TENEBRIONIDjE. 425 



been observed in all the seven islands except Lanzarote (where, 

 however, we may be quite certain that it exists). It occurs about 

 granaries and bakehouses, but is more particularly abundant beneath 

 the refuse around the base of corn-stacks. 



1167. Tenebrio olivensis. 



Tenebrio olivensis, WolL, Cat. Can. Col. 501 (1864). 

 Habitat Canarienses (Fuert.), sub lapide in intermediis semel lectus. 



Of this curious Tenebrio a single specimen is all that I have yet 

 seen. It was captured by myself in Fuerteventura, of the Canarian 

 Group from beneath a stone on a flat semicultivated piece of 

 ground, about a mile to the south of Oliva. In the very acute 

 angles of its prothorax, and the wide and extremely securiform last 

 joint of its maxillary palpi, it would appear at first sight to recede 

 almost generically from the other species here enumerated. 



1168. Tenebrio Crotchii, 



Tenebrio Crotchii, Woll., Append, huj. op. 62. 



Habitat Canarienses (Ten., Grora.), in caulibus Euphorbice canariensis 

 emortuis a DD. Crotch copiose deprehensus. 



A remarkable little Canarian Tenebrio, of Euphorbia-infesting 

 habits, which was captured abundantly by the Messrs. Crotch in 

 Teneriffe and Gomera. It is a truly indigenous insect ; and it will 

 perhaps therefore be found to be widely spread over the archipelago, 

 when the dead stalks of the Euphorbia canariensis (to which plant 

 it would seem to be attached) have been more generally examined.
