vary from exlremely elongate (as in the subgenus Chlorochjsla) lo sLout and rugose (as in some Culosti(jia), 

 some of the more slender larvae showing projecting anal points similar to those of the Lohopliora group. 

 The pupae of many species hibernate and these are nearly always enclosed in earther cocoons and agree with 

 most subterranean pupae in their glossy surface and red-brown or blackish-brown colouring. Those of the 

 earlier subgenera, howevei' {Gidaria, sens, str., to Dijsstroma, which constitute Ledkrer's group A, with exserled 

 cf anal clasps), usually pass quite a brief period in the pupal state, spun by a few threads among leaves, 

 and are often green in colour and on an average of a somewhat more slender texture. 



The genus Cidariu is of world-wide distribution. The species which penetrate furthest into the Arctic 

 Region belong here and so do some of the inhabitants of Tierra del Fuego. 



Subgenus Cidaria Tr. Face without cone of scales. Areole double. Discocellulars strongly oblique, 

 not biangulate. 



C. fulvata Forst. (= cuspidata Tlmhg) (8 g). Forewing in the name-typical form rather deep yellow, fulvata. 

 Hindwing yellowish white, unmarked, with fringe more yellow. Distributed throughout the greater part of 

 Europe, Asia Minor, Transcaucasia, N. Persia, the Altai and Kentei Mountains. — ab. degenerata ah. nov., degenerata. 

 founded on a specimen taken in the Isle of Man and figured by .Mosley and by Barrett, has nearly the 

 coloration of the following form, but the median band is dark and very much narrowed and broken into a 

 larger anterior and smaller posterior section. — distinctata Stgr. (8 g, as distinctaria) has the forewing less disiinctata. 

 mixed with red-yellow, the basal patch, however, whitly red-brown, the median band similarly coloured, usually 

 narrower (sometimes much narrower) in its posterior part than in fulvata, and there is a subterminal row of 

 brown spots. Central Asia: Zerafshan, Ferghana, Issyk-kul, etc. — Larva . rather long and slender with 2 well- 

 developed anal points, bluer green dorsally, yellower green ventrally, with yellow lateral line; head rather 

 small, prothorax slightly swollen. On rose in May. Pupa spun by a few threads among leaves; bright yellow- 

 green, wings more grass-green, dorsal line scarcely darkened, a whitish subdorsal; cremaster reddish brown. 

 On the wing at the end of June and in July. 



C. nugata Feld. ( = kashmirica Moore) (1 3 o). I have only seen figures (Felder's and a copy of Moore's nugata. 

 type), both representing the ?, and am not sure that this is anything more than a slight modification o[ fulvata 

 distinctata. Rather larger, the basal patch and median band rather lighter red-brown, the former less entirely 

 filled in (intermediate towards typical fidvata), the latter apparently sometimes (Felder's figure) broader. 

 Hindwing sometimes with traces of a dark postmedian line which is entirely wanting in fulvata and distinctata. 

 Kashmir. 



C. ochracearia Leech{:^ propinqua Warr.) (13 o) cf. Much deeper-coloured than fulvata, bright reddish ochracearia. 

 fulvous, the ground-colour of the hindwing not darker than that of the forewing; forewing with basal area 

 sometimes and median area usually darkened with red-brown, marginal area (except the pale apex) usually 

 much clouded with red-brown, a pale subterminal line present, though indistinct in places. Hindwing with 

 traces of an angled postmedian line. ? unknown. Distributed in W. China (Omei-shan, Ta-chien-lu, etc.). The 

 shape of the median band seems to differentiate it Sufficiently from both the preceding species; proximally 

 the band is scarcely dentate, except that it has a single, pointed projection inwards in the middle; distally 

 its central projection is single, not double. The ? will probably prove to be much lighter and the species 

 may have to be united with the following. 



C. ochripennis nom. nov. (= ochreata Stgr. nee Moore). From the description it is clear that this is ochripennis. 

 closely allied to the preceding, but the cf is described as deep ochreous-brown, the inner edge of the median 

 band has a very sharp angle in its middle, the projection in its outer edge is broader and rounder than in 

 fulvata. All else seems to agree essentially. The ? is larger, dark straw-yellow with darkened median band 

 and strongly marked miderside (that of the cf is weakly marked). Koko-Nor district, Tibet. 



C. fractistriga Alpk, described from a single worn ? and doubtfully referred by its author to Epifidonia, fraeiisiriga. 

 probably rather belongs here, as Leech suggests. Both wings bright orange yellow, the forewing with fusces- 

 cent antemedian and postmedian lines, the former curved, the latter commencing rather near it on the costa, 

 but outcurved, strongly angled at the 3''' radial, then again slightly curved, but running nearly perpendicularly 

 to the hindmargin; tiie convexity of both the curves is directed towards the base of the wing. Hindwing un- 

 marked. Forewing beneath more strongly mixed with grey, the postmedian straighter. Ou-pin (Gan-su), taken 

 on 6 July. 



Subgenus Lgitcometra subg. nov. Face with projecting scales. Palpus strong. Metathorax crested. Fore- 

 wing with areole double. Hindwing with discocellulars biangulate. cf with strongly exserted anal clasps.
