CANARTAN OOLEOPTERA. 211 



riffe ; and I subsequently captured it at the Agua Garcia, on the 

 mountains above S''^ Cruz, and at Las Mercedes and Taganana, in the 

 same island ; as also in the Barranco de Galga of Palma, and near 

 Valverde in Hierro. But it is decidedly everywhere scarce. The 

 var. was found in the district of El Golfo, on the western side of 

 Hierro. 



330. Coptostethus gracilis, n. sp. 



O. angusto-elongatus. fusco-niger elytris plus minus brimneis, fulvo- 

 pubescens ; jjrothorace elongato, basi angustato ; elytris pube sub- 

 crecta tenuissima vestitis, sat profunde erenato-striatis, interstitiis 

 subconvexis ; antenuis pedibusque elongatis pallide testaceis, tarsis 

 pra3sertim elongatis gracilibus. 



Var. /3. Elytris ad humeros paulo rufescentioribus. — Long. corp. lin. 



Habitat in montibus excclsis Teneriifce, usque ad 8000 vel 9000' 

 8. m. ascendens. 



Whether this be anything more than a small and narrow state of 

 the C. hrunneipennis, peculiar to the higher regions of Teneriffe, I 

 will not undertake to pronounce. Judging, however, from the six 

 individuals now before me, it is not only smaller and narrower than 

 that insect, but is perhaps of a somewhat browner hue, its prothorax 

 is a little more drawn-in at the base, and its legs (particularly the 

 tarsi) are relatively rather longer still ; it is likewise a trifle more 

 opake ; and in aU the specimens except one (which was found at a 

 lower altitude) the shoulders are concolorous with the rest of the sur- 

 face. Three of my examples were captured, from beneath stones, 

 in the lofty district adjoining the Caiiadas, above Ycod el Alto (at 

 an elevation of more than 8000 feet), during May 1859 ; and two a 

 few weeks later, in similar situations, on the opposite Cumbre, above 

 the Agua Mansa ; whilst the remaining one {var. ft) was taken at 

 the Agua Mansa itself. 



331. Coptostethus canariensis. 



C. nitidiusculus, niger elytris vel vix vel distincte fuscescentioribus, 

 subcinereo-pubescens ; prothorace convexo, basi angustato, antice 

 lato, prosterno antice subhorizontali ; elytris convexis, pube brevi 

 subdemissa tenui parce vestitis, ad humeros oblique truncatis, 

 leviter erenato-striatis, interstitiis subdepressis ; antennis pedi- 

 busque gracilibus, pallido-tcstaceis. 



Variat elytris ad humeros plus minus obscure dilutioribus necnon 

 (immaturus) colore omnino ferrugineo. — Long. corp. lin. 2- vix 2|.
