138 OTHROEDA. By Dr. M. Hering. 
0. simplex Wkr. Pale yellowish; antennae, tibiae, and tarsi black. Forewing coloured like the body, 
with a black costal margin. Expanse 64 mm. South Africa. 
0. fuscovenata Wichgr. Smaller and more yellowish than the preceding species, costal margin yellowish, 
veins distally brown. Expanse 27 mm. German East Africa. 
0. oberthueri JRothsch. A gigantic species. Body yellowish-white, the anal portion of the abdomen 
cinnamon-brown. Wings diaphanous brownish, forewing with an angular median band, hindwing with a convex 
post median band. Expanse 135 mm. Comoro Is. 
0. neavei Rothsch. Body orange, abdomen black; 3 basal joints and the last joint orange. Forewing 
dark smoky grey, the central and most distal quarters of the costal-marginal area orange, internerval spots 
in the basal 2 / 5 suffused with orange, in the distal 3 / 5 only bordered with orange. An oval orange spot between 
the veins 2 and 3 below the cell. Hindwing orange, with a black spot at the cell-end and a black submarginal 
band, and black veins beyond the latter. Expanse 95 mm. Nyassalancl. 
25. Genus: Otl»roe«l» Hbn. 
Hind tibiae with 2 pair of spurs, palpi projecting beyond the head. Forewing without an accessory 
cell, 11 from the cell, 7, 10, 9 and 8 forked in this order; in the hindwing all the veins rise from the cell, 
vein 4 nearer to 5 than to 3. — The species vary exceedingly and are only to be ascertained by the sexual 
appendages. -Jordan undertook a thorough revision in 1924, so that this genus can be regarded now as being 
well explored. 
0. nerina Drc. (= $ occidentis Wkr.) (19 d) is the darkest species; the longitudinal stripes in 
the basal area of the forewing in the Jj very narrow, the light area of the hindwing dark grey, abundantly powdered 
with oclireous-yellow, otherwise similar to N. vesperina jonesi f. fumosa Jord. The $ is separated from similar 
forms likewise by narrow longitudinal stripes in the basal area. The proximal margin of the distal band in 
the hindwing cuts veins 6 and 7 close at their base. Sierra Leone, Gold Coast. The 8th tergit of the (J 
is at the end feebly bent downward, in the $ the anterior border of the vaginal opening in the centre with 
a lobate projection. 
0. planax Jord. (= ? eremitana Strd.) (19 d, e). The black distal margin of the hindwing cuts about 
the centre of veins 6 and 7 proximally, the species being otherwise very variable; hindwing whitish, powdered 
with yellowish or blackish. In the form albida Jord. the hindwing (<$ and $) is white, before the black marginal 
band orange-yellow; in the J form fumosa Jord. the hindwing is powdered with blackish in the light area; then 
the species is externally not separable from vesperina jonesi f. fumosa. — The 8th tergit of the <§ is at the end 
straight, in the $ the anterior border of the vaginal orifice is similar as in nerina though flatter. Gold Coast 
to Congo. 
0= hesperia Cr. (19 d) is a light form, never dark-powdered on the bands of the forewing or in the 
hindwing. The black margin of the hindwing, which in planax albida goes proximally through the centre of veins 
6 and 7, cuts the veins here before the centre. The 8th tergit in the $ is posteriorly long and bent upward, 
in the $ the anterior border of the vaginal orifice shows in the centre a deep acute-angled indentation. Sierra 
Leone and Gold Coast. 
0. vesperina Wkr. (19 e) is an uncommonly variable species. In the genuine vesperina (— varunaea 
Drc.) all the white markings except the subapical spots are orange-yellow, the base of the forewing has black 
longitudinal stripes (Congo and Loanda) which are absent in tenuimargo Prout (19 f) (Angola, Lualaba, L. 
Tanganyika). The light specimens are difficult to separate externally from planax and hesperia ; they belong 
to jonesi Sharpe (19 e) in which the hindwing may be likewise almost white, as in the form albida Jord., or they 
are for the greatest part powdered with blackish: = fumosa Jord. Between the two extreme forms all kinds of 
transitions occur. Lagos to Gabun. The 8th tergit-appendage in the $ is broader, at the end broadly rounded. 
The strangulation of the anterior border of the $ vaginal orifice is similar to that of hesperia , but flatter and 
wider. 
0. manifesta Swh. Similar to jonesi f. albida, but yellowish-white, the 1st subapical spot of the forewing 
sometimes larger and not so far basally removed. Hindwing without orange. Genitals as in vesperina, the 
end of the 8th tergit less rounded. Congo. 
0. papilionaris Jord. (19 f). Wings pale orange with a black distal margin containing white spots, 
and two black spots at the costal margin of the forewing. Congo, Lualaba-Kassai. 
0. permagnifica Holl. Wings of a deeper orange-red colour, the black marginal band of the forewing 
broader than in papilionaris , reaching to the cell-end, in its proximal part a row of white spots, which is sometimes 
absent; in the submarginal row of white spots the fourth is the largest; an admarginal row of small double spots. 
Ogove, Cameroon. 
0. cafra Drc. (19 f). Forewing white with a brown hindmarginal streak, 3 slanting cross-bands, the 
distal one of which is very broad at the costa and fills up the apex, therein 2 white spots; some black and
