Review of t h e $ 
I. Forewing without any white spots. 
A. Hindwing above with a large, jet-black mealy spot covering the discal cell and the base of the adjoining 
areas. Forewing beneath at the anal margin with a liair-pencil. S. pulvina. 
S. carbo. 
B. Hindwing above without the mealy spot. Forewing above near the base in the areas 1 b and 2 with 
a thick, but indistinct mealy spot which is parted by vein 2. Forewing without a hair-pencil beneath 
at the anal margin. S. nox. 
II. Forewing with some small white punctiform spots at least in 2, 3, and 6 . S. ilias. 
S. pulvina Plotz (79 a). Wings on both sides uni-coloured blackish-brown. In the the forewing 
beneath shows a large, somewhat silky anal-marginal spot extending to vein 3, but it is only distinctly prominent 
in a certain light and it does not reach to the margin. Sierra Leone to Gabun. 
S. carbo Mab. was already in 1896 mentioned by Holland to be identical with pulvina. Mabille, 
however, in 1903 considered it yet to be a distinct species, though he did not state any differences. The original 
description says: ,,Jet-black with a lustre. At the bases of both wings a black area with a dark blue reflection. 
Under surface black. Forewing at the base and apex dusted with yellow scales; at the anal margin a large, 
triangular spot with a silky lustre, extending into area (3) 2. A pencil of black, appressed hairs in area 1 a is 
covered by the hindwing. Hindwing dusted with lustrous scales of a red reflection. Expanse of wings: 26 mm.“ 
The description fits specimens of 8. pulvina lying before me, except that I cannot discover the mentioned red 
lustre on the hindwing beneath. 
S. atrio Mab. is on both sides entirely black, the anal margin of the forewing lighter, particularly at the 
anal angle, where it is soot-coloured. Palpi dark grey, the third joint coniform, hardly projecting. Hind tibiae 
with two pairs of spurs, clothed with stiff appressed hair. Abdomen slightly longer than the hinclwing which 
is shorter than the forewing, almost as if it were reduced. 25 mm. Cameroon. Probably the 2 of pulvina. 
§. nox Mab. (79 a). Uni-coloured black. The <$ is easily recognizable by the marks mentioned above. 
Nigeria to Gabun. 
S. corvina Mab. is probably the $ of nox. ,, Jet-black, in the centre of the hindwing soot-coloured. 
Forewing beneath black, the areas 1 a and 1 b in their whole length whitish-grey. Fringes and abdomen black. 
Prothorax with dark grey hair. Expanse of wings: 22 mm.“ Sierra Leone. 
S. ilias Plotz (78 h) was hitherto placed to the genus Parnara. The antennae, however, as the figure 
shows, are longer than in the said genus with a slender club, whit is bent outwards and gradually passes over 
into the long point, entirely as in Semalea. <$. Both wings above blackish-brown; forewing with small white 
discal dots in 2, 3, 6 and sometimes also in 7, beneath at the anal margin lighter grey, otherwise as above. 
Hindwing on both sides uni-coloured blackish-brown. The $ besides shows a small white dot in the discal cell 
of the forewing and generally also a subapical dot in 8. Cameroon; Gabun. 
10. Genus: Artitropa 11 oil 
Tip of antennal club moderately long, shorter than the double transverse diameter of the club. Discal 
cell of forewing long, at least as long as two thirds of the costal margin; apex of forewing extended. Hind tibiae 
with 4 spurs. 
Review of the S p e c i e s. 
A. Forewing with distinct hyaline spots. 
a. Fringes of forewings at least between the apex and vein 2 uni-coloured dark brown. 
§. Hyaline spots of the forewing whitish and small (cf. margaritata 80 f); discal cell of the forewing 
only in the anterior longitudinal half with a hyaline spot, fringes brown. 
*. Hindwing beneath with an irregular, broad, white, lustrous silvery transverse band edged with 
blackish, between the costal margin and vein 1 b; also at the proximal margin in 1 a with a large, 
long white spot which sometimes unites with the median band. Veins of the hindwing beneath 
not white nor whitish. A. comus. 
**. Hindwing beneath with a broad, white (not lustrous silvery) transverse area which begins at 
the costal margin and reaches or almost reaches to the proximal margin, but which is always,
