350 LEPIDOPTERA. 



cloudy red-brown blotch of a ragged or broken triangular 

 form ; hind-marginal line red-brown ; cilia reddish ochreous. 

 Hind wings and their cilia smoky white. Female decidedly 

 smaller, yet stouter, the fore wings more narrowed and 

 suffused with red-brown. 



Underside of the fore wings light leaden-brown, the 

 margins dappled with orange. Hind wings smoky white. 



Rather variable in the depth of the ground colour, and in 

 the extent of the red-brown markings and clouding. 



On the wing in July and August. 



Larva slender, cylindrical, active, yellowish-green, or 

 bluish-green, with the under parts yellowish ; head and 

 plates light brown, the latter sometimes black-margined, 

 or else shining green. 



May and June; on Potentilla tormcntilla, P. reptans, F. 

 anserina, Spircea ulmaria, S. filipendula, Poteriuni snnguisorha, 

 Rosa spinosissima, Comarum palustre, Alchemilla vulgaris, 

 and Helianthnnum vulgare, folding the leaflets together, or 

 drawing together the leaves, and feeding within. Pupating 

 in the larval habitation. 



The moth is very plentiful on the chalk hills of the south 

 of England and equally so on the mountains of Wales ; but 

 perhaps more so still in Fen districts, where its larva feeds 

 on meadow-sweet, about a fortnight earlier than that of 

 P. shephenlana . Quite lively in the day-time and easily 

 disturbed, also flying freely at night and readily attracted by 

 a strong light. Not usuall}- a wood-frequenting species, but 

 in localities such as already mentioned to be found, often 

 abundantly, throughout the United Kingdom, and especially 

 common on the hills of Wales. Abroad plentiful throughout 

 Central Europe, Dalmatia, Sweden, and even Iceland. 



Genus 17. CAPUA. 



Antennae notched and thickly ciliated ; palpi divergent, 

 slender ; costa of the fore wings deeply folded at the base ;
