Expanse 20 mm. HEMEROBIIDAE. NOSYBUS NAVASI, sp. nov. Type. — British Museum. Africa: Gold Coast, Aburi. Patterson coll. Face yellowish, clypeus brownish, vertex with tufts of long white hairs, also on the pronotum; antennae as long as width of fore wings, curled, tapering to tip, rich brown in color. Abdomen brown, with median lobes above, with sparse white hair above and denser yellowish hair on sides; the ovipositor yellowish, about one third the length of the abdomen; legs pale, tarsi yellowish, basal half of hind tibia and apical part of middle tibia dark, legs with mostly long white hairs, but some dark ones.

Venation very similar to N. nobilis Navas, but a cross-vein connecting the second and third branches of the radial sector toward tip, thus four veinlets in the outer series of gradates; hind wings similar to N. nobilis, but no cloud back of the stigma, the latter very distinct. Veins similar to N. nobilis, but the extra apical cross-vein, the lack of cloud in hind wings, several details in color of BANKS: NEW NEUROPTEROID INSECTS. 13 legs, as well as different locality lead me to consider it a distinct species. Expanse 15 mm. Navas has placed this genus in the Hemerobiinae, but its extreme likeness to Dilar, leads me to think it is very near that genus and that the male will have pectinate antennae. It has no close affinity to Neurothus, except the one radial sector, a character of no great value, and liable to variation in the Hemerobiidae. NOTIOBIELLA COSTALIS, Sp. nOV. Type. — British Museum. Africa: Gold Coast, Aburi. Patterson coll. Pale greenish yellow (doubtless green in life); veins green, practi- cally all the forkings (except the marginal ones) clouded, the cross- veins margined, and several other clouds in the cells, one series forming a faint band some distance before the tip; hind wings unmarked. Fore wings about two and a fourth times as long as broad, the costal area extremely broad; at origin of the first radial sector the costal area is nearly as broad as the rest of the wing at that place, the middle series of cross-veins not very oblique, and disjointed. In hind wings the radial sector forks twice before the stigma. Expanse 11 mm. Its broad costal area and shape of superior appendages of the male (Plate 2, fig. 21) separate it from the other described African species of the genus. CHKYSOPIDAE. LEUCOCHRTSA CLYSTERA, sp. nov.

Antennae longer than the head and thorax together, not strongly clavate; pronotum but little longer than broad; legs very slender, the tibia a little longer than femur, the basal tarsal joint as long as the next three together, spurs as long as two joints. Wings broad at stigmal region, very filmy, and very densely veined; at least 75 costals before stigma in fore wing, all simple; radial sector with twelve branches; three cross-veins before radial sector in fore wing, one in the hind wing; about 18 or 20 cubitoanal cross-veins in fore wing; in hind wings the anal runs into the cubital fork; marginal venation extremely dense. Expanse 76 mm. GLENOLEON CONSPERSUM, sp. nov. Type.— M. C. Z. 10,067. Queensland: Herbeton, 11 February. F. P. Dodd. One specimen. Face yellowish; a large interantennal black mark from eye to eye, rather convex below, and straight across above; antennae dark, not banded; vertex brown, with four black spots in a transverse row, and in front two transverse lines; pronotum mostly black, a faint median line, two rounded submedian spots each side on front part, and two oblique sublateral spots on posterior part, all pale; a pale spot on median lobe each side, and pale streaks near and extending on the mesoscutellum; metanotum with a pale streak each side. Abdomen black, faint pale median marks on some of the segments. Femora black, tibiae of front and middle pairs banded with pale near base, before middle, and again toward tip; basal tarsal segment pale, rest, 18 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. dark; hind tibia pale, dark at tip, hind tarsi marked as others. Wings hyaline, veins mostly black, many of them in the fore wings margined with dark, in apical part and behind very densely so; a large spot under stigma, an interrupted dark streak between subcosta and radius; the spots along cubitus rather larger than the others. In hind wing there is a broad stigmal band and a square costal spot beyond dark. The wings are rather broad at stigmal region, tip (Plate 2, fig. 22) acute; near stigma the radial sector bends up to radius as in other species; three cross- veins before radial sector in fore wing, one in hind wing, twelve or thirteen branches of radial sector, costals not forked except near the stigma, in cubito-anal area several of the cross- veins are crossed. In general the venation is similar to G. radiate. Expanse 68 mm. I had labeled this as doubtfully G. falsus, but Petersen's recent figure of that species shows this to be distinct in the heavily spotted fore wings, and the large spot beyond stigmal band in the hind wings. PANOEPIDAE. PANORPA INTERRUPTA, sp. nov. Type.