r40 European Butterflies and Moths. 



reddish fascia, and the stigmata are bordered with white on both sides. The female is 

 greyish-white, more transparent, and less distinctly marked. Expands ij inches. It is found 

 in Russia and Gallicia in April and May, and the larva is supposed to feed on birch. 



GENUS XIII.— MICRODONTA (DUP.). 



The thorax is covered with loose woolly hair ; the fore-wings are rounded, with the tip 

 rectangular, and the hind-wings are also rounded. The larvte have sixteen legs. They are 

 smooth, without protuberances, and change to pupse in a loose cocoon beneath the ground. 

 The only species, * M. Bicolora (VV. V.), is white, and the fore-wings have a row of orange 

 spots before the middle, bordered in front with black. The two lowest are connected, and 

 produced behind into a longitudinal streak. Expands nearly \\ inches. Widely distributed 

 in Northern and North-Central Europe from May to July, but not very common. Varieties 

 named Albida (Boisd.) and Unicolora (Men.) are sometimes found in Russia, in which the 

 fore-wings are almost or wholly white. The larva is grass-green, whitish above, with four 

 dark lines on the back, and a yellow stripe on the sides. It lives on birch in July and 

 August. The moth is figured at PI. 31, Fig. 5. 



GENUS XIV.— GLUI'HISIA (STEni.). 



The thorax is densely hairy ; the fore-wings are broad, with long hind and inner margins, 

 the former waved ; and the hind-wings are short. The larvae have si.xteen legs, and are 

 naked, without protuberances. They live and undergo their transformations between leaves 

 which they have spun together. The only European species, * G. Crcnata (Esp.), has dark 

 grey fore-wings, with two black transverse lines bordered with paler before and behind the 

 middle, a similar line, dentated in the middle, before the hind margin, and a pale grey central 

 lunule. The hind-wings are grey, with the hind margin broadly blackish. Expands about 

 \\ inches. It appears to be distributed throughout Central Europe, but is a great rarity 

 everywhere. It is double-brooded, appearing in April, and again in July. The larva is 

 yellowish-green, with a whitish line on the back, bordered with yellow, and spotted or inter- 

 sected with red, and a )'cllowish stripe on the sides. It feeds on poplar in June and autumn. 



GENU.S XV. — LEIOCAMPA (STEPH.). 



In this and the following genera, the thorax is densely woolly, slightly crested behind ; 

 the hind margin of the fore-wings is slightly undulating, and the inner margin has only a 

 sli<Tht tooth of scales. The eyes are naked, and the larva; are sixteen-legged and naked 

 (except in Notodontd) ; the latter live on trees in summer, and form their cocoons in the 

 ground ; and the moths appear in spring. In Leiocampa the fore-wings are rather long, with 

 an oblique hind margin, the tips truncated, and a slight tooth on the inner margin. They 

 are brown and white, with no transverse markings. The larva? are smooth, with a slight 

 pyramidal elevation on the 12th segment. 



* \. L. Dict(Ea (Linn.), {SivalUnv Proinincnt). — I'"ore-wings pale brown, broad!}- whitish 

 beneath the costa, with two dark brown longitudinal spots before the tips, and a dark brown 

 longitudinal streak above the inner margin, intersected by whitish dashes, and behind by the 

 whitish nervures ; the hind-wings are whitish, with a dark grey spot at the anal angle.
