BUTLER ON LEPIDOPTERA [June 19, fringe soft rose-colour, but towards external angle the fringe is tipped with white; a large subapical patch of deep orange-salmon, blending with the rose-colour at apex : secondaries rose-colour ; a white diffused subapical nebula ; the surface, especially towards the base, sparsely irrorated and striated with blackish ; a black-dotted orange-salmon spot at end of cell and an imperfect angulated band, as in T. theogone, of brown : body below white. Expanse of wings 40 millim. 2 • Bather smaller than the male : in pattern nearly resembling T. procne; but the orange subapical band coloured as in the male, and the base of both wings much more widely and densely dusted with blackish ; the fringe of primaries rosy as in the male : below as in the male, but slightly deeper in colour, especially on the secondaries, where the interrupted band is gravel-red. Expanse of wings 36 millim. One slightly damaged pair, at Thagana, in woods beside Ukikuya. In the fiery colouring of the under surface this species is quite remarkable. A male variety also occurs which above more nearly approaches T. omphale, and below has the apical border of primaries and ground-colour of secondaries creamy whitish, with the band of secondaries brick-red. 97. TERACOLUS ZERA. 3 2 • Anthocharis zera, Lucas, Revue et Mag. de Zool. iv. p. 423 (1852). 3, Guaso Laschau ; 2 ? Guaso Nacrotia; 3, Ndoro, steppes at base of Kenya, 7000 feet. The description by M . Lucas probably confounds several different types (species ?); the only safe guide in the description seems to be the orange tint which he mentions as pervading the under surface of the secondaries in the male ; he, however, fails to note that on the under surface the veins are dusky; in the examples above recorded they are black towards anal angle and on the abdominal fold. The absence of the small orange spot attached to the black discocellular dot is not likely to be a constant character. 98. TERACOLUS HELLE. Teracolus helle, Butler, P. Z. S. 1876, p. 149. n. 75.