— M. C. Z. 10,068. N. Car. : Raleigh, late September. F. Sherman. Three specimens. Pale yellowish; antennae (beyond basal joints) black; wings hyaline, a trifle flavescent toward base, marked with black much as in P. venom and P. virginica. A fairly broad apical band, a narrow stigmal band, broadly interrupted near middle, two subbasal and a basal spot, and a few other smaller marks; veins mostly dark; the subcosta and most of the radius flavescent; subcosta reaching to the stigma. Male abdomen and genitalia very similar to P. virginica; the horn on fifth segment slender, curved and remote from tip as in that species. The uncus is longer than in P. rufescens; the harpe is not so long as in P. virginica; the clasper has on the upper side a ridge with an apical fringe of hair curving over the uncus; this ridge is similar to but much smaller than in P. virginica. Expanse 22 mm. In appearance similar to P. rufescens, but in genital structure re- lated to P. virginica; the broken stigmal band separates it from P. virginica. BANKS: NEW NEUROPTEROID INSECTS. 19 LlMNEPHILIDAE. LlMNEPHILUS SANSONI, Sp. HOV. Type.— M. C. Z. 10,069. Alberta: Banff. N. B. Sanson. Three specimens. Group of L. combinatus, but more heavily marked with dark. Yellowish, with gray or yellowish hairs; abdomen black, venter paler; front tibiae with mostly yellow spines. Wings yellowish; fore wings heavily marked with brown behind and on the outer part, and a very dark spot at stigma; the two oblique spots on middle across cubitus are very distinct, a large clear spot in base of apical and first sub- apical cells, and another over apical parts of fifth apical and first and second subapical cells; a dark streak along the second anal vein. All the dark brown is broken by rounded hyaline spots. Venation as in L. combinatus, but the fore wings not as elongate. The superior append- ages of female are similar to those of L. combinatus, but the intermediate ones are shorter than in that species, and more acuminate. In the male the superior appendages seen from the side slope more behind, and the lower inner edge not armed with such large teeth as in L. combinatus; the intermediate superior appendages are much larger than in L. combinatus. From L. oslari the female differs in the much longer superior appendages, and in the male the superior appendages are nearly the same shape, but in L. oslari they are very heavily armed with teeth on the inner surface toward tip, while here they are scarcely armed at all; in L. oslari the intermediate superior appendages are smaller and with slightly curved tips. (Plate 1, fig. 8). Expanse 34 mm. Most of the specimens seen appear much like normal L. externus, but not closely related to that species. LlMNEPHILUS ROTUNDATUS, Sp. nOV. Type — M. C. Z. 10,070. Calif.: Lake Tahoe. W. K. Fisher. One specimen. In general marked as in L. gravidus Hagen, the tibiae and tarsi being banded with dark; the fore wings rather more heavily marked than the normal L. gravidus, but on the same plan; the oblique pale spots across the cubitus being distinct; the outer margin of fore wing nearly truncate. Venation like that of L. gravidus. The female differs at once from L. gravidus, L. vastus, and L. intermedium in having 20 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. the inferior appendages short and rounded (instead of triangular) ; the superior appendages are about as stout as in L. intermedius, with the tip slightly pointed and turned upward (Plate 1, fig. 14). Expanse 42 mm. LlMNEPHILUS INTERMEDIUS, sp. nOV. Type.