Habitat Maderenses (Mad.) et Canarienses (Ten.), hinc inde sub 

 lapidibus in intermediis. 



This common European insect is widely spread over the interme- 

 diate elevations of Madeira proper, where it appears to be truly indi- 

 genous ; but at the Canaries it is extremely rare, the few specimens 

 which I have seen having been taken (by myself above the Agua 

 Garcia, and by the Messrs. Crotch and myself at Ycod el Alto) in 

 Teneriffe.

Habitat Maderenses (Mad.), a Dom. Bewicke in cultis intermediis 

 semel capta. 



The only example of this European Curculionid which I have yet 

 seen from these Atlantic islands was captured by the late Mr. 

 Bewicke in Madeira proper at " the Mount," above Eunchal. It 

 is not unlikely that the species may have been introduced acci- 

 dentally from more northern latitudes perhaps through the agency 

 of the English residents, who have long been in the habit of im- 

 porting boxes of plants (at intervals) to replenish their gardens. 

 Still this is but a conjecture ; and it is probable, even if it be the 

 case, that the insect has at all events become established.

* Fortunately it is not often that a species which has been established in the 

 Appendix of a volume has to be suppressed in the text ; yet I am compelled in 

 the present instance to do so, from having been led into an unaccountable mis- 

 take concerning a Canarian Curculionid which was communicated a few months 

 ago by De Marseul. The individual in question being immature, and also re- 

 markably small, I failed to recognize it as the Atlantis tibialis, to which I am 

 now satisfied that it should be referred ; and so I inadvertently described it as a 

 large, aberrant Lichenophagus, under the trivial name of incomptus. As implied 

 however in the Appendix, I did not feel at all satisfied about its affinities, and 

 even proposed for it (in consequence) a subgeneric title. Yet the recent trans-
