444 Major F. J. Sidney Parry's Remarks upon 



Mr. Thomson mentions 190 species in his collection, a very 

 large number, when compared even with the late Mr. Hope's, 

 whose catalogue contained 166 species, but from which a con- 

 siderable reduction is to be made. It may, however, surprise 

 some Entomologists to hear that of late years so numerous have 

 been the additions of new species to our collections, that I am in a 

 position to assert my actual knowledge of 322 species, nearly all 

 having been described, and of which my own collection possesses 

 276 species, the largest collection of Lucanoid Coleoptera, I be- 

 lieve, ever brought together; that of Count Mniszech is also of a 

 very vast extent, containing 255 species. 



With such a large amount of material, it is quite evident that 

 to prepare a satisfactory catalogue of the Lucanidce much patience 

 and consideration is required ; such a work, to obtain a successful 

 result, ought not to be hastily executed, and of this I am the 

 more convinced after analyzing the publication at present before 

 me. 



I now propose to take seriatim the various genera and species 

 to which I am desirous of referring. 



1. Chiasognathus Mniszechii, Thomson, n. sp. Chili $ . 



This fine pubescent species may possibly prove to be identical 

 with Ch'iasog. Jousselinii $ , Reiche, Chili, — a unique specimen in the 

 collection of Mons. Jousselin, at Versailles (vid. Ann. Soc. Ent. 

 France, torn. 8, p. 267). 



2. Chiasognathus Reichii, Thomson, n. sp. Chili $. 



This insect may probably be the $ of C. Latreillei 2 , published 

 in Gay, Hist, de Chili, Zool. v. p. 42. I may here remark that 

 Mr. Thomson, in describing the publication of this genus by Mr. 

 Stephens, as' appearing in the Philosophical Trans, o^ Canterbury, 

 instead of those of Cambridge, has probably copied this error from 

 Dr. Burmeister (vid. Handbuch dev Entomologie, p. 337). Solier, 

 in Gay's Hist, de Chili, has also committed the same inadvertence. 



3. Sphcenognathus Murrayi $, Thomson, n. sp. Venezuela. 

 rugosum. Parry, MSS. 



Mr. Andrew Murray, so intimately acquainted with the several 

 species of this sub-genus, had kindly undertaken the description 

 of this new species for our Transactions. 1 had long since pointed
