segments then increasing in diameter to 7 ; horn as above ;:

 tubercles as before. Colour of the head dark green dotted 

 with white ; two narrow, whitish stripes down the face 

 and one down each cheek ; the processes brown, and a brown 

 dorsal stripe running from their tips to the nape ; body green 

 with yellow tubercles ; oblique stripes on 5 to 11 formed of 

 larger yellow tubercles ; horn as before. Some specimens 

 have irregular reddish blotches and oblique stripes. 4£h 

 instar. Little change. 



5th instar. Head triangular, vertex rounded, with a short 

 blunt process on the apex of each lobe, length greater than the 

 diameter of segments 2 and 3. Surface of head smooth and 

 shining, covered with small, low, evenly- spaced tubercles- 

 Body increasing gradually and evenly from 2 to 8, and then 

 decreasing slightly to 12. Horn straight, thick at base and 

 tapering evenly to a blunt point. Surface of body dull, with 

 a transverse row of low tubercles on each secondary ring ; 

 a dor so- lateral line of large pointed tubercles from segment 2 to 

 base of horn ; seven oblique stripes also formed of pointed 

 tubercles ; horn covered with smaller tubercles. 



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

 row white stripe on each side of dorsal line from vertex to 

 apex of clypeus ; a broad white stripe down each side, separating 

 the face from the cheek ; the processes pale yellow ; a white 

 subdorsal stripe running from each process to the nape and then 

 joining the subdorsal line of tubercles on the body. Body 

 bright bluish-green, paler below the spiracles, the rows of 

 tubercles yellow ; the subdorsal dor so -lateral line of tubercles 

 and those forming the oblique stripes yellow ; a narrow supra - 

 spiracular stripe on 2 to 4, meeting the oblique stripe on 5 at 

 its lower end, also yellow. Horn green with the tubercles 

 paler green ; legs reddish with a black ring on each segment ; 

 prolegs and claspers green. 



In another form of the larva the transverse rows of tubercles 

 white, those forming the subdorsal and oblique stripe mauve, 

 and the supraspiracular stripe also mauve. 



In a third form the head-processes and a dorsal stripe 

 down back of head brown ; dorso-lateral line of tubercles 

 and supraspiracular stripe whitish, with a broad, irregular, 

 purple-brown band between them and below them on to venter ;
