GENUS PAPILIO. LINNAEUS. 



Generic character. The antennae growing thicker 

 at the extremities, in general, club-shaped, or capi- 

 tated ; the wings, when at rest, erect, and meeting 

 upwards. The species all fly by day. 



This genus comprehends those insects called in 

 English Butterflies, which fly by day. The first pair 

 of legs in some of them are short, and used rather as 

 hands for cleaning themselves, than as feet for walking. 

 Their flight is in general quick. The caterpillars 

 have all sixteen feet, and are for the most part prickly. 

 Some, however, are smooth, others set with short 

 hairs ; some have a sort of tail, and others have two 

 blunt horn-like feelers on the head. 



Linnasus divides this genus into six families. The 

 names of the first, being mostly exotic, he has taken 

 from those of the Trojan and Grecian chiefs ; those 

 of the others, as most of them are European, and 

 their history and habits better known, are taken 

 chiefly from the plants on which the caterpillars feed.
