314 SPHINGID^]. 



<$. Tenth tergite as in dohertyi, tergite a little broader. 

 Olasper with numerous friction-scales ; harpe slender, nearly 

 as in automedon. Penis-sheath : right process projecting 

 as in dohertyi, but broader at end and more heavily dentate ; 

 left process as long as in malayana, but broader. 



Hab. E. Himalayas and Burma, extending to Malaya and 

 the Philippines. We have bred the subspecies in the Khasi 

 Hills, where eggs and larvae are common during the monsoon. 



Egg. — Yellowish-green, the bright orange of the young larva 

 showing through before hatching. 



Larva :■ — 



1st instar. Body long and thin, horn straight, of medium 

 length ; head and body orange, horn black. 2nd instar. 

 Surface smooth and shining ; head and body translucent pale 

 green, horn black. 3rd and 4th instars. Body long and thin, 

 segment 5 tumid ; horn long, straight ; surface of head and 

 body smooth and dull, horn shining ; head and body pale 

 yellowish -green ; an oval, longitudinal, black ocellus on 5 ; 

 horn black above, pale green on sides and centre. 



5th instar. Shape as in others of the genus ; horn thick at 

 base, tapering sharply to a blunt point, basal half at right 

 angles to dorsum of larva, distal half bent sharply downwards. 

 Body smooth and dull, excepting the ocellus and the band 

 above it, which are shining as though enamelled, and the 

 horn, which is shining and covered with small tubercles. 



Coloration. — Head bright green. Body pale yellowish- 

 green ; segments 4 and 5 bright green on dorsum, marked with 

 longitudinal white dashes ; a dark green, narrow, dorsal stripe 

 on 2 to 5, with a pinkish stripe on each side of it on 5 ; an oval 

 longitudinal ocellus on 5, black above, reddish-brown below, 

 the reddish- brown portion outlined by a narrow pale band, 

 the whole edged by a narrow blackish line ; above the ocellus, 

 and touching it, a broad white band with a bright red quadrate 

 spot in the centre of it ; a broad, brown subdorsal stripe 

 starts from the front margin of 2, runs across 3 and 4, below the 

 ocellus on 5, then turns up to dorsum along hind edge of 

 5, this stripe being edged below by a narrow pale stripe ; 

 a brown spiracular stripe runs from the spiracle on 6 to the 

 hind margin of 11, this stripe narrow at the spiracles, wider 

 between them ; 13 and anal flap brown, with a broad, green, 

 dorsal stripe from base of horn to tip of flap. Segments 

 6 to 12 are sometimes immaculate except for the spiracular 

 band, or marked with irregular brown patches. When bred 

 in the dark the brown colour may spread over the whole of 

 these segments. Horn orange ; true legs pink, proiegs green. 

 Spiracles black edged broadly with white. Length 95 mm. ; 

 breadth 8 mm. ; horn 5 mm.
