 cell narrowly roundoil at the apex, the cubitus of the hind

 two apical tlorsal sej^nients are carinated laterally and pro- 

 duced into aeute teeth at the apical angles ; the apical seg-

There is a female in the Britisii Museum collection from 

 Nasik, W. India, in which the wings are fusco-hyaline.

Ildb. Coimbatore, S. India; July. 



This species is distinct from rugosus, Cam., in which the 

 hind tibuT? are unarmed, the pygiciial area different in sculp- 

 ture, and the distribution of the yellow markings very 

 different. It also appears to be quite distinct from erythro- 

 poda, Cam. I only know Cameron's two species by the 

 description. N. violaceipennisj Cam., is a very distinct 

 species.
