BRITISH AND EUROPEAN BUTTERFLIES AND MOTHS. 



composed of three or four similar lines, the 

 anterior being spotted with dark brown on 

 the costa and in the middle and the posterior 

 only in front; the latter has an angular pro- 

 jection in cell 3 and on nervure 6. Midwa}^ 

 between the bands there is a dark oblique 

 streak. There is a rusty brown line dividing 

 the apex, a distinct submarginal line, bordered 

 on the inner side by a number of dark trans- 

 verse lines, and a dark marginal line expanded 

 into spots on the nervures. The fringes have 

 a single band and are finely white on the 

 nervures. Hind wings light grey, darker 

 towards the hind margin with a faint central 

 spot, but no other markings. The marginal 

 hne and fringes are as on the fore wings. 

 Head and thorax bluish grey with a brown 

 hind margin to the collar; abdomen light grey. 

 It is common in meadows and woods through- 

 out Central Europe from June to August. The 

 larva is coppery-brown with a dark dorsal and 

 narrow pale j-ellow lateral line. It feeds on 

 Hypericum perforatum. Pupa light brown, elong- 

 ated, with a long proboscis sheath. It is placed 

 under dried leaves on the ground. 



A. praeformata, Hubn. resembles plagiata 

 but is larger. On each side of the central 

 area of the fore wings, in their costal half, 

 is a dark brown band, bounded by two dark 

 lines, both of which or only the posterior being 

 intersected by a similar line. Hind wings 

 lighter than in plagiata. It is found in moun- 

 tainous districts in Central Europe in July. 



A. imbutata, Hubn. The Manchester 

 Treble-bar. Fore wings bluish ashy grey, 

 dusted with brown, especially at the base, but 

 sharply defined near the anterior transverse 

 band. There are two rusty brown transverse 

 bands, the posterior of which forms two obtuse 

 angles towards the hind margin ; corresponding 

 with this is an indistinct submarginal line 

 which commences below the apex and is 

 suffused with reddish on its anterior half, as 

 far as the posterior transverse line. Above 

 this is a fine bluish grey streak, with a white 

 end in the outermost tip of the wings, and 

 there is a small dark brown spot on the costa. 

 The black marginal line is somewhat thickened 

 between the nervures. The fringes are finely 

 intersected with white on the nervures and 

 banded through the middle. Hind wings 



light brownish with a scarcely perceptible paler 

 transverse line, a dark marginal line and fringes 

 which are less sharply defined than on the 

 fore wings. It is found in mountainous districts 

 in Central and Northern Europe. The larva 

 is reddish yellow with three violet stripes on 

 the back and a yellow one on the sides. It 

 feeds on cranberry. 



Genus Chesias, Treit. 



Middle-sized silky scaled moths, with rather 

 long wings and somewhat angular tips. Fore 

 wings with a slightly curved costa and a broad 

 projecting rounded hinder angle. Hind wings 

 without markings and extending far beyond 

 the hinder angle of the fore wings. Palpi 

 coarsely scaled, pendulous, projecting bej'ond 

 the head. Proboscis spiral. Antennse setiform, 

 slightly ciliated in the males. Front femora 

 crooked and thickened, the corresponding tibiae 

 with terminal claws. Abdomen thickened at 

 the extremity in the males, and shortly scaled. 

 Neuration as in the last genus, but less strongly 

 marked. They sit with the wings covering 

 the body and are easily disturbed. 



C. spartiata, Fuessl. The Streak. Fore 

 wings bluish grey, with the nervures black 

 dotted with white in the position of the trans- 

 verse lines. There are three white longitudinal 

 spots in the central area, the first of which 

 extends as a white streak, bordered in front 

 with tawny, to the apex of the wings, whilst 

 the two others are tawny and are more or 

 less complete oval figures. The almost straight 

 submarginal line, which forms the dark shading 

 of the white streak, is edged with tawny on 

 the outer side. The thick black marginal line 

 is finely interrupted with wliite on the nervures. 

 The fringes are brown on their basal half, 

 but much lighter at the apex. Hind wings 

 brownish grey somewhat darker towards the 

 hind margins, with pale fringes in the male, 

 indistinct in the middle and banded with 

 darker, and with a similarly faint dark mar- 

 ginal line. Body greyish-yellow, thorax whitish 

 varied with brownish. It is common in the 

 South and West of Central Europe, fron^ 

 August to October. The larva is slender, 

 constricted at the incisions, and somewhat 

 flattened, with angular sides. It is green with 

 three whitish longitudinal lines and darker
