ANAITIS. By L. B. Prout. 175 



grey, unmarked. Underside paler, the costa of the forewing somewhat darkened and with the anterior part of 

 the postmedian line showing through. Transcaspia, Zerafshan and Buchara. The original specimen was caught 

 on 28 April. 



L. notata B.-Haas. Forewing ash-grey, sprinkled with black, and irregularly sliaded with yellowish, notata. 

 especially in the middle: a white subcostal streak, usually widening into a white spot before the apex; a 

 small, pointed white spot distally to the discocellulars; sublerminal line white, straight, not reaching either 

 margin, the veins anteriorly to this line sometimes dotted with black; some specimens also show faint traces 

 of a black, distally yellowish-shaded postmedian stripe; marginal line blackish, interrupted with whitish; fringe 

 whitish, divided by a grey line. Hindwing greyish with faint lighter submarginal line. Forewing beneath 

 grey- white, darker towards the base, a postmedian line indicated at the costa; hindwing more snow-white, 

 markinglesF. Expanse about 26—31 mm. Tunis: Gafsa, Dehibat, Foum-Tatahouine ; Algeria: South of Biskra. 



L. marmorata B.-Haas. A very small, very distinct species, unknown to me in nature. Forewing marmorata. 

 white, with very faint tinge of yellowish; median area enclosed by very sharp, irregularly curved brown-black 

 lines; a brown costal spot near the apex, reaching about to the 1^' radial; the wing is also sprinkled with 

 scattered brown scales, which become more numerous in the distal area and form (judging by the figure) some 

 ill-defined blotches distally to the postmedian line in the posterior half of the wing; fringe irregularly chequered 

 with brown. Hindwing concolorous with forewing, with a diffuse blackish cell-mark; marginal line distinct, 

 brown, widened into a spot at the anal angle. Under surface more uniformly dark-dusted, the markings o^ 

 the upperside weakly reproduced. Gafsa, Tunis. 



L. (?) chaoticaria Alph. I do not know this species, described by Alpheraky as an Anisopteryx, but chaoticaria. 

 suspect it may belong here. The description compares it with Phthorarcha primigena. Aspect similar to that 

 species, colour the same, antennal ciliation much shorter. Size smaller (about 30 mm), wings broader, less 

 elongate, all the markings wanting except the oblique apical mark of the forewing, which is even larger and 

 more sharply defined than mprimigena. Discovered by Grum-Grshimailo 10 April 1890 in the Nan-Chan Mountains. 



19. Genus: Ana'itis Dup. 



Characters of Lithostege, but the forefemur not thickened, foretibia less extremely short, not forming 

 a broadened horny plate at end, the outer claw obsolete, the inner less long and strong than in Lithostege. 

 The face is on the whole more oblique, with a cone of projecting scales, the palpus rather stronger, but these 

 latter distinctions are not constant. 



Anaitis has been divided into two sections, or even two genera (Anattis and Docirava) according to 

 the structure of the costal vein in the cf hindwing; in the first it anastomoses with the subcostal (as in all 

 the ??), while in the latter it is merely connected near the end of the cell, as in Schistostege. Of the species 

 which I have examined, only plagiata, praeformata, postochrea and possibly simpliciata would belong to the 

 former, lythoxylata, mundulata, columhata, hoisduvaliata, ohsitaria, opificata, piidicata, afpnis, aequilineata and 

 fulgurata to the latter, but simpliciata is intermediate, the anastomosis being short and restricted to the distal 

 part of the cell, and even in postochrea it is less pronounced than in plagiata and praeformata; hence I have 

 preferred not to use it as even sectional, but to preserve Staudinger's sequence of species. 



The larvae, so far as known, are of moderate proportions or rather slender, nearly cylindrical, with 

 distinct lateral ridge and transverse skin-folds. They feed chiefly on species of Hypericum. The pupae are 

 slender, with long tongue- and leg-case (projecting free and reaching nearly to the anal end) and are enclosed 

 in slight, transparent cocoons. The moths are often double-brooded. They are in general larger and more 

 brightly coloured than those of the preceding genus. 



Anattis is distributed throughout the greater part of the Palearctic Region and North India. 



A. lythoxylata Hhn. (8 a). Easily distinguished by its bright reddish ochreous colour. The markings lythoxylata. 

 consist of fine darker transverse lines, the subbasal and a pair of antemedian curved, three postmedian (the 

 central of them sometimes obsolescent) crenulate, and two fine, somewhat irregular subterminal arising fi-om 

 an oblique dark apical shade. Hindwing only with an indistinct, curved postmedian line. Both wings usually 

 with an obscure cell-mark. Local in the French Alps, Italy, Valais, Transsylvania and Bosnia and in Northern 

 Asia Minor and Transcaucasia. A mountain species, occurring at altitudes of 1400 — 1800 m in late August 

 and September. The foretibial claw is slender and was overlooked by Lederer.
