It has seldom happened that so much confusion has arisen in consequence of 
describing a female, as in the case of Olivier’s Zucanus lama. Burmeister, as Parry 
has shown}, erroneously referred a number of totally different species (of true Lucanide) 
to it. I entirely agree with Hope and Parry in regarding it as a female of the present 
species. 
The smaller the specimens the narrower they become in proportion, and the smallest 
of both the male and female forms (Pl. LX XXYV. fig. 12), which Hope considered to be 
a distinct species, and named Lucanus angulatus, are remarkably unlike the large ones.

Male. Very similar to the last species. .Prothorax rather broader in the type, but of 
about the same breadth as in WV. Jama (), in a second specimen of the same size in 
the British Museum. The only differences are in the mandibles. On the under- 
surface they are straighter, flattened, and not curved outwards. On the upper side 
they are rounded, with four or five teeth at the tip; besides these there are two large, 
round, straight teeth, 2 or 5 millim. long, projecting outwards, one near the tip, and 
the other near the base of the mandibles; mentum longer than in WV. lama, somewhat 
emarginate in front, and more hairy; the labrum is straight, and entirely fills up the 
space between the mandibles; it is clothed with brown hair in front; prosternum 
transversely carinated in front of the prosternal process. 
Priodont form (in British Museum). Mandibles rather longer than the head, very 
like those of WV. lama (without. the two vertical teeth), and with six teeth on the 
inner side. It may be distinguished from WV. Jama by the longer and more quadrate 
mentum. 
Female (?). Very similar to that of the last species, but larger and broader, entirely 
pitchy-black ; prothorax, elytra, and whole under-surface shining ; head and mandibles 
dull; head twice as broad as long, strongly convex, front edge strongly emarginate;
