Mr. A. R. Wallace on the Genus Iphias. 5 
The head and thorax in both ¢g and 9 are brown-tinged; the 
abdomen of the colour of the wings respectively. 
The under surface has the characteristic markings of the genus ; 
but in the 9 they are more dense, while in the ¢ the lower wings 
have only scattered spots and striz. 
I first found the female of this interesting species flying among 
dense thickets in the island of Bouru, and was completely puzzled by 
its appearance, till I one day caught a glimpse of the under side of 
its wings, when I knew it must be an Jphias. I afterwards obtained 
a few males; but it was never abundant. 
Iphias sulphurea. 
é. I. supra pallide fulvo-sulphurea ; alis anticis apice late nigro, macu- 
laque magna apicali fulvo-rubra ; margine costali grisea. Subtus fulva 
fusco irrorata ; alis anticis apice obscuriore, basi flava immaculata. 
@. Alis anticis macula rubra apicali parva; posticis margine posteriore 
intus dentato maculisque submarginalibus nigvis. 
Exp. al. 4°5. 
Hab. Batchian, Gilolo (Ins. Molucc.). 
The male resembles at first sight the Borneo var. of Jeucippe, but 
is entirely of a pale lemon-yellow instead of white. The black 
apical portion is smaller, only touching the end of the discoidal cell ; 
and the red patch is very much smaller, containing only three tri- 
angular black spots, the two upper of which join the outer, and the 
lower the inner portion of the black border. The lower wings have 
the posterior margin tinged of a deeper yellow. 
The female generally resembles the male, but the black extends a 
little further on the upper wings, and on the lower forms a broad 
band, dentated within along the posterior margin. Within this is 
a row of six subtriangular spots, as in the females of the other 
species. Beneath, the lower wings and the apical portion of the 
upper are rich fulvous yellow, thickly covered with dusky irrorations, 
which are darker on the inner margin of the lower and the apex 
of the upper. The basal portion of the upper is pale sulphur- 
yellow. 
This fine species occurred in Batchian (a single male specimen, 
taken on the margin of a stream), and in Morty Island, to the N. 
of Gilolo, whence my collector, Mr. Allen, has sent me both sexes.
