Genus PAPILIO. 
Passing from the Omithoptera, which may he 
esteemed the chiefs and princes of their race, we 
now come to the Papilios, properly so called, some 
of which are scarcely inferior in their dimensions 
and imposing aspect. Such, at least, is the case 
with P. Antimachus and P. Anterior, which besides 
their large size, partake of some of the other charac- 
ters of the group just referred to, and thus form the 
passage from it to Papilio. But the great majority 
are of very inferior size, and many of them so dis- 
similar in aspect that the}’- might be thought to 
afford sufficient distinctions for arranging them in 
numerous different genera. On a close examina- 
tion, however, the species are found to be so inti- 
mately allied in all essential parts of structure, that 
the most judicious systematists have not attempted 
to separate them. Such authors as have followed 
an opposite course, Hubner for example, have 
proved by no means successful in establishing sub- 
divisions ; and the only effect of such a proceeding 
is to encumber the subject with a number of generic 
names without eliciting a more philosophical ar- 
rangement, or one better adapted to aid the student. 
As at present constituted, the genus is compact and
