4 Mr. A. R. Wallace on the Genus Iphias. 
species. But the allied forms here described break down the 
boundary-lines that separate them, and others probably yet remain 
to be discovered, so that it seems more convenient to consider them 
as local races. The best-known form of the species, that from India 
and Java, has characters which are nearly intermediate between the 
others, and may thus be considered as the typical race. All the 
varieties have very nearly the same creamy-white ground-colour of 
the wings and the same peculiarly irrorated under surface.

This fine species does not seem to vary, and is the richest in 
colour of the genus. It is by no means abundant in Amboyna, 
where it is only to be met with in the forest-clad mountains of the 
interior. In Ceram it is still more scarce.

The male somewhat resembles J. leucippe, but is of a rather paler 
yellow, which colour extends on the upper wings to the median 
nervure and beyond its 8rd branch. The red of the upper wings is 
nearly the same in colour as in that species, but much less in extent, 
the outer margin and apex being broadly black. The submarginal 
row of black spots is also rather larger and less clearly defined. 
The female is remarkable by the entire absence of any yellow or 
red colour. The lower wings are of a semitransparent pearly white, 
which extends on to the upper as far as the yellow does in the ¢. 
The rest of the upper wings, the outer margin of the lower, and a 
submarginal row of six spots are dusky black.
