The Pan-Pacific Entomologist Vol. IV, No. 1 July, 1927 SYNONYMIC NOTES (LEPID., PHAL^NIDT:) BY WILLIAM BARNES AND F. H. BENJAMIN Decatur, Illinois Through the kindness of Mr. W. H. T. Tams we have received a copy of “Notes on the Synonymy of Some Noc- tuidas” published 1926, Encyclopedie Entomologique, Lepidop- tera, I, Ease. 4, pp. 183-185. In this paper Mr. Tams has published notes of great value on the types of some heretofore unplaced or misapplied names. As this paper seems unavail- able to most American workers, we think best to call attention to the new synonymy in relation to North American species, “Agrotis” anteposita Gn. 1852, Guenee, Spec. Gen., V, Noct,, I, 278, Agrotis. Mr. Tams remarks that the Paris Museum type is a frag- ment of the thorax bearing two wings on one side. He states it is certainly not Feltia annexa Treit., and thinks it may be '‘Lycophotia” messium Gn. As the species was described from two specimens, one of which was in the Boisduval collection, the second type may pos- sibly be in existence and may be in condition to allow positive determination.

Much has been written reg'arding Hadena and its type. Duponchel, 1829, Lep. Fr., VII, (2), 71, cited g e n i s t £e , but this is not an included name. Curtis, 1830, Brit. Ent., I, 308, cited capsinicola also a non- included name. Boisduval, 1836, Sp. Gen., I, 135, cited den tin a and on page 144 cited s a t u r a, both non-inch;ded names. Westwood, 1840, Gen. Syn., page 95, cited plebeia, a non-included name. Guenee, 1852, Sp. Gen., VI, 81, cited w-latinum pi'esumably for synonym g e n i s t 36 following Duponchel, but neither name included in Schrank’s generic description. Grote, 1874, Bull. Buff. Soc., II, 14, did not designate a type, but in 1895, Ent. Rec., VI, pages 78 and 284, cited cucubali, which he also cited in several subsequent papers. Hampson, 1894, Fauna Brit. Ind., Moths, II, 198, designated type cucubali, the first desig- nation of an included name which we have been able to find. Hampson, 1903, Cat. Lep. Phal., IV, 4, cites type reticulata presumably for synonym typica Auct. and Hbn. nec L., and repeats the citation 1905, 1. c., V, 208. Warren, in Seitz, III, 79, follows Hampson. Fortunately the prior designation of cucubali eliminates the nomenclatorial question if typica Auct., a probable misdetermination. 2 THE PAN-PACIFIC ENTOMOLOGIST [vOL. IV, NO. 1 1926, Tams, Encyc.

We know of no good character to sort glaucopis, which is only western luhens, from typical lubens. Western specimens are often darker in color than some eastern specimens, but the character does not hold for any series. Mr. Tams reports lutra as being from North America instead of from New Holland. In view of the early date of the Guenee name, the comparative rarity of glaucopis in collections, the fact that we cannot tell glaucopis from lubens with any certainty save from locality labels, coupled with the fact that two other supposedly New Holland species described by Guenee from Paris Museum material turn out to be from eastern North America, leads us to think that lutra is, in all probability, based on an example of eastern lubens lubens rather than lubens glaucopis. MyTHIMNA ^ MARYX Gn. 1852, Guenee, Spec. Gen., V, Noct., I, 344, Ceramica. 1905, Hampson, Cat. Lep. Phal. B. M., V, 610, unrecog., Ceramica. could possibly become a genotype, to say nothing of this resting solely on the strength of the citation of reticulata which is a non- included name. McDunnough, 1916, Ent. News, XXVII, 395, follows Grote, but does not use the name for North American species for taxonomic reasons. In all probability lutra (lubens) is not strictly congeneric with cucubali, but quite a number of the species assigned to “Folia” by Hampson and McDunnough do seem to belong, so that we simply substitute H a d e n a for “Folia,” following Hampson’ s taxonomy, until some logical division of “Folia” is proposed. In reality Folia is a Tentamen genus of Cuculliinae, instead of belonging in the Hadeninae. 2 Mythimna Ochs., type Fhalsena albipuncta D. and S. We cannot agree with Dr. McDunnough’s citation of oxalina as type based on a “restriction” method of fixation (1916, Ent. News, XXVII, 395). By this method the type would appear to be acetosell^ D. and S., that name as well as oxalina being listed by Hubner (Verz.), and designated by Grote, 1874, Bull. Buff. Soc., H, 24. We have found no designation of oxalina prior to 1903, Hampson, Cat. Lep. Fhal., IV, 602. Hampson cited oxalina following his “first species” rule, and in this is followed by Warren, in Seitz, III, 61. Westwood, 1840, Gen. Syn., page 94, cited t u r c a , but this was ultra vires in view of the fact that Duponchel, Lep. Pr., VII, (2), 71, had designated type albipuncta. Guenee, 1852, Spec. Gen., V, Noct., I, cited imbe- cilla = disparilis. Barnes and Benjamin, 1926, Ent. News, XXXVII, 79, cited type albipuncta following Duponchel.

The specific synonymy has been explained by Barnes and McDunnough, 1918, save for the name aplectoides. Mr. Tams states this latter name, based on another “New Holland” type in the Paris Museum, is the same as medialis Grt. 3 We possess a specimen from Florida which agrees well with Hamp- son’s figure of vindemialis Gn. (1905, Cat. Lep. Phal. B. M., V, 445, pi. XCI, f. 2 type). The name has been omitted from the Barnes and McDunnough check list because Hampson stated that the locality, Florida, given by Guenee, was presumably an error and that the spe- cies probably came from New Zealand. We tentatively place vinde- mialis Gn. in Barathra Hbn., type albicolon Sepp cited by Grote, 1895, Abh. Nat. Ver. Bremen, XIV, 71. According to Hampson’s taxonomy Barathra will replace Trichoclea. We have had no opportunity to study the European albicolon in relation to North American species. 4 See Barnes and Benjamin, 1926, Pan.-Pac.

