 older descriptions of Euploeas without figures, is practically useless, whereas 

 Moore's may be considered good".

The species is very common in West Java. In the 6 the colour of the 

 upper side of the fore-wings is much darker than in the 9 but does not exhibit 

 any iridescent blue. The white of the upper side increases more strongly in 

 the 9 than in the c?, in some 9 this increase is particularly striking. 



The ^^^ is yellowish white and strongly oval ; it is attached with the apex to 

 the under side of a young leaf and therefore hangs perpendicularly. The larva 

 occurs repeatedly on Kcmbang pita (Strophantus dichrotomus B1.) a cultivated 

 ornamental plant. It is smooth and shining, orange in colour, sometimes 

 approaching green. The head, the posterior extremity, the stigmata, the lower 

 extremity of the legs, and the four pairs of processes, except their lower portion, 

 are black. These processes occur on the first and third thoracic and the second 

 and penultimate abdominal segments ; the anterior pair is the longest, the third 

 shortest; they are all somewhat curled in a forward direction. These processes 

 much resemble those ocurring in the flowers of the plant on which the larva 

 feeds. A splendid instance of mimicry for a superficial observer; for in this 

 manner the larva has adapted itself to its environment ! Unfortunately, however, 

 other EuPLOEA larvae, living on different plants, have similar processes. The 

 caterpillars are much pestered by Ichneumonidae and Tachiinae. The pupae 

 are yellow at first but on the second day they begin to resemble burnished 

 silver or copper, with some ochreous-yellow streaks radiating from the 

 caudal extremity and provided anteriorly with some black dots. A pupa of 

 September 8 changed into the imago on September 1 5 and one of December 1 5 

 emerged on December 23. Once I found a pupa on ^//^/^/as (Ficus Ampelas 

 Burm.).
