much clouded and shaded with black, purplish, and ochreous, 

 in which, toward the apex, is usually a large ovate, or more 

 extended, pale space shaded with grey or reddish ; costa 

 spotted or clouded with black ; hind margin beyond the 

 subterminal line smoky-brown or shaded with black, in 

 which is a marginal row of triangular black dots ; cilia 

 grey dusted with white. Hind wings rounded, not elon- 

 gated, pale greyish-brown, almost white at the base, darker 

 brown toward the hind margin ; nervures also darker ; cilia 

 white. Female stouter, otherwise quite similar. 



Underside of the fore wings shining pale grey or ashy- 

 white, tinged toward the costal margin with brownish-purple ; 

 reniform stigma indicated by a darker streak ; hind wings 

 whitish, broadly dusted with brown along the costal region 

 and on the nervures ; central spot small, dusky black ; legs 

 dark brown barred with white ; leg tufts and body whitish- 

 brown. 



Not very variable, but having fixed climatal races; 

 specimens from the southern districts being of full size, with 

 the clouding dark purple-brown and rather extended ; those 

 from northern hill districts, and especially from Scotland, of 

 rather smaller size, with the costa of the fore wings straighter, 

 and the clouding somewhat lighter and more tinged with 

 red. In Ireland very rich, but evanescent, colouring seems 

 to be assumed. Mr. W. F. de V. Kane records an example 

 taken at Sligo which was wholly suffused with rose-colour ; 

 and Mr. C. A. Watts found one, freshly emerged, in 

 the Mourne Mountain district, Down, which showed a strong 

 suffusion of pink over the dai'ker area, and of green over 

 the basal area, anal angle, and reniform stigma. After 

 death these colours gradually faded, and when it was 

 forwarded to me they were only just traceable. In both 

 northern and southern specimens the oblique pale stripe is 

 occasionally interrupted in the middle by a dark cloud. 



On the wingf in June.
