Show 1876.] MR. A. G. BUTLER ON THE GENUS TERACOLUS. 143 I have compared our example with male specimens given to me by Mr. Ansell, from Kinsembo, and find no difference. 51. TERACOLUS LUCULLUS. (Plate VI. fig. 4.) 3. Above very like the preceding species, but the internal streak of primaries more defined, the base and costa of secondaries blackish, terminating near apex in a black costal spot; marginal spots of secondaries more distinctly separated : wings below white, primaries with the apical area sulphur-yellow, covered internally by a broad orange patch (not so broad as in T. interruptus), through the centre of which runs an angulated grey streak; a black point at end of cell; a blackish spot on iuternal area ; secondaries tinted with pale sulphur-yellow at apex ; basal half of costa orange, a blackish subapical costal spot; a black-and-orange dot at end of cell; an angulated brown marking on the disk, cut by the third median branch ; a marginal series of black dots terminating the nervures. Expanse of wings 1 inch 5 lines. 2, Teracolus loandicus (in part), Butler, P. Z. S. p. 724 (1871); Lep. Exot. p. 91, pl. xxxiv. fig. 9 (1872). 3, Ambriz, October 1872 (J. J. Monteiro, B.M.) ; 2, Loanda (coll. R. Meldola). I have no doubt that I made a mistake in referring the above female to m y T. loandicus, the differences between it and the female of T. interruptus being precisely parallel to the differences between the two males. T. loandicus will come into another section, in which the females have the marginal spots of secondaries rather small, the orange patch of primaries curved and not extending beyond the limiting streak, and an interrupted angular streak from costa to internal area of secondaries. 52. TERACOLUS GELASINUS, n. sp. 3. Nearly allied to T. interruptus, but readily distinguished by the absence of the internal streak of primaries and the small marginal spots of secondaries : wings below white, the nervures terminating in black dots, all the wings with black dots at the end of the cells ; primaries with the apex broadly sulphur-yellow, bounded internally by a rather narrow orange band, on which are a few dusky scales; sometimes a small dusky spot near inner margin beyond the middle; secondaries speckled with brown, with the basal third of costa orange, sometimes a small dusky spot on second median interspace. Expanse of wings 1 inch 4-7 lines. 3. Quanza, August 1872; 3, Ambriz, October 1872 (J. J. Monteiro). Type, B.M. 53. TERACOLUS ANTIGONE. Anthocharis antigone, Boisduval, Sp. Gen. Lep. i. p. 572. n. 19 (1836). Callosune antigone, Kirby, Syn. Cat. p. 502. n. 21 (1871). |
