comparatively smaller, canthus broad, triangular, under-surface of the head dull, 

 cheeks much more finely punctured, mentum thickly clothed with brown hair; 

 mandibles dull, forked at the tip, with eight teeth on the inner side; prothorax 

 shaped as in K swinhoii, but much narrower in front, which renders the sides oblique 

 as far as the rounded middle projection, behind which they are slightly emarginate; 

 hinder border nearly straight, pointed at each side. Prosternal process nearly obsolete, 

 elytra similar in shape and convexity to N. swinhoii, but varying from dark chestnut- 

 brown to black ; from the shoulders runs a pale brown border, about 21 millim. broad, 

 resembling that of Odontolabis sinensis. Recurved rim of the elytra as well as the legs 

 black ; front tibiae narrow as in N. sivinhoii, with four spines above the terminal fork.
