lines on the outside, and sometimes connected ; the second projects furthest towards the hind 

 margin in the middle ; nearer the base are one or two slender brown lines ; hind-wings dark 

 grey. Expands from | to \\ inches. It is found on moors in Northern and Alpine Europe, 

 and in Siberia and Labrador, in July ; the northern specimens are paler ashy, and more 

 unicolorous. The larva is yellowish, with fine dark lines on the back, and a yellowish-white 

 stripe on the sides. It feeds on the flowers of Vaccinium oxyococcus in June. 



GENUS VIII.— CHESIAS (TR.). 



Fore-wings without markings, or with transverse or longitudinal streaks ; otherwise as in 

 Anaitis. The larvae are slender, and undergo their transformations on or in the ground. 



*i. C. S/'artiata (Vuessly). — Fore-wings grey, brown on the hind margin, and with a light 

 streak, white and broader behind, which runs below the costa from the base to the tip, and 

 two large spots, surrounded with rusty-brown, on the inner margin and in the middle. Expands 

 from 1 1 to li inches. Inhabits South-Central and Western Europe in September and 

 October. The larva is dark green, with a darker line on the back, bordered with light, and 

 whiter subdorsal and lateral lines. It feeds on broom in May and June. The moth and larva 

 are figured at PI. 50, Fig. 12, a, b. 



*2. C. Oblata (Fabr.), Obliquaria (W. V.). — Fore-wings pale grey, with a band varied with 

 rusty-brown and finely bordered with black before the middle, and a rusty-brown band beyond, 

 blackish towards the base, and bordered with black and white dots towards the hind margin ; 

 and from the latter band runs a rusty-brown dash to the tip, below which runs the whitish 

 and nearly straight subterminal line. Expands about \\ inches. Inhabits Central and Southern 

 Europe in April, May, and August. The larva is green, with a light yellow stripe on the 

 sides. It feeds on broom and Genista in July and August. 



3. C. Griseata (W. V.). — Wings whitish-grey, darkened with dull grey dusting (or unicolorous 

 yellowish-grey, in the variety Infuscata, Eversm.), the fore-wings with a dark shade which divides 

 the tip, and is often continued, though less distinctly, to the hinder angle. Size of Oblata. 

 Inhabits Southern and Central Europe and Western Asia in May. The larva is green or 

 reddish, with a darker line on the back, and a dark line on the sides, bordered with light above. 

 It feeds on Sisymbrium Sophia in June and July. (C Castiliaria, Staud., from Spain, has mouse- 

 coloured fore-wings, shading into olive, with a broad sharply-defined yellowish-grey band towards 

 the hind margin ; hind-wings light grey, with a very suffused light transverse band beyond the 

 middle. Size of a small Griseata.) 



4. C. Asinata (Freyer). — Very like Griseata, fore-wings with indistinct straight oblique 

 denticulated lines, the outer shade better defined, and marked with a white submarginal line, with 

 rounded indentations, and the fringes dotted with grey. Inhabits South Russia. {C. Dnplicata, 

 Hiibn., from South Russia and Armenia, of which Asinata is perhaps a variety, is whitish, the 

 fore-wings with a slight bluish shade, and with two oblique and nearly straight blackish lines, 

 the first line bordered with white, and placed on a slight fawn-coloured shade ; and an oblique 

 black dash at the tip. C. Bosporaria, Herr.-Schiiff., from South Russia, Turkey and Armenia, is 

 dusted with pale ashy, the fore-wings with three oblique darker stripes, of which the first is 

 waved and very narrow ; and the hind-wings white.) 



*5. C. Farinata {Huhn), Nivearia (W. V.). — Wings white, without markings, the fore-wings 

 slightly shading into grey. Expands about l\ inches. Inhabits Central Europe and Western 

 Asia from May to July, but scarce and local. The moth is figured at PL 50, Fig. 13.
