No. 2366. NOTES ON TIIE SUBFAMILY PERREY1IN AE—ROHWER. 165 



projection; head and thorax polished and with short gray hair; 

 stigma widest near base; third cubital on radius a little more than 

 half and on cubitus half the length of second; second recurrent inter- 

 stitial with second intercubitus ; hypopygidium broadly truncate with 

 rounded lateral angles. Black; anterior femora and tibiae and inter- 

 mediate tibiae beneath piceous; wings uniformly dark brown; vena- 

 tion black. 



Type locality. — Balzapamba, Equador. 



Described from a single male collected by R. Haensch. 



Type. — In the Deutschen Entomologischen Museums, Berlin. 



LOPHYROIDES FULVA (Moscary). 



Five males from two different but indecipherable localities in Peru 

 are assigned to this species. They differ from the brief description 

 given by Moscary in having at least a part of the thorax piceous, but 

 as there is considerable variation in the specimens before me it is not 

 considered advisable to treat these as a different species. In one 

 specimen the clypeus as well as the labrum is yellow, in the others 

 the clypeus is mostly black. 



Genus HETEROPERREYIA Schrottky. 



I do not know the genotype of this genus and have placed the fol- 

 lowing species in it largely because of the venation. The original 

 description of the genus makes no mention of the palpi, so I have 

 taken this character from the species here described. 



HETEROPERREYIA COSTATA, new species. 



In color and general appearance is, judging from the descriptions, 

 more closely allied to Brachytoma melanopyga Knoow, but may be 

 distinguished from that species by the yellowish wings, entirely black 

 head, pale tarsi, etc. It is not unlikely that this will prove to be the 

 female of Brachytoma nigriceps Westwood, but it differs from the 

 description of that species in the entirely black antennae, black 

 labrum, and uniformly pale thorax. 



Female. — Length, 10.5 mm.; length of anterior wing, 10.5 mm. 

 Labrum short rounded apically; clypeus flat, with sparse sctigerous 

 punctures, anterior margin broadly, shallowly arcuately emarginate; 

 supralclypeal area strongly raised almost tuberculiform; frontal crest 

 very prominent, slightly broken medianly; middle fovea very large, 

 deep, ellipical; lateral ocelli on low tubercules and directed laterally; 

 postocellar line distinctly shorter than ocellocular line and subcqual 

 with the ocelloccipital line; antennal furrows complete; postocellar 

 furrow curved; malar space distinct; antenna longer than the head 

 and thorax, 18-jointcd, flagellar joints narrowed at base beneath, 

 the first one-fourth longer than second, the following diminishing in 

 length to eight where they become subequal in length; thorax and
