Europe to Lapland, and in Frauce, Germany, Austria, 

 Switzerland, Northern Italy, Ualmatia, the Ural Mountain 

 district, Tartary, and the mountainous regions of Central 

 Asia. 



[A. strigaria, Hiih. — A species of nearly the size and 

 shape of the last, but with the fore wings a little more 

 pointed ; the colour very pale brownish-ochreous, or 

 brownish-white, and the transverse lines ochreous brown, 

 more distinct and more oblique ; the discal and central dots 

 small and obscure, black. The capture of two specimens of 

 this species, in Kent, was recorded in the Entomologists 

 Annual for 1871 ; but serious doubts arose as to the authenti- 

 city of the statement, and no confirmatory evidence has since 

 been obtained. There is not the slightest reason to believe 

 this species to be an inhabitant of these Islands, though 

 elsewhere it is widely distributed in Europe and Northern 

 Asia.]

 wings greyish-white, faintly tinged with ochreous, and 

 slenderly dark-margined ; lines sinuous, the second angulated 

 below the costa ; sometimes the space between the second

 palpi very small, reddish-brown, hardly concealing the 

 tongue; face smoothly convex, chocolate colour, edged by a

 drab; thorax and abdomen slender, of the same colour; anal 

 tuft compressed. Fore wings rather elongated ; costa straight 

 t-o beyond the middle, thence very much arched ; apex

 white, dusted with grey, and shaded with ochreous, or tinged 

 with reddish-brown ; first line obscure, oblique, pale smoky-
