a rather broad pale band, containing the discalraarlt; its narrow proximal and broader diatal parts according 

 to tlie figure darker than in any pulchrata which I have seen. Hindwing as in pulchrata. Koko-Nor, Tibet. 



0. latifusata Walk. (= naemata Feld) and its close ally niphonica stand somewhat apart From all other lalifusata. 

 known species, but I think PiJiNGELER has found the best position for them, at least provisionally. The shape, 

 gloss and pattern of the forewing agree well with Ortholitha; the hindwing has the costal margin scarcely so 

 elongate as in most of the species and latifusata is also aberrant in having the discocellulars more or less 

 angulated, on account of an inward curve in the second discocelhilar. latifusata has the forewing proximally 

 and especially medially of a duller, slightly darker, less purplish brown than the here figured ignoiata, the 

 distal area in the cf nearly as dark as the median, in the ? largely whitish, at least proximally; the projection 

 in the postmedian is perhaps on an average more strongly rounded. Hindwing grey with wavy white hnes 

 beyond the middle. N. W. Himalayas and many localities in W. China. 



0. niphonica Btlr. (:= suavata Chr.) (7 e) has the discocellulars normal, obHque, the basal and median areas niphonica. 

 of the forewing usually more reddish brown, the latter darkening distally, the distal area lighter yellowish 

 brown, usually becoming paler distally. Hindwing rather darker than in latifusata, with a generally more 

 conspicuous black discal dot and angulated postmedian line, the latter usually accompanied distally by a single 

 fine whitish line. No marked sexual dimorphism. Japan, Amur and N. India. — ignotata Stgi\ {^= ignorata ignoiata. 

 Stgr., nom. praeocc.) (8 i) from Koko-Nor probably belongs here, as the sexes are nearly alike; the curve in 

 the postmedian is, however, broader and romider and Staudinger's type had the forewing dark grey-brown, 

 distally light violet grey, hindwing grey, weakly marked. 



7. Genus: Miild^clia Alpli. 



Essential characters nearly as in Larentia, distinguished chiefly by the wing-shape, the hindwing in 

 particular being more strongly produced at the apex, sometimes almost pointed, the distal margin not crenulate. 

 From Kyrfolitha it differs in the pectinate (f antenna, from Ortholitha in the biangulate discocellulars of the 

 hindwing. Only a few Asiatic species are yet known. 



K. staudingeri Alph. (7 e), the type of the genus and the most characteristic species, recalls Kijrtolitha staudingeri. 

 ohstinata in the extremely irregularly-formed lines which limit the rather narrow central area of the forewing. 

 The ground-colour is pale cinereous with a slight tinge of brown, the basal and median areas and some ill- 

 defined shades proximally and distally to the median darker and browner; the zigzag lines which bound the 

 basal and median areas are sharply defined, blackish. Hindwing whitish cinereous proximally, somewhat more 

 brownish distally, with a black discal dot, a sinuous postmedian line and usually some more feebly expressed 

 lines beyond. Fringes of both wings dark-chequered. Discovered in the forests of pine (Picea schrenckiana) 

 along the Kungess in the first half of June, at elevations of 40UU — 7000 feet. Known only from the Western 

 Thian-shan and Issyk-Kul districts. 



K. oberthuri Alph. (11 a) differs in being rather more uniform in colour, the margins of the central 

 band much less irregular, the band itself rather broader, containing a conspicuous black discal dot and also 

 a thick curved black mark on the 3'''' radial vein from the end of the cell to the postmedian line. The Amdo 

 district (Myn-dyn-scha) is the only recorded locality, but the specimen which we figure (ex coll. Brit. Mus.) is 

 labelled Koko-Nor and the British Museum also possesses a small worn S from Yatung (Tibet) which seems 

 referable here 



oberthuri. 



K. lakearia 0&. (6 i) closely resembles oberthuri, which may possibly even be a form of it. lakearia, ukearia. 

 however, seems to be rather smaller, rather darker, more strongly marked (especially on the hindwing) and 

 with the postmedian line on both wings making a stronger projection behind the 3'''' radial vein. The median 

 band is of a somewhat more reddish brown. In the cf of lakearia, moreower, the distal margin of the hindwing 

 is rather more rounded than in that of oberthuri. Inhabits Western China (Ta-chien-lu, Pu-tsu-fong). 



K. productaria Leech (described as Oporabia) agrees entirely with Kuldscha in structure except thut productaria. 

 the antennal pectinations are longer; all the margins of the forewiug are slightly more rounded and the distal 

 margin of the hindwing is likewise more rounded in its anal half Altogether a duller insect, the wings being
