The caterpillar is brown, inclining to blackish or purplish, the raised spots are black, and occasionally the sides are freckled with orange (Plate 126, Fig. 2, from a coloured drawing by Mr. A. Sich). It feeds in May and early June on oak, and will also eat hawthorn, birch, and elm. The moth, which is out in February and March, appears to be local, but has a wide distribution through England from Durham to Hampshire, and even Devonshire. It has also been recorded from Denbighshire, North Wales. A well-known locality is Richmond Park, in Surrey, and here it is found resting on oak trunks or on the grass stems, etc., under or around the trees. The male is attracted by light. RANNOCH BRINDLED BEAUTY (_Nyssia lapponaria_). The sexes of this species are shown on Plate 134, where Fig. 3 represents the male, and Fig. 5 the female. It was not known to occur in the British Isles until 1871, when a male specimen was captured in Perthshire, on April 20 of that year. Mr. William M. Christy, in 1895, bred some moths from larvae obtained in the Highlands of Scotland, and he sent eggs to Mr. F. W. Frohawk, who worked out the life history, and described and figured all the stages from egg to perfect insect (_Entom._ xxviii. 237). In July, 1900 and 1901, Mr. E. A. Cockayne found {298} caterpillars, in Perthshire (Rannoch district), on ling, heath, and bog-myrtle; and in June, 1904, he published (_Entom._ xxxvii. 149) some interesting observations on the habits of the species in its native haunts. The greenish yellow eggs are laid in batches of 10 to 150 in the dry corollas of the cross-leaved heath, and less frequently between the stem and sheath of reeds, or in cracks in dead bracken stems, etc. The caterpillar (Plate 126, Fig. 3) is pale drab, inclining to a yellowish tint; irregular yellow stripes along the back and sides, and lines of blackish streaks between the stripes. It will eat birch, sallow, and hawthorn, in captivity; but in the open it feeds on heather and bog-myrtle: May-July. The chrysalis is reddish brown, rather paler on the wing covers (figured on Plate 126 from a photo, twice natural size, by Mr. H. Main). The moth is out in April and May, and sits on the twigs of heather and the stems of bog-myrtle. It has only been recorded from Perthshire, and is there very local, frequenting damp places near streams. Mr. A. W. Mera has obtained hybrids from a crossing of this species with _N. zonaria_.
