1 8.8 . LEPIDOPTERA. 



with black-brown ; dorsal blotch large, triangular, white 

 with faint brown lines ; central band of the ground colour, 

 closely followed by a parallel cloudy white band which joins 

 .the, also white, ocellus ; this last enclosing some black 

 streaks ; costa strongly dotted with twin white streaks ; 

 along the hind margin is a broken black line ; cilia white 

 with black tijDs. Hind wings and their cilia smoky-white. 

 Female similar. 



Underside of the fore wings pale leaden brown with 

 obscure paler costal dots. Hind wings leaden white. 



On the wing at the end of June and in July. 



Larva apparentlj"- un described, except that Mr. A. F. 

 Griffiths says that it is jDale yellowish, very transparent, with 

 a dark head. In September and October, and after hyberna- 

 tion feeding up in the spring on Arctostaphylos uva-ursi 

 (bearberry), raining in the younger leaves, eating out the 

 whole contents of the leaf, which thus resembles an empty 

 bladder, passing to another which, after uniting it with the 

 original leaf with silk, it serves in the same manner, and 

 continues the process till full fed. 



Pupa compact, abdomen curved forward, thorax, limb and 

 wing-covers shiny pale brown, abdominal segments pale 

 yellow-brown, not glossy ; cremaster short, blunt, glossy, 

 and furnished with minute hooked bristles. In the last leaf 

 mined out by the larva. 



This species flies in the sunshine about its food plants in 

 its mountain haunts. Mr. A. H. Jones states that he found 

 it, in equal numbers, among heather in the same localities. 

 These are in Scotland in Perthshire, Aberdeenshire, Inver- 

 ness and some parts of the Edinburgh district ; but it does 

 not seem to have been found in England, Wales or Ireland. 

 Abroad it inhabits Switzerland, Sweden, Norway, and 

 North-west Russia.
