INDIA :—Catcutta. 
A very distinct species, characterised by the rudimentary 
wings, black elytra, which are broad but short, round pronotum, 
and the form of the last abdominal segment and forceps. 
There is a larva with long segmented cerci which, on account 
of the distribution of colours, I attribute also to this species. It 
also comes from Calcutta.

INDIA: Drxrane Vauttey, Nananes. No. 5313/14. (Godwin- 
Austen). 
_ This is a very distinct species, characterised by the occipital 
sutures, the form of the pygidium, and the dilated abdomen. 
The basal part of the abdomen is badly broken, but the speci- 
men is apparently a female, though the well developed characters 
would appear to be more suitable toa male. It is possibly a male.
