown, the two anterior pairs slightly testaceous. Wings hyaline, the costal, postmarginal, radius, first intracubital, apex of the median, and more or less of the discoidal veins and the stigma brownish; re ainder of the venation paler. First dorsal tergite one and one-half'"times as long as wide, the sides parallel or nearly, second segment half the length of the first, the third still shorter. The first three dorsal segments are strongly rugoso-punctate, the first two en- tirely black and the third with a broad crescent-shaped black spot basally, its lateral angles and apex like the following segments and ventral surface testaceous. Female. — Scape, pedicel, and three basal joints of the flagellum brownish testaceous; mandibles reddish brown; all coxae as well as femorae, tibiae, and tarsi pale testaceous; wing veins and stigma brownish testaceous. Ovipositor exserted about the length of the abdomen. Otherwise like the male. "Contribution from tho Entomological Laboratory of the Maryland Agricul- tural Experiment Station. OF WASHINGTON, VOLUME XIV, 191 1'. 3 Type: No. 12758, U. S. National Museum. Described from seven specimens, as follows: Three males from Jacksonville, Florida; one male from Cedar Point, Mary- land; one male and one female from Long Island, New York, and one male from College Park, Maryland. The College Park specimen is in the collection of the Maryland Experi- ment Station; all others are in the United States National Museum. The male and female from Long Island are un- doubtedly the specimens selected by Dr. Ashmead as types for the species. RHOGADINJE. ALLORHOGAS, new genus. Transfacial line equaling or nearly the facial line. Head transverse, the temples rather broad, two-thirds the width of the eyes; antennas long filiform; ocelli in a small equilateral triangle; labial palpi three- jointed, the maxillary palpi four-jointed. Head and thorax very finely reticulately sculptured; parapsidal furrows complete and deeply impressed, the median lobe of the mesocutum with a broad median longitudinal furrow; scutellum small; mesopleurae with a distinct fur- row; propodium more or less rugose, rather abruptly declivious pos- teriorly, with two distinct carinaa originating at the median point on the anterior margin and diverging in a curve posteriorly to the apex of the truncation, where they merge with the lateral longitudinal carinse. Wings with three cubital cells; the marginal cell completely closed; the recurrent nervure interstitial with the first transverse cubital; radius arising from the middle of the stigma, its first abscissa very slightly shorter than the second, the latter about half the length of the second abscissa of cubitus. Abdomen oblong-ovate, sessile, slightly longer than the thorax; the first segment longer than wide, striate with two carinae laterally at the base; second segment and apical half of the third strongly striate, the suture be^^veen distinct but not deeply impressed; ovipositor exserted about tw. ; the length of the abdomen. Type: Allorhogas gallicola, new species. In Ashmead's "Classification of the Ichneumon Flies" this genus would fall near Clinocentrus. It may be distinguished from that genus by the non-compressed abdomen. From Oncophanes and Epirhyssalus it is separated by the fact that the abdominal segments are not tumid. In Szepligeti's clas- sification of the Braconidae the genus agrees most nearly with Semirhytus, but the thorax is not smooth, the parapsidal fur- rows are deeply impressed, and the recurrent nervure is inter- stitial. The latter character differentiates it from Rhogm. 4 PROCEEDINGS ENTOMOLOGICAL SOCIETY Allorhogas gallicola, new species. Female — Length 4 mm. Antennas 30-jointed, the flagellum black- ish brown, darkest apically, the basal joints and scape somewhat tes- taceous. Face more distinctly pilose than the rest of the head, its sculpture, except on the median line which is nearly smooth, slightly coarser and more distinctly punctate than the vertex; mouth opening rather small; eyes, mandibles at the apex, and spot enclosed by the ocelli black; remainder of head, thorax, and abdomen brownish-testa- ceous; the metathorax and propodium slightly darker than the rest of the body; scutellum small, separated from the mesoscutum by a deep, wide furrow which is broken by several transverse ridges; carinas of the propodium with numerous short transverse striae radiating from them. Palpi and legs slightly paler than the body, the hind tibiae brownish and the apical joint of all tarsi brown. Wings hyaline; tegulas and veins at base yellowish; stigma and veins outwardly brownish. Apical half of third abdominal segment and base of the fourth faintly lineolate, others smooth; ovipositor blackish. Male. — Similar to the female in every respect except that the pro- podium is slightly more rugose and somewhat darker than in the female and the antennas are 28-jointed. Type: No. 14358, U. S. National Museum. Described from a single female reared May 20, 1911, and two males reared April 27 and May 18, 1911, respectively, at College Park, Maryland, from cynipid twig-galls on Quercus pinifolia. From these same galls were reared specimens of Synanthedon scitula Harris, and it is reasonable to suppose that the braconid is parasitic on that moth. In the National Museum are two specimens, apparently the same species, bearing the number 2610^- Ft. Grant, Arizona. The record to which this number refers shows that the specimens were bred from twig-galls of oak from the above-mentioned locality, and is interesting as indicating a wide distribution for the species. ALYSIIM;. DACNUSIN^E. Synaldis incisa, new species. Female. — Length 2 mm. Black; smooth and shining. Antennas submoniliform, brownish-testaceous, darker toward the apex; first flagellar longer and more slender than the second, the second not twice as long as thick, following joints shortening and narrowing grad- ually toward the apex, about one and one-half times as long as wide, the joints toward the apex slightly pedicellate. Head smooth and shining; face somewhat pilose, with a faint median carina between OP WASHINGTON, VOLUME XIV, 1912. 5 the antennae: vertex divided by a deep median furrow extending from the ocelli to the occipital foramen. Mesothorax smooth, shining im- punctate; the parapsidal furrows absent, the mesoscutum with a short median longitudinal furrow or incision near its posterior margin; meso- pleurae with a distinct furrow; propodium rugose with a short median carina anteriorly becoming lost in the roughness of the sculpture pos- teriorly. Wings hyaline; the stigma very narrow, only slightly thick- er than the postmarginal vein, which is thickened throughout its whole length; the first cubital cross-vein is entirely absent, the second re- moved nearly one- third the length of the radius from the origin of the latter; the cubital nervure abruptly cut off just beyond the cross-vein; marginal cell reaching to the apex of the wing; costal, radial and postmarginal veins and the stigma brownish, remainder of the neura- tion pale. Palpi and legs brownish-testaceous, darkest above. Ab- domen not longer than the head and thorax, smooth, shining, black; ovipositor exserted half the length of the abdomen, brownish-testa- ceous. Habitat: Manhattan, Kansas. Type: No. 14357, U. S. National Museum. Two slides bearing a large number of specimens were re- ceived from T. J. Headlee for identification. These speci- mens were taken from cages in which the Hessian fly was breeding and are possibly parasitic on that insect. The species may be distinguished from S. nhtiicola Ashm. by the incision on the mesoscutum and by the more rugose propodium. Types removed from slide and mounted on points; paratypes in the collection Kansas Agricultural College, slide-mounted. CHALCIDOIDEA. TORYMID.E. MONODONTOMERIN^E. Ditropinotus flavicoxus, new species. Female.— Length 2.5 mm. Head and dorsum of the thorax golden green, strongly punctate, the punctures of the head somewhat finer than those of the thorax. Antennae dark brown, nearly black; the scape and club orange yellow. Face below antennae with sericeous white pile. Pleura?, underside of thorax (except mesosternum, which is usually green), legs including all coxae, and abdomen honey-yellow; the anterior coxae and middle tibiae are usually somewhat paler than the rest of the legs, and the apical tarsal joints are dark. Abdomen very finely, transversely lineolate, the ovipositor about half the length of the abdomen and black. 6 PROCEEDINGS ENTOMOLOGICAL SOCIETY Male. — Entirely green, the abdomen slightly bronzed above. An- tennas wholly black. Coxae and femoras, except apically, dark brown, the tibiae, tarsi, and apices of femoraa pale yellow. Body sculpture similar to that of the female. Habitat: College Park, Maryland. Type: No. 14356, U. S. National Museum. Eight female and six male specimens collected by Mr. E. N. Cory, July 19, 1909, in a room in which were stored quan- tities of meal and other ground feed badly infested with several different coleopterous and lepidopterous pests of this class of stored products. It is probably, though not certainly, para- sitic on some insect which infests stored cereals. The species differs from D. aureoviridis Crwfd. in the female having all of the coxae honey-yellow instead of green and in the absence of any green markings on the abdomen. The sculpture of the propodium is also slightly different. The males are not distinguishable. ENCYRTID.E. ENCYRTIN^. AGROMYZAPHAGUS, new genus. Body metallic. Head transverse, seen from in front slightly broad- er than long; cheeks half the length of the eyes; eyes bare, nearly circular, converging above and extending to the occiput; vertex rather narrow; frons somewhat flattened, finely punctate, and with numerous larger, deeper punctures surrounding the forward ocellus; ocelli in a nearly equilateral triangle, the two lateral close to but not touching the eye margins; antennae 11-jointed, inserted below the eyes, the scrobes triangular; scape slender, not reaching to the front ocellus; pedicel shorter than the first funicle joint; funicle joints thickened, cylindrical, the first joint slightly the longest, following joints sub- equal, one and a half times as long as wide; the club is flattened, not as long as half the funicle, its apex bluntly rounded, the first joint slightly longer than wide, the two following transverse. Thorax ro- bust; mesoscutum short and broad, not more than half as long as wide and very finely shagreened; scutellum convex, as long as the meso- scutum, rounded posteriorly and delicately sculptured; metathorax smooth, impunctate, and without pubescence. Wings hyaline; the marginal vein short, not much longer than thick; postmarginal shorter than the marginal; stigmal about as long as the marginal and post- marginal together. Abdomen conic ovate, flattened above, not longer than the thorax; ovipositor not exserted. The male differs from the female in having the club of the antennas shorter than the two pre- ceding funicle joints, the funicle joints hairy, not especially thickened, OF WASHINGTON, VOLUME XIV, 1912. 7 and distinctly notched above at the sutures; the first funicle joint is two or more times as long as the pedicel. 7ype: Agromyzaphagus detrimentosns, new species. In Ashmead's Classification of the "Chalcid Flies" this genus apparently falls nearest to Coccidenc\rtns, but differs from that genus in that the antennal club is less than half the length of the funicle. The fact that the eyes are bare distin- guishes it from Ageniaspis and the short pedicel will serve to separate it from most of the other genera. Agromyzaphagus detrimentosus, new species. Female. — Length 1.5 mm. Antenna? black with very short whitish pile, scape slightly metallic; scrobes deeply impressed; eyes reddish brown; face and cheeks bluish-green tinged with brassy, the former finely shagreened, the latter delicately lineolated. Head above and mesocutum finely shagreened, brassy green; scutellum copper-colored its sculpture finer than that of the mesoscutum; mesopleurse steel- blue, very finely lineolate; metathorax and abdomen smooth, shining, impunctate, nearly black, but often slightly metallic. Wings hyaline, the anterior and posterior margins without cilia, the apical margin with very short cilia; veins brownish. Coxae all metallic green; tro- chanters testaceous; anterior femorse dark brown, their apices and tibiaa and tarsi pale yellow; median femorse and tibiae dark brown, the apex of femoras, base and apex of tibia?, and their tarsi pale yellow; posterior femorae and tibiaa black, more or less metallic, their tarsi yellowish. Male. — Exactly like the female, except in the antennal characters, as pointed out in the description of the genus and the fact that the flagellum is wholly testaceous instead of black. Type: No. 14355, U. S. National Museum. Habitat; College Park, Maryland. Described from eleven females and seven males reared July 19, 1911, by Mr. O. G. Babcock and the writer, from the pu- paria of an agromyzid fly belonging to the genus Leucopis. The flies, which are probably Leucopis uigricornis, were feed- ing in the larval state upon an aphis infesting apple and also one infesting a species of thistle. PROCTOTRYPOIDEA. PROCTOTRYPID^. SCELIONIN^. Hoplogryon kansasensis, new species. Female. — Length 2.5mm. Black, more or less shining. Antennae strongly clavate; scape long and reaching about to the forward ocel- PROCEEDINGS ENTOMOLOGICAL SOCIETY lus, slightly testaceous; pedicel conical, much narrower and less than half as long as the following joint, dark brown; flagellum about twice as long as the scape, blackish; the first joint not wider at base than the pedicel but much wider at its apex, second joint distinctly shorter than the first, one and a half times as long as thick, third and fourth joints subequal, transverse, about twice as wide as long; club joints transverse, but distinctly longer than joints three and four of the funicle, the two apical sutures slightly oblique, the apical joint round- ed at its apex. Head black, strongly transverse; mandibles deeply toothed and brownish; clypeus strongly transversely striate; lower part of face, eye margins above, the temples, cheeks, and vertex also deeply striate; remainder of the face smooth and shining but with many deep punctures arranged in irregular rows on the upper half. Thorax black; mesothorax and scutellum coarsely punctate, meso- pleura? rugoso-striate; metathorax more or less rugoso-striate with three long pointed projections, one on the median line reaching to the middle of the first abdominal segment, and one at each posterior lateral angle considerably shorter. Wings slightly smoky, with a row of stiff black bristles along the subcostal and marginal veins. Legs in- cluding all coxae brownish testaceous. Abdomen shining black, longer than the head and thorax, spatulate, the first segment wider at apex than long, its base narrow; second segment also much wider at apex than at base and about half as long as wide; third segment as long as two and three together, the following segments very short; segments one, two, and three are strongly longitudinally striate, the striations gradually fading out and disappearing before the apex and at the sides of the third. Habitat: Manhattan, Kansas. Type: No. 14354, U. S. National Museum. One specimen was received from T. J. Headlee which had been secured from a cage in which experiments with the Hes- sian fly were being carried on and it is possibly, though not likely, a parasite of the fly. The species is closest to H. bethunei Sanders, recently de- scribed, but differs as follows: The thorax is densely punc- tate instead of rugose, the metathoracic teeth are much longer, and the flagellum is more strongly dilated. —Mr. Busck gave a very interesting account of the rearing of the man-infesting bot of tropical America. OF WASHINGTON, VOLUME XIV, 1912. 9 ON THE REARING OF A DERMATOBIA HOMINIS LINNAEUS. BY AUGUST BUSCK. The literature on Dermatobia infesting man is very large and the biology of the species is fairly well studied and un- derstood. Dr. Raphael Blauchard, in his classical paper, "Sur les (Kstrides americains dont la larve vit dans la peau de 1' homme" (Ann. Soc. Ent. France, vol. 61, pp. 109-154, 1892), gives a comprehensive review of the literature on this species from the first record in 1749 to the date of his article, and Dr. A. Neiva has lately given full synonymy and life-history with illustrations of all stages in his "Algumas iuformacoes sobre o Berne" (Chacaras e Quintaes, vol. n, no. 1, 1910, reprinted as a separate publication in Rio de Janeiro, 1911). The following notes do not pretend to add anything new, but are merely an account of an actual breeding of the para- site from man, of which there is as yet no published record. The writer has on several occasions become infested with the larva of Dermatobia, but has been unable to indulge his desire to breed the fly, because the inconvenience of an infes- tation interfered with work on hand. Acquiring, however, an infestation towards the close of my last stay in Panama, this summer, and in a reasonably inoffensive part of the body, upper left arm, I determined to let it remain and succeeded in rearing the fly. The infestation took place at Cabima, Panama, on May 29; only one cast skin was observed during the larval period; this was shed and pushed out nearly entire through the aperture in my skin on July 19; on September 9 the larva had at- tained full growth and left the arm, posterior end first. It was at this time nearly 1 inch long (24 mm.) and 10 mm. in diameter. On being placed in a jar with wet sand it immedi- ately burrowed down 2 inches to the bottom of the jar and pupated. The fly issued on October 23. No exact observation on the oviposition is recorded in print and none was made by the writer; the egg is known only from dissected females, but there is no doubt that the larva hatches at once at the time of oviposition and normally bores into the skin just where it is deposited; for this reason the bulk of the infestations occur on exposed parts of the body, the arms, legs, and neck; but it is plainly either possible for the larva to travel some distance, if not satisfied with its first situation, or else survive a fall from this exposed place to another under the clothing of the host; the writer was thus infested by another larva earlier in the season just under the 10 PROCEEDINGS ENTOMOLOGICAL SOCIETY shoulder blade, whereto the larva must have dropped or crawled from the neck. All my other infestations occurred on places which were exposed at the time. The natives believe the swellings on their legs are caused by their wading across streams, at which time of course the fly has a good opportunity to oviposit. To any observing person the infestation is noticeable from the very beginning, and the irritation is easily distinguished from the abundant mosquito and tick bites with which one is inflicted when "in the bush." Within a week can be seen with the naked eye the charac- teristic, moist aperture in the skin through which the larva pushes and withdraws its anal end for breathing. The larva, even when large, does not cause much pain if not interfered with, though it has the habit at times of rotating around its own axis with telling effect on the host's feelings. On the whole, however, the inconvenience is greater than the pain, the constantly exuding faeces of the larva necessita- ting a bandage so as not to soil underclothing and bed linen. Towards maturity the larva gradually enlarges the aperture in the skin and its final egress is more relief than pain. But I am inclined to ascribe to the larva a more serious effect on its host. During no period of my entire adult life have I required as much sleep as during the months of infestation with this parasite; from 3 to 5 hours were almost daily regretfully added to my normal sleeping hours and during the day I felt less alert and energetic than is my wont. This was the more noticeable to myself and to my nearest associates, because I for more than twenty years have been in the habit of indulging in a minimum of sleep. When the larva had left my arm this desire for sleep stopped and I was able to return to my normal habits. I am well aware that the evidence of this single experience is not sufficient to establish the guilt of the larva; other causes not perceived by me may have produced my condition, but I wish to record my belief that the Dermatobia larva was the cause. Is it not possible that these larvae produce some virus which has a quieting effect on the host? Ability to quiet the host during incubation would be a distinct advantage to the species. During his stay in Panama the writer observed what is now known to be the same species in monkey and dog. Having been the victim of a pretentious surgical operation, with subsequent stitches and bandages, which was thought necessary to remove a half-grown larva in my back, which I could not myself reach around and attend to, I may be ex- OF WASHINGTON, VOLUME XIV, 1912. 11 cused a note on the technique of removing such a larva from a suffering host. There is no need of knife and bloodshed; at any time of its life the larva may be easily removed simply by pressure, after the aperture has been softened and some- what enlarged by insertion of a pair of thin forceps; but the shape of the larva should be kept in mind; its thin anal end lies toward the surface of the skin and the swelled bottle- shaped part is downwards; hence it is necessary to apply the pressure well below the swelled part or it will only tend to force the larva further down. Mr. Knab spoke of the widespread and common occurrence of Dermatobia throughout tropical America and of the Mex- ican and Central American records in numerous papers that have appeared on the subject. Several different species have been thought to exist, but it now appears that they are all one. Both Aldrich and Coquillett seem to have been skeptical of the occurrence of Dermatobia north of Panama, or unable to cope with an insect usually observed only in the larval stages. Mr. Busck said that in Trinidad the larvae commonly infested the head, but this was not so in Panama. Mr. Knab said there are no actual observations on the mode of oviposition. The several stages of the larvae differ and were at one time considered different forms. In tropical Africa a muscid para- site of man ( Cordylobia) lives under the skin in the same way. It was supposed that the eggs were deposited directly on the exposed skin, as persons bathing became most frequently in- fested. Recently von Pelser-Berensberg determined that the eggs are not deposited directly upon the skin but on the clothing and do not hatch until two days later. Mr. Hammar said that while in South America he had been infested with Dermatobia several times. There appeared to be two kinds of larvae, black and white. The natives believe the eggs are laid on the foliage. He had found young larvae crawling on the skin before entering. Mr. Crawford spoke of the finding of a cast skin in the burrow with the maggot which he was having cut out in Costa Rica. Mr. Schwarx spoke of Dr. LeConte's observations and method of extraction as published in his edition of Say's entomolgical writings. Mr. Hammar said the native remedy was to tie chewed tobacco over the hole. Mr. Knab stated that the larva does not penetrate below the connective tissue. 12 PROCEEDINGS ENTOMOLOGICAL, SOCIETY -Mr. H.

Russell, under the title "A Hymenopterous Parasite of Thrips," gave an abstract of his observations in California.* -Under the heading Notes and Exhibition of Specimens Dr. Dyar called attention to a published charge by Prof. John B. Smith that type labels in the National Museum had been tampered with (Journ. N. Y. Eut. Soc., xix, 151, 1911). He said that the basis of this serious charge was that Professor Smith had, a number of years ago, confused together two similar species of Noctuidse. Smith had described a species from four specimens, and, as it now appears, of these he left two in the National Museum and took two for his own collec- tion. It so happened that the two in the National Museum were of one species, the two in Smith's hands, another. Re- cently Smith, in revising the genus, based the species in his redescriptiou upon the specimens in his hands and described the other form under a new name, unconscious of the fact that this form already constituted part of the types of his earlier species. Dr. Dyar had pointed out, from the types in the National Museum, that Smith had redescribed his own species, and he proposed another name for the species which Smith held under the old name, being unaware of the exist- ence of other types in Smith's hands. Hereupon Smith claimed that the types in the National Museum were really conspecific with those in his hands and that if they were not so, then the type labels had been changed! He states that the two species are "so utterly different in size, in color, in mac- ulation, and even in wing form, that mere error of association is excluded." Dr. Dyar expressed himself as deeply incensed at this ridic- ulous charge, which, he said, was prompted by malice and supported by misstatement. He exhibited specimens of the forms in question, showing that they were in fact near allies and not widely separated species, as Smith's statements would imply. Such might very easily have been originally confused by Smith. In fact, Smith in his original description refers *Already published, Proc. Ent. Soc. Wash., xni, 235, litll. OF WASHINGTON, VOLUME XIV, WlL>. 13 to the great variability of the form before him. Dr. Dyar further stated that he had a suspicion that the forms would ultimately prove to be varieties of one species, in which case it would be found that Smith's earlier position, which he now so radically repudiates, was in fact the more correct one. In regard to the names of these forms, Dr. Dyar said that in spite of the discussion, the types of the original Plconectyp- tera fiuitima Smith had not been fixed. The species was based on four specimens and Dr. Dyar proposed herewith to restrict the types to the two in the National Museum. This makes P. tcnalis Smith synonymous with P. fniitiina, and leaves the name P. ciimulalis Dyar available for the other form, all as stated in Dr. Dyar's paper published in the Pomona College Journal of Entomology. — Mr. Walton presented the following: NOTES ON CERTAIN SPECIES OF FLIES. BY W. R. WALTON. Microdon laetus Locw. The writer has already published a note regarding this syrphid in Entomological News. It is listed among the ad- ditional species but not described in Dr. Williston's Synopsis of the North American Syrphidse. The type locality is Cuba, but the present specimens were collected near Harrisburg, Pennsylvania, by Mr. Frank Craighead and H. L. Adams, re- spectively. There is also one additional specimen in the col- lection of Mr. E. Daecke at Harrisburg, which was collected by the writer. Eristalis montanus Williston. Dr. Willistou described this species from a unique male taken at Como, Wyoming, at an elevation of 7,000 feet, and the female has since been described by Mr. W. D. Hunter (Can. Eut., vol. xxvm, p. 98). Specimen was taken at Soda Springs, Idaho. Mr. Hunter subsequently collected several specimens in northwestern Nebraska. All the specimens so far recorded have been taken at elevations exceeding 4,000 feet. The present specimen was collected at Real del Monte, Mexico, a silver-mining camp 9,000 feet above sea level, by Mr. H. T. Van Ostrand. This is one of the few species of Eristalis from North America not hitherto represented in the collection of the U. S. National Museum. 14 PROCEEDINGS ENTOMOLOGICAL SOCIETY Eristalis vinetorum Fabr. The present specimen was collected at Hertford, North Carolina, by the writer, during the past summer. This seems to be the most northerly latitude yet recorded for the species, which is common enough from Georgia southward. Synthesiomyia braziliana B. & B. This species, the type locality of which is Brazil, has hith- erto been recorded from but few localities in the United States. Hough records it from Florida and Georgia and Mr. H. G. Hubbard collected one specimen from a cave in Florida, which by the way, is credited in Aldrich's catalogue to Mr. C. W. Johnson, who first published the record. The present speci- men was collected by Mr. D. K. McMillan at Brownsville, Texas. It is herewith exhibited in company with a species of Sar- cophaga in order to call attention to the extreme similarity in habitus of the two species. Johnsonia elegans Coq. Mr. Coquillett erected the genus Johnsonia for this species on a single specimen, collected by Mr. C. W. Johnson, at St. Augustine, Florida, in 1895. Mrs. Annie Slosson subse- quently collected several specimens in the same State. The present specimen was taken at Eberlys Mill, near Harrisburg, Pennsylvania, by the writer, The genus is undoubtedly a valid one, but the several individuals to which Mr. Coquillett has applied a common specific name differ so markedly as to indicate that at least two species may be included. The present individual is one-third again as large as the type specimen and has been determined by Mr. Coquillett. It is exhibited in company with a tachinid fly, namely, Tricophora riificanda van der Wulp, to which it bears a re- markable, though of course superficial, resemblance. —Dr. Dyar spoke of the larva of Doa ampla Grote, which had been sent to him by Prof. T. D. A. Cockerell. Prof. Cockerell found the larva at Boulder, Colorado, on an euphor- biaceous plant, and originally sent it for determination. Dr. Dyar at that time had no idea what it was; but later Prof. Cockerell succeeded in breeding the adult. Dr. Dyar said that the species had been variously referred to different fam- ilies, having been first described as a lithosian, in the Euro- pean genus Emydia Boisd. The moth by its venation is OF WASHINGTON, VOLUME XIV, 191:?. 15 neither a lithosian nor an arctiau, nor does it belong to the Liparidse. It will come in the group called Hypsidae by Sir G. F. Harupson, a group including the forms that we have classed under the term Pericopidae. The larva is smooth, brightly colored, the setse degenerated and nearly lost, but the subventral ones with duplicated hairs. It is thus the possessor of many-haired warts, which have degenerated to give place to a bright and conspicuous coloration. The larvae of the Pericopidae possess a similar structure, except that in general the warts and hairs are well developed and functional, although in some, like Coinposia fidelissima H. S., the hairs are few and the coloration of the skin is bright. Therefore there is nothing in the structure of the larva of Don umpla to prevent its reference to the Hypsidae. Dr, Dyar further said that he would add a description of the larva for publica- tion, which follows: Larva. — Head small, rounded, notched behind at the vertex, flat before, smooth shining black, the epistoma and bases of antennae white. Body with the thorax roundly enlarged, swollen, the rest evenly cylindrical, subtruncate behind. The enlarged thorax is black, with large rounded angular white spots, while the central region is yellow with broad black bands. Thoracic white spots subdorsal and lateral on joints 2 and 3; on joint 4 they are yellow, the lateral one partly divided; broad black dorsal and lateral stripes on joints 5 to 12, the lateral one joined to a series of quadrate black patches in the centers of the segments; subventral region and bases of feet black; venter pale. On joint 11 posteriorly to the end of the body the black color again prevails, broken by a subdorsal and lateral white spot on joints 12 and 13. Thoracic feet and anal shield black. Cocoon. —An open mesh of brown silk, in which the pupa has con- siderable play. The cast larval skin is included. The pupa is uni- formly brown. -Mr. Schwarz remarked shortly on the northward flight of the cotton worm moth (Alabama argillacea), a phenomenon which has not been observed in the city of Washington for about twenty-five years. During the present year, 1911, the moths were first observed in the city on September 19 and from that date they were observed almost daily until Octo- ber 19, being present sometimes in enormous number of spec- imens. They were also observed on Plummer's Island, Mary- 16 PROCEEDINGS ENTOMOLOGICAL SOCIETY land, on September 23 and October 3, where they were attracted by the acetylene light. In this connection Doctor Howard stated that he and Dr. K. Escherich, of Tharandt, captured an apparently fresh female of the cotton moth on the window of a parlor car going into Chicago on the afternoon of September 25. He also stated the following instances of northern distribution for this au- tumn had come to him in his general correspondence: Through the summer reports of damage by the larvae came frequently from various parts of the South. September 15, they were reported as ruining the cotton at Norfolk, Virginia. (T. C. Johnson.) September 16, the moths were sent in from Romney, West Virginia, where they had been damaging peaches. (J. J. Cornwell.) September 22, they were sent in from Lookout Mountain, Tennessee, where their occurrence in the house in numbers had alarmed the housekeeper. (Mrs. M. W. Gill.) September 25, they were captured at Indiana, Pennsylvania, under an arc light, and sent to the Bureau. (G. W. Sloop.) September 26, they were reported from Cincinnati, Ohio, as damaging ripe fruit, especially peaches, so that it was neces- sary to pick the fruit in order to save it. (J. Benckenstein.) September 28, reported from Agate, Nebraska, as swarming about the lamps by thousands and being very annoying in houses. (S. D. C. Bassett.) September 29, they were sent in as congregating about the arc lights in Cumberland, Maryland. (J. G. Lyon, Jr.) The same date, they were received from Indianapolis, Indi- ana. (B. W. Douglass.) The same date, from Richmond Hill, Long Island, New York. (W. A. Bernhard.) September 30, Keokuk, Iowa, hundreds of the moths col- lected on windows and telegraph poles. (J. M. Shaffer.) October 2 and 5, they were reported in occurring in mills at South Haven, Michigan. (H. Haupt, Jr.) October 10, reported as occurring in the streets in New York City, Yonkers, Brooklyn, and Newark, and as occurring in numbers in the upper stories of tall buildings. (Theo. Mead.) OF WASHINGTON, VOLUME XIV, 1912 17 October 13, reported from Fairmont, West Virginia, as having been destroyed by the hundreds of thousands by the lights of the town. (H. A. Williams.) October 18, Charleston, West Virginia, millions reported covering poles and the ground near electric light following an almost continuous rain for 24 hours. (W. O. Daum.) October 19, reported as swarming in an orchard at Good- land, Indiana, by thousands. (Miss Myrtle E. Alter.) October 20, Beaver Falls, Pennsylvania, moths flying about the lights at night in great numbers. (M. R. Tullis.) October 30, correspondent at Shephard, Ohio, reported that one night in September a light shower fell and the next morning the premises were covered with these moths. (Mrs. Chas. Matthews.) Mr. Gahan spoke of letters from four correspondents of the Maryland Experiment Station, which tell of extensive swarms of this moth in the western part of the State during the latter part of September and earl)- part of October. The first letter is from D. W. Crowther, Smithsburg, Washing- ton County, under date of September 20, and states that the moths are abundant in his peach orchard, and that they collect in large numbers on the specked fruit. September 28, Mr. Edward Harris, of Cumberland, Allegany County, sent specimens and stated that the moth was present in larg-e num- bers in the city of Cumberland. Again on October 4, Mr. Harris wrote that the moth was still plentiful and that it had been reported from Piedmont and Keyser, West Virginia. October 2, a correspondent of a Baltimore paper, whose letter was referred to the experiment station for reply, wrote that Allegany County was deluged with the moths, which collected on the electric-light poles in such numbers as to cover them. October 4, G. W. Thomas, of Adamstown, Frederick County, sent specimens and stated that they were abundant in his vineyard, where they were apparently eating- the punct- ured grapes. Numerous specimens were observed by the speaker on the windows of his home at Berwyn, Maryland, one evening dur- ing the first week in October. 18 PROCEEDINGS ENTOMOLOGICAL SOCIETY MEETING OF DECEMBER 7, 1911. The 254th regular meeting was entertained in the Saenger- bund Hall, 314 C street N. W., by Dr. L. O. Howard. Presi- dent Webster occupied the chair and twenty-six members (Messrs. A. C. Baker, Banks, Barber, Busck, Caudell, Cory, Cushman, Dyar, Ely, Heidemann, Hopkins, Howard, Hyslop, Jenne, Fred Johnson, Knab, McAtee, Myers, Phillips, Roh- wer, Sanford, Sasscer, Schwarz, Vickery, Viereck) and four visitors (Messrs. Demuth, Grosvener, Urich, and Siegler) were present. The minutes of the 253rd regular meeting were read and approved. Mr. Rohwer read his report as Secretary-Treasurer. The Chair appointed Messrs. Banks and Caudell as auditors. Dr. Howard moved the report be accepted and placed on file and that the recommendations contained in it be referred to the executive committee. The Chair introduced the subject of the approaching meet- ing of the A. A. A. S. with its attending corps of visit- ing entomologists. Motion was made (Schwarz), seconded (Knab), and carried that it is the sense of the Society that we entertain the entomological contingent at a smoker, the expenses to be paid by subscription. Mr. Schwarz stated that at an Executive Committee meeting he had been appointed a committee of one to investigate and find what arrangements could be made. That the only available place and time ap- pears to be the Saengerbund Hall, Friday night, December 29. Motion to accept the arrangements as made was carried. Dr. Howard moved that Mr. Schwarz as chairman of the committee of one for these arrangements be authorized to in- crease its membership as desirable. Carried. Mr. Schwarz moved the election of Dr. K. Escherich, of Tharandt, Germany. Carried. Under new business Mr. Rohwer read the proposed amend- ments to the Constitution. Mr. Caudell moved their adop- tion, seconded by Mr. Knab. Carried. Mr. Rohwer moved that the Society publish the revised Constitution in the first number of the forthcoming volume, Seconded by Mr. Cau- dell. Carried.

