Show 1897.] BUTTERFLIES OF THE GENUS TERACOLUS. 25 49. TERACOLUS EPHYIA. Pontia ephyia, Klug, Symb. Phys., Ins. pl. vi. figs. 9 & 10 (1829). Anthopsyche clemagore, Felder, Reis. Nov., Lep. ii. p. 186 (1865). The females associated with T. ephyia in the British Museum appear to me to be wrongly placed, as they are inseparable from those of the very different T. microcale, Butl. T. clemagore, with reduced black markings above and pinkish underside, I take to be the dry-season form of this species. Recorded from Dongola and Upper Egypt. 50. TERACOLUS LIAGORE. Pontia liagore, Klug, Symb. Phys., Ins. pl. vi. figs. 5-8 (1829). This distinct little species, which belongs to the T. evarne group, seems to be decidedly scarce. Klug records a single male from Dongola, there is a male from Upper Egypt in the British Museum, and I have seen one other from Suakin. 51. TERACOLUS AUXO. Anthocaris auxo, Lucas, Rev. Zool. p. 422 (1852). Anthocarls evarne, Boisduval (nee Klug), App. Voy. Deleg. p. 587 (1847). Anthopsyche evarne, Wallengren, K. Sv. Vet.-Akad. Handl.; Lep. Rhop. Caf. p. 14 (1857). Anthopsyche eucharls, ? var., Wallengren, ibid.; ibid. p. 15 (1857). Anthopsyche topha, Wallengren, Wien. ent. Monats. p. 34 (I860). Anthopsyche keiskamma, Trimen, Rhop. Afr. Aust. p. 56, pl. ii. figs. 2 & 3 (1866). Teracolus syrtinus, Butler, Proc, Zool. Soc. p. 163(1876). T. auxo represents the wet-season form, and T. topha ( - keiskamma) the dry. As Mr. Trimen has pointed out, the two types of T. syrtinus, Butl., from Lake Nyasa and Senegal, are inseparable from T. auxo ; but the remaining specimens associated with them in the British Museum appear to me to be referable to the nearly allied T. evarne (Klug). The above specimens of P. syrtinus are the only examples of true T. auxo that I have seen from localities north of the Zambesi. To the south of that river it is plentiful in suitable spots throughout the eastern side of the continent. 52. TERACOLUS INCRETUS. Teracolus incretus, Butler, Ent. Mo. Mag. xviii. p. 146 (1881). Callosune vulnerata, Staudinger, Exot. Schm. pl. xxiii. (1884). This handsome species is the Central-African representative of auxo, and inhabits a broad belt of country lying between Mombasa and Victoria Nyanza. It has the bright yellow colouring of the Southern species, as opposed to the whiter tints of T. evarne (Klug) ; but differs in its much larger size and in the black markings on primaries, there being no sign of black on the inner edge of apical patch, and the hind marginal border being narrow, not extended to posterior angle nor dilated as in T. auxo.
