Show 1894.] MANICA, SOUTH-EAST AFRICA. 65 28th March. It is of the typical form, proper to the wet season, without any trace of ochre-reddish colouring on the underside. Genus TERACOLUS, Swains. 122. TERACOLUS ERIS (Klug). Pontia eris, Klug, Symb. Phys. t. vi. figs. 15, 16 (1829). Oue specimen only, taken in the Mineni Valley on 31st March. This is a perfect and very large male (exp. al. 2 in. 2 lin.), with the inner-marginal black band of the fore wings as broadly developed as in King's figure, but still marked externally between 2nd and 3rd median nervules with a minute white spot. In the hind wings, however, the costal black band does not extend below the 2nd subcostal nervule, but the hind-marginal nervular black marks are decidedly larger than in Klug's figure. The underside is almost pure white, with the inferior submarginal black spots (3) very strongly marked ; and it also presents the peculiarity of blackish hind-marginal termination to the nervules, more pronounced in the fore wing than in the hind wing. 123.

Five males, taken in the Mineni Valley from 6th to 26th March, agree thoroughly with those described by m e (op. cit. p. 102) from Transvaal and Delagoa Bay; the upperside presenting fine but complete black neuration of the hind wings, and the underside being almost uniformly white, with no markings beyond the terminal discocellular dots, a faint trace in the hind wings of the costal commencement of a discal ray, and (in one specimen only) dusky terminations of the nervules on hind margin. North Ovampoland must be added to the geographical range of this species, Eriksson having taken six males and three red-tipped females near Ovaquenyama in February and March 1891. The males are rather small (one, indeed, being dwarfish) and approximate the Var. A described by m e in S.-Afr. Butt. iii. p. 103, but on the white underside the black neuration is very variable, being pretty well expressed (though very fine) in two examples only, at extremities alone in two others, and wanting altogether in the remaining two ; while the discal streak in the hind wings is developed in but two examples, and imperfectly in one of those. The females, though heavily blackish-marked on the upperside, are less so than in Transvaal examples, especially as regards the borders of the apical patch in the fore wings and the hind-marginal border in the hind wings, the latter being macular instead of continuous. Their underside is very pale yellowish, with the discal ray of the hind wings dull ferruginous and not strongly marked; there is no black neuration except in one ex- PROC. ZOOL. SOC-1894, No. V. 5 |
