PAPILIO III., IV., V. 



sub-ovoid, with one liair at toji 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, 

 bearino- 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 r5 to 12 three 

 each in equilateral triangle, each point bearing one hair ; head ob-ovoid, brown. 

 (Figs, c, (?, &, XIII. ; h. 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 

 saddl6-.shaped, very much as before, white ; on front of 2 a compressed cross- 

 ridge, with 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 

 spot 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 ; C, 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", 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". 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 each sub- 

 dorsiil a black bar ; on 5 are two knobs in front, as large as the outer pair on 4,
