a) Forewing above not darkened at the base; discal dots 2 to 4 small, rounded and placed 
in a nearly straight line. Hindwing above with regular marginal band, at most 2 mm. in 
breadth. A. hypoleuca. 
b) Forewing above darkened at the base to beyond the middle of the cell. Discal dots very 
large; those in cellules 3 to 6 united into a very broad transverse band. Marginal band 
of the hind wing above 5 to 6 mm. in breadth, irregularly defined proximall y and with 
very small white dots at the distal margin. A. turna. 
B. Cellules 3 to 5 of the hindwing without discal dots. The distal spot in the cell of the hindwing 
strigiform and angled. Hindwing on both surfaces with large light marginal spots of the ground-colour, 
only bounded by black lunules. A. aureola. 
II. Cell of the hindwing only with one black dot, which is often placed beyond the origin of vein 2. Forewing 
above usually with light marginal spots. Marginal band of the hindwing above usually light-spotted. 
A. Wings above with red-yellow to grey-yellow ground-colour. Hindwing beneath not golden yellow. 
a) Forewing above and beneath with broad white subapical band. A. wigginsi. 
b) Fore wing without white subapical band. A. anacreon. 
B. Hindwing above deep black without markings {$) or black-grey with discal dots and broad unspotted 
black marginal band, beneath glossy light golden yellow with red dots at the extremities of the mar¬ 
ginal spots. A. mirifica. 
A. aureola Eltr. (60 c) is a rare species, only one specimen (from Angola) being yet known. The wings aureola. 
are bright orange-yellow above, at the base a little darkened; forewing with a black dot in the cell, the usual 
discal dots, the one in 1 b placed very near to the distal margin and those in cellules 3 to 6 forming a shallow 
curve, and a fine dark marginal band, which is not widened at the apex; the veins at the distal margin finely 
black and somewhat widened. Hindwing above and beneath with large marginal spots, which are of the ground¬ 
colour and are bounded by black lunules; the discal dots of cellules 2 to 5 entirely absent, but there is 
a dot near to the marginal band in 6 and another in the middle of cellule 7; the underside of the hind¬ 
wing is lighter, at the base in 1 a to 1 c and the cell ochre-yellow; this basal area scarcely reaches vein 2, is 
distally bounded in the cell and 1 c by a thick black streak and encloses a black dot in the cell. 
A. onerata Trim, seems from the figure to be nearly allied to aureola and has the marginal band on the onerata. 
hindwing and the basal area on its under surface quite similar, but differs in its smaller size (expanse about 
45 mm.), in having discal spots in cellules 2, 4 and 5 of the hindwing and in the more irregularly arranged 
discal dots in cellules 3 to 6 of the fore wing. Damaraland. 
A. leucopyga Auriv. (= liszti Sujf.) (55 e). Forewing above bright orange-yellow to the base, in fresh leucopyga. 
specimens with rosy reflection; forewing above with black apical spot, 4 to 5 mm. in breadth, as far as vein 
4 and then with very fine marginal line; discal dots 3 to 6 are free and placed in a straight line, almost 
vertical to the costal margin; hindwing above with sharply defined marginal band 1 to 2 mm. in breadth and 
discal dots which are not very distinct, often only showing through from beneath. Forewing beneath without 
black spot at the apex, but here whitish yellow with orange-yellow streaks on the interneural folds; hindwing 
beneath light grey-yellow with sharply prominent black dots and reddish spots at the base and between the veins 
and dots. The rainy-season form is smaller, less brightly coloured above, with dark tinge at the base and broad¬ 
er marginal band, not sharply defined proximally, on the upperside of the hindwing. Rhodesia and Nyassaland. 
A. diogenes Stiff . (55 f) is only known in the $, but suggests a thinly scaled form of the preceding diogenes. 
species. Forewing transparent whitish grey, at the apex and distal margin broadly darkened, with discal dots 
in 1 b and 2 and occasionally also with a median dot, but with no other dots. Hindwing somewhat more 
fully scaled, above dull grey, beneath with reddish spots; marginal band and black dots almost as in leucopyga. 
Southern Congo. 
A. lofua Eltr. (60 e). <$. Wings above reddish ochre-yellow, at the base narrowly scaled with black lofua. 
and with the usual black dots; fore wing with black marginal band, which is gradually widened at the apex 
into a spot 3 mm. in breadth, beneath lighter but otherwise almost as above; hind wing above with very broad 
unspotted, deep black marginal band, which is broader in the middle, beneath with light yellow ground-colour 
and white marginal spots. The $ differs in having the forewing light ochre-yellowish without black discal 
dots and the hindwing light reddish grey-yellow; the basal and discal dots are very small and the marginal 
band somewhat narrower than in the and with grey marginal spots above also. Rhodesia, on the Lofu 
River.
