 very near its apex, but not uniting with the transverse nervure. 

 Abdomen punctured, the apical margins of the segments having 

 fuscous fasciae, which are continuous and broadest on the venter. 



Male. Length 10 lines. Very closely resembling the female, 

 but the transverse stripe on the vertex is broader and emits a

 of the wings is different, and the abdomen is not punctured ; the
