palpus and in having the spots of the forewing quite differently developed. The spots of the forewing bright 
yellow; that in 4 is placed with its outer end almost as near to the distal margin as the same spot in johnstoni, 
but is proximally long-produced and broadly united with the spot in 5; in addition the spot in 1 b is joined to 
the one in 2 and similar spots usually occur in 3 and 1 a also; hence all the light spots of the fore wing are uni¬ 
ted into a yellow transverse band, which is placed behind the cell, leaves the base of cellules 2—6 free, extends 
from the posterior to the costal margin and has distally two large excisions (in 1 b and 4); basal part of the fore¬ 
wing bright red-brown as far as the transverse band, at the base more or less blackish. Basal area of the 
hindwing white, yellowish or reddish; marginal band broad. German East Africa and Toro. 
A. oreas E. Sharpe (57 c). Both wings deep black above, with yellow markings; the forewing spotted 
quite as in fallax and confusa, but in addition with a similar spot in the cell; the hindwing with a long but nar¬ 
row median area, Avhicli covers the cell and the base of cellules 2—7, but is proximally bounded by vein 
2, thus not nearly reaching the inner margin; the fore wing is somewhat longer and narrower than in johnstoni 
and lycoa. On the under surface the hindwing and the apical part of the forewing have a rust-brown ground¬ 
colour with black longitudinal streaks; the light markings almost as above, but the yellow median area of the 
hindwing emits a branch to or almost to the middle of the inner margin. Angola; German and British East 
Africa; Uganda, ab. albimaculata Neave. Spots of the forewing white. In the same localities as the type- 
form. f. angolana Lathy. Marginal band of the hindwing beneath and apical part of the forewing with grey- 
yellow ground-colour; spots of the forewing white. Angola. $-ab. radians ah. nov. (= angolana $-ab. Lathy) 
only differs from angolana in the yellow median area of the hindwing above extending in broad rays between 
the veins nearly to the distal margin; the spots on the upperside of the forewing yellowish. Angola. 
Third Subgroup. 
Here belongs only a single little known and very distinct species, whose affinities are uncertain. In tbe position 
of the light spots in cellules 1 b and 4 of the forewing it most nearly approaches the second subgroup. 
A. insularis E. Sharpe. Forewing above black-brown with a yellow transverse spot in the middle of 
the cell and a similar orange-yellow spot at its apex, an orange-yellow spot in the basal part of 2, a free, cres¬ 
centic, small spot in 1 b near the distal margin and three small orange-yellow subapical spots in 4—6, 
of which the one in 4 is placed nearer to the distal margin and quite free. The hind wing above at the base 
blackish as far as vein 2, then with a broad median band about 5 mm. in breadth, at the inner margin and 
towards the base light yellow, distally orange-yellow, projecting almost rectangularly distad in cellule 4 (al¬ 
most as in johnstoni) and adorned with black discal dots; the hindwing beneath light yellowish to the base 
with free black dots and beyond the middle with a broad blackish transverse band, which is separated 
from the distal margin by a fine light line; this light marginal line is broken up into small spots by the 
dark veins and the streaks on the internearal folds. Island of Sgo Thome. 
Fourth Subgroup. 
According to the discoveries of recent years some of the numerous species of this subgroup are very variable and can 
only with difficulty be sharply differentiated in a synopsis. In order, however, to facilitate the determination as far as possible 
I have made the attempt. 
Synopsis of the Species. 
I. Hindwing above at the base more or less broadly darkened; its black discal dots incompletely developed 
(always wanting in cellules 3 and 4) and placed near the base. 
A. The longitudinal streaks of the interneural folds on the under surface of the hindwing reach the distal 
margin and are of uniform thickness or somewhat thickened towards the distal margin, 
a. The apical part of the forewing (as far as the cell and vein 3) more or less hyaline or at least in 4—6 
with hyaline or transparent whitish or light yellowish spots. 
* Hindwing between veins 3 and 8 with a diaphanous transverse band, which covers the base 
of cellules 3—6. A. semivitrea. 
** Hindwing without diaphanous spots. 
§. Median band or median area of the hindwing sulphur-yellow to whitish yellow. 
A. servona. 
A. circeis. 
A. safie. 
§§. Median band or median area of the hind wing red to red-yellow, occasionally entirely absent. 
0. Forewing more or less densely scaled and at least with indications of light spots. Hind- 
oreos. 
albimacu- 
lata. 
angolana. 
radians. 
insularis.
