clypeus is of a totally different form, being considerably broader 
and more deeply emarginate ; and, finally, the mandibles interiorly 
are strongly excised at their base. I have much pleasure in 
dedicating this species to James Thomson, Esq., of Paris, the 
well-known American entomologist.

Through the kindness of Mr. James Thomson, who has placed 
at my disposal for examination several interesting types of species 
belonging to the late Count Dejean’s Collection, as well as of 
others lately described by himself in the Catalogue of Lucanidz 
and forming part of his own rich collection, I am enabled to 
clear up many points of interest with reference to the synonymy 
of certain species. As regards D. Axis , there can be no doubt, 
as already noted by Dr. Burmeister (vid. Handb. v. 385), that it 
is the var. minor of D. Bucephalus 8, Perty, also from Java; but 
I do not feel disposed to agree with M. Reiche (vid. Ann. Soe. Ent. 
Fr. Ser. 3, i. 79) as to its identity with D. eurycephalus, Burm. 
Handb. v. 387, the description of the following characters in the 
Jatter species exhibiting such a marked difference from D. Amis as 
to render the identity of the two species most improbable. They 
are as follows:—the mandibles are described as forked at the 
apex, and armed interiorly with two to three teeth placed at sepa- 
rate intervals, the interior sides clothed partially with a thick silky 
pubescence (as in LZ, Sazga), and the antennz want the two slender 
hairy filaments preceding the clava, which are prominently to be 
recognized in D. Aais, Titan, Saiga and other species of this group. 
M. Reiche (ubi sup.) is probably correct in regarding D, eury- 
cephalus, Burm., as identical with Z. Bubalus, Perty. This latter 
species is referred to by Burmeister as the var. min. both of 
D. Bucephalus and of D. Saiga (vid. Handb. v. 385, 388). I have 
not seen the type specimens of either Bubalus, Perty, or Euryce- 
phalus, Burm., and feel doubtful whether they are a distinct species, 
or only the var. min. of one of the allied species. 
M. Reiche further states the 9 of D. Axis to be D. exaratus, 
Dej. Coll. Count Dejean’s specimen of the latter now belongs 
to Mr. Thomson's Collection, and was lately described by that 
gentleman in his Catalogue of Lucanide, p. 426; it is now before 
me, and is clearly identical with Dorcus lineatopunctatus 
of Mr. Hope’s Collection, described in his Catalogue, p. 23;
