The species of this genus are cuneiform, narrow, fuscous and covered with 

 a dense sericeous brown pubescence. The scutellum is rounded triangular, 

 the anal style is moderately long ; the hind tibiae have no subapical ridge, 

 (which exists in all the other genera,) but are carinate along the dorsal line, 

 and furnished with a long oblique ridge on the outer surface, which is con- 

 nected with the dorsal ridge near the tip ; the first joint of the hind tarsi has 

 two oblique ridges. The eyes are coarsely granulated ; the antennae are feebly
