PAPILIO III., IV., V. 
sub-ovoid, with one hair at top and six about the sides, these last rising from 
little spurs, each hair ending in a knob; on dorsum of each segment, from 2 to 
13 inclusive, are two points, with one short hair to each; and there are two sub¬ 
dorsal rows of tubercles, those on 3, 4, 11, 12, 13, in shape as on 2, but small 
and low, each with a few clubbed hairs; from 5 to 10, minute, without hairs; 
on either side, a row of tubercles from 3 to 12, with a point in same line on 2, 
bearing a single hair; on 3 and 4 these are small, and show three and two hairs 
respectively, the remainder mere points without hairs; below the spiracles a row 
of points, on 2 one, on 3 and 4 three each in horizontal line, on 5 to 12 three 
each in equilateral triangle, each point bearing one hair; head ob-ovoid, brown. 
(Figs, c, c 2 , c 3 , XIII.; b, III.; a, IV. ; the last two representing the larva near the 
end of the stage.) To first moult about four days. 
After first moult: length, at twelve hours, .25 inch ; same shape; color, black- 
brown ; a black medio-dorsal line, expanding a little on 3 and 4 ; the patch 
saddle-shaped, very much as before, white; on front of 2 a compressed cross¬ 
ridge, w T ith tubercles as before, more conical; 13 has a pair of similar tubercles, 
also on a ridge, 12 a smaller pair, and on 11 and 10 each two low cones; on 3, 
4, 5, are two sub-dorsal rows of low, round, glossy, brown knobs; between these 
on 3 are two similar knobs, but minute, and the four are in line ; in some exam¬ 
ples there is an additional small knob high on the side, the six being in line; on 
4 the dorsals are in advance of the sub-dorsals, and there are always two outside, 
six in all; on this segment, the two outer knobs on either side each have a lilac 
sjoot on the dorsal side ; 5 has but four knobs, the dorsals much in advance, and 
these last have each a lilac spot on inner side ; 6, 7, 8, 9 have no knobs or spots, 
but the points on 10 and 11 have each a lilac spot; head rounded, broadest be¬ 
low, the top depressed; color, dark brown. (Figs, e, e 2 , XIII.) Later in the 
stage the surface is more or less mottled dark and light brown, with a greenish 
tint in some examples; the white of the patch changes to pale yellow. (Figs, 
c, c 2 , III.) Duration of this stage about five days. 
After second moult: length at twelve hours, .5 inch; much the same shape; 
color, black-brown, with shades of lighter; on back of 2, 3, 4, a black patch to 
each ; the saddle yellow-white, and extending low down the sides; the last two 
segments mottled brown and yellowish ; the ridge on 2 as before; at either end 
a small cone, the top of which shows several spurs, each with short hair; on 13 
similar cones on ridge, on 12 a smaller pair; on 3 are six knobs in line, the 
dorsal pair small, the outer pair a little larger, the sub-dorsals large ; on 4 are 
six, the dorsals large, the rest a little smaller and equal, and on the inner side of 
each of these last is a lilac spot; also on the anterior outer side of eacli sub¬ 
dorsal a black bar; on 5 are two knobs in front, as large as the outer pair on 4,