BY A. A. GIRAULT. Several months ago I sent in the manuscript of a paper de- scribing a North American species of Mymaridfe from a single male specimen sent to me from Canada and which I named Dicopus halitn.s. While on my way to Australia in Septem- ber, 1911, I had an opportunity of stopping off for a few hours at Suva, Fiji, and during that time managed to collect a few parasitic Hymenoptera. Among these was a single male mymarid geuerically allied with the American iormhalitiis and which also must be for the present referred to the same genus. This Fijian species, like the American form, is very minute, also extremely delicate, and was extraordinarily difficult to cap- ture; it was moving slowly over the pane of a window, but I was not able to keep sight of it for more than the fraction of a second at a time. This fact, taken in conjunction with its fra- gility, made it necessary to spend three-quarters of an hour in effecting its capture. Thereafter I was exceedingly fortunate in being able to transfer it to a slide of xylol balsam, consid- ering the circumstances and lack of facilities for such work. Whether the species is indigenous to the Fiji Islands or not cannot now be determined, especially since our knowledge of the Mymaridae is so scanty. For obvious reasons I believe it incumbent on me to describe the form, which is done herewith: Dicopus psyche, new species. Position normal; abdomen sessile; tarsi 5-jointed. Male. — Length, 0.20 mm. Very minute; visible as a mere fleck of dust. General color grayish, the legs and antennae concolorous; fore wings characteristic because of the fact that they are clouded through- out, but in the distal part of the wing blade the clouded area is more confined to the midlongitudinal line of the wing and is consequently margined with a hyaline area in that part. The edges of the fore wing are as usual yellowish. Distal half of the abdomen and coxa? darker; trochanters pallid. The same as Dicopus halitus Girault, but differing in the following structural characters: In the fore wing there is no midlongitudinal line of discal cilia in the distal part of the blade; excepting a single short line of two or three minute seta?, and along each side, between the margin and the middle line, a single line of larger setae, this line extending to the apex along each side; the middle line is obscure and at the base of the distal third of the wing and does not reach the apex OF WASHINGTON, VOLUME XIV, 1912. 23 by some distance. In the antenna a marked difference in that the second funicle joint is not abruptly narrower and slightly shorter than the first, but of equal width and distinctly longer (nearly twice longer) ; the scape is long, thrice or more the length of the pedicel; the first funicle joint is subequal in length to the pedicel; funicle joints 3 and 4 aresubequal, longest of the funicle, each a fourth or more longer than funicle joint 2; funicle joints 5, 6, and 7 subequal, shorter, each slightly longer than joint 2 of the funicle, 8 and 9 subequal, slightly longer, club joint conical, somewhat shorter than funicle joint 9. Scape by far the longest antennal joint. Pubescence of antenna inconspicuous. Female. — Unknown. Described from a single male specimen captured from the pane of a window in a woodworker's shop, Suva, Fiji, during the afternoon of September 22, 1911. A species characterized by the color of the wings, the grayish body color, and struc- turally by the slender and moderately long second joint of the antennal funicle. Host: Unknown. Habitat: Fijian Islands (Suva). Type: No. 14483, U. S. National Museum, Washington, D. C. ; one male in balsam. A NEW SPECIES OF THE MYMARID GENUS POLYNEMA HALIDAY FROM BRITISH COLUMBIA. BY A. A. GIRAULT. The following new species is not included within the census of Mymaridae of North America recently published by me.* It seems to be quite distinct from any of the forms so far de- scribed from the United States or Mexico and is the first species of the genus to be recorded from Canada. A second species, common in the United States, is also recorded from Canada. FAMILY MYMARID^. SUBFAMILY MYMARIN^. TRIBE MYMARINI. Genus POLYNEMA Haliday. i. Polynema striaticorne Girault. A single female specimen of this species was captured by sweeping in original forest, Stanley Park, Vancouver (B. C)., Canada, Septembers, 1911. It had broader fore wings than *Trans. American Ent. Society, Phila., xxxvn, pp. 25:i -:;.'!. 24 PROCEEDINGS ENTOMOLOGICAL SOCIETY usual and the caudad coxae were more yellowish than with the average specimen of the species. 2. Polynema regina, new species. Position normal. Female. — Length, 0.90 mm. ; moderately small for the genus. Gen- eral color black; legs, petiole of abdomen, antennal scape, and pedicel intense orange yellow, the former tinged with dusky only in places— the cephalic femora at proximal third and all tibiae slightly along their middles exteriorly; distal tarsal joint, however, black; first four funicle joints of antennas diluted with yellowish. Wings hyaline.' Another species falling within the group of allied species containing consobrinus Girault, aspidioti Girault, striaticorne Girault, howardii Ashmead, euchariforme Haliday, and brit- tanum Girault, but resembling more nearly the first. It differs from it as follows: In the nearly uniformly intense yellowish legs, antennal scape and pedicel, and abdominal petiole; then in the shape and ciliation of the fore wings — the discal ciliation is somewhat coarser, the individual cilia some- what longer, but there are about the same number of longi- tudinal lines; the marginal cilia are distinctly longer at all margins, the longest (caudo-distad) about three-fourths the wing's greatest width; those at the apex of the wing are nearly as long as the longest cilia of the fore wing in conso- brinus; the longe'st are twice the length of the longest cilia of the caudal wing, which is not true for consobriiins, where the the two sets of cilia are more nearly equal. The proximal tarsal joints are somewhat longer in regina. Otherwise about the same. Male- Unknown. Described from a single female specimen captured with the species recorded above. Habitat: Canada — Vancouver, British Columbia. Type: No. 14512, U. S. National Museum, Washington, D. C., one female in xylol balsam (mounted on a slide with a specimen of striaticorne and a proctotrypoid). A species characterized by the intense orange-yellow legs, the short proximal funicle joint of the antennae (distinguish- ing it from such species &s psecas Girault and cnockii Girault) and the shape and ciliation of the fore wings. It should also be compared with the species like maculipes Ashmead, zetcs Girault, and longipcs Ashmead. OP WASHINGTON, VOLUME XIV, 1912. 25 A REVISION OF THE GENUS LASCONOTUS ER. (Coleoptera; Colydiidse.) BY E. J. KRAUS.* Since 1890, when Colonel Casey published descriptions of several new species of Lasconotus, practically nothing has been written concerning the species occurring in the United States. In the interval several new forms have accumulated, and the present opportunity is taken to describe them and make a complete revision of the genus. In the synopsis of species will be found the type locality of each species, and under the discussion of species will be found a complete list of localities from which specimens have been examined. The designation Hopk. U. 8. refers to speci- mens in the Forest Insect Collection, largely collected by Dr. A. D. Hopkins, H. E. Burke, J. L. Webb, and W. F. Fiske during investigations in the Branch of Forest Insect Investi- gations of the Bureau of Entomology. The designation U. S. N. M. refers to specimens in the U. S. National Museum. For the latter, credit is given in each case, where known. I wish to express uiy sincerest thanks and appreciation to Mr. E. A. Schwarz, who turned over to me the abundant ma- terial in this group in the U. S. National Museum for study, and to whom I am greatly indebted for more numerous kindly helps and suggestions throughout the preparation of this paper than I can well enumerate; to Dr. A. D. Hopkins, who has kindly allowed me free use of all the material and notes in the Forest Insect Collection; to Mr. S. Henshaw, of the Museum of Comparative Zoology, at Cambridge, Mass., for the privi- lege of making a personal examination of the LeConte types; to Dr. H. Skinner, of the Philadelphia Academy, who extended a like courtesy with respect to the Horn types; and especially to Mr. W. F. Fiske, who most generouslj^ allowed me the use of his unpublished systematic notes on this genus. The genus Lasconotus was described in 1845 by Erichson, who based his description on an undescribed species from Mexico. He characterizes it as follows: Die Schienen an der Spitze ein wenig erweitert, und hier ausser den kleinen Enddornen noch mit feinen Dornehen besetzt. Die drei ersten Glieder der Ftisse gleich kurz. Fiihlerkeule dreigliedrig. Kor- perform und fast auch die Sculptur von Ditoma. Die Augen vollkom- men rund, ganz unter dem Seitenrande der Stirn liegend, welcher sich oberhalb derselben bis zum Scheitel fortsetzt. Die Spitze der Mandi- beln zweizahnig. Die Fiihlerrinnen auf der Unterseite des Kopfes undeutlich. Eine neue Art aus Mexico. •This paper was written by the author while in the employ <>f the Bureau ot Entomology, U. S. Department of Agriculture, under the direction of Dr. A. 1>. Hopkins, in charge of forestry insects. 26 PROCEEDINGS ENTOMOLOGICAL SOCIETY Dr. L,eConte in 1859 first recognized the genus in America and referred to it a new species, L. complex, which, being the species first described in the genus, should stand as its type- In 1866 Pascoe erected the genus Illestus, and referred to it a new species from Mexico, /. terrains Pasc. He separates this genus from Lasconotns mainly by the character of not having the side margins of the head covering the eyes. As pointed out by Dr. Horn (1878), this character is well marked in but a few species, becoming gradually less until it is scarcely traceable, and he concludes that Illestus is synonymous with Lasconotns. I have seen three specimens of /. terrenus Pasc. collected at Toluca, Mexico, and determined by Dr. Sharp. They are quite different from any Lasconotns known to me in the following readily observable characters. The anterior coxal cavities are apparently open, but in fact very narrowly closed behind, the tibiae scarcely everted externally and armed with a row of close-set spines instead of two prominent spines and several small ones, and the terminal segment of the maxillary palpi truncate, not at all rounded at the apex. In Pascoe's figure the antennas are shown as twelve-segmented. This is obviously an error in drawing; it is not observable in the specimens. The genus Lasconotns is quite readily divisible into well- marked groups, but there seems to be no sufficiently well- defined, constant structural character for separating them as distinct genera. The fore tibiae are usually everted externally, though in some species merely rounded, and always armed at the apex with two prominent spines. Several smaller spines extend from the outer to the inner apical angle, which is armed with two short, straight spurs. The anterior coxal cavities are closed behind the posterual epimera, broad behind the coxae. There is considerable range in size and general outline, though within the species these characters are very constant. The head, antennae, ventral surface, and especially the elytral and pronotal sculpture, furnish excellent and re- markably constant taxonomic characters. Very little is known concerning the exact habits of the species. They are usually found associated with various scolytids inhabiting coniferous trees. Principal among these are Pityophthorns (Tomicns}, and at least two species are found with Phlccosinus. Whether they are commensals or predaceous is not well known. The mouthparts, so far as I have examined, would indicate a predaceous habit, but even if so, whether they prey upon the scolytids themselves or the OF WASHINGTON, VOLUME XIV,^1912. 27 numerous other insects found in their galleries is still an open question. The larva is also so far unknown. In the following synopsis and descriptions thesutural inter- space in either elytron is considered as the first. The odd interspaces (1, 3, 5, 7, etc.) are always the more elevated, while the even (2, 4, 6, etc.) are frequently so flattened and unarmed as to appear obsolete, or nearly so, and in such in- stances the intervals between the costae have apparently a double row of punctures, which character is frequently men- tioned in former descriptions. In no instance are the even interspaces truly obsolete, however, and I have mentioned them throughout the descriptions. The locality given under each species is the t\pe locality. A full list of localities from which specimens were at hand is given at the end of the brief summary of each species follow- ing the synopsis: SYNOPSIS OF SPECIES.

Medium-sized, slender species, the pronotal structure very similar to Hnearis Crotch, and the elytral structure allied to flexuosust being, however, relatively more convex and the odd interspaces equally elevated throughout. I have seen but four specimens, one bred from spruce infested by Pityophthorus, from Grand Island, Michigan. Another taken by Mr. E. A. Schwarz on birch or alder at Marquette, Michigan, which Mr. Schwarz tells me is one of two taken by him at the same time. The other was given to Dr. LeConte.

A most remarkable and distinct species. It differs from every other in the genus by its peculiar elytral structure, hav- ing none of the interspaces elevated throughout, but instead the odd interspaces are broader, flattened, but interrupted at long distances by small tumid elevations bearing a dense tuft of whitish setae. A series of 15 specimens shows very little variation, except very slightly in size and a few examples have the anterior margins of the prothorax more broadly rounded.

This species and the preceding are peculiar in showing a tendency towards color markings on the elytra, which have the base and apex chestnut brown, the remainder dark piceous. Described from material "under" bark of sycamore or small forest tree at the Hot Springs in the Santa Inez Mountains (Crotch). There is very little variation in the series of four specimens examined, except in some the light markings of the elytra are more distinct. They were collected by beating young pine trees. If Crotch's specimens really came from be- neath the bark of sycamore it is remarkable. U.S. N. M.— California: Los Gatos (E. A. Schwarz). There are also four specimens of this species in the LeConte collection from California. Lasconotus apicalis Casey. 1890, p. 315. One of the larger species closely allied to z-cgrandif., but easily separated by the elytral structure and the shape of the prothorax as noted in the synopsis. In this species is seen the beginning of the union of interspaces 5 and 7, which are then prolonged as a single elevation toward the apex, a char- acter which reaches its extreme development in bitomoides, and also the reduction of interspace 3, which is most extreme in concaviis. There is some variation in this species in size and especially the amount of reduction of interspace 3 at the apex. In some specimens the smooth, unelevated area is of considerable extent, perhaps one-third the length of the inter space, while in others it is limited to one-fifth or one-sixth the length.

The distribution as given by Dr. Horn includes also la- queatus and subcostulatus. Lasconotus laqueatus LeConte. (Proc. Acad. Nat. Sci. Phila., 1866, p. 378.) This species is intermediate between pusillus and coiicurns, resembling the former in its somewhat elongate form and the hook-shaped elevations on anterior margin of prothorax, and the latter in the broad thoracic impressions and elytral struc- ture, except interspace 5 is not so strongly elevated, the strial punctures are more readily traceable, and the prothoracic im- pression narrower. There has been considerable confusion m regard to this species, subcostulatus, and pusillus. Dr. LeConte (1865) based his description on material from Dr. Elliott Coues, Arizona. The specimen now bearing the name label in the LeConte collection agrees precisely with the original descrip- tion, but in the same series are five other specimens labeled "Or." These specimens are all typically subcostulatus and totally different from the true laqueatus. In the Horn collec- tion I find that Dr. Horn has placed representatives of all these species under pusillus. Among them are 2 specimens of laqueatus, 1 from Pinal Mountains, Arizona, and the other from Montana; 7 specimens of subcostulatus, 2 of which are from Montana, 4 from Nevada, and 1 from Washington; and 2 specimens of pusillus, one uf which, bearing the name label, is from Georgia, the other from Florida. Dr. Horn's (1878) description of the unnamed specimens from Vancouver applies precisely to subcostulatus, as do also all the characters assigned by Col. Casey (1890) to laqueatus. The range of subcostulatus is northward and of /aquentus southward from southern Montana and southwestern South Dakota. I have specimens of both species from Colorado (Boulder), South Dakota (Black Hills), and Nebraska (Pine Ridge), and in the Horn collection from Montana. A series of 15 specimens showing some variation, more es- pecially in width. Found associated with scolytids under bark of Pinus ponderosa. 42 PROCEEDINGS ENTOMOLOGICAL SOCIETY Hopk. U.

A robust species showing the extreme development of the characters of the pusillns group. Interspace 1 is just visibly elevated, 3 elevated at base for about one-sixth its length, and 5 very strongly elevated from base to near apex; the strial punctures are just traceable. The prothoracic impression is very broad, with punctures fine and simple. A series of about 125 specimens. Commonly associated with scolytids in Pinus ponderosa and strobiformis . Hopk. U.

I have not seen a specimen, but it is apparently distinct from any of the species occurring in the United States. I quote the following from Grouvelle's description: Elongate, parallel, moderately convex, feebly shining, ferruginous, a little smoky; antennas, except the club, and the legs more reddish. Antennal club smoky, first segment narrower than the two following. Head granulate, wider than long at the level of the eyes, sides straight, converging anteriorly, anterior margin rounded, on the disc five impressions somewhat confluent, two anteriorly and three in line on the summit of the head. Prothorax granulate, the form of an in- verted trapezoid, just about as long as wide anteriorly, anterior mar- gin rounded, feebly sinuous at the extremities, sides nearly straight, finely margined and crenulate; base truncate, strongly excavated at the extremities; anterior angles feebly produced anteriorly, rounded, posterior almost right, well marked; at the middle of the disc a longi- tudinal furrow well marked anteriorly, and at each side of the furrow, two longitudinal carinaa; the internal less accentuated, divided anter- iorly and posteriorly into two short carinse, the external well marked, entire, flexuose. Scutellum puncture-iike. Elytra parallel, a little less than 3 times as long as wide, when taken together; each with three sensibly equal discoidal carinse, the first attaining the apical margin of the elytra, the two others united before attaining that margin, intervals between the carinas with two lines of large punc- tures. OF WASHINGTON, VOLUME XIV, 1912. 43 In the young decayed branches of Clnsict rosca and Atro- carpus. Guadeloupe, West Indies. From the description it seems somewhat allied to mcxicauus. If this species is a true Lascouotns it is remarkable that it should be found in the decaying branches and especially of the above-named trees, both of which are non-coniferous. Lasconotus sulcifer Sharp. 1894, p. 464. I have not seen a specimen. I quote the following from Dr. Sharp: Antennae with joints 3 to 8 quite small, the 3-jointed club large and abrupt. Head deeply and broadly impressed. Thorax longer than broad, finely margined at the sides, delicately punctate and pubescent, with a broad depression along the middle, limited on each side by an obtuse costa; these costse do not reach quite to the front margin, but they are each surrounded at the end by a slight curvate elevation; the extreme base of the thorax is strongly constricted, the true hind angles being thus concealed. The elytra have the shoulders promi- nent in front; they are broadly and deeply longitudinally depressed along the middle; the suture is scarcely costate in front, but is dis- tinctly so towards the apex; the first interstice is feebly costate, but only on the basal portion; the third interstice limits the broad de- pression and is strongly costate, and outside it there is also another costa, strongly raised and extending from the base to the apex; the intervals bear obscure serial punctures. Closely allied to L. pusillus Lee., but narrower, with the shoulders more prominent anteriorly, the elytral depression much more marked, and the costas more sharply elevated. We have received nearly 20 examples; they vary in color, some being brownish, but in other re- spects are very constant. Guatemala, San Geronimo (Champion). BIBLIOGRAPHY. 1845. ERICHSON, W. F.

Epicallima lucidella, new species. Labial palpi golden yellow. Antennae velvety black with silvery white tips; basal joint smooth without pecten. Face, head and thorax bronzy. The deep black ground-color of the forewings occupies but a small part of the wing as a margin on the base, along dorsum and around the apical edge to the brilliant deep golden-yellow area which occupies the larger costal half of the wing and sends a long process out towards the apex; at basal third is a narrow perpendicular black- edged metallic blue fascia, crossing the golden area and terminating in a pale yellow dorsal spot; on the cell are two pairs of paralel long- itudinal metallic blue streaks, all edged with black; on the middle of costa is a small pale yellow spot and at apical third is a similar pale costal dash. Cilia blackish with strong golden reflexions. Hind wings and abdomen black. Legs black, with the tips of the tarsi and the spurs silvery white. Alar expanse: 12-13 m.m. Habitat: Oak Station, Allegheny County, Pennsylvania. (Fred Marloff, collector.) Type: No. 14435, U. S. Nat. Mus. A brilliant species suggesting some of the European metallic species, but very different in pattern. Among the American species it conies nearest the smaller edithella Busck, from which, however, it is also amply differentiated in pattern. OF WASHINGTON, VOLUME XIV, 1912. 45 A READJUSTMENT OF MUSCOID NAMES. BY CHARLES H. T. TOWSEND. In these days dipterological nomenclature is getting a severe shaking up, and the Muscoidea come in for their share. The late resurrection of Meigen's 1800 paper, the recent discovery of various long-perpetuated nomenclatural errors as judged by the rules of the International Code, and the designation of certain genotypes by the late Mr. D. W, Coquillett call for a considerable amount of change in the names of muscoid genera, tribes, subfamilies, and in one notable case a change of family name. These changes are detailed below so far as they are apparent to me at this time. FAMILY PHASIID^. SUBFAMILY PHASIIN^. TRIBE PHASIINI. 1. Phasia Latr. (1804). Type: Syrphus hemipierus J. C. Fab., being the only species given by Latreille, as Thereva coleoptrata J. C. Fab., which is a synonym of the above, according to Bezzi and Stein. Syn.: Alophora'R. D. (1830), Girschner et al., which has the same type. Repr. habit: Subcutaneous oviposition (Pantel, Towns.). This compels dropping of Alophora, which will hereafter be known as Phasia, and likewise changes the meaning of the tribal and subfamily names derived from Phasia. 2. Hyalomyia R. D. (1830). Type: Phasia pitsil/a Meig., being designation by West- wood in 1840. Syn.: Parallophora Girsch. (1888), which has same type. Repr. habit: Unknown, but judged same as Phasia. This compels dropping- of I \irallophora, hereafter to be known as Hyalomyia. 3. Alophorella, g-en. nov. Type: Thereva obesa J. C. Fab., hereby designated. Syn.: Hyalomyia Girsch. (1888) et al. (nee. R. D.). Repr. habit.: Subcutaneous oviposition (Pantel). This and 2 call for a complete shift of the name J/va/t»)i\'ia, hereafter to carry a different meaning. 46 PROCEEDINGS ENTOMOLOGICAL SOCIETY SUBFAMILY ECTOPHASIIN^. TRIBE ECTOPHASIINI. 4. Ectophasia, gen. nov. Type: Syiphus{Thereva) crassipennis J. C. Pab. (female equals T. analis}. C. Fab.), hereby designated. Syn.; Phasia Auctt. (nee Latr.). Repr. habit. Host-oviposition of flat macrotype egg (Pantel et al.). This and 1 call for a complete shift of the name Phasia, which hereafter carries a totally different significance. NOTE. — Bezzi and Stein indicate Eratia occlusa R. D. (1863) as synonym of above genotype. The description appears to me incom- patible with specimens of crassipennis but conforms much better to those of Elomya lateralis Meig., whose abdominal spots show more- over a tendency toward the trigonal pattern. In the non-existence of Desvoidy's types and improbability of the above synonymy I do not consider the name Eratia available for use here. TRIBE RHODOGYNINI. 5. Rhodogyne Meig-. (1800). Type; Musca rotundata L., being the only species given by Meigen with his Gymnosoma (1803), which is manifestly the same genus, according to Hendel. Syn. : Gymnosoma Meig. (1803). Repr. habit: Host-oviposition of flat macrotype egg (Pan- tel, Towns, et al.). This calls for the dropping of Gymnosoma and its deriva- tive names, euphonious and long in use. FAMILY MUSCID^E. SUBFAMILY MESEMBRININ^. TRIBE MESEMBRININI. 6. Mesembrina Meig-. (1826). Type: Musca mcridiaua L., being designation by West- wood in 1840. Syn.: Metamesembrina Towns. (1908), which has same type. Repr. habit: Dung-larvipositiou, maggot apparently being carried through at least first stage in utero (Portchinski). 7. Hypodermodes, g-en. nov. J^ype: Musca mystacea L,., hereby designated. Syti. • Meser;ibri)ia Towns. (1908), (nee Meig.). Repr. habit: Dung-oviposition of few large eggs, the mag- got omitting its second stage (Portch.). This and 6 call for shift of Mesembrina from meaning given in Tax. Muse. Plies (1908). OF WASHINGTON, VOLUME XIV, 1912. 47 SUBFAMILY MUSCIN^B. TRIBE STOMOXYDINI. 8. Haematobia St. Farg. & Serv. (1828), R. D. (1830). Type: Conops irritant L,., being designation by Westwood in 1840. Syn.: Lyperosia Rdi. (1856-1862), which has same type. Repr, habit: Dung oviposition (Riley & Howard). Calls for dropping of Lyperosia and reinstatement in the economic literature of the generic name, H&matobia for the horn-fly. 9. Lyperosiops o-en. nov. Type: Stomoxys stimulans Meig., herebj' designated. Syn. : Hirmatolia B. B. et Auctt. system, (nee St. Farg. & Serv., nee. R. D., nee Auctt. econom.). This and 8 call for shift of H amatol i a from its former significance. FAMILY EXORISTID^. SUBFAMILY EXORISTIN^. TRIBE EXORISTINI. 10. Exorista Meig-. (1803). Type: Musca larvarum L,., being the only species. Syns.\ Jachina Auctt. (nee. Meig., nee. B. B ); Eu- tachina B. B. (1889-1893). Repr. habit: Host-oviposition of flat macrotype egg (Towns., Pantel, et al. ) This and 19 compel the dropping of the name Tachina and its derivatives, names which are probably the most familiar next to Musca in the whole superfamily. This, by far the largest family of the Muscoidea, will hereafter be known as the EXORISTID^ instead of the Tachiuidae. I hereby desig- nate Musca larrarnm Linne (Exorista, larvarum L. , Meig., 1803) the type of the family as the form most appropriate to discharge this function. Some may consider Musca grossa L. (Larvavora grossa L., Meig., 1800-1803) entitled to the honor, as being the original Tac&ina, but I believe that usage, propriety and still other considerations call more loudly for the above designation. NOTE. — In this connection a word may be said on the classification of Girschner, followed by Bezzi and Stein, which groups nearly all of the Muscoidea in the single family heretofore called Tachinidas and hereafter to be known as Exoristidte, the comparatively small remnant of Musca and its allies being thrown into the Anthomyiidae. From a 48 PROCEEDINGS ENTOMOLOGICAL SOCIETY purely nomenclatural point of view, if the genera Musca and An- thomyia are placed together in any group from family down, that group should clearly take its name from Musca. The genus Musca dates from the beginning of zoological nomenclature (1758). Antho- myia goes back only to 1803. Prom a taxonomic point of view, the consensus of anatom- ical and reproductive characters allies Musca and its kindred much more closely with Calliphora than with Anthomyia. It seems quite incompatible with evident relationships and phylogenies to separate Musca and its allies from the group TachinidcB of Girschner. SUBFAMILY PSEUDODEXIIN^. TRIBE MACQUARTIINI. 11. Paraporia, nom. nov. For Neaporia Towns. (1908) preocc. by Gorham in Coc- cinellidse (1897). Type: Aporia qiiadrimaculata Macq. Syns.: Aporia Macq. (1846) preocc.; Neaporia Towns, (nee. Gorham). Repr. habit.: Unknown, but judged larviposition near host. TRIBE OCYRTOSOMATINI. 12. Ocyrtosoma nom. nov. For Cyrtosoma B. B .(1891-1893), preocc. by Walker in 1829. Type; Cyrlosoma rufum B. B. Syn.: Cyrtosoma B. B. (nee Walk.). Repr. habit: Unknown, but judged larviposition near host. SUBFAMILY PHANIIN^. TRIBE CYLINDROMYIINI. 13. Cylindromyia Meig. (1803). Type: Musca brassicaria J. C. Fab., being the only species. Syn.: Ocyptera Latr. (1802-1805). Repr. habit: Host-larviposition (Towns). This change gives us new names for the long-familiar and euphonious Ocyptera and its derivatives, which must be dropped. NOTE. — Latreille appears to have given the generic name Ocyptera in 1802 with no species, but in 1804-1805 gave three species with it in- cluding the above, without designating a type. Curtis designated above genotype for Ocyptera in 1837. In the light of our present knowledge this tribe appears to form a natural division of the subfamily Phaniinae. I employ OF WASHINGTON, VOLUME XIV, 1912. 49 Phania as the type of the subfamily, following Brauer & von Bergeustamm, notwithstanding Robiueau-Desvoidy's earlier use of Ocyptera as the type of the group, since Phania is far more typical of the group as a whole and Ocyptera and its derivatives are now dropped. The subfamily is characterized in general by a great or considerable development of the female genitalia and presumably in most cases for the purpose of subcutaneous larviposition or perhaps oviposition originally. I place the Compsilurini here, and probably most if not all of the forms having the habit of subcutaneous larviposition will eventually be found to belong here. The group seems to bear a considerable affinity to the subfamily Phasiinse, which has a corresponding development of the female genitalia for the purpose of subcutaneous oviposition. The Phasiinae are in turn allied with the Conopidse on the same character, though much differentiated from them in others. I can not follow Bezzi and Stein in grouping Cylindrotnyia with the Pseudodexiine and Pyrrhosiine stocks. TRIBE EUTHERINI. 14. Imitomyia, nom. nov. For Himantostoma H. L,oew (1863), preocc. by Agassiz, in 1862. Type: Himantostoma sugens H. Lw., the only species. Syn.\ Himantostoma H. Lw. (nee Agassiz). Repr. habit: Unknown, but judged larviposition. SOBFAMILY ERYCIIN^B. TRIBE CROCUTINI. 15. Crocuta Meig-. (1800). Type: Mnsca geniculata DeG., being only species given by Meigen in 1803, as Stomoxys minuta J. C. Fab. (by error ap- pearing irritans), for his Siphona, which is the same genus according to Hendel. Syns.: Siphona Meig. (1803); Bucentes Latr. (1809). Repr. habit: Host-larviposition (Pantel et al.). This compels dropping the time-honored name Siphona and its derivatives. TRIBE ERYCIINI. 16. Huebneria R. D. (1847). Type: Tachina a /finis. Fall. , being designation by Robineau- Desvoidy in 1863 of Carcclia nigripes R. D., which is a syno- nym of the above genotype according to Bezzi and Stein. Syii.: Exorista Auctt. p. p. (nee Meig., nee B. B.). Repr. habit: Host-larviposition (Pantel). 50 PROCEEDINGS ENTOMOLOGICAL SOCIETY This resurrects one of Robineau-Desvoidy's generic names for a type whose reproductive status is known. NOTE. — The emendation of Hubneria to Huebneria is permissible under the rule of the International Code applying to manifest typo- graphical errors. TRIBE VORIINI. 17. Voria R. D. (1830). Type: Tachina ruralis Fall., being the only species. Syn.: Plagia Meig. (1838), for which Rondani designated in 1856 Jachina verticalis Meig., which is a synonym of above genotype according to Bezzi and Stein. Repr. habit: Host-larviposition (Pantel, Towns.). This drops Plagia and its derivatives, euphonious names. SUBFAMILY HYSTRICIIN^. TRIBE ERNESTIINI. 18. Ernestia R. D. (1830, Myod. p. 60). Type: Tachina rudis Fall., being the only species, as Ernestia microcera R. D., which is a synonym of the above genotype according to Bezzi and Stein. Syn.: Panzeria R. D. (1830, Myod. p. 68), (nee Meig., 1838), with Panzeria lateralis R. D. the only species, which is same as above genotype according to Bezzi and Stein. Repr. habit: L,eaf-larviposition (Towns., Pantel). This drops Panzeria and its deratives. TRIBE LARV^EVORINI. 19. Larvaevora Meig-. (1800). Type: Mnsca grossa L., being designation by Wachtl in 1894 for Tachina Meig., which is same genus according to Hendel. Syns.: Echinomvia Dumeril (1801-1823), Latr. (1805); Tachina Meig. (1803), B. B. (1889), (nee Auctt.). Repr. habit: L,eaf-larviposition (Towns., Pantel). This drops Echinomyia and its derivatives, euphonious and time-honored names. SUBFAMILY MASICERATIN^E. TRIBE STURMIINI. 20. Ugimyia Rdi. (1870). Type: Ugimyia sericarice Rdi., the only species. Syn.: Crossocosmia Mik (1890), with same genotype. Repr. habit: leaf-oviposition of microtype egg (Sasaki, Towns.). This drops Crossocosmia, which has been in use since 1890. OP WASHINGTON, VOLUME XIV, 1911'. 51 NOTE. — Bezzi and Stein call R<5ndani's names, both generic and specific, nomina nuda in effect, stating that they are without descrip- tion. This does not appear to be so. I have not access at this time to the original publication, but Mik's paper indicates that Rondani described the larva and puparium in a way which by the rules of the International Code is sufficient for the founding of either genus or species, provided only that the form referred to be unmistakably in- dicated. No one has the slightest doubt as to the identity of either the species or genus referred to by Rondani under the above binomial. If Rondani gave no description of any stage, then Cornalia's descrip- tion and figure, however poor, fulfils the provisions of the Code as such, since they carry no doubt of the identity of the form referred to. Hence the binomial holds in any event. It should be stated here that Meinert accepted Sasaki's ob- servations as to the leaf-oviposition habit at the time. It would appear that Rondani did so likewise in his founding of the new genus. TRIBE NEOPALINI. 21. Neopales Coq. (1910). New name for Pales R. D. (1830), (nee Meig., 1800), whose type is Tachina pavida Meig. (nee Illig. ), according to the synonymy given by Bezzi and Stein. Syn.\ Pales R. D. (nee Meig.), the name having been used by Meigen in 1800 for a tipulid. Repr. habit-. Leaf-oviposition of microtype egg (Towns.). This drops the name Pales from the Muscoidea. TRIBE EPIMASICERATINI. 22. Epimasicera, g-en. nov. Type: Tachina ivcsterniauni Zett., which Bezzi and Stein state equals Tachina in if is Meig., hereby designated. Syn.: Exorista Auctt. p. p. (nee Meig., nee B. B.). Rep. habit: L,eaf-oviposition of microtype egg (Pantel). This generically places another form whose reproductive habit we know. NOTE.— This species is not referable to any of Robineau-Desvoidy's genera, nor to any other previously erected genus so far as I can find, rauer and von Bergenstamm referred it (mitis Meig.) to their Parex- orista, which it cannot be. Eusisyropa blanda O. S., which they also referred to their Parexorista, I believe does not possess a micro- type egg, though a form with exceedingly similar external characters does possess such egg. Exorista fut.ilis O. S. possesses the microtype egg and was referred to Parexorista by Brauer and von Bergenstamm. It may belong to Epimasicera. TRIBE SALMACIINI. 23. Salmacia Mei-. (1800). Type: Musca capitata DeG., being designation by Curtis in 1835 for Gonia Meig. (1803), which is the same genus ac- cording to Hendel. 52 PROCEEDINGS ENTOMOLOGICAL SOCIETY Syn.: Gonia Meig. (1803). Repr. habit: L,eaf-oviposition of microtype egg (Towns., Pantel). This drops the familiar Gonia and its derivatives, euphoni- ous names in use for over a century. FAMILY DEXIID^. SUBFAMLY DEXIIN^;. TRIBE CALIRRHOINI. 24. Calirrhoe Meig-. (1800). Type: Stomoxys siberita J. C. Fab., being only species given with Pro sen a St. Farg. & Serv. (1828), which is same genus according to Hendel. Syn: Prosena St. Farg. & Serv. (1828). Repr. habit: Unknown, but judged larviposition in vicinity of host. This drops the long-familiar Prosena and its derivatives. FAMILY SARCOPHAGID^. SUBFAMILY MII/TOGRAMMIN^. TRIBE METOPIINI. 25. Neowinnertzia, nom. nov. For Winnertzia Schiner (1861), preocc. by Rondani in 1860. Type: Metopia mesomelcena H. Loew, hereby designated. Syn.: Winnertzia Sch. (nee Rdi.). Repr. habit: Unknown, but judged to be larviposition from double-sac uterus. NOTE. — I am aware that Bezzi and Stein recognize Winnertzia Sch. as a synonym of Mesomelxna Rdi. I here record my strong disap- proval of duplicate binomials. 26. Taxigramma Macq. (1849). Type: Miltogramma heteroneura Meig. , being on authority of Bezzi and Stein the same as Taxigramma pipiens Ferris (1852), the only species. Syn.: Heteropterina Macq. (1854), with above genotype as only species. Repr. habit: Unknown, but judged to be larviposition from double-sac uterus. This causes the abandonment of Heteropterina as a name. OF WASHINGTON, VOLUME XIV, 1912. 53 FAMILY SUBFAMILY TRIBE CESTRINI. 27. Cephalopsis .uen. nov. Type: CEstrus maaitalns Wied., hereby designated. Syn.: Cephalomyia Auct. (nee. Latr.). Repr. habit: L,arviposition in nostrils of ruminants (camels and buffalo in North Africa). This compels the dropping of Cephalomyia^ which has served as a generic name for nearly a century, in spite of its having had during most of that time the same genotype as CEstrus. NOTE.- Latreille gave the single species CEstrus ovis L. with his genus Cephalemya in 1818. Curtis designated the same species in 1826 as the type of CEstrus Linne (1758), apparently after all the original Linnean species of CEstrus had been abstracted to serve as types of the various genera, the greater part of them having been taken by Latreille. With these obsequies we bid adieu to the buried names, thanking Mr. Friedrich Hendel, of Vienna, for his part in the matter. PIURA, PERU, December jr, A NEW MEGALOPYGID FROM FRENCH GUIANA.

