128 Europe AX B utter j-lies axd Moths. 



I. G. Bctiilifolia (Fabr.). — Wings reddish-brown, suft'used with grey on the hind margins, and 

 with white fringes spotted with brown ; the fore-wings are marked with three rows of blackish 

 lunules, and are deeply excavated at the hinder angle. Expands from i J to nearly 2 inches. It 

 occurs throughout the greater part of Central Europe and Northern Asia in May, but is scarce in 

 most localities, and absent from Britain and Scandinavia. The larva is grey, with reddish-yellow 

 transverse stripes on the 3rd and 4th segments, and a short tubercle on the last segment but 

 one. The belly is rust-colour, spotted with brown. It lives on oak, birch, &c., in autumn. 



* 2. G. Ilicifolia (Linn.). — Very like the last species, but more suffused with grey; hind-wings 

 almost entirely grey, with a paler band in the middle ; a square greyish-white spot in the middle 

 of the fore-wings. E.xpands from \\ to if inches. It seems to be found throughout Central 

 Europe and Northern Asia in April and May, but is everywhere a scarce and local insect. The 

 larva is rust-coloured, with a black stripe on the back, on which stand white dots; and with reddish- 

 yellow transverse spots on the 3rd and 4th segments ; or else it is grey, and the back white, with 

 a broad black central stripe interrupted by rust-coloured spots dotted with black. It feeds on 

 sallow and bilberry in July and August. 



3. G. Subcrifolia (Dup.). — Pale coffee-brown, with reddish fringes. It is of the size of the 

 last two species, but the hind margins are less dentated, the hind-wings are more oblong, and 

 the transverse lines are nearly obsolete. It is found in South France, Spain, and North Africa in 

 August, but is a very scarce insect. The larva feeds on Q/icirus Siiber in June. 



*4. G. Qnaxifolia (Linn.), {Lappet Moth). — Reddish-brown; the fore-wings with three black 

 lines, more or less dentated ; but the inner margin is not concave. It varies much in depth of 

 colouring ; the var. Aliiifolia (Ochs.) is dark brown, and the van called by the same name by 

 Dahl is pale yellowish-grey, with the markings sharply defined. Expands from 2 to 3 inches. It 

 is found throughout the greater part of Europe and Northern and Western Asia in June and 

 July. The larva is brown or grey, with blue transverse spots on the 3rd and 4th segments, small 

 hairy tubercles on the sides, and a tubercle on the last segment but one. It lives from autumn to 

 iVIay on fruit-trees, sloe, willow, &c., and is often met with in plantations of young trees. The 

 transformations are figured at PI. 28, Fig. i, a — c. 



5. G. Popiilifolia (W. V.). — Resembles the last species, but the wings are longer and paler, 

 and the fore-wings are marked with five rows of dark lunules. A smaller and paler brood of both 

 this species and the last is met with in warm summers. It is found throughout Central Europe 

 (except England) in June, but appears to be scarce everywhere. The larva resembles that of 

 Quercifolia, but the transverse spot on the 4th segment is reddish-yellow, bordered with dark grey. 

 It lives on poplars and willows from autumn to May. 



GENUS II. — LASIOCAMPA (SCHRANK). 



Hind margins of the wings, or at least of the hind-wings, dentated or waved (except in 

 L. Rubi), and shorter than the inner margin ; fore-wings generally with a pale spot in the middle. 

 The cocoon is rather loose. 



I. L. Priuti (Linn.). — Reddish-orange; all the wings dentated; fore-wings with a whitish spot 

 in the middle, and two dark transverse lines, the hinder one dentated, and reaching the costa 

 much before the tip. E.xpands about 2\ inches. Found throughout a great part of Central and 

 Southern Europe (except Britain) in June and July, but is a scarce insect. The larva is bluish- 

 grey, spotted with whitish, with yellowish longitudinal lines, a reddish-yellow transverse spot on the 

 4th segment, and a hairy tubercle on the last segment but one. It lives from autumn to May on 

 forest-trees and fruit-trees. The moth is figured at PI. 28, Fig. 2.
