Hub. French Congo, Fort Champel, 1 ? . 



The genus of this species was kindly determined for us by 

 Di'. K. Jordan. 



'We take this opportunity of figuring the following two 

 remarkable and little-known African butterflies : — 



Papilio cariei, Le Cerf, Bull. Soc. Ent. de France, no. 16 

 (Oct. 1913) (Mauritius). 



A second example of this species is in the Paris Museum 

 from Great Comoro. In the Joicey coll. are two (^ cJ from 

 the Ivory Coast received from ]\Ionsieur Le Moult and 

 collected by Monsieur Dyot. Such a discontinuous distri- 

 bution is certainly curious, but we are informed by Mr. P. 

 I. Lathy, -who examined the Ivory Coast collection when it 

 came to hand, that he found the specimens in that collection. 



We regard P. cariei as a distinct species which may 

 represent the ancestral type of P. demodocus, Esp. 



Charaxes acrcenides, Druce, Ann. & Mag. Nat. Hist. ser. 8, 

 vol. ii. p. 449 (190)S) (Cameroons). S - 



The type of this species is in the coll. of Joicey and is 

 unique. As stated by Druce, /. c, this wonderful Charaxes 

 reminds one at first sight of Pseudacrcea clarki, Butl., which 

 also came in the same collection. It was taken by Rosen- 

 berg's collector, G. L. Bates, in the Cameroons.
