TRIMEN ON BUTTERFLIES [Jail. 20, Mr. Eriksson's specimen differs from that described and figured by Hopffer in several particulars, but is unfortunately worn and with the hind wings injured about the anal angle. On the upperside all the black spots are reduced in size ; in the fore wings the fuscous hind-marginal border is almost wanting, and the subapical oblique costal ray is narrower and whiter ; and in the hind wings there is no ochre-yellow colouring immediately beyond the median series of spots, but an additional small black spot occurs just beyond extremity of the discoidal cell. The underside is of a much deeper ochre-yellow, which in the hind wing to beyond middle is much more restricted, while in the fore wing the costal-apical area is streaked by internervular longitudinal bluish-white rays; and on the disk of the fore wings, between the third and a point a little below the first median nervules, there is a conspicuous fuscous cloud, almost obliterating the lowest two spots of the submarginal series, and emitting nervular rays towards base. It is difficult to understand how Hopffer could have referred this butterfly to the genus Harma, as it is a true Crenis (not distantly allied to C. rosa), but singular in its possession of a common median row of black spots, and on the upperside of the fore wings also black discocellular striae like those in the genus Arggnnis. Hopffer himself notices the resemblance in size and form of the wings to the female Arggnnis laodice, and the likeness extends also to the black markings of the upperside generally.

Handl., Lep. Rhop. Caffr. p. 29. n. 2 (1857). Omrora (August), Ehanda (September), Okavango River (December), andOmaramba-Oamatako (January). Fifteen examples : four males and one female of the typical form ; eight males and two females of the var. acheloia. Both the typical form and the variety were taken on the River Okavango and Omaramba-Oamatako, and the variety also at Omrora and Ehanda. Both varied from the medium to the light coloration of the underside, only one example (a male of the variety from Omrora) exhibiting the deep-ferruginous colouring often found in this species.

Compared with examples of N. agatha from Natal, these specimens have the ground of a less deep black ; tbe white bands are slightly |
