PSYCHE. 



[December, 1902 



protuberant, the tongue and antennae 

 reaching the uncovered part of abdo- 

 men ; carinae often raised to sharp pro- 

 jections. 



Subfamily PAPILIONINAE. 



Butterfly: Antennae more or less 

 arcuate. Median nervure of fore wings 

 with four branches ; hind wings not 

 enclosing the abdomen, often plaited on 

 the inner margin. Fore tibiae with a 

 distinct epiphysis on the inner s*ide ; 

 each of the claws simple and long ; par- 

 onychia lacking. Usually of large size. 

 Egg: Spheroidal or oblate spheroidal, 

 at most scarcely higher than broad, gen- 

 erally broader than high, all surface 

 structure, when visible, reticulate. Cat- 

 erpillar at birth ; Head with no retro- 

 arcuate posterior dorsal curve, but par- 

 tially covered by a fold of the segment 

 behind. Body more or less angulated 

 at the lateral line with ranged papillae 

 most or all supporting several append- 

 ages. Mature catcrpUlar: Head much 

 smaller than the succeeding seg- 

 ments, more or less covered posteriorly, 

 where there is no retroarcuate dorsal 

 curve, by a fold of the segment behind. 

 Body frequently enlarged at the hinder 

 end of the thoracic region, nearly naked 

 or with longitudinally ranged fleshy fila- 

 ments, or bristly mamillae, occasionally 

 with transversely ranged piliferous papil- 

 lae ; o-enerally transversely marked or 

 saddled with sharply contrasted colors, 

 or where longitudinally marked it is by 

 serial spots and not by stripes; a Y- 



shaped osmaterium on first thoracic seg- 

 ment. Chrysalis : Anterior extremity 

 ending in a pair of projections — the 

 ocellar prominences — thrust some dis- 

 tance in front of the antennae, or with 

 rounded front not projecting beyond the 

 base of the antennae, occasionally ( in 

 exotic types) with a double knob of 

 hooks. Dorsal surface of the abdomen 

 ridged if at all on the laterodorsal line ; 

 /. e. double. Girt crossing the middle of 

 the metathorax. 



Tribe Parnassini. 



Butterfly: Last joint of palpi long; 

 wings rounded, in our species entire, 

 the subcostal nervure of fore wings with 

 three superior branches.* Egg: Very 

 oblate spherical, deeply and profusely 

 punctate. Caterpillar at birth : Bristles 

 of body spiculiferous not apically ex- 

 panded but truncate. Mature cater- 

 pillar: Body with ranged tubercles 

 bearing bristly hairs or clothed with 

 bristly hairs massed in distinct regions. 

 Chrysalis : With no frontal projections, 

 sometimes enclosed in a cocoon, or 

 attached (in Tha'is) by the anterior 

 extremity. 



Tribe Papilionini. 



Butterfly: Last joint of palpi min- 

 ute; wings subfalcate, the hind pair 

 usually tailed, the subcostal nervure of 

 fore wings with four superior branches. 

 Egg: Nearly spheroidal, with scarcely 



•These characters do not hold for the entire group, out- 

 side of America, where it is less developed.
