rina of

S.formosa is more evenly serrate, the valva is narrower, more curved ventrally, the costa is more arcuate, the cucullus is smaller, more quadrangular, the pollex-like extension is narrower, smaller, spine-like. The most conspicuous difference of the female genitalia of the two species can be found in the shape of the cervix bursae which is arcuate but not twisted in S. apocrypha, its terminal end projecting proximally while the cervix ox" S.formosa is twisted, its tip curved caudally. In addition, the dorsal plate of the ostium bursae is more elongate, ellipsoidal in S. apocrypha, the ductus bursae is longer, proximally less tapering than that of S. farmosa. S. apocrypha resembles also to S. t. taiwana but is smaller in size, more short-winged, its forewing ground colour is paler, with weaker, less irregular darker pattern; the hindwing of male whitish, but not as clear white as that of S. t. semialba. The male genitalia of S. apocrypha has, in comparison with those of S. t. taiwana and S. t. semialba, much shorter valvae with different shape, more triangular, broader, apically more acute harpe, shorter, triangular cucullus with smaller pollex-like lobe, much shorter aedeagus with significantly larger dorsal sclerotized plate of carina and significantly shorter, narrower tube of vesica with smaller, weaker terminal cornutus. The female genitalia of S. apocrypha differ strongly from those of S. taiwana by its lyriform, half-ring-like ventral plate of ostium bursae, having no medial prominence projecting ventrally, the ductus bursae is considerably shorter, the cervix bursae is proportionally larger and the corpus bursae has fine, ribbon-like signum. The dorsal and ventral plates of ostium bursae are almost equal, elliptical-discoidal in S. taiwana, the ventral plate has conical medial prominence projecting ventrally, the ductus bursae is considerably longer than those of S. apocrypha and S. farmosa and the signum is absent. Description - Male. Wingspan 32 mm, length of forewing 13 mm. I lead, thorax and forewing violaceous ash-grey, lateral side of palpi, collar at oase and thorax marked with dark grey and/or whitish streaks of groups of scales. Abdomen lighter greyish with grey-brown hairs, first tuft of dorsal crest dark brown. Basal and marginal fields of forewing irrorated with light brown and whitish grey s^úes, wing pattern rather indistinct. Ante- and postmcdial lines simple, strongly sinuous, defined by narrow, whitish grey /one. Median area narrow, more or less oblique, irrorated by brown-grey, darkest part of wing. Orbicular stigma strongly flattened, narrow, whitish with darker centre and fine, blackish, incomplete outline. Reniform stigma less visible, narrow, conjoined with orbicular by darker brownish patch, encircled finely with grey. Dark streak below cell less strong, running from base of orbicular to postmcdial line close to lower edge of cell. Marginal area more or less striolate, sublerminal line pale grey-brown defined by white streaks and dark brownish arrowheads producing characteristically variegated paUcrn. Terminal line ochreous-whitc, marked by fine dark grey arches; cilia as ground colour, spotted with white. Hindwing slightly transparent whitish, with a few darker scales at inner angle. Veins partly covered by brown, especially in marginal area. Discal spot clearly visible, narrow, arcuate, transverse line represented by slightly stronger spots on
