78 MR. R. TRIMEN ON BUTTERFLIES [Jan. 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 ; ani 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 ex- 

 tremity 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 Grenis (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 Aryynnis. Hopffer 

 himself notices the resemblance iu size and form of the wings to the 

 female Argynnis laodice, and the likeness extends also to the black 

 markings of the upperside generally.

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. achelo'ia. 



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 ligiit coloration 

 of the underside, only one example (a male of the variety from 

 Omrora) exhibiting the deep-ferruginous colouring often found iu 

 this species. 



Genus Neptis, Fabr.

Omrora (August) and Ehanda (August-September). Eleven 

 male examples. 



Compared with examples of iV^. agatha from Natal, these specimens 

 have the ground of a less deep black ; the white bands are slightly
