Described from a 6 in the Indian Museum from Kurseong, 

 27. vi. 1910 (Aamiiul(cJe). 



This is probably Bezzi's bisctosiis, but I do not like to sink it 

 definitely until further specimens of both species have been 

 compared.

* In my note on this species {vide I, c.) it was erroneaiisly stated that the 

 antenniB were missing, as on closer inspection it is fonnd tliat one of them is 

 still wholly intact, though pressed closo against the somewhat damaged head.
