near tlie tip. Tlie four hind feet are robnst, -n-itli the tibiae strongly toothed in three separate series.
The claws in these feet arc formed as in those of the fore-legs. The entire under-siuface of the body is
brassy blacky thickly clothed with monsc-coloured hairs j the front margin of the liead is elevated,
sharp and shghtly denticulated.
The female, contrary to the nsual rule among insects, is smaller than the male, agreeing with the
latter ni general colours and appeai-ance, except that the wiug-covers are of a greeuer tinge, the sides
of the thorax not so much dilated, and the fore-legs of ordinary length, with broad flattened tibia;,
haAing at least five strong teeth (varying, however, in number on tlie opposite legs of the same
individual). lu the only specimen hitherto known of this sex, the anterior niargm of the head was
not symmetrical, the right angle being more porrected than the opposite one.
The unique male * of this insect was received in a splendid collection from the Himalayas during
the past summer, by H. G. Harrington, Esq., by whose direction an engrafting of the insect was prepared,
which has since been published in the Annals of Natural History, accompanied by a short note by
Captain P. J. Parry, into whose rich collection it has now passed. The female was described by the
Eev. F. ^Y. Hope, in the Linnaian Transactions (vol. xviii. p. 591,) from a uninue female collectMl in
Assam by W. Griffith, Esq., in the collection of R. H. Solly, Esq.
The outUne figure at the foot of the plate (fig. 3,) represents one of the lower jaws (maxillfe) of the
male, highly magnified; « being the cardo or basal hinge, d the stipes, of a triangular form; c the
squama palpifera; c * the mando terminated on the inside by a setose lobe; d the maxillary palpus;
e the galea or upper lobe of the maxillis, with short obtuse teeth fit for trituration rather t h m biting,
and terminated by a very long pencil of hair-, as in the stag-beetles.
OBSERVATIONS.—India and the adjacent islands offer to us a striking peculiarity in respect to the
geographical distribution of the gigantic species of LamelHcorn beetles. Whilst the New World
is inhabited by a great number of these fine insects, (of which Dynastes, Hercules, and Elephas may
be mentioned as weU-known examples) the tropical oriental regions can boast but of few t j these,
however, are distinguished by their metalhc or variegated appearance, of which their American brethren
are destitute. Thus, amongst the true Dynastidse we find Chalcosoma Atlas and its alhes, to which
we may add the fine species, Dynastes Hardwickii, and the singular species constituting the genus
Eucheii'us, which in several respects seem to be the oriental representatives of tlie Golofa; of the
New World.
This group of insects has much perplexed Entomologists as to its relations and consequent natural
position amongst the LameUicorn beetles. Fabricius, Olivier, &c., arranged it with the Dynastida;.
Mr. Hope, (Linn. Trans, xviii. 596) formed it into a separate family, Eucheiridse, which he considered
as " closely allied to the Dynastidae and forming a sort of connecting hnk with the Goliathida;."
Drs. Klug and Erichson, (Proceedings of Berlin Academy, 1839; Wicgm. Archiv. Bcricht, 1839, p. 38
(214); Taylor's Annals of Nat. Hist. No. 21, September 1839,) propose to place it at some distance
from the DjTiastidie and even after the genus Cyclocephala, approacliing Melolontlia; whilst
Dr. Bm-meister (Zeitschr. d. Ent. 2, p. 353, and Handb. d. Ent, 3, p. 698,) refers it to the Trichiidie.
* By information recently received from Captains Boys and Huttoii, and Dr. Benson, I am induced to bolieyo tliat otiicr specimens of
this insect, or of a nearly allied species have lately been found in India.
+ The stag-beetles (Lucanidio) seem to occur in a reversed proportion in these two parts of the globe : tlie oriental species far
exceeding, both in numbers and size, those of the New World. Thus Nature appears to restore the equilibrium by giving to each
district a certain number of species possessing analogous pi-operties. °
