 very pi'onounced on the first and reduced to a small patch on the third ; 

 venter with interrupted white bands on the second to f(Hirtli segments.

 of this species. They show that the naiiowing of the first postoi-ior cell 

 at the border is a variable character ^ — one specimen has it harely cIosimI
