2362. Petalocephala hearsayi, sp. n. 



2 . Yirescent ; vertex as long as breadth between eyes, finely

 centrally longitudinally ridged ; pronotum with the disk sparingly 

 punctate, anteriorly and posteriorly coarsely and thickly punctate, 

 the disk slightly centrally longitudinally furrowed ; scutellum 

 obscurely irregularly striate ; tegmina thickly punctate, the claval

This species is allied to P. bohemani, Stal, of wliich the British 

 Museum apparently possesses an example collected by Dr. Hors- 

 field in Java. From this it differs by the much less sinuate 

 posterior margin of the pronotum and the less centrally furrowed 

 disk of same, the much more strongly centrally I'idged vertex, and 

 the more obliquely truncated apices of the tegmina. The speci- 

 men from Barrackpore in the British Museum I have fixed as 

 type.
