especially the one on joint 2. Thoracic feet of joint 2 black, 

 the others white. Segments annulate behind, pile small, obso- 

 lescent, tubercles whitish. Very transparent, the blood watery, 

 the food in the stomach dark green. Stomach, dorsal vessel, 

 tracheae of both skin and stomach, sex glands (the % elliptical, 

 subdorsal, situated in joint g, the $ a slender oblique cord in 

 joint 10) and the internal organs in general all plainly visible. 

 A diffuse white subdorsal stripe of pigment on the skin; subven- 

 tral fold narrowly whitish. A nearly white patch on each side 

 ventrally of joints 1 1-12. Spiracle of joint 12 a little higher up 

 than the rest, with short, densely radiating tracheae ; edge of 

 joint 13 pilose, pale. The larva lives in one or more leaves 

 united by silk. 



Pupa.-^ Formed in the resting place of the larva, held by a 

 transverse loop and a band of silk for the cremaster. The cre- 

 mastral band is attached at one end to the leaf, at the other to a 

 transverse thread. Pupa slender, cylindrical, a little thickest 

 through mesothorax, last two segments tapering. Eyes large, 

 prominent; a long, thick horn arising between them, recurved a 

 little at the tip. Cases reaching the third abdominal segment, a 

 long slender tongue-case reaching back 21 mm., or 5 mm. beyond 

 the end of the cremaster. Legs of segments 4-6 represented by 

 little patches of corneous scales. Three moveable incisures. Cre- 

 master long, hollowed below at base with many terminal hooks. 

 Pale green with white bloom, a curved blackish bar between the 

 eyes ; horn dark red ; a set of black dots on abdomen in the 

 normal position of tubercles i, ii and v of larva, a pair of dots 

 on prothorax and one on metathorax subdorsally. Exactly, the 

 abdominal black dots are thus: seg. 1, tubercle ii; segs. 2 and 3, 

 tubercles i and ii; segs. 4-6, tubercles i, ii and v; seg. 7, tuber- 

 cles i and ii; seg. 8, tubercle ii, this spiracle obsolete, represented 

 by a scar ; no tubercles behind seg. 8. Skin finely wrinkled, 

 shagreened. Dimensions 40 x 7.5 mm. ; length of horn 3 mm.