Proboscis fully developed; palpi upturned, extending about equally with the frontal armature, the second joint scaled and not conspicu- ously fringed with hair, the third, moderate, porrect; frons with a truncate conical prominence with a fiat vertical corneous process at middle like a beak; eyes rounded, naked, unciliated; antenna of male scarcely serrate, fasciculate, laterally doubly fasciculate from each joint; antennae of female simple, ciliated; head and thorax clothed with broad serrate scales, with very little hair; prothorax with a slight spreading crest; mesothorax with double tufts; meta- thorax with a large scale tuft; all tibiae strongN spined, the fore tibiae also armed distally with two heavy claws on each side. Fore wing with veins 3 and 5 from close to the angle of the cell, 6 from somewhat below upper angle; 9 from 10, anastomosing with 8 to form the areole; 11 from cell. Hind wing with veins 3, 4 from angle of cell; 5 obsolescent from somewhat below middle of discocellulars; 6, 7 stalked or connate, variable individually. Presumably allied to Mesemhreuxoa Hamps. but differing on palpi, antennae, vestiture, and probably also on tibial armature. Mesembragrotis ruckesi Barnes and Benjamin, sp. nov. Head and thorax mixed black, rufous and ochreous; collar with more or less of a transverse black stripe. Fore wing with ground color grayish ochreous, more or less heavily shaded and powdered by black and appearing quite dark; basal line indicated on costa; t. a. line blackish, waved; claviform long, black outlined; orbicular irregularly ovate, variable in exact shape, black outlined; reniform irregular, whitish, black outlined, with more or less of a dusky cres- cent which may or may not have a paler center; t. p. line black, produced to points on the veins, bent outward on costa, more or less incurved in discal fold, and more strongly so in submedian fold; s. t. line dentate, outwardly defined by a pale shade; a terminal series of black points. Hind wing white tinged with fuscous espe- cially on veins and toward the termen. The species has much the appearance of a '‘Euxoa" of the tessellata group. Type locality: near Alpine, Texas (O. C.

We commented upon this genus in our original description. The types of bistrigata, and only examples known to us were both rather poor and considerably rubbed. From a series of another species, described below, and which seems surely closely allied, we would now place the genus in the Cuculliinse, as the eyes appear distinctly lashed, the lashes long but probably easily broken off. In the Cuculliinae Nacopa seems to have no close allies. We are inclined to place it near Euros Hy. Edw. mainly because of its Heliothid habitus. Nacopa melanderi Barnes & Benjamin, sp. nov. Male. Mouse gray irrorated with white; fore wing with basal line as a white dot on costa; t. a. line as a white w-mark; t. p. line white, nearly erect, joined by a curved white mark in cell which takes the place of a reniform and isolates an irregular spot of ground color; s. t. line white, waved from costa to inner margin; fringe pale, checkered. Hind wing pale gray. What we take to be females of the same species are two spe- cimens possessing- exactly the same markings as the males, but with the ground color bright rufous. The species is closely allied to bistrigata, but the male antennae are strongly serrate. In bistrigata there appears to be only two transverse white bands because the upper part of the t. p. and the lower part of the s. t. lines are practically obliter- ated, while the upper part of the s. t. line is practically joined to the lower part of the t. p, line, thus parts of two lines form a single line. The name bistrigata is obviously based on this line and the t. a. line. N . melanderi clearly shows three dis- tinct transverse white lines isolated by ground color. Type locality: near Alpine, Texas (O. C. Poling). Number and sexes of types: Holotype 6, 8-14 July, 1926; allotype 9, 1-7 April, 1926; 13 6 1 9 Paratypes, various dates of May and July. “Polia” buscki Barnes and Benjamin, sp. nov.

(LEPID., GEOMETRID^) BY WULLIAM BARNES AND F. H. BENJAMIN Decatur, Illinois This species was described by Guenee, 1857, Spec. Gen., IX, 437, based on a single female from Canada. A female, figured by Oberthur (f. 3398), is in the Barnes collection. It bears labels “Canada,” “ex Musseo Ach. Guenee,” “Typicum Specimen.” This specimen agrees well with the origi- nal description which is decidedly violated by the species here- tofore placed as lucata. We think it is the type. It is in rather poor condition, without body or hind legs. We have seen no other examples like it. It belongs to the group with . single accessory cell, twelve veins to the primary, unarmed fore tibiae, m. d. c. vein of hind wing nearly erect, short palpi, and dark frons. It has much the markings and appearance of a pale Hydrelia inornata, but with the size of Venusia camhrica. Ten- tatively we leave the species in Hydrelia.

BENJAMIN Decatur, Illinois This insect was described by Guenee, 1852, Sp. Gen., IX, 37, and figured in Atlas, pi. Ill, f. 2. The Barnes collection pos- sesses a specimen bearing labels, “Bdv.,” “Ex Musaeo Ach. Guenee,” “Typicum Specimen.” This specimen exactly agrees with the original description. The transverse lines and black shades have obviously been accentuated by the artist who made the figure as the description states “ — saupoudrees d’atomes noirs qui s’accumulent en une serie peu marquee de taches sub- terminales, avec une ligne fine, peu visible, tres-droite, marquee de points blancs sur les nervures — ” We are convinced that the specimen before us is the type. Other females from St. Petersburg, Florida, closely match it, and the name should be used for the Gulf Strip race of Sahulodes transversata Dru. with transvertens Wlk. as a color form, slightly paler but with more heavily marked t. p. lines. The form heretofore going as incurvata was determined in the Guenee collection as transversata, which accounts for Guenee having renamed the typical transversata, goniata.

