206 Mr. T. V. WoUaston on Coleoptera from St. Vincent. 



municated to me, by M. Deyrolle of Paris, as the " Caragonia 

 (Solier) canariensis (Keiche) ;" but the genus " Caragonia," if 

 indeed it were estabhshed by Sober, has certainly never been 

 pubhshed ; whilst the specific name, even if it were not a manu- 

 script one (as I beUeve it to be), would of necessity have to be 

 changed, since it conveys a false notion of the habitat, the insect 

 being strictly a Cape de Verde one, and having nothing what- 

 ever to do with the Canaries. With respect to these two titles. 

 Prof. Lacordaire writes to me as follows : — 



" Je possede aussi depuis longtemps cette espece, sous le nom 

 de Phylax validus, Dej., et comme provenant des lies du Cap 

 Vert. Quant au nom generique de Caragonia, Solier, je n'en ai 

 jamais entendu parler, et je suis certain qu^il n'a ete publie 

 nulle part. Get insecte est nouveau; MM. Mulsant et lley ne 

 Font pas decrit, a ma connaissance, dans leur travail sur les 

 Pedinides. II reutre dans les Opatrides du groupe des Phylacides, 

 oxx. il doit former un genre particulier parmi ceux qui ont les 

 yeux incompletement divises. Je le placerais par consequent 

 immediatement avant les Hadrus." 



Not to mention many smaller distinctions, I may observe that 

 Trichosternum, differs from Hadrus in its larger and less trans- 

 verse scutellum, its less glabrous surface (its sides above being 

 sparingly setose, and its prosternal lobe very densely so), in its 

 simple mentum, thicker mandibles and limbs, its more evidently 

 dilated anterior tibiae, and in its most anomalous and laterally- 

 serrated upper lip. This last, indeed, is very curious, and ap- 

 pears to be composed of two closely-applied lamince, of which the 

 upper one is very rqbust, deeply bilobed and sparingly ciliated 

 in front ; whilst the under one is thickly ciliated at its anterior 

 angles, but free from setse at its apex, and much les^ scooped- 

 out than the other — an arrangement which causes the emargi- 

 nation of the upper plate to be partially filled-in by the more 

 prominent lower one. 



26. Trichosternum striatum, n. sp. 

 T. nigrum, subopacum ; capite leviter rugoso-punctato ; prothorace 

 parcius asperate puuctato, ad latera sequaliter rotundato ; scutello 

 ruguloso ; elytris subtilissime et parce asperatis, longitudinaliter 

 striatis, interstitiis couvexis, ad utruraque latus parce setosis ; 

 antenuis versus apicem tarsisque paulo picesceutioribus. 

 Long. Corp. lin. 5-6. 



The present insect appears to be very common at St. Vincent, 

 and in all probabdity on the other islands likewise. It was 

 taken abundantly by IMr. Gray and the Rev. Hamlet Clark in 

 Decemberl856 ; by my nephew, Mr. F.W.Hutton, in June 1857; 

 and on a subsequent occasion, during the month of October, by 

 Mr. Fry. [To be continued.]
