THE COSMOPOLITAN. {305} In the typical form the fore wings are of a smooth soft honey colour, or colour of the honeycomb, having the nervures faintly perceptible, but not paler; a black discal dot, and two more dots with some faint blackish dashes indicate the usual second line. Tutt has named several forms, the most important being ab. _lutea_, bright yellow buff with discal dot and two dots beyond; and ab. _rufa_, deep reddish with discal dot and two others beyond. Besides these there are ab. _ænea_, Mathew, deep orange, with only one dot representing second line; and ab. _obscura_, Mathew, cinnamon-brown, with smoky shading between some of the nervures. The hind wings vary from whitish with darker nervures, to smoky grey; but the fringes always remain whitish. The caterpillar is a warm putty colour, or pinkish brown, mottled and shaded with darker shades; three pale whitish brown lines on the back, the central one bordered on each side by a darker shade, and the outer ones shaded inwardly with darker and edged below by a darker line; a brown or pinkish stripe above the spiracles, and a pinkish yellow stripe below them; head yellowish-brown, shining, and dotted with darker colour. It feeds on grasses from July to April (adapted from Mathew). The moth flies in June and July, and frequents the flowers of the large grasses growing on salt marshes. Sometimes specimens of a second brood appear in August or September. THE SMOKY WAINSCOT (_Leucania impura_). The range of this common species (Plate 147, Figs. 3[male], 4[female]), in the British Isles is almost the same as that of _L. pallens_, but it does not extend further north than Moray in Scotland. The hind wings are greyish or blackish grey. A form with reddish {306} fore wings is var. _punctina_, Haw., which sometimes has a row of black dots on the outer margin. The caterpillar is greyish ochreous above, greenish tinged beneath; a brown stripe along the middle of the back is intersected by a very fine white line; above the reddish black-edged spiracles is a brownish stripe; usual dots black; head pale brown, shining, netted with brown and lined with blackish. It feeds on grasses from August to May. The moth is out in July and August; rather later in the north. Distribution abroad extends to Amurland and Japan. THE SOUTHERN WAINSCOT (_Leucania straminea_).
