JANUARY-MARCH, 1917 Nos. 1-3 TWO BETHYLID PARASITES OF THE PINK BOLL WORM {Hymenoptera, Bethyliida:) By S. a. ROHWER In this paper, which is a contribution from the Branch of Forest Insects, Bureau of Entomology, two Bethylid parasites of the pink boll worm are discussed. One of them, which has heretofore been considered as Parasierola celMaris (Say), is described as new. Perisierola nigrifemur (Ashmead). Goniozus nigrifemur Ashmead, Journ. Linn. Soc. Lond., vol. 25, 1894, p. 195. Parasierola nigrifemur Kieffer, Genera Ins., fasc. 76, 1908, p. 14. Perisierola nigrifemur Kieffer, Das Tierr. Lief. 41, 1914, p. 539. A single female of this was received from E. C. Green, of Brazil, with a note stating that it is parasitic on the larva of the pink boll worm. Xs this species is but little known the fol- lowing characters taken from the type will be useful : In Kieflfer's key in Das Tierreich will run to cellularis Say. Man- dibles quadridentate ; scape subequal in length with the second and third antennal joints ; second antennal joint one-third long- er than its apical width; third antennal joint with the apical width slightly greater than the length ; third and fourth an- tennal joints subequal, their length and apical width subequal ; ocelli in a curved line, the interocellar line half as long as the postocellar line. Perisierola emigrata, new species. Parasierola distinguinda Rohwer, Proc. U. S. Nat. Mus., vol. 41, 1912, p. 448. 1 2 INSECUTOR INSCITI.IJ M^NSTRUUS Parasierola cellularis Fullaway, Ann. Rept. Haw. Agr. Exp. Sta. for 1912, 1913, p. 24. Parasierola sp. Swezey, Proc. Haw. Ent. Soc, vol. 3, 1915, p. 101. This species, which has been reared in great numbers from the larva of the pink boll worm, by August Busck. is, as far as can be made out from the literature, still undescribed. It is apparently very closely allied to distinguinda Kieffer (::= cellu- laris Kieffer not Say) and is the same as the species recorded under that name in Proc. U. S. Nat. Mus., vol. 41, 1912, p. 448. Compared with Kieffer's description of distinguinda (as cellularis Say, Berl. Ent. Zeitscher., vol. 50, 105, p. 254) the following differences are noted : Third antennal joint not longer than wide ; apical joints of antennae blackish ; four pos- terior tibiae mostly black; wing veins very pale brown. From the other bethylid parasite of the pink boll worm, Perisierola nigrifemur (Ashmead), it may be distinguished by the relation of the ocelli to each other. In Kieffer's key (Das Tierreich, p. 533) it runs to cellularis Say. Female. — Length 2 mm. Head nearly as wide as the thorax, finely coriaceous and with a few large scattered punctures ; ocelli in a low triangle ; posterior ocelli less than their width from the occiput; interocellar line more than half as long as postocellar line; clypeal carina strong, complete; scape a trifle longer than second and third joints combined ; second joint one- third longer than apical width; third and following joints as long as their apical width ; pronotum narrowed anteriorly ; tho- rax shining, with very fine reticulations ; dorsal aspect of pro- podeum shining; posterior aspect shining or finely reticulate and with a faint median furrow; stigma truncate apically, but a very little longer than the parastigma. Black; flagellum ex- cept apical four joints, trochanters, and tarsi ferruginous ; tibiae brown, ferruginous at base ; wings hyaline, stigma and para- stigma dark brown, venation yellowish. Male. — Length 1.5 mm. Differs from female in being more shining and in the black tibiae and rather yellowish tarsi. Honolulu, Hawaii. Described from eleven (one type) fe- males and two (one allotype) males which were reared by Aug- ust Busck as a parasite of the larva of Gelechia gossypiella and INSECUTOR INSCITI^ MENSTRUUS 3 issued July 15, 1915. The specimens from Texas referred to under the name distinguenda and recorded as parasites of Bruchus prosopidis and Bruchus sp. are not considered as part of the type material, but the writer is confident that they are the same species. NOTES ON PERISIEROLA EMIGRATA ROHWER, A PARASITE OF THE PINK BOLL WORM (Hymenoptera, Befhyliidce) By august BUSCK This parasite was first observed in the Hawaiian Islands in 1912 and has undoubtedly been introduced only shortly previous to this time, possibly with the equally accidentally introduced host. It is, however, more probably an American species, in- troduced in 1910 from Texas in an attempt to establish effec- tive parasites of the seed infesting coleopterous larvae, which are injurious to the pods of algaroha {Presopis juliflora) ; these trees are grown in the Islands and the pods are collected and used as fodder for cattle. In 1915 it was found rather com- monly in all the cotton fields on the Island of Oahu and in the Kona cotton district on Hawaii and it is at present the only parasite of the pink boll worm of any importance. It is, how- ever, by no means an effective check and destroys only a small percentage of the cotton pest. The larva is an external para- site on the full-grown larva of gossypiella. The female works its way through the exit hole, cut by the boll worm before pupation, or through the lint of the opened boll into the cell, in which the boll worm is preparing to pu- pate, biting a hole in the cocoon, if necessary, with its strong mandibles. The parasite jumps on the back of the larva, which wriggles violently in an effort to shake its enemy off. It accomplishes this at times or manages to reach and kill the parasite with its jaws, but normally the parasite succeeds in curving its abdo- men around to the underside of the caterpillar and paralyzes it by inserting the sting into the nervous system, usually just 4 INSECUTOR INSCITI^ MENSTRUUS behind the thoracic legs. It then assures itself that the paraly- zation is completed by biting and pulling the skin of the cater- pillar, and after much deliberation it deposits its eggs. These are very large in proportion to the parasite, about one-half millimeter long, oblong oval, glassy white, and are normally placed one on a segment in two longitudinal rows on the under- side of the caterpillar. This, however, is not always the case; sometimes the eggs are placed on the back or on the side of the caterpillar. Four to six eggs are most commonly laid on one host larva, but in captivity three parasites laid 17 eggs each on three larvae, two laid 13 eggs, one 11, another 10, and still another 9 on single larvae. In each case all eggs hatched and developed to imagos. Six to 10 eggs on a larva were repeatedly observed in the field. These eggs hatch within 24 hours and the light reddish para- sitic larvae insert their heads into the caterpillar and grow rapidly, forming together a rosette on the shriveling body of the host. They become full-grown in two to three days and then spin their cocoons near the host larva. The spinning of the cocoon occupies nearly two days and before it is completed the larva voids a large fluid excrement through an opening left in the as yet unfinished cocoon. These excrements harden into a characteristic bifurcated black substance, which often serves to glue the cocoon to the supporting surface. When there have been many (8-17) parasites on a single lar- va their cocoons are flimsy, semitransparent, and white. When only four to six parasites have found nourishment in a single larva they average larger in size and their cocoons are much more substantial and brownish in color. The pupa of the parasite is at first white with coral red eyes, but turns blackish within a few days. During the summer- time in Honolulu the parasite develops in from 10 to 15 days after the egg is laid, but normally stays for a day within the cocoon, probably in order to harden in safety. The imago lives about two weeks and lays from 20 to 50 eggs, according to the host supply. INSECUTOR INSCITItE MI^NSTRUUS O A very large percentage of these parasites are females, about 30 to one male, and parthenogenesis was repeatedly observed, seeming in fact to be a normal condition. Reared females, which had been kept isolated each in a sepa- rate vial from the spinning of the cocoon and hence certainly virgins, would pounce at once on a gossypiella larva, introduced into the vial, paralyze it, and lay eggs. These eggs would always hatch, barring accidents, and would commonly produce all female offspring, which in turn would oviposit without copulation and again produce females. Four generations consisting exclusively of females were produced in one experiment from a single unfertilized female. The life history of this parasite is easily observed in cap- tivity by placing a host larva with the female parasite in a small vial. The parasites issued from caterpillars in stored cotton seeds would not fly away in search of growing cotton, but would search for new victims indoors in seeds. The spe- cies is, on the other hand, equally at home outdoors and readily finds its host in the bolls in the fields. The species is recorded in Hawaiian literature as Goniozus cellularis Say.

