Oss. This subgenus differs from Omaseus in having the elytra emarginate at the apex and the 
middle tooth of the mentum simple instead of emarginate. It approaches also to Platysma 
nigra in affinity, and has some relation to Cephalotes Bon. (Broscus Panz); but this is much 
less remarkable than the former affinity.

Oss. This insect, of which a wretched figure is given by Olivier, is the largest and hand- 
somest of the Javanese ddephaga. A piceous variety in my father’s collection is the very 
specimen from which Olivier took his description and figure. Its identity, therefore, with the 
above species is completely ascertained, and its nigropiceous colour in all probability merely 
results from its having been a young insect when taken.
