is a whitish stripe ; snliterminal line slender, repeatedly 

 indented, purple-brown, thickened on the costa, in the 

 middle, and above the anal angle into, in each, case a broad 

 purple-brown streak or blotch; orbicular stigma large, 

 irregular, extended at the upper edge, whitish margined with 

 black ; reniform stigma silvery-purple edged with black and 

 containing two purplish lines ; claviform stigma purplish, 

 edged with black ; space between the two upper stigmata 

 purple-brown, and all the remaining space between the first 

 and second lines clouded and shaded with the same ; extreme 

 hind margin edged with black lunules, the thickest of which 

 are at the anal angle and are edged inside by two small 

 purple-brown clouds within the large cur\ed streak on the 

 subterminal line ; cilia silvery-white tinged with grey. 

 Hind wings pale smoky-brown, with a large darker central 

 lunule followed by a still darker slender transverse stripe ; 

 hind margin broadly dark smoky-brown ; cilia white, and a 

 whitish submarginal streak lies along within the anal angle. 

 Female stouter, rather larger, witli broader fore wings, but 

 extremely similar. Underside of the fore wings pale smoky- 

 brown, silvery-grey along the costa and hind margin, and 

 with a silvery-white transverse line near the latter ; a faintly 

 white transvei'se band lies beyond ' the middle of the wing 

 and before it a smoky-black costal spot ; at the middle of the 

 base is a raised tuft of pale orange scales. Hind wings 

 shining whitish, much dusted with smoky-brown on the 

 costal margin and the nervures ; central spot large, ovate, 

 blackish ; beyond it is a slender blackish cloudy transverse 

 stripe followed by a broader stripe of dusky atoms nearer 

 the hind margin. Body smoky-brown thickly dusted with 

 white ; legs brown : leg tufts white. 



Usually not variable except in a small degree in the 

 extent of purple-brown clouding, which in some instances 

 extends itself broadly over the fore wings, in others is re- 

 stricted to only a portion of the central space : but there is 

 also some local variation, specimens from Scotland having