TWO NEW CRANE-FLIES FROM THE PHILIPPINE ISLANDS (Diptera, Tipulidce) By CHARLES P. ALEXANDER The following new species were included in a collection of crane-flies sent to me for determination by Mr. Nathan Banks. I am indebted to Mr. Banks for the loan of this material and for numerous other favors in the past. Tribe ANTOCHINI Genus ORIMARGULA Mik. 1883. Orimargula Mik; Wien. Entomol. Zeitung, vol. 2, p. 198. This genus has long been considered as being synonymous with Antocha O. S., but is a valid group. It curiously unites the characters of the more generalized Antocha with the special- ized groups, Orimarga and Diatrephu. The only species hith- erto described is O. alpigena Mik (1. c, p. 199-201, fig. 1) from the Australian Alps. Orimargula philippina, new species. Coloration brownish; wings whitish opalescent; the anal angle prominent; the fused portion of Ms-{-Cu^ short; basal de- flection of Cui far before the fork of M. Male. — Length, 3 mm. ; wing, 4.3 mm. Frontal prolonga- tion of the head reddish brown, the mouth-parts yellower. An- tennae dark brown, the flagellar segments elongate-oval. Head brown (if a bloom is normally present it has been destroyed in the type). INSECUTOR INSCITI^ MENSTRUUS 7 Thorax brown, the pruinosity lacking or destroyed, Halt- eres brown. Legs yellowish brown, the tarsi darker, wings whitish opalescent ; veins dark brown ; stigma narrow, quite indistinct. Venation : crossvein r weak, inserted on Ro-\-z ; i?4+5 before the r-m crossvein elongate, about three times the length of this crossvein ; basal deflection of M1+2 about equal to r-m; petiole of cell M^ very short, not more than one-half the length of the basal deflection of M^-f 1; I basal deflection of Cwifar before the fork of M, this distance equal to about one and one-half the length of the deflection. Anal angle of the wing prominent. Abdomen brown. Hypopygiun with the pleurites elongate, the appendages about half the length of the pleurites. Holotype, $ , Manila, Philippine Islands. Type in the collection of Mr. Banks. This curious fly differs from O. alpigena Mik in the small size and especially in the wing- venation, the elongate basal sec- tion of vein i?4-f-5, the short petiole of cell M^ and, especially, the great recession of the basal deflection of Cw^, in which character it is very like Orimarga. The milky white wings and the prominent anal angle are characters of Antocha. I believe Orimargula should be considered a valid genus. Tribe ERIOPTERINI Genus ERIOPTERA Meigen Erioptera (Erioptera) luzonica, new species. Coloration light yellow ; wing strongly suffused with yellow- ish, the veins darker. Female. — Length, 5 mm. ; wing, 4.5 mm. Rostrum dull yel- low ; palpi brown. Antennje brownish yellow, the flagellar seg- ments light brown, the scapal segments more shiny. Head light yellow. Thorax dull yellow, the prsescutal stripes rather in- distinct, the median stripe broad, dull orange, with a row of about eight stout bristles on either side. Pleura yellow with a sparse grayish white bloom. Halteres dull brownish yellow, brightest at the base, the knob dark brown. Legs dull yel- low, the tarsi darkened. Wings narrow for this genus of flies. 8 INSECUTOR INSCITI^ MKNSTRUUS light yellow; veins stout, yellowish brown, the cord darkest. Venation normal for this subgenus. Abdominal segments brown, the caudal and lateral margins of the tergites broadly yel- low ; ovipositor yellow, the tergal valves elongated, strongly up- curved. Holotype, 9 , Luzon, Philippine Islands. Paratype, 9 , with the type. Type in the collection of Mr. Banks. A NOTE ON CISTHENE {Lepidoptera, Lithosiids) By HARRISON G. DYAR Hampson treated this genus in 1900, in Volume II of the Catalogue Lepidoptera Phalaenae. In his supplementary vol- ume, published in 1914, he places Ruscido arida Skinner and Cisthene major Rothschild as synonyms of C. menea Drury, recognizes C. argentinensis Rothschild and C. triplaga Hamp- son, and omits all mention of C. criton Druce and C. hodeva Druce, doubtless because these last two species were incor- rectly referred to this genus and family. Hampson's table contains some inaccuracies. It may be amended and the new species added as follows : Fore wing with mesial orange band. Subterminal band broken into two patches. Large, stout species; median band broad ruficolUs Hiibner Small, slender species; median band narrow, argentinensis Rothschild Subterminal band entire. Subterminal band wide on costa, cutting across apex and parallel to outer margin below. Orange band on hind wing broad, half of wing or more, menea Drury Hind wing black with narrow orange band, cynossema Druce Subterminal band slender, lunate, uniform. A yellow subcostal ray on fore wing liinaris Walker No yellow subcostal ray moiion Dyar INSECUTOR INSCITI^ MENSTRUUS 9 Subterminal band shortened at tornus, rounded, spot-like. Abdomen wholly yellow above. Mesial band of fore wing broad, one-third of wing or more. Hind wing yellow on basal two-thirds, prusias Druce Hind wing with large basal spot, sometimes join- ing the outer border praxis Druce Mesial band of fore wing narrow. Hind wing yellow on basal half. Abdomen wholly yellow arida Skinner Abdomen dark gray below Chorion Dyar Hind wing black with yellow costal mark, qiiadrifasciata Walker Abdomen partly or wholly black above. Hind wing black with yellow costal mark, tehuacana Dyar Hind wing yellow on basal half cypris Druce Fore wing without mesial transverse yellow band. Fore wing with subterminal yellow band. Fore wing with mesial longitudinal yellow ray through cell. Mesial ray very broad cynara Druce Mesial ray slender or broken. Subterminal band slender, lunate trisigna Walter Subterminal band broken into three spots, triplaga Hampson Fore wing without mesial longitudinal r&y . .unicincta Hampson Fore wing without subterminal yellow band abdulla Dyar Cisthene monon, new species. Head, thorax, and abdomen yellow above ; legs and venter dark gray. Fore wing slaty gray; a narrow yellow mesial band and regular, curved subterminal one, running close to margin, less so at apex. Hind wing with a small gray spot at base, disk broadly yellow, terminal dark gray band reaching nearly half of wing. Expanse, 27 mm. Type, male, No. 21032, U. S. Nat. Mus.; Merida, Venezuela (S. E. Bricefio). Cisthene chorion, new species. Head, thorax, and abdomen yellow above, legs and venter dark gray. Fore wing slaty black; a moderately broad yellow 10 INSECUTOR INSCITI^ MRNSTRUUS band a little before the middle ; siibterminal band rather broad, curved, shortened at tornus. Hind wing with a small dark spot at base; outer border broad, covering half of the wing. Expanse, 33 mm. Type, male. No. 21033, U. S. Nat. Mus. ; Guadalajara, Mexi- co (B. Neumoegen). A specimen similar to this, except that the abdomen is yel- low below, is before me from the Chiricahua National Forest, Arizona (Poling and Duffner). It agrees well with the de- scription of arida Skinner, except that it is somewhat larger^ and it may be that species. C. chorion, also, may be the same as arida, but I do not venture to unite them on the material before me. I think that Hampson is clearly wrong in uniting arida with nienea. Cisthene tehuacana, new species. Head and thorax yellow ; abdomen black above, except at base and tip ; legs and venter black. Fore wing black, a little slaty, with narrow mesial yellow band and shortened lunate sub- terminal one. Hind wing black, a small yellow spot near mid- dle of costa. Expanse, 24 mm. Type, male, No. 21034, U. S. Nat. Mus. ; Tehuacan, Mexico, September, 1910 (R. Miiller). Cisthene abdulla, new species. Head, thorax, and abdomen black, the costa narrowly yellow in front ; legs and venter black. Fore wing black, slightly slaty, base yellow to the middle except a short black dash at base of costa. Hind wing black with a costal yellow ray on basal half. Expanse, 26 mm. Type, male, No. 21035, U. S. Nat. Mus. ; Cuernavaca, Mex- ico. September, 1914 (R. Miiller). INSECUTOR INSCITI^ MENSTRUUS 11 THE MOSQUITOES OF THE MOUNTAINS OF CALI- FORNIA (Dipt era, Culi cider) By HARRISON G. DYAR The territory explored covers the northern half of the Sierra Nevada mountains of California. In a previous paper (Ins. Insc. Mens., iv. 80-90, 191(3), I described six new species of Aedes occurring there. I will here notice all the species found in the mountains. Aedes tahoensis Dyar. In describing this species, I compared it with lasarensis Felt & Young and stated that it might be a variety of that species. The comparison should have been with pullatus Coquillett. Pullatus has the same mesonotal ornamentation as tahoensis, running somewhat darker than the specimens from the central Sierras. However, tahoensis from the Gold Lake region in Sierra and Plumas Counties is also dark, and there is prob- ably no line of demarcation. The male genitalia of tahoensis have a spine on the basal lobe; pullatus is described as without this spine; but a re- examination of the mounts of pullatus shows the spine dis- tinctly present. The genitalia, therefore, are the same, and hot different, as I was led to suppose when I described the species. The larva of tahoensis has the upper head hair in three, the lower single ; pullatus has both head hairs multiple.^ The dif- ference may be bridged by specimens in the intermediate terri- tory; but with present information it is necessary to hold the species separate. Pullatus is described from the Kootenai re- gion of British Columbia, in the Selkirk Range. I have ta^- ho'ensis from the northern part of the Sierra Nevada mountains of California and the lower part of the Cascades in Oregon. Careful exploration of the continuation of the Cascade Range ^Pullatus has the upper head hair in fours, rarely in fives; lower head hair in threes. 12 INSECUTOR INSCITI^ MENSTRUUS northward into British Cohimbia would be very useful in con- nection with this problem. The breeding places of taJweusis are peculiar : Closed pools without inlet or outlet, filled by melting snow, which usually be- come completely dry by the first of July. These pools are due to irregularities in the surface of the ground, where the ground is compact enough to hold snow-water for a few weeks. They have no connection with stream or lakes, though naturally com- moner in valleys. They are not marshy, but have firm margins, the water being held as in a bowl. The water is clear and cold, but must be of a comparatively rich nature from its enclosed state. These pools can often be recognized when dry. In August, 1915, I visited Fallen Leaf Lake and located such a hollow. In April, 1916, as expected, I found it full of water with numerous pupae of tahocnsis. This is the only species that I have found in these pools and they are always present in large numbers, making tahocnsis the commonest mosquito of the mountains while it lasts. PuUatns has the same habit, I believe ; but it is now 14 years since I observed pullatus, and my recol- lection is not as perfect as in the case of tahocnsis. There is no species found in the east corresponding to pullatus or ta- hocnsis. Specimens before me referable to tahocnsis have been taken as follows: Yosemite Valley, California, May 19. 1907 (D. J. Fullaway), May 14 to 19, 1916 (H. G. Dyar) ; Little Yose- mite Valley, California, May 18, 1916 (H. G. Dyar) ; Fallen Leaf Lake, Lake Tahoe, California, May 27 to June 24, 1916 (H. G. Dyar) ; Lily Lake, Lake Tahoe, California, June 16, 1916 (H. G. Dyar) ; Tallac. Lake Tahoe, California, June 17, 1916 (H. G. Dyar) ; Tahoe Tavern, Lake Tahoe, California, June 20, 1915 (A. K. Fisher); Summit, Placer County, Cali- fornia. July 3 to 7, 1916, July 19, 1915 (H. G. Dyar); Gold Lake Camp, Plumas County, California, July 19 to 22, 1916 (H. G. Dyar) ; Gold Lake, Sierra County, California, July 20, 1916 (H. G. Dyar); Crater Lake, Oregon, August 16. 1916 (H. G. Dyar). Certain specimens of tahocnsis from Gold Lake develop a INSECUTOR INSCITI^ MKNSTRUUS 13 very deceptive resemblance to trichurus Dyar, which species occurs in the Kootenai region, by having the rnesonotum very dark with a white lateral spot. However, in trichurus, there are three impressed dorsal dark bands and the lateral white spot is entirely in front of the lateral groove ;^ in tohoensis there are but two dorsal impressed lines and the white spot is on both sides of the lateral groove. Aedes hexodontus Dyar. Comparison of specimens shows that this species is identical in mesonotal coloration with lasarensis Felt & Young and im- piger Walker. The ornamentation is very variable, being gold- en yellow with two narrow lines of dark brown scales, or wholly golden yellow, or wholly brown. The form with the distinct brown lines resembles lasarensis, the form wholly yel- low, impiger. The larvae, however, are distinct from both of these species. The breeding places of hexodontus are marshy pools, filled by snow-water, often very shallow, never deep ; often small like the hoofprints of cattle. I found hexodontus plentiful in some cattle tracks in the edge of a marsh near Tallac on Lake Tahoe. The cattle tracks were filled by spring water; there were no hexodontus in the marsh itself, though other mosquito larvas were there. At the end of Fallen Leaf Lake, hexodontus was breeding in seepage pools in a hollow under poplar trees. The water here was a small stream of drainage from melting snow. At Summit, Placer County, a few hexodontus pupae were taken in a shallow pool in an open marsh with willow bushes. The water in these marshes is comparatively poor in organic matter as the pools are not enclosed and often have considerable current of water through them ; but the ground over which they are formed must give a certain richness. No form representing hexodontus was recognized in the col- lections made in the Kootenai region of British Columbia. This material was taken in 1903 and worked over by Mr. Co- quillett at a time when the specific characters of Aedes were 'Suture between the mesonotal prescututn and scutum. 14 INSECUTOR INSCITI^ MENSTRUUS not well understood. On going over the old material I find several specimens with pale golden, unhanded mesonotum, much as in one form of hexodontus. However, no determina- tion can be made, as the mosquitoes of the Selkirks and Sierras are quite different, several eastern forms occurring in the for- mer. Larvae and males will have to be compared, which are not at hand in the Kaslo material. Specimens before me, referable to hexodontus, have been taken as follows : Fallen Leaf Lake, Lake Tahoe, California, June 4 to 24, 3 916 (H. G. Dyar) ; Tahoe Tavern, Lake Tahoe, California, June 20, 1915 (A. K. Fisher) ; Summit, Placer County, California, July 3 to 5, 1916 (H. G. Dyar) ; Gold Lake, Sierra County, California, alt. 6,582 feet, July 20, 1916 (H. G. Dyar) ; Gold Lake Camp, Plumas County, California, July 19 to 22, 1916 (H. G. Dyar) ; Hoquiam, Washington, May 27. 1904 (H. E. Burke). Aedes increpitus Dyar. This species belongs to the cantons group, in which the adults often are indistinguishable by coloration, but the species sepa- rate easily by the male genitalia and larvae. In the east there are three species, stimularis Walker, Htchii Felt & Young, and abfitchii Felt, the former breeding in river pools and having a short-tubed larva, the two latter breeding in woodland pools and having long-tubed larvae. Fitchii and abfitchii have a ten- dency to a golden coloration of the mesonotum, especially on the shoulders ; stimulans is grayer. There is also a species, sansoni Dyar & Knab, described from Banff, Alberta. Of this no larva is known ; the male genitalia agree with abfitchii. Mr. Knab and myself associated as sansoni specimens from Kaslo, British Columbia, of which only females and larvae are known ; the larvae agree with abfitchii. It is possible, however, that at both Banff and Kaslo there is more than one species of the cantons group. However, on the showing made, sansoni must be con- sidered a synonym or a western form of abfitchii. Another form, vittata Theobald, was described from Pecos Canyon, New Mexico. Males and females were taken, but the male genitalia have not been made known. A wrong larva INSECUTOR INSCITI^ MENSTRUUS 15 was associated. This name can only be identified by further collecting. It is probably not the same as increpitus, although the possibility is open. The larva of increpitus has a short tube and frequents river valleys, like stimulans, but the genitalia differ. The color of the mesonotum is dark with gray scales at the angles, not yel- low ; but the character is not diagnostic. In the Yosemite Valley, in May, I found increpitus in vast numbers. The larvae were not only in the river pools, but oc- curred in woodland pools ; everything in the valley was full of them. The adults were out and males were seen swarming. At Fallen Leaf Lake, the species was breeding in wave pools be- hind gravel beaches at the northern or outlet end of the lake, in artificial holes over a supply pipe, and in a grassy pool in a meadow close at hand. At Clio, in the Feather River valley, adults were still flying in July. I also got adults in August at Tahoe Tavern at Lake Tahoe. The water in these river and wave pools, frequented by this species, is dilute. The river pools often have a current, while the lake pools are connected by seepage with the lake itself. The larvse come early, but are of slower development than the black-legged species, and can be found through June. Both males and females can be caught till late in the summer. Specimens before me, referable to increpitus, have been taken as follows: Yosemite Valley, California, May 14 to June 13, 1916 (H. G. Dyar) ; Little Yosemite Valley, California, May 23 to 28, 1916 (H. G. Dyar) ; Fallen Leaf Lake, Lake Tahoe, California, May 28 to June 24, 1916 (H. G. Dyar); Tallac, Lake Tahoe, California, June 17, 1916 (H. G. Dyar) ; Glen- brook, Nevada, August 25, 1915 (H. G. Dyar) ; Tahoe Tavern, Lake Tahoe, California, June 20, 1915 (A. K. Fisher), Aug- ust 15, 1915 (H. G. Dyar) ; Clio, Feather River, California, July 9 to 23, 1916 (H. G. Dyar) ; Pacific Grove, California, July 2, 1903 (Isabel McCracken) ; Eureka, California, May 6 to July 6, 1903 (H. S. Barber) ; Fieldbrook, California, May 26, 1903 (H. S. Barber). The last three localities are in the coast region of California 16 INSECUTOR INSCITI^ MKNSTRUUS and not the Sierras, and there is a possibility that there is a different species involved, no larvae being known. Aedes palustris Dyar. This species belongs to the cantons group, but it is distin- guishable as adult by the large number of white scales on the wings which invade even the fifth vein. Normally, the abdo- men is basally banded with white scales and a few apical white scales also; but a marked variety occurs in which there is a complete line of white scales down the back. I propose to designate this by the new name pricEi, in honor of Mr. W. W. Price, the proprietor of Fallen Leaf Lodge, to whom I am in- debted for many kindnesses. The variety pricei has a very marked appearance, quite strongly suggesting nigromaculis Ludlow, riparius Dyar & Knab, or euedes Howard, Dyar & Knab, but to which it is not allied. Type number for the va- riety pricei, No. 21043, U. S. Nat. Mus. The larva has a long tube and lives in grassy marshes. These larvae were in the marsh near Tallac referred to under hexo- dontus, and there Mr. Price assisted me to secure several. They were also in the meadow pool near the end of Fallen Leaf Lake referred to under increpitus. Several larvae were found in the Little Yosemite Valley in a pool which was flooded with rain at the time but was apparently originally a grassy meadow pool. Adults were flying in the high mountains about Gold Lake, south of Clio. Here the species palustris and increpitus were separated, there being no river or wave pools about Gold Lake and only river pools at Clio. Elsewhere, at Yosemite and Fallen Leaf, the species flew together. Specimens before me, referable to palustris, were taken as follows: Little Yosemite Valley, May 20 to June 2, 1916 (H. G. Dyar) ; Fallen Leaf Lake, Lake Tahoe, California, June 3 to 24, 1916 (H. G. Dyar) ; Lily Lake, Lake Tahoe, California, June 16, 1916 (H. G. Dyar) ; Gold Lake, Sierra County, Cali- fornia, July 20, 1916 (H. G. Dyar) ; Gold Lake Camp, Plumas County, California, July 19 to 21, 1916 (H. G. Dyar). Aedes vexans Meigen (syhestris Theobald). This widely spread mosquito occurred rarely in the Yose- INSECUTOR INSCITIvT; menstruus 17 mite Valley. The species is distributed over Europe and North America, being indigenous to both continents. Along the At- lantic seaboard it is one of the commonest species, especially toward the north, breeding in temporary woodland and road- side pools. Of the Yosemite specimens, one was caught May 14, 1916, the other bred from a woodland pool May 22, 1916, where it was associated with the ubiquitous increpitus. Aedes cinereus Meigen (fuscus Osten Sacken). This species also is common to Europe and America and, in the east, breeds in temporary woodland pools. In Yosemite it was bred from valley pools with increpitus and at Fallen Leaf from wave pools with the same association. It is thus a river valley species in the west. Previous records of this species from California are lacking, the westernmost record being Kaslo, British Columbia. The adult has the mesonotum golden brown with traces of two darker lines; abdominal bands narrow, but widening at the sides to form a white lateral line. The legs are without sprink- ling of white scales ; the male has short palpi. Aedes cataphylla Dyar. A very characteristic species, with the thoracic and abdomi- nal marking of increpitus, but with wholly black tarsi. The wing scaling also is peculiar. The eggs are much thicker than those of any other species in the Sierras. The male, larvse, and life history are unknown. This is the second earliest species to appear on the wing. When I arrived at Fallen Leaf Lodge, May 25, 1916, no mos- quitoes were flying except overwintering specimens of Culiseta. The first adult of the spring emergence was seen June 2, a specimen of ventrovittis. On June 4 cataphylla was out in numbers, mixed with a few tahoensis, and they continued to be taken till June 24, when I made my last catch at the lake. Specimens before me, referable to cataphylla, were taken as follows : Fallen Leaf Lake, Lake Tahoe. California, June 4 to 24, 1916 (H. G. Dyar) ; Lily Lake, Lake Tahoe, Califor- nia, June 16, 1916 (H. G. Dyar) ; Glenbrook, Nevada, June 5, 1916 (H. G. Dyar). 18 INSECUTOR INSClTly^ M^NSTRUUS Aedes varipalpus Coquillett. This species breeds in water in holes in trees. It is spread throughout California, both along the coast and in the Sierras, extending up to Washington and British Columbia and into the Kootenai region — wherever there are trees to hold water. Oaks are the most useful trees in this respect though probably alders, willows, and sycamores will serve also. The conifers do not hold water. The species was abundant in Yosemite Valley in May, more abundant than I have ever seen it before. Specimens before me from the Sierras, referable to varipal- pus, have been taken as follows : El Portal, California, May 12, 1916 (H. G. Dyar) ; Yosemite, California, May 13 to 18, 1916 (H. G. Dyar) ; Tahoe Tavern, Lake Tahoe, California, August 15, 1915 (H. G. Dyar) ; Homewood, Lake Tahoe, Cali- fornia, August 39, 1915 (H. G. Dyar) ; Glenbrook, Nevada, August 25, 1915 (H. G. Dyar). Aedes ventrovittis Dyar. This species is very early, being the first of the snow-pool species on the wing. At Fallen Leaf, in 1916, which was a very late season, a specimen was taken on June 2. Two others were obtained June 15, after which nothing more was seen of the species. I arrived at Gold Lake July 19, but saw nothing of ventrovittis at that time. Prof. W. B. Herms, however, who preceded me at Gold Lake, took several specimens of this spe- cies on July 4, it being the only mosquito flying. Gold Lake is about 500 feet higher than Fallen Leaf and about 75 miles farther north ; the season is consequently some three weeks later. The adults resemble hexodontus in coloration, having golden yellow scaled mesonotum, but are much smaller. Also the pres- ence of white scales on the wings and the ventral abdominal stripe distinguish them. The males and larvae are unknown. It will require very early collecting to obtain the life history, and this presents some practical difficulty, as none of the moun- tain camps are open early enough for this work. They are generally piled up with snow banks and uninhabitable. INSECUTOR INSCITI^ MIJNSTRUUS 19 Aedes fished, new species. Proboscis, palpi, and antennas black. Integument black ; head with sparse, narrow curved, bronzy brown scales on the vertex, small flat whitish ones on the sides ; many erected forked black ones on the nape. Mesonotum with sparse, coarse, narrow curved, bronzy brown scales, becoming straw-yellow around the antescutellar space and over roots of wings ; scales on pleura small, flat, whitish. Abdomen black scaled, with small irregu- lar, bands of white ones at the bases of the segments, narrowly cleft on the dorsal line, widening on the sides, but not covering over half of the segment ; penultimate segment with lateral patches only, last segment wholly black. Venter black scaled, the last two segments wholly black ; fourth segment with white scales at base, third largely white scaled on basal half. Legs black scaled, the femora whitish beneath ; femora, tibise, and first tarsal joint sprinkled with whitish scales. Wing scales black, a few white ones at base of costa and roots of first and fifth veins; outstanding scales long, slender, black, uniform. Six females, collected by Dr. A. K. Fisher of the U. S. Biological Survey, at Tahoe Tavern, at the outlet of Lake Tahoe, California, June 20, 1915. Type, No. 21042, U. S. Nat. Mus. This species is of the size of cinercus and ventrovittis. The male is unknown, but presumably has long palpi ; the mesono- tum is dark brown, not bronzy, and has no dark lines ; there are white scales on the legs and the abdominal bands do not join in a white lateral line. These characters differentiate it from cin- ereus. It is closest to ventrovittis, but the mesonotum is uni- formly dark brown, not golden yellow with more or less dis- tinct paired brown lines ; there are less white scales on the wings and the ventral black line of the abdomen is lacking. The species is of a different seasonal occurrence ; ventrovittis is early, none being seen at Fallen Leaf after June 15 of 1916, a very late season. Dr. Fisher took fisheri at Tahoe Tavern, a more advanced locality than Fallen Leaf, and in 1915, a normally early season. It is probable that fisheri did not ap- 30 INSECUTOR INSCITI^E MENSTRUUS pear in 1916 until July, which may be the reason why I missed this species entirely, as I left the mountains before then. Culiseta inornatus Williston. This species is typical of the low country and strays only sparingly into the mountains. It is abundant in Nevada in the valleys at the foot of the mountains surrounding Lake Tahoe ; specimens were taken in the mouth of Kingsbury Canyon. It was found breeding in muddy pools in a cow pasture near Glen- brook on the Nevada side of Lake Tahoe. This side has a more arid character than the California side, more resembling the sagebrush plains, with their irrigation pools, so favorable to inornatus. Culiseta incidens Thomson. Equally at home everywhere in the west, in the plains and mountains, breeding in any enclosed water from rain-barrels to mountain springs. Hibernated adults are the first mosquitoes seen in the spring, and breeding begins early. I found pupse already in May, 1916, in the Yosemite Valley, while many A'edes lucre pitus were no further advanced. At Gold Lake the larvae were in vast numbers in all stages, together with egg- boats, but many already in the last stage, in a marsh only re- cently vacated by A'edes hexodontns, on July 20, 1916. The species breeds all summer. I found them in an ice-cold mountain spring at Fallen Leaf, in August, 1915, where they were preyed upon by Bucorethra larvae. In May-June, 1916, they were again in the same spring, again preyed upon by Bucorethra. Culiseta impatiens Walker. This species was caught at Yosemite, Fallen Leaf, and Gold Lake. The enormous size of the adults is striking. There is no previous record of this mosquito from California, though it has a northern distribution, from Alaska eastward to the mountains of northern New York. Its occurrence in the Siei'-ras, therefore, was to be expected. The ]arv?e are known to inhabit cold spring pools and can be found all summer. The adults hibernate. INSECUTOR INSClTliE MKNSTRUUS 21 Culex tarsalis Coquillett. This species is abundant throughout the west, especially in the lowlands, breeding in all kinds of permanent and semi-per- manent pools, except open river-bed pools, taking readily to irrigation water. It occurs throughout the mountains, al- though in reduced numbers, favoring open warmer pools. Specimens were taken at Yosemite, Fallen Leaf, Lake Tahoe, and Gold Lake, in fact everywhere that I went. The eggs are laid in the usual boat-shaped masses and the adults are sup- posed to hibernate, although exact observations are lacking. On one occasion I collected recently dried sod from an irri- gated pasture at Steamboat, Nevada, and, on immersing the sod in water, three tarsalis larvae hatched. This would indicate that fragments of an egg-boat may exist on dry grass for a time. Whether or not there is normal habit shown here, I am unable to say. Culex saxatilis Grossbeck (terrifans Auct. non Walk.) This species is well known as an inhabitant of the Sierras, having been taken at Sisson, California, by Dyar and Caudell in 1906. Larvae were collected by me in grassy pools near Tahoe Tavern, Lake Tahoe, in August, 1915, and adults were caught in the Yosemite Valley in May, 1916. A NEW CTENACROSCELIS ^-^ {Tipulid(B, Diptera) By CHARLES P. ALEXANDER' The crane-fly described below is one of the largest, if not the very largest, member of its family. The allied Ctenacros- celis prcBpotens Wiedemann (Aussereur. zweifl. Insekt., 1, 40, 41, 1828, as Tipula) has long been considered to be the giant of the family ; but the wing of the female of prapotens barely at- tains a length of 40 mm., whereas the male of the new species measures at least as much ; the females are larger than the 'Contribution from the Entomological Laboratory of Cornell University. 22 INSi:CUTOR INSCITI^ MENvSTRUUS males in this tribe of flies and this sex of the new species, at present unknown, must be an immense insect.

