colour; of the female the anterior wings are more of an ashy hue, less 

 freckled with pale dots, especially on the disc, which last is clouded with 

 fuscous, and bears one or two irregular and interrupted black streaks, the 

 longest one terminating in a conspicuous white dot; posterior wings in 

 both sexes immaculate; legs dull tawny, four anterior annulated with 

 fuscous. 

 The markings on the anterior wings vary considerably in intensity, and are 

 sometimes nearly obliterated. 



Rather local, but in some places very abundant, especially about 

 Albury in Surrey, in June and the beginning of July ; also taken at 

 Ripley, Hertford, in the New Forest, and in Devonshire.
