342 European Butterflies and Moths. 



the costa ; towards the hind margins of all the wings the ground-colour shades into lead-colour, 

 and the subterniinal line is much more indistinct. A. Nitidata, Herr.-Schaff., from Hungary, 

 is larger than Pallidata ; straw-coloured and shining, the lines grey; the second line forms on 

 nervure 3, and the third forms on ncrvures 3, 4, and 6, sharp angles outwards ; the first and 

 third arc a little more distinct than the others, and the central shade, and the dark edging 

 on each side of the light subterminal line, are very broad.) 



*22. A. Circellaia (Guen.). — Wings rounded, silky, of a rather smoky white, but with hardly 

 any black atoms ; the central and marginal black dots very distinct ; the lines are also very 

 distinct, especially the elbowed line, which is waved and denticulated. The central shade is 

 close to this, well marked, and nearly straight on the fore-wings. It passes over the central dot on 

 the fore-wings, and below it on the hind-wings. There are two smoky-brown subterminal shades, 

 quite disconnected from the elbowed line or the hind margin ; and the under side of the wings is 

 uniform smoky-brown. Expands three-quarters of an inch. It occurs near Manchester in June. 

 {A. Diffliiata, Herr.-Schaff., from Hungary, is one-third larger than Bisetata, with which Herrich- 

 Schaffer compares it, though Staudinger places it here. Lines i and 2 are very indistinct, and 

 the subterminal line is not indented towards the base in cell 4, but the dark space in cell 3 is 

 sharply bounded by the second transverse line, without its encroaching upon it, as is generally 

 the case in Bisetata. On the under side the dark band on the inner side of the subterminal line is 

 much narrower.) 



23. A. Diliitaria (Hubn.). — Wings shining straw-colour, with a black central dot, the trans- 

 verse and subterminal lines as in Holosericcata, and the costa of the fore-wings dusted with brown 

 as far as the middle, and strongly arched before the tips ; the hind margin marked with black dots 

 or streaks between the nervures, and the fringes often with a few black dots on the ends of the 

 nervures. Expands about three-quarters of an inch. Inhabits Europe, except the west, and 

 the Amoor, in June and July. The larva is dark ochreous, broad, narrower at each end, and 

 transversely wrinkled ; the lOth segment is pale yellow ; it feeds on moss. 



*24. A. Hiuniliata (Hufn.), Osscata (W. V.). — Wings yellowish, with fine black central dots, 

 a dark shaded subterminal line, a fine darker marginal line, and unspotted fringes ; the fore-wings 

 reddish-purple along the almost straight costa, with three rather waved olive-grey transverse lines, 

 and the hind-wings with two. Expands about three-quarters of an inch. Inhabits Europe and 

 North Africa from June to August. The larva is transversely wrinkled, attenuated in front, and 

 with dark spots on the back. The moth is figured at PI. 47, Fig. 6. {A. Robiginata, Stand., from 

 Castile, is deep ochre-yellow, the fore-wings with three stripes, and the hind-wings with two, the 

 fringes preceded by blackish dashes almost forming a line, and marked with a row of -black dots 

 at the base ; the under side is very distinctly marked, except that the first line on the fore-wing is 

 absent.) 



25. A. Obsoletaria (Ramb.). — Wings pale reddish-grey, not dusted with black, with a fine 

 black central dot, and a suffused subterminal line ; the fore-wings with three brownish lines, curved 

 on the costa, and the hind-wings with two, the hind margin unmarked, but the base of the 

 fringes marked with fine, and mostly indistinct, black dots. Expands about two-thirds of an 

 inch. Inhabits South Europe and some parts of Eastern Germany. 



26. A. Helianthemata (Mill.). — Wings of a fine uniform ochreous brick-red, including the 

 rather long fringes, and dusted with well-defined black atoms. The central area, bounded by a 

 slender black streak, is marked on the first half by a broad black band, formed of accumulated 

 black dots, which is rather narrower on the hind-wings. The central black dots are visible on the 

 hind-w ings, but covered by the black band on the fore-wings. The fringes are marked with rather
