the ocellar basin scarcely indicated j antennce stout, rather short, covered 

 with a fringe of long seise, at the base of which are small protuberances, 

 giving the antennae a roughened appearance ; first segment twice as long 

 as the second, flaring at apex ; the second short, transverse ; the third and 

 fourth subequal ; the free part of Sc^ about twice its own length proximad 

 of the medio-cubital cross-vein ; stigma short, rather broad ; the radio- 

 medial cross-vein hyaline ; the cells R^ and R5 subequal in length ; claws 

 cleft, the outer ray longest ; colour black, except the legs beyond the 

 knees, four hind trochanters, and anterior femora on sides white, apex of 

 posterior tibi?e fuscous. 



Length, 6 mm. 



Habitat. — Farmington, Conn. (Norton.) 



Priophortis solitaris, Dyar. — 9 • Long) robust ; clypeus transverse, 

 densely covered with long set^e, deeply and roundly emarginate, with the 

 lateral angles prominent, angulate ; tentorial invagination prominent, 

 expanding into a large, prominent depression surrounding and extending 

 above the base of the antenna?, continuced as a broad concave depression 

 to caudad of the lateral ocelli, not breaking through the occiput, slightly, 

 transversely interrupted midway between antennre and ocelli, caudad of 

 the ocelli transformed into a deep line-like groove, the transverse groove 

 and the groove of the anterior ocellus hardly indicated ; the antennal 

 fovea large, broad, shield-shaped ; the antennal area long, narrow, pointed 

 at apex ; the frontal crest distinct, not interrupted ; the sides of the 

 ocellar basin indicated ; the antennse long and slender, narrowed to apex, 

 first segment twice a$ long as the second, flaring at apex, the second short, 

 transverse, the third and fourth subequal ; the free part of Sci about three 

 times its own length proximad of the medio-cubital cross-vein ; stigma 

 short, blunt, broadly convex on the caudal margin ; *the radio-medial 

 cross-vein almost completely hyaline ; the cell R5 distinctly longer than 

 cell R4J claws cleft, outer ray longest; cerci minute, inconspicuous ; saw- 

 guides prominently retracted, exposed portion pointed, concave on dorsal 

 and ventral edges before the apex ; colour black, except the legs beyond 

 the knees, which are white, with apices of the tarsi infuscated ; wings 

 infuscated, stigma and veins brownish. 



Length, 7 mm. 



Habitat. — Described by H. G. Dyar from a female bred from larvae 

 on Abius ; Franconia, N. H. (Mrs. A. T. Slosson) ; Ithaca, N. Y.
