furrows are only visible with a good lens. It is much

EVANIID^. 



EVANIA. 



Only one species of this genus has been recorded from 

 Continental India — E. antennalis West, from Bombay. It, 

 and the two species here described, may be separated by 

 means of the following table : — 



1. (2) Legs and body entirely black ; metasternal process 

 widely diverging at the apex ; the front distinctly keeled 

 in the middle. E. antennalis West. 



2. (i) Legs and body not entirely black ; metasternal pro- 

 cess not widely diverging ; legs marked with white. 



3. (4) Thorax red ; base of flagellum white ; face with 

 two oblique keels running from the eyes, 



E. curvicarinata. 



4. (3) Thorax and base of flagellum black; face not keeled. 



E. albitarsis. 



EVANIA CURVICARINATA, Sp. nov. 



Nigra; facie alba, thorace riifo ; annulo antennarum, 

 basi tibiarmn trochanteribusqiie albis ; tarsis posticis fuscis, 

 basi albis ; alis hyalinis. ? . 



Long. 6-J mm. 



In coloration comes near to the Ceylonese E. erythro- 

 soma, but that differs from it in many respects, e.g., in 

 having the face longitudinally striated and keeled down 

 the middle, and in wanting the oblique lateral keels 

 found in the present species. 



Antennae stout, black ; the basal two joints of the 

 flagellum for the greater part white, except on the apex 

 of the second, which is black all round ; the third joint is
