I8H4.] LEPIDOPTERA FROM THE LOWER NIGER. 223 



21. DiADEMA ANTHEDON. 



Diadema anthedon, Doubl. Ann. & Mag. Nat. Hist. xvi. p. 181, 

 A male and female of the typical West-African form. The 

 female differs from the male in having a large discal white patch 

 divided by the nervures on the primaries, beyond which is a transverse 

 row of white spots, and towards the apex two small white spots ; 

 the inner margin is black, and the distal half of the secondaries 

 fuscous. The sexes, though obviously distinct in their markings, are 

 not strongly contrasted as in D. bolina. 



22. NePTIS AGATHA. 



Papilio agatha, Cram. Pap. Exot. t. 327. f. A, B. 

 Neptis melicerta (Fabr., nee Drury), Trimen. Rhop. Afr. Austr. 

 p. 146. 



Several specimens of this common species of Neptis are included 

 in the collection. 



23. ROMALEOSOMA AGNES? 



Romaleosoma agnes, Butl. Trans. Ent. Soc. p. 672. 



A male specimen, probably of this species, which is very closely 

 allied to R. medon (Linn.). 



The males of these two Butterflies are undistinguishable so far as 

 we can see ; but the female of B. agnes, upon which sex Mr. Butler 

 founded his name, has a darker and more restricted purple patch 

 to the secondaries than the female of i2. medon. The former seems 

 to be the prevalent form at Old Calabar and its vicinity, whilst the 

 latter seems to be more common in Angola. On this account we 

 have named Forbes's specimen -B. agnes. 



24. Hamanumida d^edalus. 



Papilio dcedalus, Fabr. Syst. Ent. p. 482. 

 Papilio meleagris, Cram. Pap. Exot. t. 66. f. A, B. 

 Aterica meleagris, Trimen, Rhop. Afr. Austr. p. 157. 

 A widely ranging species, of which two specimens are in the 

 collection. 



25. Charaxes epijasitjs. 



Charaxes epijasius, Reiche, Ferr. Gal. Voy. Abyss., Ent. p. 469, 

 t. 32. f. 1, 2. 



This species was described from Abyssinian specimens, but has 

 been since traced to Senegal. 



LyC/Enid^. 



26. LyCjENA HIPPOCRATES. 



Hesperia hippocrates, Fabr. Ent. Syst. iii. p. 288. 

 Papilio hippocrates, Donov. Ins. Ind. t. 45. f. 3. 

 Two male specimens.
