Part 10

This remarkable species must be very rare, as I never saw it in any part of the New Guinea district that I visited; nor was it seen during the exploration, a few years ago, by a Dutch steamer which visited the part of the coast where the only specimen known was said to have been obtained.

5. ORNITHOPTERA URVILLIANA, Guérin.

_Papilio Urvilliana_, Guér. Voy. de la Coquille, Lép. t. 13. f. 1, 2, ♂.

_O. Urvilliana_, Boisd. Sp. Gén. Lép. p. 175.

_Hab._ New Ireland (_Paris Museum_).

b. _Pompeus_ group.

6. ORNITHOPTERA REMUS, Cramer.

_Papilio Remus_, Cr. Pap. Ex. t. 135. f. A, t. 136. f. A (♀), t. 386. f. A, B (♂); Fab. Syst. Ent. iii. 1. p. 11.

_O. Remus_, Bd. Sp. Gén. Lép. p. 176. _Papilio Panthous_ ♂, Clerck, Icon. t. 18 (♀).

_Hab._ Amboyna, Ceram, Gilolo, Morty Island, Sulla Island, Celebes (_Wall._).

The specimens above quoted agree well with Cramer’s figures. The female from the Sulla Islands differs only in having more yellow towards the anal angle of the lower wings. The specimens figured by Cramer in pls. 10, 11, under the name of “_Hypolitus_” seem to be a remarkable variety, in which the female has much of the character of the male. Messrs. Doubleday and G. R. Gray have adopted _Panthous_ as the specific name of this insect; but this name was first used by Linnæus for the female of _Priamus_ only, in the 10th ed. of the ‘Systema Naturæ’ (1758). Clerck (in 1759) adopted the name, but supposed he had found the male in the female of _Remus_. Linnæus, in Mus. Lud. Ulric. (1764), and in the 12th ed. of the ‘Systema Naturæ’ (1766), adopts this error, so far as referring to Clerck’s two figures; but in both these works his description refers only to the female of _P. Priamus_, indicating that the supposed other sex (_P. Remus_) was not known to him personally. The name of _Panthous_ must therefore altogether drop, it having been applied to this species only through a double error—first, that of Linnæus, in supposing his _Panthous_ to be distinct from _Priamus_, and then that of Clerck, in thinking that a female _Remus_ was the male of the Linnean _Panthous_.

7. ORNITHOPTERA HELENA, Linnæus.

♂. _P. Helena_, Cram. Pap. Ex. t. 140. f. A, B. _O. Helena_, Boisd. Sp. Gén. Lép. p. 177.

♀. _P. Amphimedon_, Cram. Pap. Ex. t. 194. f. A. _O. Amphimedon_, Boisd. Sp. Gén. p. 176.

_Hab._ Amboyna and Ceram (_Wall._).

The females from these localities are always sooty, with the spots and markings on the hinder wings of a dull buff-colour even in the freshest specimens.

_a._ Local form _Bouruensis_.—_Male_: exactly resembles the Amboyna specimens, except that the yellow patch is more variable in form and extent.

_Female_: nearly black, and with the markings on the lower wings almost as pure and deep yellow as in the males: size a little smaller than in the type.

_Hab._ Bouru (_Wall._).

_b._ Local form _Papuensis_.—_Female_: sooty black, the two first branches of the subcostal nervure margined with whitish near their origin; markings of the lower wings of the same tint of orange-yellow as is _O. Helena_ ♂, but not so glossy.

_Male_ not known.

_Hab._ New Guinea, Salwatty (_Wall._).

_c._ Local form _Celebensis_.—_Male_: wings a little more pointed than in _O. Helena_; yellow patch of lower wings extending nearer to the posterior margin, and bounded towards the abdominal margin by the first branch of the median nervure. Beneath, having the nervures between the discoidal cell and the outer border ashy-margined.

_Female_ not known.

_Hab._ Macassar (Celebes) (_Wall._).

_Remarks._—Of these three local modifications of _O. Helena_, the first is very distinct in the female, but not separable in the male sex. Of the second and third, only one sex is known; and they may very probably prove to be well-marked species when more materials are obtained.

8. ORNITHOPTERA LEDA, n. s.

_Male_: upper wings elongate, triangular, glossy black, quite uniform and immaculate; the outer margin delicately white-marked at the termination of the nervures. Lower wings yellow, as in the allied species, with a black border about the same width as in _O. Pompeus_ on the outer and abdominal margins, narrower on the inner margin; the posterior scalloping of the yellow patch not so deep as in _O. Pompeus_, and having a spot at the anal angle connected more or less with the margin.

