when at rest, the anterior pair nearly linear, the 

 hinder pair of a similar shape and very slender, all 

 of them with a very long fringe. Twenty-five 

 British species have heen described, one of which 

 is represented on the adjoining plate. It expands 

 ahout three lines and a half; the anterior wings 

 white, having a short ash-coloured hand at the base, 

 a rectangular one near the middle, hoth of them 

 edged with dusky and glossed with golden-yellow ; 

 and towards the apex there is a cruciform mark of 

 a similar colour, and a minute eye-like spot, with a 

 black oblique pupil at the tip. The hinder wings 

 are white, inclining to cinereous. 



Apparently not generally distributed : it has oo 

 tarred near London and elsewhere.
