Description

P. szechenyi is distinguished by a very broad vitreous margin to the forewing, this band together with the submarginal one forming a broad distal area which is divided by a row of white contiguous half moons proximally sharply bordered with black; costal and hindmarginal spots filled in with pale red, of the costal ones at least the posterior. Hindwing with large, red, white-pupilled ocelli, broad black posterior area strongly irrorated with white, and two large black anal spots with blue filling, from which emanates forward an anteriorly vitreous grey and posteriorly black submarginal band. Underside of a peculiar greasy gloss, somewhat yellowish, most markings only feebly shining through. Shaft of antenna and fringes of wings whitish. Amdo (Kuku-nor), North-East Tibet.- germanae Aust. is a form in which both sexes, but especially the female, have the disc of the forewing shaded with black; hindwing with dark marginal band, the submarginal band separated into spots, the large blue-centred anal spots being accompanied further forward by two similar spots and a blackish subapical spot.
