Most of the British examples of this species have the thorax and fore wings almost pure white, the latter with a central blackish grey band (var. _leuconota_, Ev., Plate 125, Figs. 3[male], 4[female]). The white, however, especially on the outer margin, is sometimes clouded with greyish, and occasionally the ground colour has a greyish tinge, thus approaching var. _obscura_, Staudinger. The caterpillar is ochreous brown, more or less tinged with green, minutely dotted with dark grey, forming indistinct blotches; the stripe along the black spiracles is yellow tinged with green below. Head brownish, glossy. It feeds in July and August on hawk's-beard (_Crepis_). The smaller caterpillars may be found by day resting on the yellow flowers. In confinement they will eat the flowers and seeds of garden lettuce; and Prout mentions dandelion blossoms, and also those of almost any of the Compositæ. The moth is out from June to August, and in the daytime may be seen sitting on fences, tree trunks, rocks and walls. It is pretty generally distributed in the southern portion of England, but becomes scarce northwards. In Scotland it seems to be little known, but Renton records it as common in Roxburghshire, and in 1898 Mr. Kirkaldy kindly gave me three greyish-shaded specimens that he picked up casually at Pitlochry, Perthshire, in July of that year. It has been found in North Wales, but is more frequent in the southern parts of that country. Rather local and usually scarce in Ireland; but has been found in counties Waterford, Dublin, Wicklow, Louth, Antrim, Westmeath, Galway, Cork, and Kerry. The range abroad extends to Siberia and Amurland. THE BORDERED GOTHIC (_Neuria reticulata_). The cross lines and the veins are pale brown, sometimes tinged with pink. These markings give the moth (Plate 126, Figs. 1[male], 2[female]) a netted appearance, which, apart from the different ground colour and clouding, distinguishes it from the Gothic, with which it is sometimes confused. The antennæ, too, of the male are only fringed with minute hairs, whilst those of the male Gothic are broadly pectinated. The caterpillar is greenish or pinkish ochreous, mottled with darker, and with slightly paler lines on the back and sides; head light brown. It will feed in July and August on knot-grass; and soapwort (_Saponaria_), _Silene inflata_, and _Dianthus_, have been mentioned as food plants. The moth is out in June and July. The species occurs in nearly all the counties of England to Yorkshire, but except in Cambridgeshire, and perhaps Oxfordshire, it is not common in any of the southern or eastern counties, although more frequently found in them than northwards. It has not been recorded from Scotland, and seems to be rare in Ireland, as it has only been noted from Co. Dublin and Co. Cork. [Illustration] Pl. 126. 1, 2. BORDERED GOTHIC. 3, 4. DUSKY SALLOW. 5.
