8. Pepsis completa. B.M. 



Female. Length 10 lines. — Black : clothed with a green or 

 blue-green pilosity, four or five of the apical joints of the an- 

 tennae yellow ; the metathorax transversely striated, convex, and 

 rounded behind ; the wings dark rufo-fuscous, with a changeable 

 violet iridescence, and having a broad transverse, complete, yel- 

 low liand, crossing the wings about one-third from their base ; 

 abdomen bright blue-green. 



Hab. Brazil. 



This species is closely allied to the Pompilus dimidiatus of Fa- 

 bricius, from which it principally differs in the situation of the 

 band, which constantly extends further on the wings, and the 

 inferior wings are always black at the base.
