Omrora (August and November), Ehanda (September), and Humbe (October). Eight examples ; six males and two females. Mr. Eriksson's specimens all show a difference from more southern examples in having the apical portion of the black border of the fore wings with a more prominent inward projection, so as more to resemble the corresponding markings in T. butleri, mihi. Moreover, two of the males taken in the summer at Humbe and Omrora respectively approach T. butleri in the absence of the usual underside markings; and another male from Omrora (November) has the same markings only slightly developed. 82. TERIAS BUTLERI, Trim. cf 2 • Terias butleri, Trim. S.-Afr. Butt. iii. p. 23. n. 244 (1887). Omrora (November), Humbe (October), and Okavango River (December).

Terias regularis, Trim. op. cit. p. 26. n. 246 (1887). Ehanda (September). One female example. It is with some doubt that I refer this specimen to the species named, as on the upperside it has the fore-wing border considerably narrower apically, and the hind-marginal nervular marks reduced (as in T. desjardinsii, Boisd., § ) to dots, while on the underside there is a decided rufous tinge over the margins of the hind wings and the apex of the fore wings and the ordinary markings are obsolescent. Except in its being narrower apically, the fore-wing border agrees with that in the female T. regularis ; and altogether the specimen is intermediate between this form and the closely-allied T. desjardinsii.
