elevations. Hitherto it has been taken only in Teneriffe and Palma, 

 but it will probably be met with wherever the Finals still exist. 



1160. Hypophlceus euphorbias. 



Hypophloeus euphorbias, Woll, Trans. Ent. Soe. Lond. i. 183 

 , Id., Oat. Can. Col 499 (1864). 



Habitat Canarienses (Lanz., Can., Ten., Gom., ffwrro), sub cortice 

 Euphorbiarwn emortuo late sed paree diffusus. 



A very narrow and comparatively minute species which occurs 

 sparingly under the bark of dead Euphorbias in the Canarian Group, 

 in all the islands of which it has been detected except Euerteventura 

 and Palma. There can be little doubt, consequently, that it is uni- 

 versal. It has much the same habits as the Madeiran H. ambiyuus, 

 of which it may be regarded as the Canarian representative. It 

 differs however from that insect in being altogether narrower, with 

 its prothorax relatively longer (and not transverse), with the stria? 

 of its elytra (the latter of which completely cover the apex of the 

 abdomen) both fainter and more finely punctulate, and with its 

 antennae less abbreviated. 



1161. Hypophlceus ambiguus. 



Hypophloeus ambiguus, WolL> Cat. Mad. Col. 152 (1857). 



Habitat Maderenses (Mad.), in Euphorbiis antiqnis, nisi fallor, parce 

 degens. 



The few examples which I have yet seen of this Hypophlceus were 

 taken in the higher elevations of Madeira proper ; and although I 

 have not myself met with it, I feel almost satisfied (from its mani- 

 fest affinity with the preceding species) that it is attached to the 

 Euphorbias. Indeed I have little doubt that the individuals from 

 which my diagnosis was originally compiled, and which were taken 

 by Mr. Mason in the upland region of the Eanal, must have occurred 

 beneath the bark of the E. mellifera which attains a gigantic size 

 in that particular district. 



1162. Hypophlceus subdepressus. 



Hypophloeus subdepressus, Wott., Cat. Can. Col. 499 (1864). 

 Habitat Canarienses (Fuert.), hactenus semel deprehensus. 



Closely allied to the European IL depressus, of which, indeed, it is 

 just possible that it may represent some geographical state; but
