(3. The light median band of the hindwing beneath is pointing towards the anal angle or hind-margin 
and terminates into the light hind-margin or it is directed towards it. 
*. The light median band of the hindwing beneath is not interrupted, between the costal margin 
and vein 1 b coherent, at most bordered by a dark spot in 1 c, rarely almost as dark as the ground¬ 
colour and thereby not very distinct and only marked by its exterior border-line. 
§. Forewing on both sides with discal spots in 4 and 5 or at least in 4 and often also with white 
streaks in 10 and 11. H. agylla. 
H. asterodia. 
H. machacoana. 
H. abscondita. 
§§. Forewing as usual without discal spots in the areas 4 and 5. 
+ . Forewing above without a basal spot in area 1 b. 
A . The exterior spot of the discal cell of the forewing is far remote from the central 
lima. 
o. Hindwing beneath without distinct basal spots; the median transverse 
band is often darkened brownish, but always distally bordered by a finely 
dentate dark brown or blackish line. H. secessa. 
oo. Hindwing beneath with distinct whitish basal spots on a darker ground; 
the median band is light and not distally bordered by a dark line. 
H. transvaaliae. 
A A . The exterior spot in the discal cell of the forewing is situate close at the apex 
of the cell and may even be united with the central luna. H. lcituina. 
+ +. Forewing above with a white basal spot in area 1 b. 
/V- Hindwing beneath in the basal area with some distinct dark spots and between 
them with 3 to 5 whitish spots of which that in 1 c is short, not strigiform. 
H. dromus. 
AA- Hindwing beneath in the basal area without distinct spots or only at the costal 
margin in area 8 with a dark spot. The basal area with the same ground-colour 
as the light median band. 
o. The discal spot 1 b 2 of the forewing above is absent or minute, punctiform, 
the discal spot 1 b 1 , however, large, separated from the discal spot 2 and 
situate more towards the base. H. zaira. 
H. leucomelas. 
oo. The discal spot 1 b 2 of the fore wing above is relatively large, situate exactly 
behind the discal spot 2 and sometimes parted by the fold. Discal spot 
1 b 1 , however, small and indistinct. Forewing above with two spots or 
streaks near the base of area 1 b, almost right behind the basal spot in 
the discal cell. Submarginal dots of the forewing above small and equally 
large. Hindwing beneath in the basal area whitish, without spots. 
H. diomus. 
H. ferax. 
H . lacreuzi. 
**. The light median band of the hindwing beneath is once or twice interrupted, in the former case 
forming a spot and a band, in the latter case forming three separate spots. Forewing above 
in area 1 b with a white basal spot and two almost equally large discal spots, the exterior one 
of which (= 1 b 2 ) is situate right behind the discal spot 2 with which it forms a double spot. 
§. Hindwing beneath not monotonously dark with sharply separated whitish spots; the light 
median band only interrupted in area 6 by the brown colour of the exterior transverse band. 
//. spio. 
H. mafa. 
§§. The dark ground-colour of the hindwing beneath, between the costal margin and the vein 
1 b, encloses 2 or 3 light basal spots and 3 discal spots; these are to be regarded as the 
remainders of the interrupted median band. H. adenensis. 
B. Forewing above without any white basal spots at all or at least with but one white dot or spot in 
the discal cell.
