Large or very large species of average stoutness, the Nearctic 

 species with the fore wing 13 to 48 nun. long; clypeus rather large, 

 often long; maxilla anthophilous; pronotum rather short, its hind 

 margin arcuate; apical end of marginal cell separated from costal 

 margin of wing, the cell rounded apically (the apex of this cell is 

 adjacent to the wing tip and pointed or subtruncate in the other 

 Nearctic Pepsinae); second intercubital vein moderately curved or 

 sinuate; second recurrent vein reaching the second cubital cell near its 

 basal 0.2; cubital vein reaching the wing margin; base of first discoidal 

 cell coutauiing a moderately distinct subcircular irregularity in the 

 membrane; nervulus beyond the basal vein by about 0.35 its length; 

 nervellus ending far beyond the juncture of cubitella A\ith discoidella; 

 anal lobe about 0.8 as long as submediella (pi. 1, fig. 2); hind tibia 

 with a strong dorsal serration ; brush on inner side of hind tibia broad, 

 without a subapical constriction; last tarsal segment with two regular 

 rows of bristles beneath; tooth on tarsal claws subbasal, pointed. 



Pepsis is restricted to the Western Hemisphere, where it is repre- 

 sented by several hundred species in the Neotropics and fourteen 

 species in the southern parts of the United States. Many of these 

 fourteen are widely distributed south of our border and reach their
