the inner side of the tibi^. Dorsal margin of the eighth ab- 

 dominal segment of ^ notched or produced to a hook. Upper 

 organ of ;^ genitalia with no lateral processes. £gg sub- 

 globular and smooth, or very much elevated and longitudinally 

 ribbed ; (one known exception occurs in Parnassius, in which it 

 •is tiarate, but where, in contradistinction to the Lycaenidae, it 

 appears to be overlaid with raised polygonal plates). Larva at 

 birth, so far as known, furnished with longitudinal series of 

 clubbed or forked hairs or with prickly tubercles. Mature 

 larva cylindrical or enlarged anteriorly, covered with very short 

 pile (in some exotic forms with long hairs), mostly arranged in 

 transverse rows, or with rather infrequent and irregularly dis- 

 tributed minute hairs, and often also with series of fleshy tuber- 

 cles or filaments or glabrous scarcely elevated warts. Clu-y- 

 salis elongate, unimucronate or bimucronate in front, generally 

 with numerous angular projections. Median girth frequently 

 free from the body for a considerable part of its course by the 

 ventral extension of the wing sheaths, the ventral surface of the 

 body being generally bent near the middle. Cremaster strongly 

 protuberaiit and free, the hooks apical. Fam. III. Papili- 

 oiiidce (Pierinse -f- Papilioninse). 

 B. Imago of small or medium size, usually robust, with rather small 

 wings. Head in a horizontal plane, the tongue being inserted opposite 

 the middle of the eye or even higher. Antennae widely separated at the 

 base, the space between them more than equalling half the vertical dia- 

 meter of the eye, the tip of the club more or less distinctly pointed and 

 recurved. Eyes usually overhung at the outer base of the antennae by a 

 curving pencil of bristly hairs, the cornea extending over almost the entire 

 ocellar globe. Almost invariably the front tibiae have a foliate epiphysis 

 on the inner side, and the hind tibiae a middle pair of spurs in addition 

 to the terminal pair. Inner edge of hind wings plaited, the fore and hind 

 wings in repose often resting in different planes. Egg never notice- 

 ably higher than broad, hemispherical and smooth or domed and verti- 

 cally ribbed. Larva at birth. — Head always broader and higher than 

 the body, the latter with ranged fungiform appendages, never, excepting 

 on the seventh and eighth abdominal segments, so long as the segments. 

 First thoracic segment with a distmct corneous dorsal shield. Mature 

 larva cylindrical but slightly flattened beneath and stoutest in the middle,
