together form a black marginal band of 3% to 4 mm width enclosing large whitish or yellowish spots. North 
West Rhodesia. 
23, Genus : Spsilgis Moore. 
Frons narrow. Eyes bare. Palpi very long, porrect, thinly clad with appressed scales; terminal joint 
long. Antennae short and stout, gradually thickened towards the apex with an indistinctly defined circular 
club; the joints of the antennal shaft short, not longer than broad. Wings broad, almost entire-margined; 
hindwings without tails, at the anal angle entirely rounded off. Forewing with 11 veins; vein 9 is absent; 
vein 7 into the apex; 10 and 11 separate from the costal margin of the discal cell; vein 8 longer than 
the footstalk of 7 and 8; vein 6 separate from the apex of the discal cell. Anterior tibiae not armed. 
By the entirely rounded tailless hindwings this genus agrees with many species of the last group of 
genera, but is at once discernible from all the forms of this group by the formation of the antennae. 
Small, slender lepidoptera the wings of which show a white ground-colour, beneath decorated with 
numerous, fine, black, often irregularly extending transverse lines; margin at the ends of the veins almost 
unnoticeably indented and at least beneath dotted black. Sexes almost similar, the forewing, however, more 
triangular and more pointed. 
The laivae live on shield lice and are visited by ants. Pupae freely suspended, if seen dorsally, they 
are reported to resemble a monkey’s head. 
Review of the Species. 
A. Hindwing beneath with but feAv, 7 to 9, dark transverse lines. Forewing above without a dark anal-marginal 
band, 
a. Ground-colour of both wings white. Hindwing without a dark costal-marginal band. S. lemolea. 
[8. Ground-colour of both wings in the basal part light straw-coloured. Hindwing above at least in the 
$ with a broad blackish costal-marginal band. S. pilos. 
B. Hindwing beneath, particularly in the basal part, very densely decorated with small, dark dots and small 
transverse streaks arranged in 17 to 20 transverse rows. Forewing above also at the anal margin broadly 
darkened; the white ground-colour thus only appears in the centre of the wing. S. tintinga. 
S. lemolea Ham. Dnice (71 b). Wings white; forewing above at the base, at the costal margin, apex lemolea. 
and distal margin broadly black or blackish; liinclwing above only with small, black dots at the ends of the 
veins or also with a fine, dark marginal line; in the $ sometimes with a blackish-grey marginal band. Both 
Avings beneath with a fine marginal line being thickened at the ends of the veins and 7 or 8 more or less inter¬ 
rupted, fine, dark transverse lines evidently corresponding to the streaks proximally and distally bordering 
on the vanished spots beneath. The peculiar larva resembling a shield-louse was already in 1891 discovered 
on the OgOAve River by the American missionary A. C. Good and then described and figured by Holland 
in 1892; it lives on shield lice of the genus Dactylopius and resembles the shield-lice so much that it is difficult 
to discover it among them. The pupae are fastened on leaves and their dorsal side is said to be remarkably 
similar to a human or monkey’s face. In the whole of West Africa from Senegambia to Rhodesia and Kavirondo 
in Uganda. 
S. pilos Ham. Druce is only known in the female and only differs from lemolea by the marks men- pilos. 
tioned in the review. It may be merely a form of it. Gambia. 
S. tintinga Bsd. is smaller than the species of the continent and deviates from them particularly tintinga. 
by the marking beneath (see above). Forewing above blackish, hued someAvliat bluish, in the centre with a 
large whitish area covering the apex of the cell and the base of the areas lb to 4; the fine, black markings 
beneath diaphanous in the white area. Hindwing above white, at the base as far as the apex of the disca 
cell darkened by blackish-grey; the markings beneath diaphanous. Madagascar. 
24. Genus: Arrttgia Wallengr. 
Antennae short and robust, almost beginning from the base gradually thickened towards the apex 
(= the club commences near the base) with short joints. Palpi long, porrect, with appressed scales. Frons 
broad. Eyes bare. Anterior tibiae not armed. Anterior feet also in the $ distinctly jointed and with two ter¬ 
minal claws. Forewing with 11 veins; vein 7 into the apex of the wing; 10 and 11 separate; 6 separate from 
the apex of the discal cell.
