Although not caught in copula, there is no doubt in this case that the sexes are conspeciflc. The width of the vulva is evidently correlated with the width of the supra-anal lobe; and the fusion of the dorsal plates of the Xth tergite may help to give more support to this accessory copulatory structure. The clear streaks on the wings are not peculiar to this species, being present in all the South African Nemourines; but here they are very conspicuous owing to the very deep suffusion of the wing membranes. While some of the other species of this genus, and of Aphani- cercofsis, are of a deep brown colour, sometimes very dark brown VOL. XXX, PART 4. 36.
