Inhabits Melville Island, on the north coast of New Holland. In 
the Collection of the Rev. F. W. Hope, and the British Museum. 
This species is most nearly allied to Papilio Pammon, from 
which it however differs in its considerably broader wings, the 
fore pair of which are further distinguished by the fascia of large 
white, or pale buff spots, separated from each other by the dark 
veins of the wings and by the analogous fascia in the hind wings 
which runs more regularly parallel with the apical margin of these 
wings, whereas in P. Pammon, the anterior edge of this row of 
spots forms nearly a straight line. The disc of the wings, both 
above and below, is also much less glossed with the minute fulvous 
scales than in P. Pammon. 
The male has the fascia on the fore-wings much more strongly 
defined than the female, and of a more buff colour. In the hind 
wings of this sex above, the fascia is followed next the anal angle 
by a very slender blue lunule, and there are some blue scales 
forming very nearly obsolete patches behind the next two inner 
pale spots; on the under side, however, these blue patches are of 
large size, and distinct behind each of the large cream-coloured 
spots forming the fascia, the one next the anal angle having a 
scarcely visible orange lunule behind it. On this side also between 
the blue patches and the white incisions is a row of dirty buff spots,