This should have been described in my paper on new species from the Guianas, published in Proceedings of the United States National Museum in 1905, but was omitted therefrom. 54 PROCEEDINGS ENTOMOLOGICAL SOCIETY DESCRIPTIONS OF THE LARV.E OF SOME LEPIDOPTERA FROM MEXICO BY HARRISON G. DYAR. The following larvae have been obtained by the Bureau of Entomology from Mr. W. Gugelmaun, bred by him at Mis- antla, State of Vera Cruz, Mexico. PAPILTONID^. Papilio belesis Bates. Larva. — Head rounded, slightly bilobed, shining black, with pale secondary hairs on the lower parts of the sides. Body subcylindrical, uniform; a subdorsal row of short papillae. Black; a large white dorsal saddle on joints 8 and 9, incised before, the points running down to the spiracle on joint 8; two rows of round red spots, stig- matally and subventrally. Food plant: Anona. NYMPHALIMS. Gynaecia dirce Linnaeus.

Uainpson includes this species in his list of "species omit- ted" with the note "? Chalcopasta, sect, with long upturned palpi." The type is before me, and I am of the opinion that the above brief remark aptly describes the relationship of the species. However, the effect of the presence of long palpi covering the front has been to entirely obliterate the frontal tubercular structure, the front being gently bulging, perfectly smooth, without any trace of the usual tubercle. This pre- vents the inclusion of the species in C/uilcopastn, in spite <>f the conformable I'acies and thoracic tufting, so that a new generic term must be employed. I propose RODRIGUESIA, for Dr. H. ( Htolengui, who originally indicated that the genus was new, but did not name it. The front legs are missing in the type, but presuming that a claw is present, the genus falls in the table on page 3 of vol. ix above mentioned, where it will form a new section between Xanthiria and Pseudoligia, "Frons with rounded prominence without corneous plate below it.'' 62 PROCEEDINGS ENTOMOLOGICAL SOCIETY / SOME NOTES ON INSECT ABUNDANCE IN TEXAS IN 1911. BY W. D. HUNTER, Bureau of Entomology, U.S. Dept. of Agriculture. These notes are not presented with the idea that the}" are of any special importance, hut it is believed that when similar notes are placed on record from different seasons that some light may possibly be thrown upon the laws which govern the sudden increase of species. In the case of injurious forms this may be of economic importance. Fluctuations in numbers of insects from season to season are apparently brought about primarily by enemies and by climatic conditions. The conditions in Texas in 1911 were very peculiar. The most striking feature was a marked de- ficiency in precipitation. Early in the spring the departure from the normal began and continued until about the first of August. So great was the effect of the drought that all vegetation in the State was affected. The corn crop was practically ruined and a similar disaster would have overtaken the cotton crop if it had not been for rains which came just before they would have been too late. Drought prevailed also during the season of 1910 and again in 1909. In fact, 1911 was the culmination of three years which were marked by extreme conditions of dryness. At the same time tempera- tures had occurred which theoretically would seem to be de- cidedly adverse to insects. One of the most remarkable occur- rences of this kind was the killing frost of October 29, 1910, which took place considerably in advance of the normal date. All these circumstances combined to cause a set of conditions which would have been supposed to have contributed to the scarcity of insects rather than to their abundance. On this account the notes to be presented may be of some special interest. It may be stated parenthetically that the cotton boll weevil was the onl}r important species which seems to have behaved as would have been expected. It was properly subjugated by the drought. The most conspicuous example of insect abundance in 1911 in Texas was that of Alabama argillacea^llon. This matter has been discussed elsewhere recently and will be passed over in this connection, more especially since it concerns a species which became abundant by an invasion of the country and not by sudden increase from a local source. Two enemies of the cotton worm assumed very large num- bers. One of these was Calosoma lugubre Say. This is not an uncommon insect in Texas and is found at the electric lights in some abundance during practically every season. OF WASHINGTON, VOLUME XIV, 1912. 63 The normal swarms at the lights, however, were exceedingly insignificant compared to the enormous numbers to he found in the fall of 1911. The abundance became most marked about October 8, but continued until the last days of that month. The maximum flight occurred on October 11. At that time, in places where strong arc lights were to be found, it would have been possible to have collected several barrels of the insects in a very short time. No other species of Calosoma were observed. Special observations were made to de- termine whether scrutator, u'il/coxi, or calidnm or other more or less common species were to be found, but without result. Undoubtedly the invasion of Calosoma was due to the great numbers of the cotton worms to be found in the fields at that time. The flight was general, as was shown by notes made at Victoria, Texas, by Mr. J. D. Mitchell and accounts which appeared in the newspapers. By the end of October the beetles had practically disappeared. The other enemy of the cotton worm which appeared in great numbers was Chalcis ovata. At the laboratory in Dallas during October and November a dozen specimens were some- times found upon a single window at one time. This is un- doubtedly another example of a rapid adjustment to an abundant host supply furnished by the increase in the num- bers of the cotton worm. J^ermes Jlaripes K. is not uncommon in Texas, where swarms occur ordinarily during the early part of the season. In 1911, however, the insect did not come into notice until about the middle of October. At that time much more than usual numbers were to be seen throughout the State. Gryllns pennsylntn/cus. — This .species occurs in great num- bers almost every season in Texas. The origin of the swarms is not known. In October, 1911, a very unusual flight began and the number of the insects present about the electric lights far surpassed the numbers seen at any time during the writer's more than ten years' experience in the State. Sp/ienop/ioms parrulus is a rather uncommon species which feeds upon the roots of Bermuda grass. Mr. W. D. Pierce made notes on the abundance of this species. During the early part of November, in a walk of four or five blocks from the laboratory at Dallas, he would frequently see from 50 to 100 adults. Only isolated specimens had ever been observed on previous occasions. This species was not at- tracted to lights. Athysanns exitiosiis Ball. This species was undoubtedly the most conspicuous during the season on account of its smarms about electric lights. The occurrence of this insect 64 PROCEEDINGS ENTOMOLOGICAL SOCIETY in large numbers is not uncommon, but during 1911 the numbers were far in excess of those usually seen. In Dallas, Texas, the swarms were so dense that some of the arc lights were extinguished and great inconvenience was caused in shops and homes on account of the ingress of the insects. Its small size allowed it to pass through the meshes of such screens as are used to keep out mosquitoes and house flies. To say that it was found in millions upon millions around lights both within and without buildings gives but an in- adequate idea of the incalculable numbers that were present. The invasion resulted in the closing of many shops as soon as darkness began. This began on September 18 and contin- ued until the 25th. After the latter date the numbers dropped off very rapidly. This species occurred in great numbers in many places outside of Texas. Prof. F. M. Webster informs the writer that swarms similar to those which occurred at Dallas were observed at Wellington, Kansas. At that place they appeared first on September 20. Along with the specimens of Athysanus cxHiosns were numerous other Hemiptera which Mr. 0. Heidemann has determined as indicated below. It will be noted that a con- siderable number of predatory forms occurred. Drcecucephala reticulata Ball. Mecidea longula Stal. Xerophlea viridis Ball. Reuteroscopus ornatus Rent. Pamera bilobata Say. Lygus approximates Reut. Julisus inultispinosus Ashm. Pceciloscytus basalis Reut. Harmostes reflexiilus Stal. This swarming attracted all the more attention by reason of the fact that it was simultaneous with the swarming of Calosoma lugubre and Alabama argillacea. In fact, there was such a conglomeration of species in such unsurpassed numbers of individuals that the incident will long be con- sidered historic by the residents of Texas. Records of the observation of enormous numbers of May flies are not uncommon in the literature. The only special interest of the present note is on account of the southern locality. Apparently the great flights which have been ob- served have taken place in much more northern localities, as along the St. Lawrence River and the Great Lakes. In May Mr. J. D. Mitchell observed remarkable multitudes of Hexagenia biUneata Say on the Guadalupe River below Vic- toria. This locality is at least a hundred miles south of the latitude of New Orleans. The occurrence is well described in Mr. Mitchell's notes, which read as follows : OF WASHINGTON, VOLUME XIV, 1912. 65 We ran into a swarm of May flies about ten miles above the junction of the Guadalupe and San Antonio rivers at about 3 p. m. They were clinging to the overhanging trees and as the boat would brush against the trees, distrubing the flies, clouds of them would flutter in the air. Great patches of them would fall into the river and thousands would light on the boat. This condition continued until we reached Tivoli, on the west bank of the river, in Kefugio County, where we tied up for the night. We sailed 11 or 12 miles by the river through the flies. The deck in places was slippery from stepping on their bodies and the sides and parts of the boat not swept by passing tree tops were covered with them, in places so close together as to obscure the color of the wood. Next morning, May 25, I arose at daylight and there appeared to be a heavy fog over the river. As daylight increased I observed that the fog was May flies. The wind was very light and they were all flying upstream. The swarm filled the river space from timber to timber and from water surface to about 8 feet high. The current threw the dead ones to the center of the river, where they formed a broad gray streak of drift. By 7 :30 a. m. the bulk of the swarm had lit on the overhanging trees, until they bent the limbs and obliterated the natural color of the tree trunks. These fragmentary notes are presented merely because they may be of use when taken in connection with others that may be presented. No adequate explanation of the great abundance that has been noted occurs to the writer. All that can be said is that they show a very remarkable ability on the part of insects to survive very adverse climatic vicissitudes. Mr. Knab stated that on a visit to South Carolina, in early August, he had observed a most remarkable abundance of the larva? of a buprestid leaf-miner, undoubtedly Brachys. It was at Swansea, 20 miles south of Columbia, in the sand region of the central part of the State. The predominating trees in that region are the oaks and these all showed an abundance of the brown blotch-mines on the leaves. So abundant were they that the aspect of the landscape was transformed, many of the trees appearing as if dying. On some trees every leaf was infested, and frequently there were two or three larvae in one leaf. He had sent a quantity of leaves containing larvae to the Bureau of Entomology, but they were not reared. Dr. Howard said that while the problem of the increase of the species mentioned after such remarkably dry seasons is a complicated one, it is obvious that such conditions of 66 PROCEEDINGS ENTOMOLOGICAL SOCIETY drought would favor the increase of such insects as are cus- tomarily greatly reduced in numbers by fungus diseases. He mentioned a rapid assembling of (. \tlosonui ivillco.xi at Huntsville, Alabama, in 1881, during an outbreak of the army worm, as resembling the instance mentioned by Mr. Hunter. He also said that Chalet's ovata is a general parasite of lepi- dopterous pupae and that its appearance in Texas last sum- mer was simply another assembling of individuals and con- centration of the whole in the cotton fields so abundantly stocked with those insects.

The species extends throughout tropical America, having been originally described by Druce from Ecuador and Peru. It has been taken in Costa Rica by Schaus and in Mexico (Misantla, May, August, November, 1910, June, 1911) by Miiller. The identification has been made by Mr. Schaus, who compared specimens in London. OF WASHINGTON, VOLUME XIV. 1912. 67 THE ANTS OF VICTORIA COUNTY, TEXAS. BY J. D. MITCHELL AND W. DWIGIIT PIERCI:, Bureau of Entomology, U. S. Dept. of Agriculture. The present paper is presented in pursuance of a plan to list the insects of Victoria County, which presents so many types of fauna and flora. The first paper of the series, entitled "The Weevils of Victoria County, Texas," published in volume xni, pages 45 to 62, of these Proceedings, gives a discussion of the peculiarities of the county, and it is therefore un- necessary to mention them again. The ants listed and dis- cussed below have almost entirely been determined by Dr. W. M. Wheeler, to whom we express our appreciation for his many kindnesses. Forty-six forms of ants are herewith listed, which gives the county one-third of the entire number of forms (140) listed for Texas by Dr. Wheeler in his recent volume on "Ants; Their Structure, Development, and Be- havior." We would call especial attention to the notes on the dispersion of several species by floods. PONERID^. Pachycondyla harpax Fabricius. This large black species nests on the ground under logs, between the bark and log, or in badly decayed logs. It IKIS been found in this county only in the moist sections, such as river bottoms and near the margin of lakes. The colonies are comparatively small, none having been found with more than 150 adults. A colony consisting of only 1 queen, 3 males, and 16 workers was found. Colonies found in February are generally hibernating, all of the ants being closely huddled and quiet. Winged ants have been found February 2, but the first immature stages were found early in March. The pupa? are protected by a cocoon. Workers have been taken foraging under cow chips (Alitchell). Ponera trigona (Mayr) opacior Ford. Several wrorkers were found in the roots of Chenopodium on March 29, 1909 (Mitchell). Two colonies have been taken in February on (larcitas ('reek in cavities in the ground under sticks.

This elongate brown species has been frequently taken in this county between February •'! and March l(i, and invari- 68 PROCEEDINGS ENTOMOLOGICAL SOCIETY ably under logs in the river bottoms. On February 26 ten ants were found in a bunch with a single pupa (Mitchell). Specimens have also been taken November 19 (F. C. Pratt). Odontomachus clarus Roger. This species was taken in an adjoining county on June 19, 1907, on Anthem is arvensis (Mitchell). The species has been found resting in the ground. Ectatomma tuberculatum Olivier. This ant was colonized in Victoria County from Guatemala in the years 1904, 1905, 1906. The colonies were of rather small size. Their foraging habits were very closely watched. They are very fond of honeydew and nectar, but also require insect food. The short-sightedness and feeble sensory powers render an abundance of insect food necessary to furnish the wants of the colony for solid food. At Victoria in July they were most active about 8 o'clock in the morning and from 3 to 7 in the afternoon. It was noticed that while consider- able food was stored in food chambers, the small native ants generally made away with most of it. The distance foraged was seldom over 10 feet. The ants were observed to kill boll weevils (Anthonomns grand is), caterpillars, and other ants. Whenever individuals of Pogoriomyrmex barbatus encountered one of the strangers there was a struggle and the native ant lay dead, but in the end the cooperation of Po- gonomyrmex prevailed over the individual prowess of Ecta- toituiia, which seems to have no instinct prompting mutual help. All attempts to establish this species firmly appear to have ended disastrously (Pierce). DORYLID.E. Eciton coecum Latreille. This species was found nesting March 4, 1910, in alluvial soil. The workers were of three sizes. Males have been taken many times at lights of houses and camp fires in this and surrounding counties (Mitchell). Eciton (Acamatus) opacithorax Emery. A large aggressive colony was taken under a dead log, April 14, 1909 (Mitchell). Eciton (Acamatus) harrisi Haldeman. This species was collected at Victoria, Texas, September 18, 1904.

These peculiar looking ants are always found near water courses and lakes. The colonies are usually small. They have never been seen with more than 30 in a colony. On May 25, 1909, a colony consisting of queens, males, workers, pupae, and larvae was found in a dead limb of a live-oak tree. On May 17, 1909, a similar colony was found with winged queen and male, workers, and male and female pupae. On October 25, 1909, a colony consisting of only 3 workers, 4 larvae, and 2 pupae was found in a dead live-oak twig. On March 4, 1910, a single ant was taken on a willow tree. March 3, 1911, two colonies were found in abandoned live-oak twig galls of Amphibolips. Workers have been taken on grapevine De- cember 19, 1910, and on mistletoe January 16, 1911. A colony consisting of queen, 3 pupae, and 3 larvae of different sizes was found in an empty blackjack acorn on the ground October 25, 1911 (Mitchell). Pseudomyrma pallida F. Smith. A colony of this yellow ant was found in a stem of Iva ciliata January 17, 1910 (Mitchell). Pseudomyrma flavidula F. Smith. This species is usually found in the neighborhood of water courses and lakes. The colonies are sometimes large. On December 15, 1908, a colony consisting of winged forms, workers, and larvae was found in a stem of Solidago. A nest was found in the stem of a dead Xanthiii-m January 16, 1909. On March 19, 1909, a colony of females, workers, larvae, and eggs was found in a stem of Iva ciliata. On January 28, 1910, a colony was taken in the stem of Ambrosia trifida, and in another large stem of the same species several connected colonies were found — there were 3 or 4 queens. A colony was found in a stem of h'ii ciliata February 12, 1910, and on February 19 one was found in Ambrosia. March 16, 1911, in a stem of Iva ciliata, a queen, 30 workers, and 61 immature stages were found (Mitchell). Psudomyrma brunnea F. Smith. A small colony of workers and larvae was found in a dead twig March 6, 1909. A worker was taken on mistletoe January 16, 1911 (Mitchell). 70 PROCEEDINGS ENTOMOLOGICAL SOCIETY Monomorium pharaonis Linnaeus. This introduced ant has not only been a bad pest in the house, but has also been found nesting in the woods under bark of pecan and elm logs and also under the bark of a live pecan tree (Mitchell). This species has been taken attacking the immature stages of the boll weevil (W. W. Yothers). Monomorium carbonarium F. Smith. Workers of this species were three times found in buds of Callirrhoe involu crata devouring larvae of Anthonomiis fukiis, May 24, 1907. They were also found in the blooms at pollen. On February 24, 1909, a colony including queens, workers, and larvae was found under bark of a dead elm log. A small lot of ants was taken March 6, 1909, from cells of Ar&cerns fasciculatus in dried cornstalks. A nest with a few immature stages was located in a decaying ash stump, March 27, 1909 (Mitchell). Monomorium minimum Buckley. Under the bark of a willow log on March 12, 1911, an enormous colony was uncovered. This embraced practi- cally the entire upper surface of the log for a distance of 33 feet. The entire space was connected by many galleries' and every 3 to 6 inches was a queen with young. Four queens were observed in one batch of immature stages. On May 22, 1909, a colony with 7 queens was found under the bark of a dead sycamore (Mitchell). Solenopsis geminata Fabricius. The fire ant is very common in Victoria County. It nests in logs, stumps, and in the open ground and frequently in- vades dwellings. It has been taken as an enemy of the boll weevil by W. E. Hinds, July 22, 1907. It was taken in abun- dance on mistletoe ( Phoradendron flavescens) January 16,191 1 (Mitchell). Solenopsis geminata (Fabricius) diabola Wheeler. This is the commonest variety of this ant at Victoria. Solenopsis texana Emery. This tiny species is usually found in the wooded country, as the following records show. On February 24, 1909, a colony was found under bark of a dead elm log. It contained 2 queens, many workers, pupae, and larva1 . On April 19 colonies were found in a rotting pecan log and in tree fungus; on April 26 in elm stumps; on May 20 and 22 under bark of pecan trees, each colony with one or more queens (Mitchell). OF WASHINGTON, VOLUME XIV, 1912. 71 Solenopsis up. A very tiny species of ant has been taken quite frequently nesting in dead pecan twigs and under bark. Pheidole dentata Mayr. Colonies of this ant are very large and when disturbed they swarm out in large numbers, seeking the intruder and making it interesting for anyone desiring to make close ob- servations. In defending their nests they are only surpassed by the giants Neoponera villosa. They build in dead wood, in the ground under logs, chunks, and stones, and occasionally among the roots of vegetation. In April, 1897, the senior writer observed a colony in high water floating down the Guadelupe River. They were on a chunk of dead wood, which was almost submerged. The ants were collected on- the upper part in two clusters, with a string of workers connecting them. One bunch protected the queen, the other the immature stages. They fought savagely to protect both queen and young. On February 16, 1909, a colony was taken from a rotting log in the river bottoms. Other colonies were found in similar places March 20 and April 14. On May 22, 1909, a large colony was found in a pecan log. Many pupse were in the act of molting to adults. When the nest was dis- turbed the workers and soldiers did not show their usual aggressiveness, but gave their attention to the unfortunate immature adults, caring for them as they would for larvae or pupa?

They were very fierce (Mitchell). 72 PROCEEDINGS ENTOMOLOGICAL SOCIETY Pogonomyrmex barbatus (F. Smith) molefaciens Buckley. This common hillock ant occurs all over Victoria County. The majority of the colonies clear a space aroung the hole from 3 to 6 feet in diameter. Their runways are also bare of vegetation and may extend 50 feet or more; one pathway was an inch wide and extended 125 feet. The ants cut off the plants in their way and remove the debris to the side. On sunny days one can always see a steady stream of foragers on these paths, those going homeward carrying either seed or insects. Numerous large caterpillars and a cricket were seen carried into the nests. Near the hole there is usually a pile of seed hulls, which are brought out of the nest about as fast as seed are taken in. As rainy weather approaches the foragers all hurry home and no others go out. Several times remains of this ant were found in the excrement of the horned toad (Phrynosoma cornutd), and one colony was absolutely exterminated before the enemy left it (Pierce). The males and females swarm out of the nests in May and June, usually just after a rain, covering the ground for many feet around the nest. Here the mating takes place, after which the females fly. When they alight, they cast their wings and begin dig- ging a cell for a new colony. The males are driven away by the workers or killed if they persist in returning. The swarm- ing is a harvest for the birds. A colony of nesting jackdaws was observed to clean up an entire swarm in a short time. Woodpeckers destroy a great many. Doves have been credited with feeding on this ant, since they have been often seen picking on the ant hillocks. The senior writer has killed several doves on the hillocks but has found no ants in their crops. The doves were probably collecting the fine gravel brought up by the ants. The workers are fierce in defending their home, never running from an enemy. Their sting is very painful, but not dangerous. Daring heavy rains or floods the ants collect on top of the hillock and await the falling of the water. They have been observed several times floating in a mass on the water anchored to weed stems, the most important observations of this kind having been made during the great storm of September 15 to 17, 1875, which drowned thousands of quail, grouse, rabbits, and skunks. Leptothorax sp. On April 17, 1908, a complete colony was found in the hol- lowed interior of a green fruit of Opuntia.

Atta texana Buckley. On July 23, 1904, a colony of this leaf-cutter ant was visited, which was doing considerable damage to beans. They were not injuring the leaves, but were cutting portions of the bean- pod hulls. A very large caste were guarding the entrance to the holes, a slightly smaller caste were doing the cutting, the next caste were picking up the cut bits and carrying them in, and two smaller castes were carrying out dirt (Pierce). In May, 1892, a large number of winged forms passed from north to south on Main street, Victoria. The swarm was about 30 feet long and over 8 feet wide. They traveled south in a zigzag path for two blocks and then began flying away singly. On one occasion a large mass of these ants was observed floating in the Guadelupe River. The mass was about 2 feet across, and the ants were clinging to each other; They had drifted into quiet water and were held by debris (Mitchell). DOLICHODERID^. Dorymyrmex pyramicus Roger.

There were many hundreds of ants, and from t he first blow to the last they were busy, each class to its own work. The large, heavy-jawed individuals, comprising about two-lhirds of the colony, came out to fight. They were active and aggressive, spreading out 3 feet from the log in every direction, seeking their enemy. In defense they were far inferior to Neoponera villosa. The larvse were very few and were cared for by small, slender workers. February 15, 1910, a colony was found in the center of a decayed willow tree, clustered in several small connected cells, being packed closely for hibernation. The colony consisted of four winged forms, 45 nurses, 61 medium-sized workers, and 74 large foragers. This colony was shipped to Dallas for observation (Mitchell). The winged forms all died en route. The remain- der were placed in a breeding-cage. On May 2 a cluster of eggs was noticed surrounded by workers. The eggs hatched in due time, but the larvae developed very slowly. They were separated into groups June 3. July 9 a cocoon was observed inclosing one of the largest larva. July 15 two more cocoons were formed. July 29 a winged male hatched out (H. Pinkus).

In discussing Mr. Pierce's paper, Mr. McAtee called atten- tion to the fact that Mr. Pierce's examinations with negative results of the stomachs of mourning doves which were sup- posed to be eating ants confirmed previous findings regarding this bird. Mr. Schwarz had examined about 220 stomachs without finding any insects, and the Biological Survey of the United States Department of Agriculture had examined more than 250 with almost the same result. The most inter- esting animal remains in dove stomachs were apparently weathered segments of millipeds, which indoubtedly were parts of long-dead animals, taken perhaps in lieu of gravel. This called to mind another observation which definitely proves that dead insects are sometimes taken, and which furthermore has bearing on the habits of ants. Two specimens of Serial taken from the stomach of a roadrunner (Geococcyx California)! us} collected at Seaside, California, had the weath- ered appearance noted above and were in fact mere empty hulks. In the abdominal cavity of one specimen were eight Momorum muriatum and in the other two. These little ants were in perfect condition, which proves they were in the bodies of the beetles when swallowed by the bird. OF WASHINGTON, VOLUME XIV, 1912. 77 SOME NOTES ON THE TICK ORNITHODOROS TALAJE GUERIN. BY ALLAN H. JENNINGS. In 1910, while connected with the laboratory of Ancon Hospital at Ancon, Panama Canal Zone, I made a series of observations upon the domestic rats of Panama and their ectoparasites, these observations being continued daily for seven months. During that time about 2,300 rats were examined. The material was received alive, chiefly from the health officer of the city of Panama, though a small number of animals was sent from Colon, together with a few from the Canal Zone. The species received were, in the order of their abundance, A fits norvegicus (brown rat), Afits rattns (black rat), A fits alexandrinus (roof rat), and Mus ninsciiliis (house mouse). When chloroformed and examined for parasites, many rats were found to be infested by large numbers of the larval stage of an argasid tick which was subsequently identified by Mr. Nathan Banks as Oniithodoros talaje. Though taken from all three of the species of rats, the brown rat was by far the most heavily infested and of the many hundreds of the ticks examined but a small percentage was taken upon the other forms, none occurring upon the house mouse. It should be noted that the nesting habits of the brown rat are different from those of the black and roof species in that the brown rat is essentially a burrowing animal, while the nests of the other species are usually above ground, in the walls of houses and even in trees. Brown rats from Colon were also found to harbor the ticks, though the proportion of animals infested and the degree of infestation was less than among those from the city of Pan- ama. However, the number received from the former city was not great enough to warrant the formation of definite conclusions as to their abundance. But that ( Iruithodoros. talaje occurs on the Atlantic side of the Isthmus is certain The larvae were attache'! to almost all parts of the bodies of the animals, but showed a marked preference for 1 In- posterior portion of the dorsum. A peculiarity regarding the points of attachment was that in almost all infested animals, especially in those in which the infestation was heavy, a considerable portion of the parasites could have IK-CD easily reached by the teeth of the host, yet they \\ere not destroyed. Thus it would seem that a cetrain toleration for them has been established in the rodent. In many cases in which gross infestation of the dorsum occurred, the irritation caused by 78 PROCEEDINGS ENTOMOLOGICAL SOCIETY the parasites was so great that a pronounced dermatitis had been set up. This occurred oftenest in fully adult and old individuals in which the coat was coarse and scanty. With the exception of two nymphs taken from one Mns norvegicus, all of about 3000 of the ticks examined were larvae, it being evidently the habit of the species to drop from the rodent host before molting into the nymphal stage. A number of full-grown larvae which survived anaesthesia were preserved alive, and though attempts to induce them to reattach to white rats failed, they molted, and as nymphs survived without food for about five months, during which period at least one molt occurred. The feeding habits of the nymph are not known to me, but in Panama, as is known to be the case elsewhere, the adult attacks man, adopting the habits of the bedbug. Whether the rat shares with man the attentions of the adult tick I do not know, though this is indicated. From the abundance of the larvae upon Panama rats, the adults should be numerous in the houses of the poorer classes in that city, but efforts to secure specimens were unavailing. It is probable that the inhabitants do not distinguish accurately between the species and Cimex lectnlarius, specimens of which latter were invariably brought when "mamones," the native name for this tick, were asked for and promised by the col- lectors. They occur in villages of the interior, Dr. Darling having collected them at Chorera, where the people showed evidences of their attacks. Their abundance there is probably less than in Panama if the numbers of the larvae observed in the latter place is a sufficient indication. This may be due to the fact that Mns nittus is the common house rat of the country districts, while the brown rat prevails in the urban portions of the city of Panama. This hypothesis implies that the preference manifested by the tick for the brown rat is constant and not due to local conditions, further observations being necessary to establish the fact. I believe this to be the first record of the domestic rat serving as host for the larvae of Ornithodoros talaje. The double role as parasite of rodent and man played by this species, suggests the .possibility of disease transmission from one to the other of these hosts. OF WASHINGTON, VOLUME XIV, 1912. 79 THE CLASSIFICATION OF THE ALEYRODID/E. Messrs. A. L. Quaintajice and A. C. Baker presented a paper dealing with the principles of classification of the Aleyro- didae which they had determined as a result of the study of the forms thus far known. A new subfamily was established and several new genera and species described. The paper treats of all known members of the family, except those belonging to Aleyrodes, which will be made the subject of a subsequent publication. The paper in full will be issued in the Technical Series of bulletins of the Bureau of Entomology, United States Department of Agriculture. Under the heading "Notes and Exhibition of Specimens," Mr. Knab spoke of the dependence of disease transmission by blood-sucking insects upon habits. This seems to have been overlooked by investigators of this subject and many insects have been suspected which, from the present view- point, must be eliminated. In order to be a potential trans- mitter of human disease an insect must be closely associated with man and normally have opportunity to suck his blood repeatedly. It is not sufficient that occasional specimens bite man, as is the case with forest mosquitoes. Although a person may be bitten by a large number of such mosquitoes, the chances that any of these mosquitoes survive to develop the parasites in question, and then find opportunity to bite and infect another person, are altogether too remote. On this principle Simuliidse and Tabanidse, as well as the numerous sylvan mosquitoes, can be confidently eliminated. More- over, most of these insects are active only during a limited season and consequently there is too great an interval during which no transmission could occur. The truth is that all insects that have been found to be transmitters of disease are more or less closely associated with man and habitually suck his blood. This has long been recognized in the case of the two house-mosquitoes of the tropics, the one (Acdes ca/opn*) being the intermediary host of the yellow fever organism, the other ( ( 'tt/c.v quinquefascia- 80 PROCEEDINGS ENTOMOLOGICAL SOCIETY tus) of those of filariasis and dengue fever. It is only through a combination of circumstances that these insects are effective transmitters. These conditions are: the association with man and a predilection for his blood, abundance, comparative lon- gevity, and consequent repetition of blood-meals at intervals, and finally, practically continuous breeding, so that individuals are always present to act as intermediary hosts of the parasites. Thus the chain in the life-cycle of the parasite is never broken. The relation of the different species of Anopheles to the transmission of malaria seems never to have been considered in this light. It was, however, brought out in an interesting manner in a paper on mosquito-control in the Panama Canal Zone, read by Mr. Jennings at the recent meeting of the Asso- ciation of Economic Entomologists. Mr. Jennings pointed out that the different species of A nopheles of that region have widely different habits. Investigation of the role of these differ- ent species in the transmission of malaria, by inducing them to suck the blood of malaria-carriers, showed that the species {Anopheles, albimanus] which throve most about settlements, and was most persistent in entering houses and obtaining blood, was the principal factor in malaria transmission, no less than 70 per cent of this species developing the parasites. Mr. Knab said that in commenting on Mr. Jennings's paper he pointed out these facts and in addition gave further evi- dence of the close association of A. albimanus with man, im- parted to him by Mr. Jennings in conversation. It appears that this species is absent from those parts of the upper Chagres River which are uninhabited and that the reason is that this mosquito not only prefers, but probably needs, human blood. Mr. Knab said that his remarks before the Economic Entomologists had been met by the assertion of Mr. Schwarz that the absence of .4. albimanus from the upper Chagres had nothing to do with the absence of man, b;'twas due wholly to the lack of suitable breeding-places. Mr. Knab stated that Mr. Schwarz was certainly in error and that there were plenty of suitable habitats for the larvae of A. albimanus, at least in parts of the uninhabited region under consideration. OF WASHINGTON, VOLUME XIV, 1912. 81 Dr. Howard called attention to the paper by Dr. Lutz of Brazil, on forest mosquitoes and forest malaria, which appeared to contradict Mr. Knab's statements. Mr. Knab replied that he had just discussed this paper from his present viewpoint with Dr. Dyar. They had reached the conclusion that Dr. Lutz had misinterpreted the facts. Dr. Lutz's observations were made in the state of Sao Paulo during the construction of the railroad from the coast to the capital. The first part of the route was through the moist and heavily forested slope from the table-land to the coast, and while at work here a large part of the laborers were af- flicted with malaria. Lutz searched for the transmitting Anopheles, but could find no breeding-places upon the steep slopes. Finally he determined that a single species of Anoph- eles (cruzii] was abundant in the region and that this bred in the water of epiphytic bromeliads. To this species he at- tributed the outbreak of malaria. It would seem now that the Anopheles found by Dr. Lutz probably had nothing to do with the outbreak of malaria among the construction gang. It is a well-known fact that in the tropics most persons apparently in good health have latent malaria. When such an individual comes under some physical strain, such as overexertion, fatigue, or exposure, the disease manifests itself. It therefore seems highly probable that the men observed by Lutz already harbored malaria in a latent form when they came into the region and that the exertion and exposure incident to the work caused the irruption of the disease. Mr. Busck stated that he had investigated the mosquitoes of the upper Chagres in 1907 and could confirm Mr. Knab's statements with reference to Anopheles albimanus. He found that on the uninhabited parts of the Chagres Anopheles eiseni was the prevalent species, while A. albimanus was not found by him there, and this absence was not due to lack of breeding facilities. He expressed the opinion that at points still farther up on the Chagres, where there are settlements, at San Juan for example, .1. albimanus would be found. 82 PROCEEDINGS ENTOMOLOGICAL SOCIETY MEETING OF FEBRUARY 1, 1912.

