TOO LEPIDOPTERA. 



another over the anal angle, and very often preceded by 

 another, smaller, near the base of the wing ; sometimes 

 these are shaded with brown lines, or filled up with velvety, 

 dark brown clouding; or, on the other hand, they are united, 

 and form an irregular stripe extending the whole length of 

 the dorsal margin, and often occupying one-half the breadth 

 of the wings ; costal dots either very minute or absent ; 

 <;ilia dark brown. Hind wings clear light smoke colour, 

 cilia more tinged vvith red. Female similar, but without the 

 costal fold. 



Underside of the fore wings reddish brown marbled with 

 black. Hind wings pale lead colour. 



Very variable in colour, the darker portion often varied 

 with different shades of brown, the dorsal pale portion with 

 ochreous or grey. It is always recognisable by the squared 

 hinder portion of its narrow fore wings. 



On the wing in March and April. Abroad there are said 

 to be later emergences, in July, August, and September. 



Larva whitish or pale green ; the head pale brown. It 

 feeds on sallows and willows. (Mdme. Lienig.) Sorhageu 

 says that it feeds on both downy and glossy leaved willows 

 in June, July, and October. 



I have no personal knowledge of this species in a living 

 state. The late Mr. T. Wilkinson wrote : " I took them on 

 Seamu Moor, two miles west of Scarborough ; they were 

 freely on the wing on fine sunny mornings from 10 a.m. to 

 1 P.M., amongst heather, stunted oaks, birches, sallows, nut 

 bushes, and furze bushes ; they seemed to frequent the 

 sallows the most." The late Mr. J. B. Hodgkinson recorded 

 it in Westmoreland and North Lancashire "flying in the 

 afternoon." It seems with us to be confined to these 

 counties, Yorkshire, Durham and Cumberland, and in Scot- 

 land to Perthshire ; but there are curious records which 

 liave not been explained nor contradicted — one of a specimen
