( 197 ) XX. Descriptions of some new Species of Exotic Lucanidsc. By J. O. VVestwood, F.L.S., &c, [Read 5th February, 1855.] Having from time to time, since the publication of my memoir upon tlie distribution of the Lucanidce, in the Annales des Sciences Naturelles for 1834, made drawings and dissections of various re-markable species of that family which have fallen under my notice, and which have possessed characters of an interesting description with reference to the generical division of the family, I beg leave, on the present occasion, to offer them to the Entomological Society, as a suj)plement to the various memoirs on those insects by Messrs. Hope,* Parry, f Saunders, | and myself,§ which have appeared in the Transactions. SPECIES FROM SOUTHERN AFRICA. Genus Colophon, Westw. (Ann. So. Nat. 1834.) Of this curious type a single species has hitherto only been noticed, namely — Sp. 1. Col. IVeslwood'd. (Plate X. fig. 1, details.) C. Westwoodii, G. R. Gray in Griffith's An. King. ; Ins. p. 534, pi. 4G, f. 5 ; Westwood in Aim. Sc. Nat. 2d Ser. ; Zool. t. 1, pi. 7, f. 5, with generic details. Having had an opportunity of making a more minute examina-tion of the type specimen of this insect in Mr. Hope's Collection, I am able to add the following particulars, for the most part ren-dered necessary by the discovery of a second still more remark-able species of the genus acquired by Mr. Hope. The head is transverse, emarginate in the middle of the ante-rior margin, but with the clypeus slightly advanced over the labrum, which it conceals; it is furnished on the upper side with • Trans.
