STAPHYLINID^E. 461 



extensive series is now before me, captured by the Messrs. Crotch 

 near Las Palmas in Grand Canary. The Canarian specimens seem 

 to be a trifle smaller than an English type which has been commu- 

 nicated by Mr. Bye, and the Fuerteventuran ones have their legs 

 more pallid ; but such differences, even if constant (which is ex- 

 tremely doubtful), would scarcely suffice to indicate even a geogra- 

 phical variety ; and I have therefore no hesitation in referring the 

 species to the H.plumbea. 



1267. Homalota granulosa, 



Homalota granulosa, WolL, Ins. Mad. 548 (1854). 

 , Id., Cat. Mad. Col. 174 (1857). 



Habitat Maderenses (Mad.'), in aquosis sylvaticis editioribus raris- 

 sima. 



Observed hitherto only in Madeira proper, where it would appear 

 to be extremely rare, occurring in wet places, at a lofty altitude, 

 within the sylvan districts. 



1268. Homalota obliquepunctata. 



Homalota obliquepimctata, WolL, Ins. Mad. 549 (1854). 

 , Id., Cat. Mad. Col. 174 (1857). 



Habitat Maderenses (Mad.), inter lapillos per margines rivulorum in 

 intermediis vulgaris. 



Rather a common species at intermediate elevations in Ma- 

 deira proper, where it resides under wet stones and shingle at the 

 edges of the streams ; but it has not yet been observed in any of 

 the other islands. 



1269. Homalota amnicola. 

 Homalota amnicola, Woll, Cat. Can. Col. 536 (1864). 



Habitat Canarienses (Can., Ten., Gom., Palma, Hierro), in aquosis 

 intermediis et preecipue inter lapillos per margines rivulorum 

 sese occultare delectans. 



Found in exactly the same sort of places as the H. obliquepunctata, 

 but at the Canaries instead of Madeira. Indeed, although certainly 

 distinct from it, it may be regarded as the Canarian representative 

 of that species to which, both in general aspect and its subaquatic 

 habits, it is closely allied. It has been taken in Grand Canary, 

 Teneriffe, Gomera, Palma, and Hierro ; and it is more abundant by 

 the streams of intermediate altitudes, within the sylvan districts,
