It has seldom happened that so much confusion has arisen in consequence of 

 describing a female, as in the case of Olivier's Lucanus lama. Burmeister, as Parry 

 has shown ^, erroneously referred a number of totally different species (of true Lucanids) 

 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 (PI. LXXXV. 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 N. laiim ( cj ), 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 3 millim. long, projecting outwards, one near the tip, and 

 the other near the base of the mandibles ; mentum longer than in N. 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 N. lama (without the two vertical teeth), and with six teeth on the 

 inner side. It may be distinguished from N. lama by the longer and more quadi-ate 

 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 ;