Mr. Rohwer stated that he had recently received a com- munication from the Philadelphia Academy of Natural Sciences extending a very cordial invitation to the members of the Entomological Society of Washington to attend their centen- nial meetings March 19, 20, and 21. Mr. Schwarz moved that Mr. Viereck be elected a delegate to represent the Ento- mological Society of Washington at these meetings. Carried. President Quaintance suggested that a memorial in the nature of a written communication be sent to the Philadelphia Academy of Natural Sciences. Dr. Howard moved that this matter be referred to the Executive Committee with power to act. Carried. The names of E. B. Blakesley and H. E. Smith, of the Bureau of Entomology, were proposed for active membership and in accordance with the rules were laid over until the next meet- ing. The name of P. H. Timberlake, Whittier, California, was proposed for corresponding membership and referred to the Executive Committee. Dr. Howard stated that it was customary among the affiliated Societies of the Washington Academy of Sciences to nominate their presiding officer for the ensuing year to represent the organization as Vice President, and fearing that the vote of the Society had been misplaced he begged to re- sign and nominated President Quaintance. On a vote Presi- dent Quaintance was regularly nominated to represent the OF WASHINGTON, VOLUME XIV, 1912. 83 Society as a Vice President of the Washington Academy of Sciences. The first paper of the evening, "New Microlepidoptera from Mexico," by August Busck, was read by title. The second paper was "Observations on the Codling Moth," by A. G. Hammar. The last paper was "An Old Question," by S. A. Rohwer. NEW MICROLEPIDOPTERA FROM MEXICO. BY AUGUST BUSCK. The following new species are part of extensive collections of Lepidoptera, received from Mr. R. Miiller in Mexico City. The species here described are not represented in the ma- terial treated in Lord Walsingham's part of the Biologia Centrali- Americana, now soon to be concluded, and are published now so as to be available for the final list of species in that paper. Genus METOPLEURA, new (Gelechiidte) Type: M. potosi Busck. Second joint of labial palpi very long, porrected, but slightly curved up- ward, clothed with compressed scales, which form somewhat roughened sharp anterior and posterior edges; terminal joint one-third as long as second, compressed, pointed. Maxilary palpi rudimentary. Tongue well developed, scaled, spiraled. Antennae simple, shorter than the fore wings. Fore wings ample, elongate; costa and dorsum straight, parallel; apex produced, pointed; termen oblique, slightly sinuate below apex. 11 veins; 7 and 8 coincident, to costa; rest separate; 2 from before apical third of the cell; 3 and 4 approximate from the end of the cell; 11 from the middle of the cell; 6, 7,8, 9, and 10 equidistant; 1 furcate at base. Hind wings much broader that the fore wings; costa and dorsum nearly straight; apex bluntly pointed; termen evenly rounded, with a slight sin- uation below apex. 8 veins; 3 and 4 closely approximate, nearly connate; 6 and 7 approximate; 5 cubital; S anastomosing with radius before the middle of the cell. Posterior tibiae nearly smooth, but somewhat rough- scaled above. Allied to and rather similar in general habitus to Ac rot y pin Walsingham, but differing in the palpi, and in having veins 7 and 8 coincident in the fore wings. In my synoptic generic table this genus runs to I larpu»idia Ragcnot, which is unknown to me in nature, but which would seem to agree with the present genus in venation; the very different labial palpi with the short terminal joint will suf- ficiently differentiate the present genus. 84 PROCEEDINGS ENTOMOLOGICAL SOCIETY Metopleura potosi, new species. Labial palpi light straw-colored, speckled with fuscous. Antennae light fuscous. Face, head, and throax light ochreous. Fore wings ochreous, longitudinally streaked along the vein, with lighter whitish ochreous. From near the base of costa runs an outwardly oblique blackish fuscous streak across half the wing and at apical fourth on the dorsal side is found a poorly denned blackish streak, parallel with termen; both of these mark- ings are easily rubbed off and the majority of the long series before me shows only traces of them. There is a series of poorly denned dark marginal dots around apical and terminal edge. Cilia ocherous mixed with dark fuscous. Hind wings shining, dark fuscous with a light ochreous marginal line on the base of the cilia. Abdomen ochreous fuscous. Legs ochreous speckled with fuscous. Alar expanse, 30 to 36 mm. Habitat: Cerritos, San Luis Potosi, Mexico, August. R. Miiller, collector. Type: No. 14523, U. S. National Museum. Cotypes in British Museum. Ethmia proximella, new species. Labial palpi white; second joint dusted with black exteriorly. Face and head white. Thorax white with four bluish-black dashes, two ante- riorly, two posteriorly. Fore wings white with a broad black costal edging; widest on the middle of the wing; the line between this black costal part and the white dorsal part of the wing is zigzagged and irregular. On the white dorsal part of the wing are a number of round bluish-black dots, of which one is near base, one on the middle of the cell and one on the fold obliquely below; then come three dots in an oblique row, the first on the middle of dorsum, the last on the lower edge of the cell; after these there is further out another oblique row of three equidistant dots and parallel with the terminal edge is an irregular double row of less clearly defined dots. The extreme terminal edge golden yellow. Cilia white with dusky tips. Hind wings smoky white, in the male with a large yel- lowish costal tuft. Abdomen dark fuscous with yellow tip. Legs ochreous white; tarsi with strong black annulations. Alar expanses, 17 to 20 mm. Habitat: Tehuacan, Mexico. R. Miiller, collector. Type: No. 14524, U. S. National Museum. Cotype in British Museum. This species was sent me by Mr. Miiller as Ethmia mulleri Busck, which it resembles in size and ornamentation; it is, however, easily distinguished by the more numerous black dots on the fore wings (in mttUeri there are only six in three pairs), by the lack of the well-defined terminal series of black dots, and by the presence of the golden terminal line. OF WASHINGTON, VOLUME XIV, 1912. 85 The species is even more similar to E. bittenella Busck, which is best distinguished from it by the irregularity of the form of the black dots as well as their quite different positions. Ethmia abdominella, new species. Labial palpi white, dusted and barred with black. Face leaden-white with a large black dot on the vertex and head. Thorax dirty leaden- white, with six black dots. Forewings with costal half dark blackish brown with scattered black longitudinal streaks and with irregular black prominences into the lighter lead-colored dorsal half, which contains three independent black spots. A series of black dots along apical and terminal margin. Cilia dirty white. Hind wings whitish, semitransparent on basal half, with smoky tip and terminal edge. Abdomen golden yellow. Legs dirty white; tarsal joints with indistinct black annulations. Alar expanse, 30 mm. Habitat: Tehuacan, Mexico. R. Miiller, collector. Type: No. 14525, U. S. National Museum. Nearest to E. arctostaphylclla Walsingham, but easily differentiated by its larger size and darker head and thorax, also by its additional black spots in the light dorsal portion of the wing. Genus CALANTIGA Zeller. Type: albella Zeller. This genus must, I believe, be included in the family Hemerophilidse. The type, Calantica albella Zeller, has the following generic characters : Antennae less than the length of the fore wings, simple. Labial palpi long, thin, weak, upturned, reaching vertex; terminal joint nearly as long as second, tolerably pointed. Fore wings broad, with slightly arched costa, pointed apex, well-defined tornus, and slightly sinuate termen; 12 veins, all separate; 7 to termen; one of my slides shows veins 2 and 3 stalked; in another they are closely approximate. Hind wings are broad as the fore wings; 8 veins; 3 and 4 stalked; 6 and 7 parallel. In this connection I would call attention to the genus Herrickia Staudinger, which in the European check-lists has been placed in the Hyponomeutidse close to Calantica Zeller; if, however, the single specimen of the type of this genus, excelsella Staudinger, in the U. S. National Museum is authentic, as it presumably is, determined and labele.d by O. Hoffman, this genus belongs to the (Ecophoridae and agrees well with my later genus Fabiola in venation and oral charac- ters. As the general habitus is rather different, I prefer not to make Fabiola a synonym on the evidence of a single specimen, but the genus should be kept in mind in the future study of the family (Ecophoridse. 86 PROCEEDINGS ENTOMOLOGICAL SOCIETY Calantica argentea, new species. Labial palpi ochreous white. Face, head, and thorax silvery white. Fore wings shiny silvery white with a single short dark-brown dash on the lower corner of the cell; in some specimens with a few single scattered brown scales on the outer part of the wing. Cilia white. Hind wings silvery white with a slight smoky tinge. Abdomen white. Legs white sparsely dusted with fuscous scales and with last tarsal joint dark fuscous. Alar expanse, IS to 23 mm. Habitat: Orizaba, Mexico, August. R. Miiller, collector. Type: No. 14527, U. S. National Museum. Cotype in British Museum. Tortrix urbana, new species. Labial palpi reddish brown with darker tips. Face, head, and thorax reddish brown; antennae light brown, faintly annulated with black. Fore wings light reddish brown with numerous scattered black scales tending to arrange themselves as a transverse striation. A large oblique dark- brown transverse fascia from about the middle of costa to tornus is nar- rowest at the costal end and gradually broadens with bulging edges towards the dorsal side. Across the tip of the wing from apical fourth of costa to the middle of termen is another dark brown fascia, which is broadest on the costal edge. Hind wings light ochreous white. Abdomen ochreous fuscous. Legs ochreous; anterior tarsi heavily annulated with black. Alar expanse, 16' to 19 mm. Habitat: Mexico City. R. Miiller, collector. Type: No. 14526, U. S. National Museum. Cotype in British Museum. A common-looking species of the triferana Walker group, differing from this species in the more reddish ground color and the lack of light ochreous patches. Atteva exquisita, new species. Labial palpi white with a bluish-black annulation at the end of second joint and with bluish-black tip of terminal joint. Antennae black. Face white with a black transverse line. Head also white, with a black transverse line. Collar white with black anterior edge. Thorax reddish golden- yellow with white posterior tip and four black lateral dots. Fore wings with the rich reddish golden yellow ground color apparent only in the transverse fascia between the large silvery white spots, which occupy the greater part of the wing surface; extreme base of the wing red; then follows a large transverse silvery white fascia edged with dark metallic blue and with a serpentine metallic blue transverse line through the middle; next comes a reddish-yellow fascia at basal third, which is followed by another large silvery white transverse fascia, like the foregoing, edged with metallic blue and with a blue central line; following this is again a reddish-golden fascia, somewhat bent in the middle, and this is followed by a large dorsal silvery-white spot and by an adjoining small costal OF WASHINGTON, VOLUME XIV, 1912. 87 white spot, both with a crooked blue line in the center and both edged with dark metallic blue. On the apical part of the wing -'ire two costal white spots and one white fascia, separated and surrounded by metallic blue lines. Extreme apical tip golden yellow. Hind wings semitrans- parent, light fuscous with dark veins. Abdomen black with a conspicuous yellowish-white spot on the underside of each segment. Legs black, with narrow yellowish-white annulation at the joints. Alar expanse, 21 mm. Habitat: Mobano, Coahuila, Mexico, August. R. Miiller, collector. Type; No. 14528, U. S. National Museum. This species belongs to the anrea group, but differs consider- ably from any described species in the pattern of the fore wing as well as in the white color of the spots. One of (lie specimens, it should however be noted, has a straw-bellow tint over the outer white spots. —Mr. A. G. Hammar presented a paper on certain habits of the codling moth larva, relating to the reconstruction of the winter cocoon in the spring, the number of molts of the larvse, cannibalism among larva?, temperature control, an un- usual occurrence of two larvae passing the second winter in hibernation, and the ability of some larvae to subsist upon foliage. A brief account was also given on some of the main results of the codling moth investigation in Michigan, and the practical application of these findings. The full account of this investigation will be published as Bulletin 115 of the Bureau of Entomology, U. S. Department of Agriculture. At the conclusion of Mr. Harnmar's paper Mr. Rohwer asked if, in breeding the moths, the larvae of the sawfly which lives in apple had been noticed. Mr. Hammar stated that he had not observed them. Mr. Rohwer said that larvae are rather common in Europe and larvae with similar habits have been found in Washington State. In the same genus there are also larva1 which live in plums and cherries. In Mr. Hammar's paper were several allusions to tempera- ture control on the codling moth. These allusions led Mr. Pierce to remark on the fact that although temperature has a definite effect upon development, it will be found that for any degree of temperature the development will vary with the humidity, this variation sometimes being of considerable degree. 88 PROCEEDINGS ENTOMOLOGICAL SOCIETY Commenting on the effect of humidity on the emergence from the soil of adults of grape root-worm and plum curculio Mr. Johnson stated that his observations in rearing plum curculio in 1906 showed that emergence of beetles was re- tarded and in some cases prevented by withholding moisture, whereas in adjacent cages where moisture was supplied a maximum number of beetles emerged several days earlier. In the case of the emergence of adults of the grape root-worm it was observed in 1907 that a period of dry weather occurred during the first two weeks in July, which is about the normal time of the emergence in maximum numbers of the beetles in vineyards. Up to July 14 but very few beetles emerged, though in digging they could be found in their cells in the dry soil. Heavy rains fell on the 14th and during the following two or three days the adults emerged in large numbers. This emergence in the field corresponds with the cage experiments in which moisture was applied and withheld. Mr. Woglum mentioned the effect of hot dry weather on retardation in the emergence of adults of Aleyrodes citri in India. Practically matured pupse remained dormant during a continued hot dry period of ten weeks (July-August, 1911, temperature 85° to 120° F.) but emerged within a week fol- lowing first rain. -Under the title " An Old Question," Mr. Rohwer discussed briefly, the matter of local lists. The following is his abstract : Local lists may be divided into two classes : (a) geographical lists, or lists treating material collected within a certain definite geographical or political boundary; (/>) biological lists, or lists treating material collected within a definite faunistic area. For the purpose of studying geographical distributions biological lists are more useful. With the exception of Coleoptera, Neuroptera, and spiders very little has been done in the way of forming a local list of the insects of the District of Columbia and environs. The following papers are the only ones known which deal wholly with material collected in the above-mentioned locality. From time to time various new species have been described or recorded from this area, but none of these papers deal with this area alone. OF WASHINGTON, VOLUME XIV, 1912. 89 A list of the beetles of the District of Columbia. Ulke, 1902. Proc.U.S. Nat, Mus., vol. 25, No. 1275.

Wash., vol. 5, p. 154. Notes on some interesting flies from the vicinity of Washington, D. C. Townsend. Proc. Ent. Soc. Wash., vol. I, p. 224. To bring the matter before the Society it was suggested that: (1) An advisory committee of three be appointed; (2) a card system should be installed so that records could be made permanent; (3) a definite boundary for the limits of the local list be established. The advisory committee would be necessary as a directing force and to establish uniformity. A 5 by 3 card, ruled so as to have a space for the determiner, locality, date, collector, number of specimens, and disposition of the same, was suggested. Maps were passed around with various radii from the Capitol building drawn so as to give an idea of the area covered by any radius. The 20-mile radius would bring in all the favorite collecting grounds and give plenty of un worked territory. It was suggested that tin- division of the chosen area into certain smaller faunistic areas would be useful. Thus the swampy area along the Eastern Branch (Anacostia River) might be called S4. Part of the introduction in a "Guide to the Flora of Wash- ington and Vicinity" (1881) was quoted. The quoted part was that dealing with the comparison of the plants listed in "Florse Columbianae Prodromus" (1830), where it is stated that 81 of the plants of the (1830) work, "represent bona fide discoveries of species which either do not occur or are so rare as to have escaped the investigations of the present generation of botanists." It was also stated that to the knowledge of Mr. Heidemann certain species of Hemiptcra have become extinct in our local area. Mr. Pierce remarked that while local faunal lists are of considerable interest from a purely technical standpoint they have a high economic value. In the study of the cotton boll weevil the entomological complex includes all insects acting 90 PROCEEDINGS ENTOMOLOGICAL SOCIETY as hosts of boll-weevil parasites and then is complicated by the attacks of other insests on these hosts. The presence of certain weeds near cotton fields indicates the presence of typical weevils, with the probability of the usually associated parasites. The abundance of one species of insect frequently involves the reduction of another by direct or indirect means. It is imperative for economic workers to know their local fauna, because the species under investigation are certain to be affected by many other local species. Mr. Schwarz commented on the importance of publishing, or at any rate of collecting, local lists of insects. Among the multitude of local lists that have been published in North America, many of them are of little interest for the reason that they include only species of wide geographical range. Referring to Mr. Rohwer's plan of working out a faunal list of the District of Columbia insects, Mr. Schwarz said that he was greatly in favor of it, and that if the Society should not take any action he would heartily join the individual efforts of those members who take interest in the subject. Practically all active members of the Society are in the employ of the Government and are living within the city; they are laboring therefore under the difficulty that they can do field work only on Sundays or holidays. Mr. Schwarz alluded to the work done by the "Washington Biologists Field Club," which at its home on Plummers Island, in the Potomac River (about 10 miles fr.om Washington), has done considerable work toward preparing a local list of insects of the District of Columbia. -Under the heading "Notes and Exhibition of Specimens," Mr. R. A. Cushman spoke on a peculiar habit of the larvae of two parasitic Hynenoptera. He said : On May 5, 1911, I found two hibernating larvae of the codling moth (Carpocapsa pomonelld) under the bark of an apple tree. In removing them from the bark both cocoons were broken and the larvie were placed in a glass vial. When 'observed two days later both had spun cocoons against the glass, but without dimming the glass. This made it possible to observe the larvae clearly. One of the larva \vas much smaller than the other and of a pasty white coKSV, lacking OF WASHINGTON, VOLUME XIV, 1912. 91 the pinkish tinge of the healthy larvae. On May 11 a small parasitic larva appeared on the surface of this individual, having evidently emerged from its host just previously. This was at about 8 o'clock in the morning. Chancing to observe the parasite a few hours later I was amazed to find that it had in that short period at least doubled in size. By 5 o'clock the parasite larva had at least trebled in size since first ob- served in the morning and the host had been reduced to a pellet of skin pushed to one end of the cocoon. This rapid enlargement seems to be more in the nature of engorgement than of development. The parasite larva had begun its cocoon on May 12, at 8 a. m., about 24 hours after emerging as ;i small larva from its host, the adult appearing on the 24th. It was determined by Mr. Viereck as Ascogaster carpocapsa Yier., a braconid of the subfamily Cheloninae. A similar habit was a little later observed in the larvae of a chalcid of the genus Crototcchns. On May 18 Dr. C. \\'. Hooper handed me a living, but sluggish, full-grown cater- pillar of I\rophila pyramidoidcs. This I kept in a vial on my desk for observation. On May 23 the larva? of the para- sites appeared, emerging through the skin of the host, mostly along the sides. At first the parasitic larvae appeared like very small, shiny, green papillae or drops, as though the host larva had been repeatedly pricked with a fine point and the juices were oozing out. This illusion was maintained if not intensified as the parasites emerged slowly, and appeared to flow down the sides of the host. From the caterpillar in question about 90 parasitic larvae emerged. They were, how- ever, very small, and the host remained in much the same condition as a sphinx larva which is covered with the cocoons of . \p(intt-l('t somewhat shrunken but still retaining its form. But by the next morning, perhaps IS hours later, the chalcid larva1 had increased several times in si/e and the caterpillar was a mere shriveled skin, only the head shield retaining its original form. M will be noted that although the two species in which this peculiar habit of engorgement was observed are widely separated systematically, biologically I hey are alike in at least one respect both are internal parasites which leave the body of their hosts for pupation. In this feature of their life may lie the explanation of the habit of engorging on the fluids of their hosts, the possible reason being the greater ease of escape from the host for the smaller larvae. Dr. Howard expressed great interest in Mr. Cushman's observations. He had often seen the characteristic groups 92 PROCEEDINGS ENTOMOLOGICAL SOCIETY of pupae of Cratotechus upon leaves, but had never seen any remains of the host insect. Mr. Cushman's account of the rapid external feeding of the nearly mature Cratotechus larvae and the sudden diminishing of the host larva to almost nothing indicates that the remaining skin must easily be blown away, leaving nothing but the pupae of the parasite. —Mr. Quaintance spoke on the apparent effect of climate in restricting the western distribution of the plum curculio. An inquiry into the western limits of distribution of this insect has shown that it does not occur, except with one or two ex- ceptions, west of about the one hundreth meridian. In other words, it is confined to the humid area of North America. It is not understood why the curculio does not occur in some of the irrigated fruit-growing regions in the West, except that it perhaps has not been there introduced. This insect, during its transformation in the ground, is very susceptible to mois- ture conditions. As several observers have noted, the effect of the drought is to arrest the issuance of the beetle from the ground, whereas after a soaking rain these appear often in enormous numbers. Mr. Quaintance further remarked that it would be of much interest to follow up the effect of the very cold weather of the present winter on insect life in the environs of the District of Columbia. Collectors of insects in this territory have noted a more or less imtermingling of northern and southern forms, the proportion varying, depending upon the character of the winters during the preceding two or three seasons. Some in- teresting comments on this point were published by Dr. Chittenden in one of the Bureau of Entomology bulletins, issued some years ago. -Dr. Dyar exhibited two papers entitled "Contributions to the Natural History of Lepidoptera of North America, vol. 1, Nos. 1 and 2, by William Barnes, M.D., and J. H. McDun- nough, Ph.D. The first paper treats of the Cossidae of North America, the second of the lasiocampid genera Gloreria and its allies. Photographic figures are given of the species treated. Dr. Dyar said that the title was somewhat misleading, as there is no "natural history" as usually understood in tfee books, the taxonomy only being considered. However, Dr. Dyar OF WASHINGTON, VOLUME XIV, 1912. 93 thought that on the whole the publication was to be commended and that the original generic work and tables would prove very useful. The studies appeared to be based on sound lines, undesirable characters in the separation of genera being carefully avoided. The work is privately printed, presumably in small edition, so that it may be liable later to become scarce and difficult of access. -Mr. Schwarz called attention to a new entomological per- iodical "Entomologische Mitteilungen," just issued, the organ of the Deutsche Entomologische Museum. The first number- gives an interesting account of the difficulties with which the new institution had to contend before its permanent organization was accomplished. Besides the usual number of entomological articles it gives a photographic reproduction of the Deutsche Entomological Museum, which, by the way, is the only public, exclusively entomological museum hitherto built. This museum was founded by the late Prof. Dr. Kraatz and is the property of the municipality of Berlin, Germany, but under independent administration. The lead- ing spirit of this museum is Dr. Walther Horn, the lifelong friend of Dr. Kraatz. He is the well-known authority on the family Cicindelidse and his visit to Washington will be pleas- antly remembered by many of our Society. —Mr. Pierce stated that he had been interested for about eight 3'ears in the subject of insect dispersion. The boll weevil is controlled by the intensity of cotton cultivation. In heavy producing regions the weevils move 5 to 10 miles in a year, but where cotton is less extensively cultivated the movement may be as high as 120 miles. The extensive de- foliation of cotton in 1911 by the cotton-leaf caterpillar Alabama argillacca brought about a condition in heavy producing areas similar to the normal condition in sparsely cultivated country. As the consequence the weevil moved in the Delta region 50 to 60 miles. Swamp and lake regions may cause the weevils to fly 50 miles before finding cotton. In 1904 the Red River Valley limited the dispersion because of the heavy growth of cotton, which satisfied the weevils. Mr. Pierce also spoke of barriers to dispersion. Dryne.ss and altitude have proved effective barriers to the boll weevil. 94 PROCEEDINGS ENTOMOLOGICAL SOCIETY No weevils have been found in the Carolinian Life Zone, although cotton is grown in this zone. Minimum winter tem- peratures of 12° F. seem to be an effective barrier. If weevils have gone into hibernation they are not affected by tem- patures that would kill them if in the open. The minimum fatal temperature varies according to humidity. Dr. Dyar, speaking of the effect of temperature, stated that it depended in many cases on a minimum rather than average temperature. In this connection he commented on the yel- low-fever mosquito and the amount of area it is capable of covering. MEETING OF MARCH 7, 1912. The 257th regular meeting of the Society was entertained by Mr. Schwarz in the Saengerbund Hall, 314 C street N.W., on the evening of March 7, 1912, arid there were present Messrs. Babcock, Baker, Barber, Caudell, Dyar, Ely, Foster, Gahan, Heidemann, Hyslop, Johnson, Knab, McAtee, Mar- latt, Meyers, Pierce, Popenoe, Quaintance, Rohwer, Sandorf, Sasscer, Symons, Vickery, and Viereck, members, and Messrs. N. E. Mclndoo, J. R. Malloch, E. Marshall, W. Middleton, W. H. Sill, J. F. Strauss, R, S. Woglum, and W. B. Wood, visitors. President Quaintance occupied the chair. The minutes of the preceding meeting were read and ap- proved. Mr. Rohwer read a letter from the Danish "Naturhistoriske Forening," expressing a deep appreciation of the action of the Entomological Society of Washington in sending its Pro- ceedings to their society, and stated that said papers would be filed in the library of the University of Copenhagen. In return, they will forward to this Society copies of their pro- ceedings. Mr. Rohwer also read a letter written at the in- stance of the Executive Committee to Mr. George K. Burgess, of the Journal of the Washington Academy of Sciences, which reads as follows : OF WASHINGTON. VOLUME XIV, 1912. 95 MARCH 10, 1912. MR. GEORGE K. BURGESS, Bureau of Standards, Washington, D. C. DEAR SIR: Jn replying to yours of the first ultimo addressed to Prof. Quaintance, the Executive Committee of the Entomological Society of Washington request me to inform you as follows: The Entomological Society of Washington publishes a journal known as the Proceedings of the Entomological Society of Washington, in which the minutes and papers are published. In view of the fact that the Society has such ready pub- lication for its minutes, it is not deemed advisable or necessary to submit a copy of the minutes to you for publication. A copy of our Proceedings will be mailed to you, so that you can see our minutes as published. The matter of special papers has been brought to the attention of the members and they will act as they individually see fit. A canvass of the Society does not bring anywheres near enough copies of your Journal to secure the offer made the societies, by subscribing to twenty-five copies. Very truly, S. A. ROHWER, Corresponding Secretary. Mr. Caudell moved that the letter be sent. Seconded by Mr. Knab. Carried. Mr. E. B. Blakesley and Mr. H. E. Smith were elected active members and Mr. P. H. Timberlake corresponding member of the Society. Professor Quaintance proposed the name of W. B. Wood for active membership and in accordance with the rules it was laid over until the next meeting. The first paper of the evening, "New American Mites," by Nathan Banks, was read by title. The second paper, "Diptera at Home on Spider-webs," by Frederick Knab, was read by Mr. Rohwer.1 The last paper was "Notes on a Trip to India," by R. S. Wo glum.1 xNot presented for publication. 96 PROCEEDINGS ENTOMOLOGICAL SOCIETY NEW AMERICAN MITES. BY NATHAN BANKS. (Plates I and II.) The following new species are mostly of some economic value, and will be referred to in economic literature, so I herewith present their description. Tarsotomus erraticus, new species. Red.

Malloch, who re- sponded with a few general remarks on systematic entomology in Scotland. Commenting on the insects of this country, he stated that he found an unusually large number showing- light colors and bright hues as compared with those of Europe. -Under "Notes and Exhibition of Specimens," Mr. Marlatt commented on the present status of the quarantine bill and stated that it had now reached a satisfactory stage and would in all probability be made a law during the present session of Congress. He also referred to the action of the governor of California in calling a special session of the legislature for the direct purpose of placing a quarantine on Hawaiian fruits. The purpose of this legislation is to prevent the introduction of the fruit fly, which is now established in Hawaii. -Mr. J. A. Hyslop gave the folio wing notes from the Pacific Northwest. He said : The food of Laropsis, sp. n., Rowher : While driving through a fallow field at Govan, Washington, on August 24, 1911, I noticed one of these wasps awkwardly traveling over the ground, half flying and half walking. On closer examination it was found to be carrying a locustid with which it was un- able to fly. The insects were collected and when submitted, respectively, to Messrs. Rohwer and Caudell, of this Society, for determination, both proved to be new species. The locustM was a species of Phrixocncmis as yet undescribed. Brachycistis ampins Blake : These mutillids have occured in great numbers each spring of the three years that I have spent in the semiarid Big Bend country of Washington, viz, 1909, 1910, and 1911. At Conell, on April 5, 1910, they were so numerous about lights as to remind one very forcibly of the annual flights of ephemerids in this city. At Govan they were decidedly troublesome, flying into and clogging the lamp chimneys. Crioccphalns product us Lee. : These cerambycids have been extremely numerous during the month of August of the past three years at Pullman, Washington, where they were very troublesome, entering houses and flying about lights in a head- long manner, as do lachnosternas in the east. As many as ten were collected in my room in one evening. These beetles are known to spend their larval stages in Pinns poiiderosa and are probably brought to Pullman as larvae and pupae in cord wood, as the nearest standing timber is 12 miles away. OF WASHINGTON, VOLUME XIV, 1912. 101 Olethreutes rubipunctana Kearfoot : The larvae of this moth were quite numerous in the dry seed-pods of the common iris (Iris missotiriensis) about Pullman. The larvae feed on the seed and spin a cocoon within the seed chamber, wherein they hibernate during the winter. Larvae were collected on March 12, 1910, from which three specimens of the parasite Ascogaster sp. n. emerged on May 11 and one more parasite on June 20. In 1911 iris seed-pods containing these lepidop- terous larvae were again collected and on June 15 an adult moth emerged. Crambns cypridalis Hulst : A remarkable flight of these moths occured at Pullman for three nights, September 23, 24, and 25, in 1911. The moths were so numerous about arc lights that they gave the light the appearance of being enveloped in a driving snow storm. Aphochantus desertus, Coq. : The pupa of this fly was found in the pine-needle mold that had accumulated in a hollow on one of the large bowlders which cap the summit of Moscow Mountain, Idaho. The pupa was collected on July 24, 1910, and placed in some of the extremely dry mold in which it was found, in a box. On August 24 the fly emerged. Tephritis jinalis; The larvae and puparia of these flies were found in the floral heads of the wild sunflowers (Bal- samorhiza sagittafolid) at Pullman on May 9, 1910. They always occurred one in a seed capsule and averaged over 6 flies to the floral head, 70 flies having been reared from 11 heads. The flies started to emerge on May 24 and continued emerging until June 2. However, these floral heads were moistened and probably presented abnormal conditions that disturbed the normal appearance of the adults. —Mr. Pierce stated that he was preparing a treatise on the biologies of North American weevils, including notes also on Central and South American forms. There are important gaps in our present knowledge of these insects and compara- tively little is known of the breeding habits of our Otiorhyn- chidae and Rhynchitidae. Any help along these lines which will enable him to work out some of these difficult problems will be appreciated, and/if possible, he prefers to use published records, so that the credit may go to the original observer. Mr. Pierce also summarized the classification of the tem- peratures as used in the study of the boll weevil. The various temperatures are grouped into zones in accordance with their effects on the insects, as follows : 102 PROCEEDINGS ENTOMOLOGICAL SOCIETY 0 Fahr. Lower zone of fatal temperature — 5 to 22 Zone of hibernation 22 to 56 Zone of activity . 56 to 91 Zone of aestivation . 91 to 122 Upper zone of fatal temperature 122 to 140 -Mr. McAtee, commenting on the hibernating insects on Plummers Island, Maryland, stated that numerous specimens of Bembidium and Corythuca, taken under bark, were brought into the laboratory, but that none had shown signs of life. The following captures were recorded : 60 Milyas cinctus were found together under bark of tulip tree and 19 Pyrellia cyanicolor, including both sexes, were taken from an ant gallery in an old fallen log. The close packing of the flies and the fact that some had crowded into small parts of the gallery were of interest, as the behavior is in such marked contrast to their love of freedom during summer months. -Mr. Quaintance commented on the economic importance of a knowledge of temperatures fatal to insects. Important use is being made at the present time in the control of insects in mills by heating the same to a temperature destructive to the common mill species. A most excellent piece of work on this subject is now under way by the Kansas Agricultural Experiment Station, under the immediate direction of Mr. Dean. Sufficient information is at hand to indicate clearly that insects infesting plants may often be destroyed by the use of water heated to a temperature fatal to the insects and not injurious to the plants. For instance, the employment of hot water in dipping nursery stock, grafts, and scions to de- stroy the common woolly apple-aphis, Schizoneiini /au/^eni. The use of hot water in this way dates back many years as well as against the common peach borer, Sanninoidea cxitiosa. There is need of an extended investigation of the subject, as it appears to offer important possibilities in insect control. -Mr. A. B. Gahan gave an account of a chironornid fly breeding in well water. He said : Last fall the writer was requested to investigate a com- plaint by a resident of College Park, Maryland, that his well water was being rendered unfit for use by the presence in it of numerous small red "worms." Accordingly, an investi- OF WASHINGTON. VOLUME XIV, 1912. 103 gation was made, October 4, 1911. The well in question was found to be an ordinary dug well covered with a loose plank platform and containing a pump. It was about 25 feet in depth, partly bricked up and partly woodcased, and situated on a side hill, where it undoubtedly received some surface water, as was evident from the presence in the bottom of the well of a considerable quantity of very fine clay silt such as constituted the surface soil in the vicinity. The water, which was 4 or 5 feet in depth, was reasonably clear at this time, but possessed a ver}r faint odor. The householder stated that for several weeks he had been compelled to strain the water through a cheese cloth in order to rid it of these worms. Examination of the cloth tied over the mouth of the pump at the time of my visit showed it to contain a dozen or more that had been pumped up during the previous half day. These were readily identified as the larvae of a chironomid fly. A second visit to the well on November 15 showed the larvsc still present in about the same numbers, and upon lifting a board from the plank platform a number of small midges were seen to escape. A careful scrutiny of the under- side of the remaining boards resulted in the discovery of numerous specimens, eight of which were captured. On November 23 several additional adults were taken and by means of a dredge net over 50 of the larva? were secured. Al- though special effort was made to secure eggs and p'upse, none were obtained, owing probably to the lateness of the season. The captured larva-, which were all apparently nearly full grown, were taken to the laboratory and placed in two sepa- rate beakers of the well water, about equal numbers of larva- in each. One beaker contained only the clear water, while in the other a small amount of the fine clay silt from the bottom of the well was placed. When placed in the water they im- mediately began the peculiar and apparently useless opera- tion, characteristic of chironomid larvre, of jerking the body alternately from side to side, the tail touching the head first on one side and then on the other. So far as could be observed this movement served no useful purpose, since the insects made no progress forwards or backwards by it. On the con- trary, they sank straight to the bottom of the beaker. Here their wiggling was of more avail, as in contact with tin glass they were able to move awkwardly about. Somewhat to my surprise, it was soon evident that those in the beaker containing the clay were not prospering. Their constant wriggling tended to draw them down into the mud, from which they were unable to extricate themselves. At 104 PROCEEDINGS ENTOMOLOGICAL SOCIETY first it was thought that the larvae were attempting to conceal themselves, but it soon became evident that this was not the case. The following morning all except three or four of those , in this beaker were found to be dead, having apparently succumbed to suffocation. On the other hand, those placed in the beaker of clear water soon collected a mass of fine debris which they fastened to- gether by means of fine threads, thus constructing a shapeless case within which all concealed themselves. Here they re- mained alive for several weeks, never voluntarily leaving their hiding place, at least during daylight. Only two of these larvae were induced to pupate. The first pupa was observed the morning following collection. It was lying flat on the bottom of the beaker and so remained until the emergence of the adult four days later. When disturbed it would dis- play some feeble movement, but at no time was it active. The second pupa was formed within the above-mentioned case. In neither case was the act of emergence observed. " The principal feature of interest in connection with this species is the unusual habitat. Species of Chironomus are known to breed in lakes, sometimes at great depths, in stag- nant pools and ponds, and even in running water, but this is the first instance known to the writer of a species being known to breed in a closed well. The larva is of the type possessing two pairs of blood gills, is blood-red in color, due according to Miall to the presence of hemoglobin, and is thus adapted to living in deep water instead of at the surface. That the larvae in question do in fact live at the bottom of the well is shown by their behavior in the beakers, where they were under almost constant observation for over two months, and were never seen to rise near the surface. This habit of deep living accounts for their being brought up by the pump, the screen of which is near the bottom of the well. Specimens of the adults were sent to Prof. 0. A. Johannsen, Orono, Maine, who has kindly identified them as Chironomus dorsalis Meig. It is not probable that the presence of these insects in the water has any considerable deleterious effect in itself. Rather is it believed that their presence is an indication of contamina- tion from other sources. Their presence, however, is in no way desirable in water intended for household purposes, and should the habit of breeding in wells become general, it will present a problem of some economic interest. Dr. Dyar said that the presence of the larvae in the well was probably induced by the wooden walls, which would furnish OF WASHINGTON, VOLUME XIV, 1912. 105 food. He thought no larvae would be found in the wells en- tirely lined with stone, as is ordinarily the case. Mr. Knab stated that the idea that the red color of chi ronomid larvae indicated that they inhabit deep water is er- roneous. He had on several occasions found large colonies of such blood-red chironomid larvae in very shallow water and evidently thriving.

