_Remarks._—The Philippine form (_P. Kotzebuea_, Eschsch.) is rather larger and of a more uniform glossy black than those from other localities. _P. Theseus_, Cram., has been erroneously supposed to be the female of this species, whereas it is the female of one of the _Pammon_ group, belonging to a different section of the genus. De Haan figures _P. Theseus_ as _P. Antiphus_ ♀, in Verh. Nat. Gesch. t. 8. f. 2. As has been already pointed out, _P. Theseus_ mimics this species. 28. PAPILIO POLYPHONTES, Boisduval. _P. Polyphontes_, Bd. Sp. Gén. Lép. p. 268. _P. Hegemon_, G. R. G., List of Papilionidæ in B. Mus. _Hab._ Celebes, Batchian, Morty Isl. (♂, ♀) (_Wall._). _Remarks._—The markings vary from pure white to a smoky tint; but otherwise all the specimens from the above localities agree. De Haan gives (Verh. Nat. Gesch. t. 8. f. 4) a female of one of the _Pammon_ group as _P. Polyphontes_ ♀. 29. PAPILIO ANNÆ, Felder. _P. Annæ_, Feld. Lep. Nov. Philipp, p. 1. _Hab._ Mindoro (Philippines). 30. PAPILIO LIRIS, Godart. _P. Liris_, God. Enc. Méth. iv. p. 72; Boisd. Sp. Gén. Lép. p. 268; De Haan, Verh. Nat. Gesch. p. 38, t. 4. f. 3 (♀). _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. SECTION B. d. _Ulysses_ group. 31. PAPILIO ULYSSES, Linnæus. _P. Ulysses_, L., Cramer, Pap. Ex. t. 121. f. A, B (♀), t. 122 A (♀). _P. Diomedes_, Boisd. Sp. Gén. Lép. p. 202. _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. 32. PAPILIO PENELOPE, n. s. _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._).