A SYNOPTIC REVISION OF THE CUTEREBRID^, WITH SYNONYMIC NOTES AND THE DE- SCRIPTION OF ONE NEW SPECIES By CHARLES H. T. TOWNSEND The present paper deals only with those species represented by adult material in the U. S. National Museum, totaling 108 specimens. A careful study of this material has disclosed many errors which need correction. Certain species of the older authors have been misidentified, certain valid species names have been put in the synonymy, certain synonyms have been used as valid names, and certain aberrant specimens of old species have been described as new species. These errors are corrected in the notes which follow the table?. The followins: synopses will serve to separate the species treated. » SUBFAMILIES AND GKNERA 1.

Pseudogametes semiatra Wied. — Specimens of this most striking form, from southern Brazil, sent by Dr. A. Lutz, show INSECUTOR INSClTlyT; MENSTRUUS 25 on external characters that the genus certainly belongs in the Cuterebridse. Cuterebra cuniculi Clk. — I consider, with Brauer, that horri- pilum Clk. must be a synonym of this species. C. abdominalis Swenk is the same species. Cuterebra americaiia Fab. — There are several forms of this species in the east and west. The mesoscutum may be quite highly polished or with a very thin but distinct pruinosity, while the pleural pile varies from whitish to distinctly yellow. I took 14 males of the pruinose form along the stream in Hell Can- yon, Manzano Forest Reserve, New Mexico, at about 5,500 to 6.500 feet, September 14 and 17, 1916 ; and one male of the polished form on the Rio Ruidoso, Lincoln Forest Reserve, New Mexico, at about 7,000 feet, September 30, 1916. Many specimens of the pruinose form were taken by me in July, 1898, at the same point on the Rio Ruidoso, showing that both forms occur together in the same district. Cuterebra nitida Coq. is evidently a male of this species with an abnormally narrow front, while latifrons Coq. is evidently one with an abnormally wide front. C. polita Coq. is the same species, as is also the al- lotype (male) of lepivora Coq. Of the above, polita is the form with polished mesoscutum, while the others show some pruinos- ity. Specimens from Virginia, South Carolina, and Georgia show the mesoscutal pruinosity rather more distinctly and have the yellowest pleural pile. Cuterebra approximata Wlk. — Two specimens from Yuma and Phoenix, Arizona, are somewhat doubtfully referred to this species. Cuterebra atrox Clk. — From the description, similis Johns, is evidently this species. Cuterebra histrio Coq. — The holotype is from Guanajuato. Mexico. Many specimens of a form of this species were taken by myself in the Sierra Madre of western Chihuahua near Meadow Valley, at about 7,000 feet. The facio-genal pattern is intricate and peculiar. Bogeria princeps Aust. — C. lepusculi Towns, lepivora Coq. (holotype, female), and albifrons Swenk are evidently this 36 INSECUTOR INSCITI^ MENSTRUUS species. From the fact that the quite detailed generic and specific descriptions given by Austen fit the male of lepusculi exactly in every particular except the character of the arista, I was unable to repress the conviction that Austen's specimens had the arista denuded of hairs, especially since the very strik- ing pile coloration described is known to me in no other form. I accordingly wrote to the British Museum for information, and now take the liberty of quoting here the reply kindly sent me by Dr. Guy A. K. Marshall : "I have examined Mr. Aus- ten's type of Bogeria princeps, but, unfortunately, the head is in a dirty condition, and only one antenna is left. At first sight, the arista certainly does appear to be entirely bare, but, on examining it with a higher power, I find a portion of a hair on the basal half, and it seems to me extremely probable that the arista has really been denuded. In Mr. Austen's second speci- men both the antennse are gone, so that this does not throw any light on the matter." In the female the white pile of pleurae does not follow around the edge of scutellum and is lacking on base of abdomen. Some males also lack this pile on base of abdomen, while others show it conspicuously developed. The species reaches Arizona, California, Nevada, and New Mexico, and attacks both the jack rabbit and the cottontail. The genus is valid on facial characters, as described and figured by Aus- ten. Bogeria emasculator Fitch. — This is a valid species and en- tirely distinct from fontinella Clk. It is a parasite of squirrels and chipmunks. C. scutellaris Br. is the same species. It ap- pears to be restricted in range to the northeastern parts of North America. Bogeria fasciata Szvenk.- — This species seems to replace emasculator in the west, and has the same habits. It was reared by me from a larva taken in July, 1898, from the fore leg of a Tamias sp., on the Rio Ruidoso, New Mexico, the fly issuing the following May. The first-stage larvae of both this and the preceding species probably enter such part of the host as hap- pens to be most convenient, penetrating the scrotum when of- fered and not by invariable habit. The headless specimen in the U. S. National Museum labeled "Fitch's type" and "C. INSECUTOR INSCITI^ MENSTRUUS 27 emasculator" was so labeled under a misapprehension, as proved by its entire disagreement with the description. It is simply a specimen that had been wrongly so determined by Fitch, after describing his species. It is fasciata Swenk. C. fontinella Aus- ten (nee Clark), 1895, Ann. Mag. N. H., ser. 6, Vols. XV, XVI, is also this species. The location of Fitch's holotype of emasculator is unknown. It was probably sent to some corres- pondent. Little importance was attached to type specimens in this country in Fitch's day. Bogeria fontinella Clk. — There are three specimens of this species in the collection, from South Carolina, Florida, and Mississippi. It is a larger species than either of the two pre- ceding and decidedly broader, rather closely approaching buc- cata in both form and size and like it evidently confined to rab- bits. It may be at once distinguished from the squirrel flies by the pronounced gray pruinosity of the mesoscutum. At first sight, it appears identical with buccata, though slightly under- sized, but is at once known by its densely pollinose anal seg- ment. Bogeria grisea Coq. — This is a small northwestern form inter- mediate between emasculator and fasciata. Bogeria scudderi, new species. Length of body, 16 to 20 mm. ; of wing, 14 to 16 mm. ; width of thorax, 7 to 8 mm. Three males as follows, all reared from rabbits: Washington, D. C, fly issued March 4, 1895, larva collected by Mr. N. P. Scudder; Round Mountain, Texas, fly issued September 20, 1895, larva taken by Mr. F. G. Schaupp from leg of host; Beltsville, Maryland, larva collected by Mr. E. B. Marshall, November 24, 1911. (All det. Coqt. as buccata Fab.) Differs from buccata F. as follows : Narrower in form. Male front very narrow. Mesoscutum and scutellum chocolate color, clothed with short blackish pile, interspersed with a few grayish hairs along transverse suture. Abdomen chestnut-brown, the disk of tergum metallic and following the hind borders of seg- ments laterally. Wings less deeply infuscate. Pollinose spots not apparent on front. Holotype, No. 20953, U. S. Nat. Mus. 28 INSECUTOR INSCITI^ MHNSTRUUS Named in honor of Mr. N. P. Scudder, of the National Mu- seum Library, who collected the first specimen. Through the kindness of Dr. B. H. Ransom, Chief of the Zoological Laboratory, Bureau of Animal Industry, U. S. De- partment of Agriculture, I have had the opportunity to examine two third-stage larvae, taken from the throat of hogs, which I am able, by comparison with puparia, to identify as this spe- cies. The entire, strong, sharply-pointed, thorn-like spines of these larvae are distinctive of the rabbit bots of this group. The material is as follows : B. A. L Parasite Coll. No. 15614. — One specimen in situ in larynx of hog, Blacksburg, Virginia, collected by N. S. Mayo, July 22, 1910. The larva had embedded itself longitudinally in the wall of the larynx, on one side, even with the vocal chords. B. A. L Par. Coll. No. 18026.— One specimen from "larynx or pharynx" of hog, Birchwood, Tennessee, collected by B. J. Amerson, July, 1915. In the first case above, the larva was uninjured and had evidently reached its location through its own locomotory ef- forts, by working its way from the pharynx, mouth, or gullet. It is a question whether the hog in this case, in rooting among rabbit burrows, ingested the egg from which proceeded this larva ; or whether it ate the rabbit host containing this larva in the third stage, without incapacitating the latter, which was saved from being swallowed by its sharp spines and was after- wards able to make its way into the larynx. In the second case above, the larva appeared to have been injured by the teeth of the hog, indicating that the latter had ingested it either free or in situ in the rabbit host, but was unable to swallow it by reason of its very sharp spines piercing the oesophageal or pharyngeal membranes. SOME INTERESTING ORTHOPTERA FROM MEXICO By a. N. CAUDELL Among a small lot of Orthoptera recently sent in for deter- mination by Mr. Roberto Miiller from Presidio, Mexico, were INSECUTOR INSCITI^ MENSTRUUS 29 three species of some interest by reason of their rarity or not having them hitherto reported from that country. They are as follows : Sagona oi'ata Briinn. One 9 . Described from Costa Rica and since reported from Guatemala. This specimen from Presidio is, I believe, the first record of its being found in Mexico. Pyrgocorypha rogersi Sauss. & Pictet. One 9 . Described from Costa Rica and not before recorded from Mexico. Bncoptolophus herbaceus Bruner. One 9 . This handsome little grasshopper was described from central Mexico but has not been reported since. It was found in moderate numbers by its describer in fields about the outskirts of Mexico City. SOME NEW AUSTRALIAN CHALCID-FLIES, MOST- LY OF THE FAMILY ENCYRTIDiE • (Hymenoptera) By A. A. GIRAULT Genus COCCOPHAGUS Westwood Coccophagus ashmeadi Girault. perseus, new variety. Female. — In the analysis of the Australian species runs to ashmeadi from which it differs in that the club joints are sub- equal to funicle 3 and not longer as in nigriventris. The pro- notum is very slightly dusky, if at all. Two females (G. Compere). Habitat, Swan River, West Australia. Types, Cat. No. 20683, U. S. Nat. Mus. Coccophagus emersoni, new species.

Black, the wings hyaline, the scape and legs golden except proximal four-fifths of the hind coxa ; the following parts orange : Head, except a line between the lateral ocelli and most of the occiput; scutum, except the cephalic fourth ; parapsides, except a small spot cephalo-mesad a little cephalad of middle ; and scutellum, except at base mesad (a small area). Stature of trigiittatus. Most of propleurum 30 INSECUTOR INSCITI^ MRNSTRUUS and a roundish area below the tegula, yellow. Club distinct but not much wider than the funicle ; funicle 3 a little longer than wide, 1 nearly twice longer than wide; pedicel barely as long as funicle 3, subequal to club 2 ; all club joints wider than long. Flagellum (except the pedicel) longitudinally striate. Mandi- bles subtruncate, but three weak, obtuse teeth indicated. Three females in the collection of the U. S. National Mu- seum. Habitat, Perth, West Australia. Types, Cat. No. 20684, U. S. Nat. Mus., three females on tags with a slide bearing a head. Coccophagus australiensis, new species. Female. — Length, 1.25 mm. Agrees with the description of lunulatus Howard but the scutellum does not always bear the black area at apex and funicle 1 is a little longer than the pedi- cel; scutum and scutellum with rather dense, close, yellowish pubescence. The male, apparently, has no yellow on the body. From four females in the U. S. National Museum (G. Com- pere, 766). Habitat, Swan River, Australia. Types, Cat. No. 20685, U. S. Nat. Mus., two females on tags. Cotypes in the Queensland Museum, a female on a tag. Here is another one of those puzzling species, so similar to a species of another region yet with slight differences and prob- ably wholly distinct as to origin. The species is founded on the supposition that it is an aboriginal of Australia. Hence, if so, rooted in a stock wholly remote from that of lunulatus. Later I found that the Australian species differs in having the scutellum hairy. Genus ABLERUS Howard Ablerus emersoni, new species. Female. — Length, 0.75 mm., excluding the ovipositor, which is extruded for a length equal to a fourth or more that of the abdomen and is white at tip (the valves, that is).

Caudal margin of abdominal segments dusky. Fore wings with about nine lines of somewhat coarser discal cilia proximad of the hairless line and a small patch farther proxi- mad. Funicle joints annular, subequal ; club 1 a little longer than wide, not quite half the length of the club. Cephalic legs immaculate. Male. — The same but the fore wings bear only about six lines of discal cilia proximad of the hairless line, the body is smaller and the antennae only 4-jointed, the club long, solid, five times longer than wide, the funicle joint a little wider than long and rather closely united with the club.

Female. — Similar to capillata but the distal infuscation of the fore wing, usually isolated in that species, is here extended proximad around the caudal and cephalic margins, on the lat- ter more than halfway to the venation (still farther on the opposite margin). Thus, this area is connected with the broken oblique line from stigmal vein as well as with the two isolated marginal areas (one caudad, the other cephalad) and is consid- erably larger than in the other species.

DYAR and FREDERICK KNAB In the American tropics the water held by the leaf-bases of Bromeliaceae has been found to be the natural habitat of the larvae of three species of Anopheles. These species are closely related and of characteristic appearance, thus forming a small natural group within the genus. A fourth species, hitherto undescribed and differing only in a few details, is at har.d. While the larval habits of this fourth species have not been definitely established, its close resemblance to the others, and the fact that it occurs in forested regions, warrant the conclu- sion that its larvse occur in water-bearing bromeliads. The species under consideration may be separated as fol- lows: 1. Wing with four white spots involving costa and first vein 2 Only the two outer spots involving the costa neivai H. D. & K. 2.

Mesonotum elongate, pale gray pruinose, medianly with two narrow, straight, impressed black stripes, obsolete on posterior third; close to lateral margins a pair of broader black stripes, attenuated at both ends, narrowly interrupted beyond the mid- dle by an oblique gray line ; disk with scattered pale hairs, an- terior and lateral margins with a border of fine whitish scales. Scutellum narrow, collar-like, gray-brown, with dark marginal INSKCUTOR INSCITI^ MENSTRUUS 39 bristles. Postnotiim mule, brown. Pleurae blackish brown, with a transverse stripe and the lower portion whitish pruinose; coxae pale. Abdomen depressed, dull black, without scales, clothed with rather coarse black hairs, posteriorly denser at the sides and with pale luster. Wings hyaline, the veins marked black and white, the out- standing scales very narrow ; four large white costal spots in- volving costa and first vein, the second spot at about middle of wing, the fourth a short distance before apex ; a large white spot on the fringe at wing-apex at ends of second and third veins ; a white spot on the fringe at apex of lower branch of fourth vein, another at apex of upper branch of fifth ; a min- ute white spot at base of third vein, another at furcation of fifth ; basal portion of first vein with a long interrupted white streak, separated from first costal spot by a small black spot. Halteres with white stems and black knobs. Legs long and slender, black marked with white. Femora streaked with white, the hind pair with a black ring close to base ; tibiae white beneath to near apices, the extreme apices white ; front tarsi with the first three joints dorsally streaked with white, the first with black ring near base, the second and third with black basal rings, the last two joints wholly dark; mid tarsi with the four proximal joints dorsally streaked with white to near base, the first with black ring toward base, the fifth wholly dark; hind tarsi with the first joint ventrally streaked with white, a black ring near base and a broad white one at apex, the four distal joints white and with basal black rings.

