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 WV. 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 V. swinhoii, but varying from dark chestnut- 
brown to black; from the shoulders runs a pale brown border, about 22 millim. broad, 
resembling that of Odontolabis sinensis. Recurved rim of the elytra as well as the legs 
black ; front tibiz narrow as in WV. swinhoii, with four spines above the terminal fork.
