 a. [larva and pupa). 



Among the most remarkable of those lav\s which belong to 

 the natural system, is that which assigns to every great 

 division of our globe its peculiar races of animals : and these 

 in numerous instances, are so marked, that a naturalist 

 would no more expect to find such genera inhabiting a dif- 

 ferent continent, than a Physiologist would hope to discover 

 a race of Hottentots among the Highlands of Scotland. It 

 is under the tropical latitudes of the old world (and chiefly 

 those of Asia), that nature has placed the group of butterflys 

 which we now, for the fiust time, characterize. Distin- 

 guished, in the most beautiful manner, by their larva and 

 pupa, they shew, even in the external appearance of the 

 perfect insect, an unerring distinction, in the dark stripes 

 between the nerves of the anterior wings. We have indeed, 

 in the tropics of America, a race of black and crimson 

 butterflys representing these of India ; but they belong to a 

 very different group ; and are known at the first glance by 

 their broader wings, totally destitute of the stripes just 

 mentioned. 



M. M. Latrielle and Godart, are evidently mistaken 

 regarding the insect figured by Clerk, which they consider 

 to be the female of Polydorus ; this error we have ascer- 

 tained from fine specimens of both sexes, sent from Java 

 and now in our possession. We have figured the male, 

 and Dr. Horsfield has enabled us to add the Caterpillar 

 and Chrysalis.