INSECUTOR INSCITI^ MKNSTRUUS 41 THE BARNES & McDUNNOUGH 'XIST" (Lepidoptera) By HARRISON G. DYAR The gentlemen from Illinois have published again. For persons already under criticism, this is nothing short of an "overt act," and the temptation is strong once more to obtain their CaprcF hirci. However, this time I will temper my wind to the shorn lambs. The title is "Check List of the Lepidoptera of Boreal Amer- ica," which is distinctly misleading. Far more than the boreal region of America is included, the limits being the southern political border of the United States, excluding Porto Rico, the Virgin Islands, and the Canal Zone. But an element even of the tropical fauna is included in southern Florida and Texas. A list like this, without references, is useful inversely in pro- portion to the attainments of the student. This list, therefore, will be of especial value to beginners and amateurs. Yet it con- tains the result of much labor of a highly critical order in the determination of synonymy and deserves serious considera- tion. The list is founded upon my work in Bulletin 52, U. S. Na- tional Musuem, yet any mention of that fact is carefully omitted. This is doubtless intended as the frost which killeth, and perhaps I shall not survive. We will see. I presume the authors have an alibi ready and will say that they follow the list of John B. Smith, not mine. How much of Smith's list was cribbed from my catalogue, the dispassionate may decide. I will not leave the decision to Barnes & McDunnough. The sequence of families need not be commented upon ; it is unobjectionable. The Nolidse are transferred from the "Micros" to the Arctiidas, following Hampson. I do not think this is their proper position, although I appreciate the arguments in favor of it. Hiibner's "Tentamen" is discarded as "unpublished." I think this is an error. The Tentamen was printed and dis- tributed and was presumably obtainable from Hiibner himself while his edition lasted. I do not know what more is necessarv 43 INSECUTOR INSCITI^ MENSTRUUS to constitute publication. If the Tentamen was not published, neither is the "List" we are now noticing published, nor are Barnes & McDunnough's "Contributions" published. These things are printed, distributed and obtainable from the auth- ors, while the edition lasts. I do not know the size of the edi- tion authorized by the patronage of Miss Jessie D. Gillette; I do not know the size of Hiibner's edition of the Tentamen. I apprehend that the point is unessential. The fact that a ma- jority of European writers have discarded the Tentamen does not prove, to my mind, that the Tentamen should be discarded. The majority is not always right, nor is an appeal to the ma- jority always in order. An attempt has been made, in the Noctuidae, to restore the generic names on the basis of the old determinations of types, instead of the "first species" method arbitrarily used by Hamp- son. While I have personally favored this method, I did so only in case it was ofificially adopted, which will probably never be the case. We must abide by the rules of nomenclature al- ready established and, therefore, I think that this effort of Banies & McDunnough is highly to be commended. To cor- rect Hampson throughout will be a very difficult matter, deal- ing, as he does, with the world fauna. A few matters of detail that strike the eye may be noted. To criticise exhaustively, the list must be gone over name by name, a matter for which I do not consider the expenditure of time commensurate with the anticipated results. No. 45. A. Calient e Wright is lettered as a variety, but printed in synonymic type. AVhich is intended? No. 790, H. burnsi Watson should be listed as a of 789. See my recent note (Ins. Insc. Mens., iv. 131, 1916). No. 781. Thauma socialis Feisth. should be marked as doubt- fully North American ; its home is in Chili. There is no re- cent confirmation of its reported occurrence in British Colum- bia. No, 796. The determination should be revised. I do not think the form of Hylesia occurring in Arizona is alinda Druce. Unfortunately, I have no specimens at the moment. INSECUTOR INSCITI^ MENSTRUUS 43 No. 1028. Platyprepia does not belong to the Arctiidse. Its family is Hypsidse, which is the same as Pericopidae as here used. No. 2751. Deva ornata Ottol., for which I created the genus Rodrigucsia, is made a synonym of Chalcopasta howardi Hy. Edw., on the bold assumption that the type has a substi- tuted head, as explained by Barnes & McDunnough in a re- cent issue of the "Contributions." I have examined this head. It is too large; the vestiture is not quite consonant with the mesothorax ; the antennae are as bizarre for the genus as are the palpi and front; the type came from Dr. Ottolengui and was prepared by Mr. Jacob Doll, a notoriously clever patcher of specimens. Therefore I accept this synonymy, at least pend- ing the receipt of further material. No. 2754. A^. sagittalba Ottol. should be resurrected from the synonymy and listed as a good species as 2754, 1. It is larger than poetica and the costal stripe distinctly different. No. 2756. A^. pendula Ottol should be "a," not a strict synonym ; it may even be a distinct species. Judgment is diffi- cult, as material in this genus is distressingly scant. No. 3220. The subfamily beginning here is called Plusiinae instead of Hampson's unfamiliar Phytometrinse. No. 3228. The subfamily name Erebinge is adopted to re- place Hampson's Noctuinae. No. 3360. This is a synonym of A. rcpugnans Hubner (see Proc. U. S. Nat. Mus., 47, 425, 1914). No. 2SiQ4:. This species is called fimbriago Stephens, a name not found in Hampson or Staudinger. Whether it is earlier or later than xanthindyma Boisduval, I cannot say without study- ing over Stephens' works and repeating the labor already per- formed by Dr. McDunnough. Original synonymy like this should not be given in a list where all references are omitted. Xanthindyma plainly applies to this form, as Boisduval says in his original description of Cosmophila: "Antennes legerement pectinees dans les males" (Faun. ent. Mad., 94, 1833). Barnes & McDunnough, in a highly excited paper (Cont. Nat. Hist. Lep. N. A., ii, No. 5, 1914), tried to show otherwise and fran- tically quoted Hampson. I never paid any attention to this 44 INSECUTOR INSCITI^ MENSTRUUS paper, as it was obviously executed with a personal animus and the slurs and derogatory remarks at my expense show that any statements it might contain with reference to species de- scribed or synonymy established by me would have to be taken with a grain of salt. In this case, if fimbriago Stephens is older than xanthindyma Boisd., no harm has been done; if the reverse is the case, my forbearance has resulted in the per- petuation of an error. No. 34fi4. This is called latipalpus Walk., which synonymy was unnoticed by Schaus (Proc. U. S. Nat. Mus., 50, 373, 1916). This is presumably Hydrclia latipalpus Walk. (Cat. Brit. Mus., XV, 1763, 1858) described from an unknown local- ity. This synonymy should have been specifically published, s No. 3726. Apatelodes is referred to the Eupterotidae with- out question. I think this action is somewhat premature. No. 4982. Hellula phidealis Walker might properly be add- ed, as it occurs in the south. Localities before me are : Key West. Florida (Nat. Mus. coll.); Miami, Florida (Schaus coll.); Everglade, Florida, April 10, 1912 (J. A. Grossbeck) ; Browns- ville, Texas, May 17, 1904 (H. S. Barber) ; Augusta, Georgia, October 17, 1898 (U. S. Dept. Agric). No. 5009. This synonymy is too sweeping. 5. singhalis Walker, from Venezuela and the tropical mainland generally, is distinct from huronalis Guen. (serinalis Walk.) from North America and the Greater Antilles. (See Proc. U. S. Nat. Mus., 38, 272, 1910.) No. 5307. This species is a synonym of holoplKvaUs Hamp- son. In pointing this out (Ins. Ins. Mens., i, 105, 1913). I could not find the reference to Hampson's description. It will be found, however, under date of 1904 (Ann. Mag. Nat. Hist., (7), xiv, 181, 1904). No. 5455. This is synonymous with Corcyra ccphalonica Stainton, as pointed out to me by Mr. August Busck. Dr. Chit- tenden sent me only dwarfed specimens for determination in which venation was reduced, although he had normal large ones in his possession. I therefore feel more like blaming Dr. Chit- tenden than myself for the synonymy, although not wishirig to make a scapegoat of anybody.

Type, male, No. 21058, U. S. Nat. Mus., selected from 26 males and 35 females, bred from larvae in large, conspicuous, unsightly nests on a bush growing rather commonly in the wild country, New Providence Island, Bahamas, February and March, 1915 (H. G. Dyar). The larva is brown with faint longitudinal stripes, a broad subdorsal one being distinct. Tubercle iib on joint 3 and iii on joint 12 are much enlarged. A detailed description of the setal pattern is appended, pre- pared by Mr. Carl Heinrich, who has lately made a special study of the matter. The samples which I preserved of the food plant for de- termination have been lost or mislaid, so its name cannot be stated at this writing. A native of the island called it "wild cassava." This Phycitid occurs also in Cuba. I have 3 males and 16 females taken by Mr. Wm. Schaus at Santiago, in June, July, August and October, 1902. The male is more darkly shaded than in the form from the Bahamas, the dark markings ex- tended, reducing the gray ground to one or two patches. The female seems a little brighter than the Bahamas form, the ocherous shade before the inner line being always distinct; but there is no constant difference. 48 INSECUTOR INSCITI^ MKNSTRUUS GENERIC DESCRIPTION OF LARVA OF ANEG- CEPHALESIS DYAR (Type A. cathceretcs Dyar) {Lepidoptera, Pyralidcp) By carl HEINRICH Head capsule spherical, nearly square in outline viewed from above, slightly wider than long; greatest width back of mid- dle of head ; incision of dorsal hind margin about one-sixth the width of head ; distance between dorsal extremities of hind margin a little more than one-third the width of head.

APRIL-JUNE, 1917 Nos. 4-6 AN ANNOTATED LIST OF THE THYSANOPTERA OF PLUMMER'S ISLAND, MARYLAND By J. DOUGLAS HOOD Nine miles above the city of Washington, in the Potomac River, is the home of the Washington Biologists' Field Club, a little island of 12 acres known as Winnemana or Plummer's Island. From the lodge, 75 feet above the w^ater, it slopes precipitously on the south to the edge of the Potomac ; on the north and east to a low, forested flood-plain ; while toward the west it is more irregular in contour, with typical upland hard- woods, scattered pines and junipers, and isolated rocky patches overgrown with such plants as Opuntia and poison ivy. Charming and convenient of access, it has become a favorite collecting spot for local entomologists, and in the scientific literature of the last decade there have been recorded from these 12 woodland acres more than 100 new insects, for whose reception have been erected 13 new genera and 2 new families. The Thysanoptera, however, received no attention until Jan- uary, 1912, when, through the kindness of Mr. W. L. McAtee, the author made his first visit to the island. Since that date many hundreds of specimens have been taken, until at present 57 species are known from the island itself, in addition to several unidentified uniques not here listed. Seventeen addi- tional species have been taken within a few miles of the island — some, indeed, within a few yards. All of the latter probably occur here while several others, at present unknown, doubtless await discovery. 53 54 INSECUTOR INSCITI^ MRNSTRUUS This list, confessedly lacking in many forms which occur commonly in the immediate vicinity and whose ecological re- quirements are fully met at some place on the island, is of especial interest when compared with Dr. Hinds' total of 37 species for all North America,^ with Moulton's 24 for the State of California,^ and with Shull's 21 for Huron County, Michigan.^ It is interesting to note, too, the figures given by some of the more extensive lists : Uzel'* has 100 species from Bohemia; Renter^' has 07 from Finland; Bagnall,^ 74 from the British Isles; Buffa,'' 'M from Italy; and Moulton,^ 118 from North America. Using the totals given in this list in comparison with the number of Coleoptera known from the island, from North America and from the world, some interesting results are secured. The Coleoptera were selected for the reason that they are one of the best worked and most representative or- ders of insects, and because those of the island have been studied intensively. If they be used as the basis for calcu- lation, and the number of species known from the island (now about 1,390), divided by the number of species of thrips (57), and the total number of species of beetles described from North America (19,000), divided by the quotient (22.G), we 'Hinds, Warren Ivlmer: "Contribution to a Monograph of the Insects of the Order Thysanoptera inhabiting North America," Proc.

Assuming again that the same proportion exists throughout the world, and that there are 150,000 described Coleoptera, we get 0,037 as the total number of Thysanoptera which will have been described from the world when that order is as well worked as the Coleoptera are at present. Certainly not more than four-fifths of the North American nor half of the world's Coleoptera are known. At this proportion the North American Thysanoptera will, when described, total nearly 1,200, while the number of species in the world will fall only slightly short of 13,000. If, instead of the beetles, the birds be taken as the basis for calculations, and the assumed number of North American Thy- sanoptera (1,200) multiplied by 25 (the proportion existing between the avifauna of the world and that of North America), the result is 30,000 species of Thysanoptera. After taking the mean of several such estimates, the author, in 1915, in a paper read before the Biological Society of Wash- ington, placed the number of existing forms of thrips at 25,000.1 This is considerably less than Mr. C. B. Williams' estimate made to the author in 1914. He is of the opinion that nearly 50,000 species will ultimately be described.