Muzzall at Camp 20, Hammond Lumber Company, Humboldt County, California, June and July, 1916. The host tree was not identified. This species has a color pattern very close to that of Pissodes terminalis Hopping,^ but it differs greatly otherwise, for it has a more robust and shorter rostrum and the hind angles to pro- thorax obtuse and somewhat rounded, not sharply right angled. In Hopkins’ Monograph of Pissodes,^ it would fall in his key to the species very close to similis Hopk., but can be separated from the same by being larger with the rostrum and prothorax both more robust, the latter with hind angles obtuse and some- what rounded, the elytra with alternate intervals more elevated and color pattern more conspicuous. From Pissodes barberi Hopk., which occurs in its territory, it differs definitely by being 1 A New Species of the Genus Pissodes (Coleoptera), by Ralph Hopping, Can. Ent.

IV, NO. 1 reddish brown, not black, with the anterior elytral color patch rather large, not indistinct, and the posterior very large, not small. Pissodes costatus Mann., which also simulates it, lacks the very robust rostrum and prothorax, the somewhat rounded hind angles to latter, the rather large anterior color patch, and in addition has the posterior spot anterior to the declivity. Pissodes ochraceus Van Dyke, new species Robust, reddish brown, pronotum with the usual two patches of white scales and in addition a few buff scales in front, elytra with a subbasal patch of ochre colored scales, of moderate size, and a large transverse patch of scales of the same color, surrounded by a black margin, anterior to the elytral declivity, and a few scattered white scales both above and beneath. Head moderately coarsely, densely punctured in front, a shallow fovea between the eyes; beak equal in length to prothorax, robust, coarsely, densely punctured at base, finer apically. Prothorax slightly broader than long, almost as broad as elytra, ver}'- convex, hind angles obtuse and blunt, sides broadly and evenly arcuate until near apex where suddenly con- stricted, disk coarsely, closely punctured and with fine carina at middle. Elytra twice as long as prothorax, third and fifth intervals distinctly elevated, the seventh to a lesser degree, the fifth tubercu- late posteriorly, the stria coarsely, not closely punctured. Length 6.5 mm. from base of beak to tip of elytra, beak 2 mm., breadth 2.5 mm. Holotype (No. 2465, Mus. Calif. Acad. Sci.) and one para- type in my collection, taken by myself at Meadow Valley, Plumas County, California, June 6, 1924. The host tree could not be located. The distinctive color pattern of this species readily separates it from all of our other species. Structurally, it somewhat resembles the preceding but has a slightly narrower and more cylindrical beak, less coarsely punctured, more suddenly nar- rowed prothorax in front, and the posterior elytral maculation anterior to the basal declivity. In this latter regard as well as by its general shape, it closely approaches Pissodes costatus Mann, and is no doubt somewhat related to it. Anculopus Van Dyke, new genus Moderately elongate and somewhat flattened; beak free, not flexed, moderately robust, somewhat shorter than prothorax, slightly curved, suddenly constricted at base and just behind eyes, the apical por- tion slightly wider than basal, antennse inserted toward sides one- third from apex and with insertion visible from above, the scrobes deep, bent backward and beneath to inferior margin of eyes where July, 1927] VAN DYKE RHYNCtlOPHORA 13 somewhat dilated, mandibles biemarginate and tridentate at tip; eyes not large but protuberant and slightly angulated at apex; antennae with first segment of funicle longer than broad, the four following transverse and gradually broader, the terminal forming a compact fusiform club. Prothorax longer than broad, the prosternum slightly emarginate in front, the front coxae narrowly separated by prosternal spine. First and second ventral segments each considerably longer than third and fourth united, the triangular suture separating them finely yet distinctly defined throughout. The femora moderately clavate, tihiae rather long, curved near apex, with corbels and a long oblique claw at apex which is dilated and ciliated basally. Genotype, Anculopus foveatus Van Dyke. This genus undoubtedly belongs very near Paraplinthus and as such within the tribe Hylobiini as defined by LeConte and Horn."'' The more restricted tribe given by Blatchley and Leng ^ would not receive it because of the distinct though narrow separation of the front coxte though it possesses all of the other characters called for. I believe that the Pissodini should be kept distinct from the Hylobiini as has been done by the latter workers, but I also believe that the second tribe should be extended so as to admit this genus, for it without doubt belongs here. From Paraplinthus and other members of the tribe, it differs by the narrow separation of the front cox3e as well as by the peculiar stalk-like formation of the eyes, the latter character separating it from all weevils which might be confused with it. Anculopus foveatus Van Dyke, new species Somewhat elongate, slightly flattened above; black, the rostrum, antennse and legs rufopiceous. Head with basal portion smooth and shining, rostrum coarsely, shallowly and sparsely punctured basally, more finely, distinctly and closely apically. Prothorax distinctly longer than broad, apex truncate above, base slightly arcuate, sides broadb'^ arcuate, constricted in front, disk moderately convex, a narrow and smooth longitudinal carina at middle, elsewhere opaque and deeply pitted or foveate, the foveas well spaced and with a minute golden scale at the bottom of each.

