About eighty species of this genus have been described, all of uniform black or 

 rufo-piceous colour, and, as Dr. Horn justly observes, in many cases difficult to discri- 

 minate. Although characteristic of the American fauna, tropical and temperate, the 

 genus is not wholly restricted to the New World, several species being recorded from 

 widely distant regions, such as Abyssinia, the Malay Archipelago, and Australasia. 

 Most of the species obtained by Mr. Champion were found in sandy places, especially 

 about the banks of streams. 



I. Clypeus with the sides of the emargination broadly rounded.