DYAR I have gone over rather carefully the Pyraustinae listed in Barnes & McDunnough's recent "List." The omissions and errors are not as insignificant as I had anticipated, and may profitably be noted. I use this opportunity to add a few new records. 4910. Glaphyria rcniculalis Zell. has been transferred to Bgesta Ragonot. I think it should be returned to Glaphyria. The generic differences given by Hampson of the pectina- tion of the median vein of hind wing are unsatisfactory, but ' there remains the difference in length of the maxillary palpi. These are long in Bgesta and short in Glaphyria. Now in reniculalis the maxillary palpi are plainly short. 4903. On the other hand, reluctalis Hulst should go to Bgesta, as the maxillary palpi are long. It will come very close to simplicialis Kearf. (Can. Ent., xxxix, 4, 1907), which is obviously nothing but reluctalis with the white inner band replaced by a dark shade. 4906. My single specimen of basiflavais B. & McD., taken at Palm Beach, Florida, January 27, 1900 (H. G. Dyar), is unfortunately, without a head; but veins 10-11 are stalked and therefore the species cannot be placed in Lipocosma where its general appearance would make it seem more at home. 4907. Glaphyria dualis B. & McD. has the maxillary palpi about as long as the labial palpi and should be transferred to Bgesta. 70 INSECUTOR INSCITI^ MENSTRUUS 491(i. Symphysa adelalis Kearf. (Journ. N. Y. Ent. Soc, xi, 145, 1903) is correctly transferred to Lipocosma. 4913, 1. Lipocosma diabata, new species. White, uniformly shaded with brown ; lines slender, brown, not defining a central darker area as in sicalis Walker ; inner line excurved subcostally, coarsely dentate; outer line ex- curved above, inbent at vein 3 ; reniform an ellipse ; a ter- minal broken black line. Hind wing with the costal area white ; outer line slender, black, inbent at vein 2 ; black powdering in median space below the cell. Expanse, 14 mm. Type, female, No. 21151, U. S. Nat. Mus. ; Florida (Schaus coll.). 4921,1. Desmia nominabilis Hering (Stett. ent. Zeit., Ixvii, 55, 1906) is omitted. The supposed species I believe to be only a variety of D. funeralis, probably the same as subdivisalis Grote ; but the name should be cited. 4950. Hey dele pta futillalis B. & McD. is obviously a synonym of Syngamia haemorrhoidalis Guen. 4944. Conchylodes ovulalis Guen. is correctly identified. This name is not a synonym of platinalis Guen. as given in my list (No. 4297). C. platinalis is a distinct species which has not yet been recorded from the United States. 4952,1. Bocchoris rehamalis Dyar (Proc. U. S. Nat. Mus., xlvii, 393, 1914) may be added. I have a specimen from Kerrville, Texas, May 31, 1906 (F. C. Pratt). 4957. Nacoleia hampsoni B. & Mc.D. occurs also in Cuba and it may prove to be one of Herrich-SchafiFer's unrecognized species (listed by Hampson, Proc. Zool. Soc. Lond., 1899, 287 et seq.). Hampson would place this in Lygropia, as he has all the species allied to it. One of my Florida speci- mens bears a label in Schaus' writing: "Near Lygropria xanthogonalis Hamps." I do not find that Hampson has published this name, but he may have done so. The matter should be kept in mind. 4964. Sylepta masculinalis B. & McD. is not before me, but the figure and description agree so completely with Syngamia INSECUTOR INSCITI.^ MENSTRUUS 71 micromphalis Hampson that I have no hesitation in pro- nouncing it a synonym. 4965. Sylepta hrumalis B. & McD. is quite obviously a syn- onym of S. cephalis Walker. 49G2. I have seen no specimen that would agree well with Lederer's figure of fluctuosalis. The species in our collection over this name is Sylepta silicalis Guen. (see Hampson, Proc. Zool. Soc. Lond., 1898, 720, for synonymy), which name should be added to the list. 4966, 1. Sylepta miamialis Schaus. I do not find that a de- scription has been published. "Sylepta miamialis, n. sp. — Dark vinous red ; head with a whitish vertical spot ; venter and legs white. Fore wing dark vinous red, darkest on the basal half of costa ; discal mark reniform, dark purple; inner line invisible, outer line faint and slender, curving outward around cell ; a dark terminal line ; the fringe gray. Hind wing sordid, stained with dark vjnous outwardly ; a small gray discal dot. Ex- panse, 21-23 mm. "Miami, Florida (W. Schaus), 1 male, 2 females. Type. No. 21153, U. S. Nat. Mus.— W. Schaus." 4985. Sameodes adipaloides G. & R. should be given varietal rank, I think. j ' 5047, 1. Syngamia florepicta ' Dyar should be added. . I have specimens from Raleigh, North Carolina, August 5, 1907 (C. S. Brimley) ; Hattiesburg, Mississippi, June 18, 1915 (J. W. Champlin). 5055. Metasia argalis Fernald is made a synonym of D. ele- gantalis Warren. I think this is incorrect. Specimens of elegantalis, identified by Fernald, differ conspicuously from argalis, the type of which is before me. Among other things, the reniform of elegantalis is filled with white, while argalis has a dark gray reniform. The hind wings also dififer. 5052 and 5056. Diasemia zephysalis B. & McD. and Diasemia Icucosalis B. & McD. correspond closely to D. particolor Dyar and D. ernhesccns Hampson, from Mexico, but are dis- tinct on details in both cases. I have D. leucosalis also from 72 INSECUTOR INSCITI^ MENSTRUUS Mexico: Popocatepetl Park, Mexico, 8,000 feet, June, 1906 (W. Schaus). 6057. Diasemia fenestralis B. & McD. is not before me, but the figure looks as if the species belonged in the genus Clupeosoma Snellen of the Hydrocampinse. A re-examina- tion of the venation will decide. It seems close to C. lavinia Schaus (Ann. Mag. Nat. Hist., (8), ix, 679, 1912), differ- ing chiefly in the lack of widening of the inner line on inner margin. 5057, 1. Ischmirges chromaphila Dyar should be added. I have specimens from Santa Rita Mountains, Arizona, May 25, 1898 (E. A. Schwarz) ; Southern Arizona (O. C. Poling) ; Cochise County, Arizona, September 30 and October 7, 1904 (through G. Franck). 5081. Titanio helianthiales Murtfeldt (1897) should have as synonym, Pionea thyanalis Druce, Biol. Cent.-Am., Lep Het., ii, 557, 1899. Titanio murmuralis, new species. Fore wing dark gray, marked with pure white ; a subter- minal line starts from near apex, curving close to margin, oblique below to middle of inner margin ; cell white with two black lines ; costa and submedian fold white to two- thirds ; all the veins beyond cell radially white lined ; a black terminal line, preceded by white ; fringe white with two gray interlines. Hind wing gray with whitish outer line ; fringe as on forewing. Expanse, 12 mm. Type, female, No. 21293, U. S. Nat. Mus. ; Sabinal, Texas, March 2. 1911 (F. C. Pratt). Close to T. helianthales Murt., but smaller, the outer line narrower and more sharply drawn, the veins white-lined. 5104. Cindaphia angustalis Felder. The correct name is au- giistalis F. & R. Hampson's uncorrected typographical error (Proc. Zool. Soc. Lond., 1899, 245) has been copied both here and in the "Contributions," ii, 224, 1914. 5092. Phlyctaenia riisticalis B. & McD. closely resembles Pionea detersaUs Walker. I do not make the synonymy positive because I have detersaUs only from Ecuador and INSECUTOR INSCITI^ MENSTRUUS 73 Peru and do not know if it ranges to the Mexican Plateau. 5132, 1. Pyrausta fumipennis Warren (Ann. Mag. Nat. Hist.,^ (6), ix, 392, 1892) is omitted. It was described from Cali- fornia. 5153. Walker's orphisalis seems to have been misidentified in my catalogue. Barnes & McDunnough apparently recognize both this species and ochosalis Dyar ; but Schaus has labeled a specimen of ochosalis: "Pyrausta orphisalis Walk., comp. B. M." I suspect, therefore, that there is but one species concerned. 5177,1. Pyrausta achroalis Hampson (Ann. Mag. Nat. Hist., (8), xii, 26, 1913) should be added. I have a specimen from Miami, Florida (W. Schaus). The species looks quite out of place in Pyrausta and perhaps a separate genus may be justified. 5177, 2. The genus Boeotarcha Meyrick should follow here with two species: B. demantrialis Druce (Biol. Cent.-Am.. Lep. Het., ii, 270, 1895), which I have from Newark, New Jersey, August 23, 1899 (A. J. Weidt) ; Pittsburgh, Pennsyl- vania, July 30 and August 4, 1906 (H. Engel) ; New Brighton, Pennsylvania, August 21, 1902 (H. D. Merrick) ; Cove Mountains, Pennsylvania, July 27 and August 3, 1913 (E. Daecke) ; Kerrville, Texas, September, 1906 (H. Lacey) ; Southern Arizona (O. C. Poling). 5177, 3. B. stigmosalis Warren (Ann. Mag. Nat. Hist., (6), ix, 209, 1892), which I have from Miami, Florida (W. Schaus). 5177, 4. Also Azochis Walker, with one species, A. rufidis- calis Hampson (Ann. Mag. Nat. Hist, (7), xiv, 186, 1904)» =cubanalis Hampson (Ann. Mag. Nat. Hist., (8), xi, 337, 1913), which I have from Miami, Florida (W. Schaus). 5181. After studying Warren's description, I cannot see in Cornifrons pulveralis anything more than a form of simalis Grote. The home of the typical simalis is the Rocky Moun- tain region of Colorado. In the Great Basin it takes a smaller, lighter form, pulveralis Warren. I have this form from Placer County, California, June (through C. V. 74 INSECUTOR INSCITI^ MENSTRUUS Riley) ; Bluff, Utah, June 13, 1898 (Mrs. H. M. Peabody) ; Southern Utah, July, 1900 (O. C. Polii , ; Williams, Ari- zona, July 19 (Schwarz & Barber). Farther south a form occurs for which I propose the name Cornifrons sideralis, new variety. Uniform iron-gray, the black and white scales evenly mixed ; inner line running out sharply almost to the discal dots ; subterminal white mark narrow and straight. Type, female, No. 21155, U. S. Nat. Mus. ; Argus Moun- tains, California, April, 1891 (A. Koebele). Also another female from the same place and a third, in poor condition, Arroyo, 10 miles west of La Luz, New Mexico, August 33 (Townsend & Cockerell). Again, in the north, another form occurs which may be called Cornifrons praeia, new variety. Violaceous gray,' uniform, the ground not appearing white, the markings fine and brown. Type, male. No. 31156, U. S. Nat. Mus. ; Pullman, Wash- ington, May 10, 1895 (C. V. Piper). Also two males from the same locality, May 11, 1898 (Wash. Exp. Station, Nos. 316 and 827). 5181,1. Cornifrons phasma, new species. White, with very pale ocherous shades, at base and in median space; inner line oblique, brown, not reaching costa or margin ; no discal dot or a trace ; outer line brown, den- ticulate, slightly excurved over cell ; a line of purplish shad- ing from apex running to outer line below. Hind wing white ; a pale fuscous outer line close to terminal pale fus- cous border. Expanse, male 35 mm., female 21 mm. Types, male and female, No. 21157, U. S. Nat. Mus.; Los Angeles County, California, May (D. W. Coquillett). Cornifrons chlorophasma, new variety. Entirely white with a faint ocherous tint, all the markings absent. INSECUTOR INSCITI^U MENSTRUUS 75 Type, female, No. 31158, U. S. Nat. Mus. ; Argus Moun- tains, Californ ^ April, 1891 (A. Koebele, through C. V. Riley). This species, in both forms, differs easily from simalis Grote in the shape of the frontal process, which is not simply hood-shaped and scaled, but runs out into a bare, quadrate vertical blade. NOTES ON NORTH AMERICAN NYMPHULIN^ (Lepidoptera, Pyralidce) By HARRISON G. DYAR Elophila fulicalis Clemens. Cataclysta fulicalis Clemens, Proc. Acad. Nat. Sci. Phil., xii, 217, 1860. Cataclysta angtilatalis Lederer, Wien. ent. Mon., vii, 453, 486, 1863. This species can be distinguished from opulentalis Led. by the presence of a small black discal dot on fore wing and the absence of a distinct narrow dark line on hind wing. Opulen- talis has a discal ringlet, not a dot. The following may be races of fulicalis, but for the present, I give them specific rank. Elophila satanalis, new species. Fore wing with the base brown ; subbasal line white, dif- fused ; a broad brown band, stained with orange in the middle, followed by a straight white line with dark outer edge ; middle field brown above, irrorate with black below ; a blackish discal spot in a brown cloud ; an orange line from discal dot to tornus ; oblique subapical and subterminal white lines separated by an orange spot ; terminal band orange.

Elophila truckeealis, new species. Fore wing with the base brown; subbasal line white, dif- fused ; a broad brown band with slight luteous dilution cen- trally; median line white, angled subcostally in the female, straighter in the male, though flexuous, followed by black; a black discal dot with a little orange beyond it; middle field brown above and along median vein, irrorate with black below ; a short white outer line from vein 2 to inner margin, edged with black within ; subapical oblique white band slender, curved; subterminal half-line white; terminal line orange.

Mr. Schaus has labeled a specimen : "moniligeralis Led. Comp. B. M." Certainly Lederer's figure does not suggest this identification. However, the probability is that the figure is a product of the artist's imagination, at least the part beyond the middle of the fore wing, for Lederer says : "die aussere [Linie] an meinem etwas verwischten Exemplare nicht ganz bestimmt zu erkennen." Doubtless the whole half of the wing was il- INSECUTOR INSCITI^ MENSTRUUS 77 legible in the single male type ; but the artist had to draw something, and hence the strange pale border with inward curve below. Lederer's description makes no mention of this. Elophila cancellalis, new species. Fore wing white, but the markings predominant ; base filled with dark brown ; a white subbasal line, angled on vein 1 ; a broad dark brown band, followed by a white mesial line and a narrow brown line, angled in cell and on vein 1 ; middle area white, shaded with brown on costa ; traces of powdery orbicu- lar and reniform; outer line brown, slender, oblique, in a white space to vein 4, retracted and roundedly incurved to vein 1, then oblique to the inner margin ; terminal space dark-filled ; a white subterminal line to vein 2 ; an orange terminal line, edged by brown on both sides.

NOTES ON NORTH AMERICAN SCHCENOBIIN7E (Lepidoptera, Pyralide) By HARRISON G. DYAR In their recent "List" (No. 5306), Barnes & McDunnough would sink Scirpophaga consortalis Dyar as a synonym of repugnatalis Walker. This is incorrect; repiignatalis has a distinct design of transverse blackish lines, a large reniform outlined in dark, sometimes filled with sordid silvery, and small silvery spots in the fringe. In consortalis there are no transverse markings whatever, while the fringe is without white dots. Rupela albinella Cramer. Tinea albinella Cramer, Pap. Exot., iv, 163, pi. 372, f. D, 1782.

Professor Fcrnald's determinations, with marks of doubt attached, show that he recognized these forms as different, but preferred to associate them with an allied species rather than return them to the museum labeled "new" on his au- thority. Patissa parthenialis, new species. Fore wing silvery white, crossed by yellow bands with pow- dery brown edges ; an oblique streak at base, not attaining costa ; an oblique band of three patches, cut by vein 1 and median vein, the uppermost patch in the cell; a less oblique band in middle of wing, ending in a blotch at end of cell ; an outer band and a submarginal band, broad, parallel to outer margin. Hind wing white with three powdery blackish streaks crossing submedian fold. Expanse, 14 mm. Type, female, No. 21173, U. S. Nat. Mus.; Vernon Parish, Louisiana, July (G. Coverdale, through W. D.

While the female type has vein 7 arising after 9 and there- fore falls in Macrotheca, a male from the same breeding has 7 arising before 9. Moreover, specimens from Stockton, Utah, and Reno, Nevada, have 7 before 9, so that I think the vari- ation of the type is abnormal and that the species should fall in Alpheias. Macrotheca leucocope, new species. Pale gray, powdery on a nearly white ground, the veins darker toward base ; a white ray along median vein, widening to end of cell, where it terminates ; a terminal dark line, hardly broken. Hind wing dark gray, fringe pale. Expanse, 19 mm. Type, male. No. 21176, U. S. Nat. Mus.; Denver, Colorado (W. Schaus).

Grayish straw-color, the veins narrowly straw-color ; costa straw-color; a gray shade through the cell and outward to INSECUTOR INSCITI^ MENSTRUUS 85 margin ; a rather large rounded black discal dot ; a row of minute terminal black dots between the veins ; fringe inter- lined. Hind wing gray, a little lighter at extreme base. Ex- panse, 16 mm. Type, male. No. 21180, U. S. Nat. Mus. ; Yuma, Arizona, July 24, 1916, bred from larvae in wheat stems (T. D. Ur- bahns). Chilp loftini, new species. Apex of fore wing acute ; whitish straw-color, the veins light, edged on each side by a line of fine brown scales, which dif- fuse in the interspaces ; a small black discal dot ; a row of terminal black dots in the interspaces, connected by a slender line ; fringe interlined with brown. Hind wing white with a slender brown line on apical half. Expanse, 23 mm. Type, female, No. 21128, U. S. Nat. Mus.; Oknndale, Ari- zona, September 1, 1914 (U. C. Loftin), bred from Mexican cane. The male is much smaller, expanse, 15 mm. Other speci- mens were bred from Louisiana cane, in the same locality. The species is allied to C. multipunctellus Kearfott, but is not as white and is more distinctly and clearly marked. It looks very much like Platytes densellus Zeller, but the front is strongly tuberculate, which is not the case in that species. Platytes dinephelalis, new species. Fore wing white, the costa and inner margin broadly shaded with creamy brown, shading to dark brown just before the white area, appearing as two brown clouded bands, one through the cell, curving up to apex, the other along sub- median fold ; scattered brown scales over the wings ; veins narrowly and not prominently lined in brown ; a minute black discal point. Hind wing brownish gray, whitish at base. Expanse, 29 mm. Type, male. No. 21139, U. S. Nat. Mus.; Babaquivera Mountains, Pima County, Arizona (through Dr. William Barnes). 86 INSECUTOR INSCITI^ MENSTRUUS A female, returned to Dr. Barnes, is the same, except that the discal dot is larger and the hind wing nearly white. Platytes acerata, new species. White ; fore wing with the veins narrowly black lined ; broad brown bands in the interspaces, that in interspace 5-6 pale brown ; discal dot round, black ; a row of terminal black dots in the interspaces; an oblique line starting from the costa above discal dot, running out to the fork of veins 8-9 ; fringe faintly interlined with brown. Hind wing distinctly emarginate below apex, white ; veins at apex touched with dusky and a terminal gray line on upper half of wing. Expanse, 15 mm. Type, m^ale, No. 21147, U. S. Nat. Mus. ; Dade City, Florida, September (J. A. Grossbeck). A female before me diflfers in having an irregular broken outer line, brown, strongly excurved over cell and angled on submedian fold. Florida (Schaus collection). Other specimens, apparently referable here, are labeled as follows : One rnale, without abdomen, "From Texas, Boll," "12 VI," "583,"''"I do not know this species. Rag./86, white label 137," "Coll. C. V. Riley," "Chilo densellus, Fernald det.;" a male and female, unset and not fresh, Brownsville, Texas. June, 1904 (H. S. Barber), and a second female, set, with the same collecting data, but further labeled, "Chilo densellus Zell., named by Kearfott, 1908." Platytes densellus Zeller has the veins white-lined, not black- lined. It is curious that this obvious distinction should have escaped two generally accurate authors. Platytes panalope, new species. Fore wing pale straw-color, the veins narrowly lined with dark brown ; fainter and broader brown lines in the interspaces, that in the interspace 5-6 very faint, causing the interspace to appear as a pale ray emanating from the cell; a small black discal dot ; a row of terminal dots between the veins ; an oblique brown line forms an angle on vein 2 at its basal third INSECUTOR INSCITI^ MENSTRUUS 87 and runs thence to the inner margin, faintly shown above across the discal nervules, crossing 3 and 4 and running into the inter- space 4-5. Hind wing whitish on inner half, pale fuscous on costal half. Expanse, 19 mm. Type, male, No. 21140, U. S. Nat. Mus. ; East River, Con- necticut, August, 1907 (C. R. Ely). This species is peculiar in frequently having vein 10 stalked with 8 and 9. The stalking occurs by a fusion of 10 with the stalk beyond the base, so that a small triangular accessory cell is left. This occurs in five out of seven specimens before me. The other two have vein 10 free, although bent toward the stalk. The tongue is practically absent in the male, but quite distinct in the female. Two other species of Platytes with dark-lined veins are known, multilineatella Hulst and punctilineella Barnes & Mc- Dunnough, both from Florida. They are both narrower- winged than panalope, darker and more uniform. In all these species, the hind wings of the female are white or, at least, paler than those of the male. Therefore I think that Hulst described multilineatella from two females instead of two males, as stated, since he describes the hind wings as pure white. Haimbachia venosalis, new species. Fore wing white, the veins broadly lined with chocolate brown, the interspaces with narrow lines of the same color, ending in small terminal black dots ; a distinct black discal spot; fringe interlined. Hind wing white, the veins lined in brown at apex. Expanse, 17 mm. Type, male. No. 21141, U. S. Nat. Mus.; Audubon Park, Louisiana, September 19, 1914 (U. C. Loftin), at light. The female is the same, only a little larger, expanse, 21 mm. The tongue is absent in the male, but distinct in the female, which throws the species out of Diatrcea. It resembles Platytes multilineatella Hulst in a general way, but veins 11 and 12 of fore wing anastomose, compelling the reference to Haimbachia. 88 INSECUTOR INSCITI^ MENSTRUUS SEVEN NEW PYRALIDS FROM BRITISH GUIANA (Lepidoptera, Pyralidcc) By HARRISON G.