Length including beak, 6 mm.; breadth, 2 mm. Holotype (No. 2466, Mus. Calif. Acad. Sci.), a unique in my collection, taken by myself at Humptulips, Washington, May 28, 1914. This deeply pitted species superficially resembles the Euro- pean Epipolacus (Plinthus) caliginosus (Fabr.) and some of the more robust Cossoninse, but no weevil that we have in this country. It no doubt has habits somewhat similar to Paraplinthus carinatus (Mann.), for it was found in deep coniferous woods just as that is. Acmaegenius granicollis Van Dyke, new species Robust, black, subopaque, sparsely clothed with rigid hair, moder- ately dense and suberect on elytra, and with a few scattered white scales. Head somewhat shining, coarsely, densely punctured; beak broad, deeply grooved above, with less defined lateral grooves, and scrobe deep and broad to lower margin of eyes; antennae less com- pact than in hylobinus and with second funicular segment propor- tionally longer. Prothorax as long as broad, hardly narrower at apex than base, sides moderately arcuate, disk convex, densely punc- tured and with intervals elevated into shining granules or small irregular tubercles. Elytra oval, almost twice as wide as prothorax and about two and a half times as long, disk very convex, striae coarsely, moderately closely punctured, intervals vaguely convex and rather densely, irregularly punctured. Beneath rather densely, mod- erately finely punctured and rugose. Length including beak, 10 mm.; breadth, 4.25 mm. Holotype (No. 2469, Mus, Calif. Acad Sci.), a unique in my collection from Carbon County, Wyoming. This species superficially looks like some of the smaller, more rubbed specimens of the only other species of the genus, hylobinus, but it definitely differs by having a prothorax that is evidently granulate above, merely punctate in the other, as long as broad, whereas broader in the other, and with the apex hardly narrower than base in contrast to a much narrower apex in the other ; with the scrobe almost touching the eye, while it does not in the other ; and with the underside evidently rugose. In my series of fifteen specimens of hylobinus from south- eastern Oregon and northeastern California, there is con- July, 1927] van dyke — rhynchophora 15 siderable variation especially as regards the distinctness of punctation of the elytral intervals, but none of them approach the other species in regard to the characters mentioned as defining it. Trichalophus brunneus Van Dyke, new species Large and robust, black, upper surface clothed with small cupreous brown scale-like hair, interrupted here and there along the line of the strise, and with a conspicuous patch of silvery scale-like hairs along the sides of prothorax, a rounded patch on the disk of each elytra one-fourth distance from the base and a double patch on the sides of the elytral declivity on what would correspond to the fifth and sixth intervals, also a few small patches defining the lateral striae, the underside with the pro-and mesosternum densely covered with brownish white scales, the abdomen with a few similar scales at sides, elsewhere finely pilose. Head with deep groove on upper surface of rostrum, lateral grooves moderately deep and triangular and the scrobe deep as usual. Prothorax slightly broader than long, evidently transversely impressed near apex, sides slightly arcuate in front of middle, disk evenly convex, moderatelj'’ coarsely, densely punctured and finely granulate, a fine longitudinal carina at middle with a small fovea in front. Elytra about three times as long as prothorax and not quite twice as wide, very convex, apical declivity abrupt, apices divergent and dentate, discal strise vague, lateral faintly impressed. Beneath with outer hind margin of fourth ventral segment dentate as in didymus and constrictus. Length including rostrum, 13 mm.; breadth, 5.5 mm. Holotype (No. 2470, Mus. Calif. Acad. Sci.), a unique in my collection, taken by myself in the Yakima Indian Forest Reserve, altitude 3000 feet, on the east slope of Mount Adams, Washington, July 1, 1925. This large and handsome species with the four silvery elytral spots standing out more conspicuously than in any of the other species against the rich coppery brown background, should make it readily recognizable. In LeConte’s table ° it would come close to constrictus (Lee.). In this connection I wish to state that my series of specimens seem to prove that didymus (Lee.) and constrictus (Lee.) are but phases of the same thing as was surmised by Le Conte. Both are often found in the same territory. These two also pos- sess along with brunneus, a very prominent tooth on the outer posterior margin of the fourth ventral segment, a character which is not present in the other species. 6 The Rhynchophora of America, North of Mexico, by John L.

IV, NO. 1 Trichalophus foveirostris Chittenden ® This insect belongs, I believe, in the genus Plinthodes Lee. rather than in Trichalophus. I have had several specimens of it in my collection for many years. They were taken in the coniferous forests on the top of Mount Mitchell and the adja- cent peaks of the Black Mountains of North Carolina, during June, by Mr. William Eeutenmueller and myself. This species is smaller and the females more robust than tccniatus. In addition it is brown in color, with a more general dispersal of scale-like hair, has a shorter rostrum with shorter and broader lateral grooves, more prominent eyes, more finely rugose pronotum, narrower and slightly convex elytral inter- vals which are also more finely rugulose, and the third and fourth ventral segments broader. In some ways it strongly suggests some of the species of Trichalophus, especially as regards its size, color and vestiture, but its generic characters are eminently those of Plinthodes. PhlcEOphagus californicus Van Dyke, new species Elongate, subparallel, smooth and shining, rufopiceous. Head with eyes evidently protuberant, rostrum slightly longer than one-half length of prothorax, robust, distinctly and sparsely punctured; antennae with first segment of funicle evidently longer than broad, second to seventh closely united, transverse and gradually broader, the club elliptical. Prothorax slightly longer than broad, sides rather evenly arcuate, constricted near apex, disk rather deeply, coarsely punctured, the punctures separated by a distance equal to their own diameter, finer near anterior margin. Elytra twice as long as pro- thorax, barely vnder, sides parallel for basal three-fourths, broadly rounded to apex, stria; deep, rather coarsely, closely punctured, intervals perceptibly convex and crenulate, with a single series of fine punctures, the two outer longer intervals more or less finely carinate, the outermost evanescent before apex, the sulci on either side, therefore, blending near apex. Beneath rather coarsely, sparsely punctured, finer and closer on three anal segments. Length includ- ing rostrum, 3.75 mm.; breadth, 1.25 mm. Holotype (No. 2471, Mus. Calif. Acad.

This species is larger than any of the species listed from eastern North America except Codiosoma (Phlceophagus) spadix (Herbst.) and is readily separated from that by being elongate subparallel and not pilose. It is also separated from Phlceophagus apionides Horn and variolatus Dury by its larger size as well as sparser pronotal punctation. From Phloeophagus minor Horn which it was questionably determined as many years ago, it differs by being larger, with rostrum broader at base and not dilated apically, by having the eyes more promi- nent, prothorax less narrowed forward, and much coarser punctation, especially of pronotum. Phloeophagus canadensis Van Dyke, new species Similar in general appearance to californicus but a bit larger, more robust; the rostrum less dilated, eyes hardly projecting beyond side margins of head, first segment of funicle as broad as long, prothorax more robust and inclined to have sides somewhat parallel at middle, elytra more attenuated posteriorly and the two outer longer elytral intervals, eighth and ninth, carinate posteriorly, the outermost reach- ing the apex.

