1. The proximal angle of cellule 2 of the fore wing completely covered by the 
light hindmarginal spot. 
a) All the markings of the upper surface yellow-red. Expanse 30 to 35 mm. 
A. uvui. 
b) All the markings of the upper surface light yellow. Expanse 48 to 50 mm. 
A. viviana. 
2. The proximal angle of cellule 2 of the forewing black. Markings of the upper 
surface light yellow. A. karschi. 
00. Eorewing above in the basal part, usually at the median vein, more or less broadly 
light. The hindmarginal spot of the forewing is irregularly defined proximally and 
is often continued along the median towards the base. 
1. The proximal angle of cellule 2 of the fore wing above completely covered by the 
light hindmarginal spot. 
a) Hindwing beneath at the base with a red streak or spot between the black 
dots at least in the cell and in cellule 8. A. cabira. 
b) Hind wing beneath at the base without red streaks between the black dots. 
A. alicia. 
2. The proximal angle of cellule 2 of the forewing above black or with a black 
dot. 
a) The red-yellow longitudinal stripe on the median of the forewing above 
is broadly and completely joined to the hindmarginal spot. 
A. bonasia. 
b) The red to red-yellow longitudinal stripe on the median of the fore wing above 
is separated from the hindmarginal spot or only narrowly and incompletely 
joined to it. A. sotikensis. 
tt- Veins 3 and 4 of the hindwing widely separated. The base of the hindwing above 
not or but very little black; the black colour does not reach vein 2. Cell of the fore wing 
above with a light spot near the apex, but otherwise black. Hindwing beneath in the 
basal area with red streaks between the black dots. 
1. Fore wing with light subapical band. A. acerata. 
2. Forewing without light subapical band. A. pullula. 
b) The cell of the forewing above entirely light or only with a black dot and at the apex somewhat 
darkened; rarely semitransparent or smoke-coloured, like cellules 1 a to 3. Veins 3 and 4 of the 
hindwing at their origin more or less broadly separated. The light (usually red-yellow) ground-colour 
of the fore wing almost entirely covers the base of cellules 1 a and 1 b. 
*. Hindwing beneath with 2 or 3 black dots in the cell, above light at the base until free black 
dots. 
1. The light marginal spots on the underside of the hindwing proximally rounded, semi¬ 
elliptical. Fore wing with broad, usually red-yellow, continuous subapical band, which is 
occasionally united with the ground-colour. 
a) Marginal band on the underside of the hindwing proximally sharply defined, uniform 
black without streaks or light dots, only with the usual marginal spots. A. lumiri. 
b) Marginal band on the underside of the hindwing in addition to the marginal spots 
with light submarginal dots or proximally very irregularly defined and deeply incised 
at each vein. A. terpsichore. 
2. The red-yellow marginal spots on the underside of the hindwing sharply triangular. The 
fore wing red-yellow as far as the apex of the cell, then black or blackish with three small 
whitish semitransparent subapical spots in 4 to 6. A. fornax. 
**. Hindwing beneath at most with one black dot in the cell. The marginal spots on the underside 
of the hindwing small, broader than long, light yellow to whitish, proximally continued by a 
long, broad red stripe edged with black. The hindwing above at the base black as far as vein 
2 and with broad, black, unspotted or indistinctly spotted marginal band. 
1. Markings of the upper surface red-yellow. A. goetzei. 
2. Subapical band of the forewing and median band of the hindwing lemon-yellow. 
A. excelsior. 
B. The discal dots on the underside of the hindwing complete, streak-like, and united into a trans¬ 
verse line, which runs from the costal to the inner margin, touches the apex of the cell and distally 
bounds the basal area. A. mirabilis. 
Fore wing in cellules 4 to 6 with free black discal dots. Discal dots 1 b to 4 or 5 of the hindwing stand 
in a nearly straight transverse line beyond the apex of the cell and discal dots 6 and 7 form almost 
a right angle with this line. The marginal spots on the underside of the hindwing whitish, broader 
than long and proximally incomplete, or not bounded by black streaks.
