56 sphingid^. 



similar ; underside of abdomen yellow, the distal five or six 

 segments blackish, leaving only a narrow, yellow, terminal 

 band to these segments. Antenna black, tip shortly yellow ; 

 legs black banded with yellow. Expanse 102-132 mm. 



(J. Armature of harpe (fig. 9 B) represented by two parallel 

 hooks, sinus between them rounded (in dorsal view). 



2. Vaginal aperture provided proximally with a transverse 

 ridge or flap, which is rounded laterally and shallowly sinuate 

 mesially. 



Hab. Throughout India, Ceylon and Burma. Also occurs 

 in China and eastwards to the Southern Moluccas. Common, 

 especially in hills and forest areas. 



Larva : — 



1st instar. Head and body pale yellow ; horn black, long, 

 straight, bifid. 



In the succeeding instars, head and body green, horn 

 green ; pale yellow oblique stripes develop, and pointed 

 tubercles which disappear in the fourth instar. A grey 

 and a canary-yellow as well as the green form may appear 

 in the third instar. 



5th instar. Head with shining surface, covered sparsely 

 with small, glassy tubercles, surrounded by groups of minute 

 tubercles ; broadly semi-elliptical, vertex flattened ; true clypeus 

 about one-third length of head, basal angles broadly rounded ; 

 apex of false clypeus rounded, reaching to one-half length of 

 head ; labrum broader than clypeus, narrowing frontad 

 to half the breadth of its base ; ligula kidney- shaped ; eyes 

 1 to 4 equidistant, in a gentle curve, 6 in line with 3 and 4 

 and twice as far from 4 as 4 is from 3 ; 5 at right angles to 

 the line 3, 4, 6, and about as far from 4 as 4 is from 6. Body 

 tapering slightly frontad from segment 7 ; each secondary 

 ring on 2 to 4 raised into a sharp ridge in the dorsal area, 

 the anterior ring of 3 higher than the rest. Surface dull and 

 smooth. Horn long, stout at base, tapering first gently, 

 then more strongly, to a sharp point, basal half curved down- 

 wards and distal half strongly upwards, sometimes forming 

 a complete ring ; surface shining and thickly set with large, 

 conical tubercles. 



Coloration. — A grey, a green and a yellow form, the grey 

 being the most common. 



Grey form : Head black or dark brown ; a paler brown 

 or white subdorsal stripe, and a similar stripe separating 

 the face from the cheek, the two stripes meeting near vertex ; 

 a white dorsal stripe from vertex to apex of clypeus, thence 

 running down each side of clypeus ; clypeus white with black 

 edges ; labrum and ligula whitish ; antennal basal segment 

 white with the outer sides black, second segment brown, 

 end segment pale pink ; mandible shining black. Body 

 grey or greenish-grey, each hair rising from a dusky- coloured
