1 86 LEPIDOPTERA. 



Underside of the fore wings dark smoky-grey, tinged with 

 purple, especially toward the hind margin, where is a broad 

 pale purplish-red band having a scalloped and sharply defined 

 inner edge ; a black spot on the costa commences a cloudy 

 blackish transverse stripe or shade. Hind wings white, 

 broadly dusted with purple-red along the costal, apical, 

 and one half the hind marginal regions ; central spot 

 blackish followed by a transverse row of dark brown streaks 

 upon the nervures, and beyond this by a smoky-grey trans- 

 verse stripe ; but lying along the hind margin is a sharply 

 pale space. Body and legs purple-brown. 



Usually extremely constant in colour, though there is 

 ordinarily a little variation in the general tone of purple- 

 brown colour and in the distinctness of the orange spot, but 

 Mr. Adkin states that specimens from the Scilly Isles are 

 more mottled, while in Ireland, according to Mr. Kane, 

 especially in the extreme West, the tone is dark brown with 

 only a trace of the orange spot, and the subterminal line 

 almost obsolete. In Dumbartonshire, Scotland, it is found 

 by Mr. J. R. Malloch of a very dark purple-brown with hardly 

 a tinge of the reddish colour remaining, but the orange spot 

 quite distinct and the markings well defined. In the col- 

 lection of Mr. H. J. Turner is an example having the W in 

 the subterminal line broadly suffused so as to form a bright 

 white blotch. 



On the wing in June and July, and occasionally, in a 

 second generation, at the end of August, or in September or 

 October. 



Laeva long, stout, smooth, cylindrical, rather tapering 

 to each extremity; head rounded, shining, pale brownish- 

 ochreous, or in the green forms pale bluish-green ; mouth 

 brown with a yellow projection on each side ; colour very 

 variable, pale brown, green, pink, ochreous, or pale brownish- 

 green, distinctly irrorated with white and having the seg- 

 mental incisions paler ; dorsal and subdors£il lines ill-defined.