Head short; anterior spines very short, blunt; median and posterior spines not very long, contiguous with the sur- face of the head. Bucculae long, narrow, closed in front. Rostral channel open behind, the rostrum reaching almost to the venter. Odoriferous canal long and prominent. Antennae long, brownish; segment I much stouter and a little longer than II; III very long, two and one-half times the length of IV; IV long, clothed with moderately long hairs, black, except small basal portion. Pronotum tricarinate; the lateral carinae short.

Prothorax with a large piceous median space, sometimes shad- ing gradually into the paler color of the sides, distinctly and moder- ately closely punctate, the arcuate and transverse series of coarser punctures and basal marginal line distinct. Elytra punctured simi- larly to the thorax, with the punctures less impressed toward the apex, the usual series of coarser punctures distinct. Body beneath piceous, opaque, prosternum strongly carinate, the carina more elevated in front, mesosternal lamina very prominent with an acute angle, femora piceous, tibis and tarsi rufo-testaceous, tarsal claws as in ochraceus, last ventral segment emarginate at middle. Length, 3.5-4 mm. This species closely resembles ochraceus in shape and color, but is easily recognized by its carinate prosternum and strongly laminate mesosternal protuberance. From nebulosus it is sep- arated by its color and the piceous space at middle of pronotum. My description is based on a series of twelve specimens from Riverside and Santa Barbara, California. E. nebulosus (Say) occurs from Canada to Florida and west- ward to Indiana and California. I have seen specimens from Claremont, N. H. (Coll. Dow) ; Pinehaven and Rockaway Beach, L. I. (Coll. Shoemaker) ; Ithaca, N. Y. (Coll. Rich- mond) ; Nashville, Tenn. (Coll. Dodge) ; Paradise Key, Fla. (Schwarz and Barber) ; Tompkins Cove, N. Y. ; Jekyl Island, Ga. ; Porto Rico (Amer. Mus. Nat. Hist,, N. Y.) ; and Rich- mond, Va. The variety pectoralis (Lec.) is confined to southern Cali- fornia and is distinguished by the minute punctuation of the upper surface, and averages smaller in size and is less convex in form than typical nebulosus. It occurs in brooks, my speci- mens being from Ventura and Riverside, California. 22 THE PAN-PACIFIC ENTOMOLOGIST [vOL. IV, NO. 1 E. calif ornicus (Horn). This species resembles in form and color, Cymbiodyta dorsalis (Mots.), but is easily separated from that species by its generic characters. Specimens when not fully mature are brownish testaceous, but change to piceo-testaceous upon reaching maturity. The second maxillary palpus at basal half, and terminal joint at tip are darker, the coarser arcuate series of punctures on prothorax and basal marginal line are distinct, the coarser punctures of elytra indistinct, and the last ventral segment emarginate. This species seems to prefer stand- ing water. My specimens are from Santa Barbara and River- side, California. E. cinctus (Say). This large piceous species could only be compared with E. consors (Lee.), but its testaceous maxillary palpi, indistinct basal marginal line and untoothed male claws will easily separate it. It prefers standing water and occurs, according to Doctor Horn, from Canada and the New Eng- land States south to Georgia and west to Kansas. Blatchley records it as throughout Indiana, and Leng and Mutchler, from Lake Worth and Lake Okeechobee, Fla. I have seen speci- mens from New Haven, Conn. ; Lakehurst and Hackensack Meadows, N. J. ; Flatbush, Rockaway Beach and Kissenor Lake, L. I. ; Stoneham, Mass. ; Chicago, 111. ; and the Catskill Mountains, N. Y. E. consors (Lee.). The piceous maxillary palpi will separate this from the other members of its genus, I have seen speci- mens from Brookville and Lakehurst, N. J. ; Pablo Beach, Fla. (Coll. Dodge) ,* Writesville, N. C, (Coll. Davis) ; and Paradise Key, Fla. (Barber and Schwarz). E. blatchleyi (Fall) is piceous black, formed nearly as in nehulosus, thorax somewhat paler, ventral apex with a minute emargination, protarsal claws of male each with a moderately strong, nearly rectangular basal tooth, and the prosternum not carinate. I have seen no specimens. Professor Fall records it from Dunedin, Tarpon Springs, and St. Petersburg, Fla. E. per pie XUS (Lee.). This may easily be recognized by its piceous color, elongate form and non-emarginate last ventral segment. It is common from Canada to Florida. My speci- mens are from Hackensack Meadows, N. J. ; Kissenor Lake, L. I.; Ottawa, Ont. (Coll. Beaulne) ; Writesville, N. C. (Coll. Davis), and Stone Mountain, Ga. (Cornell University). July, 1927] WINTERS HELOCHAR^ 23 E. conjunctus (Fall). According to Professor Fall, this spe- cies much resembles E. carinatus (Lec.) in color but is much smaller and less convex and, by the palpal characters, belongs to a different section of the genus. The claws are toothed somewhat after the manner of E. hamiltoni (Horn). It was described as from Lake Tahoe, California. E. reflexipennis (Zimm.). This species may easily be recog- nized by its pale head and testaceous surface. It is a saltwater species found on the coast of Connecticut and Long Island. I have seen specimens from Norwalk and the saltwater marshes near New Haven, Conn., North Beach and the marshes of Rockaway Beach, L. 1. (Coll. Shoemaker), and Staten Island. E. hamiltoni (Horn). This species is as a rule more broadly oval than the following and the thorax has a large piceous space at middle. It is common in salt as well as fresh- water marshes and is recorded from Canada to Florida and westward to Cali- fornia. I have seen specimens from Rockaway Beach, L. 1. ; Staten Island; Yonkers, N. Y. ; Chesapeake Beach, Md. ; Tiver- ton, R. 1. ; Stoneham, Mass. ; Orono, Me. ; Chicago, 111. ; Wathena, Kan. (Coll. Dodge) ; Cornwall, Conn. (Coll. Cham- berlin) ; and Paradise Key, Fla. (Schwarz and Barber). Pro- fessor Blatchley records it as frequent in Lake, Starke, and Luparte counties, Indiana. E. diffusus (Lee.). This species while closely resembling hamiltoni is much more oblong in shape and has no thoracic piceous space, and the anterior claws of the male are more everted. Doctor Horn records it from Illinois, Dakota, Wyom- ing, Nebraska, and California. My specimens are from Santa Barbara, California, caught in marsh land along the seashore. It seems to be rare in collections and I have seen none from the Atlantic coastal regions. Genus Helochares Muls. This genus differs from Enochrus by its maxillary palpi which are shaped like those of Cymbiodyta, from Cymbiodyta by its five-jointed middle and hind tarsi and slightly emargi- nate last ventral segment, and from both by having the clypeus more broadly rounded in front and the apex deeply emarginate, exposing the labrum to a larger extent. This is the only genus in the Hydrophilidae, so far as known, where the female attaches its egg cases to the abdomen until the larvae are hatched. 24 THE PAN-PACIFIC ENTOMOLOGIST [vOL.

