Hab. Timor (Wall.), N.W. Australia (Brit. Mus.).

Remarks.—The Australian specimens are smaller. The female of P. Œnomaus mimics this species, as has been already mentioned (p. 22). Both species were taken by myself on the same spot, and, though such large and conspicuous insects, they could never be distinguished without a close examination after capture. The female of this species differs very little from the male, being rather larger, with broader wings and less vivid coloration.

Hab. Amboyna, Ceram (♂, ♀) (Wall.).

Remark.—The largest specimens of this glorious insect are found in the island of Amboyna, where it is rather common, hovering about the forest pathways. It sometimes visits the gardens in the town of Amboyna.
