STAPHYLINIDJE. 471 



A few examples of this Canarian Homalota, which appears to be 

 perfectly distinct from the preceding two species, were taken by 

 myself in Lanzarote and Palma. It seems to occur under decaying 

 vegetable refuse, and will probably be found to be pretty generally 

 distributed over the Group.

 Homalota Waterhousii, WolL, Cat. Can. Col. 548 (1864). 



Habitat Canarienses (Ten., Hierro), rarior. In editioribus praecipue 

 occurrit, usque ad 8000' s. m. ascendens. 



Kather a large species which seems to occur sparingly in the 

 higher elevations of the Canarian Group, ascending to an altitude 

 of about 8000 feet. I have captured it in Teneriffe (at Ycod el Alto, 

 as well as at the Agua Mansa and on the lofty Cumbre above it) ; and 

 it was found by the Messrs. Crotch both in that island and Hierro. 



1300. Homalota longicornis.

Habitat Maderenses (Mad.), in stercore et sub quisquiliis vulgaris. 



The European H. longicornis is common in Madeira proper, where 

 it occurs at most elevations and principally in the dung of cattle ; 

 but as it has not yet been detected in any of the other islands, it is 

 far from unlikely that it may have become established accidentally 

 from more northern latitudes.

Habitat Maderenses (Mad., P to S to ) et Canarienses (ins. omnes), in 

 stercore et sub quisquiliis, ab ora maritima usque ad summos 

 montes ascendens. 



Also a common European insect, and one which is very widely 

 spread over these Atlantic Groups where most probably it is uni- 

 versal. It occurs usually in the dung of cattle, but likewise under 

 vegetable refuse generally, from the sea-level to the summits of the
