CURCULIONID^E. 293 



zarote and Grand Canary, in both of which however there can be no 

 question that it must exist. Its detection in Gomera is due to the 

 late researches of the Messrs. Crotch. 



810. Apion calcaratum. 

 Apion calcaratum, WolL, Cat. Can. Col. 310 (1864). 



Habitat Canarienses (Hierro), plantas Carduorum nisi fallor destruens. 



The only four examples which I have seen of this Canarian Apion 

 were collected by myself I believe, off Thistles, in the sylvan dis- 

 trict of El Golfo on the western side of Hierro. It may be re- 

 garded as the representative at the Canaries of the common European 

 A. carduorum, to which indeed it is closely allied. 



811. Apion Westwoodii. 

 Apioii Westwoodii, WolL, Cat. Can. Col. 311 (1864). 



Habitat Canarienses (Can.), in intermediis et editioribus rarissimum. 



Peculiar, so far as I have yet observed, to Grand Canary where 

 it is exceedingly rare, at intermediate and lofty elevations. I have 

 taken it in the district of El Monte, and likewise, at a very high 

 altitude, in the great Final of the central region of Tarajana. 



812. Apion tnbiferum. 



Apion tubiferum (Dej.), Schon., Gen. et Spec. Cure. i. 284 (1833). 

 , WolL, Cat. Can. Col. 311 (1864). 



Habitat Canarienses (Can., Hierro'), foliis Cistorum ut mihi videtur 

 in editioribus delectatum. 



The A. tubiferum of Mediterranean latitudes appears to occur, 

 though very sparingly, at the Canaries. Indeed the only four 

 examples of it which I have yet seen were captured by myself (I 

 believe, off plants of Cistus) in Grand Canary and Hierro namely, 

 in the sylvan district of El Golfo, of the former, and at a very 

 high elevation above the Final of Tarajana, in the latter. 



813. Apion austrinnm. 

 Apion austrinum, WolL, Cat. Can. Col. 312 (1864). 



Habitat Canarienses (Gom.), a W. D. Crotch semel repertum. 



A single example of this small Apion (which has much the general 

 appearance of the European A. seniculus) was captured by Dr. Crotch
