It feeds on bedstraw, in June and July, and a second brood occurs in September. The figure of the brownish, inclining to reddish, chrysalis (Plate 79, Fig. 4), is from a photo by Mr. H. Main, and is twice the natural size. The moth is out in May and June, and, in the South especially, again in August and September. It is generally distributed over the British Islands, but so far has not been noted from the Shetlands. The range abroad extends to Eastern Siberia and Amurland. According to Prout, the earliest name for this species is _alternata_ (Muller). SMALL ARGENT AND SABLE (_Xanthorhoe_ (_Epirrhoe_) _tristata_). On Plate 81 are shown three examples of this variable species. Fig. 10 represents the typical form from N. Devon. Fig. 11 is a black-marked specimen from Yorkshire, and Fig. 12 depicts a smoky-brown marked specimen from Clydesdale, in which the ground colour has a brownish tinge. All these have the central band more or less entire, but this character may be broader or narrower, and is sometimes divided into two parts, and these reduced to very small proportions; the white projections into {199} the outer marginal border of all the wings is not infrequently enlarged, in some cases so much so that the borders are separated into two parts, and also reduced in width. The caterpillar is grey brown, ochreous brown between the rings and on the underside; a dark line along the back, and a dark-edged, pale line on each side; a black dot on each ring at the junction of the dark upper and pale lower areas; head, grey-brown, with blackish freckles. It feeds, in July and August, on bedstraw, preferring the heath kind (_Galium saxatile_), but will eat the large hedge kind (_G. mollugo_). The moth is out in June, or from late May, and in some parts specimens are seen in August. Its haunts are moors and upland heaths, and its British distribution extends from Dartmoor and Exmoor, in Devon, through Western England and Wales to Westmorland. It appears to be very local in Somerset, Gloucester, Hereford, Shropshire, and Cheshire; from Staffordshire and Derbyshire northwards, and through Scotland, it becomes more plentiful; and has been recorded from the Shetlands. In Ireland it is local, but common where it occurs. SHARP-ANGLED CARPET (_Xanthorhoe_ (_Euphyia_) _unangulata_). This species (Plate 82, Figs. 1, 2) may be recognized by the distinctly angled outer edge of the blackish central band, which is thrown into strong relief by the usually broad white stripe following it. Wilkes, who figured the moth in 1742, called it the "White Stripe." By some authors the species is referred to _amniculata_, Hubner. The caterpillar is pale whity brown, with a slightly darker but indistinct line along the centre of the back, and a black spot on the middle rings; a pale line on the sides is edged with dark grey; head, brown, marked with black. It feeds, in July and early August, on chickweed (_Stellaria media_).
