0. nasifera Warr. (IJ a) somewlial resembles tlie most sharply-marked 'periholata, with the ground- nasifera. 

 colour slightly more whitish, but differs at once in the much more sharply pointed distal projection of the 

 median band. The basal line is also less straight, being strongly bent basewards at both ends, the antemedian 

 line is somewhat angled basewards on the median vein, forming curves anteriorly and posteriorly to this, and 

 the subterrainal line is not quite so straight. Moreover the discal dot is accompanied by a second fas in 

 bipuncfaria, etc.), which is scarcely ever the case in periholata. Inhabits the NorLh-weslern Himalayas in June. 



0. coelinaria Grasl. (8 c). Considerably larger than periholata, basal line less oblique, often less strongly coelinaria. 

 darkened, distal edge of median band rather strongly incurved between the radials, but with a much less pro- 

 nounced, double distal projection between the 3^"^ radial and 2"'' median. The median band is in general more 

 broadly darkened, leaving only a narrow pale shade in the centre, and even this is seldom extremely pale; 

 discal dot usually double, as in hipunctaria, but both minute. A variable species in coloration, particularly as 

 regards the colour of the area distally to the median band, which may be almost pure white or strongly mixed 

 with brown or ferruginous. The typical form, as described and figured by Gbaslin, has this area whitish, with 

 grey lines, only the first of them (nearest the median band) fulvous-brown; the median band itself very dark, 

 nearly black. The specimen was bred from the south of the Departement of Pyrenees-Orientales and — according 

 to its author and Monsieur Oberthur — has never occurred at Vernet-les-Bains, although the latter possesses 

 2 cfd" agreeing with it from Spain (Escorial). It must, I think, be a rare form. — jugicola Stgr. (=: vernetaria jugicola. 

 Ob.) is the common form of the species, with the median band lighter and the distal area (especially in the ??) 

 more or less strongly shaded with brown or fulvous. This is not only found in Castile, as Staudinger gives 

 in his Catalogue, but also prevails at Vernet-les-Bains, whence OBERXHiJR described and figured it. My own 

 series, from various Spanish localities, shows a good deal of valuation, some examples approaching — though 

 not reaching — the type form. — gerardini Ob. is a more melanotic form from the Basses Pyrenees with the gerardini. 

 hindwing almost uniformly blackish brown, the paler parts of the forewing also darkened, giving to the entire 

 wing a more uniform, more sombre appearance. In particular, the subbasal area is very little lighter than 

 the median. Staudinger in 1870 described this form as jugicola var., but in his latest Catalogue he wrongly 

 confounds it with typical coelinaria. — coelinaria is confined to the Pyrenees and Spain and flies in July; the 

 race gerardini occurs at elevations of 1000 to 1300 m. 



0. kashghara Moore (6 h) is a narrow-winged species and more weakly marked than most of the genus, kashghara. 

 the antemedian and postmedian lines being accompanied by very little dark shading in the central area; their 

 form is shown in our figure. The very oblique basal line is rather indistinct except at the costal margin; 

 the oblique apical streak is obsolete, but there is a dark mark at the costal extremity of the (almost obsolete) 

 sub terminal line. Discovered at Chiklik, south of Yarkand, at 4310 m. elevation, on 3'''' June; apparently 

 distributed in the Thian-shan range. 



0. similaria Leech (11a) from Western China (Ta-chien-lu, Wa-shan and Ni-tou), May — July, resembles similaria. 

 a large periholata, but has the hindwing whitish, merely somewhat shaded with grey basally and towards inner 

 margin, and shows, like coelinaria, a pronounced inward curve between the radials in the postmedian line of 

 the forewing — somewhat deeper, indeed, than in that species. The pale band in the middle of the central 

 area is rather sharply defined and nearly white and contains usually two very small discal dots. A whitish 

 line, or narrow band, runs between the median band and the narrow whitish subterminal line. — erschoffi erschoffi. 

 Alph. (8 c) is a somewhat more whitish, less dark-marked form from Koko-Nor and the Amdo district, with 

 the hindwing still clearer whitish, the whitish band between the median band and subterminal of the forewing 

 broader and more conspicuous and the discal dot single. I have seen very few, and am not sure whether 

 the distinctions will prove constant. If not, Alpheraky's name (published June 1897) must sink to Leech's 

 (May 1897). 



0. integraria Stgr. (II a). Forewing with distal margin more oblique, the apex thus appearing somewhat integraria. 

 sharper. The three fuscous bands (bounding the basal and median areas) well-defined, the first bent outwards 

 in the middle, the second and third formed somewhat as in periholata or simularia, but the third is of almost 

 uniform breadth throughout; preceded and followed respectively by distinct fulvous-brown shades, which are 

 characteristic of this species, especially of the cT. The central part of the median area is almost clear white 

 and contains two large discal dots, which are almost or entirely confiuent. Hindwing dirty whitish. ? smaller 

 and still narrower-winged. Samarkand in July, at about 3000 m. 



0. sartata Alph. (6 h) is very similar to integraria, which Alpheraky thought was merely an aberration sartata. 

 of it, but the margins of the central area are more dentate, the dark bands which this area contains are less 

 sharply defined inwards and the fulvous bands which bound the median area are entirely wanting. Hi district 

 to Ferghana, flying in June in the mountains.
