In both sexes the maxillary palpi are six-jointed, the joints 

 usually subequal, and the labial palpi four-jointed. 



In the female the shape of the second cubital cell is similar to 

 that of the male, but the neuration does not quite reach the outer 

 margin. The mandibles are strong and rather blunt, not biden- 

 tate. The epipygium is large and broad, usually pubescent. 



In both sexes the clypeus is very short, transverse. The 

 second and third cubital cells each receive a recurrent nervure in 

 most of the species, but in A. crassicornis Sm.((J) and A. clypeata 

 Sm.(9) both recurrent nervures are received by the second cubital 

 cell. 



The genus may be distinguished from the rest of the Scoliidcn 

 by the first abdominal segment, which is not strangulated in 

 either sex. It has a wide range over the Southern Hemisphere, 

 occurring in S. America, S. Africa, and Madagascar; but the 

 species seem more numerous in Australia than elsewhere.
