PSYCHE. 



425 



precostal nervure of hind wings short 

 or wanting ; middle tibiae shorter tlian 

 the femora in the male; eighth abdom- 

 inal segment of male posteriorly pro- 

 duced above. Egg : Tapering at base 

 almost as much as above, rounded at 

 each end, vertical ribs numerous, slight. 

 Caterpillar at birth : Uppermost ranged 

 appendages laterodorsal, conspicuously 

 longest at the extremities of the body. 

 Mature caterpillar : Piliferous papillae 

 subequal, or if very unequal the larger 

 arranged on abdominal segments in 

 transverse series. Body moderately stout, 

 tapering forward, the segments divided 

 into six sections, the head smaller than 

 any part of the body. Chrysalis : Wing 

 cases decidedly protuberant ventrally, 

 the tongue and antennae not nearly 

 reaching the uncovered part of the 

 abdomen ; prominences of body gener- 

 ally rounded, the head well distinguished 

 by its curves from the frontal projection. 



Tribe Anthocharini. 



Butterfly : Club of antennae and palpi 

 as in Pierini ; third subcostal nervule of 

 fore wing forked near the middle ; pre- 

 costal nervure of hind wing straight ; 

 middle tibiae shorter than femora ; 

 eighth abdominal segment of male pos- 

 teriorly produced above. Egg: Taper- 

 ing but little below, the base truncate 

 and summit rounded ; vertical ribs com- 

 paratively few and distinct. Caterpillar 

 at birth : Uppermost arranged appen- 

 dages below the laterodorsal line, all of 

 nearly equal length. Mature caterpillar : 



Piliferous papillae of unequal size and 

 on abdominal segments the larger ar- 

 ranged only in longitudinal series. Body 

 very slender, scarcely tapering forward, 

 the segments divided into seven sections 

 and the head much broader than high. 

 Chrysalis : Wing cases decidedly pro- 

 tuberant ventrally, the tongue and anten- 

 nae not nearly reaching the uncovered 

 part of the abdomen ; prominences of 

 body rounded, the frontal projection 

 often of excessive length with no sepa- 

 rate curve from the head. 



Tribe Pierini. 



Butterfly: Club of antennae depressed, 

 distinct, subspatulate ; palpi very slen- 

 der, elongate, the last joint long; third 

 subcostal nervule of four wings forked 

 at extreme tip ; precostal nervure of 

 hind wings bent strongly outward ; mid- 

 dle tibiae at least as long as femora ; 

 posterior margin of eighth abdominal 

 segment of male entire or notched above. 

 Egg: Tapering but little below, base 

 truncate; summit distinctly truncate, 

 vertical ribs not very numerous, sharp 

 and distinct. Caterpillar at birth : Upper- 

 most ranged appendages laterodorsal, all 

 appendages of nearly uniform length. 

 Mature caterpillar: Piliferous papillae 

 of unequal size and on abdominal seg- 

 ments the larger arranged only in longi- 

 tudinal series. Body comparatively stout, 

 scarcely tapering forward, the segments 

 divided into six sections and the head 

 scarcely or not at all broader than high. 

 Chrysalis: Wing cases not ventrally
