Somewhat similar to the last, but the general colour of the fore wings is paler, inclining to whitish, and the basal patch and central band are pale green tinged with greyish; there is no rosy suffusion, but the wavy sub-marginal line is distinctly white. The hind wings are greyish white, with black discal dot, and dark-grey curved lines. (Plate 68, Figs. 5, 6.) The caterpillar is pale green, inclining to yellowish, especially between the rings, and with a more or less distinct dark-green line along the middle of the back; the points on the last ring are pinkish brown, and there is a line of the same colour along the centre of the under surface of the body. It feeds on alder, birch, oak, sallow, etc., and may be beaten out from June to August. The moth is out in September and October, when it may be obtained at ivy-bloom, and in the following spring, after hibernation, it visits sallow catkins. The range in the British Isles agrees pretty closely with that of the last species, but in Scotland it extends to the Hebrides and to the Orkneys. [Illustration] 2 Pl. 68. 1-4.

BARRED YELLOW: _caterpillar_. {175} NOTE.--According to Prout, _sagittata_ is not a _Cidaria_, as its larva is of a very different form; and _siterata_ and _miata_ are referred to _Chloroclysta_, Hubner. GREY PINE CARPET (_Thera variata_). In its typical form, the fore wings of this species are greyish, and from this the colour ranges through various tints of greyish brown to smoky brown or blackish; sometimes these wings are shades of ochreous brown. The usual markings are a basal patch, more or less clearly defined, and a central band, and these may be either brown or blackish; the band varies in width, is not infrequently narrowed or contracted below the middle, occasionally broken at this point, and more rarely only represented by a small angular spot near the front margin. Four examples are shown on Plate 70, and of these 1 and 2 represent our ordinary form _obeliscata_, Hubner (Shaded Broad Bar, of Newman). Fig. 6 is a blackish banded specimen of the _obeliscata_ form, and Fig. 3 is the almost entirely blackish form _obliterata_, White (_scotica_, Staud.), which is not uncommon in the Paisley district, and other parts of Scotland, and also occurs in a modified form in some pine-woods in the South of England. The long caterpillar (Plate 71, Fig. 1), which feeds on the needles of Scots pine in April and May, also in July, and sometimes in September, is bright green, with three whitish lines along the back, the central one broad, and a yellowish line low down along the sides; the green roundish head is lined with white.
