CANARIAN COLEOPTERA. 121 



confined to the Pinus canariensis of the old Finals, in the same man- 

 ner as that insect is attached to the various laurels. It would seem 

 to be even scarcer than its ally ; though from the difficulty of reach- 

 ing many of the elevated regions and precipitous mountain -slopes in 

 which the fir-trees occur, it may perhaps in reality be rather local 

 than absolutely rare. I have taken it sparingly in Tencriff'e (from 

 under the loose bark of a felled pine-tree at the Agua Mansa), and 

 in the region of the Banda of Palma.

The only specimen which I have seen hitherto of this insect was 

 captured by myself, within the putrid stems of a Euphorbia cana- 

 riensis, on the mountains above ^^ Cruz of Teneriffe, — in the di- 

 rection of Las Mercedes.

The almost cosmopolitan T. mauritanica is doubtless an introduced 

 insect in these islands, — no less than it is at Madeira. It has, how- 

 ever, completely established itself in various places, where it is often 

 excessively common. It is beneath the refuse which strews the 

 ground around the base of corn-stacks where it more particularly 

 abounds; and in such situations I have observed it plentifully in 

 Lanzarote and Fuerteventura,- — in company with the Silvanus suri- 

 namensis, Aglenus brunneus, Tenebrio ohscurus, Cryptophagus dentatus, 

 Corticaria serrata, and certain other species. And I have taken it 

 in houses (in the neighbourhood of grain, and other farinaceous sub-