The under surface differs from that of _O. Pompeus_ by the ashy margins of the veins of the upper wings being entirely absent, and in having much less white on the outer edge. There are no submarginal spots except the anal one, much red at the base of the wings, and no black spots on the abdomen.

_Female_: this sex varies very much, some having the upper wings immaculate, while others have the veins about the end of the discoidal cell broadly margined with whitish. The marginal series of spots on the lower wings vary as they do in _O. Pompeus_ and _O. Amphrisius_. The best distinction from _O. Pompeus_ (♀) seems to be the more elongated wings, the less crenellated margin, and the more produced outer angle of the lower wings. The yellow patch is also of a deeper colour both on the upper and under surfaces.

_Hab._ Celebes (Macassar and Menado) (_Wall._)

9. ORNITHOPTERA POMPEUS, Cramer.

_P. Pompeus_, Cr. Pap. Ex. t. 25. f. A (♂). _P. Minos_, Cr. Pap. Ex. t. 195. f. A (♀). _P. Heliacon_, Fab. Ent. Syst. 3. i. p. 19, 60.

_O. Heliacon_, Boisd. Sp. Gén. Lép. p. 178.

_Hab._ Sumatra, Borneo, Java, Lombock (_Wall._), India (var.).

_Remark._—The form that occurs in India, in its more elongate wings and darker colouring, approaches very closely to _O. Rhadamanthus_.

10. ORNITHOPTERA NEPHEREUS, G. R. Gray.

_P. Astenous_, Eschscholtz, Voy. Kotzebue, t. 4. f. A, B, C. (nec Fab.).

_O. Nephereus_, G. R. G., List of Lep. B. M. Papilionidæ, p. 6.

_Hab._ Philippine Islands.

_Remark._—This is quite distinct from _O. Rhadamanthus_, Bd., with which it has generally been identified.

11. ORNITHOPTERA MAGELLANUS, Felder.

_O. Magellanus_, Feld. Lep. Nov. Phil. p. 11.

_Hab._ North of Luzon (Philippines).

_Remark._—This fine species has a beautiful opalescent glow on the lower wings when viewed obliquely.

12. ORNITHOPTERA CRITON, Felder.

_O. Criton_, Feld. Lep. Fragm. p. 49.

_Hab._ Batchian, Ternate, Gilolo, Morty Island (_Wall._).

13. ORNITHOPTERA PLATO, n. s.

_Male_: resembles _O. Criton_ in the form and extent of the yellow patch, but the upper wings differ in having the outer half of a lighter tint; on the under surface this outer half of the wing is of a light ash-colour. Abdomen almost wholly black beneath. No red patches at the base of the wings, or any red collar.

_Female_ unknown.

_Hab._ Timor (_Wall._).

This is a very distinct species, though at first sight resembling several others. I obtained a single male specimen only.

14. ORNITHOPTERA HALIPHRON, Boisduval.

_O. Haliphron_, Bd. Sp. Gén. Lép. p. 181 (♂); Felder, Lep. Fragm. p. 37, Taf. ii. f. 2, 3 (♂, ♀).

_Hab._ Macassar (Celebes) (_Wall._).

15. ORNITHOPTERA AMPHRISIUS, Cramer.

_P. Amphrisius_, Cr. Pap. Ex. t. 219. f. A; Godardt, Enc. Méth. ix. p. 27, pt.

_O. Amphrisius_, Bd. Sp. Gén. Lép. p. 178.

_Hab._ Malacca, Java, Borneo (_Wall._).

This may be readily distinguished from the allied species by the upper wings in the male being yellow-marked, and by the absence of red spots at the base of the wings beneath in both sexes.

c. _Brookeana_ group.

16. ORNITHOPTERA BROOKEANA, Wallace.

_O. Brookeana_, Wall. Proc. Ent. Soc. 1855, p. 104; Hewitson, Ex. Butt. Papilionidæ, i. f. 1. _Papilio Trogon_, V. Voll. Tijdschrift voor Ent. 1860, p. 69, pl. 6.

_Hab._ Borneo (Sarawak) (_Wall._), Sumatra (_Leyden Museum_).

