(>. aires, Fabr., with 0. carinafns, Linn. He considered 0. siva and 0. vishnu, Hope, 

 to be only varieties of 0. hellicosiis, to which he also referred 0. cumhigi, Hope. 

 Parry, the leading authority on the Lucanidse, came nearer the truth in regarding 

 0. cimingi, Hope, as only a variety of 0. dux, Westw. ; he also ventured to refer 

 Petiver's insect to the same species. But he united 0. alecs, Fabr. and Olivier, with 

 O. carinatiis, 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 0. nJces, Fabr., and 0. dux, Westw. ; and as 0. dux, Westw., is only a very rare 

 form of 0. alces, Fabr., the latter name must ba retained for this species.

Male. Resembles 0. ina-qualis and 0. 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 0. (jazella ( 6 ) and 0. 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 tlie 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 tibia 

 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 ])rothorax dull, elytra with a satiny lustre. Head 

 very convex, canthus broad, as in 0. (jazella ? ; prothorax convex, similar to that of
