156 MR. A. G. BUTLER ON THE GENUS TERACOLUS. [Jan. 18, Anthocharis eupompe, Boisduval, Sp. G-e'n. Lep. i. p. 571. n. (1836^ Callosune eupompe (part), Kirby, Syn. Cat. p. 501. n. 13 (1871). 2 . Papilio evippe, Cramer (nee Linnaeus), Pap. Exot. l. pl. yi. figs. D and E (1779). , xy Anthopsyche theopompe, Felder, Reise der Nov. Lep. n. p. 183. n. 175 (" 1865 ") ; Hopffer, Stett. ent. Zeit. p. 432 (1869). 3, White Nile -(Petherick). B.M. I have examined both sexes of this species, taken by Mr. J. K. Lord at Akeek (island). 101. TERACOLUS ANTEUPOMPE. Anthopsyche anteupompe, Felder, Reise der Nov. Lep. ii. p. 184. n. 175 (1865). Callosune anteupompe, Kirby, Syn. Cat. p. 501. n. 14 (1871). Bogos. 102. TERACOLUS ACASTE. 2 . Pontia acaste, Klug, Symb. Phys. pl. 7. figs 16, 17 (1829). Pieris poly caste, Boisduval, Sp. Gen. Lep. i. p. 525. n. 127 (1836). Ambukol. I much doubt whether this female would not be better placed next to T. halimede, of which Klug says it may be a variety; it is, I should say, more probable that it is the female of T. pleione than a variety of T. halimede. 103. T E R A C O L U S PSEUDACASTE, n. sp. (Plate VI. fig. 11.) 3 Anthocaris (sic) eupompe, Lucas, Lep. Exot. pl. 36. fig. 4 (1835). Underside like T. cinerescens, but without the blackish line across the cell of primaries or the orange costa to secondaries. Expanse 1 inch 9 lines. 2 . Very like Klug's figure of T. acaste, but larger and darker, the apical area of primaries greyish brown, crossed by a curved series of whitish lanceolate streaks, bounded on the inside by black spots. Wings below like the male of T. cinerescens. Expanse of wings 2 inches. 3 2 , White Nile (Petherick). Type, B.M. This species is a link between the T.eupompe and halimede groups. 104. TERACOLUS DEDECORA. Anthocharis dedecora, Felder, Reise der Nov. Lep. ii. p. 184. n. 177 ("1865"). Callosune dedecora, Kirby, Syn. Cat. p. 502. n. 15 (1871). 3 2, Senegal. _ B.M. The female forms a link between the T.-eupompe and antevippe groups. It is the Anthocharis eupompe, var., of Trimen (Rhop. Afr. Austr. p. 46), but it is ticketed " Seneg.," not S. Africa. The long description is taken from an Indian species, there being no African butterfly to which it will apply.
