CIDARIA. By L. B. Prout. 



costal spot; distal area generally rather paler, the large pale spot in its centre sometimes less well defined. 

 Apparently not variable. Japan; Yokohama; Korea; Gensan; Central China: Chang-Yang. Also known from 

 the Khasia-Hills. 



erebearia. C. erebearia Leech (13 c) is a glossy species of uncertain affinities. The coloration of the forewing rather 



I'ecalls that of dark specimens of Phileremc vafhH but the hindwing is narrower, smooth-margined. Perhaps 

 it should form a new subgenus near the beginning of Cidaria, as the cf genitalia are strongly developed. Face 

 without cone, palpus rather short and stoiit, d^ antenna pubescent, discocellulars strongly biangulate. Forewing 

 glossy-brown-grey with an admixture, in the paler parts, of shining, light blue-grey scales; about 15 black- 

 brown lines traverse the wing, those which bound the basal and median areas thickened; white subterminal 

 line only distinct at costa, accompanied by some dark spots. Hindwing with a single, rather weak curved 

 line. Underside with numerous lines, on the forewing weak. Pu-tsu-fong. 



ohsoletaria. C. obsoletaria H.-Sch. (= alpicolaria H.-ScL, gentianata Mill^) (10 a as alpicolaria). The markings very 



distinctive, the small basal patch of the forewing being closely followed by a broad dark bar, while the median 

 band, which becomes narrow and distinct at the hindmargin, is almost obliterated. Face without projecting 

 cone of scales. Antennal ciliation minute. The larva feeds in the unripe capsules of Gentiana lutea and other 

 gentians and according to de Rougement dies if they are opened; it is short and thick, flesh-coloured with 

 strongly developed tubercles and dark brown prothoracic and anal plates, altogether recalling a Tortricid larva. 

 August —September. The pupa is also short and thick, reddish yellow, with short cremaster. Imago in June 

 and July in the Alps, the Tyrol and Southern France. On account of the biology it should perhaps be referred 

 to the Perizoma group. 



perplexata. C. perplexata Leech has the median area broader, more brightly brownish, less interrupted, the succeed- 



ing band purer white in its anterior half, the apex anteriorly to the oblique apical dash white, the hindwing 

 white with more distinct lines, the underside more sharply marked than in ohsoletaria. Ta-chien-lu. 



casearia. C. casearia Const. (13c). Forewing creamy white; subbasal hne thick, blackish (especially at its edges), with 



a projecting tooth in the middle; median area hardly darkened, broader anteriorly than posteriorly, bounded 

 by two angular, deeply dentate grey bands which are darkened into quadrate blackish spots costally; discal 

 dot small and indistinct; distal area shaded with the same colour as the two bands, subterminal line zigzag, 

 white. Hindwing very pale grey with a postmedian series of blackish vein-dots, followed by a pale band; 

 subterminal not zigzag. Fringes dark chequered, especially on the forewing. Corsica, found at rest on the 

 stems of Alnus suaveolens. 



amhuslaria. C. atnbustaria Leech. Somewhat similar to the species which follow and apparently similar in structure 



except that the discocellulars of the hindwing are only very weakly biangulate. Size much smaller, coloration 

 about as in weakly marked taczanowskiaria, antemedian line less oblique, nearly straight (slightly curved), 

 subapical streak not well defined but merged in a dark cloud of which it forms the anterior edge and which 

 reaches to the 3'''* radial. W. China, perhaps also from Koko-Nor. 



taczanows- C. taczanowskiaria Ob. (=:pervagata Chr.) (10 m). Brown-grey with some tinge of reddish. Forewing 



kiaria. similarly coloured and marked to that of rejectaria, but taczanowskiaria is rather longer- winged, the antemedian 

 band somewhat straighter, postmedian line deeper black, tiie band proximally to it rather broader and darker, 

 the projection on the 1 ^' radial less sharp, the subterminal line much less dentate. The abdomen is built 

 more like that of Pelurgu comitata. cf antennal ciliation extremely minute. Palpus strong. Rather variable 

 in the lighter, brighter or darker colour. Amur, Ussuri and Japan. 



rogata. C. rogata Stgr. In size, colour and markings, as well as structure, similar to berberata. Subbasal 



stripe not bent on subcostal vein; antemedian weakly curved in S-shape, usually preceded by two blackish 

 lines; a short discal lunule sometimes present; postmedian almost straight, only extremely weakly curved and 

 with one or two quite small teeth distad near the costa. Hindwing usually with a broad, noticeably darkened 

 distal border. Ferghana. 



rejectaria. C. rejectaria Stgr. (:= interrogata Alph). Closely related to berberata, of which it may be a Darwinian 



form. Rather darker, less variegated, the black lines of the forewing finer and less intense, the postmedian 

 forming a less acute tooth on the 1 *' radial, the lines proximally to it closer together, more suggesting a 

 narrow band, which continues, more or less fully developed, to the hindmargin; subterminal line more distinct. 

 Underside of forewing dark glossy grey, costal margin to beyond the middle pale, discal dot and costal part 

 of postmedian line distinct; hindwing paler, with discal dot, postmedian line and a weak dark shade_ beyond. 

 Issyk-kul, Thian-shan and Amdo.
