A. strattipocles Oberth. (56 f) is very similar to A. igola, but lias the discal dots of the hindwing much strattipocles. 
larger and completely developed and its inner margin whitish. Madagascar. 
A. masamba Ward (56 g) closely approximates to the two preceding species, but the red-yellow scaling masamba. 
of the forewing is less extended, leaving the apex of the cell free and covering at most the base of cellule 2; 
it is much paler in the $ than in the the hindwing as in strattipocles with large discal dots; the distal black 
dot in the cell is placed more basally before the origin of vein 2; in the $ the ground-colour of the hindwing 
is often whitish. Madagascar, f. silia Mab. (56 g) only differs in having the reddish colour of the upper surface silia. 
more yellowish and behind the discal spots of the hind wing more or less whitish; the sexes almost alike. 
Madagascar, f. boseae Saalm. (56 g) is smaller, with the ground-colour of the upper surface light yellow. Mada- bo-seae. 
gascar. 
A. sambavae Ward is very similar to the last two species, but has a more brownish red colour on the sambavae. 
upper surface and differs especially in having the marginal band of the hindwing replaced by large black spots 
at the extremities of the veins; these spots touch one another at the distal margin, but are otherwise quite 
free; the inner margin of the hindwing broadly whitish yellow. Madagascar. 
A. aubyni Eltr. (60a). Basal part of the forewing above reddish; the red colour covers the cell to its aubyni. 
apex, cellules 1 a to 2 almost to the distal margin and the base of cellule 3; the apical part is blackish with 
three short whitish transparent spots in 4 to 6. Hindwing above light red nearly to the base with free black 
dots and a sharply defined black marginal band 2 mm. in breadth; beneath light ochre-yellowish, at the distal 
margin with short, fine streaks on the folds, which do not quite reach the margin. British East Africa. 
A. conradti Oberth. (56 f) differs from all the preceding similarly coloured and marked species in having conradti. 
the apical half of the forewing densely scaled without vitreous spot in 3 but with sharply defined white 
spots in 4 to 6 and especially in having the veins of the hindwing beneath broadly black at the distal margin 
and the streaks short and thickened, coniform. Nyassaland and German East Africa. 
Fifth Subgroup. 
Large species, characterized by the entire absence of the black dots in cellules 5 to 7 of the hindwing. Cellules 5 and 6 
are occasionally without dots also in the species of the preceding subgroups, but these have always 1 or 2 black dots in cellule 7. 
The forewing is at least for the most part diaphanous, at the apex and distal margin often more or less darkened, and has two, 
sometimes very indistinct, dark t rang verse bands, the first running from the costal margin through the cell to vein 1 a 
near the hinder angle and the second beyond the cell from the costal margin to vein 3 and sometimes united with the broadly 
darkened discocellulars. Hindwing with basal dots in la to lc, two dots in the cell and discal dots in 1 b to 3 and occasionally 
also in 4, that in 3 placed much nearer to the distal margin than the others. 
A. vesperalis Smith (56 f). Fore wing broadly darkened at the apex and distal margin, semitransparent vesperatis. 
and with distinct dark transverse bands. Hind wing above light ochre-yellow with black-brown marginal band 
about 4 mm. in breadth, beneath dark ochre-yellow with long dark streaks on the interneural folds. Sierra 
Leone to the Congo and Uganda. — catori Beth. Baker. Ground-colour of the hindwing light yellow. Sierra catori. 
Leone. 
A. pentapolis has the hindwing hyaline or transparent at the costal margin, in cellules 5 to 7 as far as the 
cell and in lc to 4 at the distal margin; thus only the cell, cellules la to 2 nearly to the distal margin and the 
base of cellule 3 (and 4) are scaled; the marginal streaks are often only distinct in cellules 1 c to 3. Larva dark 
umber-brown above with a white spot at each side on segments 4 to 12; head red-brown. Spines black, the 
one on segment 2 elongated. Pupa whitish with black markings; abdomen dorsally with shoit, obtuse elevations. 
— pentapolis Ward (56 e). Transverse band of the fore wing dull and little distinct; scaling of the hind wing pentapolis. 
very thin, pale yellow to whitish. Sierra Leone to the Congo and Uganda, ab. thelestis Oberth. (56 f). Sea- thelestis. 
ling of the hindwing red-yellow. Among the type-form. -—- epidica Oberth. (56 f). Transverse band of the fore- epidica. 
wing deep black and sharply defined, often much widened; scaling of the hindwing lemon-yellow; distal 
margin of both wings often broadly darkened. German East Africa. 
Sixth Subgroup. 
In the distinct free basal and discal dots of the forewing the species which belong here differ from all the others 
in the first group and consequently agree with most of those of the second. The three species are very distinct and can 
be easily separated by the characters given in the following synopsis. 
Synopsis of the Species. 
I. Both wings without submarginal dots. Discal dot 1 b of the fore wing is placed obliquely distad to 
discal dot 2.
