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? Bomaleosoma agues, Butl. Trans. Ent. Soc, p. 672. A male specimen, probably of this species, which is very closely allied to B. medon (Linn.). The males of these two Butterflies are undistinguishable so far as we can see ; but the female of B. agues, upon which sex Mr. Butler founded his name, has a darker and more restricted purple patch to the secondaries than the female of B. 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. agues. 24. HAMANUMIDA D^EDALUS. Papilio dadalus, 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 EPIJASIUS. 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. LYCJENID^E. 26. LYCENA HIPPOCRATES. Hesperia hippocrates, Fabr. Ent. Syst. iii. p. 288. Papilio hippocrates, Donov. Ins. Ind. t. 45. f. 3. Two male specimens. |
