Acid ALIA. 341 



Inhabits Southern and Central Europe and Siberia in July and August. The larva is slender, 

 with transverse folds, and sharp angles at the sides ; it is reddish ashy grey, with a white line on 

 the back, bordered with black. It feeds on lettuce and Rumex. {A. Lnteolaria, Const., is of a 

 smoky ochre-yellow, marked as in Trilincana, but the lines on the upper side are brown, waved, 

 and rather indistinct, and there are sometimes traces of a much waved subterminal shade. It 

 inhabits Spain and the Pyrenees, flying in dry, stony mountain meadows in July.) 



C. — Antenim of the male ciliated, nervures 6 and 7 0/ the hind-wings stalked, hind tibice of tJie 

 males witliout spurs, and those of the females with terminal spurs, and occasionally with middle 

 spurs also; in the males the hind-legs are often rudimentary ; the tibice are sometimes broadly 

 compressed, and furnished with a tuft of hair at tlie base, and frequently expanded into a sheath 

 covering the short foot. 



17. A. Flaveolaria (Hiibn.). — Wings bright ochre-yellow, very slightly and finely dusted with 

 black, somewhat more thickly under the costa ; the fore-wings with three and the hind-wings 

 with two dark transverse lines, which are often very indistinct ; and another very slight waved 

 line before the hind margin ; fringes black. There is a black central stripe on all the wings 

 below. Expands about two-thirds of an inch. It inhabits Saxony and the Alps in July. 



*i8. A. Perochraria (Rossi.). — Wings dull ochreous-yellow, with the subterminal line shaded 

 with brownish on both sides, and brown unspotted fringes ; the fore-wings with three and the 

 hind-wings with two somewhat waved ochre -yellow transverse lines, and the hind-wings sometimes 

 with a small central dot. Expands about three-quarters of an inch. Inhabits the greater part of 

 Europe and Northern Asia in July and August. The larva is moderately slender, and is grey, 

 with three rows of longitudinal streaks, pointed in front. {A. Exilaria, Gu^n., from South France, 

 is smaller, and of a fulvous clay-colour. The fore-wings have three brick-red waved parallel lines 

 on the disc, the last followed by an irregular blackish subterminal band. The hind-wings are 

 marked with two indistinct lines, and those on the fore-wings are also indistinct in the female, 

 and the subterminal band is absent.) 



19. A. Pallidata (W. V.). — Wings pale ochre-yellow in the male, and white in the female, 

 finely and thinly dusted with black, with no central spots ; the fore-wings with three and the 

 hind-wings with two dull brownish-yellow transverse lines, and with the subterminal line bordered 

 with brownish ; the marginal line and fringes are unmarked. Expands about three-quarters 

 of an inch.- Inhabits the greater part of Europe, and the Altai, in May and June. 



*20. A. Subsericeata (Haw.). — Very like the female oi A. Pallidata; white, very finely dusted 

 with black ; the transverse lines narrower and better defined ; olive-grey, the second particularly 

 fine and somewhat zigzag ; the hind margin unmarked, except that there are sometimes a few 

 very small black dots at the root of the fringes ; the under side is also white and less dusted, and 

 the costa of the fore-wings is yellowish, especially beneath. Size of Pallidata. Inhabits Southern 

 and Western Europe in June. The larva is clay-coloured, with a paler line on the back, and a 

 yellowish one on the sides. It feeds on grass, &c., till April. 



*2\. A. Holosericeata (Dup.). — Resembles Scriceata, but shining straw-colour in both sexes, 

 only dusted with darker on the costa of the fore-wings ; the transverse lines are narrower and 

 better defined than in Pallidata, olive-brown, and rather waved ; and the subterminal line is com- 

 posed of light curves. Expands about three-quarters of an inch. Local in Central and Southern 

 Europe, and Western Asia, in July. The larva is short and broad, dark reddish brown in front, 

 and of a more yellowish white behind. There is a dark double line on the back, and clubbed hairs 

 on the sides. {A. Prceustaria, Mann, from Croatia and Dalmatia, differs from Holosericeata in the 

 more pointed fore-wings, and the three transverse lines are more curved towards the base at
