margin. Elytra long, oval, upper side less convex, the shoulders straight, shoulder- 
angles acute, otherwise as in 0. latipennis. 
Female. Uniform deep black, head and prothorax dull, elytra shining. Head much 
broader than in 0. latipennis; canthus projecting more outwards, and broader ; 
mentum broader; prothorax broader, front edge strongly emarginate on each side; 
front angles acute, sides nearly straight; prosternal process flattened, finely pointed 
behind; elytra long, oval, upper side less convex than in 0. latipennis, but more so 
than in 0. camelus; shoulder-angles acute, outer margin strongly curved outwards in 
the middle; upper surface deep uniform black, in the middle shining, and on the 
sides dull. Front tibie longer than in 0. latipennis, narrow, with five spines above 
the terminal fork; the hind legs are also longer, and occasionally narrower, and the 
tarsi much longer in comparison than in 0. latipennis. All the tibie are narrower 
and straighter, and the punctuation is more granular.

I found examples of this species mixed with those of 0. alces from Manilla, not only 
in Herr Schneider’s consignment, but also in Herr van Lansberge’s collection. The 
striking difference in the females led me to treat it as distinct. Although the females 
are always very like those of 0. latipennis, they are still more closely allied to those of 
O. camelus from Mindoro. The two figures on the plate are unfortunately not so exact 
in outline as I could wish.
