T. loandlcus, from Angola, and procne, from Swaziland and Orange River, are quite alike, and represent the small, lightly-marked variety of T. theogone, which prevails in dry localities and in the higher plateaux of the interior. T. delphlne, Butl. (nee Boisd.), is represented in the British Museum by six examples-two males and one female from S. Africa, and three males from the Niger. The males are interesting, as they exhibit the gradual gradation of colouring from T. theogone to typical T. evippe on the upperside, and although they are white beneath they show more or less faintly the dusky discal bar in hind wings so characteristic of T. theogone. T. angolensls, from Angola and the Congo, is similar to the preceding, but has quite lost the dusky bar beneath, and closely resembles typical T. evippe, though the apical patch is more like that of T. theogone. T. pseudocale is recorded from Swaziland, and, as I have stated above, I can only regard it as an intermediate seasonal form of t the variety T. omphale, though at the same time it is quite similar to T. angolensls. The female is somewhat like a dwarfed T. theogone, but shows an approach to T. evippe in its reduced discal black markings. T. ocale is only a larger form of T. pseudocale, and although tbe single female in the British Museum generally resembles that of T. evippe, yet it has the distinct red apical band of the var. omphale. T. arethusa, chorea, hanna, amytis, and cebrene are all referable to typical T. evippe (Linn.). 58. TERACOLUS SUFFUSUS. Teracolus suffusus, Butler, Proc. Zool. Soc. p. 152, pl. vi. fig. 10 (1876). This little species is founded on a single female from Angola, which looks not unlike a dwarf specimen of T. evippe-omphale, but the basal black in fore wing extends from inner margin to costa, and continues outwardly almost to the extremity of the discoidal cell. I cannot attribute it to any described male. 59. TERACOLUS MICROCALE. Teracolus microcale, Butler, Ann. Mag. N . H . (4) xviii. p. 487 (1876). This species is only recorded from Abyssinia in the north-east, and the Orange River in the south-west. It looks very much as if it were only a dwarfed and under-coloured local variation of T. evippe, and the localities in which it occurs lend some colour to this view. However, in view of the paucity of specimens it seems |
