11. Genus: Perrotia Oberth. 
This genus being unknown to me, probably belongs near to Artitropa or coincides with it. Nothing 
is said about the structure of the veins. In the formation of the antennae and in the marking it closely agrees 
with Artitropx. The most important difference, however, appears to jne to be the shape of the hindwing, 
which is entirely rounded off at the anal angle. The forewing shows 5 or 6 small hyaline spots (2 contiguous 
ones in the discal cell and one each in 2, 3, 6 (and 7), besides a yellow spot or longitudinal streak in 1 b, 
which is white beneath. Only are known. 
P. albiplaga Oberth. Hyaline spots of the forewing above yellowish, beneath white. Hindwing above 
orange, at the anal margin as far as the discal cell and vein 6 broad black and with a black marginal band 
which ends pointedly at the anal angle. Hindwing beneath of a pure white, at the anal margin as far as the 
discal cell and vein 7, at the proximal margin as far as vein 1 b and at the distal margin jet-black; the 
black marginal band is about 2 1 / 2 mm broad in area 1 c, but it gradually tapers off towards the costal angle 
where it is only linear. Fringes of the anal region above yellow, beneath white. Expanse of wings: 40 mm. 
Madagascar: Fenerive. — albimacula Oberth. only differs above by the black marginal band of the hindwing 
not tapering off towards the anal angle and ending pointedly at the centre of the proximal margin, and by 
the black marginal band in 1 c being only 2 mm broad, but in 2 to 5 6 mm broad, and being then entirely 
absent at the apex. The white area thus reaches there to the margin, but it is deeply excised in the centre. 
North Madagascar: Antakares. 
12. Genus: IParoiiyiiins gen. nov. 
The species of this genus were formerly reckoned among Pardaleodes (Holland 1896) or Andronymus 
(Mabille 1903). But they are at once discernible from both these genera by vein 5 of the hindwing being 
entirely absent or only marked by a fold. Vein 2 of the forewing rises a little before the centre of the cell, vein 
4 much nearer at 5 than at 3. The tip of the antennal club is generally straightly porrect, not twice as 
long as the club is thick. Forewing with two small, generally separated hyaline spots in the discal cell and 
one each in 2, 3, 6 to 8, besides with a small spot in 1 b at vein 1. Hindwing above with a large light discal 
spot or a light median band, beneath for the greatest part with a light ground-colour and with a black 
spot near the centre of area I c. 
Review of the Species. 
A. Apical half of abdomen above white or rarely only at the apex darkened. The discal band of the hindwing 
above in the areas 2 and 3 hyaline, semi-transparent. 
a. Transverse band of the hindwing above coherent and yellowish. Forewing beneath in the areas 4 and 5 
near the margin with a whitish diffuse spot. P. ligora. 
(j. Transverse band of the hindwing above in area 1 c almost interrupted, of a pure white. Forewing beneath 
without a light submarginal spot in 4 and 5. P. nevea. 
B. Abdomen above grey or dark brown. Discal area of the hindwing above not showing through in the centre, 
coloured yellow. 
a. Hindwing beneath without a coherent dark marginal band, instead of it only with some dark spots. 
P. xanthias. 
P. alenica. 
P. kelembaensis. 
fh Hindwing beneath with a coherent dark, anteriorly tapering marginal band and a yellow, almost 
spotless ground-colour. P. xanthioides. 
P. ligora Phew. (= thersander Mob.) (79 h). The yellowish-white median band of the hindwing above 
extends from 1 a to 6 and is almost equally broad ($) or anteriorly tapering (d'). Beneath the hindwing is 
white, at the costal margin in area 8 and close in front of the margin between the proximal margin and vein 
6 with a broad black band being widened towards the proximal margin and being red-brown in 1 a and 2 to 
4. In addition a generally separate, jet-black spot in 1 c. Sierra Leone to Angola. 
P. nevea H. Druce (79 d) is very similar to the preceding and only differs by the marks mentioned 
in the review. Congo District: Kassai. 
P. xanthias Mab. (79 d). Hindwing above with a large, yellow' discal area being on all sides bordered 
with black. Fringes and a narrow marginal line in 1 a and 1 b yellow. Beneath the hindwing is light yellow',
