 Mesonotum bearing large distinctly separated punctures 

 which are much closer together; scutellum with the 

 punctures smaller and not so deep, and almost absent in 

 the centre. Median segment with a wide furrow in the 

 centre in which are a few stout transverse keels ; on 

 either side of this it is irregularly punctured and has 

 some curved striae. Propleurae shining, strongly de- 

 pressed obliquely in the centre ; mesopleurae strongly 

 punctured all over, and without a distinct longitudinal 

 furrow; metapleurae almost impunctate and more shining 

 than the mesopleurae. Wings hyaline, the costa and 

 stigma black, the other nervures not so deep in tint ; 

 the recurrent nervures received shortly in front of the 

 transverse cubital. Abdomen thickly covered with white

Long. 7 — 8 mm. 



Hab. Barrackpore (Rothney). 



Resembles P. orientate, but has the body more thickly

 the middle, the appendicle of the areolet as long as the 

 cellule itself, and the recurrent nervures are received at 

 a greater distance from the transverse cubitals. 



Head closely and rather strongly punctured, more 

 closely and hardly so strongly behind the ocelli ; the 

 front and vertex covered with long fuscous hair ; from 

 the lower part of the eye incision to the apex of the 

 clypeus thickly covered with longish silvery hair, which 

 hides the sculpture entirely ; the apex of the clypeus
