The more usual form of the male and the female are shown on Plate 105 (Figs. 7[male], 8[female]). The colour varies from pale brown to a whitish or greyish brown tint in one direction, and to reddish or blackish brown in another. The cross lines, generally well defined, are sometimes absent, or nearly so, in some of the pale forms, and much obscured in the dark forms. The black outlined reniform and orbicular stigmata are sometimes obscured by a blackish cloud; the pale-centred, club-like mark below them varies in length, and is occasionally reduced to a small spot. "_Noctua subfusca_," Haworth, has been determined by Mr. E. R. Bankes, who possesses the type, to be an obscurely marked fuscous [male] example of this species. The greyish brown, rather rough-looking caterpillar, is freckled with a darker tint above, and inclined to greenish below; a fine, pale line along the middle of the back is edged with brownish, and on each side there is a pale line, edged above with brown, and below this a double pale line; head marked with blackish (Plate 109, Fig. 1). It feeds from March to April, after hibernation, on various low-growing plants, including goose-foot (_Chenopodium_), persicaria, knotgrass, dock, and clover. The moth is on the wing in June and July, and very occasionally in September. It is rather a common insect in eastern and southern counties bordering the sea, but extends into Surrey, and occasionally into Cambridgeshire, Oxfordshire, and Berkshire; and is also found more or less frequently in Herefordshire, Warwickshire, Staffordshire, Cheshire, Lancashire, and Yorkshire. In Scotland it occurs in Ayr, and on the eastern side to Moray. It has been taken in various {204} counties, on the coast, of Ireland from Cork to Sligo, and from Wicklow to Derry. THE LIGHT FEATHERED RUSTIC (_Agrotis_ (_Euxoa_) _cinerea_). Both sexes are shown in their typical forms on Plate 105. The fore wings of the male (Fig. 9) are generally pale greyish in colour, with blackish cross lines and central shade; the claviform mark is absent, and the orbicular stigma usually so, or represented by a dusky dot; sometimes the ground colour is brownish, occasionally purplish grey, and very rarely black. The female (Fig. 10) is smaller, and always much darker. The caterpillar is blackish green or dark greyish, with three fine pale lines, the central one edged on both sides, and the others edged above, with a darker tint; a pale stripe along the black spiracles; head, and plate on first ring black. It feeds on wild thyme, and is said to eat dock. It hatches from the egg in late June or early July, and presumably hibernates when full grown, as it does not seem to feed again when it reappears in early spring.
