the order Lepidoptera, as being the perfection of the Lepidopterous type. This position 
might be disputed with them by the Satyrince on account of the degree of atrophy of the 
fore legs, which is perhaps as great in some species of SatyrvniB as it is in the most 
advanced genera of Banaoid Heliconidce. The order of affinities does not range in a 
line ; there are branches ; and so it may happen that two groups may be nearly equal in 
their grade of perfection through each standing at the head of its branch. The true 
relationships of the groups of Rhopalocera may be therefore better explained by a diagram.

A common and well-known insect. It is found in waste grounds and open pla( 
everywhere throughout the region of the Lower Amazons. Its larva feeds on Asclep 
Curassovica.
