106 SPHINGIDJE. 



Hab. Throughout the Indian Region. China, Malaya and 

 the Philippines. We have bred it in S. India, where larvae 

 were obtained in wooded hills. 



Egg. — A perfect ovoid ; surface smooth and shining ; colour 

 yellow. Length 2-6 mm. ; breadth 2-15 mm. 



Larva : — 



1st and 2nd instars not recorded. 3rd instar. Head trian- 

 gular, a spiniform process rising from vertex of each lobe, the 

 two processes appressed into a long cone-shaped extension 

 two-thirds the length of the head. Surface of head smooth, 

 covered sparsely with small tubercles ; the processes shining 

 and set with pointed tubercles. Body nearly cylindrical, 

 tapering slightly from segment 5 frontad ; surface smooth, 

 with a dorso-lateral line of pointed tubercles on 2 to 11 ; horn 

 very long, thin, sharply pointed, curved gently upwards : 

 surface shining and covered with small tubercles. Colour 

 of head glaucous-green, with a yellow cheek-stripe from 

 vertex to base of antenna and from vertex to nape; 

 body white above the longitudinal line of tubercles, with 

 a broad green dorsal stripe, grass -green below the line of tu- 

 bercles ; the tubercles yellow on 2 to 4 and then white ; yellow 

 oblique stripes on 5 to 11 : horn dark brown dorsally. yellowish 

 ventrally ; true legs brown, prolegs and claspers green, anal 

 flap and claspers edged with yellow. 1th instar not 

 recorded. 



5th instar. Head triangular, higher than broad, vertex 

 slightly truncate, without apical processes : clypeus one-half 

 length of head, sunken, apex rounded, basal angles tumid : 

 no false clypeus ; ligula trapeze-shaped, widening frontad. 

 the sinus wide and deep. Surface of head shining, very 

 shallowly corrugate and set with sparse, irregularly- spaced, 

 small, circular tubercles. Body tapering slightly from seg- 

 ment 7 frontad. flattened laterally from segment 8 to 12 ; 

 surface dull. Horn long, thick at base, tapering evenly to a 

 sharp point, basal half horizontal, distal half gently up-curved. 

 A transverse row of small, sharply pointed, conical tubercles 

 on each secondare' ring : a dorso-lateral line of large tubercles 

 on segments 2 to 11, as in the 3rd instar : oblique stripe on 

 segment 11 set with large tubercles. 



Coloration. — Head glaucous-green ; a dorsal stripe from 

 vertex to apex of clypeus, then dividing and running down 

 sides of clypeus : a stripe separating face from cheek ; a sub- 

 dorsal stripe from vertex to nape, where it joins the subdorsal 

 line of tubercles on the body ; all these stripes narrow and 

 yellow : labrum glassy-greenish : ligula greenish : basal 

 segment of antenna yellowish -green, other segments pale 

 reddish -brown : mandible violet, tip brown. Body grass- 

 green, dorsum glaucous- white : tubercles and obliqiie stripes
