ACCEPTA GROUP 



Hairless apical margin of clypeus moderately wide; mesoplem-on 

 with a short weak carina extending obliquely downward and backward 

 from the front end of its transverse groove; propodeum without or 

 posteriorly with a few erect hairs ; brush on inside of hind tibia usually 

 with a subapical interruption; last tarsal segment in the female 

 usually with two or several bristles beneath (these bristles absent in 

 all the other species groups except the coronata group) ; subgenital plate 

 of male narrowly tectate, the apex rounded. 



Male with frons usually with an obscure rufous spot near the upper 

 end of the eye (this spot absent in the other species groups); tibial 

 spurs of male blackish or dusky in the Nearctic species. Female with 

 head, body, and appendages ferruginous. 



This species group includes conflicta, blaisdelli, accepfa, and Ageniella 

 persimilis Banks 1931 and an undetermined species, both from 

 Mexico. Ageniella may a Banks 1931 is possibly the male of persimilis.

Male: Forewing 4.0 to 4.5 mm. long; bristles on flagellum large 

 enough to be conspicuous among the fine erect sense hairs. 



Black. Frons with an ill-defined rufous spot near the top of the eye, 

 sometimes subobsolete; flagellum dark brown beneath; wings sub- 

 hyaline, the apex weakly infuscate; fore tibia fulvous in front; seventh 

 tergite with a large whitish spot. 



Female: Forewing 4.0 to 8.5 mm. long; apical hairless margin of 

 clypeus widened medially into a weak tooth; clypeus weakly im- 

 pressed sublaterally so that the central half of its apical margin is not 

 distinctly set off from its lateral quarters; frons subshining, with fine 

 rather close punctures. 



Ferruginous. Wings pale stramineous, the hind wing sometimes a 

 little darker apically, the forewing with a brown band over the basal 

 vein and nervulus, and its apical 0.35 brown, this brown area including 

 a large subapical crescent-shaped hyaline area.
