separated ; eyes large, emarginate ; clypeal foveae deep ; body clothed 

 with fine short pubescence. 



Thorax fulvo-fuscous ; mesonotum fuscous ; mesopleurae with a 

 glabrous area just below the base of the wings ; metathorax slightly 

 hollowed behind, with weak anterior transverse carina, in front of 

 which the surface is smooth, behind with median longitudinal carinae 

 from which others run out and down. 



Wings hyaline, slightly tinged with fulvous ; stigma fulvous ; ner- 

 vures fuscous to black ; radial vein with its basal half thickened and 

 angularly broken 2 mm. from the stigma; discocubital vein bent; 

 nervulus antefurcal to interstitial ; nervellus broken far below the mid- 

 dle ; first recurrent vein three-fourths as long as the second. 



Legs fulvous ; abdomen with the two basal segments fulvo-rufous, 

 the remaining segments black. 



Described from two female cotypes. 



Cotype. — 9 . Chauchamayo, Peru, U. S. National Museum ; 

 9 , Pozuzo, Peru, U. S. National Museum, 



This species is related to flavohiscus Br. but is darker 

 colored and the fuscous on the abdomen of flavohiscus is here 

 replaced by black ; while the body is rufo-fuscous instead of 

 flavous as in the latter. This may be only a subspecies of flavo- 

 hiscus but appears to be a good species with the characters 

 well fixed. In one of the cotypes most of the head is fuscous. 



Distribution. — Chauchamayo, Pozuzo, Peru. It probably 

 ranges farther north and south.
