CUllCULIONID^E.

 Sitones cambricus, Id., Cat. Can. Col. 376 (1864). 



Habitat Maderenses (Mad., P to S to ) et Canarienses (Can., Ten.}, sub 

 lapidibus, passim. 



A European Sitona which is rather common in the east of Madeira 

 proper, as well as in Porto Santo, of the Madeiran Group ; and we 

 may be pretty sure that it must occur on the Desertas likewise. In 

 the Canaries it is decidedly scarce, the few specimens which I have 

 yet seen having been taken by myself in Grand Canary and Teneriife.

Habitat Maderenses (Mad., P to S to ) et Canarienses (Can., Ten.,Palma\ 

 pra3cipue in cultis ; forsan ex Europa introductus. 



This common European insect will most likely be found to be 

 universal (or nearly so) throughout these Atlantic islands, where 

 very probably it has become established from more northern latitudes. 

 It occurs for the most part about corn-fields, and in other cultivated 

 grounds. It is rather abundant in Madeira proper and Porto Santo, 

 of the Madeiran Group ; and I have taken it in Grand Canary, Tene- 

 riffe, and Palma, of the Canaries.

Habitat Maderenses (Mad., P to S to ) et Canarienses (ins. otnnes), ple- 

 rumque in aridis calcariis inferioribus late sed parce diffusus. 



Likewise a common European species, and one which is perhaps 

 more widely spread over these Atlantic Groups than any of the Sitonce 

 hitherto detected. Yet it is nowhere abundant though with the 

 appearance of being more truly indigenous than any of the remainder, 

 except perhaps the punctiger and seriesetosus. It occurs for the most 

 part at rather low elevations, and in dry or calcareous spots. I have 

 taken it in Madeira proper and Porto Santo, as well as in the whole 

 seven islands of the Canarian archipelago.
