This is a common and widely dispersed species in the Eastern 

 United States, and well known to all collectors. It varies some- 

 what in minor details of coloration, but on the whole is strikingly 

 constant in general appearance. The nearly equally distant eyes

 spur on the front tibiae is notable. 



The intricatus of Suffrian is undoubtedly identical, as shown 

 by a type sent by Dr. Taschenberg.

Black, lustre dull, prothorax with the side margin — more 

 widely in front — apical edge and three discal spots, fulvous; eyes 

 separated by their own vertical length or more in both sexes; 

 antennae very elongate with linear joints, predominantly black; 

 front without ocular lines; front claws not at all enlarged in the
