Genus TENEBRIO. 

 Linnaeus, Syst. Nat. edit. 6 (1748). 



Tenebrio Crotchii, n. sp. 



T. aterrimus, nitidus ; capite prothoraceque transversis ac profunde 

 punctatis, illo insequali et mox pone oculos (genis baud profunde 

 incisos) subito in collum angustato, hoc postice vix angustato (ad 

 latera oblique subrecto) angulis anticis valde rotundatis, posticis 

 argute obtusis, per marginem basalera recte truncate, in limbo 

 tenuiter marginato, basi utrinque fovea brevissima impresso ; scu- 

 tello triangulariter subpentagono ; elytris basi recte truncatis, pro- 

 funde punctato-striatis, in interstitiis minutissime parce punctu- 

 latis ; antennis pedibusque saipius subpicescentioribus, tibiis mas- 

 culis arcuatis. Long. corp. lin. 4-4^. 



Habitat Teneriffam et (praecipue) Gomeram, a DD. Crotch in Euphor- 

 bia canariensi emortua copiose deprehensus. Tenebrio late 

 distinctus insulisque Canariensibus valde indigenus, necnon in 

 honorem amici G. E-. Crotch, entomologi inter Anglicanos periti, 

 oculatissimi, perillustris, indefessi, citatus. 



The discovery of this small, but most distinct and remarkable 

 Tenebrio is due to the late Canarian researches of the Messrs. Crotch 

 who captured it abundantly in Gomera, and more sparingly near 

 Buenavista in the north-west of Teneriffe. Judging from their 

 report, it appears to be peculiar to the dead stalks of the Euphorbia 

 canariensis "in the tops and bottoms" of which, according to a 

 note now before me, it " swarms, when the Lepidoptera have left." 

 Such being the case it is certainly remarkable that it should have 

 totally escaped my own observations in those islands ; though as I 

 searched but little in Gomera, and less in the E. canariensis than in 

 any of the Euphorbias, this is perhaps partly accounted for. I have 

 had much pleasure in dedicating the species to my friend Mr. G. R. 

 Crotch, to whose entomological labours (in conjunction with those 

 of his brother) we are indebted for so large a number of interesting 

 and important additions to the Canarian Coleoptera. 



Apart from a number of minor distinctions which have been re-