In cataloguing the Rhynchophora of the United States National Museum in a paper entitled "Studies of North American Weevils," the author, Mr. W. Dwight Pierce,1 mentions a species of otiorhynchid weevil, under the genus Phacepholis, designating it as "Ph. vin'dts stating that it is the most brilliant green form of the genus, mentioning the type locality (San Antonio, Tex- as), and date of collection (May 21, 1900), with the ad- ded statement that it was found on fruit trees, and placing it as a synonym of Phacepholis e/cgans Horn. In a supplement to their article on the Rhynchopho- ra of Central America, Dr. D. G. Sharp and Mr. G. C. Champion,2 again using the writer's name as authority for this species, mention structural characters — the much more prominent eyes and the very convex acuminate-ovate elytra, and figure the species, too lightly colored. The danger of using manuscript names and the confusion that results as a consequence is well exemplified in the present species. It leaves a question as to who first described the species — Mr. Pierce, who attempted to sink the writer's MSS. name as a synonym, or Sharp and Champion, who point out two structural characters, and figure the female, which ;ils<> indicates characters. Since the published statement has been made that the writer will shortly publish a description, the following is submitted. The species is removed to the genus Pantomorus Schcenh.

Female. — Robust pyriform with elytra strongly convex; elytra and thorax densely coated with brilliant metallic green scales, the thorax more sparsely covered and with the scales mostly larger and with a bluish cast. Head broad, eyes nearly round and prominent. Thorax nearly as long as wide, sides strongly arcuate. Head, lower surface and legs coated with pale pinkish scales. First joint of funicle of antenna about half as long as second, second longer than next three together. Male. — Body much narrower. First funicular joint about one-third as long as second. Length, 5.5 to H.5 mm.; width, 2.5 (male) to 3.4 mm. Habitat: San Antonio, Texas (type locality), where it was reported injurious to peach, plum, and pear, May 21, 1900; Guanajuato and "Sierra de Durango," Mexico (Champion). Type: No. 9756, U. S. National Museum. The wider head, rounded, prominent eyes and antennal structure distinguish this species from elegans. A fairly large series of each shows such variability that other constant structural characters cannot be readily seen. The colors are very nearly constant in the present species and the basal margin of the thorax (which varies in length) is usually dis- tinctly reflexed. It is larger than elegans and the female is much more robust than our other species. In elegans the second joint of the funicle is usually shorter than the next three together. Finally, it should be added that it is not nearly related to elegans, but is similarly colored. RECORD OF THE FINDING OF A TRUE QUEEN OF TERMES FLAVIPES KOL. BY THOMAS E. SNYDER, Bureau of Entotnologv, U. S. Department of Agriculture. (Plate ill.) While investigating damage by wood-boring insects to the bases of telegraph and telephone poles, a true fertilized queen of the species Tcrnics flaripes Kol. was found in the butt of a chestnut telegraph pole on August 12, 1910. The pole was standing on the right of way of the Seaboard Air Line R. R. about 3* miles southwest of Portsmouth, Virginia. The soil was sandy and dry near the surface. The true queen (pi. in, a) when found was inactive in a gallery no wider than her abdomen, probably a burrow of 108 PROCEEDINGS ENTOMOLOGICAL SOCIETY Lymexylon sericeum Harr., in the outer layers of the wood, below the surface of the ground. Injury by termites to this pole was confined to the outer layers of the wood, where there was incipient decay. Apparently she was unattended. On being exposed to the sunlight her abdomen appeared to have a greenish tinge. This queen is approximately 14 mm. in length. The queen had been fertilized, as is shown by the distended abdomen. Wing stubs were present. On the same day a supplementary queen (pi. in, b) was found in the butt of another chestnut telegraph pole nearby. Termites had mined the heartwood to a depth of from 2 to 4 inches in from the exterior in this pole. This queen was active and was associated with workers; all were moving apparently to escape the light as the mines were laid open by the axe. She was in the outer layers of the wood, where there was in- cipient decay. This queen is approximately 12 mm. long. The head, thorax and scutellar area of the abdominal segments of the true queen are more heavily chitinized and deeply pigmented. The supplementary queens never have developed wings and lack the deeper pigmentation (pi. in, a) of the chitinized parts and the ocelli are not so prominent as in the true queen — indications that the supplementary queens never leave the colony. A small scarabseid ( Valgits canaliculatus Fab.) was found very abundant in termite colonies in decaying oak stumps near Rock Creek Park, Maryland. NOTE. — A study is being made of the more common Americantermites of the genus Termes with a view of determining methods of preventing injury by them to various classes of forest products. Any additional records of the conditions under which queens have been found in the past will be of value. It is believed that this is the first fertilized true queen ever found of this species. — T.

XIV JULY - SEPTEMBER, 1912. No. 3 SPECIAL MEETING OF MARCH 14, 1912. A special meeting of the Society was held in Room 2, Bu- reau of Entomology, U. S. Department of Agriculture, to take action on the death of Dr. John B. Smith. President Quaintance occupied the chair, and there were present Messrs. Barber, Blakesley, Currie, Heidemann, Hop- kins, Howard, Hyslop, Johnson, Middleton, Phillips, Popenoe, Quaintance, Rohwer, Russell, Sasscer, Seigler, Simaton, Wal- ton, Webster, Wood, and Zimmer. President Quanitance appointed a committee of three, con- sisting of Messrs. Howard, Hopkins, and Webster, to draft suitable resolutions, which were to be sent to the family of the deceased and printed in the Proceedings of the Society. The committee reported the following resolutions : Whereas, the Entomological Society of Washington has learn- ed with the deepest regret of the death of its former active member and most highly esteemed corresponding member, Dr. John Bernha'rd Smith; And whereas, Doctor Smith had been closely connected, both personally and by correspondence with Washington ento- mology for a quarter of a century; And whereas, by his admirable work and strong personality he had long since gained the respect and esteem of the members of the Society : Therefore, be it Resolved, That in the death of our former member the Society has lost one of its valuable assets; American entomo- logy has lost one of its foremost workers; the State of New 111 112 PROCEEDINGS ENTOMOLOGICAL SOCIETY Jersey has lost an earnest, indefatigable, far-sighted, and most competent official; Resolved further, That the Entomological Society of Washington extends to the widow and the family of its late member its warmest sympathy, and at the same time its ap- preciation of the fact that the distinguished career of the late husband and father must always be a source of satisfaction to those left behind. L. O. HOWARD,. F. M. WEBSTER, A. D. HOPKINS, Committee on Resolutions. Doctor Howard made the following remarks : Another of the founders of the Entomological Society of Washington, Dr. John Bernhard Smith, has died, passing away yesterday morning at 3 o'clock after a Long illness. His end was probably due to chronic heart trouble complicated by Bright's disease. Our former colleague was born November 21, 1858, in New York City, and was educated in the schools of New York and Brooklyn. He was admitted to the bar in 1880 and practiced law In Brooklyn between 1880 and 1884. He became special agent of the then Division of Entomology, Department of Agriculture, in 1884, and for two years he did field work, especially upon insects affecting the hop and cranberry. In 1886, he was made aid in the Division of Insects, U. S. Nation- al Museum, holding this position for four years. In 1890, he was made entomologist of the agricultural experiment station of the State of New Jersey, and was made State Entomologist of New Jersey some years later. I have never learned, and I don't think he ever told me, just when he began to collect insects and to become interested in entomology. I imagine that Charles Fuchs and Frank Schaupp had something to do with it. At all events, they were all together in the early days of the Brooklyn Entomological Society. Doctor Smith became the second editor of the bulle- tin of that society, which he afterwards developed into Ento- mologica Americana, and of this later wrell-known journal Dr. Smith was editor from 1886 to 1890, when he was suc- ceeded by Dr. F. H. Chittenden. His interests from the start were in the Lepidoptera, and this interest continued the rest of his life, and he became, as every one knows, one of the best known workers on the great complex known as the Family Noctuidse. OF WASHINGTON, VOLUME XIV, 1912. 113 His first introduction into economic entomology came in 1884, when Dr. Riley brought him to Washington, b\it his work in 1886-1890 was again purely systematic. During his six years in Washington he became a well known figure among the naturalists of the city, and was at one time secretary of this Society, and later, secretary of the Biological Society of Washington. When the agricultural experiment stations were founded, he was one of the first State workers appointed, and from the very start his energy and capacity made him one of the fore- most workers in this line of research. He was interested in and active in every new development of economic entomology and was a prominent figure at every meeting of the Associa- tion of Economic Entomologists, holding the office of secretary at the first and second annual meetings of the association, in 1889 and 1890; second vice-president in 1893; first vice-presi- dent in 1894; and president in 1895. He carried on his dual work as a systematic entomologist and as an intensely practical economic entomologist down to within a short time of his death. He was not only held in great respect among the entomologists of this country and of Europe, but he had the highest standing among the citizens of the State of New Jersey, of which he was an official. Further, he had the respect and confidence of the citizens of New Bruns- wick, in which city he lived, and of the faculty and student body of Rutgers College, with which he was connected and which had given him, in the early nineties, the honorary degree of doctor of science. While practically all of Doctor Smith's work was sound and deserving of every respect, it seems to me that the triumph of his life was in the results obtained by his anti-mosquito work. I can do no better than to quote from my address before the Seventh International Zoological Congress as follows : The mosquito destruction measures carried on by English workers, and especially by those Connected with the Liverpool School of Tropical Medi- gine, in different parts of the tropics controlled by England, have been large- ly scale work of great value. That done by the army of occupation in Cuba was of enormous value, so far as the city of Havana was concerned, and an assistant just returned from the Isthmian C'anal Zone assures me that it is possible to sit now out-of-doors of an evening upon an unprotected veranda anywhere in the Zone without being annoyed by mosquitoes, and without danger of contracting malaria or yellow fever. These are all great pieces of work, but when we consider the condition that exists in the State of New Jersey, and the indefatigable and successful work of Doctor Smtih in the handling of the most difficult problem of the 114 PROCEEDINGS ENTOMOLOGICAL SOCIETY species that breed in the salt marshes, and of his persistent and finally successful efforts to induce the State legislature of that wealthy but ex- tremely economical State to appropriate a large sum of money to relieve New Jersey from its characteristically traditional pest — we must hold up our hands in admiration. One important lesson learned from Doctor Smith's suc- cessful career is that it is possible for a man of adaptability, of force of character, and of keen perception, without univer- sity training and without any training in biological research, to take up both systematic and economic entomology after reaching manhood and to become in the course of a short life one of the prominent men of the Nation. It is a sad and curious coincidence that both Charles V. Riley and John B. Smith died at the same age. Doctor Howard made some additional remarks and quoted a letter from Dr. Smith, dated February 23, 1912, as follows: DEAR DOCTOR HOWARD: Yours of the 10th inst. is at hand. No, it is nothing serious. It only means the preliminary to a funeral, and that is one of the commonest things that occurs. Professor Webster made the following remarks : I think it must have been about 1885 that I first began cort responding with John B. Smith, and I remember well his firs- letter, and remarked at the time its hearty spirit of comrade- ship. While I did not meet him until a number of years after- wards, that same spirit was true of him all of his life. Dr. Smith never was too busy to help anybody. You might go to him when he was in the midst of his work and he would drop everything and try and help you; I have always noticed, too, that, in all of our entomological associations and societies, Doc- tor Smith was always ready to take hold and wTork, and worked like a Trojan. It has always been a wonder to me how one man could accomplish so much; how he found time to even try to do some of the things that he did. Of course in a man so prolific, it would be almost beyond human endurance for him to be always exact. Sometimes we would get out of patience with him over his mistakes and tenacity in holding to them, yet could not stay out of patience any length of time. Of course, the work that he did will be revised, and more or less, perhaps, dropped out, which is true of all of us; but after all error is sifted out, though cut off in his prime, there will be a good life's work left. I do not believe I can say anything more than that he will be sadly and universally missed, ex- OF WASHINGTON, VOLUME XIV, 1912. 115 cept to emphasize his universal good nature and his willing- ness to aid everybody in any way and he never seemed to be too busy to do so. Doctor Hopkins made the following remarks : To my personal knowledge I first had correspondence with Doctor Smith immediately after taking up work in the "Wol Virginia Experiment Station in 1890. Directly after Doctor Smith had been appointed to New Jersey, I had been studying some insects, especially those found on hackberry, mulberry, and raspberry. I had made some drawings that I thought were very good, but after seeing some drawings made by Doctor Smith, I sent them to him for his criticisms, and he was very severe in his criticism. He said they were not worth repro- duction and they were very poor, and his exceedingly frank expression attracted me, and I may say that it had some in- fluence, because I made up my mind then that I would make as good drawings as Doctor Smith. It was my pleasure some four or five years after that, at one of the annex meetings, I think at New York, of the association in 1894, at which Doc- tor Smith was exhibiting some of his drawings of the clerid that I introduced from Germany, and after he had exhibited his drawings, I passed mine around, and he complimented me es- pecially on the excellent work, and I called his attention to the fact that this was one time that he did not criticize my drawing, so that sometimes one does good by having his work criticized, and I think that his criticism did a greal deal towards my attitude to do some good drawing. This is, I think, one of the instances which might be worth mentioning. At our meetings of the American Association, Drs. Smith and Fletcher and a few others were always the remaining members of the annex meeting, and will always be remembered with great pleasure. Mr. H. S. Barber made the following remarks : I had the great pleasure of being out in the country one full day with Dr. Smith and Mr. Schwarz, and the \viiy they seemed to enjoy each other, after a long separation, was one of the .prettiest things I ever saw in my life. Both of them were just overjoyed all the time. It was one of the pleasant- est outings I ever had. Mr. Quaintance made the following remarks: I would merely say that I first met Doctor Smith, I think, at the Columbus meeting of the American Association, and 116 PROCEEDINGS ENTOMOLOGICAL SOCIETY indorse thoroughly what Professor Webster said as to his ex- tremely good nature, and I used to think a great deal of him, and the more I knew of him personally, the higher opinion I had of him as a man. I think I had correspondence with him first, perhaps, in 1893, in connection with the determination of some common noctuid moths from Florida. They were all very common and I should have known what they were, but I had just began the study of insects at that time and he let me down very easy. They represented the bollworm moth (Heliothis) and perhaps the cabbage worm and similar in- sects like that. I am sorry that I have not his letter to read to show you how nicely he treated me in regard to the matter, being a beginner in the subject. On another occasion, Doctor Hopkins' remarks about drawings remind me of an experience I had in that particular. I had made certain observations on a little weevil which infests seed corn, and not knowing how to make drawings, I made them very large. Dr. Smith at that time was editor of the section of entomology in Entomo- logical News devoted to economic entomology. I sent them on to him with the manuscript and he complimented me on the paper. He said "Why did you make your drawings so large? They are enormous." He offered to redraw them and-reduce them, which he did. Mr. Currie made the following remarks : I never was associated with Doctor Smith to any extent, but at the times when he visited Washington and the National Museum in former years I always enjoyed meeting him greatly and I admired him for his cordial personality and abounding enthusiasm. I always admired the records of the work that he left in the Division of Insects in the National Museum. In the old record book, in which the first accessions to the Divi- sion of Insects in the National Museum were made, we have the entries made in Doctor Smith's own handwriting. The amount of work that he evidently did was quite remarkable. While he was Assistant Curator of the Division of Insects he accomplished much work in arranging various groups and did considerable work on the exhibition series in various groups. I suppose that at that time he was about the only one employed at the National Museum to care for the insect collections. He was succeeded later by Mr. Martin L. Linell. Those were the days when one man had to take charge of a great variety of groups and the arrangement of them, and had many duties. Of course, his most notable systematic work was perhaps tint in connection with the collection of Noctuidae, and even after OF WASHINGTON, VOLUME XIV, 1912. 117 he left Washington specimens of his new species were con- stantly being added to the collection. He sent the new speci- mens or species themselves or, if that was not possible, he saw to it that photographs or drawings were put in place in the collection, so that the series would be as complete as it was possible to make it. After the resolutions were adopted, the meeting was ad- journed at 4.30 P. M. The following papers were accepted for publication : A NOTE ON THE SOUTHERN WALKING-STICK (ANISO- MORPHA BUPRESTOIDES STOLL) AND A TACHINID PARASITE. BY H. M. RUSSELL. Bureau of Entomology, U. S. Department of Agriculture. While at Cutler, Florida, May 8, 1908, the writer captured a pair of walking-sticks in copulation belonging to this species. They were placed in a tin box and left until May 12, when upon opening the box to kill the female it was found that 10 eggs were lying loosely upon the bottom. The female when grasped expelled a milky fluid possessing a very disagreeable odor in a very fine mist from some part of the abdomen, re- peating this as often as handled, although the quantity di- minished each time. The egg is 4 mm. long and 2 mm. in diameter, shaped exactly like a bean, both ends flattened and one side with a scar in the side similar to one on a bean where it is attached to a pod; anterior pole with round cap fitted so as to open when larva pushes on it; color gray, cap with blackish spot in center, scar on side black, surface with few raised wavy lines running lengthwise and between a number of very minute raised wavy lines. Five dipterous pupae were also found in the box, which must have come from the female, although the parasitism did not prevent her from laying the eggs. May 29, 1908, a male fly, a tachinid, emerged from one of these pupa1, and was described as Phasmophaga meridional^ by Mr. C. H. T. Townsend, in the Annals of the Entomol- ogical Society of America, vol. 11, p. 224, 1909. 118 PROCEEDINGS ENTOMOLOGICAL SOCIETY A CONTRIBUTION TO NORTH AMERICAN DIPTEROLOGY. BY HARRISON E. SMITH, U, S. Bureau of Entomology , Melrose Highlands, Mass. In the following paper are included the descriptions of several new species of North American Tachinidae and Syrphi- dse; also a summary of the North American representatives of the genus Hyperecteina Schiner. I am under obligations to Mr. Frederick Knab and Mr. C. W. Johnson, each of whom very kindly offered much valuable advice and criticism; also to Dr. L. O. Howard, who made possible my opportunity to examine many of the types for comparison. FAMILY SYRPHID^. Helophilus willingii, new species.

Described from one female specimen taken at Moscow, Idaho. Type: No. 14698, U. S. National Museum. HYPERECTEINA Schiiier. The writer having experienced considerable difficulty in satisfactorily determining several specimens of this genus by the aid of Coquillett's "Revision of the Tachinidse North of Mexico," and his later descriptions of members of this genus, recently had the good fortune to examine in the U. S. National Museum all of the representatives, including many of the types of this genus, described from America north of Mexico. As a result of this study it was possible to arrange what is hoped will serve as a satisfactory key to the described repre- sentatives of this genus in America north of Mexico. Bezzi and Stein, in their "Katalog derPalaarktischenDipter- en," recognize the genus Admotitia, described by Brauer and Ber- genstamm in 1889 with Degeeria arnica Meig. (aspodomyia, new species) as the type of the genus. They have placed Ilyperecteina Schiner in the synonymy. The genus Hyperec- teina was described by Schiner in 1861 ; as it is not preoccupied, just how they arrived at this conclusion is somewhat of a mystery, as they include in the genus Admontia the species metopina, the type species of Hyperecteina, so designated by Schiner himself. In other words, they have entirely overlooked the fact that Schiner described the genus Hyperecteina with OF WASHINGTON, VOLUME XIV, 1912. 123 metopina, a new species described by himself as the type some twenty-eight years before Brauer and Bergenstamm des- ignated Degeeria arnica Meigen as the type of their genus Admontia. Degeeria arnica Meigen, therefore, becomes merely Hyperecteina arnica Meigen. Mr. Coquillett has pointed out this fact in his paper, "The Type-species of the North American Genera of Diptera." The representatives of the genus in America north of Mexico may be separated as follows : 1. The third abdominal segment in the female at most only nor- mally carinate on the venter The third abdominal segment in the female abnormally carinate on the venter, the carina forming a wide lateral ridge and thickly beset with short black spines; front in the male two-thirds as wide as, in the female as wide as either eye; bristly hairs on the sides of the face not arranged in a single row; the third antennal joint in both sexes nearly twice as long as the second; arista thickened on the basal third, the penultimate joint broader than long; sides of face each nearly one-half as wide as the median depression ; cheeks one-fourth as broad as the eye-height; facial ridges bristly on the lowest one-fourth to two-thirds; abdomen gray pruinose on the basal margins of the last three seg- ments; bearing both discal and marginal macrochaetae; three sternopleural macrochaetse; the third vein bearing . two or three bristles at its base.

The writer presents these short notes at the present time as two of the species treated, Heliothrips rubrocinctusQisxdL and Eiithi ips insularis Franklin, have not been recorded from the United States, and the third, ^olothrips bicolor Hinds has heretofore only been recorded from Amherst, Massachusetts. Heliothrips rubrocinctus Giard. This species was observed by the writer to be seriously affecting the mango and avocado trees at Miami, Florida, during the months of January to May, 1909. It was found feeding in colonies on the foliage in all of its stages and ming- ling in with Heliothrips hcemorrhoidalis Bouche. In habits it was almost identical with the latter, but the younger stages were readily distinguished by a bright red band crossing the base of the abdomen, and the adult by its habit when dis- turbed of curling the abdomen entirely over the body and then moving away in that posture. Euthrips insularis Franklin. On January5, 1909, Messrs. H. 0. Marsh and D. K. Mc- Millan collected this thrips in large numbers at Brownsville, Texas, in the blossoms of the velvet bean (Dolichns atropur- pureus). Franklin described this species from the Barbados Islands, and Mr. David L. Crawford collected it at Guadala- jara, Mexico, where, he stated, it was the commonest thrips present. On the velvet bean, this insect was causing consider- able injury by feeding on the flowers. This was indicated by a brown spotting of the petals, many blossoms dropping off, so that there were few pods maturing. .^Eolothrips bicolor Hinds. While Mr. M. M. High was engaged in work on the onion thrips (Thrips tabaci Lind.), at Knox, Indiana, during August, 1911, he collected a number of specimens of this thrips. They were taken in company with sEolo thrips fasciatus Fab. on the onion, where they were observed to be feeding on the onion thrips. OF WASHINGTON, VOLUME XIV, 1912. 129 DESCRIPTIONS OF NEW NORTH AMERICAN THYSANOPTERA BY J. DOUGLAS HOOD, United States Biological Survey . The classification of the order Thysanoptera is admittedly much in need of attention, and reliable synopses of genera and species are conspicuously wanting. A proposed treatise for the Genera Insectorum, now in preparation by Richard S. Bagnall, will do much to supply these long-felt wants; and in advance of its publication it seems desirable to make known a maximum number of so-called species, for the value of such a work of reference depends largely upon its exhaustiveness. In this paper I have thus attempted nothing more profound than the mere description of certain forms and groups of forms which appear after a morphological study to require new names for their proper designation. SUBORDER TEREBRANTIA HALIDAY. FAMILY ^EOLOTHRIPID^ HALIDAY. yEolothrips vittipennis, new species. (PI. IV, figs. 1, 2.) Female. — Length about 1.5 mm. Color dark blackish brown with a reddish cast, due to dense crimson hypodermal pigmentation in the tho- rax, abdomen, femora, tibiae, and the two basal antennal segments; anten- nae with segnent 3 and basal half of segment 4 yellowish white. Head about as wide as long, longer than prothorax, deeply and closely transversely striate, and with numerous minute spines on occiput and cheeks ; anterior border deeply emarginate' by the forward production of the eyes, and wii'h a median tubercle; cheeks strongly arcuate. Eyes moderate, prolonged on ventral surface of head, and with the more dorsal facets separated by a distance about equal to their own diameter. Ocelli equi- distant, the posterior nearly contiguous to eyes. Antennee about 2.2 times as long as head, the last four segments subequal and together shorter than the preceding; sensory area on ventral surface of segment 5 elongate, the sense cone arising from basal end; segment 3 yellowish white, becoming darl- blackish brown at extreme apex; 4 yellowish white in basal half or thirl, excepting for the dark pedicel; remainder of antenna blackish brown. Madllary palpi three-segmented; labial palpi four-segmented. Frothorax subrcetangular, slightly shorter than head, and nearly one and one-half times as wide as long, widest near middle; surface with num- erous minute spines. Mesothorax about 1.5 times as broad as prothorax, arterior angles broadly rounded; mesoscutum very closely transversely striate. Metathorax with sides roundly converging posteriorly; meta- ffiutum subreticulate. Wings of fore pair slender, about 8.5 times as long is width at middle, of nearly equal breadth throughout; venation normal; inal Half occupied by a longitudinal black band which extends from the 130 PROCEEDINGS ENTOMOLOGICAL SOCIETY extreme base, across the scale, and to the tip of the wing, sometimes show- ing a tendency to form a transverse band just beyond the basal third;1 hind wings white or grayish. Legs normal to genus, the fore femora slender. Abdomen slender, normal to the genus. Male. — Length about 1.1 mm. Fore wings with a transverse black band just beyond the basal third, in addition to the longitudinal band on pos- terior half. Abdomen very slender; ninth segment nearly as long as wide, narrowed toward apex, and without clasping organs. Measurements of holotype: Length 1.48 mm.; head, length 0.180 mm., width 0.197 mm.; prothorax, length 0.148 mm., width 0.218 mm.; mesotho- rax, width 0.320 mm; abdomen, width 0.342 mm.

Described from 10 females and 8 males, taken on honey locust (Gleditsia triacanthos L.),at Topeka, Illinois, May 23, 1909, and August 7, 1908, by Mr. Charles A?Mart,and one living female from Washington, D. C., July 28, 1912, J. D. H., on yellow locust (Robinia pscudacacia L.). Type locality : Topeka, Illinois. In the coloration of the wings, this species resembles ^E. vittatus Haliday and ^E, kuwanaii(&\v !) Moulton, which occur, respectively, in Europe and the Pacific coast region of. North America. From both it may be known by the longer head, shorter prothorax, and the details of wing coloration. In ad- dition to these characters, it is also to be noted that in ku- ivanaii only the third antennal segment is white, the spine- bearing sense area on the ventral surface of the fifth antennal segment is circular in form, the head is not emarginate in front, and, rhost important of all, the ninth abdominal segment of the male is provided with lateral claspers. ^olothrips crassus, new species.

Maxillary palpi three-segmented; labial palpi four-segmented. Prothorax about two-thirds as long as greatest width, distinctly broad- ened behind. Mesothorax a little less than 1.4 times as broad as prothorax, anterior angles broadly rounded; mesoscutum very closely transversely striate. Metathorax with sides roundly converging posteriorly; meta- scutum subreticulate. Wings of fore pair moderately slender (about seven times as long as width at middle), slightly narrower in basal third; venation normal, or with the lower subapical cross-vein wanting; anal half of wing traversed by a longitudinal black band which extends from the basal fifth to the tip of the wing, becoming paler and narrower at apex, and, in the second fifth, broadened to nearly the costal margin; hind wings grayish. Legs short and stout, the fore femora oiily about one and one-half times as long as wide. Abdomen stout, of normal structure. Measurements of holotype: Length 1.55 mm.; head, length 0.162 mm., width 0.209 mm.; prothorax, length 0.168 mm., width 0.264 nun.; meso- thorax, width 0.360 mm.; abdomen, width 0.432 mm. Antennal segments : 1, 36 M; 2, 54 n; 3, 92 M; 4, 90 M; 5, 57 M: 6, 14 M; 7, 14 M; 8, 14 »; 9, 14 M; total length of antenna, 0.39 mm., width at segment 4, 0.030 mm. Described from one female, taken on Plummer's Island, Maryland (in the Potomac River near Washington, D. C.), May 19, by W. L. McAtee and the writer. It was found in a flower of Hydrophyllum rirginicnin L. This species, like the preceding, is related to fcHU'inutii and vittatus. From the former it may be known by the white fourth antennal segment and the stouter facies; from the lat- ter its separation is more difficult, judging from the brief pub- lished descriptions, but should be distinct by the longer seg- ments 5-9, which together are fully a fifth longer than seg- ment 3, instead of subequal to it as in vittatus. The lat- ter is known only from England, Finland, Sweden, and Austria- Hungary (Dalmatia). With the specimen above described, I have doubtfully as- sociated another female, taken on a conifer at Urbana, Illinois, May 21, 1908, by J. V. Bopp, then a student in the University of Illinois. It agrees with the type in most respects, but the third antennal segment is slenderer and darkened at tip, the basal transverse band on the wing is complete, and :i second band shows a tendency to appear near the apex of the wing, just basal to the apical seventh. 132 PROCEEDINGS ENTOMOLOGICAL SOCIETY FAMILY THRIPID^ HALIDAY. Genus MEROTHRIPS nov. (/xijpos, the femur; Qprf, a wood worm.) Head rather elongate, anteriorly obtusely angulate, with a pair of long bristles on dorsum between eyes and antennae. Eyes (in the type species) greatly reduced; ocelli wanting. Antennae long, approximate, eight-seg- mented, moniliform, inserted on ventral surface of head; segments 3 and 4 with sense areas (instead of sense cones) at apex; segment 8 elongate, fusi- form. Mouth cone equal in length to face, semicircularly rounded at apex; maxillary palpi three-segmented; labial palpi two-segmented. Protho- rax trapezoidal, broader than long and somewhat longer than head, with a pair of subparallel longitudinal sutures separating the notum from pleu- ron and coxa; posterior angles with a single long bristle. Legs very stout; metacoxee separated by less than their own diameters; mesocoxae separated by an interval thrice as great; fore and hind femora greatly enlarged; male with a broad subbasal tooth on inner margin of fore femur and with a long, stout tooth on inner margin of fore tibia at tip. Abdomen moderate- ly slender, exceedingly blunt at tip, the apical segments very transverse and with long, weak spines; ovipositor greatly reduced, certainly function- less; abdomen of male without ventral sensory areas and without strong, chitinous projections on apical segments. Type,: Merothrips morgani, new species. In the weakened, pale cuticula, reduced organs of vision, enlarged femora, and functionless ovipositor, the whole in- sect shows a remarkable adaptation to life under bark and in other similarly secluded places — a habit until now wholly un- known among the Thripidse. The affinities of such an anoma- lous genus may be thought open to speculation, but, in our present arrangement of the genera of this, family, it seems to take a natural position just after Chirothrips. The ancestors of this form were almost certainly Chirothrips-\\\i£ Thripi- dse which, originally passing only the winter under bark, became gradually adapted to that method of life as a fixed habit, through finding there suitable food and adequate protection, both from enemies and unfavorable climatic conditions. The loss of the ovipositor is easily explained, for, as in the Tubu- lifera, there is no need to hide the eggs in plant parenchyma to avoid their being injured, because under bark may be found safe hiding places in plenty. Merothrips morgani, new species. (PI. V, figs. 1-3.) Female. — Length about 0.8 mm. Color pale grayish yellow, gray, or brown, with head, legs (especially the anterior pair), and first two antennal segments suffused with yellow.

