Remarks.—At Macassar I took only males of P. Encelades, and females of P. Deucalion at the same spot (a half-dry river-bed), and therefore conjectured that they might be sexes of one species, although so unlike. Some years afterwards, however, I took at Menado a fine male of P. Deucalion, which only differs in its rather smaller size and brighter colouring.
