a light suffused double band, and with ncrvule 5 rising from the hinder half of the discocellular 

 nervtde. 



*96. L. Decolorata (Hiibn.). — Fore-wings pale brownish-yellow, waved with rusty-brown, the 

 central area with two large rusty-brown projections in cells 2 and 3, the second double stripe white 

 in its broad front half, almost interrupted, and with the narrower hinder half yellowish ; the 

 subterminal line shaded with rusty-brown in front, and the hind-wings whitish, and suffused 

 with yellowish towards the hind margin. Expands from i to \\ inches. Common in Europe 

 and the Altai in June and July. The larva feeds in the seed-capsules of the red campion from 

 July to September. 



* 97. L. Albulata (Steph.). — Fore -wings pale greyish-yellow (grey in variety Griseata, Staud.), 

 waved with dusky, the double stripes white and equally divided, the central area with a slight 

 double projection in the middle, and with no central dot ; the subterminal line white and shortly 

 dentated ; hind-wings whitish, with the hind margin grey. Expands about three-quarters of 

 an inch. Common in Europe in June. The larva is thick, whitish-green, with dark green stripes 

 on the back and sides. It feeds in the seed-capsules of Rhinantlius from July to September. 



* 98. L. Blandiata (W. V.). — Fore-wings grey, the central area blackish, at least on the 

 costa, with a black central dot, and a slight double projection in the middle, bounded by two 

 broad and equally divided white bands ; the subterminal line white, dentated, and spotted 

 with blackish behind in cells 5 and 6 ; hind-wings clouded with grey, and with the hind margin 

 darker. Expands about three-quarters of an inch. Common in Northern and Central Europe 

 in May and June. The larva is thick, green, with dark red triangular spots on the back, and 

 a yellowish-green stripe on the sides. It feeds on Euphrasia officinalis in September. 



*99. L. Minorata (Tr). — Resembles Blandiata, but the double stripes are not so broad, 

 and the front half of the second stripe is narrower and pure white, and the hinder half is 

 somewhat clouded ; the central and marginal areas are varied with dark grey, the central dot is 

 surrounded with whitish, and the hind-wings are pale grey. Expands from one-half to three- 

 quarters of an inch. Inhabits mountainous districts in Northern and Central Europe in June 

 and July, flying by day. 



* 100. L. Unifasciata (Haw.). — Fore-wings fawn-coloured in the basal area and before the 

 subterminal line ; brownish-grey before the hind margin, and the central area dark greyish- 

 brown, with a moderate projection in the middle ; the two double bands unequally divided, and 

 always composed of a white line in the central area, and a broader pale reddish-grey stripe ; the 

 subterminal line spotted with white behind below the costa, and the hind-wings grey. Expands 

 about three-quarters of an inch. Local in Central Europe from June to August. The larva is 

 short, clay-coloured, with interrupted brown lines on the back, and a continuous whitish line 

 on the sides. It feeds on Odontites lutca in October, and constructs a small solid cocoon, in 

 which it is said to remain for two years before the moth emerges.