— M.. C. Z. 10,071. Wash.: Olympia. T. Kincaid. One specimen. In general similar to L. gravidus Hagen the tibiae and tarsi banded with dark. The fore wings are rather more evenly marked with dark, a heavy dark band over the anastomosis; shape of wings and venation as in that species, the outer margin being a little convex, and the fourth apical cell in both wings being nearly as broad at base as the third. The female differs from L. gravidus in the genitalia, (cf. Plate 1, fig. 11, 12) the superior appendages being much broader and heavier, but less acuminate than in L. vastus (Plate 1, fig. 13). Expanse 46 mm. LlMNEPHILUS FLAVASTELLUS, Sp. HOV. Type — M. C. Z. 10,072. British Columbia: Wellington. T. Bryant and D. Jones. Two specimens. Yellowish, with whitish or golden hair, leg I blackish on anterior side of femur and posterior side of the basal tarsal joints; the hind tibiae rather brownish, spines black, a few on front tibiae near base may be yellowish. Fore wings yellowish, darker yellowish brown on posterior half and on outer part; a large hyaline spot beyond anas- tomosis, and a curved hyaline streak above the median vein and curv- ing back to cubitus, the brown by the hyaline streak is darker than elsewhere and sharply limited, hind wings hyaline, all veins yellowish. Shape of wings and venation like L. sitchensis, except that the fourth apical cell in both wings is not so much narrowed at base. In the male the lower appendages have a lobe near tip. Genitalia (Plate 1, fig. 16, 17). Expanse 33 mm. HESPEROPHYLAX MAGNUS, sp. nov. Type.— M. C. Z. 10,075. Ariz.: Palmerlee, Cochise Co. C. R. Biederman; Calif.: Santa Ana River, San Bernardino Mts.,30 July, BANKS: NEW NEUROPTEROID INSECTS. 21 J. Grinnell; Fish Creek, San Bernardino Mts., 20 June. J. Grinnell; Tanquitz Valley, 19 July. F. Grinnell; N. Mex.: Ft. Wingate, 21 Aug. J. Woodgate; Utah: Stockton, 22 July. T. Spaulding; Colo.: South Park, 20 Aug., E. J. Oslar. Nine specimens. Colored and marked as in H . occidental-is, but the apical part of the silvery stripe has the sides more nearly parallel, not narrowed at tip, and this stripe is more strongly margined than usual in H. occidentalis. All the specimens are larger than H. occidentalis. It is at once sepa- rated in that the superior appendages of the male are excised on outer edge, with the lower part prolonged; and in the female by having the superior appendages much broader and broadly rounded at tip (c/. Plate 1, fig. 9, 15). Expanse 45 to 50 mm. RHYACOPHILIDAE. RHYACOPHILA ALBERTA, sp. nov. Type.— M. C. Z. 10,073. Alberta: Banff, 27 September. N. B. Sanson. One specimen. cf Brown, clothed with black hair on face, yellowish on vertex and pronotum, tufts of black hair at base of wings; antennae brown, narrowly yellow at tips of the joints; abdomen beneath and genitalia yellowish. Legs yellowish, front and mid tibiae dark on basal half, very pale beyond, front and mid tarsi brown. Wings gray, fore wings rather densely marked with blackish spots and streaks, and with many pale, mostly rounded spots, some along margin; hind wings with tips of some apical veins darker. Maxillary palpi with second joint extremely long and slender; abdomen with long, sparse, fine, erect, white hairs on upper surface, as long as width of abdomen. Fore wings rather elongate; fork 2 reaches before fork 1, fork 4 as long as its pedicel; genitalia similar to R. bipartita, but there is only a minute rounded superior piece visible, and the internal parts are different (Plate 1, fig. 10). Expanse 21 mm. HYDROPSYCHIDAE. ARCTOPSYCHE PHRYGANOIDES, sp. nov. Type — M. C. Z. 10,074. Alberta: Banff. N. B. Sanson. One specimen. Face pale, with black hair, front and vertex black, with yellowish 22 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. hair; palpi pale, antennae pale, tips of joints dark; thorax pale through the middle, dark on sides, pleura pale; abdomen blackish, venter pale; legs pale. Wings longer and more slender than usual; fore wings densely irrorate with dark gray, becoming blackish on the larger spots and on the veins; the larger spots are over the anastomosis, and along the cubital and anal veins. The venation about as in A. grandis, but the cells narrower, and especially the apical cells, the outer margin is thus more oblique. The hind wings brownish, nearly uni- form, but with a few pale spots on outer costal border; venation as in A. grandis, but the pedicel of fork 3 has a spurious vein (really fold) obliquely to the base of fork 2. Expanse 38 mm. Known at once by elongate, heavily irrorate fore wings; probably referred to by McLachlain, Monog. Revis., p. 379, in a footnote. EXPLANATION OF THE PLATES.
