374 LEPIDOPTERA. 



middle is a very faint paler cloud along the dorsal margin ; 

 before the fissure a large crescent-shaped but ill-defint^l 

 ochreous cloud ; cilia dark brown. Hind wings broadly sub- 

 divided, all three lobes alike, golden-brown with cilia hardly 

 darker ; legs dull brownish-white streaked with white and 

 dark brown. Female similar but stouter, and usually a 

 little paler. 



On the wing at the end of -lune and in Jul}'. 



Larva moderately stout, tapering towards the anal 

 extremity ; head smaller than the second segment, whitish 

 tinged with green, crown, sides, and a spot on each lobe 

 shining black ; mandibles blackish-brown ; body green, seg- 

 mental divisions paler; dorsal line bluish-green; raised 

 dots black, each with a moderately long grey hair and a tuft 

 of whitish bristles ; legs and prolegs semi-transparent, dotted 

 with grej'. (R. South — condensed.) 



May and June on Ononis arvcnsis and 0. siiinoaa (rest- 

 harrow), feeding on the young leaves at the top of a shoot. 

 Resting on the leaf, to which from its colour and downy 

 appearance it bears an accurate resemblance. 



Pupa at first light whitish-green, later pale brown ; covered 

 with thorn-like bristles. (Frey.) Attached by the tail to the 

 surface of a leaf of the food-plant. 



The moth hides during the day in the thick masses of rest- 

 harrow, flying lazily to a distance of a few feet if disturbed iu 

 hot sunshine, hardly moving when it is chilly. It flies over 

 this plant at dusk, either on the slopes of chalk hills, chalky 

 banks and commons, or in sandy spots on the coast. It is 

 peal, but sometimes very abundant where it occurs, in Kent, 

 Sussex, Surrey, Dorset, Devon, Wilts, Berks, Oxfordshire, 

 Herts, Essex and Cambridgeshire ; found sparingly in one 

 portion of the Norfolk coast near Hunstanton ; also in Here- 

 fordshire and ^Vorcestershire, and ^Mr. Arkle records it at the 

 Leet, Denbighshire ; but I have no knowledge of its existence 

 elsewhere in the United Kingdom. Abroad it is common
