10 CARABID.E. 



Canarian, and confined to very lofty elevations. I have taken it on 

 the Cumbre adjoining the Caiiadas, in Teneriffe ; and it was found 

 (during the summer of 1864) by the Messrs. Crotch at a high alti- 

 tude on the mountains above Hermigua, in Gomera, "above the 

 cataract ; between it and Monte Euerte." 



The Gomeran specimens seem on the average to be a trifle larger 

 than the Teneriffan ones, with their prothorax and limbs a little 

 more elongated, and with the apices of their elytra more rounded off 

 (separately). Their punctation also is not quite the same, it being, 

 if anything, at all events on the forehead, a little more remote, and 

 on the prothorax and interstices not quite so deep. But such slight 

 differences cannot, I think, indicate more, at the utmost, than an 

 unimportant insular phasis of the species. Nevertheless having 

 pointed out the distinctions (such as they are), I would at any rate 

 cite the Gomeran form as " var. /3. aptinoides"

The T, suturalis was supposed formerly to be peculiarly an 

 Egyptian insect, whereas in reality it is well nigh universal through- 

 out these Atlantic islands having been taken in the whole three 

 groups. At the Madeiras it is more especially abundant in the low 

 arid districts of Porto Santo ; nevertheless it is found likewise on 

 the Ponta de Sao Lourengo (the extreme eastern promontory) of 

 Madeira proper, and on the Deserta Grande. Erom the Salvages a 

 single example was obtained by the Barao do Castello de Paiva, from 

 the larger (or northern) island ; whilst at the Canaries it teems in 

 certain dry and sandy places of Lanzarote, Euerteventura, and Grand 

 Canary. So that, both at the Madeiras and Canaries, it would seem 

 to be common in the eastern parts of the respective archipelagos, 

 and to disappear gradually as we approach the west.
