colouring begins to dilate and forms an elongate-oval spot 
extending to the apex and reaching laterally to about the fifth 
stria on either side. The clypeus is continuous with the hinder 
part of the head, which bears an elongate notch-like impression 
between the eyes. The prothorax is about twice as wide as long, 
its base nearly twice as wide as its front margin, sides straight, 
front angles acute, hind scarcely so. The interstices of the striae 
on the elytra are not punctured. The whole insect has a semi- 
opaque appearance on the upper surface, and is minutely 
coriaceous.

The clypeus is continuous with the hinder part of the head 
which is finely canaliculated longitudinally. The prothorax is 
two-thirds wider than long down the middle, its base a little 
wider than the front margin, the sides rather sti’ongly rounded, 
all the angles acute and pointed outward. The interstices of the 
strife on the elytra are very finely and moderately thickly punctu- 
late. The extent of dark colouring on the ventral segments is 
variable, being extended in some examples over more than the 
apical half.
