The Purple Hair-streak is rather smaller than the last 

 species, rarely expanding more than an inch and a half across 

 the wings. 



The male is purplish-blue above, with a narrow black 

 border. The female is brown, with a rich purple blotch 

 reaching half across the front part of the fore-wings, and 

 beneath nearly to the hinder angle. On the under side the 

 wings are of a light silky grey, traversed by a continuous 

 undulating white streak, edged with brown anteriorly; be- 

 yond this there is a double row of faint whitish crescents, with 

 a few dusky dots on the fore-wings, and the hind-wings are 

 ornamented with two fulvous spots, one at the anal angle, and 

 the other forming an ocellus with a yellow iris and a black 

 pupil. The Butterfly appears in July and August.
