Acid ALIA. 349 



and the space between them is always filled up with reddish or brown, but when the 4th 

 line is absent, the 3rd is but slightly clouded with brown on the outside. There are no central 

 dots ; the fringes are uniform yellow, edged with a narrow black line. Expands from two-thirds 

 to over three-quarters of an inch. Inhabits South France and Spain. {A. Iimstata, Herr.-Schaff., 

 from Austria, is reddish straw-colour, with three darker dentated lines, and black central and 

 marginal dots, the fringes dusted with black. A. Acccssaria, Herr.-Schtiff., probably from 

 South Europe, resembles Incanata, except in structure ; the wings are redder, with round 

 sufiused dots between the terminal and subterminal lines.) 



*56. A. Emargiiiata (Linn.). — Differs from all the preceding species in having a projection 

 in the middle of the hind margin of each wing, above which it is deeply excavated, and behind 

 more slightly. The wings are pale ochreous or rusty-brown, with the central dots placed on 

 a broad brownish but often indistinct central shade ; there is a slender brown marginal line, 

 and the fringes are chequered with brown. There are two reddish-brown transverse lines 

 on the fore-wings, and one on the hind-wings. Expands from three-quarters of an inch to an 

 inch. Common throughout Europe and Northern Asia from June to August. The larva is 

 ochre-yellow, with a brown line on the back. It feeds on low plants till June. The moth is 

 figured at PI. 47, Fig. 9. 



D. — Antenncz of the male ciliated, nervnres 6 and 7 of the liind-ivings separated, the hind 

 tibice without spurs in the male, but with two pairs of spurs in the female ; occasionally both 

 sexes have terminal spurs, or the female has middle spurs also ; the hind margin is waved, 

 or entire, and the hind-wings are sometimes excavated above the middle. 



57. A. Immorata (Linn.). — Wings white, everywhere finely and evenly dusted with black; 

 the marginal area yellowish-brown, with a slender white zigzag subterminal line ; fore-wings- 

 with three broad yellowish-brown transverse lines, and the hind-wings with two, nearly 

 covering the light ground-colour ; central dots absent ; the hind margin scarcely waved, and 

 bounded by a black line, the fringes whitish, spotted with dusky, and divided by a dark line. 

 Expands from i to \\ inches. Common in many parts of Europe and Northern and Western 

 Asia in June and July. The larva is brownish-grey, with several dark longitudinal lines on 

 the back. It feeds on low plants till May. 



58. A. Tessellaria (Boisd.). — Allied to Lnmorata, but the hind margin of the wings distinctly 

 dentated, especially that of the hind- wings, which is excavated above the middle. The 

 surface is only dusted with black at the base, on the transverse lines, and in the marginal 

 area, and is elsewhere pure white ; the nervures are dusky, the two outer transverse lines 

 more sharply defined, and distinctly dentated ; the subterminal line is broad, and divided 

 into spots by the nervures ; and the fringes are not divided by a dark line, but there is a 

 central black spot on the hind-wings. Expands about \\ inches. A rather scarce species, 

 found in the south and east of Central Europe in June and July. It frequents dry rocky 

 places. 



*S9. A. Rubiginata (Hufn.), Rubricata (W. V.). — Wings greyish-brown, more or less varied 

 with purplish-red, with the subterminal line a little paler, and slightly curved ; the fore-wings with 

 three dark transverse lines which are not dentated ; and the hind-wings with two. Expands 

 nearly i inch. Common in Europe, and in Northern and Western Asia, from June to 

 August. The larva is greenish, with an indistinct brown line on the back. It feeds on 

 thyme till June. 



60. A. Turbidaria (Herr.-Schaff.). — Size and shape of Rubiginata ; ochreous-grey, slightly 

 dusted with black, with all the markings blackish, and common, except the inner line, which
