the genae are more inflated and rounded, the clypens is more 

 attenuate laterally and more obtuse at the tip, which is also a 

 little more recurved, the cephalic liorn is more broadly laminate, 

 less attenuate towards the median part of the length, and curves 

 more strongly forward from that point ; the rest is as in O. ebenus. 



In both this and the preceding species the punctures or the 

 granules are occasionally less numerous in the second interval than 

 in the others.
