CANARIAN COLEOPTEBA. 135 



the present species and the following one, I must refer to my Paper 

 on the " Eu2)7torbia-'m{esting Coleoptera of the Canaries " which has 

 been lately published in the ' Transactions of the Entomological 

 Society of London.' The T. subelUpticus seems to be decidedly rare, 

 though possibly it might occur in considerable abundance were the 

 rotten stalks of the Euphorbia canariensis to be well searched. The 

 only specimens which I have seen were captured by myself, in the 

 putrid stems of the above-mentioned plant, on the mountains above 

 S*'* Cruz of Teneriffe, in the direction of Las Mercedes.

Habitat Gomeram, e plantis Euphorbice canariensis putridis in mon- 

 tibus supra San Sebastian mense Februario a.d. 1858 lectus. 



The present Thallestus has precisely the same habits as the last 

 one ; but was found in Gomera instead of Teneriffe, and in consider- 

 able abundance. I captured it, early in February 1858, from out of 

 the putrid stems of Euphorbia canariensis on a hill-top to the north 

 of San Sebastian.

Habitat Lanzarotam, Fuerteventuram, Teneriffam et Palmam, 

 passim. 



The European C. dentatus appears to have established itself com- 

 pletely at the Canaries, in like manner as it has at Madeira, — being 

 found not only about houses and granaries, but also in positions far 

 removed from the towns. I have taken it under the refuse at the 

 base of corn-stacks in Lanzarote, from beneath camels' dung in the 

 Rio Palmas of Fuerteventura, from under the bark of trees at the 

 Agua Garcia and the Agua Mansa of Teneriffe, and in similar posi- 

 tions in Palma. It is a variable insect, both in size and colour — 

 assuming sometimes, particularly in sylvan spots, a dark-brownish 

 hue ; but its rather elongate outline and the shape of its prothorax 

 will always serve to identify it.
