212 LEPIDOPTERA. 



Larva rather slender, dull pea-green ; head light ochreous 

 with a black dot on either side ; dorsal plate broad, dark 

 green ; si^iracular region and raised dots paler ; anal legs 

 pale green. 



Jnne till August, on PofcntiUa tormcntilla, P. anserina, 

 Smyrnmm olusatrum, Mentha sylvestris, Valeriana, and many 

 other herbaceous plants, preferring the flowers ; also on 

 Mijrica gale and sallow. 



The male moth flies in the sunshine both in the morning and 

 afternoon, but especially at midday, the female at the same 

 time sitting on the tops of heather or other herbage close by. 

 It, however, often seems to prefer open land near the moun- 

 tain heaths, and the broad rough roads and paths leading to 

 them, to the moors themselves, and here the larva is con- 

 stantly to be found. The moth is said to settle down about 

 4 P.M., and it is not clearly understood that there is any later 

 flight. 



Locally plentiful on and near moors in Lancashire, 

 Cheshire, Yorkshire, Westmoreland, Durham and Northum- 

 berland, and on coast sandhills in the two latter counties. 

 In Wales recorded from Carnarvonshire ; in Scotland in 

 the Edinburgh district, Fife, Perthshire, Aberdeenshire, 

 Dumbartonshire, Lanark, Renfrew, and the Shetland Isles ; 

 in Ireland in Antrim, Armagh, Sligo, and Enniskillen. 

 Abroad it i.s found in the hill districts of Central Europe, 

 Sweden, Livonia, and Finland.

 of fore wings not folded, but the edge slightly rolled back; 

 hind wings rather smooth beneath. 



I. D. grotiana, Fab. — Expanse | inch (IG mm.). Fore
