ORTHARBELA. By M. Gaede. 
Mashonaland. In the same district besides, and in Cameroon apparently exclusively, a form occurs in which 
the band on the fore wing is not forked, but fills up the whole space between veins 3 and 5. Hindwing of $ 
almost white. 
jansei . M. jansei sp. n. (78 f). Similar though larger. Ground-colour more reddish brown. The upper branch 
of the white radial line is entirely absent, the branch at vein 2 feebler, below it as far as the inner margin 
considerably darker. Cross-vein slightly darkened, the exterior line sometimes indicated by some dots. Hindwing 
paler red-brown. 30 -32 mm. East Africa. Also a damaged specimen from Cameroon probably belongs to 
this species. The ^ of it shows the same colouring on both wings, the white radial line is indicated in but 
1 of 2 specimens. $ only present from the Transvaal. Janse takes this to be the normal $ of bivittata. Type <$, 
$ in the Berlin Museum.

brown sjDots parted by a pale streak in the submedian fold, and a similar one at vein 2. One spot each with a

data. Forewing with dark brown marking. Interior line represented by a short streak in the cell, behind it 2 dots 
at the upper and lower edges of the cell. A little behind the centre of the inner margin a broad band anteriorly 
as far as the cell, enclosing a white spot below vein 2. Exterior line only marked by a few dots. At the ends 
of the veins more distinct black dots. 22 mm. Adamaua. Type in the Berlin Museum. 
atbivenaia. 0. albivenata Hmps. Body brown and greyish-white. Forewing greyish redbrown, At the basal half 
of vein 1 a strong white streak, the rest and the other veins as well as the costal margin finer white. In the 
interior area at the costal margin dark streaks. Behind the cell a row of dark dots and a fine double line, 
fringe with white dots. Hindwing greyish-brown, fringe with white tips. $ 28 mm. Natal. 
rufula. 9. rufula Hmps. Body pale rusty brown. Forewing the same. A fine brown undulating interior line 
and two median lines from the cell. Exterior line more distinct, incurved below vein 7 and at vein 3. Close 
behind the cell a brown ring. Hindwing pale rusty yellow. A 26 mm. East Africa.
