The early stages are shown on Plate 48, Figs. 2-2b. The eggs, when laid on June 18 and 19, were whitish-green, but soon turned pinkish, inclining to coral red. The caterpillars hatched July 3 to 6, and were reared on a diet of privet leaves--a food that I have always found they preferred to any other that has been offered to them, and upon which I have found them in the open. They are exceedingly easy to rear, and if, as sometimes happens, they refuse to feed up and get through to the moth state in {130} September of the same year, they do not die off during the winter or early spring, as do so many larvae of other hibernating species. Enclosed in a suitable receptacle, such as a roomy glass cylinder, with some twigs of privet plugged in a bottle of water, the caterpillars may be left in any odd corner until spring, when fresh twigs should be introduced from time to time. Other food plants are dock, groundsel, dandelion, knotgrass, bedstraw, etc. In colour the caterpillar is pale ochreous brown, with three darker brown lines on the back, the central one broken on the front rings, and the others edged above with whitish; the spiracles are black, and the stripe along the side pale drab. The moth affects hedgerows, banks, bushy places on rough sloping ground, and sandhills by the sea. It flies in the evening, and may be met with in July and August, sometimes in September, in most English and Welsh counties, and in the south of Ireland. It is local and somewhat rare in Northern England, and seems not to occur in Scotland. TAWNY WAVE (_Acidalia_ (_Leptomeris_) _rubiginata_). This attractive little moth (Plate 50, Figs. 1, 2), known also as _rubricata_ Fab., varies in colour from ochreous brown with a purplish or reddish tinge, to purplish brown or crimson; the first line of the fore wings is curved, and the second is parallel with the central shade. Sometimes the space between the last two lines and between the first and second lines of the hind wings is paler than the general colour. A dusky brown form has been recorded from boggy heaths in Norfolk. The roughish caterpillar, which gradually tapers to the notched head, is greyish inclining to yellowish or greenish; three blackish lines on the back, the central one widened on the middle rings, and the others only distinct on the front rings; a black-edged pale line above the black spiracles, and a dusky stripe below them (Barrett). It feeds from August to May on clover, trefoil, {131} knotgrass, etc. Sometimes as a second generation in June and July.