DYAR In studying the mosquitoes of the Sierra Nevada Mountains of California in 1916, I was confronted by the problem of a certain similarity between Aedes tahocnsis of the Sierras and A. pullatus of the Rocky Mountain region of British Columbia and Idaho. The two differ in the number of larval head hairs, and it was thought that taho'ensis might extend up the Cascades through the Pacific Northwest to British Columbia, where the mountains meet, and so, the two species converge. Accord- ingly a short exploration was undertaken of the mountains in Washington State in the spring of 1917. Specifically, Glacier, in the Mount Baker region ; Longmire Springs, in the Mount Rainier region, and Lake Cushman, in the Olympics, were visited. Concerning the special problem in hand, it was determined that taho'ensis does not follow up the Cascades, but is replaced by an allied species, and therefore the geographical isolation of taho'hisis and pullatus is assured, together with their dis- tinctness. This is quite clearly indicated by the very different climatic and floral conditions obtaining in the Sierras, as a short stay will readily convince one. In the Northwest it rains, producing a dense forest with moss and undergrowth ; in California there is no rain, the forest being open and dry, while the lowland is treeless. As compared with California, the Pacific Northwest is poor in mosquitoes, both in individuals and in the number of species concerned. But three black-legged species of A'cdcs were found 97 98 INSECUTOR INSCITI^ MENSTRUUS in the mountains instead of six as in California. This is again conditioned by the climate. Frequent rains are conducive to per- manent pools in which A'edes do not thrive. The Culex, Culiseta, and Anopheles that do frequent such places are the same as in California, minus the tropical element, but without any additional species, all resulting in a small mosquito fauna. Aedes aloponotum, new species. Mesonotum light red, with three narrow dark brown lines in the integument; vestiture of narrow curved bronzy brown scales, becoming straw-color about the antescutellar space. Abdomen black, with basal segmental whitish bands, widening at the sides ; venter with median black patches almost forming a band. Wing-scales black, with white ones intermixed on costa and first vein, some also on forks of second and fourth veins. Legs black ; femora white within nearly to tip, a white knee-spot; tarsi with br^d basal whitish rings, the last joint half white. Claws toothed. Type, female. No. 21543, U. S. Nat. Mus. ; Lake Cushman, Washington, June 28, 1917 (H. G. Dyar). Two other females were taken at the same place; one has the integument of the mesonotum dark brown, but with the same foxy-red vestiture. A peculiar species of the cantans group. Male and early stages unknown. Aedes increpitus Dyar. A single female taken at Lake Cushman^. Washington, June 27, 1917, is referred to increpitus pending further information. Aedes curriei Coquillett. A coast species breeding in tidal pools, not distinct from the inland curriei. A specimen was seen on the marsh at Bellingham, Washington, May 31, 1917, and others were cap- tured at Alki Point, Seattle, Washington, June 20, 1917. Aedes cinereus Meigen (fuscus Osten Sacken). A larva was found at Glacier, Washington, and bred to adult, June 13, 1917. Male adults were taken at Lake Cushr man. Tune 26, 1917. INSECUTOR INSCITIAE MENSTRUUS. VOL. V. NOS. 7-9 PLATE M INSECUTOR INSCITI^ MENSTRUUS ' 99 Aedes varipalpus Coquillett. The western tree-hole species occurs both in lowland and the mountains. Specimens have been recorded from Seattle in the monograph and I met with it commonly at Lake Cushman, in the Olympics. A larva was found at Longmire Springs, June 11, in water in a sawed-ofF stump. Aedes aboriginis, new species. Head and mesonotum with dark yellow or brownish yellow narrow curved scales ; a double line of small dark brown ones dorsally ; traces only of the posterior lateral lines ; area around antescutellar space golden. Abdomen black with basal seg- mental narrow white bands, triangularly widened at the sides, narrow posteriorly ; venter grayish white scaled, with traces of a medioventral black stripe. Legs black, femora whitish beneath nearly to tip ; tibicS with a sprinkling of gray scales ; knee-spot white. Wing-scales black, the scaling uniform, fine outstanding scales on the third vein like the rest. In the male, the medioventral stripe of the abdomen is dis- tinct, crossed by apical segmental black bands. Genitalia (See Plate II). Apical lobe of sidepiece small, with slightly curved, partly appressed setae ; basal lobe large, expanded, tubercular, setose, the setae very long and dense on the lower edge, concealing a moderately stout curved spine, not longer than the setae. A thickened area between basal lobe and base, punctured by the insertions of small setae. Stem of harpago moderate, the filament rather short, fusiform, with pointed curved tip. This is essentially as in hexodontus. Larva (See Plate II). Scales of the lateral comb about 20, each with a row of apical spines. Air-tube with the pecten evenly spaced, followed by a 5-haired tuft. Anal segment not ringed by the plate, the plate reaching near the ventral line and evenly margined. Head hairs : Upper in threes, rarely fours ; lower in threes, rarely in twos. Ante-antennal tuft of eight. Types, male and female. No. 21544, U. S. Nat.

G. Dyar). Adult females, Glacier, Washington, June 3, 1917 (H. G. Dyar), and females and males, Lake Cushman, Washington, June 36, 27, 28, 1917 (H. G. Dyar); Hoquiam, Washington, May 27, 1904 (H. E. Burke), the latter erroneously recorded under hexodontus by me (Ins. Insc. Mens., v, 14, 1917) ; old specimens of this, the larger species, Ashford, Washington, August 1, 1906 (Dyar & Caudell). The males were observed swarming at Lake Cushman in small groups in the forest in the forenoon, bright sunlight shining through the trees, but well screened by the dense foliage. The swarms were on the dark side of the trunks of enormous cedar trees, in one case growing upon a rocky bank, which added to the shadow. The swarms were from 6 to 10 feet from the ground, varying from a few to 50 individuals. Aedes altiusculus, new species. Head and mesonotum as in aboriginis, the color a little less yellow, more creamy. Abdomen black, with rather broad basal segmental white bands, triangularly widened on the sides ; venter white, with narrow apical segmental black bands. Wings and legs as in aboriginis. Male with the venter gray-white scaled, narrow apical seg- mental black bands and no trace of medioventral line. Genitalia (See Plate II). Apical lobe of sidepiece large, with long straight sets ; basal lobe expanded, setose, a long stout seta on the outer (dorsal) side. Stem of harpago long, the basal part curved and minutely pilose ; filament sickle- shaped with double dorsal membranous ridge. This is essen- tially as in taho'ensis. Larva (See Plate II). Lateral comb of the eighth segment of about 36 scales, each scale with a row of apical spines. Anal segment not ringed by the plate, which reaches only the middle of the side and terminates in a ragged edge ; lateral hair single. Air-tube with the pecten evenly spaced, followed by a 6-haired tuft. Plead hairs single, long and stout, approxi- mate ; ante-antenal tuft of nine.

Old specimens of this small species, Mount Rainier, Washington, August 3-4, 1906 (Dyar & Caudell). I owe the discovery of this species to Mrs. W. P. Allen, my faithful nurse, and Mr. J. B. Flett, Forest Ranger in the Mount Rainier National Park. Undaunted by the rain and soft snow, these indefatigable people tramped up 1,300 feet of altitude to Indian Henry's, only to find the whole meadow deep in snow. However, they searched for a wet place, and, finding it, scooped out the freezing mixture with their hands. Their perseverance was rewarded by some 20 larvae of altius- culus, in the first stage, which were kicking about in the water under the snow. I would express my obligation to both Mrs. Allen and Mr. Flett for their kindness in making this arduous ascent, which I was prevented from undertaking personally by physical disability. Culiseta impatiens W^alker. This large mosquito is common in all the mountain regions. Adults: Glacier, June 3; Longmire Springs, June 11; Lake Cushman, June 26. Larvae at Lake Cushman in a dark pool in the forest, in considerable numbers, preyed upon by a flock of larvae of Bncorethra. Culiseta incidens Thomson.

