The species is often common in the south and east of England, and along the western side, including Wales, up to Cheshire and Lancashire, but it becomes local in Worcestershire and northwards. There are few records of it from Yorkshire, and its occurrence in Durham, Northumberland, and Scotland is doubtful. In Ireland it appears to be widely distributed, but scarce. The range abroad extends to Amurland, Corea, and Japan. [_Thalera fimbrialis_. A specimen of this Central European species (identified by the late Mr. C. G. Barrett) was taken on August 7, 1902, by Mr. C. Capper, from a blade of grass growing on a slope under Beachy Head, Sussex. The species is somewhat similar in appearance to _H. strigata_, but is larger; the hind wings are notched above the angle on the outer margin; the fringes of all the wings are chequered with red, and the antennae of the male are bipectinated.] {109} ACIDALIINAE. PURPLE-BORDERED GOLD (_Hyria muricata_). Two forms of this pretty little species (known also as _auroraria_) are shown on Plate 45. Fig. 1 represents the more usual form, but between this and the almost entirely purple variety (Fig. 4), which occurs chiefly in the north, there are various modifications. Then again, especially in the south of England, there is a tendency to become entirely yellow, the purple, inclining to crimson in such specimens, being confined to the front margin and cross lines on the fore wings, and a narrow band on the outer margin of all the wings. The caterpillar is pale brownish, inclining to ochreous at each end, marked with irregular blackish lines on the back, and dots and streaks on the sides. Its natural food plant seems to be unknown, but when reared from the egg the caterpillar will eat knotgrass, and sometimes a few will feed up and attain the moth state the same year. August to May. The moth occurs in late June and in July, and frequents fens, boggy heaths, and mosses. Although odd specimens may, occasionally, be flushed during the day, the collector will need to be up early in the morning if he would see this species on the wing, as it seems to fly most freely about sunrise. The New Forest in Hampshire is a noted district for it, as also are Ranworth, Horning, etc., in Norfolk, and Witherslack in Westmoreland. In Ireland, it is found in counties Galway, Kerry, and Mayo. Abroad, the range extends to Amurland, China, Corea, and Japan. WEAVER'S WAVE (_Acidalia_ (_Ptychopoda_) _contiguaria_). The earliest known British specimen of this species (Plate 45, Figs. 2 and 5) was taken in North Wales by Weaver, in 1855, {110} and was figured and described in _The Entomologist's Annual_ for 1856 as _Dosithea eburnata_, Wocke. About seven years later Greening captured a female specimen, and he subsequently reared the insect, when it became known as "Greening's Pug." Still later, about 1875, the English name was changed to "Capper's Acidalia."
