 in intermediis degens. 



The C. echii, which is so generally spread throughout Europe, 

 will probably be found to be universal in the Madeiran Group; 

 though it has not yet been observed in the Canaries. It occurs on 

 the foliage of the Echium violaceum, L., at rather low and interme- 

 diate altitudes ; and it has been captured in Madeira proper, Porto 

 Santo, and the Deserta Grande.

Habitat Canarienses (Ten., Gom., Hierro), in foliis Urticarum hinc 

 inde minus frequens. 



A common European Ceuthorhynchus which occurs very sparingly, 

 at low and intermediate elevations, in the Canarian Group for the 

 most part on the foliage of nettles, in semicultivated spots. I have 

 taken it in Teneriffe and Hierro, and it was found by the Messrs. 

 Crotch in Gomera.

Habitat Maderenses (Mad., Des.) et Canarienses (Fuert., Ten., Gom.,

Almost universal (perhaps indeed quite so) throughout these At- 

 lantic islands, where very likely it may have become established 

 from more northern latitudes. It occurs sparingly in semicultivated 

 spots of intermediate elevations, and has been captured in Madeira 

 proper and the Deserta Grande of the Madeiran Group, and in all
