and a blackish margin. 18—20 mm. South Africa, Madagascar. — centralis Pgst. is not identical with tliis 
species, as Hampson states in the Cat. Br. Mus. 
0. toxotis Hmps. (14 d). Thorax and forewing red-brown or also almost as purely brown as the hind- Ioj-oIis. 
wing. A dark double interior and exterior line is traceable only at the costal margin, filled with yellowish. 
A white dot in the middle of the cell, a white streak at the cross-vein, edged with black. The indistinct exterior 
line slightly concave behind the cell and more so in the sidnnedian fold. Submarginal line vertical from the costal 
margin to vein 5, then excurved and vertical to the anal angle, the space before it darker red.-brown. Abdomen 
and hindwing copper-brown. 22 mm. East Africa. 
0. fulvescens Hmps. (14d). Body and forewing whitish ochreous, a dark olive brown band behind fitlrescens. 
the middle and also at the distal margin but somewhat less dark. Traces of a blackish interior line. A l)lack 
streak at the cross-vein. The interior border of the dark band straight, somewhat inwards, the exterior border 
dentate, concave behind the cell and in the submedian fold. Submarginal line whitish, parallel to the margin, 
slightly excurved in the middle, olive brown before and behind it. Hindwing orange, somewhat In’ownish at 
the margin. A 20 mm. Transvaal. 
0. flavipennis Hmps. (14 d). Body and interior half of forewing greyish-brown with a reddish shine. flavipennU. 
Traces of a blackish interior line. Median line black, straight, somewhat inwards. Two black dots at the cross¬ 
vein. Exterior line black, double, filled with light, bent inwards at the costal margin, the rest ratlier straightly 
undulate. Submarginal line whitish, vertical, convex at vein 5. Hindwing greyish-brown with a darker median 
line, an orange s^Jot in the submedian fold in the centre, indistinctly defined. 24 mm. Cape Colony. 
Here follow a large series of similar species the marking of which is difficult to describe and often in¬ 
distinct. The original descriptions are mostly very long, but they do not state any differences from the other 
species and do not match exactly the figures which are sometimes indistinct. 
0. heliastis Hmps. (14 e). Forewing greyish-brown in the basal half, the rest red-brown. Interior line heUastifi. 
whitish, double, straight, somewhat inwards, and slightly extra-angnlar at the costal margin. Ring-macula 
indicated by 2 oblique white dots. Reniform macula narrow, obliquely outwards, edged white. Exterior line 
whitish, double, close at the reniform macula. Submarginal line whitish, excurved below vein 7 and in the 
middle. Fringe white at the apex as well as a little behind the cell. Hindwing dark orange, brown at the base 
and apex. The specimen figured is much darker than Hampson’s original figure, but presumably the same 
species, because the other similar ones do not exhibit the interior line so distinctly straight. 17—2d mm. South 
and East Africa. A smaller specimen (15 mm) from South-West Africa. 
0. perssoni WUgr. (= mustelina WUgr.) (14 e). Thorax and forewing very dark olive brown. Interior perssoni. 
line indistinct, double, black, somewhat dentate, outw'ards as far as the median vein, then vertical. Ring-macula 
indicated by 2 white oblique dots, in the cell and at the median vein. Reniform macula edged light, narrow, 
the lower end prolonged far outwards, a dark median shadow below it as far as the inner margin. Exterior 
line double, white, the exterior branch broad at the costal margin, obliqiiely outwards as far as vein 5, then 
sharply bent down, concave in the submedian fold, behind this place a lighter violettish-brown spot. Sub¬ 
marginal line whitish, uniformly bent, a black spot behind it at the costal margin. Fringe at the apex white 
for a short distance. Hindwing dark orange, black at the base at the costal margin. A submarginal band as 
far as the sixbmedian fold, fused at the apex with the narrow marginal band, a spot near the anal angle. Inner 
margin narrowly black. 20—22 mm. Cape Colony. 
0. acclivis Flclr. (14 c). Similar to perssoni. Ring-macula the same, reniform macula narrow, but acdhns. 
not outwardly prolonged. Interior line of forewing more bent inwards at the inner margin. A bluish-black 
spot below the reniform macula at tlie inner margin. Yellowish behind the exterior line and behind the sub¬ 
marginal line at the inner margin. Both wings beneath with numeroxis black dots, the forewing with an ex¬ 
terior line. 18—22 mm. South Africa. 
0. densa Why. (14 e) shows the interior line extra-angular below the costal margin and introangnlar densa. 
at vein 1. Ring-macula and reniform macula as in acclivis. A very undulate black line from the lower cell- 
angle to the inner margin. The exterior line somewhat concave behind the cell, bent inwards below vein 4 
and extra-angular at vein 1. Submarginal line white, with a black s])ot inside behind the cell. Hindwing similar 
to heliastis. 22—24 mm. Cape Colony. 
0. damagarina Rothsch. Similar to sancta Stgr. dealt with in Vol. 3, p. 274, pi. 51 n, but soinewhat damagari- 
darker. Forewing greyish-brown with white diffuse spots. Interior line double, black, irregvdar. A similar 
median band with a white, watchglass-like spot with 2 grey spots at the cell-end. Exterior line similar. Hind- 
wing dark orange, brownish at the base, the submarginal band interrujxted. The $ is darker on the forewing, 
reddish orange on the hindwing, the exterior third smoky brown. 15 mm. North Nigeria. 
0. varia Wkr. (14 e). Thorax and forewing reddish brown. Interior line white, double, introangidar varia. 
in the cell and in the submedian fold. The ring-macnla is a yellow dot in the cell and a w'hite one at the median 
vein. Reniform macula edged white, slightly projecting outwards below. A slightly darker shadow before it