FAMILY PHLCEOTHRIPID^E UZEL. Zygothrips pallidus, new species. (PI. VI, figs. 1, 2.) Female (forma brachyptera). — Lengthabout 1.6 mm. Color clear, bright lemon-yellow, with antennal segments 7 and 8 shaded with brown, and apical three-fourths of tube abruptly nearly black. (By reflected light the legs and antenna? appear darker, due to the absence therefrom of the yellow hypodermal pigment, which is very dense in the other regions of the body.) Head about 1.4 times as long as wide, very slightly broadest at basal fourth, thence evenly narrowing to eyes and base; vertex elevated, al- most overhanging, evenly declivous; dorsal and lateral surfaces without sculpture, the spines few and very inconspicuous; postocular bristles short, two-thirds as long as eyes, blunt but not capitate. Eyes about one-third as long as head, slightly protruding, nearly prominent. Anterior ocellus scarcely overhanging, the posterior pair opposite anterior third of eyes.

Mouth cone blunt, much shorter than width of head, reach- ing about to middle of prosternum; labrum not attaining labium. Prothorax about as long as width of head and (inclusive of coxae) about one and two-thirds times as wide as long; surface smooth; anterior marginal and midlateral bristles wanting, others short and blunt (scarcely capitate), the two pairs near the posterior angles subequal in length and longest; coxal bristle similar to and nearly as long as thelatter. Pterothorax slightly wider than prothorax, sides nearly straight and parallel. Legs rather stout, of moderate length; fore tarsi armed with a very small, acute tooth; color lemon-yellow, without shading even on femora. Abdomen (greatly distended in the type) of apparently normal form. Tube about half as long as head, less than twice as long as basal width, and about half as wide at apex as at base; terminal bristles "brown, very slightly longer than tube; all other abdominal bristles clear yellow.

Male. — Much smaller than female; length about 1 mm. Color luteous, shaded with gray on femora, tibia?, segments 4-8 of antennae, and apical three-fourths of tube. Ocelli apparently wanting. Prothoracic bristles rather more capitate than blunt. Abdomen slender. Otherwise similar to female. Described from 1 female (holotype) from Brownsville, Texas, taken December 8, 1910, in sweepings from Bermuda grass; and 1 male (allotype) from Padre Island, Texas (oppo- site Point Isabel), taken June 28, 1908, "in sweepings from grass, etc." Bo_th specimens were taken by Mr. Hart. The coloration of this species is remarkable, as is also the structure of the third antennal segment. It will be noticed that the two illustrations given herewith are unfortunately of the male, for the reason that the female was not known until two years after the execution of the drawings. Genus RHYNCHOTHRIPS nov. s, beak; Op^, a wood worm.) Head little, if any, longer than broad, about equal in length to prothorax; cheeks finely roughened, without spiniferous tubercles. Antenna? eight- segmented, the last two segments closely united. Eyes one-third or one- fourth as long as head. Ocelli placed far forward, the median one overhang- ing, sometimes borne at tip of slightly produced vertex. Mouth cone unusually long and slender, fully as long as dorsum of head, attaining or surpassing front margin of mcsosternum; lab rum very acute, elongate, sometimes one and one-third times as long as width of head.

This genus will also embrace Trichothrips tridcntatus Shu 11 and T. buff a Hood. The very long mouth cone and the large, heavy prothorax are distinctive. Though two of its species were described in Trichothrips, it appears to be much more closely related to Liothrips. All the known species occur under 142 PROCEEDINGS ENTOMOLOGICAL SOCIETY the loose scales of bark on living trees, and the peculiar mouth- parts appear to be an adaptation to such a life.

OF WASHINGTON, VOLUME XIV, 1912. 143 Described from 4 females and 9 males, from Carbondale, Pulaski, Riverside, and Urbana, Illinois, taken in May, June, July, September, and October, by L. M. Smith, C. A. Hart, and the writer. It occurs commonly under the loose scales of the bark on wild cherry, though taken occasionally from peach and sycamore. It is closely related to the species described by me asTric/io- thrips hnjfce, but the smaller size, longer, stouter prothorax, wider head, and stouter, differently colored antennae, should distinguish it at once. Franklin's record1 of the latter insect for St. Anthony Park, Minnesota, may possibly refer to the present species. Rhynchothrips dentifer, new species. (PI. VI, fig. 3.) Female (for ma macropf era). — Length about 1.5 mm. Color dark black- ish brown, nearly black; tarsi and intermediate antennal segments paler.

Wings apparently broad, of equal width throughout, slightly clouded with brownish at middle. Legs of medium length, the fore femora equal in length to head; fore tarsi armed with a short, stout tooth placed at right angles to the tarsus. Abdomen large, broad, nearly 1.4 times as wide as prothorax, narrowing roundly from about segment 4 to base of tube.

Described from two females taken by the writer near Bald- win, Michigan, under loose bark on a freshly-cut poplar stump, August 16 and 17, 1908. The remarkably long mouth cone and the armed fore tarsi render this species very distinct. Genus PHLCEOTHRIPS Haliday. 1836. Phlaothrips (sic!) Haliday, Ent. Mag., vol. in, p. 441. 1895.

The species coriaceus of Haliday must be considered the type of this genus, for it is the only recognizable one known to Haliday which has not been removed or reduced to synonomy. Its North American components — with the exception of zv'/- tatus and maculatus — form a homogeneous group remarkable for the structure of the fore leg of the male, the femur having two acute teeth on the inner side near the apex, between which when the leg is flexed, fits a similar tibial tooth. This struc- ture is constant in more than a dozen species known to me, OF WASHINGTON, VOLUME XIV, 1912. 145 and entitles them to rank as a distinct subgenus, which may be distinguished from Phlccothrips spp. as follows : Subgenus HOPLANDROTHRIPS nov. Dorsal surface, at least of pronotum, not deeply roughened. Vertex subconical, more or less produced. Genal spines not directed anteriorly from the apices of prominent tubercles. Prothorax evenly trapezoidal, with straight sides; bristles long, normal in position. Femur of male with two subapical teeth on inner side; tibia of male with a similar tooth near base. Type: Phlceothrips ^Hoplandrothrips) xanthopus, new species. BagnaH's Acanthothrips bidens almost certainly belongs here, if it is not the original Hoplothrips corticis Amyot and Serville. In the latter event Hoplothrips will, of course, have priority over Hoplandrothrips. Phloeothrips ( Hoplandrothrips) xanthopus, new species. (PI. VI, figs. 6, 7a, b.)

Described from 5 females, as follows: Pulaski, Illinois, C. A. Hart, May 28, 1909, in sweepings from grass; Pulaski, Illinois, July 24, 1909, C. A. H., in woodland sweepings; St. Joseph, Illinois, May 4, 1907, C. A. H. and J. D. H., at base of mullein leaves; Urbana, Illinois, January 26, 1908, J. D. H., under bark of soft maple tree; "Millerstown, Pa., Sept. 6, on fox grape." (Pa. State Dept. Agr., Div. Zool., No. 3668). Two males, both from Illinois, appear to belong with this species, but show so much mutual variation in the form of the fore legs that I have hesitated to include either in this pre- liminary description. The species bears a resemblance to Hinds's uzeli, but is easily separable by the much shorter tube (which is not more than 0.6 as long as the head, instead of nearly 0.8) and the longer, slenderer, and less abruptly sinu- ate, third segment of the antenna, which in uzeli is not more than 1.7 times as long as wide. This latter difference is illus- trated in the accompanying figures (Pl.vi, figs. 5 and 6). Phlceothrips ( Hoplandrothrips) juniperinus, new species. (PI.

Described from 4 females and 2 males, taken by the writer from branches of red cedar (/untperus Virginian a L.), on Plummer's Island, Maryland (in the Potomac River near Washington, D. C.), May 19, 1912. The coloration of the antennae, taken in conjunction with their structure and the form of the head, would seem to indi- cate a very distinct species. It belongs, however, to a group in which specific separation is largely opinionative. Phloeothrips(Hoplandrothrips) funebris, new species. (PI. VII, figs. 1-4.)

This is an anomalous member of its genus, and may easily be known by the rounded vertex, the peculiarly shaped head 152 PROCEEDINGS ENTOMOLOGICAL SOCIETY with a pair of long, knobbed bristles on dorsum, and by the number and disposition of the sense cones. It approaches the genus Crvptothrips in several points of structure. The male is of special interest in that the postocular bristles, instead of those at the anterior prothoracic angles, are increased in length, which is in marked contrast to a reverse tendency shown in the other species.

Eyes about one-fifth as long as head, subcircular as seen from above. Ocelli of moderate size, equidistant; anterior ocellus borne at tip of vertex, posterior ocelli opposite or in front of centers of eyes.

Described from one female taken on elm at Dubois, Illi- nois, July 3, 1909, by Mr. Charles A. Hart. The unarmed fore tarsus, if constant, is a remarkable charac- ter, occurring nowhere else in the genus. The sculpture of the head, the pedicellate last segment of the antenna, the slender tube, and the coloration of the legs, all tend to make this a very isolated species. Genus CRYPTOTHRIPS Uzel.

Smith; Parker, July 14, 1909, 1 female, on hickory branch, C. A. Hart. Though resembling C. carbonari tts in the elongate head and the arrangement of the cephalic and prothoracic bristles, this species is of quite different appearance and much smaller size. In carboiiarius, of which the female is unknown, the fore femora of the winged male are about 0.8 as long as the head, which is about equal to the length of the first five antennal segments; in the present species the femora of the male are less than 0.6 as long as the head, and the latter is distinctly shorter than the first five antennal segments. Gryptothrips exiguus, new species. (PI. vin, fig. 4.) Female (forma macroptera}. — Length about 1 mm.

Described from 1 female taken in sweepings at Grand Tower Illinois, July 12, 1909, by Mr. Charles A. Hart. This species is abundantly distinguished by its small size, the form of the antennal segments, and the long, blunt, post- ocular and prothoracic bristles. In several respects it shows an interesting approach to the genus Phlccolhrips. 156 PROCEEDINGS ENTOMOLOGICAL SOCIETY Genus GASTROTHRIPS iiov. ip, the abdomen; Opffi, a wood worm.)

Pronotum shorter than head, trapezoidal, twice as broad across posterior angles (inclusive of coxae) as median dorsal length; posterior and anterior margins concentric. Legs moderate; fore tarsi sometimes armed. Wings, when present, slender, not closely fringed, without double subapical fringe on posterior margin. Abdomen moderate or heavy; tube short to medium, more or less abruptly constricted at apex. Type: Gastrcthrips ruficanda, new species. As above defined, this genus will prove a moderately large one, comprising species which for the most part live under bark — principally, it seems, in the southern States. In ad- dition to the two species herein described as new, two or three others are known to me from uniques. All resemble the spe- cies of Cryptothrips in no slight degree, especially in the form and structure of the mouth cone, antennae, and eyes. They constitute, however, a distinct type of radically different fades, recognized at once by the shorter head and the abruptly con- stricted tube. Gastrothrips ruficauda, new species. (PI.

(Diptera, Leptidse.) BY FREDERICK KNAB and R. A. COOLEY. When preparing his paper on blood-sucking Leptidsc* the senior author was unable to find more than the single original observation, by Osten Sacken, of the biting habit in Sympho- romyia. As the result of conversation, during the last meet- ing of the American Association for the Advancement of Science, and subsequent correspondence, Professor Cooley sent him specimens taken in the act of biting, together with the notes reproduced below. Three specimens with the number 143 attached, taken at Sedan, Montana, July 1, 1906, are all females of the same species. The material came to hand too late to be incorporated in the above-mentioned paper. As it is evident that the blood-sucking habit in Sympho- romvia is confined to certain species, perhaps a single one, the determination of specimens that have actually bitten is of con- siderable interest. There was some difficulty in determining the specimens, as it proved that Symphoromyia is systematically in a rather unsatisfactory condition. However, the specimens fit very well the description given by Williston for the female of his Symphoromyia pachvceras. The proximity of the two regions, northern California for Williston's specimens and southwestern Montana for Professor Cooley's, make the agree- ment reasonably probable. Whether Osten Sacken had the same species under observation probably can only be deter- mined by examining the original specimens, if these are still in existence. We have been unable to trace the locality, Webber Lake, California, given by Osten Sacken, and, moreover, we know very little of the distribution of the species of Sympho- romyia. Attention must be called to the fact that the specimen standing as S. packvceras in the National Museum collec- tion, and upon which Coquillett based his diagnosis, are not Williston's species. This is evident from the shining black ab- domen. Williston describes his species as "gray pollinose," indicating this condition for both thorax and abdomen; in this the Montana specimens agree. The color of the third an- tennal joint, palpi, and legs, which have been freely used in differentiating the species of this genus, are, as might be ex- pected, subject to some variation which probably depends not only upon age, but also upon food. There is considerable diversity in the mouth-parts of dif- ferent species of Symphoromyia. The specimens taken by the junior author have rather short mouth-parts with a broad, "This volume, pp. 108-109. 162 PROCEEDINGS ENTOMOLOGICAL SOCIETY fleshy labial sheath which evidently can be retracted, similarly to the sheath of mosquitoes; this sheath is very thick at the sides and there is a central depression in which the other mouth- parts lie. The piercing parts are strongly chitinized and the maxilla? are clothed on their ventral surfaces with minute stiff hairs which on the apical half become transformed into barbs, densest and stoutest at the apex. In Symphoromyia crnenta Coquillett the mouth-parts are much longer, the labial sheath much more slender, apparently for the most part well chiti- nized, and closely surrounds the other parts, which are only exposed through a narrow dorsal slit. The maxillae are smooth to near the apex, where there is a dense group of strong barbs. Coquillett in his "synopsis" already indicated this difference, but used the erroneous and misleading term "labella" to in- dicate the mouth parts. It has been thought advisable to keep Professor Cooley's notes on Symphoromyia pachyceras intact, and they follow herewith over his own signature. -FREDERICK KNAB, We have repeatedly taken a species of Symphoromyia in the act of taking blood. They have always attacked me on the hand and they inflict a painful wound. The first time I was bitten by one I slapped with the same caution that I would a mosquito, lest it should escape, but I soon learned that this is unnecessary, for one can pick them up with the fingers as he would an inert object. In fact, you may poke them around with the finger without causing them to fly. They come and alight almost silently and generally come singly. Our note on this species is as follows : NOTE 143. — Troublesome blood-sucking fly. Causing swel- ling. Very painful. Fly is silent when alighting. It is my impression that this is distinctly a mountain form; that is, we do not find it in our large open valleys, but only in mountainous places. — R. A. COOLEY. OF WASHINGTON, VOLUME XIV, 1912. 163 SIX NEW GENERA OF NEARCTIC MUSCOIDEA. BY CHARLES H. T. TOWNSEND. The following six new genera are erected for as many de- scribed North American species, which can not be placed in any previously erected genera known to me. The reproductive habits of four of these genera are known, and these four are treated in a forthcoming paper on the female reproductive system, eggs, and early stages of muscoid flies. Neophorocera, gen. nov. Erected for Phorocera edivardsii \V ill. (Euphorocera claripennis Coq. pt.). The male has the second antennal joint hardly at all elongate, while the female had it noticeably so. The length of the second antennal joint thus becomes a secondary sexual character in this genus, which is the first case of the kind known to me in this immediate group. In the salmaciine and belvosiine flies the same secondary sexual character of the second antennal joint is much more pronounced. Reproductive habit, oviposition of flattened macrotype egg on host. The egg-chorion is honeycomb-reticulate and without operculum. The uterus is absent, but the uterovagina of one of the dissected specimens (TD394) showed an egg containing a fairly developed maggot. This development of the maggot in the uterovagina is probably exceptional, due to undue retention of egg from failure to find a suitable host. (TD394, coll. by D H. demons, Aug. 22, 190S, Melrose Highlands, Massachusetts, and determined by W. R. Thompson as Euphorocera claripennis Coq.). Type: Phorocera ed-wardsii Will., Scudder's Butterflies of New England, vol. in, p. 1921. The genera Exorista, Tricholyga, Euphorocera, andC/ueto- tachina have the egg-chorion without reticulation and fur- nished with an operculum at the cephalic end. \Vinthciuia appears to lack both reticulation and operculum. C/ueto- lyga and Nemorilla appear to have the chorion reticulate and without operculum, but are at once distinguished from Neo- phorocera by their ciliate hind tibiae. Euacemyia, gen. nov. Erected for Acetnyia tibialis Coq. The frontal bristles stop at base of antennae, the vibrissa- are inserted well above oral margin, the third an- tennal joint of female is only about one and one-half times as long as second, the cheeks of female are only one-fifth of eye-height, the apical cell is open and ends well before wing-tip. In Acemyia the frontal bristles descend nearly or quite to base of third antennal joint, the vibrissae are inserted practically on the oral margin, the third antennal joint of female is fully or more than twice as long as second, the cheeks of female are over one- 164 PROCEEDINGS ENTOMOLOGICAL SOCIETY third of eye-height, and the apical cell ends almost in wing-tip. The macrochaetae of abdomen are only marginal in both genera. Reproductive habit unknown. Type: Acemyia tibialis Coq., Rev. Tach., p. 116. Acemyia acuticornis Meig. had been reared in Europe from Acridium, Acemyia dentata Coq., which is not at all typical of the genus, having the apical cell closed and ending well before wing-tip, and the eyes in female descending almost to the level of the vibrissae, has been reared in North America from Melanoplus and Chortophaga. Doryphorophaga, gen. nov. Erected for Lydella doryphorcs Riley. It belongs with the compsi- lurine flies, and bears a strong general resemblance to Compsilura con- cinnata. The eyes are thickly hairy, the facialia are ciliate on about lower two-thirds, the bend of fourth vein is without stump or wrinkle, the intermediate abdominal segments bear discal bristles, and the ventral carina and curved spine-like piercer, both of ordinary character, are present in the female. It differs from Compsilura principally in having the second antennal joint noticeably elongate, and the parafacials widened. Differs from Lydella and De.rodes in the thickly hairy eyes, ciliate facialia, and frontal bristles not descending low; from Incamyia in the last character and the ordinary ventral carina; and from Eucelatoria in the hairy eyes and the elongate second antennal joint. Reproductive habit, subcutaneous larviposition in host. The uterus is long, slender, and coiled, and develops white maggots in single file to the number of about 150. The maggot has well-developed rows of micro- scopic spines, of which the first three rows and the last row encircle the body, the intermediate six rows being on ventral surface and about half encircling the body. (TD370, coll. by D. H. demons, Aug. 17, 1908, Melrose 'High- lands, Massachusetts, and determined by W. R. Thompson as Phorocera dorypliorje. Type: Lydella doryphora Riley, First Report, Insects of Missouri, p. 111. The type species has been repeatedly reared from the larvae of Leptinotarsa (Doryphoni) decemlineata in the northern and eastern United States as far west as Missouri. Neadmontia, gen. nov. Erected for Adtnontia limata Coq. Whole body strongly bristly. The true frontal bristles are numerous, strong and stop at base of antennae; a row of closely placed weak bristles runs diagonally down the parafacials below end of frontal row, but is not a true continuation of the latter. Facilia not ciliate. Arista very delicately pubescent. Third antenna! joint a OF WASH! ">N, VOLUME XIV, 1912. 165 little concave on upper (front) edge, the upper (front) terminal angle more or less produced into a short blunt tooth. Abdomen with discal and mar- ginal macrochaetse. Apical cell closed almost at wing-tip. Reproductive habit unknown, but probably larviposition. Type: Admontia liniata Coq., Proc. U. S. Nat. Mus., vol. xxxv, p. 105. Coquillett's interpretation of the genus Admontia is a complex. His Ad. dcmylus is evidently one of the compsilurine flies, as indicat"d by the statement in description that the abdomen of female is thickly beset with short spines on under- side of third and fourth segments. It parasitizes Cophyrus larvae. It is possible that his Ad. retinue, described from males only, is an Actia. His Ad. polita probably belongs to the present genus Neadmontia. His Ad. pergandei and degeer- ioides seem to fit the genus Admontia. His Ad. setigera (San Mateo County, California, specimen) is a different genus from all of these. It lacks discal abdominal bristles, and bears on parafacials a true continuation of frontal bristles in a row extending to lower border of eye, all the frontal and parafacial bristles being of equal strength at root. This California specimen is a female and shows no ventral carina. Specimens determined by J. A. Hyslop as Admontia per- g-audeiCoq.were reared by him from larva? of Tipula infii scuta, Jackson, Tennessee. Nineteen flies issued from October 7 to 14, 1908. A reared female was found by Hyslop to contain 103 elongate eggs. The genus is recorded as parasitic in larvae of Tipulidse in Europe. The female probably deposits maggots on the surface of the soil, and these penetrate later in search of the tipulid larvae. TD389, collected by D. H. demons, August 21, 1908, North Saugus, Massachusetts, and determined by W. R. Thompson as Admontia degeerioides Coq., showed a slender uterus containing about 55 eggs and maggots similar to those of the compsilurine flies in general appearance. Female without piercer, with discal abdominal bristles, ciliate facialia, long, slender third antennal joint, and apical cell ending near wing-tip. Oxexorista, gen. nov. Erected for Exorista eudrya Towns. This has the general external characters of Sisyropa. But until the female of Tachina thennophila Wied. of Java (type of Sisyropa)\s dissected, we shall not be able to say what the genus Sisyropa is. Eumasicera coccidella Towns, has apparently the same general external characters as T. therwophi/a\\<\., and the female fly is almost indistinguishable externally from the female of Sisyropa hemerocampa; Towns. Yet the last (TD387, Gip. Moth Lab. 1976) deposits 166 PROCEEDINGS ENTOMOLOGICAL SOCIETY elongate white maggots on or near host, while the first (TD388, Gip. Moth Lab. 1975) deposits black microtype eggs on foliage. Thus Sisyropa may have either one of these habits, or perhaps still a different one. Sisyropa hemerocampceTowns. (syn.of Exorista amplexa Coq.,acc. W. R. Thomp- son) probably does not belong to the present genus. Its egg shows no 8ign of pedicel, while the dissected eggs of Exorisfaeudryce(TT)'&Q5)$\wyfedL an atrophied pedicel. It is most probable that Sisyropa hemerocampce Towns, is congeneric with T. thermophila Wd., since both have the front very narrow, the cheeks and especially parafacials extremely narrow, and the eyes thickly hairy. Reproductive habit, larviposition of white maggots on or near host. The maggot is fat, with 13 wide and complete rows of microscopic spines encircling the body, the spines somewhat weaker dorsally. The sperma- thecal ducts are elongate and doubled on themselves. Uterine capacity up to 200 or 300 eggs and maggots. (TD395, collected by D. H. demons, Aug. 22, 1908, Melrose Highlands, Massachusetts, and TD425, collected by F. B. Lowe, August 29, 1908, near Swampscott, Massachusetts; both determined by W. R. Thompson as Exorista eudryce Towns. Type: Exorista eudryce Towns., Trans. Am. Ent. Soc., vol. xix, pp. 287-288. Euexorista, gen. nov. Erected for Exorista futilis O. S. This has the general external char- acters of Parexorista, and was referred to that genus by B. and B.. along with the host of other species of various reproductive habits. Thus B. and ^sParexorista is another mixed-reproduction genus. The present form has no discal bristles on intermediate abdominal segments, and the hind tibiae are ciliate. Reproductive habit, leaf-oviposition of black microtype eggs. Uterine capacity up to 2,000 or 3,000. Chorion with a low power shows a beaded net-like design, the bead strings running from pole to pole and more or less interlaced into a network; with high power (oil immersion) it shows a structure composed of a microscopic network of chitin, the lines of chitin being much narrower than the open spaces between them. (TD361, August 15, 1908, Spot Pond, near Melrose, Massachusetts, and TD344 August 13, 1908, North Andover, Massachusetts; both collected by D. H. demons, and determined by W. R. Thompson as Exorista futilis O. S.) Type: Tachina (Exorista) futilis Osten-Sacken, Can. Ent., vol. xix, p. 161. It appears from the descriptions that this species can not belong to Epimasicera, type Tachina ivestennanni Zett. (syn. of Tachina mitis Meig., ace. Thomson, Bezzi and Stein), since this genus has two pairs of median discal macrochaetae each on second and third abdominal segments and the hind tibiae are not ciliate. OF WASHINGTON, VOLUME XIV, 1912. 167 THREE NEW NOCTUID^. BY HARRISON G. DYAR. Arenostola orphnina, new species. Gray, over soiled ocherous, generally evenly suffused with gray, nearly obliterating the markings. In specimens with little suffusion all the veins are dark-lined and a row of dark points on the veins represents the outer line; a small white speck at the origin of vein 3; a row of terminal black dots between the veins; a gray shade along costa and from median vein outward, these shades darker than the rest of the wing also in suffused specimens. Hind wing pale gray. Expanse, 27 to 32 mm. Four males, three females, Hampton, New Hampshire, August 1, 1911 (S. A. Shaw). Type: No. 15098, U. S. National Museum. A robust species like inquinata Guene"e, but still larger and longer- winged. The veins are dark-lined as in dejecta Grote. Paracretonia, new genus. Falls in the Erastriinse. Fore wing with vein 9 from 10 anastomosing with 8 to form the areole; frons with rounded prominence, roughened, with a plate below; fore tibise un- armed; abdomen without crests; hind wing with vein 5 well- developed from well below middle of discocellulars; eyes large, round; palpi upturned. Paracretonia xithon, new species. Fore wing light gray, with an almost whitish ground, shaded with black- ish gray; a broad dark oblique inner band from costa to claviform; an ocher- ous elongate mark below; spots white-filled, orbicular round with black dot and ring, reniform constricted, with black spot in lower half, claviform rather large; an oblique white shade before apex; outer line oblique, double, blackish, followed by an ocherous band in which gray rays project along the veins; a marginal row of dark dots. Hind wing fuscous with white fringe. Expanse 21-22 mm. Three specimens, La Puerta Valley (near San Diego), Cali- fornia (G. H. Field). Type: No. 15112, U. S. National Museum. This may. prove to be the same as Phyllophila aleptivoides Barnes and McDunnough (Can. Ent., XLIV, 217, 1912). Sacadodes, new genus Antennae bipectinate, the branches moderate in the male, short in the female, ciliate. Palpi porrect or oblique, the second joint long, thick; third short, nearly globose in the male, long and slender in the female. 168 PROCEEDINGS ENTOMOLOGICAL SOCIETY Tongue undeveloped. Eyes large, naked. Front with roughened tuber- cular prominence, angular in outline. Tibia? rather densely hairy, with- out spines. Thoracic vestiture hairy, prothorax slightly crested, meta- thorax with thick divided crest; abdomen with small crest at base. Fore wing with vein 9 from 10, anastomosing with 8 to form the areole; 7 from near end of areole. Hind wing with vein 5 strong, from well below middle of discocellulars. Retinaculum of male broad, not bar-shaped. Said, to be near Diparopsis Hampson, which has vein 5 of the hint! wing weak and arising near middle of discocellulars, according to Hampson's description and figure. In the present form vein 5 seems scarcely at all weaker than the other veins. Sacadodes pyralis, new species. Fore wing clayey ocherous to purplish brown; basal and subterminal spaces darker, olivaceous brown; a narrow dark discal mark; lines lighter, the inner edging the basal dark area, angled below median vein; outer slightly curved, with a narrow dark inner edging; subterminal line straight, near and similar to the outer line. Hind wing whitish in the male, purplish brown in the female. Expanse, 30 mm. Two males, one female, Trinidad, British West Indies, bred from the "pink cotton-boll worm" (P. L. Guppy). Tybe: No. 15113, U. S. National Museum. Both in markings and structure much like Diparopsis, cas- tanea Hampson, which is destructive to cotton in South Africa. The larva is cylindrical, robust, the segmental incisures strong. Head moderate, its vertex within joint 2. Cervical shield and anal plate well chitinized. Skin smooth; tuber- cles and setie small, normal. Abdominal legs equally devel- oped. The mature alcoholic specimen is colorless; a smaller one is marked with pink in dorsal and stigmata! bands, row of oblique subdorsal dashes and narrow subventral line. Mr. Schaus kindly examined a specimen and consulted with Mr. Paul Dognin and Sir G. F. Hampson. Mr. Dognin has specimens of the species from Argentina and the one that Mr. Schaus examined was from Venezuela. The distribution of the species is therefore extensive. The new name was communicated to me by Mr. Schaus, having been suggested, I understand, by Sir G. F. Hampson. OF WASHINGTON, VOLUME XIV, 1912. 169 MORE ABOUT THE SLOTH MOTH. (Lepidoptera, Pyralidse.) BY HARRISON G. DYAR. Some time ago I described a pyralid from the fur of the living sloth as Cryptoses clwhvpi (Proc. Ent. Soc. Wash., ix, 142, and x, 81, 1908). At the time I overlooked the descrip- tion of a sloth moth by Spuler as Brachypodicola hahneli. The English entomologists have concluded that these two forms were the same species and I have lately received speci- mens of rny species positively labeled with the name of Spuler's. However, I am now satisfied that there are at least three sloth moths, each referable to a distinct, though allied, genus. Of Cryptoses cholcepi I have now 30 specimens, 19 males and 11 females, received through the kindness of Mr. William Schaus from different parts of Costa Rica. The sexes differ in venation, in wing shape, and in the distinctness of the mark- ings. The figure of the venation given by me (Proc. Ent. Soc. Wash., ix, fig. 9) is that of the female. The male differs in lacking entirely vein 11, there being only one free vein and three stalked veins from the upper angle of the cell. The wings of the male are more sharply pointed than those of the female. The markings which I described (Proc. Ent. Soc. Wash., x, 81) are those of the male. Those of the female are duller, the pale streaks less contrasted. The moths vary con- siderably in size in both sexes. The three original types are all females. Of Bradypodicola hahneli I have not obtained any material. A study of Spuler's article, however, shows its distinctness from the above. Spuler figures the venation of the male. In it vein 2 is shown stalked with 3-5, while in Cryptoses it arises well before the angle of the cell; vein 6 also in Brady- podicola arises further below the angle of the cell than in Cryptoses. But these are minor differences, while in general the venation is alike. However, the shape of the head is very different. In Bradypodicola it is very prominent at the vertex in side view, the front being concave. In Cryptoses the vertex is very slightly prominent and the front continuously convex. The occurrence of a third form strengthens the above con- clusion of the distinctness of Bradypodicola and Cryptoses. This third form is from Brazil, and I have before me a female specimen sent by Dr. R. von Ihering. Doctor von Ihering will name and describe it, so I will not enter into its discussion at present, otherwise than to say that it differs from both the 170 PROCEEDINGS ENTOMOLOGICAL SOCIETY above in venation, while the shape of the head is more like Bradypodicola than Cryptoses. Crpytoses cholcepi comes from Central America and Pana- ma, where it lives in the fur of the sloth Cholcepiis. Brady- podicola hahneli comes from Brazil, where it lives in the fur of the sloth Bradypus. Of the habits and distribution of the third species we shall be enlightened later by Dr. von Ihering.

Mr. Claude Morley has favored the entomological world with another volume of his Ichneumonologia Britannica, being volume iv of his British Ichneumons, Tryphoninse, and set forth in text and figures comprising pages i-xvi, 1-344, one plate, and many figures. Th,is compilation will no doubt be consulted by many a student of insects and not vainly, for a mass of facts has been painstakingly gathered and arranged, while some genera have been figured that have previously been known to science only by descriptions. In view of the circulation that the present book is likely to have, it is the more unfortunate that the author did not lay down his work more securely, as, for example, with reference to the genera there is an evident disregard as to foundationstones. Forty-nine genera are treated, of which one is a newr genus, and a blanket genus at that, including a number of old genera that by some writers have been regarded as good and distinct. The new genus is Homocidus and is evidently a mixture of many species belonging to Zootrephes, Syphoctonns, and ffomotropus, and possibly Ein'zemnm and Aniarophrov. If these genera are to be fused then Zootrephes must be used and a new genus is uncalled for. For the present Homocidus Morley, for which I designate Hor.iocidns r/Vffff/s Gravenhorst as type, sinks as a synonym of Homotropus (Foerster) Davis, for which latter I designate Bassus bzcapt'llarisW&lsh as type. In the table of genera Homocidus is represented as wanting notauli, but in the table to species under the same genus are to be found two categories, one with notauli present, the other with notauli wanting ! Bassus is credited to Fallen instead of Fabricius, who erect- ed the genus. According to Curtis's fixations of types Bassus Fabricius can not be used for Bassns Authors, which latter should be called .\uonialon J urine. Anomalon Authors being without a name may be called Paranomalon new genus, with Op/iion flarifrons Gravenhorst as type. The type of Acrotowus Holmgren has never been fixed, so Trvphoii Incidnlns Gravenhorst is1 hereby designated as type. Addognathus Holmgren : No type designated.

