THE LARGE RANUNCULUS (_Polia flavicincta_). The fore wings of this moth (Plate 138, Figs. 6 and 7), are pale grey, clouded, and marked with darker; yellowish freckles at the base, and on the central area and the submarginal line are usually, but not always, present. Sometimes, chiefly in northern specimens, these wings are much suffused with darker grey, approaching blackish. The caterpillar is green with a yellowish or bluish tinge; a dusky line along the back, and a dark green line along the black-edged white spiracles. It feeds on dock, groundsel, plantain, and many other plants from April to July. The moth flies in September and October, and, except in Kent, and perhaps Sussex, is rather uncommon in the southern counties of England. It occurs, however, not infrequently in the eastern counties, and through Oxford, Berks, Gloucester, Somerset to Cornwall, and northward through Hereford and parts of the Midlands to Lancashire, Yorkshire, and Durham. THE GREY CHI (_Polia chi_). Four specimens are depicted on Plate 138. Figs. 2 and 3 represent the sexes of the type form, and Figs. 4 and 5, the greenish-grey var. _olivacea_, Stephens. Both forms may be paler or darker, but the green tinge is apt to fade out. Var. _suffusa_, Tutt, is a dark greyish suffused form. {287} The caterpillar is green, inclining to bluish green above; the lines on the back are whitish, edged with dark green; that along the black-margined white spiracles is white, shaded above with dark green. It feeds on dock, dandelion, groundsel, etc.; also on sallow and hawthorn, from April to June. The moth is out in August and September. It prefers the open country to woodlands, and is often seen resting on rocks, stone, or other walls, and buildings. Except that it occurs in Devon and Dorset, the species seems to be absent in the south of England, but its area of distribution extends in the British Isles from the Midlands of England to Moray and Ross in Scotland, and to Ireland. THE BLACK-BANDED (_Polia xanthomista_). The form of this species occurring in Britain is var. _nigrocincta_, Tr. (Plate 140, Figs. 2, 3), which is pale grey, spotted with white, and clouded on the central area with black. The typical yellow flecking and dotting is in this form usually sparse, but occasionally it is prominent. A specimen reared from a caterpillar taken in the Isle of Man was suffused on the fore wings with bright orange.
