This species only differs from 0. melanunis in having the elytra 

 uniform rusty yellow, and in having the third joint of the antennae 

 nearly three times as long as its greatest width, whereas in C. me- 

 lanurKS it is at most twice as long as broad.

Hah. Nepal. 



A rather broad species. Antenn?e rather stout, half the length 

 of the body; foui'th joint as long as the two previous joints taken 

 together, the fifth a little shorter ; the sixth to ninth very slightly 

 increasing in length, very little compressed, truncate at their apex. 

 Thorax a quarter broader than long, moderately shining, the an- 

 terior angles are more rounded than the posterior ; the central im- 

 pressed line reaches from the posterior to the anterior margins, is well 

 defined and of equal depth throughout ; on each side are two largo 

 deep impressions, separated from each other by an oblique ridge. 

 The elytra are at the base a little broader than the thorax, a little 

 wider posteriorly, red, with a black (or bluish black) patch extend- 

 ing from the base to the posterior two thirds, leaving the margins 

 and the apex red ; each elytron has five impressed lines, the inter- 

 stices narrow and slightly convex. The penultimate segment of the 

 abdomen has a trapezoidal emargination at the apex.
