Genus DIAMORUS Walker. 



This genus should occur in South America, but I have seen no representatives 

 of it in any of the collections examined by me. The species recorded and described 

 by Dr. Mayr as Diamorus resemble genuine species very closely, but they really rep- 

 resent the females of Mayr's genus Physothorax. 



Genus PHYSOTHORAX Mayr.
