of some new Butterflies from Tropical Africa. 79 
Under-side: ground-colour pale yellowish, merging to rich orange- 
buff all over the cell of the fore-wing ; an apical and outer-marginal 
border common to both wings, composed of large A-shaped black 
markings placed between the nervules, Fore-wing: a black spot at 
the end of, and two smaller ones in, the cell. The white band of 
the upper-side is reproduced and is inwardly bordered by a distinct 
black irregular patch. Hind-wing: the basal area, which is dusted 
with blackish scales, contains about ten distinct black spots which 
are irregularly distributed and which are individually ringed with 
pale yellow. 
Head, thorax and abdomen blackish-brown above, yellowish 
below. Legs black with white spots. Antenne black above, white- 
spotted below. Cilia of fore-wing black, white between the nervules 
on hind-wing on both surfaces. 
Expanse 2 inch. 
Hab. NicEertA. Type, Mus. Druce. 
This insect is perhaps most nearly allied to Mimacrea 
gelinia, Oberthur,* described from Usambara, but bas many 
points of distinction. It is also allied to JZ. poultoni, Neave,+ 
to which it bears considerable resemblance on the under- 
side, but it has the subapical band on the fore-wing white 
and differently placed. 
Mimacrea neokoton, sp. nov. (Plate II, fig. 4.) 
Q. Allied to the preceding species but the orange area on the 
upper-side is slightly more extensive and paler; the band crossing 
the fore-wing is pale orange (excepting the first spot on the costa, 
which is white) and differently placed and the black streak in the 
cell is absent. On the under-side the A-shaped marginal markings 
are smaller and less prominent, those at the apex of the fore-wing 
being absent, whilst the nervules between which they are wanting 
are faintly blackish as also are those on the discal area of the hind- 
wing. There is an extra black spot at the junction of the lower 
median nervule, and the abdomen is distinctly black-spotted along 
its whole length. Cilia black at the extremities of the nervules, 
white between, on both surfaces. 
Expanse 14 inch.
