KEVISION OF GENUS CUPHOCERA REINHAED 65 



the row; third antennal segment about one and one-half times as 

 long as wide ; otherwise very similar to male. 



Length, 9 mm. 



Remarks. — Redescribed from one male and one female in the 

 United States National Museum, from Verrugas Canyon, Peru, 5,500 

 feet, July 2, 1913 (C. H. T. Townsend). The type locality is Man- 

 tucana, Peru; type, female, in the Experiment Station collection, 

 Lima, Peru. 



The species resembles hirsufa but is readily distinguished by the 

 strong bristles on the middle of the cheek, wider front, and three 

 marginal scutellar bristles. There are other minor differences.

 widening rapidly to base of antennae; parafrontals largely shining 

 black, gray pollinose below and at outer corners of vertex; median 

 stripe yellow narrowed toward triangle, where it is less than half 

 the parafrontal width; ocellar bristles absent; verticals two large

 arranged in two rows, which diverge strongly beneath base of an- 

 tennae, descending below middle of second segment, uppermost three 

 bristles in the main row reclinate, the remainder directly inward; 

 face noticeably bulged at middle, silvery pollinose, in profile concave 

 above the mouth which is strongly protuberant; facial ridges flat 

 and bare ; paraf acial with two stout bristles on lower part and black 

 hairs extending upw^ard to lowermost frontals; cheek silvery polli-
