a) The light marginal spots proximally bordered by two short, very obliquely placed black streaks, 
which, however, do not touch in the middle. At the opening of these streaks there is usually a broad 
reddish stripe. Ground-colour of the upper surface red-yellow to brown-yellow to grey. 
A. zitja. 
b) Tlie light marginal spots on the underside of the hindwing proximally not or very indistinctly bordered 
with black. Before them are placed on the interneural folds broad orange-yellow longitudinal streaks, which 
in cellules lb to 4 are basally bounded by a black transverse line. Ground-colour of the upper surface 
sand-yellow to cream-yellow. A. rahira. 
A. althoffi Dew. (56 d) is much larger than the other species of the subgroup and differs from them all 
in the shape of the light marginal spots on the underside of the hind wing (cf. the synopsis). Fore wing 
black above with a distally widened longitudinal stripe in the cell, a subapical band and a narrow hind- 
marginal spot in cellules 1 a to 2 red in the <$, white in the the subapical band consists of 4 spots in 
cellules 3 to 6; the hindmarginal spot is about 6 mm. in breadth. The upperside of the hind wing black (A) 
or black-grey with a narrow median band, which in the A is only 3 to 4 mm. in breadth and sulphur-yel¬ 
low to whitish yellow, but in the $ 9 to 10 mm. in breadth and white. The under surface with almost the 
same markings as above but with distinct basal and discal dots on the hindwing and long black streaks in the 
distal part. Congo to Uganda. — f. rubrofasciata Auriv. differs in the red median band of the hindwing. 
Cameroons and Congo. —- §-f. telloides Eltr. is quite unlike the typical $, but bears a strong resemblance to 
Planema tell us (58 a). The basal half of the wings is dull orange-yellow nearly to the apex of the cell, the orange- 
yellow colour covering not only the greater part of cellules 1 a and 1 b and the base of cellule 2 as in PI. 
tellus, but also almost the whole of the cell; the subapical band is light ochre-yellow and consists of 4 spots, 
the one in 3, as in PI. tellus, placed nearer to the distal margin. Hindwing above dull orange-yellow to the 
base, at the distal margin with black marginal band 3 mm. in breadth, from which fine black streaks run out 
proximally on the interneural folds. Uganda. — $-ab. drucei Eltr. is similar to the typical A> only differing 
in having the longitudinal streak and the hindmarginal spot of the forewing orange-red (instead of blood-red) 
and the subapical band light yellow; the median band of the hindwing is somewhat broader than in the $ 
and white; the ground-colour of the upper surface much lighter than in the A. Uganda. — ^-ab. ochreata 
Eltr. has the light markings of the upper surface light dull ochre-yellow as in the A of joclutta (57 e). Uganda. 
- pseudepaea Dudg. is the north-western race and is distinguished from the typical A by the absence of the 
stripe in the cell of the forewing and by having the hindmarginal spot and the subapical band of the 
forewing brown-yellow and the hindwing also brown-yellow with triangular black basal area and a marginal 
band 2 mm. in breadth formed by the union of the black rays. The $ is similar to the A> but with lighter 
brown-yellow colour and almost without marginal band on the upperside of the hindwing. Ashanti and Ni¬ 
geria. 
A. oberthueri Btlr. (56 c, d) may be easily known by the numerous free basal and discal dots on the 
under surface of the hindwing. The upper surface is blackish brown-grey with the usual markings light ochre- 
yeliow; cell of the forewing without light markings; subapical band composed of three spots in cellules 4 
to 6; hindmarginal spot narrow and of almost uniform breadth, composed of spots in la, lb, 2 (and 3), 
the spot in 2 not covering the base of the cellule. Hindwing with an ochre-yellow median band, which is as 
broad as the hindmarginal spot of the fore wing and joins on to this spot; the distal part has more or less 
distinct longitudinal stripes, corresponding to those of the under surface. The distal half of the under surface 
between the veins with thick black rays, which are bifurcate at the distal margin and are separated from the 
veins by light lines. Nigeria to the Congo. In ab. confluens Suff. the subapical band of the forewing is joined 
to the hindmarginal spot in cellule 3. Among the type-form. — Larva slate-grey with red-yellow head, the 
spines of segments 2 to 5 and the upper spines of segments 10 to 13 black; those of segments 6 to 9 
and the lower ones on segments 10 to 13 yellowish; lives on one of the Tiliaceae, Ancistrocarpus densespi- 
nosus. Pupa white with two dorsal and two lateral rows of orange-yellow, black-ringed spots and black lines 
on the wing-cases. 
A. viviana Stgr. (56 c) is similar above to the preceding species and has the same light yellow markings. 
The hindmarginal spot of the forewing is, however, much broader, completely covering the base of cellule 2, 
and the median band of the hindwing is 6—8 mm. in breadth and in cellules 4 and 5 distally widened; 
the hindmarginal spot of the foreAving forms a small spot in the lower angle of the cell. The under surface 
differs in the smaller number of the black dots in the basal area of the hindwing; in the cell and in cellule 7 
these are connected by red streaks. Cameroons to Uganda and Bukoba. 
A. karschi Auriv. (56 c) is intermediate between viviana and cabira and differs from both in having the 
hindmarginal spot on the upperside of the forewing narrower, of more uniform breadth and not covering the 
base of cellule 2. The under surface of the hindwing exactly agrees with that of cabira. Is perhaps, as Eltring- 
ham thinks, only a form of cabira. Cameroons and British East Africa. 
A. rupicola A. Schultze is a species quite recently described and apparently very variable, and is 
said to differ from the allied species in having the light markings of the upper surface much reduced and not 
very sharply defined. “On the forewing the subapical band, which in all the 7 specimens before me is pale yel- 
Ioav, in one $ indistinctly dusted AA 7 ith brown-red, runs as in karschi, but is narrower; the hindmarginal spot
