CANARIAN COLEOPTERA. 319 



of their elytra less divergent (indeed almost straight) and their pro- 

 thorax rather more densely variolose. Still, in every other respect, 

 particularly coloration, they agree with the anguimis ; and I do not 

 think therefore that it would be safe to treat them as more than 

 small varieties of that insect. And moreover, as M. Brulle registers 

 the species as Canarian, it is at least possible that Messrs. Webb and 

 Bcrthelot's examples were more normal in their characters ; or, at 

 any rate, the fact of its having been thus recorded gives an additional 

 prohahility to the correctness of my determination, and likewise (apart 

 from this) an additional reason for the desirabDity of admitting the 

 species, even independently of my own specimens, into this Catalogue. 

 My own belief, however, is that the latter are truly referable to the 

 anguimis, and that the slight peculiarities which they present indi- 

 cate no more, at the utmost, than a mere geographical variety. One 

 of these examples I captured in the south of Grand Canary, and the 

 other near S'" Cruz in Teneriffe.

Of this Lixus also I have seen as yet but two Canarian examples, 

 both of which have lately been communicated from Fuertevcntura 

 by the Barao do Castello de Paiva. Although not in a very satisfac- 

 tory state of preservation, I can detect no traces whatever of paler 

 lines down the disc of their elytra (though there is a broad and con- 

 spicuous one along either side), whilst their other differences from 

 the anguhms, such as they are, accord so weU with the diagnosis of 

 the (Grecian and Egyptian) anguiculus that I have little hesita- 

 tion in referring them to that species. Apart from their want of 

 elytral lines, their rostrum is just perceptibly more shining and eon- 

 vex than is the case in the anguinus, their j)rothoracic keel is a trifle 

 more evident, and the acuminated apices of their elytra are straighter, 

 or less divergent. They are also perhaps a little narrower, though 

 I think scarcely shorter ; in which latter respect, consequently, they 

 do not accord precisely with the published diagnosis of the anguiculus.
