Long. (cap. axel.) 24 mm., rostr. 7, elytr. 11, lut. 10. 



The base of the rostrnm has a rather deep curved impression behind tlie antennal 

 grooves; the lateral sulci of the rostrum are deep and almost reach the antennal 

 grooves ; the sides of the prothonix are faintly angular in front of the middle ; the 

 punctures of the pygidium large, but smaller thau the interstices between them ; 

 eacli puncture bears an extremely short brush of hairs, which is visible only with a 

 strong lens and almost looks like a yellowish scale.

Differs from 0. gracilis sp. uov. in colour, in the less angular sides of the 

 prothorax, in the elytra being proportionately narrower at the base, in the form and 

 structure of the pygidium, structure of the under surface, and some minor characters.
