 stripe, starting at the middle of the hind margin of 7 and 

 running to base of horn ; broad, white, and sharply denned 

 on 12, edged narrowly above by dark green or violet ;. 

 very obscure yellowish-green oblique stripes on 4 and 5 ; 

 a broad, white, sharply denned oblique stripe, finely veined

 chestnut ; legs white with a dark brown streak down the outer 

 face of each segment ; prolegs with base and shank green, 

 ankle green tinged with violet, feet violet. Spiracles small,

 ground-colour is replaced by brown, with markings as in the 

 green form. Length 70 mm. ; breadth 12 mm. ; horn 7 mm. 



Pupa. — Slender in build ; tongue-sheath projecting much 

 frontad, the ventral surface of sheath concave basad ; antenna 

 about half length of wing-case, fore leg slightly shorter ; 

 a narrow coxal piece. Surface dull, superficially, transversely 

 wrinkled on head, thorax and wing-case, sparsely pitted on 

 abdomen ; short, irregular ante-spiracular ridges on segment 9. 

 Spiracle of 2 a narrow slit nearly covered by a narrow, oblong, 

 transverse lobe projecting from the front margin of 3 ; remain- 

 ing spiracles broadly oval, surface slightly convex, central 

 slit with raised edges. Cremaster nearly oblong, with a small, 

 conical tooth, directed outwards, at each lateral angle of the 

 truncate tip ; dorsal surface convex and pitted ; ventral 

 surface with a deep median channel. Colour bone-yellow, 

 tongue-sheath pinkish, abdomen suffused with pale violet- 

 brown ; a dark brown dorsal stripe on thorax becoming broad 

 and greenish on abdomen ; venter pale pinkish-yellow, with

Habits. — Eggs laid singly on the underside of a leaf or 

 on a thorn of the food-plant, Carissa carandas Linn., and other 

 plants of the genus, family Apocynacese. In the resting position 

 the larva raises the head and anterior segments at a sharp 

 angle with the rest of the body. The dorsum turns brown 

 before pupation, which takes place in a rough cocoon on the 

 surface of the ground. The moth rests with the wings held 

 horizontal and the tip of the abdomen slightly upturned. 

 The flight is rapid, and the moth comes to flowers before 

 dark, being also attracted by light.
