 preceded by yellowish scaling and a dark cloudy band; hindwmg yeUowish grey, dusted with darker; a dark

costaema- P. costaemacula Stgr. (= ? mandarins Leech) (71 h). From the description and also the shape of the

 spot in the angle at middle, running out into the pale fringe; hindwmg brownish marbled with grey; a dark 

 inner line; a double dark outer line filled in with white, followed by a dark fascia edged by the pale subter- 

 minal line; discal mark composed of four white spots clustered round the dark discocellular. Amurland.
