According to Stephens, who figured this species in 1831, a specimen was taken, near Dover, somewhere about 1825; he also refers to Yorkshire specimens, one of which he had in his collection. Since that time the species has been obtained in Lancashire (Ashton-on-Mersey), and it was noted, not uncommon from the first to third week in July, 1875, on low heathery ground at Winch Bridge, Upper Teesdale, Durham. Casual specimens have also been recorded from Folkestone, Kent; Hastings, Sussex, and South Devon. The last concerns a specimen taken in the Newton Abbot district in 1902. What may be termed the British home of the species is, however, the Breck sand district in the eastern counties, where, since 1860, it has been found in greater or lesser plenty, in June, each year up to the present time. The best known localities are Tuddenham, Brandon, Thetford, and Bury St. Edmunds. It sits among the vegetation in fields or the borders thereof, and also on heaths. Occasionally, it indulges in flight in the afternoon, but it is more often put up as the collector approaches its place of retreat. At night it is usually active, and light has a strong attraction for it. Abroad, its range extends to Amurland and Corea. THE SMOKY WAVE (_Acidalia_ (_Pylarge_) _fumata_). The sexes of this greyish-white moth are figured on Plate 50, Figs. 4 [male], 5 [female]. It will be seen that the female is smaller than the male. The caterpillar is very slender, and finely wrinkled; pale ochreous brown, with three pale lines along the back, each of which is shaded on both sides with brown. Beneath the ridge, low down along the sides, is a dark stripe, and the under surface is pale. It feeds on bilberry, sallow and heather, and will eat knotgrass, chickweed, and dandelion. Hatching in August, it {132} hibernates when nearly mature, but it resumes feeding in the spring. The moth is out in June and July, and frequents moors and mosses. Plentiful in Scotland and in the north of England, its range extends through Wales and the west of England to Devonshire, where it occurs on Exmoor and is common in some parts of that extensive area. In Ireland, recorded by Birchall as widely distributed; Kane notes it from counties Kerry, Waterford, and Galway. The range abroad extends to Amurland and Japan. BRIGHT WAVE (_Acidalia_ (_Sterrha_) _ochrata_). At one time this ochreous brown species (Plate 50, Fig. 3) was an inhabitant of the Essex coast, and was found commonly at Southend among other places. Deal and other parts of the Kentish coast are more frequently mentioned in connection with later records of the species. In the present day it is far less plentiful at Deal than formerly, but it is still to be found there. Specimens have been taken in the Isle of Wight, and one has been noted from Suffolk (Aldeburgh).
