and having the elytral interstices raised into narrow 
costse.

So similar to O. Americanus of the Atlantic States of 
North America, that a minute comparison has revealed 
no other points of difference than the finer punctate-stria3 
of the elytra, and the longer and more tapering shape of 
the dilated third joint of the anterior tarsi in the $ .

A very elongate, parallel-sided species ; wholly deep 
black. The antennas and palpi are longer and more slender 
than in O'u. helopio'ides. The thorax is a little broader 
than the elytra at the base, arcuated, elongated, and 
gradually narrowed to the apex ; the upper surface quite 
smooth, except the fine dorsal line. The elytra are very 
elongate and parallel, finely striated ; the stria3 very minutely 
punctulate, and the interstices quite plane. The third 
dilated joint of the $ fore tarsi is rather narrower and much 
longer than the second. Beneath the body is shining 
black, with the sides of the breast and abdomen faintly 
pimctulate. The prosternal ])roccss advances as a thick, 
obtuse wedge beyond the anterior coxro, and its upper sur- 
face has a very fine, well-defined rim.