_Remarks._—I have been in much doubt about the position of this remarkable species, and was for some time inclined to place it among the Papilios. It agrees, however, far better with _Ornithoptera_ in the form and stoutness of the wings, the long stout and curved antennæ, the red collar and patches at the base of the wings beneath, the abdominal fold, and the flight and general appearance. It is powerful on the wing, and occasionally settles on the ground in damp sunny places. It inhabits the interior of North-west Borneo and the mountains of West Sumatra. The female is unknown. It is peculiar in the great length of the discoidal cell of the wings and its altogether unique style of coloration, and must be considered as the type of a distinct group of the genus _Ornithoptera_.

PAPILIO.

This is without doubt the finest and most remarkable genus of Diurnal Lepidoptera. About 360 species are now known, all, except ten, being tropical or subtropical. I have given at p. 23 the characters of the sections and groups into which I divide the Malayan species.

SECTION A.

a. _Nox_ group.

17. PAPILIO NOX, Swainson.

_P. Nox._, Sw. Zool. Ill. pl. 102; Horsf. Lep. Ins. E. I. C. pl. 1. f. 1; Boisd. Sp. Gén. Lép. p. 277.

_P. Neesius_, Zink. Nov. Act. Acad. Nat. Cur. xv. t. 14. f. 1.

_Hab._ Java (♂, ♀) (_Wall._), Penang (♂) (_Brit. Mus._).

18. PAPILIO NOCTIS, Hewitson. Tab. V. fig. 1 (♂)[12].

Footnote 12:

In all the Plates, the wings on one side of each figure are detached from the body, and represent the _under surface_ of the same insect. In one case only (Tab. VII. f. 1.) the upper surfaces of two varieties of the same species are given.

_P. Noctis_, Hewits. Proc. Zool. Soc. 1859, p. 423, pl. 66. f. 5 (♀).

_Male_: differs from the same sex of _P. Nox_ by the broader apex of the fore wings, and by the hind wings being more elongate, more glossy, and especially by the entire nondentated hinder margin.

_Hab._ Borneo (Sarawak) (_Wall._), (♂, ♀ Mus. nost.)

19. PAPILIO EREBUS, Wallace.

_P. Nox_, var., De Haan, Verh. Nat. Gesch. t. 5. f. 3 (♀).

_Hab._ Malacca (_Wall._), Banjermassing, Borneo (_De Haan_).

_Remarks._—I am somewhat doubtful of the species, the female only being known; but it differs so strikingly from the same sex of _P. Nox_ and _P. Noctis_ (the former of which seems very constant), that I think it better to separate it in order to draw attention to other specimens that may exist in collections. It differs from _P. Nox_ (♀) by its narrower and more elongate hind wings, which are black, glossed with steel-blue; the fore wings are black, with the veins beyond the cell clearly white-margined. The lower margin is also much less strongly dentated.

20. PAPILIO VARUNA, White.

♀. _P. Varuna_, Wh., Entomologist, 1842, p. 280; Westw. Ann. Nat. Hist. ix. p. 37. _P. Chara_, Westw. Arc. Ent. pl. 66. f. 2.

♂. _P. Astorion_, Westw. Ann. Nat. Hist. ix. p. 37; Arc. Ent. pl. 66. f. 1.

_Hab._ Pulo Penang, Sylhet.

21. PAPILIO SEMPERI, Felder.

_P. Semperi_, Feld. Lep. Nov. Philipp, pp. 1, 11.

_Hab._ Luzon, Philippines (♂, ♀).

N.B. The _Philoxenus_ group peculiar to India follows on after these.

b. _Coon_ group.

22. PAPILIO NEPTUNUS, Guérin.

_P. Neptunus_, Guér. Deless. Voy. dans l’Inde, p. 69, t. 19 (_P. Saturnus_).

_Hab._ Malacca, Borneo (♂, ♀) (_Wall._).

23. PAPILIO COON, Fabricius.

_P. Coon_, Fab. Ent. Syst. iii. 1. pp. 10, 27; Don. Ins. China, pl. 24. f. 1; Lucas, Lep. Ex. t. 6. f. 2; Boisd. Sp. Gén. Lép. p. 201.

_Hab._ Java, Sumatra (_Wall._), Borneo (_De Haan_).

_Remarks._—The specimens from Sumatra are constantly larger than those from Java. The Indian form, in which the markings are red instead of yellow, with other differences, I consider a distinct species, for which I propose the name of _P. Doubledayi_, after the late Mr. Edward Doubleday of the British Museum[13].

Footnote 13:

PAPILIO DOUBLEDAYI, Wallace. (_P. Coon_, var., B. M. Cat.)

