A remarkable similarity exists between O. Lcnvei and 
O. Brookeanus ; upon closer examination, however, the 
two species are found to be abundantly distinct. Unfor- 
tunately, but one specimen of O. Loxcei exhibiting a 
minor development of the mandibles has at present fallen 
under my notice, and having compared it with numerous 
specimens of O. Broohcanus exhibiting various degrees of 
development, the following differences are found apparent: 
The entire length of Lowei, 2^ inches, exceeds consider- 
ably any specimen of its allied species I have met Avith. 
The differences in form and sculpture of the mandibles is 
at once conspicuous ; instead of being semicircular, as they 
are invariably in O. Brookeanus, they are porrect, slightly 
curved from the base to the apex, much narrower, and 
with the upper surface more convex and covered with a 
dense granulation. The head is more elongate convex, 
Avith the anteocular angles rounded, not acute, and the 
entire surface thickly granulated. The prothorax is wider, 
with a black plaga, covering nearly the entire upper surface, 
leaving only a very narrow rufous line at the base, Avith a 
somewhat broader one at the sides ; the posterior angles 
are less emarginate, and the granulations are much denser. 
The elyti'a are moi*e elongate and narrower posteriorly, 
very glabrous, and of a deeper yelloAv colour ; the under
