ous forewings with weaker pattern. The male genitalia of O. radiata differ from those of O. arenicola by its smaller, more elongated, less quadrangular vesica penis and the shorter, apically more rounded uncus, otherwise the genitalia of the two species are very similar with rather wide range of variation, overlapping in several features. The female genitalia of the two species are very close, only the lamina antevaginalis is narrower, barlike in the new species while much broader, arcuate in O. arenicola. Description. Wingspan 29-38 mm, length of forewing 13-18 mm. Head and thorax pale grey, mixed with whitish and darker grey-brown, lateral sides of palpi, collar, tegulae and thoracic tufts finely marked with dark grey. Antennae of male shortly bipectinate, those of female fine, filiform. Abdomen somewhat paler, more brownish, dorsal crest absent. Forewing of male elongated, rather high triangular, with apex pointed, ground colour pale ashy grey, medial area irrorated with ochreous-brown and darker grey, basal and marginal fields variably strongly suffused with whitish. Scaling finely reticulate, ante- and postmedial crosslines less distinct, interrupted, represented by some short brownish grey streaks and lines, streaks of submedian fold and inner margin fine, long. Stigmata present, orbicular small, flattened, reniform large, with long, double-peaked projection outwards and a shorter, simple inwards, both stigmata finely, partly encircled with dark brownish; claviform small, encircled with blackish. Subterinal obsolescent, strongly sinuous, marked with fine, dark brown arrowheads and a greyish zone at outer side. Veins covered with blackish in marginal area, terminal line fine, rather diffuse, dark grey-brown, cilia whitish, striolate with brown. Hindwing shining, pure white, veins finely ochreous, discal spot small, diffuse, transverse line a row of brownish spots on veins. Terminal line strong, dark brown, cilia white. Underside of both wings chalky white, sparsely irrorated with pale grey, discal spots and remnants of transverse lines diffuse but present on both wings. Female similar, its wings somewhat broader, more uniformly greyish, without whitish suffusion. Claviform longer, more sharply defined, hindwing paler, more transparent. Male genitalia (Figs 21-22. 25). Uncus relatively short, flattened, lanceolate, with apex rounded, basal part with fine, rounded dorsal hump. Tcgumen broad, penicular lobes small, fultura deltoidal, symmetric or slightly asymmetric, vinculum strong, short, more or less V-shaped. Valva elongated medially slightly constricted, with fine, rounded triangular costal lobe; cucullus small, rounded triangular with apex pointed, corona consisting of strong setae arranged into sparse rows. Sacculus broad, long, clavus a finely setose surface. Harpe broad, flattened, sclerotized, ventral extension of costal plate more or less triangular, relatively small. Aedeagus cylindrical, thick, arcuate, carina with a strong, apically rounded dorsal plate. Vesica short, everted ventro-laterally, sacculiform with rounded conical apex and a semiglobular subbasal diverticulum. Cornutus absent; ductus ejaculatorius projected laterally. Female genitalia (Fig. 38). Ovipositor short, broadly conical with angular posterior papillae anales. Lamina antevaginalis narrow, bar-like, ductus bursae broad, rather short, flattened, sclerotized, anterior part slightly dilated. Cervix bursae small, more or less rounded, smooth, corpus bursae long, narrow, hyaline. Remarks. The species was illustrated as O. fissilis CHRISTOPH by ALPHÉRAKY (1897, plate VIII, Fig. 9.) Distribution. The distribution of this species is poorly known. We could study only few specimens of old collections from Kazakhstan and from the neighbouring region of Chinese Turkestan.
