The caterpillar is green, sometimes tinged with pink on the first three rings; three brownish broken lines along the back, and a violet edged white line along the spiracles. It feeds on grasses, yarrow, groundsel, dock, plantain, gromwell (_Lithospermum_), and other low herbage; also on buds of hawthorn and sloe in the spring. October to April. The moth is out in August and September, sometimes later. It is found most frequently on the coast, perhaps, but occurs in Cambridgeshire, Hunts, Oxfordshire, Gloucestershire, Berks, Kent, Surrey, Sussex, Hants, and Isle of Wight; from Somerset to Cornwall; North and South Wales, Cheshire, Lancashire, and Yorkshire, and apparently in all counties northward except Westmoreland. Widely distributed in Scotland from the border to the Hebrides and Orkneys. It is found only on the coast in Ireland, and chiefly in the north-west. THE BLACK RUSTIC (_Aporophyla nigra_). This black or brownish black moth (Plate 137, Fig. 8) has the outer edge of the reniform stigma ochreous, and the cross lines are sometimes dotted with the same colour. The caterpillar is green, yellowish-brown, or dull purplish; first three rings often tinged with reddish; three darker, often broken, lines along the back; line along the black-edged white spiracles yellowish. It feeds on bedstraw (_Galium mollugo_), dock, plantain, grasses, etc. October to May. (The egg is figured on Plate 139, Fig. 3.) The moth is out in September and October. Chiefly a northern species, but it occurs in some of the southern counties. It is, however, most frequent in Northampton, Huntingdon, and Cambridgeshire; in Gloucestershire, {284} and Wales, and in the Isle of Man, Cumberland, and Westmoreland. In Lincolnshire, Yorkshire, and Lancashire it seems to be local or rare. It is found up to Moray in Scotland, and is sometimes plentiful in Aberdeenshire, Inverness, and Moray. Very local in Ireland, but Kane says that it is found in the extreme north, south, east, and west. THE FEATHERED BRINDLE (_Aporophyla australis_). The fore wings are pale grey, sometimes darker clouded, chiefly on the costa; the black cross lines, slender, wavy, but not always distinct; a short black bar from middle of the base and one below it on the inner margin; often two other bars, pretty much in a line with the basal ones, on the central area; a row of black wedges on the outer area, near margin. Hind wings white in the male, pale brownish grey in the female. Most of our specimens, perhaps all, are referable to var. _pascuea_, Curtis. The caterpillar is yellowish green tinged with reddish above; a pale reddish line along the middle of the back has black V-shaped marks upon it, and there is a series of black marks on each side; the line along the spiracles yellowish; head green, brown freckled. Feeds, from October to April, on grasses, catchfly (_Silene maritima_), etc. The moth, which is figured on Plate 137, Figs. 3, 4, is out from late August to October.
