LEPIDOPTERA. 125 



male with the mark of Papilio R. Phcedrus, and two females with that of P. R. JEsopus, in Fabricius' own 

 hand-writing. The decision of the authors of the Encyclopedie, above referred to, according to which 

 the P. R. Msopus of Fabricius is not a distinct species but the female of Phcedrus, is confirmed by a 

 careful dissection which is intended for a future plate.

Hinder wings gradually attenuated towards the anal region, with a slightly rounded inner apical 

 angle; upper surface (in the male) with a bright cupreous lustre inclining as the light varies to 

 reddish-brown ; exterior and posterior borders of the fore wings and posterior border of the 

 hinder wings black, in the former the intermediate boundary forms a bold curve leaving a broad 

 apex, in the latter the inner edge is slightly waving and evanescent ; the concave inner margin 

 which receives the abdomen is paler and covered with delicate hair of a sooty tint : underneath 

 satin-white, the colour being spread in an opaque pulverulent stratum uniformly over the whole 

 surface and covered with a silvery slightly glaucous gloss; behind the disk two very delicate 

 waving strigae of a blackish tint pass regularly over both pairs, the anterior being more pro- 

 nounced ; just within the hinder margin is a series of very minute black dots and near the 

 middle of the inner margin stands a solitary dot of the same colour ; on the disk the indication 

 of a transverse brownish litura is faintly observed, which however is more lengthened and dis- 

 tinct in the hinder pair. All the wings have along their posterior margin a grayish line. Body 

 and abdomen above glaucous inclining to brown with a lengthened down of the same colour ; 

 underneath yellowish white and pulverulent; legs of the same colour with obscure brown spots. 

 Antenna brown. 



Two males in excellent condition have furnished the materials for the preceding description ; the female 

 was not observed, and the history of this species remains therefore imperfect. The form of the hinder 

 wings indicates a sectional division in this small group.