Fortunately, the fact that Mr. Morley did not concern him- self with the foundation stone or genotype of each genus us»-d by him does not change the status of his concept- in many cases, ;t> quite frequently the constituents of his generic con- cepts include the genotype of the genus involved. However. in such a painstaking effort as this, one would look for the finality that can come only through the consideration of geno- types, especially in view of the fact that some of the earliest writers from Latreille on recognized the necessity of definite premises upon which to argue the case of the ichneumon flies. The compilation of biological records i.< apparently exhaus- tive and will serve a useful purpose in the hands of the field worker and economist. The classification of the Tryphoninse as here set forth is admittedly no improvement over Holmgren's >y>tem. except in the acceptance (,f an additional tribe based on pectination of claws. Segregates of some of the older, heterogeneous genera, ac- cepted by colleagues of the author, are suppn-.-id. as in the 178 PROCEEDINGS ENTOMOLOGICAL SOCIETY case of the Bassini, while the conformation of the scape in one case and the character of the claws in another is drawn upon to separate tribes. So we have the time honored incon- sistency of treatment repeated. While we could have wished to have the subject treated from some new viewpoint, yet the result will be of value to all stu- dents of this group, no matter what fauna is considered, es- pecially in view of the treatment of a number of species that are genotypes of widely distributed genera and the introduc- tion of so many good figures wThich act as a guide to the habi- tus in a group where habitus is so important in introducing the uninitiated to the study of the group.

BRUES, Bussey Institution, Harvard University. I have been much interested in the summary published in the last number of the Proceedings of the Entomological Society of Washington (vol. xiv, pp. 79-81, April-June, 1912), of re- marks by Dr. Frederick Knab relative to the transmission of human diseases by blood-sucking insects. He has called attention to the fact that such insects must be rather constant companions of man in order that their po- tential powers to act as vectors may be utilized. On this account it is stated that such insects as Simuliidae, Tabanidse, and sylvan mosquitoes may be eliminated, as they do not feed regularly on human blood, and are active during only a limited season, a condition that would necessitate too great an interval during which no transmission could occur. In addi- tion, it is stated that with insects which do not normally bite man, the chances of such species obtaining parasitic micro- organisms from an infected person and then inoculating a second person are too remote to allow for the perpetuation of the disease. These statements hold good for such diseases as yellow fever and malarial fevers so far as we know, since the pathogenic organisms are confined to man and specific mosquitoes in which they undergo a definite life-cycle. Two matters have been overlooked, however, which have a very important bearing on certain other insect-borne diseases. In the first place, there is the possibility that some human dis- eases may be common to animals. This has been demon- strated in the case of some infections, and in at least one in- sect-borne disease is known to occur. Thus, with African sleeping sickness, wild antelopes and domestic cattle may act as reservoirs for the trypanosomes that produce the disease and tsetse flies infected from them may spread the disease in man. That many more animal diseases may bear some such relation to man is probable, although present information relates mainly to infections (e. g., anthrax) which are not or- dinarily insect-borne. Secondly, the occurrence of chronic carriers must not be overlooked. Such conditions are best known in certain dis- eases such as typhoid fever and diptheria, where blood-suck- ing insects do not ordinarily spread the infection; but the piro- plasma of tick-borne splenetic fever (Texas fever) of cattle is known to persist in chronic cases. That such is commonly true of some human insect-borne diseases is by no means un- OF WASHINGTON, VOLUME XIV, 1912. 181 likely, and although it could hardly account for the persis- tence of a human disease carried exclusively by a specific in- sect vector, it renders possible the transfer of diseases by a contaminative carrier during certain short periods alternating with longer periods of inactivity. NOTE ON THE AVOCADO WEEVIL (HEILIPUS LAURI BOHEMAN). BY HERBERT S. BARBER. Bureau of Entomology, U. S. Dept. of Agriculture. Last month (March 1912) some aguacate seeds (avocado or alligator pear) were planted for germination in one of the green- houses of the Department of Agriculture in Washington, and while inspecting importations against noxious insects, Mr. E. R. Sasscer had his attention drawn to one of these seeds show- ing injury which, when the seed was opened, proved to be the result of a large weevil larva therein contained. Unfortu- nately the seed lay for a time on his desk subject to the at- tack of the ant-pest (Solc-nopsis dcbilis) from which the Bureau of Entomology suffers, before he brought it to me. When examined further the seed was found to contain, in addition to the half-devoured larva, two fine pupa3, each in a thin- walled cell of excrementous material, the three together al- most completely filling the space formerly occupied by the two great cotyledons. In the same greenhouse and at about the same time (March 19, 1912) an attendant had picked up and handed to Mr. Sasscer a large weevil that was feeding on the leaves and stem of a seedling aguacate and which had undoubtedly issued from another seed of the same lot. A few days later some one in passing through the greenhouse picked up another adult weevil for a friend interested in insects, who, in turn, brought it to me for determination. The species was described by Boheman in 1845 (Schonherr, Gen. et sp. Cure. vol. 8, pt. 2, p. 443) under the name Hcilipus luiui, stating that it was found in the fruit of Lauras dry- mifolia.* In the Biologia Centrali-Americana Champion mentions two specimens of this weevil from Capulalpam, Mexico, in 'Having been much confused by the different names assigned to the Aguacate and thinking several species might be involved, it may be well to explain that this name is now considered a synonym of what Small (-nils Perseapersea (L,)Ckll. and equals, asfarasIcanIearn,Zffwr7/j/te™?0 Linn.. Persea gratissima Gaertn.,and Persea americana Mill., but is a distinct species from the recently described Persea pit fieri Mez. 182 PROCEEDINGS ENTOMOLOGICAL SOCIETY the Salle collection. Two other specimens are in the U. S. National Museum collection, one of which was found on an aguacate at Ontario, California, November 22, 1911, by Mr. S. A. Pease, while the other wras found in an aguacate seed in St. Louis, Missouri, by Mr. Clay E. Jordan. Subsequent to the presentation of this note, further ob- servations were made which would best be added. On May 2, the greenhouse attendant found another adult in a spider web near a pot containing several avocado seeds and noticed an apparently fresh exit hole over one of them. I visited the greenhouse the following morning and tried to trace up all receipts of Persea seeds from which weevils might have issued. It seems only one lot was infested. This was received from a dealer in San Jose, Costa Rica, December 26, 1911, consisting of 26 seeds of Persea pittieri, which were then noted as being in poor condition. Five of these seeds had germinated and grown to plants from a foot to a foot and a half in height, and from the cotyledons of three of these plants weevils had issued, leaving a still very obvious exit hole in the soil close to the plant stem. These three plants were taken up and the cotyledons showed the same injury that had ap- peared from the other seeds, but, of course, this injury had not affected the germ. On May 23, four additional plants that had been grown at Miami, Florida, from seeds of the same lot were examined and the cotyledons showed no exit holes. A plant grown in the local greenhouse which when examined three weeks earlier had shown no sign of infestation, now had an apparently fresh exit hole in the soil about an inch from the stem, which led down into the pupal chamber in the coty- ledon. This plant seemed less robust in its growth than the others. Another adult, dismembered by ants, was found on a ledge in the greenhouse, but may have been there for weeks. A specimen of this weevil was taken early in July at Whit- tier, California, in a grove of avocados about 2 years old, in the nursery of Mr. Hideout. Mr. P. H. Dorset, of the Bureau of Plant Industry, who found the weevil, believes it came from Mexican seed, but states that no seed had been planted in that part of the nursery for nearly a year. Seven adults, two pupse, and a larva of this species are now in the National collection. Of the adults the four that issued in the Washington greenhouse from the seed of Persea pit- tieri from Costa Rica are of a decided red ground-color, with red femora, and lack the two transverse white fascia of the elytra, while the other three are dark brown, have unicolor- ous legs, and display the prominent patches of white scales mentioned and figured in the Biologia Centrali- Americana. PROC. ENT. SOC. WASH., VOL. XIV. NO. 3. THE AVOCADO WEEVIL (HEILIPUS LAURI BOH.). OF WASHINGTON, VOLUME XIV, 1912. 183 Coupled with the different host plant, these characters n ay later lead to the splitting up of this species. From these records it is quite obvious that the specirs rray become of some economic importance to tropical horticul- turalists and its transportation to other countries where the avocado is grown should be more closely guarded against. Further observations are urgently needed to determine the probable extent of its depredations. Plate ix represents a pinned adult and lateral and ventral views of the pupa. Mr. Schwarz said that the genus Heilipus, with its several hundred species, naturally will have quite a variety of food habits. One species, H. gnttatus Boh., wras bred by him last year from a section of a felled tree (probably a Ficu^) at Paraiso, Panama, and was also collected at wounds on tree trunks in Guatemala. H. albovenosns was found by him at Tampico, Mex. in December, 1910, on the fruit of Ncctandra sanguined? (as determined by Dr. Rose), which has been formerly include d in the genus Persea, with its probable larva within the fruit. An6ther species, H. e.legans, breeds under the bark of camphor trees in Jamaica, as he noted some years ago (Proc. Ent. Soc. Wash., vol. ix, 1909, p. 15). Only one species of the genus, H. squamosus, is native in the United States (Georgia and northern Florida). It is extremely rare in collections and its habits are still unknown, but it may be found to develop in the fruit of Persea borbonia (P.caroliuensis). A genus allied to Heilipns, Calvertius arancarice, has been described by Dr. D. Sharp (Ann. and Mag. Nat. Hist., Jan., 1891, p. 150) from Chile, where its Iarva3 bore in the trunks of Arancan'n imbri- cata. It may be added that three other small rhynchophorid beetles have been found to live in the seeds of the avocado. One of them is a calandrid beetle, Caulophilns lathiasits, Say, found in seed of the "Trapp" variety of avocado from Miami, Florida, in November, 1909. The second is a small unde- scribed scolytid of which a few specimens were found in the seed of an undescribed wild species of Persea, discovered by Dr. Henry Pittier at Boquete, 2,100 meters altitude, on the slopes of the Volcan de Chiriqui, in Panama, in April, 1911. The third is the cosmopolitan coffee weevil, Arcecerus fascicu- latus De G., which appeared in numbers in old seeds from Liv- ingston, Guatemala. 184 PROG. ENT. SOC. WASH., VOL. XIV, 1912.

XIV OCTOBER - DECEMBER, 1912. No. 4 MEETING OF APRIL 4, 1912. The 258th regular meeting of the Society was entertained by Mr. Marlatt in the Saengerbund Hall, 314 C Street NW. on the evening of April 4, 1912, and there were present Messrs. Banks, Barber, Caudell, Ely, Gahan, Howard, Knab, McAtee, Popenoe, Quaintance, Sasscer, Schwarz, Snyder, Stedman, Vickery, members, and Messrs. F. C. Craighead, J. R. Malloch, C. S. Minot, and W. B. Wood, visitors. President Quain- tance occupied the chair. The minutes of the preceding meeting and of the special meeting of March 14, 1912, were read and approved. Mr. W. B. Wood was elected active member. The first paper of the evening, "Description of an injurious Otiorhynchid," by F. H. Chittenden, was read by title.1 The second paper, "Notes on Blood-sucking and Supposedly Blood-sucking Leptidse," by Frederick Knab, was read by the Recording Secretary.2 Dr. Howard remarked that this added another family of Diptera to those to be considered in connection with insect- borne diseases. He inquired whether such diversities of habits within a genus is known among the families of Diptera gener- ally considered blood-suckers. Mr. Knab stated that this was the case in the Culicidse. In this group we get closely related species, some of which are 'Published, Proc. Ent, Soc. Wash., XIV, 106, 1912. 2 Published, Proc. Ent, Soc. Wash., xiv, 108, 1912. 185 186 PROCEEDINGS ENTOMOLOGICAL SOCIETY habitual blood-suckers and must have blood for the perpetua- tion of the species, others that are indifferent blood-suckers, and still others that do not attack warm-blooded animals at all. And this condition repeats itself in a number of genera, so that it is clear that the habit can not serve as a guide to the exact systematic position of the species. In the case of the Leptidse the habit perhaps appears so remarkable because we know so little of the habits of the group. Mr. Knab stated that he had been unable to find anything beyond the general statement that these flies are predaceous. He asked Mr. Malloch if he knew of any exact records by European entomo- logists. Mr. Malloch said that he only knew that the Leptidas are generally considered predaceous. The fact that Leptis rested upon tree trunks always with its head downward suggests that it watches for prey; its very sudden flight also suggests the predaceous habit. Mr. Schwarz said : As to Symphoromyia, he had observed it on the wing, evidently hunting for prey among the bushes, although he had never actually taken one with prey. Too much reliance should not be placed on the structure of the proboscis. Mr. Green, of Ceylon, had sent a muscid fly, Ochromyia jejuna Fab., to Professor Poulton with the state- ment that it had been found preying upon termites. This observation had been questioned on the ground that the mouth- parts of Ochromyia are unfit for piercing another insect. Although the flies were seen capturing the termites, Colonel Yerbury expressed his belief that the only possibility was that the termites had been injured in some way. Mr. Malloch stated that he had observed the female of an anthomyid fly, Spilog aster nigrinervis Zett., which was feed- ing upon another fly, Hilara litorea Fall. ; also a female and predaceous. In spite of the apparently inadequate structure of its proboscis the Spilogaster devoured the abdomen and all the softer parts of its victim, leaving only a small bundle of the chitinous parts. He had also seen Spilog aster preying upon small neuropteroid insects and upon Homoptera. Mr. Knab exhibited a number of species of the genus Atherix and expressed the opinion that they are not all con- OF WASHINGTON, VOLUME XIV, 1912. 187 generic. He showed Atherix ibis Fab., from Europe, and A. variegata Walk., from the northern part of our continent, and contrasted with them A. longipes Bell., and three other species, all from the warmer parts of America. The four tropical species agreed in their graceful form, longer and more slender legs and a number of evident characters. Mr. Knab said that he was unwilling to propose a generic name at this time, as a number of genera had been created agree- ing in general characters with Athemx and usually placed as synonyms of it. The status of these genera should be carefully established before creating a new one. Mr. Banks said that he was of the opinion that the southern forms are probably a new genus, since the European and Northwestern species of Atherix are locally common and if they are blood-suckers the habit would have been noticed long ago. The third paper, "A New Genus and Species of Gryllidie from Texas," by A. N. Caudell, was read by title. A NEW GENUS AND SPECIES OF GRYLLID^ FROM TEXAS. BY A. N. CAUDELL. TRIGONIDOMIMUS n. gen. Description (Female, the male unknown). — This genus belongs to the subfamily Gryllinse, but bears a strong superficial resemblance to Cyr- toxipha and related genera of small crickets of the subfamily Trigonidiinae. The second segment of the tarsi is minute, not at all depressed or cordi- form. Hind tibiae more slender than usual in the subfamily Gryllina? and armed above on the outer half with three spurs on each margin and on the basal part there are a few serrations, small but distinct when viewed through a hand lens. There are five apical calcaria, two ventral ones subequal in length and both short, scarcely as long as the tibial spines, and two longer ones on the inner side and one on the outer. On the inner side the middle calcar is about three times as long as the ventral one and the upper one a fourth longer than the middle. The second outer calcar is fully as long again as the ventral one. Metatarsus of hind tarsi rounded above, armed only with hairs, as are also the hind tibiae between the spurs and serrations. Fore tibiae furnished with foramina only on the anterior face. Head large and rounded, broader than the pronotum, the front convex; eyes very small and but little prominent. Antenna; inserted 188 PROCEEDINGS ENTOMOLOGICAL SOCIETY immediately beneath the eyes, distinctly nearer the clypeal suture than to the top of the head. Apical segment of the palpi moderately enlarged apically and triangular in shape as common in manygryllid genera. Ovi- positor approximately equaling the hind femora in length and almost straight . Type: Trigonidomimus belfragei, new species. Trigonidomimus belfragei, new species. Head large; eyes small, broadly oval, and set far apart. Pronotum nearly quadrate, narrower than the head or the width across the base of the elytra. Elytra shorter than the abdomen, about three times as long as the pronotum; wings caudate, extending half their length beyond the tip of the abdomen. Anal cerci very long. Legs moderately slender, hind femora moderately swollen and tapering to the very tip, the hind tibia; slender. General color brownish yellow, the tip of the ovipositor and the eyes and the base of the antenna blackish; the legs are clear honey yellow and the elytra are darker. The antenna? grow paler towards the tip. Length, antenna?, 15-)- mm.; pronotum, 1.25 mm.; elytra, 3.75 mm.; wings, 11 mm.; hind femora, 4.75 mm.; ovipositor, 4.5 mm.; anal cerci, 5.5 mm.; width, pronotum, 1.5 mm. Two females, Texas, Belfrage. Type: Coll. Museum of Comparative Zoology, Cambridge, Mass.; paratype, U. S. National Museum, Washington, D. C.(Cat. No. l"5389). The type bears the following written label : "59 Quite rare specimens, coming to light at night Sept. -Oct." At the conclusion of his paper, Mr. Caudell said he did not quite understand the significance of No ."59" which appeared on Belfrage's label. Mr. Schwarz explained that Mr. Belfrage had the habit of numbering those species of each order which he collected himself in Texas and to distribute them always under the same number among his numerous correspondents and customers in the United States and in Europe, so that should these num- bers be preserved it would add considerably to the identifi- cation of his specimens. Among the orthopterists in Europe he had a good customer in Professor Stal in Stockholm. Bel- frage collected only at two points in Bosque County, Texas, viz, Waco and Clifton, although in his letters he constantly speaks of proposed trips to other parts of the State. At the instance of Dr. Le Conte he commenced about the year 1875 to write up a list of the insects collected in Bosque County. OF WASHINGTON, VOLUME XIV. 1912. 189 As far as Mr. Schwarz recollects, only the list of the Coleop- tera was ever finished, and he has seen this manuscript in the possession of Dr. Le Conte in the year 1878. However, it has never been published and the manuscript is probably still in the possession of Mrs. Le Conte. A small fraction of a copy of this list of Coleoptera in the handwriting of Belfrage, including the Carabidse and Dytiscidse, is still in the possession of Mr. Schwarz. Belfrage wras not in the habit of labeling the specimens he sent to his correspondents; his peculiar and neat way of pinning and mounting render the specimens collected by him easily recognizable. Of the numerous let- ters Belfrage received from his correspondents from all over the world many are preserved in the National Museum. An obituary note on Mr. Belfrage will be found in the American Naturalist, 1883, p. 424. -The fourth paper was "Notes on Some Nearctic Mantis- pidse," by Nathan Banks.1 In connection with his remarks, Mr. Banks exhibited a new genus of Mantispidse from Australia which appears in three striking color varieties. He also showed specimens of a new thynnid wasp, and a new genus of Scoliidae from Arizona. —At the conclusion of the regular papers on the programme President Quaintance called on Dr. C. S. Minot, of Cambridge, Mass., who responded with a few remarks on the early New England entomologists and related some very amusing anec- dotes regarding Dr. Hagen. -Under Notes and Exhibition of Specimens Mr. Banks exhibited a bottle of insects taken from a freshly painted house and suggested that there was something in the color as well as the odor that attracted them to it. Mr. Barber stated as his opinion that the so-called attraction of painted surfaces is exaggerated. A more logical explana- tion in most cases would give greater importance to the tem- porary alighting and immediate continuance of flight in the seasonal swarmings of many insects caught on adhesive sur- faces. Different species behave differently; with some insects the odor of paint will be attractive and with others repulsive. 1 Published Proc. Ent. Soc. Wash., xiv, 178, 1912. 190 PROCEEDINGS ENTOMOLOGICAL SOCIETY Pine-infesting scolitids and other insects are probably attracted by the odor of paint, while other insects not instinctively as- sociated with turpentine odor are undoubtedly repelled. A common Pityophthorus was flying in great numbers along a woodland creek but did not appear to alight on his clothing. When, however, he stripped for a swim, he was greatly annoyed by their alighting and crawling, apparently due to the at- traction of the light color. Mr. Schwarz said that in his experience insects are not only attracted by light surfaces, but also by dark-colored ones if they are of sufficient size. He cited the north side of the old Department of Agriculture building, where in former years large numbers of specimens of various orders could always be found on each morning at the proper season. Mr. Knab stated as his opinion that the reason for the com- mon habit of many insects flying against white objects may perhaps be explained in that with their defective sight such objects are mistaken for open spaces — for example the open- ings among trees or other objects. Mr. Schwarz related that in the month of March of the pres- ent year, while on the island of Key West, Florida, he had the experience of being stung by the big black scorpion Centrums gracilis Latr., which is so common in tropical Florida. He was stung at the base of his right thumb and for some minutes the pain was most intense. No swelling followed, but the thumb as well as the whole hand was paralyzed for the rest of the day, the accident having happened about 11 o'clock in the morning. A dull pain extended from the hand nearly to the elbow, but did not prevent him from having good sleep. On the morning of the next day the pain had greatly lessened, but still he was hardly able to hold a pen for letter-writing, but there was no swelling of any extent and by evening the pain and paralyzed feeling had greatly subsided. On the third day hardly any effect of the sting was felt. No remedial measures whatever were applied. This scorpion feeds largely upon longicorn beetles, crickets, and roaches, which are so commonly found under bark of dead trees. In former years OF WASHINGTON, VOLUME XIV, 1912. 191 he had found at Miami a female of this species with 26 young on her back. Mr. Banks said that this species was one of our longest and was found from Florida to South America, in many places common. He referred to the poisonous scorpion of Durango, a species of Vejon's, of which Mr. Scrrwarz had received ad- ditional evidence of its poisonous qualities. Mr. Schwarz added that a few years ago he was in company with Mr. F. C. Bishopp at Durango City, where upon their first arrival they were treated by the inhabitants with many accounts of the deadly nature of the "alacron" ( Vejovis sp.). Hunting within the city produced only specimens of a common scorpion which is certainly not of a severely poisonous nature, and the accounts given by the natives were so contradictory that manifestly no reliance could be placed upon them. In- formation from more reliable sources elucidated the fact that the home of the real poisonous scorpion is the slope of the plateau towards the Pacific side, known as the Sierra de Du- rango, about 15 or 20 miles west of the city. This is a timbered country, whereas the city of Durango is situated on the bare plateau. It is from the Sierra de Durango that the specimens sent to Mr. Banks were collected. Mr. Schwarz added that while in Key West he met a most intelligent American who had resided for several years in the Sierra de Durango and who fully corroborated the former accounts of the severely poison- ous nature of the "alacron." In connection with scorpions, Mr. Schwarz said many people passing through Yuma, Arizona, have no doubt witnessed the performance of the Yuma Indians who come to the station at train-time, holding the big yellow scorpion, so common in that region, by the tail end and allowing the animal to crawl up their bare arms. The scorpions are offered for sale to the passengers, who usually pay liberally to be excused. Mr. Quaintance exhibited specimens of an interesting aley- rodid received from Dr. C. W. Hooker, collected by him in Porto Kico, December 15, 1911. This species had recently been described by Dr. G. Leonardi in Bollcttino del Labora- 192 PROCEEDINGS ENTOMOLOGICAL SOCIETY torio di Zoologia generale e agraria della R. Scuola superiore d'Agricoltura in Portici, vol. iv. The insect is remarkable by reason of the long curling wax threads secreted by the pupa, of which there are only two pairs. The species falls in a new genus, as set forth in a forthcoming paper on the classifi- cation of the Aleyrodidae by Messrs. Quaintance and Baker. MEETING OF MAY 2, 1912. The 259th regular meeting of the Society was entertained by the bachelors in the Saengerbund Hall, 314 C Street NW. on the evening of May 2, 1912, and there were present Messrs. Barber, Caudell, Ely, Heidemann, Knab, McAtee, Quaintance, Rohwer, Russell, Sasscer, Schwarz, Vickery, Viereck, and Walton, members, and Messrs. J. R. Malloch, William Mid- dleton, J. R. Strauss, and R. Wooldridge, visitors. President Quaintance occupied the chair. Mr. Rohwer read a letter from Mrs. J. B. Smith, expressing her deep appreciation for the action of the Society in calling a special meeting on March 14, 1912, for the purpose of draw- ing up resolutions in recognition of the work of the late Dr. John B. Smith. Mr. Schwarz brought up the question of a meeting in June and on a vote of the Society it was decided that such a meet- ing should take place. Mr. Rohwer suggested that the Society take some action in electing a representative at the meeting at Oxford this summer, and after some discussion the matter was laid on the table until the next meeting. At this juncture the question arose as to whether the Society should publish a biography of the late Dr. John B. Smith, and it was moved and seconded that Dr. Howard and Mr. Schwarz should draw up such a biography to be published by the Society. The first paper of the evening was by H. L. Viereck, on "Entomology at the Centenary of the Academy of Natural Sciences of Philadelphia." OF WASHINGTON, VOLUME XIV, 1912. 193 The second paper was by O. Heidemann, on "New North American Species of Tingitidse." Under "Notes on Nearctic Orthoptera" Mr. Caudell spoke of a catalogue of the Orthoptera of Nearctic America which he has in course of preparation. Following his comments he presented a paper by T. D. A. Cockerell on "A New Genus of Orthoptera from Guatemala." ENTOMOLOGY AT THE CENTENARY OF THE ACADEMY OF NATURAL SCIENCES OF PHILADELPHIA. BY HENRY LORENZ VIERECK. At the one hundredth anniversary of the Academy the whole field of the natural sciences was fittingly -epresented. If any one branch of science paid mon homage or received more recognition than another on this memorial occasion, then that honor belongs to entomology, for from the beginning until the end of the proceedings the great achievements of bhe Aca- demy and of entomology, from modest beginnings, were brought out in the addresses. Nineteen entomologists were appointed as delegates from at least seven distinctly entomological organizations and a number of more general institutions of learning. O the entomologist delegates Prof. P. P. Calvert, Prof. J. H. Corn- stock, Mr. E. T. Cresson, Prof. S. A. Forbes, Mr. Samuel Henshaw, Dr. W. J. Holland, Dr. L. O. Howard, Mr. C. W. Johnson, Dr. Henry Skinner, Mr. H. L. Viereck, and Prof. F. M. Webster were present at the celebration, which covered a period of three days or from March 19 to March 21. The entomological organizations represented were the American Entomological Society, the Association of Economic Entomologists, Societe Entomologique de France, the Ento- mological Society of America, the Entomological Society of London, the Entomological Society of Ontario, and the Ento- mological Society of Washington. The entomological papers read were by Dr. Henry Skinner on "Mimicry in Butterflies," and Mr. James A. G. Rehn on "The Orthopteran Inhabitants of the Sonoran Creosote Bush." The splendid entomological resources of the Academy were shown to the interested, who were also introduced to the m w entomological quarters just nearing completion. In the address of the president at he opening exercises such entomological pioneers as Thomas Say, Titian R. Peale, 'To be published later. 194 PROCEEDINGS ENTOMOLOGICAL SOCIETY Thomas B. Wilson, J. L. Le Conte, George H. Horn, Henry C. McCook, E. T. Cresson, and others were mentioned as the builders to whom we owe the entomological foundation laid down at the Academy. To quote, the president then said : "The knowledge gathered by the abstract naturalist and the tabulation of scientific data concerning all forms of animal and vegetable life have a very close and direct relation to public health and preventive medicine." Then he referred to such examples as yellow fever, malaria, sleeping sickness, and other diseases transmitted by insects, and pointed out what a boon it has been to humanity to know the minutest details of the life history of such creatures. To quote again, the president said: "The work of the Academy has been so distinctly pure science that the lay public have not until recently appreciated the great practical relationship it has to health and economics. The description of the various species, their life history, the geographical range, have enabled those working in applied sciences to conduct the already successful war against the enemies to man, to the lower animals, and to plant life. ' ' Then he went on to show what a great intrin- sic loss to our food supply and comfort was due to the depre- dations of insects, quoting the latest statistics to this end. Dr. Edward J. Nolan, the esteemed secretary of the Academy, under the title of "Reminiscences," gave interesting accounts the results of his opportunities to observe men of science, and mentioned Thomas Say as one of four men who had stood out prominently in the first century of the Academy. The meetings, the entertainments, and every feature of this memorable centenary of one of the foremost institutions of its kind in the world were so inspiring and genial that all who attended were happy to be present. RECOGNITION OF PALINDIA MERRICKI HOLLAND. This species was described from a specimen taken flying in low herbage near New Brighton, Pennsylvania. The de- scriber recognized that it was a stray from the tropics, but he could not locate it specifically. Recently in going over the Palindia in the National Museum collection, I found a series of this species under P. egista Bar. There were, however, two forms confused, and as Bar plainly indicates the other form as egista the name merricki will stand. Our specimens are from Venezuela. Probably the original specimen reached Pennsylvania as pupa with tropical fruit. HARRISON G. DYAR. OF WASHINGTON. VOLUME XIV, 1912. 195 A NEW GENUS OF ORTHOPTERA FROM GUATEMALA. BY T. D. A. COCKERELL, University of Colorado. Among the Orthoptera recently collected by my wife at Quirigua, Guatemala, is a large Ceuthophilus-Vke, species, which I could not place in any described genu? known to me or referred to in the literature at my command. Thinking that it might have been described in the Biologia Centrali Americana, I sent a brief account of it, with sketches, to Pro- fessor L. Bruner,who kindly writes me that he finds no such insect described, adding: "Undoubtedly your insect is new, and comes near Glaphyrosoma." MAYACRIS gen. nov. (STENOPELMATIN^E). Female. — A large insect, with the general form and color of Ceuthophilus, entirely apterous; feet with pulvilli; hind tibiae on upper side with two rows of short spines, all of the same type or grade. Head oblong, not wider than thorax; eyes elongate, twice as long as broad; ocelli represented by large oval chalky-white patches, one on the prominence between the antennae, the others on each side of the broad flattened frontal prominence; vertex not tuberculate; clypeus much narrowed below, the lower half strongly longitudinally sulcate in middle; labrum large, broad-oval not in the least emarginate, with scattered hairs; mandibles with strong apical teeth; third joint of labial palpi as long as the other two together; maxillary palpi with joints 2 to 4 greatly elongated, the fifth flattened and spoon-like; antennae more than twice as long as body; prothorax large, smooth, its lateral inferior margins nearly straight; anterior coxae with a strong but short spine; anterior tibia3 with a sulcus on each side, at the upper end of which is a rounded pallid foramen-like depression (wholly unlike the foramina of the Decticinae, however); femora wholly unarmed; anterior tibiae with two rows of five spines each on lower side, the last three of each row crowded toward the apex; there is also an apical spine on inner side; middle tibiae with the same ten interior spines, and also six superior ones, in two rows, the last of each row apical; hind tibiae with two rows of ten short spines above, none apical, no spines below except at apex; apex of hind tibiae with two very large spines (about as long as first joint of tarsus) on inner side and two not so large on outer, and in addition two pairs of spines beneath, the most apical pair larger and close together at base; first three tarsal joints strongly sulcate or excavated beneath, and variously produced at apex, but not in the least spinose; the tarsal joints are only moderately compressed; ovipositor very short, compressed, gently curved upwards. Mayacris bruneri, sp. nov. Female. — Body smooth and shining, about 26 mm. long, dark purplish brown above, very pale yellowish beneath; frontal prominence dark pur- 196 PROCEEDINGS ENTOMOLOGICAL SOCIETY plish, invaded from behind by two lobes of pale ochreous color; clypeus pallid with two suffused brownish patches; maxillary palpi about 15.5 mm. long; cerci about 5 mm.; ovipositor slightly over 4 mm. in length; anterior femora 9 mm., their tibiae 9.5; hind femora shining, pale purplish-brown, 22 mm. long, the greatest depth not quite 6 mm.; hind tibise 20 mm., dusky at base, pallid apically; hind tarsi a little over 7 mm.; third antennal joint longer than the next two combined. Habitat: Quirigua, in the tropical lowlands of Guatemala, February, 1912 (W. P. Cockerell). The generic name is derived from the Mayas, who in ancient times erected splendid temples and monuments at Quirigua. The species is dedicated to Professor Bruner, who has done so much to make us acquainted with the Orthoptera of Central America. Type: Unique female, Cat. 14799, U. S. National Museum This insect bears a superficial resemblance to certain mem- bers of the Rhaphidophorinse, but its structure shows it to bt long to the Stenopelmatinse. I take this opportunity to record a cew other Orthoptera collected by Mrs. Cockerell at Quirigua, and kindly determined by Mr. A. N. Caudell : Neolobophora ruficeps Burm., Homeo- gamia mexicana~Burm., Periplaneta australasice Fabr., Stag- momantis fraterna S. & Z., Harpagonyx maya S. & Z., Heteronemia incong-ruensftrunn., Am ilia wmrstvW// Bruner, Xiphidion mexicamim Sauss.,and Amphiaaisla azteca Sauss. Mr. Caudell said that except for a character not mentioned in Professor Cockerell's description, i. e., the absence of apical spines above on both margins of the hind tibise, he would be inclined to consider the above genus inseparable from Gla- phyrosoma. —Under Notes and Exhibition of Specimens, Mr. Caudell spoke of the great numbers of insects found on snowbanks in high altitudes. He mentioned particularly observations made in July on Pikes Peak, when hundreds of insects, mostly ones ascended from lower altitudes by flight or ascending currents of air, were seen on snow. He reasoned that these snow- fields caught the ill-seeing eyes of the insects, and attracted them, otherwise some few would most certainly have been found on the grass or stones in the vicinity. But only one small beetle, a native of high altitudes, wras found in any num- bers anywhere except on the snow-fields. —Mr. Caudell spoke briefly on the desirability of miscellane- ous observations being published. He pointed out that even OF WASHINGTON. VOLUME XIV, 1912. 197 the most fragmentary notes made and published by different observers on the habits and development of insects often accumulate into more or less complete life histories. Care should be taken to not duplicate published articles along these lines, but the republication of known facts is not necessarily to be decried, as such often serves as a check on the results as published by others. MEETING OF JUNE 6, 1912. The 260th regular meeting of the Society was entertained by the married members at the Saengerbund Hall, 314 C Street NW., on the evening of June 6, 1912, and there were present Messrs. Cory, Cushman, Ely, Gahan, Heidemann, Knab, Myers, Quaintance, Rohwer, Sasscer, Schwarz, Snyder, and Wood, members, and Messrs. F. C. Green, Fritz Johansen, and J. R. Malloch, visitors. President Quaintance occupied the chair. The minutes of the preceding meeting were read and ap- proved. The name of Reginald Wooldridge was proposed for active membership and in accordance with the rules laid over until the next meeting. Under unfinished business Mr. Rohwer brought up the question of a delegate to the Oxford meeting, and after some discussion it was moved and seconded that the matter be referred to the Executive Committee with power to act. Mr. Schwarz gave a brief report as a member of the com- mittee to draw up a biography of the late John B. Smith, and Mr. Rohwer moved that the committee be relieved. Seconded by Mr. Gahan, and carried. The first paper of the evening was "A New Tachinid from Porto Rico," by W. R. Walton, and in the absence of the author is was read by Mr. Rohwer. 198 PROCEEDINGS ENTOMOLOGICAL SOCIETY A NEW SPECIES OF TACHINID^ FROM PORTO RICO. (Plate X.) BY W. R. WALTON. The tachinid parasites on the adult beetles of the genus Lachnosterna so far as recorded seem to be confined to two genera, namely, Cryptomeigenia B. & B., and Eutrixa Coq. Although the above-named genera have been widely dissoci- ated in all the tables classifying the family, they are not dis- similar in general appearance, though varying in size, and may well be much more closely allied than has generally been acknowledged. But two species, belonging to each of the genera before mentioned, have hitherto been recorded as b ing parasitic on the adults of Lachnosterna, the habits of the remainder of the species included being as yet unknown to science. The hitherto known are Eutrixa exile Coq., and Cryptomeigenia theutis Walker, the host of which is mentioned below. One other North American species, namely, Mi- crophtalma disjuncta Wied., is known as a larval parasite of "May beetles." This was reared from a larval skin of Lach- nosterna arcuata by Mr. Theo. Pergande, October 5, 1891. Microphthalma occurs also in Europe, where it will probably be found to parasitize the larva of Melolontha. The genus Cryptomeigenia was. erected by Brauer and Bergenstamm1 in 1891 from a single male specimen col- lected in Brazil and which they called sett fades ; although Walker2 had previously described a species, namely, theutis, under the old genus Tachina; it was evidently overlooked by the authors of the genus. The late Mr. D. W. Coquillett was, it seems, the first person to n cognize this species as being :ongeneric with seti fades B. & B., and we find it referred to its proper place in his indispensable "Revision of the North American Tachinidse." Brauer and Bergenstamm's descrip- tion of Cryptomeigenia setifacies is in a large degree unsatis- factory because of its lack of specific detail, but since it disagrees in some important particulars with several specimens in hand, and as it is impossible for the author to see the type, a new species is herewith proposed for their reception, which is called aurifacies. This is obviously distinct from theutis of Walker, which is known as a parasite of Lachnosterna in the northern United States, having been reared from an adult of Lachnosterna inversa Horn, by Mr. Theodore Pergande, at Washington, D. C., in 1892. 'Zweiflug. des Kaiser. Mus., v, 331, 1891. 2List, iv, 228. PROC. ENT. SOC. WA8M., VOL. XIV. NO. 4. A NEW SPECIES OF TACHINIDAE. OF WASHINGTON.

