Genus NiLAPAEVATA. 



Nilaparvata Dist., Faun. Brit. Ind. Rhynch. iii. p. 473 (1906). 



This genus was founded for the reception of a species from Ceylon. I am unable 

 to generically separate the following species, though the antennae are inserted at about 

 middle of eyes and not beneath them, while the venation of the wings is setigerous, 

 and the vertex not longer than broad.
