100 Mr. T. V. Wollaston on certain Coleoptera 



Dermestes vulpinus, GyH-, Ins. Suec. i. 147 (1808). 

 . , WoU., Ins. Mad. 202 (1854). 



Several specimens of the cosmopolitan D. vulpinus were taken 

 at St. Vincent by Mr. Gray and the Rev. Hamlet Clark, during 

 their day^s collecting there, in December 1856. 



Fam. Histeridae. 



Genus Saprinus. 



Erichson, in Klug Jahrb. i. 172 (1834). 



12. Saprinus equestris, Erichs. 



Saprinus equestris, Erichs., in Wiegm. Arch. ix. 226 (1843). 

 , de Marseul, Ann. de la Soc. Ent. de France, 3 ser. 358 (1865). 



This elegant Saprinus was captured by Messrs. Gray and Clark, 

 in tolerable abundance, in stercore humano, near the sea-beach of 

 Porto Grande, during their few hours' sojourn at St. Vincent in 

 December 1856; and also in the same locality by my nephew, 

 F. W. Hutton, Esq., on the 11th of June, 1857. It is recorded 

 by De Marseul as occurring likewise at Angola and Benguela ; 

 but whether it is truly found there, or whether that " habitat " 

 merely rests on the authority of Erichson's paper, in which the 

 insects from Angola and the Cape de Verdes were indiscrimi- 

 nately mixed up, I cannot undertake to say. 



Fam. Elateridse. 



Genus Heteroderes. 



Latreille, Ann. de la Soc. Ent. de France, iii. 155 (1834). 



13. Heteroderes grisescens, Germ. 



Cryptohypnus grisescens, Germ., Zeitschr. f. d. Entom. v. 151 (1844). 

 Monocrepidiusl Grayii, WolL, Ann. of Nat. Hist. ser. 2. xx. 505 (1857). 

 Heteroderes grisescens, Candeze, Mon. Elat. ii. 377 (1859). 



A single specimen of this insect was found beneath a stone, 

 at some little elevation above the sea, by the Rev. Hamlet Clark, 

 during his day's sojourn at St. Vincent with Mr. Gray, in De- 

 cember 1856; and I have also two more examples now before 

 me, likewise taken in the island by Mr. Fry. In my short 

 paper on the Coleoptera collected by Messrs. Gray and Clark, 

 in the 'Annals of Natural History' for January 1858 (Suppl. to 

 vol. XX.), I described this Elater as new, under the name of " Mo- 

 nocrepidius? Grayii;" but the identical individual from which I 

 drew out my diagnosis has since been identified by M. Candeze 

 with the Cryptohypnus grisescens of Germar. It seems to have 

 a rather wide geographical range, occurring in Mesopotamia, 

 Syria, Senegal, &c. ; and I possess specimens captured by the 

 late Mr. Melly in Egypt.
