The caterpillar is green, inclining to yellowish or to brownish; some purplish-red marks and white-edged black spots on the back; the ring divisions are yellow, and there are reddish-brown or purplish-red marks on the sides; the markings vary. It feeds on birch, alder, and sallow, and may be beaten out at any time from July to September. The moth is out through the summer from May; its range in the British Isles is very similar to that of the last species, but it seems to have a preference for moist places. The distribution abroad extends eastward to Amurland, and a form known as ab. _schaefferi_, Bremer, occurs in the last-named country, and also in Corea and Japan. BARRED UMBER (_Numeria pulveraria_). Pale ochreous or reddish brown freckled with darker; the central dark reddish brown band is sometimes much narrowed below the middle; sometimes only the edges of the band are dark, the enclosed space being but little darker than the ground colour, or occasionally tinged with greenish; one example of the latter and two of the former were reared this year (1908) from larvae received in July, 1907, from Mr. F. Pope of Exeter; a male specimen bred from the same batch of larvae, but which emerged in August of the year last mentioned, is distinctly tinged with rosy over all the wings; the narrow band on the hind wings, not usually extended to the front edge, is in this specimen entire, whilst the greenish-banded specimen referred to above is without trace of a band on the hind wings. Two examples which are without locality, but which, I believe, came from the New Forest, have pale greyish-brown fore wings banded with brown in which there is a tinge of olive. Two examples of the male are figured on Plate 108. The eggs (Plate {269} 106, Fig. 2a) were pale greenish yellow when laid, May 17 to 20; the larvae hatched out from May 31 to June 2. The caterpillar, which is also depicted on the plate, is reddish brown, mottled with yellowish brown. It feeds on birch, sallow, ash, etc., from June to August. The moth, as a rule, does not emerge until the following spring, but sometimes specimens will come out the same year. Although widely distributed over nearly the whole of the British Isles, the species seems to be rarely met with in large numbers. The range abroad extends to Amurland, Corea, and Japan. BARRED RED (_Ellopia_ (_Hylaea_) _prosapiaria_).
