14 OrpeEr—COLEOPTERA. Sectlon—PENTAMERA. 
A specimen from Pachbon, Siam, collected by M. Mouhot, in the Museum of W. W. Saunders, Esq., F.R.S., 
agrees entirely with my type specimens from Upper India. Another specimen in the same Museum, collected 
also by M. Mouhot at Laas, differs only in having the dise of the pronotum entirely black, with the yellow 
lateral margin much narrowed behind the small black spot which is united to the dark dise of the pronotum.

This very striking species is at once distinguished by its great width. It is convex, but with the base of 
the pronotum and the scutellar region of the elytra considerably depressed in the centre. The head is convex, 
very delicately granulose ; the clypeus rounded in front, with the fore margin slightly elevated ; there is a slight 
round impression on each side near the base of the antenne, and a fine impressed line extends backwards from 
the same point. The upper side of the head is blood red, but beneath and at the sides behind the eyes it is 
black ; the antenne have the club chestnut coloured; the pronotum is very glossy, nearly impunctate on the 
dise, with the sides finely but sparingly punctured. The hind margin is considerably produced over the base of 
the scutellum. On the dise are nine small black round spots, four on each side, forming an oblique lozenge, 
and one in the centre behind the middle. The elytra are very glossy, the dise nearly impunctate, the shoulders