Larvae, presumably of this species, were found in woods pools of permanent water. Glacier, Washington, June 2, 1917. An adult was captured at Sumas, Washington, June 2, 1917. 102 INS^CUTOR INSCITI^ MENSTRUUS Anopheles occidentalis Dyar & Knab. Anopheles larvae were common in protected spots around the shores of Lake Whatcomb, Bellingham, Washington, May- Si, 1917. The specimens were not bred, having been acci- dentally left behind on a train in the hurry of making a quick connection, but are presumably of this species. NOTES ON AEDES AT LAKE PEND D'OREILLE, IDAHO {Diptera, Culicidce) By HARRISON G. DYAR A brief stop was made, July 3-4, 1917, at Sandpoint, on Lake Pend d'Oreille, and a trip taken to Sunnyside, an hour's ride down the lake. The altitude is 2,096 feet above sea level. The country is mountainous and well forested with conifers down to the lake margin. The following species of Aides were taken : Aedes aestivalis Dyar. Seventy-three females and twenty-eight males. The meso- notum is whiter than in typical aestivalis from Kaslo, British Columbia, only a few being of the yellow color. This was noticeable to the naked eye, for when the mosquitoes would alight on dark clothing at dusk they looked like little flakes of cotton. Under a lens, most are ash gray with a broad central brown stripe, rarely narrowly divided on mesial line. There is a sprinkling of white scales on the wing along costa and subcostal vein. The genitalia as described in the monograph (vol. iv, p. 742) should be slightly corrected. The basal lobe of the sidepiece is not accompanied by a stout hooked spine, but by a group of stiff setae the outmost of which is thickened and has a large insertion, the spine not being fully differentiated as our de- scription implies. The filament of the harpagone should be described as angularly widened near base. The apical lobe of the sidepiece is sparsely setose, being bare only at the tip on INSECUTOR INSClTlyE MENSTRUUS 103 the under side, which shows only in strongly appressed mounts. The genitalia, therefore, are as in hirsuteron, idaho'ensis, spcncerii, and aldrichi, these species having genitalia of the same type. Indeed, the adults are similar, all having the same coloration of the legs and mesonotal marking, which is subject to variation. In idaho'ensis and spencerii the wing scales are parti-colored as befits a prairie life ; in the other three they are black, as suits the forest. Not improbably these species are re- cently evolved and not fully separated where their localities adjoin. Their general regions are well marked ; aestivalis in the forests of the Rocky Mountains; hirsuteron in the southern Atlantic region ; spencerii in the prairies of Canada ; idaho'ensis in the river prairies of Nevada, Idaho, and Montana ; aldrichi in the river bottoms with idaho'ensis. Aedes idahoensis Theobald. One female. Aedes cinereus Meigen (fusciis Osten Sacken), One male and three females. Aedes canadensis Theobald. Three females. Aedes vexans Meigen {sylvcstris Theobald). Nine males and four females. Aedes sansoni Dyar & Knab. One male and sixteen females. The male is sansoni, as determined by the genitalia ; but abfitchii Felt & Young^ may also occur. At Kaslo, British Columbia, on Kootenai Lake, of essentially the same fauna as this, abfitchii^ was determined. I think both will be found, as lake pools should develop sansoni, while abfitchii^ comes from marshes, for which there is opportunity at Sandpoint. In comparison with the Kaslo list (Proc. Ent, Soc. Wash., vi, 37, 1904), the following A'edes were there noted : Aedes pullatus Coquillett (as impiger Walker). A'edes abfitchii Felt & Young' (as cantons Meigen). 'This should be called A. mimesis Dyar. See my remarks under this heading in a paper on the A'edes of Montana, which follows. 104 INSECUTOR INSCITI^ MENSTRUUS A'edes aestivalis Dyar (as reptans Meigen). A'edes canadensis Theobald. A'edes trichurus Dyar (as punctor Kirby). A'edes vexans Meigen (as sylvestris Theobald). A'edes varipalpus Coquillett. A'edes curriei Coquillett. A'edes spencerii Theobald. A'edes cinereus Meigen (as fuscus Osten Sacken). The smaller number of species at Lake Pend d'Oreille is partly accounted for by the brief time devoted to collecting, the early forms, pullatus and trichurus, having probably dis- appeared. A. curriei and spencerii are strays at Kaslo, as is idahoensis at Sandpoint. The tree-hole species, varipalpus, may be locally present at Lake Pend d'Oreille. Aside from these, the lists are identical. NOTES ON THE AEDES OF MONTANA {Dipt era, Culicidce) By HARRISON G. DYAR A brief report on the mosquitoes of Montana is given in the Fourteenth Annual Report of the State Entomologist of Mon- tana, December, 1916, by J. R. Parker, He lists (omitting Culex, Culiseta and Anopheles) : A'edes curriei Coquillett, the most abundant species. A'edes sylvestris Theobald, the next in abundance. A'edes nigromaculis Ludlow, the third in abundance. A'edes spencerii Theobald, the fourth in abundance. A'edes pullatus Coquillett, in timber at high altitudes. NOT COMMON A'edes campestris Dyar & Knab. Aedes flctcheri Coquillett. A'edes stimulans Walker (group). A'edes idahoensis Theobald. Aedes hirsuteron Theobald. A'edes fuscus Osten Sacken. A cursory passage of the State reveals certain additional information, which is here noted. INSECUTOR INSCITI^ MENSTRUUS 105 The writer passed tlirough Montana by the Northern Pacific Railroad, and made a few stops for collecting. The course of the railroad is as follows : Entering Montana on the west from the northern spur of Idaho, it follows up Clark's Fork of the Columbia River, passing beyond the entry of the Flat- head River, and crosses the divide of the Mission Range at (1) Evaro, (3,971 feet) ; proceeding downward by a sharp grade into the valley of the Hell Gate River, (2) Missoula (3,323 feet) is reached; the road then follows up the valley of that stream to (3) Drummond (3,967 feet) ; a tributary of this same stream is followed practically to its source, whence the road rises sharply and crosses the Continental Divide at (4) Homestake (6,356 feet) ; it then descends into the valley of the Missouri River, passing (5) Whitehall (4,371 feet) ; thence it ascends a tributary of the Missouri, the Gallatin River, nearly to its source, passing (6) Bozeman (4,773 feet), well up in the narrower part of the Gallatin Valley; a low divide is crossed through the Gallatin Range and the road descends into the valley of the Yellowstone River, passing (7) Big Timber (4,094 feet) and (8) Laurel (3,311 feet). No stops were made after Laurel, the road following the same valley as it widens into the plains, almost to the eastern border of Montana. Unfortunately, no stop was feasible at Homestake (4), so nearly all the collections are from river valleys. The wooded mountains should yield other species, such as Aedes pullatus and trichurus as at Kaslo, British Columbia, and Aedes aesti- valis, as at Sandpoint, Idaho. This forested mountain region connects along the Coeur d'Alene-Bitterroot chain with the main Rocky Mountains, and the mosquitoes mentioned not improbably follow into western Montana. Indeed, Parker lists two of them, namely, pullatus and hirsuteron (==aesti- valis). Disregarding the high forested regions and the sparsely wooded mesas and hills, and referring only to the river valleys, the following conditions appear : Mosquitoes are naturally abundant and certain species have been evidently much in- creased in numbers by artificial conditions. Five species were 106 INSECUTOR INvSClTl^ MENSTRUUS observed to be able to take advantage of these, by breeding successfully in pools produced by irrigation. While originally these forms were doubtless confined to a single annual genera- tion following the spring snows, now they breed as often as the obliging farmers furnish suitable pools. These species are : A'edes curriei, nigromaculis, vexans, trivittatus and another referred to under spencerii below. The river valleys furnish two faunal areas, one the river bottom itself, wooded, often densely clothed with cottonwood and willow; the other the high flood-plain, destitute of trees and resembling a prairie. Characteristic of the latter region are A'edes curriei, nigromaculis, and idaho'ensis. A. vexans also invades it, though commoner in the river bottom. The habits of trivittatus are probably similar to those of vexans, although being a rarer species, specimens were captured only by the river, though bred from prairie pools. The males of curriei, nigromaculis, and idaho'ensis swarm on the prairie; vexans only by the river ; the swarming of trivittatus was not observed. Exclusively river-bottom species are : A'edes aldrichi, cine- reus, and satisoni. A'edes campestris and fletcheri, listed by Parker, were not taken by me. Parker does not indicate the localities where he found them. Both are prairie species. THE L0C.\UTIES (]) Evaro, 3,971 feet. In spite of the comparatively low elevation, this has much the character of a mountain meadow, a typical breeding place for the early snow-water species. A flat marshy area, draining in both directions, is surrounded by hills clothed with pine forest. When visited, the season was far advanced ; not only had all breeding of the early species ceased, to be replaced by larvse of Culex and Cvdiseta, but the mosquitoes themselves were nearly gone. Only seven speci- mens were found in a day's collection, though earlier they must have been numerous, as was stated to have been the case by the station agent. A'edes idaho'ensis Theobald. One female. A'edes sansoni Dyar & Knab. Two females. Not certainly INSECUTOR INSCITI^ MENSTRUUS 107 determinable by the adults alone. I would have expected mimesis, which occurs at Kaslo, British Columbia, to the north- ward of this region, and the character of the breeding ground — marshes — indicates this species rather than the river-pool sansoni; but the wing scales are as in sansoni. A'cdes pullatus Coquillett. Two females. A large species of the black-legged group, the mesonotum clothed with dark brown scales without dark bands, the wing-scales black. This does not agree well with pullatus, but in the absence of full data I do not venture to separate it. Aedes aestivalis Dyar. Two females. A smaller species of the black-legged group with gray lateral vestiture on the mesonotum. Both specimens are worn and in too poor shape for exact determination ; but as aestivalis abounds at Sand- point, Idaho, in a not wholly dissimilar region, the determina- tion is made tentatively. (2) Missoula, 3,233 feet. Situated in the broad prairie flood-plain of the Hell Gate River at the junction of two forks. The plain is surrounded by high hills, mostly bare of trees on their aspect toward the town, but wooded on the northern slopes toward the river canyon. Aedes idahoensis Theobald. Eighty-seven males and fifty- three females. Of the latter 20 are atypical, having the black and white scales on the wings not contrasting, though some are at least pale, and so transitional toward aldrichi Dyar & Knab. Aedes vexans Meigen (sylvestris Theobald). Eight males and fifty-seven females. Aedes sansoni Dyar & Knab. Twenty- four males and forty- seven females. Aedes cinereus Meigen (fusctis Osten Sacken). Five females. Aedes triseriatus Say. One female. Aedes sp. One female with black legs and black wing- scales, possibly a specimen of pullatus strayed from the for- ested hills above. The specimen is badly rubbed. It was taken in Reno Park in the well-forested river bottom. 108 INSECUTOR INSClTl^e MENSTRUUS A pool was found by the river, filled by waste water coming through the railroad track, which contained many pupse and a few larvae of sansoni, vexans, and cinereus. (3) Drummond, 3,967 feet. Though practically of the same altitude as Evaro (1), this place has the characteristics of a river-valley locality. There is a broad flood-plain without trees where the town is situated. A short walk brings one to the river, which has many overflow pools and channels, for the most part lined with low willow bushes. One day's collect- ing was spent here, entirely in the river bottom. A'edes spencerii Theobald. Three females. A'edes idaho'ensis Theobald. One male, 68 females. Of the latter, 3 transitional toward aldrichi and one toward spencerii. A'edes vexans Meigen. One male and 50 females. A'edes sansoni Dyar & Knab. One male and 100 females. A'edes mimesis Dyar. Two males and 25 females. A'edes cinereus Meigen. Eighty-nine females. A'edes canadensis Theobald. Thirty-one females. A'edes curriei Coquillett. Eighteen females. A'edes sp. One female with black legs, too much rubbed for determination. (4) Homestake, 6,356 feet. On the crest of the divide The mountain slopes to the west both steep and dry; but on the east the descent is more gradual and there is opportunity for breeding pools. Interesting species should occur. (5) Whitehall, 4,371 feet. Of the same general character as Drummond (3). The flood-plain is well marked and tree- less, the river bottom clothed with low willow bushes. Collec- tions were made both on the prairie and river bottom. A'edes idaho'ensis Theobald. Ten males and 110 females. Of the latter three intermediate toward aldrichi and six toward spencerii. A'edes vexans Meigen. Four males and 83 females. A'edes sansoni Dyar & Knab. Nine females. A'edes mimesis Dyar. Four females. A'edes cinereus Meigen. Two females. A'edes curriei Coquillett. Forty-six females. A'edes nigromaculis Ludlow. Thirty-six females. INSECUTOR INSCITl/lt MENSTRUUS 109 (6) Bozeman, 4,773 feet. This is situated toward the head of a valley. The prairie is undulating, while the river is small. A considerable area of valley is covered with dense bushes of Crataegus and dwarf poplar. A'cdes idahoensis Theobald. Twenty males and 59 females, the latter all typical. A'cdes vexans Meigen. One female. A'cdes sansoni Dyar & Knab. One hundred and eighty females. A'cdes mimesis Dyar. Four females. A'cdes cinereus Meigen. Four females. A'edes canadensis Theobald. Ten females. A'cdes nigromaculis Ludlow. One female, small and lightly colored. (7) Big Timber, 4,094 feet. The town is on the edge of the prairie, whence one descends a rather steep hill to the river bottom. This latter is wide, with many dead channels and marshes, covered with willow bushes and groups of tall cottonwoods. From the latter the place gets its name. Col- lecting was done both on the prairie and in the river bottom. A'cdes idahoensis Theobald. Ninety-eight females, of which 6 intergrade toward aldrichi. A'cdes aldrichi Dyar & Knab. Twelve males and 184 females. A'cdes vexans Meigen. Seventy-four females. A'cdes sansoni Dyar & Knab. Three females. A'edes cinereus Meigen. Three females. A'edes curriei Coquillett. Eight females. A'cdes nigromaculis Ludlow. Thirty-one females. (8) Laurel, 3,311 feet. Farther down the Yellowstone Valley than Big Timber, the conditions intensified. The prairie is wide, the town situated a mile and a half from the river, while it is an equal distance to the sparsely pine-clad bluffs that border the valley. Irrigation is much resorted to. The river is large, with steep bank on one side, but low on the other, the bed enclosing low islands and forming marshes and dead channels. Collecting was done on both prairie and river bottom. 110 INSECUTOR INSCITI^ MEINSTRUUS Aedes idahoensis Theobald. Twenty-three males and 19 females. Aedes aldrichi Dyar & Knab. Sixty females. Aedes vexans Meigen. One hundred and fifty-six females. Aedes cinereus Meigen. Five females. Aedes curriei Coquillett. Forty-two males and 654 females. Aedes nigromaculis Ludlow. Thirty-eight males and 726 females. Aedes sansoni Dyar & Knab. One female. Aedes trivittatUrS Coquillett. Thirty-eight females. Aedes sp. One female. A black-legged species of large size, too much worn to identify. Psorophora signipennis Coquillett. Three females. A number of pools formed by seepage from irrigation ditches on the prairie contained larvae and pupae of Aedes curriei, vexans, nigromaculis, and trivittatus, of which 124 specimens were bred. The above collections show relative abundance as follows: A. nigromaculis first with 832 specimens, curriei second with 768 specimens, idahoensis third with 550 specimens, and vexans fourth with 434 specimens. It almost seems as if Mr. Parker must have accidentally transposed the labels on his determined idahoensis and spencerii, for I got only two of the latter, while the former was one of the common species. Except for this discrepancy, I find the same species abundant as does Parker. The relatively different order is largely accidental. In a gen- eral way, curriei is the most widespread and abundant species. My collections were influenced by a local abundance of nigro- maculis at Laurel. Similarly, idahoensis is more abundant in western than in eastern Montana, and my collections plainly have a larger western proportion than Parker's, as I did not collect east of Laurel, which is near the middle of the State. THR SPECIES Aedes curriei Coquillett. A widespread species, especially on the prairie. The colora- tion varies greatly. The males swarm over bushes or promi- nent objects. At Laurel, on the prairie, just at sunset, a INSECUTOR INSCITI^ MENSTRUUS 111 rapid swarm was observed in a low bush about three feet from the ground. It was netted and proved to be curriei. Half an hour later, when it was getting too dark to see distinctly, an- other group of males was seen in a taller bush (Sarcobatus vermicidatus) , circulating among and over the top branches. They did not swarm over the writer's head, although some idahocnsis were doing so at the time, and as I approached the bush the two swarms became slightly mixed, though the idaho- cnsis were higher. Next evening I visited the same bush and observed two swarms over it. One was over the top of the bush and proved to be idahoensis , the other a little to one side and below the top, on the lee side, was curriei. Also the same evening, in the open, a swarm gathered over my head, partly mixed with nigromaculis. In netting mosquitoes to avoid their bites one night in walking from the river to the town at Laurel, of about 600 specimens so caught three were males of curriei. They had evidently been swarming over my head. As determined by Knab, the larvae appear in the early snow pools on the prairie. In the presence of irrigation, however, other broods appear, probably every time favorable pools are formed. I establish the fact that eggs will hatch the same year as laid. At Reno, Nevada, I got curriei eggs from cap- tive females, allowed them to dry, then added water in about ten days and a part of the eggs hatched. The water was poured off and the procedure repeated, when more :eggs hatched. There is thus seen to be no physiological difference between curriei, the inland form, and quaylei of the Pacific coast, as was supposed. Both hatch whenever they get water. The larvse of curriei (Laurel, Montana) have the head hairs single like quaylei of the coast, and onondagensis of New York. The comb scales are evenly fringed with long spines, quite as in quaylei. In onondagensis there is a slight differ- entiation of the central spine, but not on all the scales. Curriei from Reno, Nevada, have single head hairs and a slight dif- ferentiation of the central spine of the comb scale. Aedes campestris Dyar & Knab. Recorded by Parker, the determination by Knab. This is 112 INSECUTOR INSCITI^ MENSTRUUS very close to curriei, differing principally in being slightly larger. There may be a few specimens among my 768 curriei, but I have not detected them and more probably campestris inhabits a different area from that traversed by me. The two specimens differ in the male genitalia. Not as radically as given in the monograph, which should be cor- rected on this point, but sufficiently. In curriei, the basal lobe of the sidepiece has two spines, a large curved one centrally and a shorter straight one at the margin. In campestris the middle spine is straight and about as stout as the outer one in curriei, while the outer one is absent, being represented by two stout setae. This is an unexpected divergence, since the two spines are present and of the same structure in curriei, quaylei, onondagensis, and even the European dorsalis Meigen, though somewhat approximate in the latter. In campestris, however, the type is altered. Aedes canadensis Theobald. Not found in the plains and in the river valleys only near the mountains. The species is characteristic of the northern At- lantic coast region, extending even to Florida. It ranges westward through Canada to the Rocky Mountains. The species is not recorded by Parker. Aedes nigromaculis Ludlow. This species is characteristic of the prairie section of the river valleys. It never comes into the timbered country. I did not encounter it west of the Great Divide. The males form a loose active swarm above prominent objects on the prairie. On the evening of July 15, at Laurel, they gathered above the writer's head, rising to a great height when disturbed, gradually settling to two or three feet above the head. After half an hour the swarm became partly con- fused with a swarm of curriei, which gathered in a similar position, but lower. Another visit to the Sarcobatus bush men- tioned above, after sunset, showed three swarms of males, nigromaculis above the bush high up, idaho'ensis above but lower, and curriei low and a little to one side. INSECUTOR INSCITI^ MENSTRUUS 113 The egg is long, slender, spindle-shaped, a little flattened on one side, shining black, laid singly. Eggs deposited about July 20 were allowed to dry and water was added on August 2. The larvae hatched in consid- erable numbers within 15 minutes after the addition of the water. The habit is the same as with curriei and trivittatus, part of the eggs hatching whenever submerged, and over- wintering is not necessary for emergence. Consequently the larvae occur in irrigation pools, frequently in large numbers. The larva (see Plate II) has the tuft of the tube far out, beyond the pecten which runs nearly to the end of the short tube ; pecten with detached teeth outwardly ; anal segment ringed by the plate; comb-scales seven to ten, in a patch, not in a line, the single scale with long sharp cen- tral spine and fringe of a few slender ones at base ; head hairs both single, ante-antennal tuft in fours. Aedes fletcheri Coquillett. Superficially similar to nigromaculis, replacing it on the prairies of Saskatchewan and Alberta. The coloration is the same, but more yellowish in fletcheri, paler and suflfused. There is no white ring on the proboscis, but this is also some- times absent in nigromaculis. The species enters Montana at the northern part, as our single record proves. Big Fork, Flat- head County, 1904 (E. M. Ricker). Mr. Parker's specimen seems not to have been preserved in the collection. I did not meet with the species. Aedes riparius Dyar & Knab. A single specimen, Dillon, Montana, August 4, 1908 (R. A. Cooley), in the collection of the National Museum, agrees with this species. It is close to fletcheri in coloration, but differs in the abdomen, which in riparitis is lightly suffused with whitish scales, in fletcheri strongly so. However, they differ in habit, fletcheri being a prairie species, while riparius frequents the timber along the river bottoms. I did not meet with this species. Dillon is in the Beaver Head valley, a tributary of the Missouri. The species ought, perhaps, to have been en- 114 INSECUTOR INSCITI^ MENSTRUUS countered by me at Whitehall, unless it frequents high timber, of which there was none at that place. Aedes sansoni Dyar & Knab. The types of sansoni are five specimens, numbered, respec- tively, 10, 13, 14, 17, and 20 by the collector. Nos. 10, 13, and M are females, 17 and 20 are males. No, 20 is Aedes curriei, as shown by the genitalia. No. 17 has lost the abdomen, but has the sides of the mesonotum very white, as is also the case in the females, Nos. 13 and 14. No. 10 has the usual mixture of brown and white, the brown predominating, and may be selected as the type. The wings show a sprinkling of white scales along costa and subcostal vein. A. sansoni was described from Banff, Alberta, a locality on a river flowing from the Rocky Mountains. In the monograph, we added certain other specimens, namely: Larva from Kaslo, British Columbia; a male from Juliaetta, Idaho; male and females from Eureka, California, and females from Fieldbrook, California. I have lately removed the California specimens to increpitus Dyar (Ins. Insc. Mens., V, 15, 1917). I now propose to remove the Kaslo larvae. The larvae agree with ahfitchii essentially, and will be found re- ferred to under the heading mimesis below. This will define satusoni as the river-pool species of the Rocky Mountain streams, and definitely associate the Banff female with the male from Juliaetta, Idaho. Males from Missoula, Montana, agree. Larvae from Missoula are of the typical river-pool form (see Plate II), indistinguishable from stiinulans Walker of the east or increpitus Dyar of California. The three species separate on male genitalia : Basal lobe of sidepiece weak, tuberculate, sparsely setose, accompanied by a very strong spine stimulans Walker Basal lobe of sidepiece tuberculate and diffused, without a strong spine. Filament of harpago slenderly sickle-shaped, expanded at basal third (see Plate II) sansoni Dyar & Knab Filament of harpago with angular expansion beyond middle. increpitus Dyar A. sansoni was common in all the wooded river bottoms. INSECUTOR INSCITI^ MENSTRUUS 115 although, by the time I reached Laurel, they had become scarce and worn. The egg is elliptical, rather thickly fusiform, a little flattened on one side, large, shining black, laid singly. Eggs obtained about July 15, 1917, though repeatedly wet, failed to hatch and appear destined to hibernate. Grabhamia vittata was described by Theobald from Pecos Canyon, New Mexico, the description being indeterminate and applying to any species of the cantans group. Mr. Theobald had males and larvae, but the genitalia were not described and the larvse were wrongly associated, being those of Culiseta incidens Thomson. The species therefore rests solely on the locality. This is in the Rocky Mountain range and therefore we probably have to do with the species of that region. There are but two of the cantans group known from the region and probably but two occur, judging from the analogy of Cali- fornia, where we have two, increpitus Dyar in the river pools and palustris Dyar in the marshes. I have identified the river pool species as sansoni Dyar & Knab ; but the name vittata remains indeterminate. The foregoing was written under the assumption that the two Rocky Mountain forms of the cantans group were indis- tinguishable in the female adult. While the manuscript was in the printer's hands, I have gone over the matter more care- fully. In California, palustris is distinguishable from increp- itus by the excess of white scales on the wings. It occurred to me that the same might be true of mimesis as compared with sansoni. A careful examination of females showed that two series could be separated on this character. The distinc- tion is not as marked as in the Californian forms, but it is there. On this basis, I re-examined the three females of vittata Theobald which are before me from the lot that fur- nished Theobald's types, and they are all sansoni. But whether a restriction of vittata be made or not, the name becomes a homonym and must be dropped. Bigot described Culex vittatus in 1861, which is considered a synonym of A'edes sugens Wiedemann. Therefore the name vittatus or vittata cannot be used again in the genus. 