The fore wings have an olive-brown basal patch and central band, both are edged with white, wavy lines, and the band is contracted below the middle. (Plate 65, Fig. 9), and often broken at this point (Fig. 10); the inner marginal portion sometimes very small; the space between the basal patch and central band is pale brown, and so also is the outer marginal area; but there are dark clouds and white marks beyond the {170} white wavy submarginal line. Variable in tint and in marking, the variety generally known as _albocrenata_, Curtis (Plate 65, Fig. 8), is perhaps most frequent in Perthshire and Sutherland. Two other examples of the Scottish form, which Staudinger has named _effusaria_, are depicted on Plate 61, Figs. 8, 9. The caterpillar is green, inclining to yellowish; three stripes on the back, the central one reddish brown and broad, but only distinct at each end, the other paler green; spiracles, white, placed in a reddish-brown stripe, which is sometimes broken up. It feeds on sloe, birch, oak, and the foliage of other trees, and may be found from July to September, and even later. The moth is out in May and June, and is to be beaten from hedges, or may be found at rest on tree-trunks, palings, etc. Generally distributed, but not extending to the Scottish Isles. Abroad, the range spreads to Amurland and Japan. COMMON MARBLED CARPET (_Cidaria truncata_). Six examples of this very variable species are shown on Plate 66, and these have been selected to illustrate the more important forms. There are a number of modifications of each of the forms, and several of these have been named. Fig. 1 of our plate represents the typical form, and this is Haworth's _centumnotata_ (Common Marbled Carpet); Fig. 2 is ab. _commanotata_ of Haworth (Yellow Marbled Carpet); Fig. 3 is ab. _perfuscata_, Haworth (The Brown Marbled Carpet), and Fig. 4 is a modification of the same form. A specimen from Arran is shown in Fig. 5; this example agrees fairly well with that figured in Wood's _Index_ as _concinnata_ from Arran. In his description of the form, Stephens does not mention fulvous bands in his type. Fig. 6 shows a specimen from Stornoway, Isle of Lewis, which appears to be a modification of the typical form of _truncata_, but it has some of the character of _concinnata_. The latter, it may be mentioned, is considered by Mr. L. B. Prout to be a distinct species, and as the genitalia have been found, on examination by Mr. Pierce, to differ from these organs in _truncata_ and _immanata_, there seems to be reason to accept it as such.
