ocellar furrow wanting; lateral ocellar furrows narrow, deep, extending from near 

 occiput to antennal foveae. Third and fourth antennal joints equal. Head and 

 dorsulum finely, closely punctured ; head perhaps more closely so. Mesopleurae not 

 as highly polished as usual. Claws cleft, teeth subequal. Venation normal except 

 that the lower discal cell of the hind wings exceeds the upi er and in some ■speci- 

 mens the intercostal vein is wanting ; stigma gradually tapering from near base to 

 apex. Sheath elongate, straight above, regularly rounded at the apex, hairs rather 

 long. Cerci not as long as sheath, not tapering. Black : legs below middle of 

 femora brownish-femigmous ; apices of tarsi dusky. Wings hyaline, iridescent; 

 venation light brown, costa and basal half of stigma pallid. 

 Male. — Unknown to me. 



Habitat. — Canada (Prov.) ; Ithaca, N. Y. 



The above description was drawn up from two females received 

 from Dr. A. D. MacGillivray. 



C. niger resembles salicicola E. A. Sm. but is quite distinct. 



13. Cryptocampus brachycarpae (Rohwer). 



Eniira hrachycafpir Roh., Can. Pint., xl. No. 6, June, 1908, p. 176. 



Female. — Length 5-5.5 mm.; length of the anterior wing about 5.5 mm. 

 Head seen from the side not abruptly narrowed toward occiput, fvenly rounded in 

 front. Clypeus rather deeply, subangularly emarginate ; lobes broad, rounded at apex. 

 Antennal foveae large, broader below antennce, middle fovea deep, elongate, open at 

 the top. Ocellar basin bounded by sharply raised walls, the lower of which is the 

 higher. Frontal crest rather strong, with three lobes Interocellar furrow present, 

 not very strong; lateral ocellar furrows broad, but still sharply defined, extending 

 from occiput to antennal foveae. Head rather sparsely punctured. Furrow of middle 

 lobe of mesonotum distinct but not extending more than half its length. Third and 

 fourth antennal joints equal ; apical joint not strongly tapering, equal in length to the 

 preceding one. Mesopleurse shining. Claws deeply cleft, the inner tooth the shorter. 

 Venation normal. Stigma rounded on lower margin, broadest a little basad to middle. 

 Sheath rather broad, straight on upper margin, rounded at apex, hairs dense and 

 long. Cerci not as long as the sheath above not strongly tapering. Black : lower 

 margin of clypeus, labrum, mandibles, except tips, which are piceous, tegul?e, extreme 

 angles of pronotum sometimes, posterior and superior orbits sometimes, legs below 

 coxse, except line on femora beneath, and apices of tibiae and tarsi sometimes, rufo- 

 ferruginous. Apex of venter is in a few cases brownish. Wings hyaline, iridescent, 

 venation brown, costa and basal third of stigma pallid. 



Male. — In general the male is much like 'he female. These difterences are to 

 be noted : lateral ocellar furrows are not so strong ; the apical four joints of the an- 

 tennae are rufo-ferrtigiuous ; the frontal crest is not trilobate but is notched; the lower 

 discal cell of hind wings sometimes exceeds the upper ; the stigma is elongate, ob- 

 liquely truncate at apex ; the inner tooth of claw is shorter Procidentia rather small, 

 rounded at apex. Hypopygium large, rounded at apex. Length 4-5 mm. 



Habitat. — Florissant, Colo. (Roh.); Ute Creek, Costilla Co., 

 Colo., July 7, 1907, alt. 9000 ft. ( R. W. Dawson).
