is sometimes bordered by an undulate black line extending from the lower cell-angle to the inner margin. Ex¬ 
terior line white, dord^le, slightly concave behind the cell and in the sid>median fold, a narrow black stripe be¬ 
hind it between veins 7 and 4. Submarginal line intensely white, introangular behind the cell, terminating 
into a faded white sjjot at the inner margin. Hindwing orange, brown at the apex, with a brown band at the 
margin or before it. 20—22 mm. South and South-West Africa. 
0. subterminalis Hptps. (14e). Body and forewing dark reddish brown. Interior line double, white, 
almost straight, similar as in heliasiis. Ring-macida and reniform macula normal, strangulated in the middle, 
oblique. Exterior line, according to the original figure, white, dentate, rather uniformly bent. The light sub¬ 
marginal line is slightly excurved in the centre of the wdng. Hindwing orange, broadly brownish at the costal 
margin, narrower before the inner margin. The dark sid^marginal band is rather far from the margin, an apical 
spot behind it. This band is more or less interrupted in the with streaks behind it as far as the apex. 
20—24 mm. South Africa. 
0. chionoperas Hmps. Forewing dull red-brown. Interior line indistinct, dark, strongly excurved in 
the sidjinedian fold, less so below the costal margin, edged, somewhat yellow outside. Two yellow dots in the 
middle of the cell. Reniform macxda edged yellowisli, small. Exterior line blackish, edged ochreous outside, 
excurved beloAV the costal margin, incurved at vein 5. Sidxmarginal line blackislx, undulate, indistinct, rvith 
white spots outside, the margin itself somewliat yellowish. Fringe white at the apex, hindwing orange. Brownish 
at the costal margin, in the .submedian fold and at the inner margin at the base. A black spot at the cross-vein, 
a submarginal streak at the co.stal margin. 22 mm. Transvaal. 
0. apicalis Hvips. (14e). Similar to varia . Interior line slightly excurved in the middle. Ring-macula 
composed of 2 white dots. Reniform macida edged white, straightly exit off below, narrow. Exterior line white, 
doxxble, with a sharp inward point Ixehind the cell, incxirved in the sxilxmedian fold, with an oxitward point at 
vein 1. Sxdxmarginal line white, likewise with an inward point behind the cell, otheinvise xxndxilate, a lighter 
band befoi’e it with sevei’al long inwxxrd notches. Fringe somewhat white at the apex. Hindwing orange with 
short dark radial stripes at the base, the margin blackish-brown, broader at the apex, also with a black central 
spot or a narrow submarginal band. 18—20 mm. East Africa, Rhodesia. 
0. divisa Gaede (14e). Fxxrewing light brown as far as the interior line wdiich is double, white, extra- 
angular below the costal ixiargin, then straight to the inner margin, a yellowish spot behinxl it in the cell. Ex¬ 
terior line doxxble, white, edged Ixlack outside in the anterior part, extending aloixg the white-edged reniform 
macxxla, with an obtxxse inwai'd angle behinxl the cell, bent inwards in the sxxbniedian fold. Sxxbmarginal line 
very indistinctly white, irregxilarly notched, Ixlackish before it as far as the exterior line and vein 4, the margin 
Ixehind it also blackish. Hindwing brownish, with an orange nxedian band which is parted by a brown line. 
18 jnm. East Africa. 
0. binorbis Hm.ps. Forewing jxxst as dark and as indi.stiixctly marked as in divisa. The two macxxlae 
very indistinct, the dark interior and exterior lines similar to divisa. Only the exterior jxart of the median area 
as far as the exterior line is dark. According to the figxu'e Ixy Hampson, the exterior line is black oxxtside on 
its whole length. Hindwing somewhat more different from divisa, oi'ange, sonxewhat brownish. A dark ex¬ 
terior line and a broader sxxbmarginal band which is dentate oxxtside. — Ixi dissotuta Strd. the exterior lixxe is 
absent axid the sxxbmarginal baxxd coxxsists oxily of streaks. 3(1 ixixn. Traxxsvaal. 
0. bisexualis Hmps. (14f). Forewing dai’k, soxnewhat oraxige at the base. Interior line doxxble, filled 
with oraxxge in froxit, xxxidxxlate. Riixg-nxacxila of yelloAV dots, reixiforxn macxxla edged yellow, oxxtwxirdly pro- 
loxxged below. A dark nxedian shadow froixx the lower cell-axigle to the inixer xixargixx. Exterior lixxe also filled 
Avith yelloAv at the costal margin, shaped as ixx divisa, the yellowdsh sxxbixxargiixal lixxe the saxxxe. HiixclAvixxg oraxxge,

line as in bisexualis, but not filled light. Dark behind it as far as vein 4. 8ubnxarginal lixxe Avhitish, undulate,