Prothorax distinctly punctate, transverse series of coarser punctures very prominent, basal marginal line absent. Elytra distinctly punctate, punctures toward apex less deep with a distinct series of coarser punctures along the middle, and two others less distinct external to these; sutural striae absent.

Doctor Horn records it from Ohio to North Carolina, Florida, and Texas ; Professor Blatchley from Dunedin, Fla. ; Leng and Mutchler from Eson River, Fla. ; and Uhler from Washington, D. C.

The subgenus Chasmogenus Sharp is founded on a species that is non-striate, except for the sutural striae, with very long maxillary palpi, as long as head and pronotum together, with mentum deeply emarginate, and mesosternum carinate. The ten-striate elytra and comparatively short maxillary palpi place this species in Hydrohaticus, a view which has been taken by both Orchymont and Knisch. It occurs in the slowly flowing waters of southern California and seems not to object to warm springs. My speci- mens are from Ventura, Santa Barbara, Riverside, and Arrow- head Hot Springs, California. Doctor Horn records it from San Francisco southward into the Peninsula of California and eastward to Arizona. Genus Helobata Bergr. This genus is peculiar in having the labrum concealed under the clypeus ; mentum transversely quadrate, its triangularly, apparently elevated, area at center slightly concave and with a small circular emargination in front, obliquely impressed on each side where it joins the submentum; maxillary palpi very long and in the specimens before me with a tendency to fold between the elevated triangular center and submentum ; clypeus projecting laterally in front of the eyes to a great extent; pro- thorax and elytra broadly margined, the latter extending beyond the tip of the abdomen. According to Doctor Sharp, the anterior coxal cavities are closed behind by the junction of the epimera with the prosternal process, a character which isolates this genus from all other Hydrobiini although in other respects it is approached by various species of Helochares. H. striata Brulle. This species has been known to us hereto- fore as Helopeltis larvalis Horn. I have two specimens before me from Florida which present the following characters : slightly piceous or somewhat testaceous in color ; head and pro- thorax obsoletely rugulose, smoother at sides ; apex of prothorax emarginate, arcuate series of coarser punctures absent; scu- tellum elongate triangular, scutellar striaa distinct ; elytra obso- letely rugulose, explanate at sides, with ten punctate striae, the last two close together, leaving a narrow interval between; the side margins wide, explanate ; prosternum and mesosternum simple ; last ventral segment emarginate at apex, the femora pubescent and tibiae finely spinulose. 26 THE PAN-PACIFIC ENTOMOLOGIST [vOL, IV, NO. 1 Doctor Horn records it from Louisiana and Sonora; Doctor Sharp from Guatemala, Paso Antonia, 4000 feet, and Cuba; Leng and Mutchler, Florida (Roberts’ Coll.) ; Blatchley, Sara- sata, Florida, March 4, beneath chunks of debris half buried in the mud of tide- water marsh; and Knisch, southern part of North America, West Indies, Central and South America.

