rounded. The apical margins of the first and second segments

RHAGIGASTER COMPARATUS. 



Male. Length 5 lines. Black: head and thorax coarsely 

 rugose ; the abdomen closely punctured, each segment with an 

 oblique shining impunctate raised space on each side ; the two 

 apical segments ferruginous, and not so closely punctured as the 

 preceding ; covered with a scattered griseous pubescence ; the 

 wings hyaline, the nervures black ; the tibiae and tarsi obscure 

 ferruginous ; the segments of the abdomen constricted.

This species very closely resembles R. hamorrhoidalis ; but in 

 that species the apical margin of the terminal segment of the 

 abdomen is deeply emarginate in the middle, in the present 

 species it is rounded and entire ; the legs are also of a different 

 colour.
