sides ; upper side dull ; mandibles short, shining, forked at the tip, and with six or 

 seven small teeth on the inside ; mentum thickly clothed with brown hair ; prothorax 

 broad, the front edge strongly emarginate, the sides very slightly convex as far as 

 the middle spine, which is rounded off; behind this the sides are slightly emarginate; 

 the hinder edge is waved ; prosternal process well developed, obtuse ; elytra of a long 

 oval form, rounded at the shoulders and at the tip, pale chestnut-brown, with a trian- 

 gular black spot commencing at the shoulders, and gradually decreasing and coalescing 

 with the narrow black borders of the elytra ; rim of the elytra black beneath ; front 

 tibiae narrow, with four or five spines on the outside above the terminal fork. 



Female. Resembles Neolucanus marginatus, Waterh. (fig. 3), and Odontolabis cuvera; 

 uniform black ; elytra bicolorous. 



Smaller and broader than N. marginatus, with the thorax and elytra more convex ; 

 head broad, flat, emarginate, and strongly shagreened in front, upper side dull, canthus 

 oblique and then rounded, nearly as broad as the eye ; mandibles short ; mentum with 

 a crescent-shaped crest, strongly shagreened and hairless; prothorax broad, dull, 

 strongly emarginate on each side in front, the front angles pointed, the sides slightly 

 convex, and broadest in the middle ; middle spine rounded, the sides behind it some- 

 what emarginate ; hind margin nearly straight, hinder angles pointed ; prosternal 

 process rounded, and rather pointed behind, carinated in small specimens ; elytra 

 remotely oval, strongly convex, and rounded at the tip; the black triangle which 

 begins at the shoulder rapidly narrows hindwards, and coalesces towards the tip with 

 the rather broad black border, which renders the intermediate yellowish brown stripes 

 linear; underside of the recurved elytra jet-black; front tibias long and narrow, with 

 four spines above the terminal fork ; underside of the femora with fine scattered hairs. 



Habitat. Province of Kouey Cheou, in China, collected by I'Abbc Largeteau ; Laos 

 (Siam), collected by M. Mouhot. 



One male (type), in the collection of M. Oberthiir, of Rennes ; two females (types), 

 in Major Parry's collection.

Two females of this species, from Siam, stood in Major Parry's collection for a long 

 time as females of his N. cingulatus. Shortly before the completion of this paper, I 

 received a male (unfortunately damaged), through the kindness of M. R. Oberthiir, of 

 Rennes, from a Chinese province further north than Siam. It reached me just in time 

 for the description to be here included, but too late to be inserted in the Plates, which 

 were already drawn on the stone. I cannot better express my thanks to Major Parry 

 for the many kindnesses which I have received at his hands than by naming this 

 interesting species after him.