It is not rare in the mountain streams of the Coast Range of southern California. My specimens are from Camp Meeker, northern California, and Santa Barbara. C. fraterculus Sharp. I have no specimens of this before me. Doctor Horn records it from southern Arizona well into Mexico. C. imhellis (Lee.). This species is as a rule recognized by its brownish elytra, though in some cases its color approaches that of dorsalis. Its clypeus is narrowed toward apex in a slight curve with its front straight; its maxillary palpi are longer than in punctatostriata or dorsalis, with the second segment at base and terminal at apex darker. The arcuate series of coarser punctures of prothorax are very pronounced and the elytral striae consist of much finer and only slightly impressed punc- tures as compared with dorsalis. Doctor Horn gives the number of entire striae as five, but they are by no means constant. In my specimens from Camp Meeker five striae are plainly dis- cernible while in those from Santa Barbara they are reduced to two. C. morata Horn and dorsalis resemble each other very closely. In both the clypeus is almost semicircular and slightly arcuate- emarginate in front, the prothoracic punctures of systematic value are very much reduced, and the maxillary palpi are shorter comparatively than in imhellis. I have found that the only way of separating morata from dorsalis is by its average larger size and the greater prominence of the coarse interstitial punctures. I have studied thirty specimens from Jemez Springs, Ariz. (Coll. Sherman), and three specimens from Yuma County, Ariz., June (Coll. Dow). C. dorsalis (Mots.) seems to prefer mountain streams at lower altitudes and is common in southern California. My specimens are from Camp Meeker, Santa Barbara, Santa Cruz Island, Ojai, and Riverside. C. rotunda (Say). This species is the most broadly oval of any in this genus. Of its maxillary palpi I can unfortunately say nothing, as they are both missing in the two specimens before me. The mesosternum has the transverse ridge broadly pyramidally elevated, and one of my specimens, a male, has the 28 THE PAN-PACIFIC ENTOMOLOGIST [vOL. IV, NO. 1 last ventral segment slightly emarginate at the middle of the apex, which is unique in this genus. It seems, while widely distributed, to be extremely rare in collections. My specimens are from Westwood, N. J., and Pennsylvania (collection by Henry Ulke in 1890). Doctor Horn records it from the Middle States as far south as North Carolina. C. minima Not., Bui. Brooklyn Ent. Soc., XIV, 1919, p. 133. It was described from three specimens collected at Mooers, Clinton Co., N. Y., September, 1918. I have seen no speci- mens, but according to the description it is recognized by its small narrow form, 2.75-3.5 mm.; transverse row of coarser punctures of prothorax and rows of coarser punctures of elytra indistinct; nonstriate except for sutural striae, with the mesos- ternal ridge strongly and acutely elevated at middle. C. acuminata Fall, Journ. N. Y. Ent. Soc., XXXII, June, 1924. According to Professor Fall this species resembles in its general aspect smaller specimens of C. vindicata Fall or Enochrus per plexus (Lee.), with the pale margin of the pro- thorax extending narrowly across apex and vaguely inward for a short distance along base. The mesosternal transverse ridge is elevated into a long subconical acute spur. C. blanchardi Horn, This species is easily recognized by its small broad form and pale space in front of each eye. It seems to prefer swift-running water. My specimens are from Ardsley on Hudson, N. Y., Halden, N. J,, and Richmond, Va. Others seen were from Woodland, N. J. (Coll. Dow), Fairfax County, Va. (Coll. Shoemaker), Yonkers, N. Y. (Coll, Angel), and Cornwall, Conn. (Chamberlin). C, fimbriata (Melsh.). We have to thank Professor Fall for the proper identification of this species which has long been confused with vindicata Fall or Zimmerman’s semistriatus. Fimbriata is more convex, with elytra distinctly narrowed pos- teriorly almost from the basal fourth, and is much rarer than vindicata. My specimens are from Van Cortland Park, N. Y., and Westwood, N. J. Professor Fall records it from New Hampshire and Massachusetts. C. vindicata Fall. This species is common from Canada to Texas. I have seen specimens from Kissenor Lake, L.

Dow) ; Ithaca (Coll. Richmond) ; Orono, Me. (Coll. Dodge) ; Cornwall, Conn. (Coll. Cham- berlin) ; and Richmond, Va. This species has heretofore been known as C. fimbriata (Melsh.). C. lacustris (Lee.). This species is of an oblong form, with coarser punctures of elytra absent and the transverse ridge of mesosternum short. It is not rare, occurring from Lake Superior to New England. My specimens are from Kissenor Lake, L. I., Hackensack Meadows, N. J., Cornwall, Conn. (Coll. Chamberlin), New Haven, Conn., Flatbush, .L. I. (Coll. Shoemaker), and Framingham, Mass. (Coll. Dodge). Genus Helocombus Horn Tarsi heteronierous, maxillary palpi very long, curved as in Cymbiodyta, prothorax without basal marginal line, elytra deeply striate, resembling in form and structure Hydrobius fuscipes L., but easily separated from it, aside from its more important structural characters, by its long maxillary palpi. H. bifidus (Lee.). Doctor Horn records it from Canada and the Lake Superior region and the New England States southward to Georgia. I have seen specimens from Forest Park, L. I., in a pool among leaf mold, Weehawken, N. J. (Amer. Mus. Nat. Hist., N. Y.), Fall River, Mass. (Coll. Dodge), Ottawa (Coll. Beaulne), and Staten Island, N. Y. (Coll. Davis). Professor Blatchley records it as frequent in the lakes of the northern half of Indiana. Note on Western Bulb Flies In the past the syrphid fly Eumerus strigatus Fall, has been designated as the lesser bulb fly or onion fly, but it now appears that there are at least three species of Eumerus in the western states, two of which are quite common. The bulb flies are of considerable economic importance, and a careful study of sev- eral thousand specimens reared from infected bulbs in Wash- ington, Oregon, and California should yield some interesting results. The commonest species in California is Eumerus tuberculatus Rond. Experimental work with these flies is being carried on at the United States Bureau of Entomology Field Station at Santa Cruz. — F. R.

This species has the general appearance of a Limothrips Hal., but with head broadly rounded in front, without thorns on the ninth tergite and with seven-segmented antenna. If the maxil- lary palpi were two instead of three segmented, it would more nearly resemble Baliothrips Uzel.

Host : Bromus carinatus, growing under giant redwoods. All types in author’s collection (Reg. No. 968). This species may be distinguished from hcsmorrhoidalis Bouche by its more slender body, transparent wings except at the extreme tip, and the brown shading in the middle of all femora and tibiae, and from fasciatus Linn, by the absence of cross bands on the wings, and by the predominating color of the legs being light yellow shaded with light brown as com- pared with the dark brown in fasciatus. Heliothrips gossypii Moulton, new species Female, holotype. Color yellowish brown with darker brown shad- ings giving a mottled effect. Legs yellowish to brownish white with all femora and tibise shaded brown in the middle.

