To this division, as it is typical not only of the genus, but also of tht; 

 whole stirps, and exhibits the most perfect production of the order. 

 Lepidoptcru, V would reserve the Linna^an name FnpiUo. 



" Secondli/. The antennae agree in form and outline with those of 

 the first, but the annuli, or rings, along their entire length, are com- 

 paratively obscure." 



" The larva is cylindrical, very slightly attenuated at the ends, some- 

 what thick and fleshy, smooth on the surface and provided with short 

 obtuse tubercles along its entire length." 



This is the Chilopodiform modification of the genus Papiliu. and to 

 which I have assigned the name of Pacldiopta. 



It is represented by the following species : — 



Ornithop. Darsius. Pap. Hector. 



" Pompeus. " Diphilus. 



" Rhadamanthiis. " Philenor ? 



" Priamiis. " Polydamus? 



Paj"). dissimilis. 



" Thirdhj. The antennae are slender, filiform at the base, but ter- 

 minated by an oval, comparatively enlarged, compressed club, on which 

 the annuli are closely arranged and crowded." 



" The larva is smooth, slightly attenuated towards the extremities, 

 somewhat broader or arched in the middle, and marked with regular 

 transverse bands ; but its chief character consists in two projecting 

 points from the abdomen." 



It is exemplified by the following species : — 



Pap. Sarpedon. Pap. Marcellus. 

 " Agamemnon. " Ajax. 



" Eurypylus. " Podalirius? 



" Antiphates. " Siiion. 



These form the Thysanuriform division of the genus Papillo, and 

 which I have called Pathysa. 



The names which I have here proposed are not arbitrary, but have 

 been derived from the union of the first syllable of the generic name, 

 with those commencing the analogical name of the larval form : to 

 complete the series in all its forms, we should then call the first sub- 

 genus, as yet unknown. Pavermia, and the fifth, Panopluia.