_Above_: upper wings as in _P. Coon_, but the base darker. Lower wings broader than in _P. Coon_; the white spot in the cell toothed below, and divided by one or two faint blackish lines, cut off at the middle of the cell by the black triangular basal patch. The marginal spot next within the tail wanting; the two anal spots, end of abdomen, and its rings (which are yellow in _P. Coon_) red; collar behind the eyes and palpi (which are black in _P. Coon_) also red.

_Beneath_: base of lower wings broadly black; white spots all much broader and rounder than in _P. Coon_; sides of the thorax, end of the abdomen, and the marginal spots in the caudal and anal region red.

The female differs in a corresponding manner from _P. Coon_ ♀. Size about the same.

_Hab._ Moulmein, Assam.

c. _Polydorus_ group.

24. PAPILIO POLYDORUS, Linnæus.

_P. Polydorus_, L.; Clerck, Icon. t. 33. f. 3. _P. Leobates_, Reinw. Verh. Nat. Gesch. Zool. t. 6. f. 3 (♀).

_Hab._ Ceram, Matabello Island, Bouru, Batchian (♂, ♀) (_Wall._).

Local form or variety _a_.—The white markings on the fore wings forming a patch below the cell; red spots on the hind wings nearer to the posterior margin and that next the anal angle larger.

_Hab._ Ké Island, Aru Island (♂, ♀) (_Wall._).

25. PAPILIO LEODAMAS, n. s. Tab. V. fig. 2 (♂).

_P. Polydorus_, in Brit. Mus. List of Papilionidæ, p. 10.

_Male._ Above, glossy black, upper wings immaculate (the veins pale-margined in the female). Lower wings with a rounded white spot divided into six parts by fine nervures, of which the outermost and that in the cell are sometimes reduced to points; marginal row of red spots obscured with black, and but faintly indicated.

Beneath, the white patch has a small red spot attached to the part next the anal angle; and the marginal row of six red spots are clearly marked, that at the anal angle being twice the size of the rest. Wings short, much rounded, scarcely or not at all produced in the caudal region.

Expanse of wings 3¾ in. to 4 in.

_Hab._ New Guinea, Mysol (♂, ♀) (_Wall._), Rockingham Bay (Australia), (_Brit. Mus._, ♀).

26. PAPILIO DIPHILUS, Esper.

_P. Diphilus_, Esp. Ausl. Schmett. t. 40. f. 1. P. _Polydorus_, Boisd. Sp. Gén. Lép. p. 267; and most authors.

_Hab._ Java, Malacca (_Wall._), Philippine Islands, India.

_Remarks._—The specimens from Manilla are larger, and the females paler-coloured, than those from other localities, all of which have slight characteristic peculiarities; but they also vary in the individuals from each locality, so that no perfect segregation of local forms has yet taken place.

27. PAPILIO ANTIPHUS, Fabricius.

_P. Antiphus_, Fab. Syst. Ent. iii. 1. pp. 10–28; Boisd. Sp. Gén. Lép. p. 266.

_Hab._ Sumatra, Borneo, Lombock, Java (_Wall._), Philippine Islands.

_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._).

_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.

_P. Telemachus_, Mont. Ann. de la Soc. d’Agriculture de Lyon, 1856, p. 395.

_Hab._ Woodlark Isl. (S. E. of New Guinea).

_Remark._—This is a small species (exp. 4 in.), with less blue on the lower wings.

e. _Peranthus_ group.

35. PAPILIO PERANTHUS, Fabricius.

_P. Peranthus_, Fab. Syst. Ent. iii. 1. p. 15; Don. Ins. China, pl. 26; Lucas, Lep. Ex. t. 12. f. 2; Boisd. Sp. Gén. Lép. p. 203.

_Hab._ Java, Lombock (_Wall._).

36. PAPILIO PERICLES, n. sp. Tab. VI. fig. 1 (♂).

Wings more elongate, and upper wings more pointed, than in _P. Peranthus_.

_Above_: black, the basal half of a silvery blue, greenish towards the base of the costa, and purplish on the outer margin, where on the lower wings it shades off into separate scales. On the submedian and two lower branches of the median nervure are elongate black cottony patches as in _P. Ulysses_, the lower ones joined at the base, the upper one separate; above these the outer margin is of a brown-black, with a few atoms of yellow and blue scales towards the apex; the blue colour extends beyond the discoidal cell of the upper wings in a line parallel with the outer margin, on the lower wings it rounds away to the anal angle, and below it are five submarginal lunules of blue atoms, the outer one almost obsolete, and that next the tail largest and most deeply coloured. Thorax and body green.

