﻿48 Major Parry's Catalogue 



clypeus is of a totally different form, being considerably broader 

 and more deeply emargiiiate ; and, finally, the mandibles interiorly 

 are strongly excised at their base. I have nuicli ])leasure 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 LucanidcC 

 and forming part of his own rich collection, 1 am enabled to 

 clear up many points of interest with reference to the synonymy 

 of certain species. As regards D. Axh $ , there can be no doubt, 

 as already noted by Dr. Burmeister (vid. Handb. v. 38.5), that it 

 is the var. minor of D. Bucepliolus $ , Perty, also from Java; but 

 I do not feel disposed to agree with M. Reiche (vid. Ann. Soc. Ent. 

 Fr. Ser, 3, i. 79) as to its identity with D. eurycephahts, Burm. 

 Handb. v. 387, the description of the following characters in the 

 latter species exhibiting such a marked diflPerence from 1). Axis 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 sej)a- 

 rate intervals, the interior sides clotiicd partially with a thick silky 

 pubescence (as in E. Sai<^a), and the antenn;i: want the two slender 

 hairy filaments preceding the clava, which are prominently to be 

 recognized in D. Axis, Titan, Saii^a and other species of this group. 



M. Reiche (ubi sup.) is prol)abIy correct in regarding D. cury- 

 ccphalus, Burm., as identical with L. Babalns, 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 Buhalus, Perty, or Eurycc- 

 plialus, Burm., and feel doubtlul whether they are a distinct species, 

 or only the var. min. of one of the allied species. 



M. Reiche further states the $ of D. Axis to be D. cxaratus, 

 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 Lucanida?, p. lUC) ; it is now before 

 me, and is clearly identical with Durcus liiicaloputictalus ? 

 of Mr. Hope's Collection, described in his Catalogue, p. 23 ;
