Review of the $ $. 
The $$ differ from the AS by both wings above being blackish-brown with yellow discal spots and 
1 or 2 yellow spots in the apex of the discal cell of the forewing. 
A. The double spot in the discal cell of the forewing and the discal spot 2 or 3 of the forewing touch each 
other (only separated by the dark median vein). Forewing above without discal spots in 1 a (4), 5 (and 8). 
a. Larger species, about 31 mm. 
*. Hindwing beneath in the basal part very much darkened, brown or greenish brown. 0. laronia. 
**. Hindwing beneath in the basal part light yellow. O. thorn. 
(3. Smaller species, 25 to 28 mm. 
*. The discal spot 3 of the forewing is distinctly triangular and entirely covers the base of the area 3. 
0. adon. 
O. chrysauge. 
0. adosus. 
0. banghaasi. 
O. distinctu-s. 
O. thops *). 
**. The discal spot 3 of the forewing is shortened towards the base and does not cover the base of the 
area 3. 0. costatus. 
B. The double spot in the discal cell of the forewing is completely separated from the discal spots by the black 
ground-colour. 
a. Forewing above with a yellow longitudinal streak in l a, but without a discal spot in 4. The discal spots 
of the hindwing above are large and long. 0. lux. 
[3. Forewing above in 1 a not marked, but with discal spots in 4 to 6. The discal spots of the hindwing 
above are small, punctiform. 0 . staudingeri. 
As nearly all the species of this genus are figured and described in the reviews of the species, I confine 
myself to statements about their geographical range. All of them belong to the region of the West African 
tropical primeval forests. 
0. laronia Hew. (77 f). Gold Coast to Gabun, Ituri and Ruwenzori. 
0. thora Plotz (77 f). ,,Guinea“. Gabun. 
0. adon Mab. (77 g). Sierra Leone to Gabun. 
0. chrysauge Mab. (77 g). Nigeria: Loko. Cameroon. 
0. adosus Mab. (77 h). Sierra Leone to Gabun. 
0. thops Roll. (77 h). Togo. Gabun. 
0. distinctus Holl. (77 h). Gabun. 
0. banghaasi Holl. (77 h). French Congo. 
0. lux Holl. (77 g). 0 gowe Valley; Belgian Congo. 
0. costatus Auriv. {= cottoni B.-Bak.). The $ differs from all the other species by the forewing 
above being brown as far as the fine marginal line, with black veins and yellowish-brown discal spots distally 
indistinctly defined, and a similar small spot in the discal cell; jet-black are only an oblong spot in the cell, 
a triangular spot behind the cell-end in (3), 4 and 5, and a transverse spot at the posterior margin behind 
the centre of the areas 1 a and 1 b. Hind wing above at the base and at the hind-margin black, in 
the marginal half deep yellow with a fine dark marginal line. The $ differs but little from the °f the 
other species. Cameroon and Congo District. 
0. staudingeri Holl. (77 g). Of this species only the $ is known, and it is not quite certain whether 
it belongs to the genus Osmodes. Ogowe Valley. 
24. Genus: ISlialHloiBiaBifis Holl. 
This genus differs but little from Osmode.s, but it has a different marking of both wings. Only one species. 
$. Forewing beneath without a hair-pencil at the posterior margin. 
Rh. galatia Hew. (= rhabdophorus Mab.) {11 h $) is easily recognizable in the $ by the figure. 
The B occurs in two forms; in both the forms the hindwing above is yellowish-brown, and at the costal margin 
* The differences of the ?? of these six species are insignificant and not yet clear to me.
