CATALOGUE OF 



The antennae, in the genus Papilio, exhibit three subdivisions. 



First, antennae filiform at the base, marked along their entire 

 length with prominent annular rings, and terminated by a cylindrical 

 club, which is attenuated at both ends. This division is exemplified 

 in the following species of this Catalogue, viz. : — 



Pap. Memnon (No. 202). 



Polymnestor (No. 203). 

 Helenus (No. 205). 

 Polytes (No. 208). 

 Pammon (No. 209). 



Pap. Demolion (No. 210). 

 „ Erithonius (No. 211). 

 „ Arjuna (No. 212). 

 „ Xuthus (No. 223). 

 „ Machaon (No. 224). 



And by the metamorphoses of these species, viz. :—

„ Xuthus, „ IV. f. 1

 „ Helenus, „ III.f2,2« 



„ Polytes, „ III.f.3,8« „ Machaon, „ IV.f.2,2« 



„ Pammon, „ III. f. 4,4a 



The larva of this division is characterized by a smooth surface, and 

 by a swelling or intumescence of the fourth or fifth segment of the 

 body, from which it tapers more abruptly to the head, and in a 

 gradual manner to the anal extremity. It is typical of the whole 

 stirps, and represents, par excellence, the Chilognathiform division. 



In the second division of the genus Papilio, the antennae agree in 

 form and outline with those of the first, but the annuli, or rings, 

 along their entire length are comparatively obscure. This division 

 is exemplified in the following species of this Catalogue, viz. : — 



Papilio Hector (No. 189). 

 „ Diphilus (No. 190). 



Ornithoptera Darsius (No. 176). 

 „ Pompeus(No.l77). 



Papilio dissimilis (No. 187). 

 And the metamorphoses of the same species, which are figm-ed on 

 Plate II., figs. 1, 2, 3, 4, and 5. 



The larva of this division is cylindrical, very slightly attenuated at 

 the ends, somewhat thick and fleshy, smooth on the surface, and 

 provided with short obtuse tubercles along its entire length. It 

 represents the Chilopodiform modification of the genus Papilio. 



In the third division of the genus Papilio, the antennae are slender, 

 filiform at the base, but terminated by an oval, comparatively enlarged 

 compressed club, on which the annuli are closely arranged and
