hatch in February or March, and the larvse become full fed 

 in June. 



Pupa smooth, not shining, rounded — the dorsal portion 

 especially so ; wing cases long and prominent ; dull green, 

 with a dark brown dorsal line, consisting of arrow-head 

 marks. June, July. 



A very quiet little butterfly, not particularly active ; espe- 

 cially frequenting hollow spots on sandy heaths, but occurring 

 in other sandy places where its food-plant is plentiful. 



Apparently found in all the southern half of England, and 

 in Wales, wherever suitable localities occur ; most plentiful 

 iu the heathy districts of Dorset, Hants, Surrey, and Berk- 

 shu-e ; common in Norfolk and Suffolk ; scarce in Gloucester- 

 shire and Somersetshire ; extending to Yorkshire and Lanca- 

 shire, though not commonly ; and even recorded from beyond 

 the Pass of Killiecrankie, and from Rannoch, in Perthshire. 

 In Ireland, where localities suitable for it abound, it appears, 

 singularly enough, to be very scarce and local. Mr. Birchall 

 records it from the Murrough of Wicklow and from Rostrevor. 



Widely distributed over nearly the whole of Europe and 

 a large portion of Asia.