Described from six specimens, male and female, reared from the "sugar cane May-beetle"' by D. L. Van. Dine, collected April 29, 1912 at Anasco, Porto Rico. Type: Deposited in U. S. National Museum, Washington, B.C. Under Notes and Exhibition of Specimens Mr. Rohwer men- tioned having bred the fly DasyUis thoracica from the gal- leries of a scarabseid beetle in chestnut. This may establish a parasitism for this fly, which collectors have often found flying around old stumps infested by beetle larvse. In answering Professor Quaintance's query in regard to the important parasites of Lachnosterna larvse, Mr. Rohwer stated that the people in Porto Rico were working more with the hymenopterous parasites than they were with the dipterous. They have bred one species belonging to Cainpsomeris and are trying to introduce a species of Tiphia from the middle United States with the hope that this species will work -effect- ively as a parasite to the Lachnosterna larvse in Porto Rico. Professor Froggatt, of Australia, has bred a species of Scolia from the larvse of white grubs in Australia and has carefully described and figured these parasites of white-grub larvse. Mr. Rohwer stated that he was of the opinion that the people of Porto Rico could do better if they worked more extensively on the species belonging to family Scoliidse and did not endeavor to introduce North American Tiphia, as it is doubt- ful if the species Tiphia will acclimatize themselves to Porto Rico. He also stated that most of the North American species of Tiphia which live in the eastern United States have been con- sidered to be Tiphia inornata, but that there are really many forms which belong to this specific group and that the species of the Middle West, in the main, are different from the species of the Atlantic Coast. Judging from the diverse species it is impractical to endeavor to introduce Tiphia inornata into Porto Rico. As most of the species which belong to this group 1 Mr. E. A. Schwarz says that this is in all probability Lachnosterna crenatocollis Blanchard. OF WASHINGTON, VOLUME XIV, 1912. 201 of families in Porto Rico are of the family Scoliidae, it would be much better to endeavor to work with these rather than with the species of the family Tiphiidse. —Under a discussion of geographical distribution Mr. Knab remarked that Diptera as a whole are not as widely distributed as is generally supposed, but when carefully studied are found in most cases to be equally restricted in habitat with other insects not so well equipped for locomotion. Most of the species that show an exceptionally wide distribution are such as are favored by human activities. Aside from these the supposed wide distribution is based largely on inexact identification, similar species in different areas being confused. It will, accordingly, be found that the more obscure species, and the groups least understood, show the widest distribution. Another factor to be guarded against is errors in labeling. These are particularly to be guarded against in the collec- tions of the older entomologists, who cared little for exact data of this kind and often did not affix locality labels to their specimens. Thus the labels on some of the older material in the National Museum collection are obviously wrong and in some cases have gone on record. Some striking cases have turned up among the material from the collection of the late Mr. Coquillett. His collection consisted largely of material collected by himself in northern Illinois and around Los Angeles, California. The collection came to the Museum un- labeled and was afterwards labeled by an assistant. It was inevitable that errors should occur. A striking case is Psoro- phorn cilititu, which was recorded by Dr. Dyar from Los Angeles on the strength of a specimen from the Coquillett collection. The species has not been found in California by anyone else, nor at points farther west than Texas, and Mr. Knab said that he was convinced that the species does not occur in California. Mr. Knab said that he believed that we have another case of this kind in Simnliinu bracteahnn Coquil- lett, the types of which are labeled "Cambridge, Mass." and "Los Angeles Co., Cal." Specimens from other eastern locali- ties have since been turned up, but none from California, and the latter record is to be looked upon with suspicion. 202 PROCEEDINGS ENTOMOLOGICAL SOCIETY Mr. Malloch said : There are certain causes which limit the geographical distribution of an insect, and one of the principal factors in the limitation of phytophagus species is the range of the food plant. Although the species may not necessarily occur everywhere its food plant does, it does not occur where the plant does not, unless in certain cases where there may be closely allied plants upon which it may feed. This principally applies to Trypetidse. In the case of species feeding on car- rion or decaying vegetation the distribution is not governed by the occurrence of their food, but by climatic and other factors. Of the 29 British species of Faiinia, an anthomyid genus of habits last referred to, he took 23 species within a radius of 5 miles in Scotland, and of these 16 occur in North America, which is a much larger proportion than is the rule in other groups, and particularly in the phytophagus genera. MEETING OF OCTOBER 3, 1912. The 261st regular meeting of the Entomological Society of Washington was entertained by Mr. Schwarz at the Saen- gerbund Hall, 314 C Street NW.,on the evening of October 3. Present, Messrs. Barber, Busck, Caudell, Corey, Cushman, Dyar, Gahan, Gill, Heidemann, Hopkins, Myers, Popenoe, Quaintance, Rohwer, Schwarz, Stedman, Symons, and Walton, members, and Messrs. J. D. Hood, W. Middleton, J. B. Parker, and R. C. Shannon, visitors. President Quaintance occupied the chair, and in the ab- sence of Mr. Sasscer, Mr. Busck was asked to act as Record- ing Secretary pro tern. The minutes of the preceding meeting were read and ap- proved. Mr. Caudell proposed the name of Mr. J. D. Hood, Mr. Rohwer the names of Messrs. F. Johansen and W. Middleton, Dr. Hopkins the name of Mr. C. T. Green, and Mr. Busck the name of Mr. Carl Heinrich, for active membership. These names were laid over according to the rules. The President informed the Society that Mr. R. Wooldridge, whose name had been proposed at the last meeting, had asked OP WASHINGTON. VOLUME XIV. 1912. 203 to have his name withdrawn on account of his unexpected removal from Washington, and in view of this his name was not voted on. The first paper, "Notes on Nearctic Orthoptera. I. Non- saltatorial Forms," was read by the author, Mr. A. N. Caudell.1 Discussing Mr. Caudell's paper, Mr. Schwarz asked how the number of species of Phasmidse in arid regions compares with the species from the more humid regions. Mr. Caudell replied that it was his impression that the species recorded from arid regions are somewhat less than those from more humid areas. Professor Quaintance asked how many cave species occur in the Orthoptera. Mr. Caudell answered that aside from the species of the genus Hadenoecns, which are mostly confined to caves, there are few of our species peculiar to caves. Professor Symons asked what the distribution of Diaphe- romera femora fa is. Mr. Caudell stated that it occurs all over the north and south into Texas, where it is replaced by D. z'elli, which, however, ranges north as far as New York. Mr. Busck remarked that he was glad to note that Mr. Cau- dell had united genera and subgenera, which differed only in secondary sexual characters, and the generic value of such characters was discussed at some length. Mr. Caudell said that it is his opinion that genera based only on secondary sexual characters should not stand, but so far he has not carried this out radically. Mr. Schwarz remarked that in Coleoptera the secondary characters situated in close proximity to the primary sexual characters have been and still are successfully used as generic characters; the more remotely they are situated from the primary sexual characters, the more they lose their value as generic characters, without, however, losing their value as one of our best means of distinguishing species. Mr. Barber asked Mr. Busck what constitutes a secondary sexual character, to which Mr. Busck responded that he con- JTo be published in the Proceedings of the United States National Museum. 204 PROCEEDINGS ENTOMOLOGICAL SOCIETY siders any difference between the sexes outside of the primary sexual characters to be such. Mr. Barber then asked what one was to do in such groups as the Strepsiptera and the coleopterous group Phengodini, in which there is not a single structure common to the opposite sexes. Dr. Hopkins interpreted secondary sexual characters as those external characters which are peculiar to either sex and finds that the combination of these characters on both sexes of the same species serve as good generic characters. Mr. Knab said that in the Diptera he considered the em- ployment of secondary sexual characters objectionable. These are often misleading; as similar modifications may rise in- dependently at different points they can not be relied upon as indications of relationship. Mr. Walton said that in the Tachinidse the late Mr. Co- quillett quite successfully and wisely avoided the use of secondary sexual characters in the delineation of his genera. On the other hand, Mr. C. H. T. Townsend has made very general use of these characters in erecting genera, even when the genotype happened to be a unique. The genus Ennyomma Townsend was erected on a unique male solely because of the fact that this specimen possessed hairy eyes. This genus was split off from Myiofihasia B. & B. In a series of 24 speci- mens of Mytophasia cenea Wied. reared as parasites of Chal- codermus ceneus Boh. by G. G. Ainslie, of the United States Bureau of Entomology, at Clemson College, South Carolina, the males have hairy eyes and the eyes of the female are bare. The amount of pilosity of the male eye varies from a few scattered hairs to the densely hairy form. Notwithstanding this, Mr. Townsend persists in declaring that "the genus may be distinguished from both Myiophasia and Phasioclista by its thickly hairy eyes." From the above-mentioned facts, however, it will be seen that this hairiness is extremely variable, and at best is a secondary sexual character, and as such, in Mr. Walton's opinion, should not be used as a primary char- acter for the erection of a genus in Tachinidse. Dr. Gill remarked that supplementary sexual characters developed independently of the real sex organs are used to a OF WASHINGTON, VOLUME XIV, 1912. 205 large extent in mammals and in birds; they are sometimes developed in a remarkable manner, as in the birds of paradise, of which some 20 or 30 species in nearly as many genera are distinguished and recognized by all ornithologists entirely on these accessory characters, such as peculiar feathers on the forehead, tail, or elsewhere, found in the male, while the female is quite ordinary. Dr. Gill said that if such a male were divested of its feathers it could not be recognized generically. -Dr. Hopkins spoke of a minute scolytid beetle from the Philippines, in which the tibia of the male is very broad and carries very long, branched, featherlike hairs and a long spine, neither of which is found in the female. -Dr. Dyar showed a copy of "Moths of the Limberlost," by Gene Stratton Porter (pub., Doubleday, Page & Co., 1912). This is a book intended for "nature lovers," not for students or even beginners. It gives a general account of the appear- ance and habits of some of our larger moths and of the doings of the author and members of her family in relation to these moths, all very entertainingly told. The author herself has apparently been very unfortunate in her use of books. Harris's "Insects Injurious to Vegetation," which would probably have been her best guide, she seems never to have heard of. She searched in vain through Holland's "Moth Book" and Packard's "Guide to the Study of Insects" for details of the life histories of two species of Catocala that came under her notice. The authors of these works, as well as other entomolo- gists, receive scant courtesy at her hands, which seems scarcely edifying and somewhat detracts from the tone of the book. The two species of Catocala referred to above, C. amatri.v Hubn. and C. neogama S. & A., are well-known inhabitants of the cottonwood and hickory, respectively, overwintering in the egg state in crevices of the bark after the manner of other species of the genus. Is it a fact that these well-known details of the histories of our moths are so buried in the literature that one comparatively unacquainted therewith can not find them out? We scarcely think so, but attribute the failure to the author's ill fortune in selection of literature and advisors. In another place (p. 343) the author expresses the 206 PROCEEDINGS ENTOMOLOGICAL SOCIETY opinion that Citheronia regalis is "beyond all question" of tropical origin. This is true, of course, of the genus, but the author is speaking of the species, which is confined to the United States east of the Plains, as is well known. Some little space is devoted to a discussion of the ground color of the fore wing of this species. It appears that Dr. Packard described it as olive green, whereas Mrs. Porter insists that it is gray, and she wonders who is color-blind. As a matter of fact, the lady is right — it is gray; but the optical effect of the contrast of the red veins on the neutral gray ground gives the effect of the complementary color, green, so that the general im- pression is of an olive-gray wing. This is the impression I had carried of the species myself, and in a way justifies Dr. Packard's description. Many interesting photographs from life are found in the book and several colored plates, repro- duced from paintings by the author, in which she has tried to represent exactly the colors at their best, sometimes some- what to the detriment of the markings. -Dr. Dyar also showed a copy of "Elementary Entomology" by E. D. Sanderson and C. F. Jackson (pub. Ginn & Co.). -Mr. Caudell stated that Senor Federico Mejia, minister from Salvador, brought to his office yesterday for identifi- cation and information an adult pair of a locust which threat- ens to become, if indeed it is not already, a most serious pest to the coffee bean. Some weeks ago immature specimens were sent in, but the species could not be determined, though it was clear that it belonged to the genus Cocconotusi a genus of the subfamily Pseudophyllinee. Mr. Caudell had not yet had an opportunity to determine the species, but the adults which he had for exhibition are very surely the same as some brought from Salvador some years ago by Mr. Knab, who stated that they were injurious to the coffee bean and- leaf, according to the reports of the natives. Senor Mejia stated that these insects occur in immense numbers and cause thousands of dollars' damage. A single nip means the ruin of a coffee bean, as the place bitten turns black and makes the berry unsalable. The insect stays in the trees day and night and the remedies tried so far were the gathering by hand by OF WASHINGTON, VOLUME XIV, 1912. 207 children at so much per pound and the use of turkeys, which ate the insects when shaken from the trees or such as were within their reach on the lower limbs. Some years ago he had all the banana and other trees and shrubbery cut from the coffee fields, hoping that would serve to discourage the pest. Little result seems to have followed. He nowr asks very ear- nestly what he shall do. Knowing little of the life or habits of the insect and nothing of the effect of arsenical or other sprays on the coffee tree, Mr. Caudell did not know what to advise. Mr. Quaintance suggested that arsenical treatment might be used and Mr. Knab thought sweetened poisoned bait might be of value. Mr. Schwarz stated that according to Senor Mejia, these Orthoptera appear at the beginning of the rainy season as unwinged specimens and acquire their wings shortly after. It appeared to Mr. Schwarz that oviposition probably is made in the twigs of a tree, as the eggs from dissected females would seem too long to be laid in the stems of weeds; this ought to be ascertained, as it has an important bearing on eventual remedial measures, whether the young specimens are found on weeds or on tall trees used universally in these re- gions as shade for the coffee trees. -Mr. Walton said : I wish to announce on behalf of Mr. E. O. G. Kelly, of the Bureau of Entomology, who is now stationed at Wellington, Kansas, that he has apparently settled definitely the old argument as to whether the American members of the genus Sarcophaga are truly parasitic or not. During the past summer there has been a severe outbreak of Melanoplus differ entialissfoA Mclanoplusbivittatus'vn. Kansas, wrhich Mr. Kelly has been studying. In the course of his observations he noticed that when the grasshoppers flew through the air certain flies apparently followed them and darted down at them while on the wing. Upon capturing some of the grasshoppers he discovered tiny maggots attached to the abdomen, watched them enter the grasshopper through the tender spaces between segments, and reared the adult flies from them. I have examined the series of adults sent me for determination, and have been able to 208 PROCEEDINGS ENTOMOLOGICAL SOCIETY determine one specimen as a male of Sarcophaga hunten Hough. This species happens to be structurally distinct, and, therefore, quite easily determinable. There are, however, at least three species involved in the problem, and in all probability more than three. Mr. Knab said that the Sarcophagidse illustrate very well how backward we are in America in some branches of Dip- terology. In Europe it has long been known that certain species of Sarcophagidse are parasitic on other insects; the' facts having been established beyond all question, by compe- tent observers. Kunkel d'Herculais, in his studies on in- jurious locusts (Stauronotus maroccanus) in Algeria, made useful investigations and found that certain species of Sarco- phagidse are important parasites of the locusts. The females of these forms have a modified ovipositor and pierce the host to introduce their larva?, just as is the case with certain Tachi- nidae. Lahille, in the Argentine Republic, has shown that certain Sarcophagidge are parasitic there. Villeneuve has es- tablished genera on certain parasitic species. In this country Chittenden has bred a sarcophagid from a live beetle. A scarophagid has also been bred repeatedly in this country from the box-turtle, and this observation has been made so often that the insect involved must be looked upon as a true parasite of the turtle. —Mr. Caudell presented the followingnotes on Orchelimum pulchellum : On October 2, 1912, at Rosslyn, Virginia, I found near the river a bunch of Hibiscus militaris Can., which has very soft wood with a corky pith. The stems were literally filled with the eggs of what I am quite sure is1 the above species, as many of both sexes were found on the bush, though none of the females were found in the act of egg-laying; the time of ovi- position, however, was not past, as I found the females still with eggs. It may have been another species that laid the eggs, but it was more likely the above species. Eggs taken from the abdomen of captured females were very like those taken from the stems. It seems, so far as I can make out from the eggs as placed in the stems studied, that from two to OF WASHINGTON. VOLUME XIV. 1912. 209 a dozen eggs are laid in one puncture. The insect appears to sit facing up the stem and when but two or three eggs are laid in one puncture the ovipositor is directed only down the stem, but when several eggs are deposited some are directed towards the base of the stem and some towards the tip, showing that the ovipositor is directed towards the base of the stem part of the time and then towards the tip. I do not know whether the insect withdraws the ovipositor in changing the direction of the puncture. The eggs are usually placed in the wood; very close under the bark in the larger stems, as shown by the specimens ex- hibited, but in the smaller stems they are sometimes deposited in the soft inner pith. Green stems seem preferable for pur- poses of oviposition, but fresh eggs are also found in dead stems. -Upon request from the chair Professor Parker spoke of his experience with Cuterebra in rabbits; he had shot a half- grown rabbit in August in Knox County, Ohio, which had three infestations, one larva already dropped out, another dropped out when he lifted the rabbit up from the ground, and one larva had to be pressed out. In 1907 he had likewise seen full-grown larvae in a rabbit not -more than 2 or 3 months old, which would prove a rapid larval growth of this species, the adult of which appeared in June. Mr. Knab mentioned that the mature larva are frequently received from hunters in the fall. This spring he succeeded in breeding an adult from a larva received last fall. May and June is the normal time of appearance of the fly. Mr. Walton said he had bred Cuterebra cuniculi in Harris- burg, Pa., the fly appearing in June. Mr. Caudell asked whether the larvae occurring in rats were of the same species. Mr. Knab answered that he has not seen larvae of this species and that he was not aware that it had been bred, but as Cuterebra seems to be restricted to rodents it is probable that the larvae in rats are also Cuterebra. Probably different species of Cuterebra infest different ro- dents indifferently. One species, C. emasculator, has been described from the genitalia of a male squirrel ; but he did not think that species was peculiar to the squirrel. Mr. Walton 210 PROCEEDINGS ENTOMOLOGICAL SOCIETY thought that the C. emasculator would prove an exclusive parasite of squirrels and that this is indicated by its smaller size. —Mr. Barber exhibited specimens of the eggs of Cicada lyricen and presented the following notes for publication : EGGS OF CICADA LYRICEN DEGEER. BY HERBERT S. BARBER. The egg-laying habits of the periodical cicada are so well known to everyone that we are too apt to consider its injury as typical of the cicadas. Newell (U. S. Dept. Agr., Bur. Ent. Bull. 60. pp. 52-58) has, however, described the oviposition of a second species, Cicada erratica Osb., in the South, but be- yond this it seems that nothing on the subject is known of our more common species. The reference by Smith and Grossbeck (Ent. News, April, 1907, p. 118) to DeGeer's "egg-laying habit of the adult" of his Cicada lyricen seems un- fortunate in that the eggs he mentions must belong to some other insect. From DeGeer's ac- count (Mem. Hist. d. Insects, vol. 3, 1773, p. 215) one finds that his specimens consisted of adults and pupal r-kins sent him by M. le Prevots Acrelius from Pennsylvania and Ni'w Jersey, with some remarks on the song and egg-laying habit. The ref- erence to the latter, freely trans- lated, is as follows: ". the females place their eggs in the forks of the branches and these eggs, which are like white points, are confined in a sort of , r,. , , . hard and transparent gum-like FIG. 2.

A female of one of the common cicadas collected at random on Plummers Island, Maryland, was placed in a jar with a hard, dry hickory twig of about one-half inch diameter standing \) OF WASHINGTON, VOLUME XIV, 1912. 211 upright in the sand. A few days later she was found dead, and on close examination two or three very slight indications of punctures were found in the smooth, hard bark. Many clusters of eggs wen found by cutting into the bark, but in very few cases could the puncture be detected before the eggs were exposed. These punctures appear to have been closed with a mucilaginous secretion which allows the disturbed and broken fibers of the bark to swell back into their original position before drying, when they are firmly cemented to- gether. In some instances a thin membrane like dried albumen covers the open spaces between the fibers. The incision is a cylindrical cavity 8 mm. long and less than a millimeter wide, paralh 1 to the surface and usually in the inner bark, but often partly in the wood. One incision was found in which the eggs were within the wood itself. The eggs are laid alternately in a double row and usually number 12 or 13. The eggs measure 2.1 to 2.2 mm. in length by 0.35 mm. in width, are subcylindrical, slightly curved; one end tapers more gradually and is nure evenly rounded, the other is more bluntly conical. . The identity of the female is somewhat doubtful, but ap- pears from comparison with specimens in the National Mu- seum, and reference to Smith and Grossbeck's paper, to be Cicada lyricen DeGeer. ' Dr. Hopkins thought these eggs wrere truly those of the cicada and complimented Mr. Barber on their discovery. —Mr. Quaintance called attention to injury to walnut leaves and shoots by the walnut curculio, Conotrachelus juglandis, and exhibited photographs of the injury. Specimens of in- jured leaves and shoots have been received the present season from Titus ville, Pennsylvania, Upper Marlboro, Maryland, and Stamford, Connecticut. Dr. R. T. Morris, writing of the injury at Stamford, Connecticut, states: Ordinarly in the vicinity of my country place at Stamford, Conn., this species has confined itself, so far as I know, to the involucre of J. cinerea; at least I have never noticed it except there before. When I introduced large numbers of exotic walnut trees this beetle changed its habits, finding a suitable place for depositing its eggs in the rapidly growing herbaceous shoots of the species of .Juglandarea1 mentioned (Jnglans regia, J. siboldii,}. cordifonnis,J. cinerea, and Hicoria minima). It has practi- cally wiped out one orchard of/, regia for me and tlm-atms I he industry 'This determination has very kindly been confirmed by Mr. W. T. Davis. 212 PROCEEDINGS ENTOMOLOGICAL SOCIETY so seriously that we probably shall have to give up raising /. regia in the East unless some means for control can be found. The larvae infest the swollen base of the leaf-stalk and also hollow out the tender shoots. As stated by Dr. Morris, the eggs are deposited in the shoots of various walnut trees from the first week in May until September, and he has noted beetles on the trees as late as October 5. -Mr. Quaintance exhibited specimens of a chrysomelid beetle, the grubs of which had been complained of as quite injurious to cranberries in one locality in New Jersey. The insect was determined by Mr. Schwarz to be Rhabdopterus picipes Oliv. The species has not heretofore been reported as of economic importance, and, in fact, but little is known as to its habits. The larvae were present in a cranberry bog in the neighbor- hood of New Egypt, New Jersey, and had destroyed the plants in small patches here and there over the bog. The injury consists in the destruction of the fibrous roots of the cranberry plant and the eating off of the bark of the larger roots. The injury is very similar to that done by the grape root worm, Fidia viticida, to roots of the grape. Observations made in the cranberry marsh indicate that the beetles feed, to a certain extent at least, on the tender foliage of the cranberry plant, and it is thought possible that advantage might be taken of this fact to secure their destruc- tion by the timely use of arsenical sprays. Beetles confined with cranberry plants in rearing cages in the insectary at Washington fed freely upon the foliage, but spent a good deal of time below the surface of the soil, where they probably oviposit, as eggs were found in the soil. -Mr. Schwarz remarked that of the multitude of eumolpid Chrysomelidse which inhabit America hardly anything is known of their natural history or of their range of variation. Even in North America there are genera of which we know very little, for instance the genus Typophorus, which includes the strawberry leaf -beetle (now known under the name of 7. canellus Fabr.). At present all our eastern spotted or black forms are listed as varieties of one species, whereas it is almost OF WASHINGTON, VOLUME XIV. 1912. 213 certain that we have several good species among them. At any rate, the form described by Say as Colaspis sexsignata, which is very abundant on juniper (as already stated), never occurring on any other plant and never exhibiting any note- worthy color variations, is certainly a good species. How many species we have among the other forms must be settled by future observations. The following papers were accepted for publication : NEW SPECIES OF NOCTUID^ FROM THE GUIANAS. BY W. SCHAUS.

Brues discusses remarks by the writer, made at the meeting of January 4, 1912, and published in our June issue (pp. 79-81), on the association with man of those blood- sucking insects that have proved to be disease-transmitters. It was not my intention to review the entire field of insect transmission of disease, but simply to point out that in the case of insect-borne blood-diseases such association does exist. I aimed to make it clear that my remarks were restricted to diseases caused by parasites requiring alternate hosts. Being aware of the contradictory or seemingly contradictory facts, and appreciating that my remarks were open to some of the 220 PROCEEDINGS ENTOMOLOGICAL SOCIETY objections raised by Dr. Brues, I wrote a more extended discussion of the subject and touched (too lightly, it now appears) upon the contradictions. This paper appeared in a well-known entomological periodical1 nearly two months in advance of the discussion criticized and should have come to Dr. Brues's notice. I find it necessary to reply to Dr. Brues's criticism, as he has somewhat confused the subject by intro- ducing the mechanical conveyance of other classes of disease into the discussion. Such diseases very obviously do not depend upon such close association of particular insects and may be acquired in a variety of ways. In the case of true blood-parasites the association is necessary, not only that, as Dr. Brues puts it, transmission may take place, but in order that the host-relation may become established. I am fully aware that it has been experimentally proved that cer- tain blood-diseases can be transmitted mechanically by blood- sucking insects which are not hosts of the disease-producing parasite. In these experiments positive results were only obtained when the partly fed insect was at once transferred to a healthy animal and the bite followed immediately. This combination of circumstances must occur very rarely, if at all, in nature. Even should it occur, the transfer of the para- site will not be, by any means, always effected. In a practical consideration of blood-disease transmission it is certainly a negligable factor. The case of the African sleeping-sickness requires some explanation, as it is in a different category from those dis- eases caused by true blood-parasites of man. Here we have to do with a disease caused by hamatozoans not normally parasites of man. These protozoans are normally the para- sites of the wild animals which abound in those parts of Africa; they do not seriously affect their normal hosts, but they be- come highly pathogenic when introduced into the human circulation. That this is the true condition with sleeping- sickness is now generally recognized. In this respect, then, the parasites of sleeping-sickness differ from most other blood- parasites, that they may become established in a vertebrate host other than their normal one. In the case of most other blood-parasites, as those of malaria, yellow fever, pappataci fever, and filariasis, it has been determined beyond question that they can thrive only in a single vertebrate host. But with trypanosomiasis, as with the diseases just mentioned, the continuance of the disease depends upon the association 'Unconsidered factors in disease transmission by blood-sucking insects. Journ. Econ. Ent. vol. 5, pp. 196-200 (April, 1912). OF WASHINGTON, VOLUME XIV. 1912. 221 of the two hosts, in this case the tse-tse flies and the verte- brates, and a sufficient abundance of both. That the associa- tion between the hosts of trypanosomiasis is not a close one is compensated for by the long period during which the para- sites are present in the circulation of the vetebrate host and by the great abundance of these hosts. Furthermore, there is reason to believe that when the habits of the different species of Glossina have been carefully studied, specialization of habits along the lines indicated will be found to exist in the species concerned in disease transmission. A SYNONYMIC NOTE ON THE MYMARID^. BY A. A. GIRAULT. Parvulinus Mercet equals Alaptus Haliday. In the Boletin de la Real Sociedad espailola de Historia Natural, Madrid, June, 1912, pp. 332-335, figs. 1-3, Ricardo Garcia Mercet describes the genus Parvulinus as new to the family Mymaridse for the species P. auranti Mercet. Unfortunately, the author has been mistaken, for a perusal of the description shows that Alaptus Haliday has been re- described. The species auranti is thus an Alaptus, and knowing the wide distribution of members of this genus it would not be surprising if it should turn out to be one of the common Eu- ropean species of that genus, for instance, minimus of Walker. Thus, the species must be considered at best but doubtfully valid. The figures given of the antenna and wrings certainly resemble those appendages in what I have identified as the species minimus. Mercet also probably falls into error concerning the host of his Alaptus, since the members of this genus are usually parasitic upon psocid eggs, while Mercet states them to be parasitic upon coccids, merely from the fact that, if I have rightly understood, they \vere reared from twigs infested by coccids. Now, psocid eggs often occur among colonies of coccids. In this connection I must again state that the genera of the Mymaridae are few. A SYNONYMIC NOTE ON THE TRICHOGRAMMATID^E. 4 BY A. A. GIRAULT. Jassidophthora Perkins equals Brachistella Girault. R. C. L. Perkins, in Bulletin No. 10, Entomological Series, Experiment Station of the Hawaiian Sugar Planters' Asso- 222 PROCEEDINGS ENTOMOLOGICAL SOCIETY elation, Honolulu, 1912, on pages 17 to 19, describes the genus Jassidophthora for J. prima as new to the family Tricho- grammatidse of the Hymenoptera Chalcidoidea. As I have just completed a paper on the Australian forms of the family, describing a number of new genera, and also because I have in course of publication a new description of the genera of the family, it became necessary to examine at once the status of this new genus of Perkins. Unfortunately, it appears to be the same as my Brachistella described in 1911. As I will have fully explained elsewhere, the genera Brachistella and Abbella are much alike, closely related, differing only in the density of the discal ciliation of the fore wing, and Jassidophthora agrees very well with the description of the former. I am more anxious to come at the truth concerning thi," new genus, since I have been at fault in the original descrip- tions of both of my own genera, there being two ring-joints, instead of but the one, in the antenna? of both. This is also true of Ittys Girault. Full details are given elsewhere. The first funicle joint in Jassidophthora is doubtless a second ring-joint and the antennae thus agree with those of Brachis- tella. It thus seems necessary to designate Jassidophthora prima Perkins, Brachistella prima (Perkins), a species which appears to be valid. Perkins has, I think, been misled in thi case by my own errors.
