The moth represented on Plate 117, Fig. 5, has the fore wings silvery grey clouded with brownish on the central area; or occasionally spreading over a larger portion of the wings, and sometimes purplish in tint. The caterpillar is brownish inclining to reddish, clouded on the back with paler and darker brown. The central line, which has a broken blackish edging, is only distinct on the front rings. Spiracles black; head pale brown marked with darker brown. In the autumn it feeds on low plants such as dock, plantain, etc.; but in the spring it is found at night on the young growth of birch and sallow bushes, and more rarely on hawthorn, and I believe, on bilberry. The moth which occurs in birch woods in June and July, is not uncommon in the south of England from Essex to Hampshire, and has been found in Dorset and Devonshire. It has also been obtained more or less frequently in Berkshire, Oxfordshire, Cambridgeshire (once), Huntingdon, Worcestershire (Wyre Forest and Malvern), Staffordshire (north), Lancashire (Witherslack), Yorkshire (Huddersfield, once), and Westmoreland. In Scotland it ranges on the west from Ayr to Argyllshire, but although local is more frequent in Perthshire, Moray, and Sutherland. Var. _obscurata_, Staud., is a form of this species occurring in Amurland and Southern Siberia. THE PALE SHINING BROWN (_Aplecta_ (_Mamestra_) _advena_). This moth (Plate 117, Fig. 6) is pale reddish brown and glossy, especially on the outer area, on the fore wings. The caterpillar {238} is pale ochreous brown above, and inclining to greenish below; three dark-edged pale lines, and a series of dark diamond-shaped marks on the back. The usual dots are whitish encircled with blackish, and the blackish edged spiracles are reddish brown; head olive brown, and plate on first ring blackish with the three lines showing distinct. From July to September it feeds on various low plants, including rest-harrow, dandelion, and knotgrass, also on broom, bilberry (Barrett); and Newman mentions sowthistle (_Sonchus_) and lettuce. In confinement the moth sometimes emerges in the autumn, but in the open it flies in June and July. Flowers seem to have more attraction for it than sugar. I have taken it at the blossoms of wood sage, white campion, and woundwort (_Stachys_), and Barrett notes, bladder campion, viper's bugloss, and the martagon lily. The species is chiefly found, as regards England, in the southern and eastern counties; and in the Solway, Clyde, Forth, and Tay districts of Scotland. Louth is the only Irish county from which it has been reported. The range abroad extends to Amurland. In North America the species is represented by var. _purpurissata_, Grote.
