The elytra of this insect are not shorter than the hind body. 
The most striking character lies in the shape of the prothorax, 
that segment increasing in width only gently from the front to 
about the middle, but thence nearly to the base being much more 
strongly and more abruptly dilated ; the sides, however, owing to 
the strong curve of their hinder part are convergent close to the 
base. 
Compared with WV. Fortnumi, Hope, the principal differences 
(apart from colour and markings) are as follows :—-The head is 
not concave, and its sculpture is not at all longitudinal; the 
prothorax is differently shaped, and is very much more closely 
and strongly punctured; the elytra are distinctly less coarsely 
sculptured.

This species is very like the preceding, and I have felt some 
doubt as to whether its differences might be merely sexual, but I 
do not think this can be the case. It is a shorter and wider 
insect, with the apical ventral segment differently shaped, and all 
the ventral segments differently sculptured. These characters 
are very likely to be sexual, but in addition the colour is widely 
different, the whole sculpture of the upper surface is more 
rugulose, the outline of the prothorax is different, and the front
