PAPILIO III., IV., V. 
these vary much, sometimes being rounded, sometimes lunular, or occasionally 
double-convex, or mostly mere streaks ; in some cases quite obsolete on the 
posterior half of the wing; on secondaries the margin is about one half broader, 
and often in very melanic individuals extends high up the disk on the posterior 
half of the wing, and is there much dusted' with yellow; there is a sub-marginal 
series of six large spots, usually lunular, of which the four inner are yellow, 
the others, one at each angle of the wing, deep orange, and smallest ; the ab¬ 
dominal margin above the angle excised, and there edged by an orange lunule, 
over which is a metallic-blue lunular cluster of scales on the black ground ; 
loose clusters of blue scales also on the two lower median interspaces ; some¬ 
times these are obsolete, and the sub-marginal lunules are reduced to streaks ; 
primaries usually have all the nervules black, and the sub-costal, especially, 
is heavily edged, but on secondaries the nervules are yellow, except the disco- 
cellular, which are covered by a black stripe; tail long, narrow, convex out¬ 
wardly, on the inner side spatulate ; at the end of second branch of median is a 
prominent dentation and there is another at anal angle, and in some cases 
these are so developed as to show a considerable approximation to the tails of 
Daunus ; fringes of primaries yellow in the emarginations, black at the ends of 
the nervules, about equally divided; on secondaries yellow predominates. 
Under side pale yellow; the nervules nearly all black; the sub-marginal 
spots of primaries enlarged, often confluent, and then forming a continuous 
stripe; anterior to this is a broad stripe of yellow scales which nearly covers the 
black ground ; secondaries have a similar stripe and on its anterior edge is a 
line of blue lunations; the yellow ground, next the marginal band, in the four or 
five posterior interspaces, more or less suffused with orange ; the sub-marginal 
lunules all more or less orange, this color being sometimes limited to a patch on 
the middle of each lunule, but the one at anal angle is usually wholly covered, 
as is that at the excision. 
Body above black ; a yellow stripe passes along the thorax from the head to 
the insertion of secondaries ; beneath, the thorax is yellow in front, alternately 
yellow and black on the sides in oblique stripes ; abdomen yellow with a lateral 
black line from the wings to the last segment, and with two ventral lines poste¬ 
riorly ; legs black with a yellow stripe in front; palpi yellow ; frontal hairs 
short, black; antennae and club black. 
Female. — Same size. 
Color deeper, decidedly ochraceous on primaries and along the abdominal 
margin of secondaries, the remainder of secondaries usually colored as in the 
male, but sometimes also ochraceous; the markings as in the male, but the 
bands are heavier; blue patches on the inner half of the marginal border of
