AFRICAN SPECIES OF PAPILIO. 153 
Species XXII.—PAPILIO TROPHONIUS. (Plate 39, fig. 1, 2.) 
Syn.—Papilio Trophonius, Westw. in Ann. Nat. Hist. 
Papilio Cenea, Stoll, pl. 29, fig. 1. (nec P. Cenea, Linn.) 
This species, which has been overlooked by M. Boisduval, bears 
considerable resemblance to several of the preceding species, but 
differs from them all in the colour of the pale portion of the wings. 
In the specimen figured the wings of the upper side are dark 
brown, with a large fulvous red patch, occupying a large space 
along the inner margin of the fore wings, and the greater portion 
of the hind wings, with a rather narrow edge of brown with white 
spots arranged in pairs on the hind wings. The fore wings have 
also a clay-coloured oblique bar running nearly across the discoidal 
cell, with a large pale patch beyond its extremity, and several small 
submarginal pale spots. On the under side the arrangement of the 
colours of the wings is nearly similar, except that, as in all the 
allied species, the extremity of the fore wings is pale clay-coloured 
brown, and the veins, as well as the intermediate longitudinal striz, 
are darker brown. The body is brown, spotted in front with white ; 
the abdomen buff, with a longitudinal dorsal stripe, brownish- 
black, and the sides with two rows of dark dots. 
Stoll’s figures agree with other specimens in the cabinet of the 
British Museum, and my own, in which the fore wings have an 
oval patch of pale clay colour behind the middle of the discoidal 
cell, and the clay-coloured portion of the hind wings does not extend 
beyond the middle of the wing. The pale spots on the fore wings 
are also much smaller than in the specimen figured by me, and the 
base of the hind wings is also brown on the upper side. It is possible 
that these latter may prove to be specifically distinct from the more 
richly-coloured specimen which I have figured, as I believe the 
allied species of Papilio do not exhibit such marked sexual differ- 
ences. In such case the name of Trophonius should be retained 
for the species here figured; and Stoll’s kind may be named 
P. Ceneus, although his statement that his insect is a ‘“‘ Nymphe 
aveugle a quatre pieds,” and his error in giving to the species a name 
employed by Linnzeus for a different species of Papilio, scarcely 
warrant the retention of his specific name. It is a native of 
Guinea and Caffraria. 
Species XXIII.—PAPILIO ADAMASTOR. (Plate 38, fig. 3.) 
Syn.—Pap. Adamastor, Boisduval, Sp. Gen. Lep. 1, 371. 
Deseribed by Boisduval, from a specimen sent to him by M. Wes- 
termann, who had received it from the coast of Guinea. Mr. Hope
