286 CANAEIAN COLEOPTHEA. 



justified in admitting the insect into the present Catalogue. But 

 since, in point of fact, I myself captured a single individual (crawl- 

 ing on the outside of a house at the Puerto Orotava) in Tenerifie, 

 of a species which is so near to M. Chevrolat's that I imagine it 

 cannot be regarded as more than a variety of it, I further conceive 

 that it may safely be recorded (not merely as Canarian but) as Tene- 

 riffan ; and I have consequently entered it as such. 



The note above alluded to was to the effect that the insect under- 

 went its transformations within the stems of the JEoniuni frutescens 

 {ionium being, as I am informed by the Kev. R. T. Lowe, " a 

 needless genus of Webb's made out of Sempervlvmn, Linn., and cm- 

 bracing about twelve out of the numerous Canarian Sempervlva "). 

 And as this accords well with my own observations on the mode of 

 life of the A. argillosus, to which it is most nearly allied, I accept it 

 unresei'vedly, and have adopted the name proposed for it by M. 

 Chevrolat.

Habitat Gomeram, supra " Hermigua " a Dom. Crotch lectus. 



The six specimens from which the present diagnosis has been com- 

 piled were taken by Dr. Crotch at Hermigua, in Gomera, during the 

 spring of 1862. They have no very decided distinguishing specific 

 character, and appear in some measure to be intermediate between 

 the A. ceonii and acutus, being smaller and more variegated than 

 the former, more suddenly (and shortly) constricted behind, with 

 their male rostrimi rather more abbreviated, and their female one 

 slenderer, more cylindric, more rufescent, and more lightly punc- 

 tured, — but larger than the latter, less acute posteriorly, and alto- 

 gether a little less setose, with their rostrimi in both sexes some- 

 what more coarsely punctured — the male one moreover being broader, 

 and the female one longer, than is the case in the A. acutus. 



To what extent the characters of aU these Canarian Acalles are 

 liable to vary, it is most difficult to ascertain ; and further material 

 must decide whether any of those here enumerated are due to either 

 local influences or isolation.
