a row of smaller spots extends to the anal margin. Hindwing black with a small yellowish-brown spot at 
the apex of the discal cell and then with a broad yellowish-brown transverse band from the anal angle almost 
to the ,,proximal margin“ (sic!; presumably costal margin?). Fringes yellow. Forewing beneath almost as 
above, but browner. Hindwing beneath red-brown with two indistinct, more reddish transverse bands between 
the costal margin and hind-margin; the surface of the wing is slightly speckled with small reddish spots. 
$ very similar to the <$, but more blackish. East Africa: Daressalaam. 
0. harona Westw. (= merops Weym.) differs from all the other species in the under surface of 
the hindwing. In the type the yellow markings of the upper surface are very extensive. Forewing above at 
the base only as far as vein 2, at the anal margin in 1 a, at the distal margin in a width of about 2 mm, 
and at the costal margin very narrowly black; besides with a black longitudinal streak in the discal cell 
and, separated from it, with a coniform black spot in 4 and 5. Hindwing above only at the margins black. 
Matabele Land; Rhodesia; East Africa. — ruso Mab. (77 e), as the figure shows, only differs by the black 
colouring above being much more extensive. It flies in the same districts as the type and is presumably a 
seasonal form of it. 
5. Genus: HViisorSiiBius Wts. 
It only differs from Oxypalpus in the apex of the forewing being more rounded off and in the <$ lacking 
the mealy spot of the hindwing. 
T. watsoni Holl. (77 f) is sufficiently characterized by the figure. Gabun. Hewitson in his collection 
mistook this species for Dalla diraspes from Rio de Janeiro. 
0. Genus: Prosopalp&is Holl. 
This genus comprises but two small black species, which I was unable to examine. The second palpal 
joint is very long porrect, with half its length projecting beyond the frons, and the third joint is also long, porrect, 
pointed and almost bare. Vein 5 of the hindwing is distinct, the veins 1 a and 1 b bent. 
P. duplex Mab. (77 i). Wings above black, beneath before the margin with one or two transverse 
rows of grey dots. Sierra Leone. 
P. debilis Plotz (77 i). ,,Blackish-brown, above quite plain, beneath all the wings exhibit a dull lilac 
central dot and close behind it a similar, bent transverse band only crossed by the- dark veins, also a fine 
marginal line of the same colour; the forewing besides below the apex with 5 submarginal dots. Antennae 
3 / the length of the forewing.“ Length of forewing: 12 mm. Cameroon. Figured from Plotz’ original figure. 
7. Genus: Acleros Mab. 
Small, closely allied and indistinctly defined species which are almost invariably recognizable by the 
long, thin and pointed terminal joint of the palpi (only in placidus this terminal joint is shorter and thicker, 
more coniform), by the abdomen being white at or before the apex, and by the white fringes of the hindwings. 
In the <$<$ the forewing above is uni-coloured black or at least with traces of grey spots, whereas in the $$ 
there generally occur 2 or 3 white or whitish discal spots in 1 b, 2 (and 3), rarely also two dots in the discal 
cell. The hindwing beneath shows a peculiar, interwoven marking consisting of striae and indistinct scaled 
spots on a lighter ground. 
Review of the Species. 
A. Forewing beneath at the posterior margin dark coloured, slate-coloured or blackish, at most with a white 
marginal spot at the posterior angle. 
a. Forewing beneath with a white marginal spot in 1 a and 1 b and before it with a whitish, dark striated 
marginal band as far as vein 6 or 7. Hindwing beneath white with black striae which are more densely 
arranged at the costal margin and in the centre from the hind-margin to vein 4. A. sparsus. 
[3. Forewing beneath without a white marginal spot at the anal angle. 
*. Hindwing beneath without a broad dark marginal band or only with darker spots. 
1. Smaller species; expanse of wings about 23 mm. Hindwing above at the margin in 1 b to 2 broadly 
white (about 2 mm). A. leucopygus.
