CANARIAN COLEOPTERA. 213 



antennae, palpi, and legs being always more or less infuscated — the 

 two former being occasionally much darkened. I have taken it, rather 

 abundantly, from beneath stones, during the spring, both on the lofty 

 Cumbre (adjoining the Caiiadas) above Ycod el Alto, and likewise on 

 the opposite one (separated from the other by the great interval which 

 constitutes the valley of Orotava) above the Agua Mansa ; and I have 

 also captured it, though more sparingly, at the Agua Mansa itself. 

 This last locality represents the lowest altitude (about 3500 feet) at 

 which I have hitherto observed it. Dr. Crotch likewise met with it 

 on the Cumbre above Ycod.

Although unwilling to establish an additional species amongst 

 these variable Coptostetlii from the evidence afforded by a single ex- 

 ample, I am nevertheless compelled to do so, since the insect from 

 which the above diagnosis has been compiled differs so essentially 

 from all the others here enumerated that I cannot possibly refer it 

 to any of them. In its general colour, however, and deeply striated 

 elytra (with their convex interstices) it has perhaps a greater affinity 

 with the 0. globidicolUs than with any of the remainder ; but its 

 comparatively enormous bullc and longer, more erect, and denser pu- 

 bescence, combined with its more elongate limbs and totally different 

 prothorax, which is scarcely narrower behind than in front, will 

 readily separate it from that sjjecies. The unique specimen was 

 captured, during May 1859, in the sylvan region of the Agua Mansa, 

 in Teneriffe. 



334. Coptostethus crassiusculus, n. sp. 



C nitidiusculus, subobtusus, niger elytris vix dilutioribus, subful- 

 vescenti-pubescens ; prothorace convexo, basi vix angustato ; ely- 

 tris basi minus contractis, pube longiuscula suberecta tenui dense 

 vestitis, leviter crenato-striatis, interstitiis depresses ; antennis 

 pedibusque pallide testaceis. 



Variat elytris vel concoloribus vel ad humeros laete rufescentioribus, 

 necnon (immaturus) colore omnino ferrugineo.
