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.—This approaches the next species. Subspecies à and c I consider to be 
really as distinct as many universally received species, differing 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.

Hab. Borneo (Wall.), Java (Van der Hoeven). 
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.

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
