446 DR. F. LEUTHNER ON THE ODONTOLABINI. 
O. alces, Fabr., with O. carinatus, Linn. He considered O. siva and O. vishnu, Hope, 
to be only varieties of O. bellicosus, to which he also referred O. cumingi, Hope. 
Parry, the leading authority on the Lucanidw, came nearer the truth in regarding 
O. cumingi, Hope, as only a variety of O. dua, Westw.; he also ventured to refer 
Petiver’s insect to the same species. But he united 0. alces, Fabr. and Olivier, with 
0. carinatus, Linn., a species which remained doubtful until very recently. In the 
first part of this paper (pp. 395-403) I have given conclusive evidence of the identity 
of O. alces, Fabr., and O. dux, Westw.; and as 0. dux, Westw., is only a very rare 
form of 0. alces, Fabr., the latter name must be retained for this species.

Male. Resembles 0. inequalis and O. latipennis in general appearance. Uniform 
black, head coarsely punctured, prothorax and elytra shining; mandibles strongly 
incurved, with four or five irregular obtuse teeth at the tip, separated by a gap from 
two small overlapping obtuse teeth at the base; upper side of the mandibles, in large 
specimens, channelled from the base to the tip; but this channel is much shallower and 
less conspicuous in small specimens. 
Dull, finely granulated, head broad, flattened as in O. gazella (3) and O. latipennis, 
but narrower behind; frontal edge nearly straight, and very slightly emarginate ; 
canthus broad before the eyes, but rapidly narrowing behind, the spine behind the eyes 
rather further from them than usual, and finely pointed, directed obliquely backwards 
towards the neck ; mentum hairless; front margin of the gula strongly swollen, cheeks 
with fine scattered punctures; prothorax slightly convex, very finely punctured, more 
than twice as broad as long, with a single pointed and very prominent lateral spine 
(this is obtuse in small specimens, which renders the prothorax apparently narrower) ; 
hind margin of the prothorax waved ; prosternal process strongly developed and pro- 
jecting vertically downwards; elytra scarcely broader than the prothorax, slightly 
shining, very finely punctured, and widened a little beyond the shoulders; front. tibie 
very long, narrow, nearly straight, slightly channelled on the upper side, the terminal 
fork slightly developed, with two slender spines on the outside in large specimens and 
three in small ones, which are but slightly developed, and project forwards. 
Female. Uniform black, head and prothorax dull, elytra with a satiny lustre. Head 
very convex, canthus broad, as in 0. gazella 8 ; prothorax conyex, similar to that of
