species of the genus), I have not the slightest doubt that that insect 

 is identical with the AcalJcs argUlosus, and he expressly states 

 (though, as usual, without any reference to the island in which it 

 was found) that MM. Webb and Berthelot record its capture " dans 

 les branches et les vieux trones du Cacalia Kleinia " — which is the 

 savie plant as DeCandoUe's K. nenifolia. 



M. Chevrolat has kindly communicated to me, from his collection, 

 a type of Schcinherr's A. argillosus, which appears to differ in no 

 respect from my Teneriffan specimens except that its scales are a 

 little paler stiU, or more silvery. I have, therefore, no doubt as to 

 the synonymy of the species.

As already implied, the distinctly darker, or browner, scales with 

 which this species is clothed, and its slightly longer and more ar- 

 cuated rostrum (at any rate of the females), which in both sexes is 

 more roughly punctured and is also more naked posteriorly, which 

 causes it to appear more conspicuously incised on either side of its 

 extreme base, in conjunction with its prothorax being somewhat 

 narrower behind, the termination of its elytra rather more pointed 

 and entire (or less obtusely bisinuated), and its feet just perceptibly 

 longer and less squamose, will serve to separate it from its near ally 

 the A. argillosus. 



The specimens (eight in number) from which the above diagnosis 

 has been compiled have been communicated by M. Chevrolat, who 

 purchased them from the material of a French naturalist who 

 collected plants (and a few insects) at the Canaries and elsewhere. 

 And I think that the note which accompanied them, as to their 

 habits, is sufficiently special to vouch for its accuracy ; so that even 

 if no other evidence had existed I believe that I should have been
