? . Clypeus broad, truncate at tlie apex. Eyes almost 

 parallel on tlie inner margin, separated on tlie vertex by a 

 distance about equal to the length of the second joint o£ tlie 

 flagellum ; posterior ocelli as far from each other as from 

 the eyes. Front rather flat; second joint of the flagellum 

 as lojig as the first and third combined. Pronotum in the 

 middle a little shorter than the mesonotum ; the posterior 

 margin arched, notangulate. Median segment much broader 

 than long, the posterior slope oblique, a longitudinal sulcus 

 on the dorsal surface. Fore tarsi with a long comb, the

 Tarsal ungues with one tooth near the middle ; hind tibise 

 spinose. Second abscissa of tlie radius a little shorter than 

 the first ; second cubital cell receiving both recurrent 

 nervures, the first a little before the middle, the second

The markings consist of short hairs laid very flat and close, 

 much as in " Pompilus " hihilis, Sm., from which the 

 neuration differs conspicuously, through the absence of a 

 third cubital cell. The structure is very similar to that of 

 A. cingulatus, Fabr., also the shape of the second cubital 

 cell.
