vided by the nerviires, commencmg in the discoidal cell of the an- 

 terior wing, and terminating on the inner margin of the posterior 

 wings, of which it occupies fully two-thirds. This band is nearly 

 straight on its inner side, but externally it is suddenly widened be- 

 low the radial nervure of the anterior wings, and much dentated on 

 the posterior wings. It is preceded on the costa by a large sub- 

 quadrate spot of the same colour divided into four by the nervures. 

 At the apex of the anterior wings are two elongate green spots, 

 followed on the outer margin by a series of geminate spots and 

 a simple round one at the anal angle of the same colour. On 

 the posterior wings, towards the outer margin, are three rounded 

 green spots, each followed by a small dot of the same colour 

 (sometimes very indistinct). These are succeeded by three ge- 

 minate spots ; the first rounded, the second elongate, the third 

 rounded, near the anal angle and almost touching the transverse 

 band. Below fuscous, the anterior wings darker at the base ; to- 

 wards the anal angle a marginal series of five or seven small 

 white spots placed in pairs between the nervules, between which 

 and the margin are two or three very minute white dots. Pos- 

 terior wings with three black striae in the cell, a macular band 

 of a pale gold colour near the outer margin, and two points of 

 the same colour near the anal angle. 



Head and thorax black, spotted with white. 



Abdomen fuscous, above with the edges of the segments paler, 

 below with five series of white spots ; anal valves rounded. 



This species is closely allied to P. Nireus, but has the band 

 much wider and somewhat different in its direction, and the anal 

 valves are much rounder. I may here remark that the P. Nireus 

 of Cramer, t. 378. f. F. G, from the Cape of Good Hope, is quite 

 a distinct species from the true Nireus of the west coast of Africa. 

 The distinctions were clearly pointed out to me by Dr. Boisduval, 

 who had placed the name Char opus to it in his cabinet about four 

 years ago. This name having been lately used by Mr.Westwood 

 for a species in my brother^s collection, the name cannot be now 

 used for the Cape insect. I therefore propose for it the name of 

 JjycEus. It may be known from P. Nireus by its generally smaller 

 size, its cilia spotted with white, the apex of the anterior and disc 

 of the posterior wings below clouded with silvery gray, and by 

 the band of the posterior wings not being macular. This band is 

 wanting in the females, the whole of the disc and outer margin 

 of the posterior wings, and the apex of the anterior being clouded 

 with light brown with silvery reflections. Only having seen im- 

 perfect specimens, when I drew up the catalogue of the Papilionidce 

 in the collection of the British Museum, I was afraid to sepa- 

 rate the Cape specimens, not being then aware that Dr. Boisduval, 

 from the examination of numerous perfect specimens, had become
