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

 uniform rust) yellow, and in having the third joint of the antenna": 

 nearly threo times as long as its greatest width, whereas in 0. me-

A rather broad species. Antenna) rather stout, half the length 

 of the body; fourth 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 tho 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 in t< r 

 stices narrow and slightly convex. The penultimate segment of the 

 abdomen has a trapezoidal emargination at the apex.
