hindwing is narrower and proportionately more strongly widened before the tail (recalling P. latreillei), the 
scent-fold is shorter and the wool contained in it somewhat darker; the harpe is quite different: it, is dentate 
and terminates distally in a semicircular fold, curved upwards. The $ according to Oberthur is greyish ochre- 
colour. — West China, only a few specimens known. The species doubtless occurs also in South-Eastern China, 
as the following species from Formosa is a very near ally of impediens.

P. alcinous is distributed from Japan to West China and Tonkin. The scent-wool of the $ in all the 
forms is almost black. The harpe has proximally a simple or dentate process and ends distally in a point or a 
tooth. Larva olive-brown, with numerous dark, light-edged spots; on the 6. and 7. segments a very broad red- 
white oblique girth, which is dorsally interrupted or strongly constricted; the tips of the tubercles reddish, the 
upper lateral projections of the prothorax pale red with dark tips. According to Pryer in Japan on Cocculus 
thunbergi. The butterfly very common, and easy to catch on account of its slow flight; spring to autumn. —-
