214 BRITISH BUTTERFLIES AND MOTHS 



throughout England and Ireland, and also occurs in the 

 west of Scotland. 



The expansion of the wings is about 1 J inch. The 

 fore-wings are greenish-grey, with two transverse darker 

 lines, rather faintly indicated, and sometimes the inter- 

 vening space is a little darkened ; towards the costa is 

 a small, dark, central spot ; towards the hind margin is 

 a wavy pale band; the hind-wings are rather paler, 

 with faint indications of a transverse dark line and pale

The larva is dark green, with the dorsal line darker, 

 and the subdorsal lines paler ; the spiracular line is 

 pinkish-white, and has a branch from it running down 

 the third pair of legs ; the head is bifid, and the front 

 edge of the second segment is also bifid, with the tips 

 dark red. It feeds on broom and Genista Anglica in 

 May and June. 



The perfect insect appears in July, and is readily 

 started up as we walk along on the heathy places where 

 it occurs ; it flies freely at dusk, and occasionally comes 

 to light.
