Pupa. — Very similar to that of bus iris. Cremaster broadly 

 triangular, dorsal surface rounded, ventral surface deeply, 

 longitudinally concave, ending in a stout shaft which branches 

 near base, each branch ending in two hooks ; two shorter 

 shafts, each with a single hook, on each side of base of central 

 shaft. Length 50 mm. ; breadth 10 mm. 



Habits. — Food-plants : Colocasia antiquorum Schott., Amor- 

 pliophallus Linn., Caladium Linn., Aris8em,a curvatum Kunth., 

 and other plants of the family Aroidese. The habits of the larva 

 are similar to those of metallica, but we have not seen this 

 larva adopt the peculiar attitude of defence described, under 

 that species. It merely retracts the head and anterior seg- 

 ments into segment 5, and expands that segment to show 

 the ocelli, which are not visible in the resting position.

large, not lashed. Antenna long, in £ longer than in $, 

 setiform, gradually fining to a long and gradually curved 

 hook ; end-segment triangular, short. Spines of abdomen
