488 sphingid^:. 



5th instar. Very similar to that of C. I. lineosa, but much 

 paler. Head dull and smooth. Body dull and smooth ; ocellus 

 shining as though enamelled ; segment 5 swollen and both 



4 and 5 somewhat dilated ventro -laterally ; horn of medium 

 length, slightly flattened laterally, tapering slightly to a blunt 

 point, down-curved; surface shining and covered with bluntly 

 pointed tubercles. 



Coloration. — Head brown dotted with paler brown. Body : 

 dorsal area coloured like the head, lateral area pinkish ; 

 a narrow black dorsal stripe on 2 to 5 ; a broader dor so -lateral 

 stripe from 2 to base of horn, pale brown on anterior segments, 

 nearly white on posterior segments, broken by the ocellus on 



5 and edged above with dark brown ; ocellus with pupil deep 

 indigo-blue dotted with yellow in the posterior half, edged 

 narrowly with yellow and still more narrowly with black ; 

 a round whitish subdorsal spot in the posterior half of 6 to 11 ; 

 oblique stripes on 5 to 10 pale pink edged above with dark 

 brown which shades into the body-colour, these stripes reaching 

 the dorso-lateral stripe, that on 10 running across 11 and 12 

 to base of horn. Horn brown ; legs reddish. Spiracles pink 

 with a brown suffusion on each side of the slit. Length 

 85 mm. ; breadth 11 mm. ; horn 8 mm. 



Pupa. — Tongue-sheath projecting considerably frontad, but 

 not so much as in C. lineosa ; antenna slightly longer than 

 fore leg, which reaches to beyond middle of wing-case, mid-leg 

 to three-quarters length of wing-case. Surface dull, head 

 and thorax slightly sha,greened ; wing-case with lines of pointed 

 tubercles along the veins. Cremaster nearly equilaterally 

 triangular, tip squarely truncate ; a long thin spine at each 

 lateral angle of the truncation and a short spine mid-way 

 between them, all straight and pointing directly backwards ; 

 from the base of each of the longer spines a spine of equal 

 length, bifid at the tip, projects directly outwards ; a dorso- 

 lateral spine with three or four points near base ; all the spines 

 polished and shining ; upperside of cremaster rugose, under- 

 side deeply hollowed. The pupse obtained in the Khasi 

 Hills were similar to the above except for the cremaster, in 

 which the long terminal spines are curved inwards instead of 

 being straight, and the dorso-lateral spine is replaced by a simple 

 steel-blue pointed spine. The cremaster of the pupse obtained 

 by Mell in S. China agrees with that of those from the Khasi 

 Hills. The difference may be individual or may point to the 

 existence of two subspecies. Head, thorax and wing-case 

 dark brown ; a broad dorsal stripe paler brown ; tubercles on 

 wing-case black ; abdomen with a dark brown dorsal stripe, 

 and a broader degraded ochreous stripe on each side of it, 

 la teral area dark grey with short whitish stripes ; spiracles 

 bl ack, those on segments 6 to 12 lying on a larger black patch ;