_Beneath_: as in _P. Peranthus_, but the posterior range of lunules margined with brilliant blue and orange brown.

Expanse of wings 3½ inches.

_Hab._ Timor (♂) (_Wall._).

37. PAPILIO PHILIPPUS, Wallace. Tab. VI. fig. 3.

_P. Peranthus_, var. A, Boisd. Sp. Gén. Lép. p. 204.

_Above_: basal half of the wings of a rich green-blue, the rest black, with a triangular patch at the apex of the uppers, formed of green atoms situated between the nervures; on the lower wings six large submarginal lunules, the lowest of which sends out some green atoms along the tail. The black cottony spot is of a different form from that of _P. Peranthus_, the separate patches being only joined in the middle, and two of them extending along the nervures in a point nearly to the discoidal cell.

_Beneath_: brilliantly marked with lunules of buff, black, and blue.

Expanse of wings 4½–5 inches.

_Hab._ Moluccas (_Wall._).

_Remarks._—My specimen from Ceram is of a greener tinge, and the colour extends a little beyond the end of the discoidal cell; that from Batchian is smaller, of a bluer tinge, and the colour of less extent. The species seems to be very rare.

38. PAPILIO MACEDON, Wallace. Tab. VI. fig. 2 (♂).

_P. Peranthus_, var. B., Boisd. Sp. Gén. Lép. p. 204.

Boisduval’s description sufficiently shows the remarkable differences of form, size, and colouring which this species presents, compared with that of which he considers it a variety. The female agrees with the male, except that the colours are a little less brilliant, and the cottony patches of the fore wings are absent.

Expanse of wings, ♂, 5 inches; ♀, 5–6 inches.

_Hab._ Macassar, Menado (Celebes) (_Wall._).

39. PAPILIO BRAMA, Guérin.

_P. Brama_, Guér. Rev. Zool. 1840, p. 43, t. 1. f. 3, 4. _P. Palinurus_, De Haan, Verh. Nat. Gesch. pp. 5, 29.

_Hab._ Malacca, Sumatra (_Wall._).

40. PAPILIO DÆDALUS, Felder.

_P. Dædalus_, Feld. Lep. Nov. Philipp. p. 2.

_Hab._ Luzon (Philippine Islands).

41. PAPILIO BLUMEI, Boisduval. Tab. VI. fig. 4 (♂).

_P. Blumei_, Boisd. Sp. Gén. Lép. p. 206.

_Hab._ Menado (Celebes) (_Wall._). “Amboyna,” _Bd._, error of locality.

_Remark._—This very fine species comes nearest to the last, but is of much larger size, and is conspicuous by its brilliantly coloured tails.

42. PAPILIO ARJUNA, Horsfield.

_P. Arjuna_, Horsf. Cat. Lep. E. I. Comp. pl. 1. f. 14; Boisd. Sp. Gén. Lép. p. 209. _P. Arjuna_, var. _a._, Brit. Mus. Cat. of Papilionidæ, p. 17.

_Hab._ Java, Borneo, Sumatra (_Wall._).

The Bornean form differs from that of Java by its larger size, and on the under surface by the three middle lunules being formed of a violet line only, with scarcely a trace of red beneath it, and by the orange-red lunules both at the anal and outer angles being divided (not margined) by a violet line. The scales sprinkled at the base of the lower wings are white and blue, and are neither so dense nor do they extend so far as the yellowish scales of the Java specimens. In all these particulars the Sumatra specimens are somewhat intermediate, but approach most to those of Borneo. This is one of the examples which show the isolation of Java, notwithstanding its proximity to Sumatra.

f. _Memnon_ group.

(N.B. The _Protenor_ group of India is intermediate between this and the last group.)

43. PAPILIO MEMNON, Linnæus. Tab. I. figs. 1 (♂), 2, 3, 4 (♀s).

♀, 2nd dimorphic form, _P. Achates_, Cr. Pap. Ex. t. 243. A.

_Hab._ Java, Sumatra (_Wall._).

Local form _a_.—_Male_: border of posterior wings beneath narrow and of an ashy-blue colour.

_Female_: near _P. Anceus_, Cr., and _P. Laomedon_, Cr., but of an olive-ashy colour.

_Hab._ Borneo (_Wall._).

Local form _b_.—_Male_: band on under side of posterior wings ashy; the spots large, with reddish-orange lunules between the two series, and below the four outer ones.

_Hab._ Lombock (_Wall._).
