Larva : — 



1st instar. Head round, body cylindrical, horn long, straight; 

 colour pale green ; head 1-5 mm. long by 1-1 mm. broad. 

 2nd instar. Head triangular, with a long tuberculate process 

 rising from apex of each lobe, the two processes closely 

 appressed ; body cylindrical ; horn of medium length, straight, 

 ending in a conical point ; colour of head and body green ; 

 a subdorsal line of multi-pointed orange tubercles from 

 front margin of segment 2 to base of horn ; seven oblique 

 stripes formed of orange tubercles ; the spiracle of segment 5 

 surrounded by an ocellus-like marking, dark green edged with 

 crimson ; head 5 mm. long by 1-8 mm. broad. 3rd instar. 

 Little change ; a transverse row of small orange tubercles 

 on each secondary ring ; head 9-0 mm. high by 3-5 mm. 

 broad. 



4th instar. Head very elongate-triangular in shape, with 

 a blunt-ended process rising from the apex of each lobe, the 

 two processes so closely appressed that the}^ appear to be an 

 upward prolongation of the head. The anterior secondary 

 ring -of segment 2 of greater diameter than base of head, 

 and the secondary rings decreasing in diameter to the middle 

 of the segment ; from the middle of 2 the body increasing in 

 diameter gradually to 10, then decreasing gradually. Surface 

 of head moderately shining, set sparsely with small tubercles. 

 Horn straight, of medium length, tapering evenly to a blunt 

 j)oint, held slightly above the horizontal ; anal flap and 

 claspers heavy. Body dull ; a transverse row of small 

 tubercles along each secondary ring ; a larger tubercle close 

 to the dorsal line on each secondary ring, forming a subdorsal 

 line of tubercles from front margin of segment 2 to base of 

 horn, these tubercles increasing in size posteriorly ; seven 

 oblique stripes formed of larger tubercles, that on 5 formed 

 of larger tubercles than the rest ; scattered tubercles on horn, 

 anal flap and claspers. 



Coloration. — Head pale bluish-green, the tubercles white ; 

 -a narrow green stripe runs from the apex of each process to 

 base of antenna, and from apex of each process to nape, 

 where it joins the dorsal stripe of the body. Body : segments 2 

 to 4 pale bluish-green, rest of body green ; a broad dark green 

 dorsal stripe from front margin of 2 to base of horn ; an 

 indistinct whitish stripe on each side of the dorsal stripe, the 

 tubercles on this pale stripe orange ; an indistinct whitish 

 dorso-lateral stripe on 2 to 4 ; the oblique stripe on 5 pale 

 yellow, the remaining oblique stripes whitish and less broad, 

 the tubercles on the stripes orange. Horn pale yellow with 

 orange tubercles ; the transverse rows of tubercles and 

 those on anal flap and claspers orange. Spiracles white 

 edged with black ; that on segment 5 broader than the rest,
