DR. F. LEUTHNER ON THE ODONTOLABINI, 425 
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 
tibiz 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 NV. 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 tibia 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 l’Abbé 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 NV. 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.
