triangular behind, is quite apical, and the truncate part may be 

 said to be its basal part ; the prothorax is deeply excavate from 

 the anterior margin to the base, and the walls of the excavation 

 which are very much raised are not quite vertical in front, and are 

 produced in the middle into a broad and sharp triangle the sides 

 of which have nearly the same slope, the cavity is closely punctured, 

 the punctures being almost contiguous, and the sides are covered 

 with moderately deep, not closely set punctures ; elytra covered 

 with deep, irregular, scattered punctures, and having four faint 

 dorsal striae, including the juxta-sutural one, all four of which 

 disappear past the median part ; valves of penis deeply emarginate 

 from near the base to the median part, not angular in the lower part 

 of the emargination, and with the forcipate part nearly straight from 

 there to the apex ; the inner part is deeply emarginate at the base. 



Female : Same colour as the male, although a little lighter, the 

 clypeal part is distinctly punctate and separated from the frontal 

 part by a somewhat evanescent bi-sinuate line ; prothorax simple, 

 somewhat closely punctate, but with the punctures a little less 

 numerous in the median part ; elytra as coriaceous as in the male, 

 although the punctures are not quite so deep, and with only one 

 discernible stria besides the juxta-sutural one ; the metasternum 

 has a slightly impressed longitudinal line as in the male. 



I am not quite sure that the female here described is that of 

 O. rufulus ; it is iQuch shorter, in proportion to the size, but it 

 comes from the same locality.

Female : Piceous, moderately shining ; head simple, closely and 

 distinctly punctate except for a narrow basal strip which is almost 

 impunctate, frontal transverse line hardly noticeable ; prothorax 

 simple, covered with small punctures very closely set except in the 

 median part where they are few, and having in the basal part 

 an elongate, sub-triangular, slight impression ; scutellum slightly 

 concave, ogival, punctate ; elytra with scattered punctures more 

 numerous in the anterior part, first and second striae distinct from 

 the base to the posterior rounded part, third and fifth also distinct
