disappeared. The elytra are coarsely punctured marginally, espe- 
cially in small males. 
The clypeus of the female is very broad with concave anterior 
margin. The sloping anterior part of the head, which is lightly 
concave, meets the horizontal posterior part at a distinct angle. 
The pronotum and elytra are coarsely punctured at the sides, 
more finely above. In the female from Reng Dung, which belongs 
to the Bombay Natural History Society, the anterior part of the 
head is less markedly concave than in the Himalayan specimens. 
The male by which it is accompanied is of the small form in which 
the dorsal tooth on the mandibles is not developed.

The clypeus of the female is narrower than in the preceding 
species. The separation of the anterior and posterior parts of the 
upper surface of the head is less abrupt. The punctures of the 
pronotum and elytra are much coarser and tend, even on the inner- 
most ridge of the latter, to fuse together so as to produce a general 
rugosity of the surface.

The female of this species closely resembles that of the last. 
It is, however, even more closely punctured, the difference—which 
is never very great —being clearest on the pronotum.
