328 CANAEIAN COLEOPTERA. 



with dark and whitish scales (the latter of which preponderate 

 towards the sides and apex, as also on the hinder disc of each), should 

 be particularly noticed. 



So far as I have observed hitherto, the H. irrorata is confined to 

 Lanzarote and Fuerteventura, and is extremely local even in those 

 islands, occurring principally in sandy and calcareous spots of a low 

 elevation. In the former I took it, from beneath stones, during 

 March and April of 1859, in the flat, arid district immediately to the 

 south of Arrecife ; as also on the calcareous slopes adjoining the town 

 of Betancuria in the latter.

Habitat insidas omnes Canarienses, vulgaris ; forsan introducta. 



This common European weevil is universal at the Canaries, in the 

 whole seven islands of which I have myself captured it (more or less 

 abundantly). In Lanzarote, Fuerteventura, and Teneriffe it was 

 taken by Mr. Gray also ; and in the last of those islands by Dr. 

 Crotch and the Barao do Castello de Paiva. It occurs principally 

 about cidtivated grounds and corn-fields, and in all probability is a 

 mere importation from more northern latitudes. It is equally abun- 

 dant in the Madeiran Group, being found in Madeira proper, Porto 

 Santo, and on the Desertas. It is a variable insect ; and I beKeve 

 that the Canarian examples certainly include amongst them the form 

 which I have recorded (perhaps erroneously) in my ' Ins. Mad.' as 

 the H. murina, but which I now suspect cannot be specifically dis- 

 tinct from the remainder ; though whether it be really coincident 

 with the true murina of Fabricius I wiU not undertake to pronounce 

 for certain.
