TRIFID.-E. 283 



shortened ; the rest of each segment is covered by a broad, 

 transverse, dark purple-brown band, extending to the 

 spiracles and hiding all other markings ; each white spiracle 

 is in a large black blotch connected with a narrower blackish- 

 brown transverse band on the ventral surface of each 

 segment ; head, entire second and half third segment, anal 

 tip and legs, and also a faint spiracular line visible only 

 on the anterior segments, are all of the olive-green ground 

 colour. 



When very young — just hatched — greenish tinged in front 

 with black ; head brown, usual raised dots distinct, each with 

 a stiff bristle. 



After a moult, full green with darker dorsal line and 

 whitish subspiracular stripe, the folds yellow. When half an 

 inch in length varieties begin to show themselves, some 

 remaining green with purplish-red dorsal line, while in 

 others the subspiracular stripe becomes edged along the 

 spiracles with purplish-pink. After this the dorsal purplish 

 lines begin to open and form the dorsal diamond, and the 

 pink subdorsal lines faintly appear. From this the more 

 brilliant colourings are gradually assumed — the back yellower 

 and the sides rose-pink, or brilliant grass-green with purple- 

 pink sides, the oblique marks on the front of each segment 

 black and forming a divided f^, the subdorsal line also marked 

 with black in front of each segment ; and the spiracular 

 yellow. From these the adult colourings are soon assumed.

 night. 



Pupa very cylindrical, tolerably even in bulk throughout, 

 though rather thicker in the middle, very smooth and 

 polished ; the tail ending in a small spike ; colour rich brown.
