Imago. — First pair of legs in both sexes as fully developed in all 

 respects as the other pairs. Discoidal cell always closed in both fore 

 and hind wings. 



Larva.— In Fierince cylindrical, tapering to each extremity, without 

 processes or other appendages, usually with very short pubescence : in 

 Papiliotmm stouter, often thickened towards anterior extremity, smooth, 

 or with long tubercular prominences, possessing on second (prothoracic) 

 segment an exsertible strongly- scented forked tentacle. 



Pupa.— More or less angulated ; head singly pointed in Fierince, 

 bifid in Papiliojiince ; attached erectly, obliquely, or horizontally, by 

 the tail and by a girth round the middle. 



The two Sub-Families, Fierince and Fapilionince, which compose 

 this Family, are readily distinguishable by the characters of the per- 

 fect insect. The Fierince have in the fore-ivings the first disco-cellular 

 nervule either obsolete or very short ; the third disco-cellular and lower 

 radial nervules disposed as in other butterflies; the branches of the 

 sub-costal nervure varying in number from three to five ; no interno- 

 median nervule; and the internal nervure rarely present, and then 

 very short and slender, and running into the submedian nervm-e : in 

 the Uncl-ivincjs the inner margins are convex, forming a groove or 

 channel beneath the abdomen, and the internal nervure is long and 

 strong; the precostal nervure is always simple. The palpi are of 

 moderate size and porrected ; the antennas have a straight club. The 

 legs are short, and there is no appendage to the tibia of the first pair ; 

 the tarsal claws are bifid, and usually provided with pulvilli and paro- 

 nychia. The abdomen is slender, and nearly always of moderate length
