insect) it unquestionably possesses a few distinctions of its own, 

 which are very evident when examined with care. Thus, for in- 

 stance, the rostrum of its female is a little slenderer and more convex 

 than that of the globulipennis ; its prothorax is relatively narrower 

 and more conical, and when denuded of its scales will be seen to be 

 less constricted behind the apex, as also more deeply and less closely 

 punctured; and its elytra are even convexer still especially at 

 their base. 



The A. pilula is widely spread over the sylvan and subsylvan 

 districts of the Canarian Group, at any rate in the central and 

 western portions of it. I have taken it in Teneriffe and Palma, and 

 it was found sparingly by the Messrs. Crotch in Gomera and Hierro.

Habitat Canarienses (Ten., Gom., Palma), in lauretis humidis editi- 

 oribus sub cortice laxo truncisque putridis rarior. 



A large and most distinct Canarian Acalles, which seems to be 

 peculiar to the damp sylvan regions of a lofty altitude. I have 

 taken it beneath the loosened bark of trees, as well as under moist 

 rotting wood, in Teneriffe and Palma ; and several specimens are 

 now before me which were captured by the Messrs. Crotch, in the 

 laurel-district above Hermigua, in Gomera.

Habitat Canarienses (Gom., Palma, Hierro}, in sylvaticis intermediis 

 degens. 



Apparently peculiar to the western portion of the Canarian Group, 

 where it occurs at intermediate altitudes, principally within the 

 sylvan districts. I have taken it in Palma and Hierro ; and it was 

 captured by the Messrs. Crotch in the latter, as well as (above Her- 

 migua) in Gomera. Although variable in tint, it is usually an ob- 

 scurely coloured insect ; but it may always be known by the rather 

 long and erect setai with which it is studded, and by the punctures
