II. The under surface of the wings has at least at the distal margin black transverse markings which are con¬ 
nected by the veins or is black with light spots! . 
A. Hindwing above with light markings. 
a. Forewing abo’ve with a continuous, curved, light median band. 
*. Hindwing above with a curved, light median band, running from the middle of the inner 
margin to the middle of the costal margin. 
§. The band of the forewing reaches the hindmargin or at least vein 1. Hindwing beneath 
not reticulated in the middle. 
1. The band of the forewing is posteriorly widened and covers the base of cellules 2 and 3. 
A. interposita. 
2. The band of the forewing is posteriorly not or little widened and does not cover the base 
of cellules 2 and 3. 
a. The median band of the hindwing does not reach the costal margin 
A. nyassae. 
b. The median band of the hindwing reaches the costal margin. A. rollei. 
§§. The transverse band on the upperside of the forewing has a uniform breadth of only 
1—1.5 mm. Hindwing beneath reticulated almost throughout. 
1. Both wings above with a row of white submarginal spots. A. reticulata. 
2. Wings above without light submarginal spots. A. cai.ssa. 
**. Hindwing above with a straight, narrow transverse band, composed of 5 small spots in 
cellules 1 c—5 and directed towards the apex. A. johanna. 
b. Forewing above with a white hindmarginal spot in 1 a and 1 b and a straight white subapical 
band between the costal margin and vein 3. A. picata. 
B. Hindwing above unicolorous black without markings. A. oberihueri. 
A. amazoula Bdv. (61 c). Wings red-yellow to ochre-yellow with all the veins broadly edged with black amazoula. 
and above with blackish marginal band, widened at the apex of the forewing; under surface, particularly of 
the hindwing, with lighter ground-colour and without dark marginal band. Cape to German South-West 
Africa and Nyassaland. — congoana form. nov. differs in having the ground-colour orange-yellow and the veins congoana. 
only very finely darkened. On the Lower Congo and in Angola. 
A. interposita Btlr. Wings above black-grey with a common white median band, which on the forewing interposita. 
covers the base of cellules 2 and 3; two white spots in the cell of the forewing; on the under surface the 
veins hi the distal part are connected by two black lunulate lines, which enclose two rows of light spots; 
basal area of the hindwing beneath also with large white spots. German East Africa at Tabora and on the Vic¬ 
toria Nyanza. — hauttecoeuri Oberth. (= aurantiaca Btlr.) (62 i) only differs in having the median band of both hautteeoeuri. 
w ing s orange-yellow and the marginal band narrower and above deep black. At Tabora and on Lake Tanganyika. 
A. nyassae Hew. (61 c). Wings above black-grey with narrow white median band, which on the fore- nyassae. 
wing does not cover the base of cellules 2 and 3 and is not widened towards the hindmargin and on the 
hindwing does not reach the costal margin; the dark marginal band of the upper surface is about 4 mm. 
in breadth, hence much broader than in interposita ; forewing above usually with two light subapical spots. 
On the under surface the marginal spots are often undivided and form only a macular row. Matabeleland to 
Nyassaland. ab. ochracea Btlr. The median band more or less yellowish. Nyassaland. ochracea. 
A. rollei Suff. ( = mulsa Thieme) is black with orange-yellow transverse band, which on the hindwing rollei. 
reaches the costal margin; some of the light marginal spots on the under surface are rounded and in the black 
basal area of the hindwing there are only three large light spots. German East Africa: Usambara. — According 
to Strand this is the $ of A. picata E. Sharpe. 
A. reticulata Btlr. Wings above black with white spots; forewing with two white spots in the cell, a reticulata. 
narrow, somewhat curved median band, almost broken up into spots, between the costal margin and vein 1 
and a curved row of small submarginal spots; hindwing above with curved median band, almost broken up 
into spots, and 6 free submarginal spots. Forewing beneath in the basal half black with two white spots in 
the cell and some small ones at the costal margin, in the distal half with three rows of large, only narrowly 
separated whitish yellow spots; hindwing beneath with numerous whitish yellow spots, only separated by the 
black veins and fine black transverse lines, which form an almost reticulate pattern. Nyassaland.
