white between the veins; the usual sulphur-yellow costal 
streak: body black; abdomen greenish. Primaries below 
ash-grey, the black streaks and veins narrower than above : 
secondaries greenish black; a decreasing submarginal series 
of four orange lunules from apex to lower radial interspace ; 
a few scales in the second median interspace, a large crescent 
in the first median interspace, and a large irregular patch 
enclosing a black spot, sprinkled in front with white scales, 
and bordered with white on the margin at anal angle: body 
below black. Expanse of wings 118 millim. 
6. Tateyama Bay, entrance to Gulf of Yedo. 
@. Much larger than the male. Primaries above pale 
brown, the veins and streaks blackish brown, diffused : secon- 
daries with the basal half smoky brown, with a central nebula 
of bluish scales; external half blackish brown ; a few orange 
scales on the second median interspace, a crescent on the first 
median interspace, and a large patch enclosing a round black 
spot and sprinkled in front with white scales, at anal angle: 
body smoky brown ; head, as usual, black, dotted with white. 
Primaries below whiter than in the male, the cell slightly 
tinted with sulphur-yellow: secondaries dark chocolate-brown, 
the cell dark green; a continuous submarginal series of 
orange crescents, the first, second, and sixth large, the first 
sprinkled with pearly scales; anal orange patch larger than 
in the male, its upper portion extending inwards to beyond 
the second median branch, and more distinctly sprinkled with 
pearly scales: body below smoky brown, a whitish line down 
each side of the venter. Expanse of wings 136 millim.

The male from Whitely’s collection is a little smaller than 
that obtained by Lieut. Carpenter, and agrees with its female 
in having a complete submarginal series of orange lunules on 
the under surface. The species stands nearest to P. demetrius, 
from which it differs in its smaller size, not much exceeding 
that of P. macilentus, the paler and not greenish colour of the 
primaries, the narrower tails of the male and the shorter tails 
of the female, the larger reddish-orange borders to the anal 
spot on the male, and the more uniform blackish colour of the 
secondaries below ; from P. macilentus it differs in its supe- 
rior size, broader wings, and shorter tails, and from P. tract?- 
pennis in its shorter wings and tails. 
In identifying this group of Papiliones it must always be 
borne in mind that the males have longer or narrower tails 
to the secondaries than the females, and consequently without 
due care the examples of the latter sex are likely to be con- 
founded.
