 pis testaceis. Long. corp. vix 2\ lin. 



Capite inter antennas 2-impresso, fronte leviter excavato, mandi- 

 bulis subtiliter sulculatis, mento preecedentis ; thorace robustiore, 

 ut in praecedente sculpto et signato, sed antice non strigoso ; elytris

 testaceis, pedibus flavis, trochanteribus, geniculis tarsisque obscu-

Specimina nonnulla mens. Decemb. prope Colombo nocte ad lumen

Smaller than the Ophionia cyanocephala. The head is robust, 

 with two impressions between the antennas, and a third just 

 above them, somewhat of the shape of an inverted V. Oc- 

 ciput less narrowed than in O. cyanocephala, smooth. The 

 anterior part of the head deeply punctured. The labrum is 

 slightly produced in the middle. Thorax much plumper than 

 in O. cyanocephala, hardly as long as the head, not much 

 narrower, conic, considerably narrowed and cylindric at the 

 base, densely and deeply punctured, especially at the base. 

 Elytra with the shoulders straighter than in 0. cyanocephala, 

 impressed with rows of deep punctures growing smaller and 

 shallower towards the apex, with a few small hairs near the 



* In the Distrigi just described, joints 3 and 4 are subequal.
