2 3 ORIENTAL ENTOMOLOGY.
tuft of ñdvous hairs at the tip within ; the elytra, under a lens, are very delicately punctiu'ed, and the mentum is
somewhat semieii'cular. Length of the insect, including the mandibles, very neai-ly 1 inch.
OBSEEVATION.—Tliis species belongs to the sectiou eontainiiig Luc. omissus, Hope, foveatus H.,
Astacoides H., &c.; and comes nearest to L. Mac Clellaudi H. (Ann. Nat. Hist., xii. 364, and
Cat. Lucan, p. 13), from "wliicli I find it, however, distinct. It is named iu honour of Major F. Jenkins,
by whom it and numerous other fine and new species have been kindly commiuiicatcd from Assam.
F I G U R E 4. LUCANUS OCCIPITALIS. HOPE. (CAT. LDCAN, COLEOPT. p. 13.)

bimaculato, occipite cai-inis duabus brevibns cui-vatisnigi'is,mandibuhsmagnitudinev-ai'iis, ocuhs dimidiatim septatis ;
prothorace capite angustien margine tenui, macula disci angulata, alterisque duabus versus ángulos posticos nigi-is,
eorpore subtus pedibnsque luteo-castiineis, tibiis linea supra nigra ; auticis extus subserrulatis, 4 postieis in ¡^
inermibus (vel interdum intermediis spina mmima mediana) ; in $ singula spina minuta media armata.
Fierama capite mediocri mandibulis, marginibus et macidis protlioracis suturaque elytrormn nigris.
Lucanus orange-clay coloured ; mth the head large, having an angulated tubercle on each side behind the eyes
(which are half-dii-ided by the septum), the front mai'gin of the head very much excavated, with t^^'o blade spots
near the base of the mandibles, and two angulated slightly msed black carince on the crown ; the mandibles varying
in form, prothorax narrower than the head mth a slender mai-gin, and a blacli diamond spot in the middle and two
small ones at the sides ; body beneath, and legs, chestnut clay-colora-, the tibiie with a black Ime, the fore ones subserrated,
the fom- hind ones in the male unanned (or the middle ones vith a very mhnite spine) ; in the female each
with a small spine in the middle. The female has a moderate-sized head, with short mandibles, which, as well as
the margins and spots of the pronotum, and the sntui-e of tlie elyti-a, are black.
Length of the insect, including the mandibles, from lOi to 17 hnes.
Inhabits the Phillippiue Islands (Cuming). In the Collections of the British Museum, Entomological Society, Hope, &e.
OBSERVATION.—This species, with several others from the Eastern Islands and from western
tropical Africa, form a distinct section, which ]Mr. Hope has named Prosopocoilus. There is much
difi'erence iu the form of the mandibles of the male iu the species before us : the largest specimen I
have seen, iu the British Museum, has them nearly | of an inch long, with a strong tooth before,
another compound one beyond the middle, aud a bifid apex; another, in Mr. Hope's Collection, has
them rather shorter than the head, with a small tooth near the base, another before the middle, and
three small subapical ones, whilst in the specimen figiu-ed they are short aud internally, irregiüarlv, aud
obtusely subserrated.
