Male: rather smaller than P. Ulysses. Upper wings with six black cottony patches, and all separate from each other; whereas in P. Ulysses there are seven, and the four lower ones are always united at their margins. The blue colour fills the discoidal cell, and generally extends beyond it at the extremity; the upper disco-cellular nervure not black-bordered as in P. Ulysses. Lower wings with the blue colour extending further along the abdominal margin, and not quite so far towards the outer angle.

Female: has the blue colour of the same form and extent as in P. Ulysses ♀, but of the same bright tint as in the male; the marginal lunules more deeply curved.

Expanse of wings 5 inches.

Hab. New Guinea, Waigiou, Aru Is. (♂, ♀) (Wall.).

Remark.—As all the other forms closely allied to P. Ulysses have received names (Telemachus, Montr., Chaudoiri, Feld., Telegonus, Feld., and Ulyssinus, Westw.), I have also given one to this form peculiar to New Guinea and the Papuan Islands, the distinctive characters of which, though very slight, seem sufficiently constant.

33. Papilio Telegonus, Felder.

P. Telegonus, Feld. Lep. Fragm. p. 50.

Hab. Batchian, Gilolo (♂, ♀) (Wall.).

Remark.—A very distinct species, separated from P. Ulysses by the extent of the cottony patch on the upper wings, and by the different form and colour of the blue markings.

34. Papilio Telemachus, Montrouzier.
