OF THE MALAYAN REGION. 65 



Beneath, the greenish white band continues on to the lower wings, but gradually 

 fades away after reaching the cell. Expanse of wings 4^ inches, 

 Hab. Waigiou, Aru Island [Wall.). 



Remarks. '—Thh approaches the next species. Subspecies b and c I consider to be 

 really as distinct as many universally received species, difiPering in form and in several 

 points of coloration. As, however, it is probable that there are forms in other islands 

 which may present intermediate characters, I prefer retaining the whole under the old 

 specific name,

Remarks. — This remarkable species has been placed by Boisduval in a group by itself. 

 It, however, agrees very closely in habits and structure with this group, and can hardly, 

 I think, be separated, though very abnormal in colouring, P. Evan, Db., is a closely allied 

 species from India ; and P. Gyas, Westw., from the same country, is also nearly related, 

 though it has been hitherto placed in another section of the genus. 



110. Papilio Sarpedox, Linnaeus.

Hab. Borneo, Sumatra (typical), New Guinea, Aru Is. (darker), Java (broader band) (Wall.). 



Local form a {Moluccensis, Cram. Pap. Ex. t, 122. f. D, E). — Black, with the bands and 

 spots rich blue. 

 Hab. Ceram, Batchian, Gilolo, Bouru {Wall.). (The Ceylon form closely resembles this.) 



111. Papilio Miletus, n. s. Tab. VII. fig. 2 (c?). 



Wings larger and more falcate than in P. Sarpedon, costal margin abruptly curved 

 near the base of the wing. 



Above, black ; macular band rich blue, very narrow, the spots on the upper wings all 

 more or less rounded and separated by thick black bands ; the marginal lunules large and 

 angularly bent. 



Beneath, the upper wings have a row of four pearly-white lunules from the outer 

 angle ; and there is one of the same colour at the outer angle of the lower wings, which
