the Canarian islands except Lanzarote and Grand Canary (in both 

 of which, however, we may be pretty sure that it exists).

Habitat Maderenses (Mad.}, et Canarienses (Ten., Gom., Hierro}, in 

 herbidis subinferioribus intermediisque, passim. 



A European species which is widely (though sparingly) diffused 

 over these Atlantic islands, where in all probability it will be found 

 to be well nigh universal. It occurs amongst herbage, at rather 

 low and intermediate elevations, chiefly within the cultivated dis- 

 tricts ; and it has been captured in Madeira proper, as well as in 

 Teneriffe, Gomera, and Hierro of the Canarian Group. Its detection 

 in Gomera is due to the late researches of the Messrs. Crotch. I am 

 informed by Mr. G. E. Crotch that it is identical with the C. mixtus 

 of Mulsant and Key ; and indeed a recent inspection of an example 

 of the latter, which was taken by myself in the east of England, 

 leaves no doubt on this point. 



746. Ceuthorhynchus phytobioides. 



Ceuthorhynchus phytobioides, Woll, Cat. Can. Col 281 (1864). 

 Habitat Canarienses (Ten.), ad folia Sedi in sylvaticis rarissimus. 



A single example only of this Canarian Ceuthorhynchus has hitherto 

 come beneath my notice. I met with it in the sylvan region above 

 Taganana, in the north of Teneriffe. 



747. Ceuthorhynchus hesperus. 



Ceuthorhynchus hesperus, Woll., Cat. Can. Col. 282 (1864). 



Habitat Canarienses (Gom.., Hierro), ad rupes herbidas in editioribus 

 folia Sedi destruens. 



Likewise Canarian and exceedingly scarce. I have taken it at a 

 high elevation in Hierro (where it was also captured by M. de la 

 Perraudiere), and it was found by the Messrs. Crotch in Gomera. 



As conjectured in my late Catalogue, the habits of the C. phyto- 

 bioides, hesperus, and lineatotessellatus are identical the three 

 insects being attached to the succulent leaves of the various species 

 of Sedum and Sempervivum, which form so marked a feature on the 

 sides of the perpendicular rocks at intermediate and lofty altitudes.
