SYMBOLS OF PSYCHE. 183 



resemblance to dead leaves ; but the best example, 

 perhaps the most perfect case of protective resemblance 

 known, is to be found in the Indian butterfly Kallivia 

 inackis, and its Malayan ally, Kalliina paralckta, both 

 showy and conspicuous insects on the wing, but which 

 no sooner alight than, as if by magic, they become 

 invisible. Amid dried or dead leaves, on trees and 

 bushes, it is their habit to rest, and in this position, with 

 the wings tightly pressed together, they form a direct 

 and finished representation of a leaf in some stage of 

 decay. Colour, form, and habits all combine to produce 

 this complete and marvellous disguise, and the protec- 

 tion it affords is shown by the abundance of individuals 

 that possess it (see Fig. 34).
