Abroad, the range extends to Amurland and Japan.
Lilac Beauty (Hygrochroa (Pericallia) syringaria).
The sexes of this species are shown on Plate [112], and it will be noted that the male (Fig. 7) is rather smaller and decidedly more brightly coloured than the female (Fig. 8). An older English name is "Richmond Beauty," Wilkes. Figures of the curiously shaped caterpillar and chrysalis will be found on Plate
[115], Figs. 2, 2a. The former is yellowish brown, variegated with reddish and violet; it feeds on honeysuckle, lilac, and privet, and may be beaten or searched for in May and early June, after hibernation. I have found it commonly on privet hedges in the Mill Hill district, Middlesex, but in woods, and especially in the New Forest, it is obtained from honeysuckle. In my experience, the privet-feeding caterpillars always produce larger moths than those reared from caterpillars fed on honeysuckle. The moth emerges in June and July, the former month chiefly in confinement, and from such early moths a second generation may be obtained in the autumn.
Although most frequent in the southern half of England and Wales, the range of the species extends to the northern counties; and single specimens have been recorded from Durham and Northumberland, but the species has not been noted in Scotland.
The distribution abroad extends to Amurland and Japan.
Scalloped Hazel (Gonodontis bidentata).
This species varies in ground colour, from pale whity brown through shades of grey brown, olive brown, ochreous, and dark brown to black; the blackish cross lines of the fore wings are generally edged with white, but the edging is sometimes absent, and occasionally it alone remains distinct; the central space enclosed by the cross lines is often darker than the general colour, and not infrequently it is faintly reddish. Figs. 1 and 2, Plate [114], represent two of the more usual forms of the species. Fig. 3 is the black ab. nigra, Prout, which occurs on the mosses of Lancashire, and in Yorkshire.
The yellowish and brown mottled, purplish caterpillar is figured on Plate [115], where also are shown the eggs (turquoise blue, changing to reddish brown), and the reddish brown chrysalis. The latter, which is twice the natural size, is from a photograph by Mr. H. Main. The caterpillar feeds on the foliage of oak, birch, sallow, hawthorn, sloe, plum, larch, etc.; it grows very slowly, and may be beaten out in most of the months from July to October. The moth is out in May and June, and sometimes earlier. Pretty generally distributed over the British Isles, but not noted in the Orkneys or Shetlands. The range abroad extends to Amurland and Japan.
