438 SPHINGIDiE. 



eggs we were unable to distinguish any difference between 

 the larvae from these and larvae of c. clotho with an ocellus on 

 segment 5 only. 



Pupa. — Very similar to that of c. clotho, but differs in the 

 following respects : tongue-sheath not more prominent 

 ventrad than frontad ; mid-leg not so long ; front bevel of 

 segment 9 with about twelve ante-spiracular ridges more or 

 less parallel but anastomosing in places, 10 and 11 with less 

 prominent ridges ; spiracle of 2 in a shallower depression, and 

 the palpal depression also shallower ; the depression under 

 base of cremaster much deeper ; wing-case not so dark in 

 colour, but with black streaks along R 1 and R 2 , and black dots 

 on bases of veins and along costa. 



Habits. — Food-plant : VitislAnn., family Ampelideae. Habits 

 similar to those of c. clotho.

Imaqo. — <£§. Head and body drab, antenna, front of head 

 and sides of thorax paler ; abdomen with no black side- 

 patches and no stripes. Fore wing drab with six discal lines, 

 the first nearly always dilated near apex of cell ; a black 

 basal patch at inner margin more or less vestigial ; a black 

 speck at end of cell. Hind wing smoky-black, paler towards 

 anal angle. Underside buff or vinaceous-buff. Cavity at 

 end of first segment of palpus (fig. 110 D, E) partly concealed 

 by irregular scaling. External row of spines of first pro tarsal 

 segment double, at least at base. Expanse : $ 64-86 mm., $ 

 78-86 mm. 



$. Tenth abdominal tergite long and slender ; apex of 

 sternite rounded-truncate. Gasper with a patch of about 

 ten enlarged scales, in two or three oblique rows, nearer 

 apex than base; harpe (fig. 110 F) prolonged into a free, 

 straight, obtuse, somewhat tapering process. Tip of penis- 

 sheath (fig. 110 G) acute, the teeth mostly three -pointed. 



Hab. E. Himalayas, S. India, Ceylon, Burma and the 

 Andaman Islands to Malaya and the Philippines. We have 

 bred it in S. India, where it is very common in the Kanara 

 District, and may be found at all times of the year.
