30 W. Doherty — A List of the Butterflies of Engano. [No. 1, 
wardly incised. Hindwing , rich ochreous yellow, (without any orange 
tinge) from the first subcostal vein to the hind margin ; the outer border 
rather widely black (but not subanally), the outer part of the veins, 
except the submedian and especially the subcostals and radial, also black, 
bordered with diffused scales. Below, the white area is reduced on the 
forewing, the upper submarginal spots united in a large triangular 
bright yellow mass, only the lower two white, that above the upper 
median vein obsolescent. Hindwing lemon yellow, ochreous yellow on 
the extreme anal margin, with greenish areas above and below the cell, 
especially around the subcostal veins ; the dark brown border very wide, 
attaining the cell, enclosing six yellow spots, all large except the fourth 
which is obsolescent, the first three more or less united. 
The absence of all orange on the wings, the submarginal band of 
the forewing, the veins outlined with black on both wings, the very 
broad marginal dark band of the hindwing below, and the large extent 
of the yellow area, tinged with greenish below, easily distinguish this 
peculiar species from Huphina lea and judith. 
Only one male, taken at Bua Bua. 
Family Papilionmd.e. 
47. Ornithoptera nereis, n. sp. A local form of 0. pompeius, 
Cramer. Male. Above, black, the cell immaculate, the veins of the disc 
black, bordered with rather conspicuous whitish rays. Hindwing golden 
yellow, bordered with a deeply scalloped black band, which is only about 
-Jj of an inch wide at the ends of the veins, the base black above the 
middle of the costal space, including the root of the cell ; two (in one 
specimen five) black discal spots subanally in the gold. Below, the 
white streaks near the veins are more continuous, and the end of the 
cell is slightly touched with whitish; a little red at the base of the wings. 
Female, with the outer third of the cell entire]’ dull whitish, the 
whitish streaks between the veins coalescing, and extending nearly to 
the outer margins, the black rays in the middle of the spaces not nearly 
reaching the cell ; hiudwing very dull golden, the border wide, the 
discal spots coalescing widely with each other and with the outer black 
band, so as to enclose small yellowish lanceolate spots in pairs divided 
by the veins. Below, the hiudwing is dull pale whitish-yellow, without 
any golden tint ; this area extends only to the upper subcostal vein and 
occupies two-tliirds of the cell. Several males and two females were 
taken, but one of the latter was unluckily destroyed, and the other is 
worn. 
This species seems nearest the South Indian Ornithoptera minos,
