124 LEPIDOPTERA. 



costa and hind margin edged Avith white. Hind wings 

 leaden white. 



On the wing in June and July. Hofmann says also in 

 September, but this seems not to be the case here. 



Larva of a gelatinous shining appearance and nearly 

 colourless, with a grey intestinal dorsal marking on the 

 first body-segment, and on each side a more distinct spot. 



September, in folded leaves of the pointed foliaged willows 

 and sallows, sometimes broadly folding the edge of the leaf. 

 Sorhagen says, " from July in pod-shaped, spun-together 

 leaves of 8alix repens and other small-leaved sallows.'' 



Rather a lazy sluggish species, sitting during the day in 

 sallow bushes, especially SaJix caprca, when disturbed flying 

 but a very short distance, and usually to the ground, where 

 it hides among grass or dead leaves. At sunset it is out on 

 the wing of its own accord, but then darts about so sharply 

 that it is not very readily captured, and being nowliere plen- 

 tiful usually figures as an uncommon species in collections. 

 Nevertheless, it is very generally distributed with us, found 

 in Kent, Sussex, Surrey, Hants, Dorset, Wilts, Berks, Herts, 

 Hunts, Cambs, Essex, Norfolk, Gloucestershire, Hereford- 

 shire, Leicestershire, Cheshire, Lancashire, Yorks, and West- 

 morland ; but I know of no localities elsewhere in the 

 United Kingdom. Abroad it is distributed over Central 

 Europe, Northern Italy, Spain, Portugal, and Norway. 



12. A, mitterbacheriana, Schiff. — Expanse | inch

 with a large, straight-edged, chocolate red basal blotch which 

 does not reach the costa.
