The whitish band crossing the brownish fore wings is generally fairly wide, sometimes broad, but occasionally it is very narrow; the reduction in width is mainly the result of brownish suffusion of the outer half of the band, leaving the inner half white. Kane mentions a smoky form from Co. Derry, in which the band is absent, and refers this to ab. _unicolorata_, Gregson. In a specimen from Sligo in my series, the band is tinged with brownish throughout. The hind wings are usually smoky brown, with a paler central band, but in some specimens, referable to ab. _turbaria_, Stephens, the basal two-thirds are whitish. The moths also vary in size (Plate 83, Figs. 1 and 2). The caterpillar is pinkish-ochreous inclining to brown; three pinkish lines along the back, and a similar line along the blackish spiracles; a dark plate on the first and last rings. It feeds in the capsules, on the seeds, of red campion (_Lychnis_ {206} _dioica_), and will eat those of the white _L. vespertina_: July to September. When eggs can be obtained early, it is possible to rear moths from them in August of the same year. The moth is out in June and July, in some southern districts in late May. As it conceals itself during the day among its food plant, or other vegetation around, it may be put up therefrom by gently stirring the herbage; but it flies freely about sundown, and is then easily netted. The species is widely distributed over England, Wales, and Scotland, up to Moray. In Ireland it is local and not plentiful, and the same is the case in the North of England. SMALL RIVULET (_Perizoma alchemillata_). This species (Plate 83, Figs. 3 and 6) is exceedingly close to the last mentioned, but in a general way it is to be distinguished by its greyish-brown coloration. A stippled whitish stripe before the central band, usually only faintly indicated in _affinitata_, is fairly distinct as a rule. Although the outer edge of the central band is rather more irregular, the middle tooth is not so prominent as in _affinitata_. The rather plump caterpillar is purplish above and yellowish green below; three yellow lines on the back, the central one broad; the spiracles are black, and a little above them is another yellow line; head, black and glossy, and there are black shining plates on the first and last rings of the body, that on the first ring divided by the yellow central line (adapted from Porritt). It feeds, in August and September, in the seed capsules of hemp nettle (_Galeopsis tetrahit_), sometimes on the rarer _G. ladanum_, and is said to eat woundwort (_Stachys_) occasionally. The moth is out in June and July, and, as in the case of the last species, may be stirred up from among its food plant or the surrounding vegetation, in lanes, and around wood borders. The species is widely distributed over the British Isles, except that it seems not to have been noticed in Scotland, north of Moray, although it occurs in the Hebrides. [Illustration]
