Long. 4 lin. 



Eab. Mexico, Cuernavaca (Salle) ; Guatemala, Panzos (Champion). 



The strongly reflexed or upturned edges of the thorax from the basal peduncle 

 (commencing abruptly) round the angle to the middle of the sides is a character which 

 distinguishes this species from A. anthracinus and A. scutifer. A similar structure is 

 perceived in A. alcyoneus and the nearly allied A. placidus, Say, of the middle States of 

 North America.

Except in * being of rather smaller size, there is no apparent difference between 

 specimens of this species from Washington Territory and others from Central America.
