Median line black, finely white outside, straight, slightly removed inwai'ds below tiie cell. A black luna at the 
cross-vein, the exterior line marked by a shadow. Suhmarginal line light, indistinct, excui'ved in the middle. 
The margin behind it dark. Hindwing greyish-brown. $ 20 mm. Betcbuana Land, Xatal, Somali Land.

the median line somewhat steeper. Only a dot at the cross-vein, not a luna, in a stri])e which is but little lighter 
than the rest of the marginal area. Antemarginal line pale, rather indistinct. Hinflwing browii. The cJ ex¬ 
hibits a more distinct submarginal line with a somewhat dark interior edge, somewhat lighter behind it with 
dark spots in the indentations behind the cell and in the submedian fold. Hindwing white, somewhat red-brown 
at the apex. 21 mm. East Africa. 
0. hemimelaena Hmp.s. {= transversa Pgst.) (14 b). The figure of the species in the Cat. Br. Mus. is hcmimclae- 
quite wrong and resembles more marwitzi; in fact, the species agrees more with the figure of ochrozona limps. 
Forewing blackish-broAvn. Interior line black, indistinct, vertical. At the cross-vein an oval greenish brown spot 
with w'hitish yellow edge from which a streak branches off to the costal margin, asw'ell as the median line which 
is indented in the submedian fold. The rest of the wing is greenish browm. Submarginal line whitish yellow, 
straight, bent inwards below the middle, then to the anal angle. Hindwing orange in the basal half, wdth 
a broad blackish margin. — limbogrisea Strd. has a grey margin on the forewing. 18—22 mm. Madagascar, Umhogri-

0. semitorrida Poult. (14 c) is somewdiat like semipiirpurea. Body brownish ochreous. Forewing dark semitomda 
reddish brown as far as the exterior line, the rest reddish w'hite. Interior line traceable, its inner side wdth a streak 
from the costal margin. A white dot in the centre of the cell. Reniform jnacula ror;nd, wdiite, wdth a pale l)rown 
centre. Exterior line treble, brown, extending in the light marginal area, thickened at the costal margin, more 
excurved behind the cell. Submarginal line wdiite, edged somewdiat brown inside. Hindwdng wdiitish, lirowner 
at the margin. The dark places are much redder in the $, often almost carmine. 18—20 mm. Somali Land.

dark browm below' the cell, the rest of the wdng greyish-brown. Interior line marked by an oblique brown streak 
from the costal margin, by an undulate line from the cell to the inner margin, edged wdiite inside, wdth short 
brow'll streaks inside in the submedian fold. A brown spot in the cell-end, and a white streak at the cross¬ 
vein, a black dot above it at the costal margin. Exterior line scarcely discernible, excurved as far as vein 4. 
wdiite at the inner margin. Subniarginal line white, a dark spot behind it in the discal fold. Hindwdng brownish.

0. hemipyra Poidt. (14 c) is very similar to marwitzi in its colour and marking. An interior black line hemipyra. 
is traceable, edged red inside at the costal and inner margins, extending close at the median line which is shaped 
as in marivitzi. A black dmt behind it at the costal margin, but none at the cross-vein. Ground-colour behind 
the median line fiery red, greyer only at the margin. Exterior line marked by a shadow. Subniarginal line 
w'hitish, edged dark inside. Hindwing brownish. $ 20 mm. Somali Land.

at the costal margin. Exterior line thick, blackish-brow'ii, traversing the cross-vein, then vertical to the inner 
margin, edged w'hite outside. Submarginal line w'hitish, edged dark inside, slightly undulate. Hindwiiig whit¬ 
ish ochreous, reddish behind the lower cell-angle, brow'iiish at the margin, 18 mm. Somali Land.

marginal area except at the apex. Interior line indistinctly brow'iiish, doidile, undulate. A dark brow'n median 
shadoAV as far as the exterior line, and beyond the latter at the costal margin. It encloses the reniform macula 
w'ith a red-brow'ii centre and a wdiite margin, strangulated in the middle, a w'hite spot above it at the costal 
margin. Exterior line double, dark, incurved at the costal margin and below the cell. Submarginal line white, 
undulate, edged brow'n inside. Hindw'ing pale ochreous, brown at the margin. The $ has a more ochreous
