A. Hindwing beneath at the distal margin in the middle of each cellule with a simple black longitudinal 
streak on the fold; occasionally at the distal margin almost diaphanous, so that the streaks are vi¬ 
sible at most in cellules 1 b and 2; forewing, however, in this case with broad dark transverse 
markings. First Group. 
B. Hindwing beneath at the distal margin without black longitudinal streaks on the folds between the 
veins. Second Group. 
II. Hindwing on both surfaces without black dots. Veins 6 and 7 of the hindwing sometimes stalked. 
Third Group. 
First Group. 
Through the black longitudinal streaks, alternating with the dark veins, at the distal margin on the underside of the 
hindwing and often also of the forewing the species of this group approach Planema in markings. Hence some species were 
formerly even incorrectly referred to Planema. On the other hand the simple light marginal spots between the veins on the 
underside of the hind wing, which occur in nearly all the species of the second group, are always entirely absent here. 
The numerous species may be divided into 6 subgroups. 
Synopsis of the Subgroups. 
I. Fore wing entirely without black basal and discal dots. Only in the of A. alciope discal dots lb—3 
are more or less well developed; this species, however, differs in the presence of a light median band 
from all the species of the sixth subgroup. 
A. Forewing black-brown with a light subapical band and a large light hindmarginal spot or crossed 
by a light transverse band, which widens towards the hindmargin. First Subgroup. 
B. Fore wing smoke-brown to blackish with light or transparent spots or sometimes almost entirely 
transparent; never with hindmarginal spot or continuous, scaled transverse band from the costal 
to the hindmargin (cf. however butleri Auriv.). 
* Cellule 7 of the hind wing at least with a black dot, never entirely diaphanous. 
1. Fore wing in cellule 4 with a light or transparent spot, placed near to the distal margin and 
nearly always (not in butleri) entirely or almost entirely separated from the spots in cellules 
5 and 6; in cellule 1 b a similar spot, placed as near to the distal margin as that in 4 and much 
nearer than the light spot in 2. 
a) Hind wing at most with one black dot in the cell and without black dots on the discocellulars. 
The light median area on the upperside of the hind wing also without black discal dots. 
Second Subgroup. 
b) Hindwing with two black dots in the cell and with black dots on the discocellulars. The light- 
median area of the hindwing with black discal dots at least in 1 b, 1 c, 3, 4 and 5. 
Third Subgroup. 
2. Cellules 4—6 of the forewing entirely or for the most part diaphanous or each with a light spot; 
these spots form a continuous subapical band and the spot in 4 is placed not or scarcely more 
distad than the one in 5. When cellule 1 b has a light spot it is not placed nearer to the 
distal margin than the one in 2. The cell of the hindwing nearly always containing two black 
dots and with black dots at its apex. Four t h Subgroup. 
** Cellules 5—7 of the hindwing always without black dots, usually diaphanous. 
Fifth Subgroup. 
II. Forewing at least in 1 b and 2 with the usual black basal and discal dots. Sixth Subgroup. 
First Subgroup. 
PlanernaAike species, which may be easily known by the hindmarginal spot of the forewing. The species are nearly 
allied and very variable; several varieties and aberrations were formerly regarded as independent species. The discocellulars 
of the hind wing without black dots. 
Synopsis of the Species. 
I. Cell of the forewing unicolorous black without light spot in the apical part. Subapical band of the fore¬ 
wing at least to vein 4 continuous and broad.
