Genus PAYONIA. 



The group composing this genus was separated from 

 the preceding by Godart, chiefly on account of the 

 discoidal cell in the secondary* wings being closed. 

 Besides this character the k palpi are not so densely 

 clothed with scales, and the inferior nervure of the 

 upper wings is curved near its origin in the form of 

 the letter S. The species very closely resemble the 

 Morphos in most other respects, but their colours 

 are generally less brilliant. They are all from South 

 America, and in that country they are far most abun- 

 dant in Brazil. The caterpillars of several different 

 kinds have been represented by Madam Merian, and, 

 like those of Morpho, they differ from each other 

 in their appearance and properties.
