The moth is out in May and June, and specimens of a second generation are often not uncommon in August. It occurs in woodlands throughout England, but is most plentiful in the south. In Scotland, it appears to be local in Clydesdale, but is found thence up to Moray. In Ireland, only recorded from Galway (two specimens). CLAY TRIPLE-LINES (_Ephyra linearia_). This species (Plate 53, Fig. 13) varies in the general colour from yellowish to pale reddish ochreous; the cross lines are also variable, often the first is missing (Plate 53, Fig. 14), and not infrequently the dark central line is the only visible marking, but very exceptionally the central line is very little, if at all, more distinct than the normal first and second. The ringed white dots are rarely very conspicuous, and are often quite absent. The caterpillar is pale brownish, with a brown-edged yellowish line along the middle of the back, and some yellow-edged dark-brown streaks on the sides. In another form, the head is brown and the body green. It feeds in June, July, and again in September, on beech. The moth is out in May and June, and again in August and September. Beech woods are its favourite haunts, and it seldom strays far from them. It is generally common in the south, and its range apparently extends to Northumberland; but it is local and infrequent in the north. Three specimens have been recorded from Co. Galway, and one from Co. Cork, in Ireland. NOTE.--Nearly fifty years ago, at Brighton, a single specimen was reared from one of eight larvae that hatched from the same number of eggs deposited by a female _E. linearia_ that had paired with a male _E. orbicularia_. This hybrid has been named _brightoni_, Tutt. {138} THE MOCHA (_Ephyra annulata_). Normally, the wings of this species (Plate 53, Figs. 6, 9) are yellowish white, inclining to ochreous yellow with the blackish central shade near to and sometimes united with the blackish irregular and outwardly toothed second cross line on both fore and hind wings; the rings are deep brown or blackish. There is variation in the width and intensity of the central shade, and the rings sometimes are absent on the fore wings (ab. _obsoleta_, Riding), and occasionally all the wings are devoid of the annular mark (ab. _biobsoleta_, Riding). Examples of a second generation reared in captivity are rather deeper coloured, and have a sprinkling of black scales, chiefly on the fore wings. The caterpillar (Plate 51, Fig. 2, after Hofmann) is dark green, yellow between the rings; there are three yellow lines along the back, the outer ones waved; head reddish brown, paler marked. (Adapted from Porritt.) There is also a pale ochreous brown form.
