Hab. Sumatra, Borneo (♂, ♀) (Wall.), Java (Leyden Mus.).
Remarks.—My specimens have less white on the lower wings than is represented in Mr. Westwood’s figure. The female is of a brownish colour, with the same white markings as the male, but without any blue tinge. This species is very like Euplœa Rhadamanthus, one of the most common butterflies in all the above-mentioned localities. It is undistinguishable from that insect on the wing, though it flies very slowly, like the species it mimics.

Hab. Borneo (♂) (Wall.).
Remarks.—The last two species should probably form a distinct group, on account of the peculiar elongation of the cell of the lower wings. They both resemble dark species of Euplœa. P. Slateri is a quite distinct species from North India, to which Mr. Hewitson referred the present species as the female. All the specimens known of both species are, however, males.
