Individual differences occur in the present species ; the colour of the upper 

 side, even of the hind-wings, being darker in some specimens than in others; 

 in the size and number of the white spots on the upper side of the fore-wings 

 there is also some difference. The structural blue in that region is not equally 

 developed in all c?, while in the 9 only traces of it, at the most, are present 

 and frequently it is entirely wanting. In spite of this I have failed to establish 

 local differences between the numerous specimens I have been able to compare. 



The caterpillar lives on Scrouf (Streblus asper Lour), Waringin (Ficus 

 BENjAMiNEA L.), Ampclos kcbo (Ficus AMPELos Burm.), Gcgareman (Ficus 

 HETEROPHYLLA L.), Roiikem besar (Flacourtia Rukam Z. and M.). It is black, 

 the head shining. On the back occur about ten white transverse streaks, the 

 outermost single, but the others mostly double or even treble; they are so 

 wide sometimes that nearly the whole back becomes white. At times they are 

 continued at the sides as single vertical white lines which do not always coincide 

 with the dorsal streaks or may be entirely wanting. A blood-red spot occurs 

 at the sides of the third thoracic and the six foremost abdominal segments. 

 Four pairs of black dorsal processes, about equal in length, are found on the 

 second and third thoracic and the second and penultimate abdominal segments; 

 these processes are mostly curved forward a little. 



The pupa is yellow with brown streaks at first but on the second day it 

 becomes like burnished silver or copper with grey and brown streaks radiating 

 from the caudal extremity. From a pupa of December i^' the perfect insect 

 developed on December g''' while one of April 6 and one of April 1 4 emerged 

 on the 14"^ and 24I'' of April respectively.
