Excerpt from Illustrations of British Entomology, Vol. 4: Or, a Synopsis of Indigenous Insects, Containing Their Generic and Specific Distinctions, With an Account of Their Metamorphoses, Times of Appearance, Localities, Food, and Economy, as Far as Practicable, Embellished With Coloured Figures of the Rarer And Anterior wings ochry-griseous, thickly hut irregularly marked with minute transverse obscure streaks, with two oblique dusky lines, having a dark spot between them near the costa, the basal line nearly straight, the posterior one more or less waved towards the costa, the wing from the latter to the hinder margin is rather darker than the base, and has in general a more or less distinct pale waved streak, the margin itself is brown, with darker cilia, intermixed with white: posterior wings paler, generally with an obscure streak towards the middle on the inner edge, and a faint central dusky dot, the hinder margin darker, with fuscous cilia. The oblique strigæ on the anterior wings are sometimes nearly approximating, and at others widely apart. Caterpillar brown with darker spots: it feeds on the birch during the autumn, changes to a pale ashy-brown pupa, and appears in the perfect state in the following May. Not very uncommon in the woods in the vicinity of London, especially at Coombe and Darenth, where birch is abundant, it also occurs in other parts of the country. "Durdar." - T. C. Heysham Esq. "York." - W. C. Hewitson, Esq. "Meldon Park." - G. Wailes, Esq. Sp. 2. cultraria. Alis anticis ochraceis, strigis duabus parallellis fusco-ferrugineis, punctoque interjecto fusco: posticis albidis, immaculatis. (Exp. Alar. 1 unc. 2 - 5 lin.) Pl. cultraria. Leach. - Pl. cultraria. Steph. Catal. pt. ii. p.156. No. 6750. Anterior wings pale ochre, sometimes with a griseous cast, with two rather distinct strong parallel rusty-brown oblique lines, having a brown spot between them near the costa, hinder margin umber-brown, fringe brown and white intermixed: posterior wings whitish, spotless. This species has occurred occasionally within the metropolitan district, but it appears to be in plenty at Monk's Wood, Hunts, which induces me to consider it distinct: the hinder margin of the anterior wings appears to be less deeply notched than in Pl. Lacertula, and the general habit of the insect is different. Genus CCXLIV. - Drepana, Laspeyres. Palpi minute, conic, remote, scarcely projecting beyond the scales of the head: maxillæ very short.
