New or little-known African Butterflies. 13 
the entire hindwing are of a dull creamy tint slightly tinged with 
reddish, and with the various series of spots faintly marked, paler 
than ground-colour, but with darker outlines. 
This Durbania is nearly related to D. aslauga, Trim., 
but is readily distinguishable by its very much paler 
colouring and (in the male) by the very great reduction 
of the dark markings of the forewing. The females of the 
two forms are much closer as regards the latter character, 
but on the underside are strikingly dissimilar, D. aslauga 
? closely resembling the male in colouring, while D. 
pallida 2 is of extreme paleness, especially as regards the 
spots of the hindwing. 
The male and female described were taken by Mr. 
G. A. K. Marshall at Gadzima, Umfuli River, Mashunaland, 
on 28th and 31st August, 1895, respectively. 
Genus MIMACRZA. 
Mimacrea marshalli, sp. n. (PI. I, fig. 9). 
Exp. al. 1 in. 10$ lin.—2 in. Fulvous-ochreous ; apical half of 
forewing fuscous with white subapical bar; hindwing with rather 
narrow fuscous hindmarginal border. Forewing: a widening 
fuscous costal border from base, becoming merged in apical fuscous 
about middle ; confluent with this border is a terminal disco-cellular 
fuscous spot; apical fuscous area extending hindmarginally to 
posterior angle by a narrow prolongation from below 2nd median 
nervule ; subapical white bar oblique, continuous, consisting above 
subcostal nervure of three small elongate-cuneiform marks (of which 
the Ist and 2nd are situated nearer to base than the 3rd), and between 
subcostal nervure and 3rd median nervule of three much larger 
subrectangular divisions ; a faint fuscous mark on disc between 1st 
median nervule and submedian nervure; fulvous-ochreous area 
paler externally ; neuration (especially submedian nervure) black. 
Hindwing: fulvous-ochreous field much paler externally, and 
narrowly still paler along inner-margin; fuscous border com- 
mencing narrowly at apex, but widening on Ist subcostal nervule, 
thence moderately broad as far as 2nd median nervule where it 
abruptly narrows and whence it remains merely linear to anal 
angle ; a small, almost linear, terminal disco-cellular fuscous spot, 
and a larger subcostal one beyond middle ; in discoidal cell and 
beneath it the fuscous spots of the underside are faintly visible.
