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
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.
The Grey Arches (Aplecta (Mamestra) nebulosa).
Grey of some shade is the more general hue of this species, but it varies in the West of England and in Ireland to white (var. pallida, Tutt), and this form is shown on Plate [119], Fig. 3. In Cheshire (Delamere), Lancashire (Warrington), and South Yorkshire black or blackish forms occur, and two examples of this melanic race are portrayed on the plate, Fig. 4 being var. robsoni, Collins, and Fig. 5 var. thompsoni, Arkle. Over the greater part of England, and in Scotland, the greyish form is most frequently met with, but the white form has been found in Argyllshire and in Sutherland. The caterpillar is ochreous brown or brownish grey, with a series of diamond-shaped blackish marks, and a pale central line, on the back;
the dots and the spiracles are black, each of the latter with a blackish streak in front of it. In the autumn it feeds upon dock and other low plants; but in the spring, when it is more easily found, the caterpillar eats the buds and young leaves of birch, oak, sallow, bramble, etc. The moth is out in June and July, and is not uncommon in woods. The black form seems to be peculiar to north England. In Amurland the species is represented by var. askolda, Oberthür, and in North America by var. nimbosa, Guenée.
The Cabbage Moth (Barathra brassicæ).
The darker markings of this very common greyish moth are often very obscure, but the white outline of the reniform stigma, and the white submarginal line are usually distinct. The caterpillar varies in colour, but generally is some shade of dull brown or greenish, with the usual dots greyish or green tinged. The central line on the back is dusky, speckled with white, and the stripe low down on the sides is yellowish, greenish, or dingy brown; head ochreous brown marked with darker or greenish. Although it is exceedingly partial to the cabbage and other plants of the kind, it will feed upon almost every sort of low herbage, wild or cultivated. Barrett states that it has been found feeding on oak. I have taken it from birch in the garden, and it is known to eat leaves of almost any tree or shrub that may be offered to it in confinement. July to October. The moth is out in June and July, and sometimes there is an emergence in September. The species occurs over the whole of the British Isles, and abroad its range extends to India, Amurland, and Japan. (Plate [120], Figs. 3♂, 6♀.)
The Dot (Mamestra persicariæ).
The striking feature of the bluish-black moth shown on Plate [120], Figs. 1, 2, is the brownish centred white reniform
