Habitat per margines rivulonim Fuerteventiu-ae, tunc inde vulgaris. 



The A. albipes, which abounds throughout the greater portion of 

 Europe, and is universal in damp spots at Madeira, and which I have 

 received also from the Azores, appears (so far as observed hitherto) to 

 be confined at the Canaries to Fuerteventura, where it is common at 

 the edges of the few small streams which that barren island produces. 

 It was first found by Mr. Gray and myself at La Antigua (on our 

 way from Agua Bueyes to Port Cabras), on the 28th of January 1858 ; 

 and during April of the following year I took it abundantly in the 



Rio Palmas.

Habitat Canariam, TeneriflPam et Gomeram, bine inde baud in- 

 frequens. 



The common European A. marginatus (which occurs, though rarely, 

 in Madeira, and which is recorded by M. Morelet at the Azores) is 

 tolerably abundant in certain localities at the Canaries, though at 

 present I have myself observed it only in the islands of Grand 

 Canary and Teneriffe. In the former I took it at Arguiniguin (along 

 the edges of the small pool, or lake, close to the sea) ; and in the latter 

 (from whence it has also been communicated by the Barao do Castello 

 de Paiva) in moist spots near S*" Cruz and at Ycod el Alto. It has 

 however been met with, more recently, by Dr. Crotch, in Gomera.
