Remark

Intraspecific colour variation of the disc of the hind wings exists in this species, with specimens showing bright yellow hind wings and others, milky white. The colour of the tegmina also varies to a great extent, from very dark forms, nearly black with yellow spots ringed with white, to very pale forms, nearly white with yellow spots or even nearly white with cloudy darker, brownish markings in place of the yellow spots. Conspecificity of the different forms was confirmed by the study of the male genitalia and corroborated by the fact that the different forms are sympatric, as illustrated by a series from Chiang Mai collected in June 1992 in Nagai & Porion (1996: figs 194–199). The comparison of the illustrations of the types specimens ( Figs 6A , 7A ) with the line illustration of Guérin-Méneville (1829) ( Fig. 8 ) which matches both type specimens is also very convincing.

Distribution

Northeastern India, southern China, northern Thailand, Laos, North and Central Vietnam. The species is recorded here from Laos for the first time.
