Soc. Ent. Fr. (6) 8: xix TL: "Mou-Pin" [Baoxing, Sichuan] (original description) Description: both wings white on the upperside and pale yellowish to yellowish on the underside. Spring form: medium size. Male (Fig. 10F, H ): apical spot blackish with slightly whitish powder, merging as a small dark subtriangular spot on the apex. All discal spots and outer spots absent on the upperside (except for the 1st discal spot and outer spot sometimes rather faintly developed). The 2nd discal spot vaguely developed on the underside. Female (Fig. 10I ): apical spot brownish, partly merging as a subtriangular spot on the apex.

All veins strongly brownish powdered on both sides especially forewings on the upperside. Summer form: medium to large size. Resembles spring form but larger with rounder wing shape. The 1st discal spot of males (Fig. 10G ) present on both sides and the brown powder along veins is stronger in summer form of females (Fig. 10J, K ) than spring forms. Figure 10.
