meu silvery-white. Fore wings rather narrow, blunt ; costa 

 flatly arched, without fold ; dai'k red-brown, with a silvery- 

 white narrow stripe between the oblique basal blotch and 

 the central band ; beyond the latter is another silvery-white 

 stripe from the costa curving off toward the apex, where it 

 joins some white dusting, often passing on to the anal angle ; 

 cilia brown, intersected with silvery-white. Hind wings 

 narrow, smoky white ; cilia paler. Female similar bat with 

 the silvery white markings broader. 



On the wing in July and August, and in a second genera- 

 tion in October, and after hybernation in April and May. 

 The individuals of the summer generation are large and often 

 more yellow in colour. 



Larva green with paler raised dots, which are scarcely 

 visible to the naked eye ; head and legs pale green. (Hof- 

 mann.) 



June and July, and a second brood in September, on 

 heather, whortleberry, sweet gale, wild basil and other low- 

 growing plants, even columbine ; but most attached to heathy 

 laud.

 hybernation. It creeps up from the heath towards sunset, 

 or earlier on warm aftei-noons, and flies about for a short 

 time or sits on the tops in the sunshine. Generally distri- 

 buted and often common, on heaths, moors, and mosses 

 throughout the country, probably all over the three king- 

 doms, but records are insuflicient. Abroad it is found over 

 the greater part of Europe, and in Bithynia ; also in North
