with narrow grey rings. Antennae light yellow. Porewing above blackish-grey with two short white streaks 
at the base, an indistinct white, black-curled spot at the apex of the discal cell, and a dentate black oblique 
line from the apex of the wing to the anal margin beyond the centre; this line is towards the base broadly 
bordered with white between the apex and the vein 5 or 4; marginal area speckled with whitish scales; fringes 
grey, at the ends of the veins blackish. Hindwing whitish or light grey, at the margin and anal angle more 
or less darkened. Expanse of wings: 23 mm. Cape Colony: Kimberley. South West Africa. 
I append here the two following species, the position of which is uncertain, because the descriptions 
do not mention anything about the marking of the tarsi. 
sabrina. B. sabrina Drc. (30 e). Head white, antennae yellow; palpi yellowish-white; collar and thorax light 
brown; tegulae light brown, margined with white; abdomen and legs white. Eorewing pale brown with two 
white longitudinal stripes extending from the base of the wing almost to the distal margin; the first is straight, 
the other one bent up towards the apex of the wing; the costal margin and fringes are white. Hindwing yellowish- 
white. Somali Land. 
fulvostriata. B. fulvostriata Pag. „<$. Antennae light brown, frons and collar white, chest white with a brownish 
tint, abdomen the same. Forewing white with two parallel curved brownish transverse lines from the apex 
towards the ground. Subcostal veins scaled brownish. Hindwing whitish with a dark marginal line. Forewing 
beneath white. Costal veins brownish, transverse lines indistinct. Hindwing of a pure white. Expanse of 
wings: 25 mm.“ Somaliland. — It may be a form of B. sabrina ? 
9. Genus: 4)*lontoc*lieiIoptei*yx Wallgr. 
The species belonging to this genus are also externally easily recognisable by the scale-dents at the 
anal margin of the forewing. Frons long-haired, unarmed. Palpi long, obliquely bent up, projecting beyond 
the frons, at the apex very broad and densely haired. Antennae of $ with long, of $ with short pinnae. Eyes 
hairy. Legs, also the tarsi above, long-haired. Forewing with an almost straight costal margin, a uniform, 
rather strongly bent distal margin, and a very short anal margin (from the base to the apex of vein 1). Veins 
4 and 5 from the same place or on a very short fork, 8 from the fork of 6 and 7, 9 and 10 on a very long 
fork, 9 into the distal margin. Hindwing at the costal margin slightly concave, its veins 4 and 5 forked. Distal 
margin in both wings almost entire; fringes, however, feebly undulate. 
myxa. 0. myxa Wallengr. (30 e). <$. Head and anterior dorsum white or light grey, posterior dorsum darkened 
by brownish. Abdomen above whitish yellow, often in the middle ochreous-yellow, at the base and apex dark 
brown. Forewing with light veins, a white discal spot and small black submarginal dots in 2 to 9, of which, 
however, one or several may be absent; the variegated and somewhat confused other marking is best seen 
from the figure. Forewing beneath similar, but only indistinctly marked, with light veins. Hindwing whitish 
without markings. The $ is larger with broader wings and a lighter ground-colour. Hindwing like in the $ 
uni-coloured white or greyish-white. Thorax and abdomen uni-colourecl white or whitish. Natal to Kilima- 
obscura. Njaro. — obscura form. nov. differs from the typical form in the darker colouring of the forewing, the fringes 
being speckled with blackish-brown between the ends of the veins, and a darker hindwing. The latter is in 
the G dark grey with a bent blackish median transverse band getting much broader towards the hind-margin 
and below sharply defined, whereas the $ hindwing is greyish-yellow with two similar, dull grey bands. Natal. 
maculata. 0. maculata Auriv. (31 a). The forewing is (vid. figure) in this species much less variegated, more 
monotonously coloured and marked brown; the black sub marginal dots are all present and situate on the 
inside of a small white spot. Adamaua. 
10. Genus: Oploineta Auriv. 
Forewing in the $ very long and narrow with a short anal margin, an almost straight distal margin, 
and a straight costal margin being only slightly bent before the apex. Palpi rather long, thick. Head and thorax 
densely haired. Frons armed with a long spine. Forewing: veins 4 and 5 rise from the same place, 6 and 7 
on a short fork, 8 separately from the apex of the discal cell, 9 and 10 three times the length of their pedicle, 
9 into the distal margin. Hindwing: veins 4 and 5 from the posterior angle of the discal cell; basal cell small, 
not half the length of the discal cell, veins 7 and 8 united in one place. Posterior body extended coni¬ 
form, much longer than the hindwing. 
comuta. 0. comuta Auriv. (30 f). Head and anterior dorsum blackish-brown; metathorax brown. Abdomen 
above blackish. Body beneath yellowish-brown. Forewing dark brown, in the marginal portion lighter brown, 
before the margin (in the areas 1 b to 9) with a series of black angular markings. Hindwing small and short, 
almost black, at the costal margin and distal margin brightened up by yellowish. Wings beneath almost as
