sylvan districts ; and if (as lately implied) the A. ornatus be regarded 

 as the representative in that island of the Canarian A. fortunatus, 

 the present species is as assuredly the Madeiran analogue of the se- 

 nilis of the Canarian Group. Yet, on the whole, I think that it is 

 perhaps more distinct from the latter than the ornatus is from the 

 fortunatus ; so that, d fortiori, I cannot treat it as any local modifica- 

 tion of that insect.

Acalles brevitarsis, Wott., Cat. Can. Col 289 (1864). 

 Habitat Canarienses (Can.'), in intermediis lectus. 



The only district in which I have taken this Acalles is that of El 

 Monte in Grand Canary. It has a good deal in common with the 

 acutus, of Teneriffe ; but the characters which distinguish it from that 

 insect have been fully alluded to in my Canarian Catalogue. 



766. Acalles acutus. 



Acalles acutus, Wott., Cat. Can. Col. 289 (1864). 

 Habitat Canarienses (Ten.}, in sylvaticis intermediis parum vulgaris. 



A Canarian Acalles which is widely spread over the sylvan districts 

 of Teneriffe, where it is tolerably common. Whether it occurs else- 

 where in the archipelago I am doubtful ; for although a few rubbed 

 and unsatisfactory individuals which I have examined from Grand 

 Canary and Gomera have much the appearance presented by equally 

 bad ones of this species, I cannot regard them as affording evidence 

 one way or the other since (as stated in the remarks at the com- 

 mencement of this genus) examples of these variable, scale- covered 

 Curculionidce in that kind of condition are generally quite useless, 

 as being simply undeterminable. As hitherto observed, therefore, I 

 do not think that it would be safe to record the A. acutus positively 

 for any island except Teneriffe.

Acalles instabilis, Wott., Cat. Can. Col 290 (1864). 



Habitat Canarienses (Can.?, Ten., Gom.t, Palma*!), in sylvaticis,

Like the last species, widely spread over the laurel-districts of 

 Teneriffe; but whether the more or less imperfect and abraded 

 examples from Grand Canary and Gomera which I have (provision-
