cal dots in 1 b to 6, of which those in 1 b to 3 are placed in a straight line running parallel with the distal 
margin. The upperside of the hindwing is usually so much darkened at the base as far as the apex of the 
cell that the basal dots are not distinct, and has a broad black marginal band; beneath there are basal dots 
in 1 a to 1 c, 7 and 8 and two in the cell; the discal dots are usually present in all the cellules, but are 
irregularly arranged, the spots in 1 c and 4 being placed nearer to the base than those next to them, a black 
dot on the middle discocellular; the submarginal dots are placed just before the marginal band and occur 
in the $ in cellules 1 b to 7, in the 8 often only in 1 b to 3. -—- rogersi Hew. Black above with a trans- rogersi.

'Addendum to the First Group. 
The following quite isolated species I cite as an addendum to the first group. The underside of the 
hindwing has on the interneural folds fine indistinct black lines, which, however, do not reach the distal margin 
by some distance, at the distal margin itself they are reddish, but without forming separate marginal spots. 
On the upper surface of the hind wing, on the other hand, there are large, rounded marginal spots, distinctly 
bounded by the black veins and a submarginal line, but of exactly the same colour as the ground of the upper 
surface.

angular brown-red spots, two in 1 b, two in the cell and one in the middle of cellule 2, and in the apical 
half with three small diaphanous spots in 4 to 6. Hindwing above brown-red, in the basal part of cellules 
1 a to 2 as far as vein 3 black and with free black discal dots in (4) 5 to 7; before the distal margin 
with a thick black submarginal line, which is connected with the distal margin by the black veins; on the under 
surface the basal part as far as the discal dots and the marginal band are dull grey-brown and the interspace 
forms an anteriorly widened light grey-yellow median band; basal and discal dots all free. Ruwenzori and in 
the mountainous country at the north-west end of Lake Tanganyika. 
Second Group. 
This group embraces the majority of the Ethiopian Acraeids and may be divided into several subgroups. I have 
retained almost unaltered the subgroups of my work Rhopalocera Aethiopica, although some species have been discovered later, 
which cannot be fitted in to these without difficulty. Eltringham has erected a large number of smaller groups, which, however, 
are not characterized and hence cannot he employed here. In his key, on the other hand, he has retained the following sub¬ 
groups almost unaltered. 
Synopsis of the Subgroups. 
I. Forewing completely scaled, very rarely partially diaphanous beyond the middle with the distal margin 
spotted. Underside of the hindwing in this case with free, not confluent basal dots. 
A. Hindwing beneath at the distal margin with a light spot in each cellule, proximally dark-bordered, 
or with broad black, light-spotted marginal band. 
a) The light, often triangular or elongate marginal spots on the underside of the hindwing are bound¬ 
ed at the sides and proximally by two obliquely placed, straight or curved dark streaks proximally 
convergent or often even united, usually not joined to the black veins. When these streaks are curved, 
thickened and united with the veins, the marginal band is very similar to those of the following 
subgroups. In this case, however, the species of the present group may be known by the forewing 
being without discal dots. First Subgroup. 
(3) The light, rounded or quadrate to transverse marginal spots on the underside of the hindwing 
are bounded proximally (and at the sides) by a straight or curved, sometimes much thickened, 
transverse line. In the latter case the transverse line may be widened into a broad marginal band, 
quite enclosing the reduced spots. 
*. The basal dots on the underside of the hindwing separated. 
1. Fore wing beneath without dark streaks on the interneural folds or occasionally with short 
streaks, which, however, are far removed from the distal margin.
