Mar.,iso9J ROHWER : CrYTOCAMPUS IN BOREAL NORTH AMERICA. 11 



these two species might prove them distinct. The d^ variety recorded 

 by Norton (p. 49, Trans. Am. Ent. Soc, i, 1867) is probably a dif- 

 ferent species. I know of no Cryptocampus which is black above and 

 pale beneath, but there are many Pontanm colored like his variety. 

 It is quite possible that Dr. Ashmead has mistaken behbiancB Roh. for 

 orbitaUs Nort. If such is the case orbUalis does not, as far as is known 

 at present, occur in Colorado. 



The above description is drawn from two females received from 

 Dr. MacGillivray. They were collected in New York state. 



2. Cryptocampus orbitalis var. niger (Norton). 



Enura orbitalis Nort. var. nigra Norton, Trans. Am. Ent. Soc, i, 1867, p. 71- 

 Cryptocampus orbitalis var. niger Dalla Torre, Cat. Hym., i, 1894, P- 277- 

 Cryptocampus orbitalis var. niger Konow, Genera Insectorum, p. 51, 1905- 

 F,„,ale -"A female from Labrabor has the whole head, except the mouth, 



black ; the cox«. and femora, except at tip, black ; the trochanters white" (original 



description). 



Habitat. — Labrador. 



This is undoubtedly a distinct species. In the black head it is 



like niger Prov., but has differently colored legs than that species. 



3. Cryptocampus cooperae (Cockerell).

 Enura coopercr Ckll., Ann. and Mag., Ser. 7, Vol. vii, p. 357, April, 1901. 

 i^.^.^/.. -Length 5 mm. ; length of anterior wing 5 mm. Head similar to 

 orbitalis Nort., but not so broad at the occiput. Clypeus deeply, angularly emargi- 

 nate ; lobes broad, obtuse at apex. Middle fovea deep, rather elongated. Antennal 

 foveee circular, deep, large. Ocellar basin large, broader below, bounded by low, 

 line-like walls. Interocellar furrow wanting ; lateral ocellar furrows rather sharp y 

 defined, extending to the antennal fove^. Frontal crest rather prominent, strongly 

 broken in the middle by the middle fovea. Third and fourth antennal joints equa ; 

 apical joint slightly longer than the preceding one. Head around the ocelli finely 

 punctured. Claws deeply cleft, the inner tooth much shorter, giving them the ap- 

 pearance of having a large middle tooth. Venation normal, except that the ower 

 discal cell of the hind wing is shorter than the upper ; stigma rounded on the lower 

 margin, tapering to the apex. Sheath broad, very obtuse at the apex straight on 

 upper margin. Cerci about the same length as the sheath above. Black ; head, 

 except behind, and a large spot enclosing ocelli (this black spot alinost touches the 

 inner eye margins, and does touch the occiput), pronotum, tegulse (the tegul^ are 

 sliehtly pallid), abdomen beneath and the apical dorsal segments, legs entirely, /.r- 

 rtinoHS. The head and pronotum are slightly brownish. Apical antennal joints 

 ferruginous, but not strongly so. Wings clear hyaline, iridescent, venation pale 

 brown, costa and basal half of stigma white. 



Habitat. — Las Vegas, N. M. (Mary Cooper).
