The fore wings are rather rounded; grey, more or less tinged with brownish, and with ochreous or reddish brown along the front edge; the latter with dusky clouds upon it; the cross lines are dark grey brown and fairly distinct, and the discal spot is black (Plate 98, Fig. 5). A large grey form from Moray, in Scotland, has been named _cinerae_, Gregson. Caterpillar, rather stumpy, and dingy yellowish green in colour, the sides and middle of the back rosy; a series of dusky spots, edged by black lines or short streaks, along the back; and a row of pinkish oblique stripes on the sides. It feeds, in the spring, in sallow catkins, and the moths may often be bred in numbers, in June and July, from those catkins which fall most readily from the bushes when we go "a sallowing." Moths frequently rest on the stems, and where there is a clump of well-grown sallows, a good series may be obtained. The species is partial to fens and marshy places, and is found in such situations over the greater part of the British Isles. {246} MAPLE PUG (_Eupithecia inturbata_). The fore wings are greyish brown, with many darker cross lines; the outer margin is darker and traversed by a pale line; discal dot, dark grey and not very distinct (Plate 98, Fig. 6). This species was long known as _subciliata_, Guenee, but is now referred to _inturbata_, Hubner. In May and June the caterpillars may be beaten from maple, which is apparently the only food plant, and of which they have a decided preference for the flowers. When full grown the larva is yellowish green with a purplish stripe along the back, and whitish lines along the sides. The moth may be jarred from the branches of the maple in July and August; it is occasionally seen resting on fences, etc. It seems to be found in England and Wales, in most places where there is a mature growth of maple. THE ANGLE-BARRED PUG (_Eupithecia innotata_). The greyish-brown fore wings of this species (Plate 98, Fig. 7) are crossed by darker oblique lines, which are angled on the front margin; the submarginal line is white and irregular, especially at each end. Caterpillar, ochreous grey, inclining to pinkish, marked on the back with white-edged, purplish- or reddish-brown blotches, and on the sides with reddish or purple spots; a whitish line low down along the sides. It feeds on the flowers of wormwood and mugwort (_Artemisia_), from August to October. The moth, which is uncommon and very local in England, is out in July. It occurs in Devonshire (Exeter district), Kent (Wye), Essex (Shoeburyness), Lincolnshire (Skegness, etc.), Worcestershire (Malvern), Lancashire and Cheshire (coast sand-hills, Macclesfield, etc.), and Durham (Hartlepool). {247} ASH PUG (_Eupithecia fraxinata_). Very similar to the last mentioned, but smaller, and the markings are less distinct (Plate 98, Fig. 8).
