Hab. Delhi, {Rothney), 



Is very nearly related to P. Rothneyi, which it also 

 resembles in having the apex of the median segment sub- 

 concave ; but differs in the wings having the apex hyaline, 

 the cloud not extending to it ; the third cubital cellule is 

 much wider at the top, in the radial cellule being longer 

 and much narrower ; in the prothorax having the sides 

 convex, in its apex being transverse, not arcuate ; in the 

 scutellum being shorter, broader, and not much narrowed 

 towards the apex, and in the white spurs and base of hinder 

 tibiae, the tarsi, too, being much more thickly spined and 

 fringed beneath.

 converging a little at the bottom ; ocelli separated from 

 each other by a greater distance than they are from the 

 eyes, not forming a triangle. Prothorax shorter than the 

 head, gradually narrowed towards it, behind arcuate. 

 Scutellum gradually narrowed towards the apex. Median