116 INSECUTOR INSCITI^ MENSTRUUS Aedes mimesis, new species. I propose the name mimesis for the unnamed form, since both sansoni and vittata apply to the river-pool species, the type being the male from Drtimmond, Montana, mentioned below. The type number is 31553, U. S. Nat. Mus. The larva of mimesis will be the larva from Kaslo, British Columbia, which so closely resembles that of abfitchv'. As to the genitalia, I have a specimen from Drummond, Montana, which differs distinctly from sansoni and comes very close to palustris of California. This is entirely as it should be, sansoni of the Rockies representing increpitus of the Sierras, while mimesis of the Rockies represents palustris of the Sierras. The genitalia runs as follows : Basal lobe of sidepiece conical, setose, with a stout seta on the inner angle, but without a strong spine. Filament of harpago small, sickle-shaped. Spines of basal appendages long palustris Dyar Spines of basal appendages moderate mimesis Dyar The habitat of mimesis appears to be more restricted than that of sansoni. I encountered the species only at Drummond, Whitehall, and Bozeman ; a small series from Aweme, Mani- toba (June 13-July 10, 1910, N. Criddle), are all mimesis; no sansoni being present. Psorophora signipennis Coquillett. Three specimens. Laurel, Montana, July 15, 1917, biting after sunset on the prairie. Previous records of this species are from Mexico, Texas, and New Mexico. The present record extends the known range considerably. Aedes vexans Meigen {sylvestris Theobald). Males were observed swarming after sunset at Big Timber in the river bottom, in little open glades under willows and on the dark side of bushes. The species is abundant, flying both on the prairie and river bottom, though much more abundant in the latter location. Larvae were found breeding in temporary irrigation pools. Hatching experiments were not conducted with this species, but the inference is that part of the eggs will hatch INSUCUTOR INSCITI^ MENSTRUUS 117 whenever wet, whether of the same season's deposition or of the previous season's. This is the case with curriei, nigroma- culis, and trivittatus, the three other species inhahiting the irrigation pools with vexans. Aedes trivittatus Coquillett. Found only at Laurel and probably confined to the eastern half of Montana. The adults frequent the river bottom by preference, though they must at least make excursions into the prairie, as larvae occurred in temporary irrigation pools a mile and a half from the river. The species is rare and can- not be considered as especially troublesome. The tgg is thickly fusiform, pointed at the ends, a little flattened on one side, rather large, shining black, laid singly. Eggs deposited July 25, 1917, were submerged a few days later and larvae immediately hatched, but leaving many un- hatched eggs in the water. The habit is the same as in curriei, that part of the eggs hatch whenever submerged and that the cold of overwintering is not a necessary prerequisite to hatching. Aedes cinereus Meigen. {fiiscus Osten Sacken). This species is confined to the river bottoms and vicinity in the arid country. The little mosquito is a bad biter in the timber and low willows. Males were seen swarming after sunset at Laurel in the river bottom between arched willows about seven feet from the ground. Also males were netted in willows at Lake Cushman, Washington. In the latter case the swarming could not be witnessed, but was undoubtedly taking place. No specimens were seen on the prairie, nor were larvae bred from temporary irrigation pools in the open. At Missoula an artificial pool under willows was inhabited by the larVvTS. In New Hampshire I bred the species from roadside pools following rain, together with vexans and canadensis. These three species will, therefore, breed in accidental pools all summer, but only vexans takes advantage of irrigation pools in the open, the other two species being confined to forested countrv. 118 INSECUTOR INSCITI^ MENSTRUUS Aedes triseriatus Say. A single female was taken at Missoula. This is the eastern tree-hole species and was hardly to have been expected in the Rocky Mountain region. At Kaslo, British Columbia, on Kootenai Lake, A. varipalpus was the tree-hole inhabiting form. This is not listed by Parker. Aedes pullatus Coquillett. This name is used in a general sense to cover the black- legged species of high altitudes. The true pullatus doubtless occurs, as we have it from Juliaetta, Idaho, but other similar species have been confused. Solitary rubbed specimens re- ferable to the group were taken here and there, but without males or larvae certain determination cannot be made. These species fly in May, and, at the time of my visit, had mainly disappeared. Aedes prodotes, new species. Mesonotum gray at the sides, a dark brown shade over the disk ; in this two narrow lines of small dark brown scales ; short lateral stripes posteriorly ; area of antescutellar space light gray. Abdomen black with basal segmental white bands ; venter whitish scaled with medioventral black stripe, crossed by apical segemental black bands. Legs black ; femora white below nearly to tip ; knee-spot white ; tibiae with a few gray scales. Wing scales black. Palpi, antennse, and proboscis black. Genitalia (see Plate II). — Sidepiece with a well-developed apical lobe ; basal lobe conical, setose, with an accompanying single spine ; harpago long, slender, curved, uniform ; filament long, angularly expanded on one side at base, then tapering to a curved point. Type, male, No. 21546, U. S. Nat. Mus. ; Bozeman, Mon- tana, May 7, 1907 (R. A. Cooley) ; another male is the same, Banff, Alberta, 1908 (N. B. Sanson), but the vestiture of the mesonotum is indistinct. The female adult is apparently indistinguishable from pullatus or tahocnsis The male genitalia are similar to lazar- t'Hsis, but differ slightly in the shape of the filament of the inse;cutor insciti.^ menstruus 119 harpago. The coloration of the mesonotum makes an asso- ciation with lazarensis impossible. Aedes aestivalis Dyar. Two rubbed females from Evaro (1) are tentatively referred here. The species is abundant in northern Idaho and has been discussed on a previous page. Several specimens from Drummond, listed under aldrichi, come very close to aestivalis, and, taken alone, would easily be so determined. I think, considering the circumstances, that they are aberrations of aldrichi. Aedes spencerii Theobald. Only three specimens were captured among numerous idaho- ensis. A. spencerii is dominant on the prairies of Saskatche- wan, as shown by Knab, and is represented in southern Mon- tana by idaho'ensis. Quite possibly the species intergrade on middle ground. The occurrence of so few spencerii in this region suggests that it may be here an aberrational form of idaho'ensis, becoming dominant in the north. A. spencerii, as found in Saskatchewan, is a medium-sized species, the wing-veins bicolored, the abdomen with a dorsal whitish stripe, often much suffused with white, occasionally the dorsal stripe more or less completely absent; mesonotum gray or yellowish gray, anterior angles brown, dorsal brown stripes usually completely conjoined into a band and touching the short posterior stripes ; occasionally the dorsum is suf- fused with a brown shade. Legs with white scales, often numerous, the tibiae largely white-scaled above. The three specimens referable here, from Drummond (July 10), are all of the gray form, old and worn. Two fresh specimens of the yellow form were bred from pupae in irriga- tion pools at Laurel, July 17-18. No adults were seen flying at this place. The larva was not obtained, nor has a larva corresponding to that of spencerii been taken in Montana. Mr. Parker sent two larvse on slides. Laurel, August 35, 1914 (R. W. Wells), and Harlem, May 28, 1915 (R. A. Cooley), which do not coincide with any known species (see Plate II). 120 INSECUTOR INSCITI^ MENSTRUUS Head hairs single; air-tube with 17 teeth, the last two or three de- tached, the tuft arising beyond; lateral comb of eighth segment of 21 scales, each with a large central spine; anal segment not ringed by the plate, which runs close to the ventral line. If the larva of spencerii were unknown, I should be in- clined to assign this larva to it. As it is, further investiga- tions must be made. I do not think the larva can be idaho- ensis, which should be closer to spencerii than this is. There is thus a fifth species, whether spencerii or not cannot yet be said with certainty, breeding in irrigation water after the dis- appearance of the early spring brood, but in negligible numbers. Aedes idahoensis Theobald. Very common on the limited prairie surrounded by mountains, especially in western Montana. At Laurel females were scarce, though males were still swarming, and the species seemed to be disappearing. It was rare at Sandpoint, Idaho, in forested country. All the specimens taken in western Mon- tana have the abdomen with basal bands only. At Drummond a few spencerii-\ike forms were taken, as noted above. Farther east the typical form obtained again. At Bozeman the males were observed swarming. I went out toward the prairie at sunset, and, as the sun set, males w re seen in a swarm over my head. The group would aug- ment in number, then diminish, keeping about a foot overhead, all the individuals facing toward a light breeze which blew from the south. Two boys, perched on top of a water tank, called out that there were mosquitoes up there, but they were not bitten. The tank was at least 25 feet from the ground. At the same time females were attempting to bite in the grass about ankles and knees. At Laurel the males were repeatedly seen swarming over low isolated bushes {Sarcobatus vermicu- latus) in company with nigromaculis and currici, but always in separate swarms, each with its own relation to the bush. The species exhibits a certain variability. The intergrada- tion toward spencerii in the Missouri valley has been noted. The species also intergrades toward aldrichi at the timber in the river vallevs, which it invades to some extent. INSECUTOR INSCITI^ MENSTRUUS 121 Eg'gs obtained from captive females are long, slenderly spindle-shaped, shining black, laid singly. Aedes aldrichi Dyar & Knab. This is the smallest Aedes known to me. While varying in size, as all mosquitoes do, the average is small and often minute. When biting, and the proboscis is driven far down, the little insect tips up behind and sometimes loses hold with all its legs, suspended by the proboscis. The species inhabits the river bottoms strictly, never straying far from the edge of the timber. It is a close ally of idaho'ensis, but smaller, the wing-scales all dark. The mesonotum has the two dorsal brown lines narrow and separated, the anterior angles gray. Certain intergrades occur, as noted above, but not in the typical dense forested areas. A mount was prepared from a male taken in the timber with numerous females of typical aldrichi, at Big Timber, July 13, 1917. The genitalia (see Plate II) have the apical lobe of the sidepiece well rounded off and bulbous, continued narrowly basally, but not reaching basal lobe, clothed with small, sparse, nearly straight setse; basal lobe expanded, tubercular, a mod- erately stout spine arising from the inner (ventral) margin, without long setae, the setae on the inner margin of the lobe becoming dense, but not much longer than elsewhere ; filament of harpago angularly expanded near the middle. The genitalia are, therefore, much as in idaho'ensis and spencerii, differing in the reduction of long setse which accom- pany the spine of the basal lobe in those species. 122 INSECUTOR INSCITI^ MENSTRUUS NOTES ON AEDES CURRIEI (COQUILLETT) {Diptera, Culicidce) By HARRISON G. DYAR and FREDERICK KNAB This peculiar mosquito was first made known in North America from the plains of North Dakota, under the name Culex curriei Coquillett. In coloration it essentially resembles A'edes dorsalis (Meigen) of Europe, and it is doubtful if Coquillett would ever have separated it therefrom except that, through an error, he was led to believe that the claws of the female were simple in one case and toothed in the other. The error was subsequently corrected, but the species was left to stand on account of what had been discovered in the meantime. This was that mosquitoes of the same general habitus bred in the tidal pools on the coast of California and others were found in central New York State in the general vicinity of the salt wells, while it was to be assumed that those from the western plains bred in temporary pools of fresh water. Here was an obvious difiference in habit, indicating apparently three species, one on the great western plains, one on the California coast, and a third in the Atlantic region. These forms re- ceived names as species, the Californian one being called quaylei by Dyar & Knab from the larvse and lativittatus by Coquillett on the adults. Those from New York were named ononda- gensis by Dr. E. P. Felt. To add to the apparent difference of these forms, Knab discovered the larvae of the inland curriei in Saskatchewan and found marked differences in the num- ber of head hairs and in the distinctness of the central spine of the lateral comb scales. The larvae of the Pacific and Atlantic forms proved to be much alike. In the monograph^ we rely mainly on the larva in our separation of the forms, classing quaylei as a race of onondagensis and holding them distinct from curriei on this and on habits, curriei appearing to have but a single spring generation in the water following the melt- ing snow, while quaylei bred monthly in the high tide pools along the coast. Of the habits of onondagensis we knew 'Howard, Dyar & Knab, The Mosquitoes of North and Central America and the West Indies, iv. fi29-6,S8. 1917. INSECUTOR INSCITI^ MENSTRUUS 123 nothing, but imagined vaguely that they must in some way resemble those of quaylei. Of course, with two species and a race in America, the European dorsalis did not concern us much, as it was quite presumably distinct. While the monograph was still in press, in 1916, the senior author obtained eggs from captive females in Nevada, a typically inland place and therefore certainly curriei. He wet the eggs after first drying them, and, contrary to expectation, the larvae immediately hatched. To add to this heretical be- havior, for, being curriei with supposedly but a single annual generation, they should not have hatched until after being subjected to the cold of a northern winter, the head hairs were single and the comb scales without a distinct central spine, thus agreeing with quaylei or onondagensis. It still appeared possible that there were two species mixed up under curriei and that one of them was perhaps to be considered medio- lineata Ludlow, which was referred in the monograph as a melanotic form of curriei. However, no change was intro- duced in the monograph, which was published immediately. The following year the senior author continued his investiga- tions, this time in Montana, where he found that the curriei larvse were of the same form as in Nevada, and, moreover, had the habit of breeding in irrigation pools at intervals all through the summer. The supposed difference in habit be- tween the coast form and the inland form no longer existed, since eggs of either hatched whenever they were wet, whether the water were salt tidal water, or spring rains, or melting snow, or accidental irrigation pools. Moreover, the larval differences had likewise disappeared, and the question had come around to the correctness of the junior author's observa- tions in Saskatchewan. The material was, therefore, carefully gone over and it was found that, while there were plenty of true curriei, the particular skins which had been mounted and studied as curriei for all these years were nothing but cana- densis. The true curriei from Saskatchewan have single head- hairs and the scales of the lateral comb without strong central spine exactly as in Nevada and Montana. This unfortunate mistake created a complicated viewpoint and has led to a 124 INSECUTOR INSCITI.5; MENSTRUUS great deal of trouble ; but we are now able to solve the mystery and correct the synonymy of this species. In the monograph (pp. 618. 631, 634, and 637) we give differences in the male genitalia, stating that in curriei and onondagensis the stem of the harpago is slender, but stout in quay lei. It does so appear in the old slides of quaylei, one from Oakland, California, June 34, 1903 (I. McCracken). another from Tacoma, Washington, August, 1906 (Dyar & Caudell) ; but these have been strongly pressed. In a fresh preparation from Atherton, San Mateo County, California (L. Mc- Roberts), which has not been pressed, the difference is not appreciable. The two pressed slides were prepared by Mr. H. S. Barber, while all the rest, except one onondagensis, which was prepared by Mr. O. A. Johannsen, were made by the junior author. The supposed specific character of quaylei is therefore due to the method of preparation. There is some variation in the comb-scales of the larva, which might mislead the inexperienced. The free margin of the scale is drawn out into a series of teeth, those at the tip longest. Usually there are a number of subequal teeth at the tip ; however, sometimes there is a distinctly longer one in the middle, but without structural difference. In the type that we define as having a "differentiated median tooth," the tip of the scale is drawn out to a long spine, while on each side there is a marginal row of cilia. In all the larvse of curriei we have ex- amined, rows of minute spicules are present on the skin. They vary considerably in abundance and can only be detected under high magnification. Acdes curriei thus constitutes but a single species ranging over most of the United States. The other names cited are based upon illusory differences and will become synonyms. The stronghold" of the species is in the western plains and the desert country of Utah, Nevada, and eastern California ; but it penetrates to all the coasts, having been taken on the coast of New England and on the Gulf of Mexico. It has been taken near Chicago, and is probably scattered through open country here and there, finding a local abundance in favorably situated tidal pools. It does not occur in forested country, which INSECUTOR INSCITI^ MENSTRUUS 185 explains its rareness in the East. Salt marsh pools, it may be noted, are not forested and hence the occasional occurrence of the species on the Atlantic seaboard. The species has as many generations in the year as the conditions warrant, al- though probably only part of the eggs hatch at each successive wetting. Dyar demonstrated this in Nevada, where he ob- tained as many as three sets of larv?e from one deposition of eggs. In regard to the European dorsalis, since there is but one species in America, there is probably but one in Europe, and dorsalis and curriei may properly be compared. As regards coloration, no differences appear. Unfortunately, we do not know the larva of dorsalis^. The male genitalia are very simi- lar to those of curriei; but we have only a single mount of dorsalis. In that, the two spines of the basal lobe of the side- piece seem more approximate than in curriei. We do not de- tect any other difference ; but on account of the paucity of our information about dorsalis, we must leave the question of the exact relation existing between the American and European forms for the present undecided. A NEW ORTALID FROM THE PHILIPPINES (Diptera, Ortalidce) By FREDERICK KNAB The following new species was reared in the course of in- vestigations by the Philippine Bureau of Agriculture and transmitted by the Entomologist, Mr. D. B. Mackie, to the Bureau of Entomology in Washington for determination. It is described herewith, so that the name may become available. Plagiostenopterina hendeli, new species Female. — Frons dull piceous black, deeply impressed at sides ^F. W. Edwards (Bull. Ent. Res., vii, 217, 1917) mentions the larva of dorsalis thus: "Antennae conspicuously pale at the base; about 24 scales in the comb of the eighth segment; scales pointed ♦ » » and heavily fringed (of the even type) ; teeth of pecten with two or three serrations near the base, of which the apical one is considerably the largest; gills scarcely half as long as the anal segment, bluntly pointed." Unfortunately, the head hairs are not mentioned. 126 INSECUTOR INSCITI^ MENSTRUUS of ocellar triangle, transversely thickened in front ; median portion very finely and closely strigose, with long and very fine, rather sparse hairs. Ocular margins white. Face and clypeus broadly black in the middle, dull ferruginous red at the sides, the antennal grooves silvery pruinose, the intervening ridge less strongly so. Antennae ferruginous red, the third joint pruinose and somewhat darkened at tip and on outer side to near base; arista slightly ciliate basally, the first two joints ferruginous, the part beyond black. Palpi black. Mesonotum metallic green, without pruinosity and with complete median stripe and postsutural lateral stripes darker metallic blue, the surface roughened and clothed with short pale hairs ; trans- verse suture obsolete on the disk ; humeral callosities bright blue, shining, clothed with long white hairs ; macroch?etse black. Scutellum concolorous with mesonotum. Pleurre metallic green-blue, the meso- and sternopleurse white-pilose. Abdo- men shining dark metallic green and violet-blue, the third and fourth segments with broad basal bands of white hair, the fifth segment nearly wholly white-haired; second segment with long outstanding white hairs at the sides. Front coxae and femora bright ferruginous yellow, the latter slightly darkened apically, the tibiae and tarsi wholly black. Middle and hind legs with the coxae black, the femora ferruginous yellow on basal half, blackish beyond ; tibiae piceous, indistinctly reddish on basal half ; tarsi with the first two joints dull ferruginous yellow, the distal ones black. Wiiigs hyaline inclusive of costal cell ; stigma and a large subquadrate apical spot involving apices of third and fourth veins blackish ; no traces of pig- mentation elsewhere ; last section of the fourth vein strongly bent forward beyond its middle ; scale white. Halteres white, the base of stem blackish. Length : Body about 7 mm., wing 5 mm. Male.— Very similar to the female in coloration. Arista without palette. Philippine Islands (Ace. no. 2391, Bur. Agric. P. I.), 4 females, one male. Type, Cat. no. 31552, U. S. Nat. Mus. It gives me pleasure to dedicate this interesting species to INSECUTOR INSCITI^ MENSTRUUS 127 Prof. Friedrich Hendel, of Vienna, who has done so much to advance our knowledge of the Acalyptrate Muscoidea. The extent of the apical wing-spot is somewhat variable. Usually it is limited by the fourth vein, but in one specimen extends well over into the second posterior cell ; in another specimen it stops short of the middle of the first posterior cell. There is also some variation in the mesonotal coloration, the stripes being obsolete or nearly so in some specimens. A NEW AEDES FROM THE ROCKY MOUNTAIN REGION {Diptera, Culicidce) By HARRISON G. DYAR Aedes acrophilus, new species. Head with creamy yellow scales ; a black spot on each side of the vertex and a lateral one below. Mesonotum with golden brown scales, creamy on the lateral margins and antescutellar space; two narrow lines of dark brown, small scales and still narrower posterior subdorsal lines; a narrow central dorsal dark line, formed by the parting of the scales. Abdomen black, with basal segmental white bands, widening at the sides ; venter whitish with traces of medioventral black spots near the apices of the segments. Wing scales black. Legs black ; femora white beneath nearly to tip ; knee spot white ; tibiae largely gray-scaled. Larva. — Head hairs, upper in 5, lower in 4 ; lateral comb of the eighth segment of about 20 scales, evenly fringed, without strong central spine ; anal segment with large plate, not ringed ; air tube moderate, the pecten evenly spaced, the tuft arising beyond it. Type, female, No. 21548, U. S. Nat. Mus. ; Lake Louise, Laggan, Alberta, Canada, August 18, 1906 (Dyar and Cau- dell). Of the described Aedes with black legs from North America, the larvje of the following are unknown : diantaeus Howard, Dyar & Knab, thibaulti Dyar & Knab, aldrichi Dyar & Knab, 128 INSE;CUT0R INSCITI^ MENSTRUUS idahoensis Theobald, prodotes Dyar, plutocraticus Dyar & Knab, balteatus Dyar & Knab, decticus Howard, Dyar & Knab, cataphylla Dyar, nubilus Theobald, fisheri Dyar, ventrovittis Dyar, centrotus Howard, Dyar & Knab, provocans Walker, lugustivittatus Dyar & Knab, obturbator Dyar & Knab, con- dolescens Dyar & Knab, and leucomelas Lutz. Of these, only diantaeus, decticus, prodotes, and centrotus can be compared with acrophilus. A. prodotes inhabits the same general region, the Rocky Mountains, but has a gray mesonotum, like pullatus, whereas acrophilus is golden yellow. The coloration of the adult of diantaeus is unknown, the species being founded on the male genitalia ; but it comes from the mountains of New Hampshire and is probably a different species. A. centrotus and A. decticus are from the region north of Lake Superior. The former has the mesono- tum all brown dorsally as in auroides Felt and provocans Walker, and, therefore, does not agree. A. decticus comes closest, having the same black-spotted head; but besides the different faunal region, decticus has the abdominal bands obsolete dorsally, the tibiae are entirely black without gray scales, and the mesonotal brown stripes are much broader than in acrophilus. It therefore appears that this represents a dis- tinct species. DESCRIPTIONS OF SOME LEPIDOPTEROUS LARV^ FROM MEXICO By HARRISON G. DYAR NYMPHALID^ Peridromia amphinome Linn.
