brownisli disco-cellular spot ; a dark mark on costa, beyond middle, 
commences an indistinct, transverse, angulated row of brownisli spots. 
Variety A. ($ and — $ not differing on upper side ; $ with 
the black markings usually more or less reduced, and with the apical 
patch of the fore-wing outwardly much suffused with dull-rusty 
brownish. Under side. — Hind-iuing and apical area of fore-wing, in 
loth sexes, pale dull creamy-reddish. 
{Hah. — Eastern Districts of Cape Colony, Natal, Transvaal, and 
Eastern South-Tropical Interior.) ^ 
Examples intermediate between the variety and typical Eris occur, 
more particularly in the in which the under side presents some paler 
or more decided tinge of reddish. The most pronounced of these are 
three unusually small specimens, two ^ s and a brought from Damara- 
land by the late Mr. C. J. Andersson {exp. al. $ i in. 7-^ lin. and 
8-|- lin. respectively; $ i in. lin.), but rather larger examples taken 
by Mr. A. W. Eriksson in the North-West Transvaal are almost as 
decidedly tinged, and so are two $ s from the Albany district of the 
Cape Colony, and one from the Trans-Kei territory. Three $ s cap- 
tured by Mr. John L. Fry on the Makloutse Eiver, North Bamang- 
wato country, on the 20th May 1887, differently tinted beneath, 
one being slightly yellowish, another slightly tinged with reddish- 
brown, and the third dull brownish-creamy. The last mentioned has 
much the darkest under-side that I have seen in this species. 
As will be seen from the above description, Eris is a decidedly 
variable species in both sexes, but especially in the The Dongolan 
type, as figured by Klug,^ is a ^ having the black longitudinal bands 
broader than in any South- African examples that I have seen ; the 
band of the fore-wings leaving no trace of the white spot close to 
hind-margin between second and third median nervules, and that of 
the hind- wings at its extremity projecting downward very considerably 
beyond second subcostal nervule. The fore-wing band in South- African 
specimens usually leaves, besides the white spot just mentioned ^ (which 
is, however, very small in some Transvaal examples and a Delagoa 
Bay specimen, and is only just perceptible in one from Natal), two 
more or less apparent white marks on the hind-margin between the 
spot in question and the posterior angle ; but these vary to a mere 
^ A^of the variety from Grahamstown is labelled in the British Museum collection 
(September 1886) " Johnstoni, Butler;" but I am not aware that any description of it 
has been published. 
^ Reiche {op. cii.) figures an Abyssinian £ very like Klug's, but with the apical patch of 
the fore- wings darker and of a redder tinge, and a $ rather yellowish on the upper side 
and inclining to argillaceous on the under side. 
^ After examining the Angolan specimens of Mr. Kirby's Maimuna in the British 
Museum, and carefully considering his description {loc. cit.), I am unable to regard his new 
species as a recognisable one. The $ in the British Museum has the white spot in the 
hind-marginal border of tlie fore-wings well marked, and, like the ? , agrees with the 
majority of South-African examples. The same remark applies to a c? and ? in the same 
collection from Victoria Nyanza, referred to Maimuna by Mr. A, G, Butler {Ann. and 
Mag. Nat. Hist., xii. p. loi, 1883).