Eyes prominent, not protruding, occupying slightly more than half the length of the head, with large facets, pilose. Ocello approximate. Antennae twice as long as head, typical of the genus in shape. Prothorax with indistinct reticulations, without prominent spines except a pair of rather short transparent ones on each posterior angle. Wings fully developed, seventeen times as long as width at middle, fore vein fused with costa beyond fork; costa with nineteen to twenty prominent spines and without fringe; principle vein with two spines near base and two near fork. The first three are trans- parent and inconspicuous, the fourth is at the fork and dark brown. One spine at fusion of anterior vein with costa and two on inner side of costa near tip, the distal one being within the darkened band and dark brown. Posterior vein with four spines, the first and third are within the white areas, and are transparent, the second is within the median brown band and is dark brown, the fourth is within the outer white area but dark brown (female paratype with six spines on posterior vein).

Light impressions on ventral side of seg- ments three to seven long and narrow, extending almost entirely across sternal plates. Segment nine with one pair of short stout dorsal spines near median line and two pair of longer spines near posterior margin, the inner pair of which are longer than the outer. Described from seven female and three male specimens taken at Phoenix, Arizona, in August, 1926, by Mr. J. H. O’Dell, from cotton plants, and at Calexico, California, in September, 1926, by Mr. E. A. McGregor, from citrus foli- age. All types in author’s collection (Reg. Nos. 1155, 1413). This species may be distinguished from H. phaseoli Hood, as follows : in gossypii the antennas are about twice as long as the head, and head is .2 longer than prothorax; wings have three darkened cross bands and are about seventeen times as 34 THE PAN-PACIFIC ENTOMOLOGIST [vOL. IV, NO. 1 long as width at middle; in phaseoli the antennae are 2.4 times as long as the head, head and prothorax of equal length, and wings thirteen times as long as width in middle. H. gossypii may be distinguished from indicus Bagn., the cotton thrips of India, by its lighter body color, smaller size, more slender wings, and different sculpturing. Odontothrips californicus Moulton, 1907 This species was originally described as a variety of Hali- day’s Odontothrips (Thrips) ulicis. Dr, H. Priesner’s recent studies (Ref. Die Thysanopteren Europas, 1926, Part I, p. 222), show that the ^‘"ulicis” Haliday’s group have two strong teeth at the end of the fore tibiae, while the ^dati” Hal. group has only one tooth and the second is represented by a bristle-bearing wart. O. calif ornica Moult, belongs to the second classification and the name ^'ulicis” is misleading and therefore withdrawn. This species is closely related to 0. lati Hal. Rhopalandrothrips corni Moulton, new species Female, holotype. Color pale yellowish white, pterothorax slightly orange-yellow. Antennae: segments one, two, basal half of three, and basal third of four, yellowish white, distal half of three light grayish brown, outer half of four and five to eight dark grayish brown. Wings transparent, veins yellowish white, prominent spines brown. Crescents of ocelli bright orange. Measurements: Total body length .83 mm. Head, length .066 mm., width .11 mm.; prothorax, length .083 mm., width .13 mm.; ptero- thorax width .166 mm. Length of antennal segments, I, 15 microns; II, 30; III, 45; IV, 37; V, 30; VI, 45; VII, 9; VIII, 12; total length 225 microns. Head transverse. Eyes prominent, protruding, facets large, pilose. Ocelli well developed. Interocellar spines prominent 39 m. long and placed near inner anterior margin of posterior ocelli. Mouth cone long, pointed, reaching beyond posterior margin of prosternum. Antennae almost three times as long as head, five smallest and six largest of intermediate segments. Prothorax with two long spines on each posterior angle (39 m.) and a third pair (30 m.) along posterior margin. Wings well devel- oped reaching tip of the abdomen, veins clearly defined, with three cross veins between costa and fore vein, one opposite forking of longitudinal veins, one near middle of wing, and the other at the tip where fore vein fuses with the costa broadly in two or three places. Posterior vein ending abruptly just before the tip. Costa bearing seventeen to nineteen spines, fore longitudinal vein with five at base and two at extreme tip, posterior longitudinal vein with July, 1927] M 0 ULTO N T H YS A N O PTERA 35 nine to ten evenly placed. Ninth abdominal segment with a row of six long spines (60 m.) along posterior margin. Tenth segment with a pair of long median spines near the tip (69 m.) and a shorter pair on the sides (45 m.). Allotype, male. Color as in the female. Total body length .56 mm. Length of antennal segments, I, 15 microns; II, 33; III, 33; IV, 30; V, 21; VI, 84; VII, 9; VIII, 12; total length 237 microns. Head conspicuously transverse with eyes large, rounded and occu- pying almost the entire side of the head. Ocelli fully developed. Sixth antennal segment four times as long as segment five and nearly three times as long as segments three and four. Prothoracic spines as in the female but shorter. Wings fully developed surpassing tip of the abdomen, veins and spines as in the female. Ninth abdominal segment with a row of six long spines along posterior margin. Described from twenty female and eight male specimens taken at Big Trees, Calaveras County, California, in August, 1926, by the writer from the foliage of dogwood and maple and from Bromus sp. All types in author’s collection (Reg. Nos. 967, 968, 970). The female of this species is very similar to Tcsniothrips costalis Jones, but smaller, .83 mm., as compared with 1.33 mm. in costalis, and by the long-pointed mouth cone. Jones describes the mouth parts of costalis as “short and blunt.” The enlarged sixth antennal segment places this species clearly in Priesner’s Rhopalandrothrips, and this is the first member of this genus to be recorded from California. Liothrips varicornis Hood, 1912 A collection of five specimens of thrips taken at Marysville, California, in December, 1926, by Mr. H. A. Crane, from hollyhocks, can be assigned to the species varicornis Hood, with the following notations ; Antennal segments three, four, five, and six distinctly shorter than as given in the original descrip- tion, and with a median longitudinal streak in the hind wings as in the fore pair, fading just before the tip. Otherwise, the specimens in this collection are apparently identical with varicornis ; blackish brown in color with only the third antennal segment abruptly yellow and the longitudinal bars of the fore wings extending to near the tip. This thrips has been known heretofore only from Monterey, Mexico, taken from weeds and grass. 36 THE PAN-PACIFIC ENTOMOLOGIST [vOL.
