H. zaira Plotz (75 d) is only known to me by Plotz’ description and his rather bad figure which is zaira. 
copied here. The figure does not correspond with the description. The species is surely very closely allied to 
dromus, as Plotz has himself stated by the review. His description contains beside what is common to both 
species, merely the following: Hindwing beneath of a dingy greenish white with two broad olive green transverse 
bands extending from the costal margin into cell 1 c, one of which is faded brownish towards the base, the 
other towards the margin. Forewing in cell 1 b with a large white central spot, a dot below the spot of the 
cell 2, and a small spot towards the base. The upper surface as in vindexP Congo. 
H. leucomelas Oberth. Wings above black with distinctly prominent white spots. Forewing above icucomclas. 
with a basal streak in 1 b and a basal spot in the discal cell, central luna moderately large or strigiform; 
submarginal spots 4 and 5 large; fringes above in the basal half black with minute white streaks at the end 
of the folds. Hindwing above with a basal dot arid a white median band almost as in dromus and spio. Under 
surface as in dromus, but the basal area of the hindwing with but one dark spot (in 8). Expanse of wings: 
24 mm. East Africa: Mpala; Nyangao. 
H. diomus Hpffr. (75 c; bad and schematic, the colours too glaring). This and the two following diomus. 
species form a small group distinguished by the forewing above exhibiting near the posterior margin two small 
white transverse streaks being vertically placed towards the posterior margin and therefore being parallel, 
one of which is composed of the basal spots in 1 b and in the discal cell, the other of the discal spots 1 b 2 
and 2; as the spots in 1 b may often be parted by the fold, each of the two transverse streaks is often 
composed of three divisions. The light median band of the hindwing beneath commences about at the centre 
of the costal margin, it is feebly bent and therefore not so erect as in the following species. Portuguese and 
,,German” East Africa. 
H, ferax Wallengr. (= ferox Oberth.) (75 c) only differs from diomus by the light median band of ferax. 
the hindwing beneath commencing before the centre of the costal margin, being almost straight and therefore 
more erect. It is presumably only a southern race of diomus. Cape C-olony to Damara Land and Transvaal. 
H. lacreuzi Oberth. I only know from the figure. It is somewhat larger than the two preceding lacreuzi. 
species with exactly the same macular marking of the forewing. Hindwing above with a white basal dot and a 
white median band, which is composed of an isolated rounded dot in 1 c, an oblong spot in 2, a minute triangle 
in 3, a large quadrangular spot in 4 + 5, and a minute dot in 6. Hindwing beneath on a monotonous 
white ground only with the usual dark transverse bands and without dark spots or band at the margin; the 
dark transverse bands are narrow, almost broken up into spots and terminating at vein 1 h, not quite 
reaching the costal margin. Transvaal. 
H. spio L. (= vindex Or.) (75 c). This long-known species is easily discernible from all the others sjno. 
by the figure and the marks mentioned in the review. Cape Colony to Delagoa Bay, Kilimandjaro (and Angola ?). 
H. mafa Trim. (75 c) has smaller, more equally sized sub marginal dots of the forewing and a narrower mafa. 
median band more broken up into spots on the hindwing above, but otherwise it exactly corresponds with 
spio; the light median band of the hindwing beneath is sometimes, though not always, defined towards the 
light hind-margin by a dark spot at vein 1 b. Cape Colony to Transvaal. 
H. adenensis Btlr. is above similar to the two preceding species, but on the hindwing beneath different adenensis. 
from all the other species dealt with here by being of a monotonous dark grey except the whitish spotless hind- 
margin (in 1 a and 1 b), with sharply defined whitish spots, 3 in the basal area, 3 right across the centre, and 
some smaller marginal ones. Arabia: Aden. — According to Rebel, it is merely a race of the Indian H. 
gcilba F. (Vol. IX, pi. 165 i). 
H. oberthiiri sp. nov. (= transvaaliae Oberth.) I denominate a small species which was figured by oberthiiri. 
Oberthur as transvaaliae and is otherwise unknown to me, but which can evidently not be the same species 
as Trimen’s transvaaliae. According to the figure, oberthiiri exactly corresponds above with H. mafa, except 
that the basal spot in area 1 b of the forewing seems to be absent. The under surface of the fore wing is also 
hardly different, but there seem to be small discal spots in 4 and 5. The hindwing, however, is beneath quite 
different, being everywhere also as far as the hind-margin of an almost monotonous light greyish brown, 
without distinct dark transverse bands and without any other markings but two rounded whitish discal spots, 
one in 4 + 5 and the other in 6 + 7. Kimberley. 
H. sandaster Trim. (75 c) differs considerably from the other species by the under surface of the hindwing sandasicr. 
and is therefore easily recognizable by the description in the review and the unfortunately very mediocre 
figure. Cape Colony. —- According to Higgins, the hind tibiae show but two spurs, and it may belong to 
another genus.
