§. Hindwing on both surfaces with narrow, sharply defined, unspotted black marginal band. 
A. insignis. 
(cf. also A. kakana, p. 287.) 
§§. The marginal band of the hind wing at least beneath with light spots. 
0. The discal dots of the hindwing strigiform and united into a very irregular transverse 
band. Also the fore wing traversed by a curved blackish band from the middle of the 
costal margin to the hindmargin near the tornus. A. satis. 
00. The discal dots of the hindwing free and rounded. 
f. The basal dots of the hindwing beneath in cellules 1 a to 1 c and in the cell joined 
together and enclosing 2 to 4 light spots. Fore wing at the end of the cell with 
black transverse spot or streak. 
1. Forewing unicolorous smoke-brown, semitransparent, without spots or discal dots. 
A. camoena. 
2. Forewing in the basal part usually red-yellow and in the apical part hyaline, oc¬ 
casionally smoky, but then with hyaline subapical area and light marginal spots 
or sometimes completely scaled with red-yellow. 
a. Forewing with discal dots in 4 to 6. Marginal spots of the hindwing rounded, 
a'. Forewing at least with hyaline subapical area A. neobule. 
b\ Forewing fully scaled, red-yellow. A. zambesina. 
b. Forewing without discal dots at least in 4 to 6. Marginal spot of the hindwing 
small, transversely placed. A. horta. 
ff. The basal dots of the hindwing beneath entirely free. 
-—. Forewing with transverse streak at the end of the cell. A. arabica. 
—. Fore wing without transverse streak at the end of the cell. 
/V Hind wing scaled or but little hyaline. 
1. Hind wing above with broad black, sharply defined marginal band, 
which encloses large circular spots of the yellow-red ground-colour. 
A. admatha. 
2. Marginal band on the hindwing above not sharply defined. 
a) Hindwing beneath with red submarginal band and whitish marginal 
spots. A. lia. 
b) Hindwing beneath without red submarginal spots. Marginal band 
on both surfaces with indistinct yellowish marginal spots. 
A. obeira. 
/y\ Hindwing hyaline except at the base and the distal margin. Forewing 
almost entirely hyaline. A. crystallina. 
(cf. p. 282.) 
b) Hindwing with large, rounded black submarginal dots, which proximally bound the red or yellowish 
marginal spots. 
*. Forewing with reddish scaling at least to the apex of the cell. A. machequena. 
**. Forewing with red or yellowish scaling only as far as vein 2. A. ranavalona. 
II. Hindwing at the distal margin only with black spots at the extremities of the veins. Discal dots 2 to 4 
of the fore wing stand in a straight line. 
a) A larger species (62 to 75 mm.); hindwing with both discal and submarginal dots. The discal dot in 1 b 
of the fore wing placed nearer to the distal margin than the one in 2. A. hova. 
b) A smaller species; hindwing without submarginal dots. The discal dot in 1 b of the forewing placed 
directly behind the one in 2. A. mahela. 
A. insignis Dist. (53 e). Forewing above scaled with red-yellow to the apex of the cell and the hinder 
angle, in the apical part transparent black-grey, at the end of the cell with a black transverse streak, other¬ 
wise without markings. Hindwing red-yellow with narrow black, unspotted marginal band about 1 mm. in 
breadth, which beneath is often grey at the distal margin, at the base with large confluent black spots and with 
large discal dots in 1 b to 2, of which the one in 2 covers the base of the cellule, and with a thick black 
transverse streak at the end of the cell; the discal dots in cellules 3—7 are entirely absent; beneath as above, 
but much lighter reddish white with a red band at the proximal side of the black marginal band. In the $ 
the ground-colour is often grey-yellowish. ISTyassaland; German and British East Africa; Uganda, f. siginna 
Sujj. (54 a) is characterized by having the black spots in the basal part of the hindwing united into a large, 
deep black patch, which also covers the base of celhdes 3 to 6. German and British East Africa, especially in 
the high-lying localities. 
A. satis Ward (54 a). Wings above in the $ light red-yellow or brown-yellow, in the" $ white and very 
thinly scaled. Forewing at the costal margin narrowly black, at the distal margin broadly hyaline with some
