Review of the Species. 
A. The hyaline spots on the hindwing above are situate in a white or yellow median band, or they are sometimes 
indistinct above. 
a. Abdomen above in the centre with a white belt, which is sometimes interrupted by dark dorsal spots. 
Transverse band of the hindwing above white. A. 'philander. 
p. Abdomen without a white belt. Hyaline spots of the forewing and discal area of the hindwing above 
yellow or yellowish. 
*. The yellow discal area of the hindwing above is smaller and more remote from the margin. 
A. leander. 
**. The yellow discal area of the hindwing above is larger and, particularly in 1 b and 5, nearer to the 
margin or almost reaching to it. A. fenestrella. 
B. Hindwing above blackish-brown without any other markings but the white hyaline spots. A. neander. 
A. philander Hopff. (79 h). Hindwing beneath very similar to that of P. ligora Hew., of a pure white, 
with a small dot in the basal half of area 1 c, and large coherent brown discal spots in 1 c and 2. The marginal 
band consists of two divisions being separated in area 1 c, the first of which is situate in the areas 1 a to 1 c, 
being separated from the margin by a white line and being red-brown in 1 a, whilst the second is 
dusted with brown, approximating the margin and ending pointed at vein 8. At the centre of the anal 
margin of the forewing beneath an indistinctly defined white spot reaches to vein 2. West Africa: Togoland 
to Angola. Portuguese East Africa. — Larva green, powdered with white, with a red, yellow-spotted head. 
The pupa rests in a leaf which has been spun together, and it is greyish-white with a somewhat darker dorsal side. 
A. leander Plotz (— coander Mdb.) (79 g) only differs from philander by the marks stated in 
the review and is probably only a form of this species. 
A. fenestrella B.-Bak. The $ is described by the author as follows: ,,Forewing sooty-black with a 
hyaline spot in the angle of vein 2, a small one near the base of area 3, and 3 hyaline dots in a triangle at 
the costal margin, about a third from the apex of the wing. Hindwing sooty-blackish in the centre with 
a large transparent area which is surrounded by light yellow colouring and parted; a light yellowish stripe 
along the fold; the hair-pencil of the $ is light brownish-grey, at the apex grey.“ To this description Neave 
who collected the species in Rhodesia added yet later on: ,,The $$ are distinguished by a greater extent 
of the ochreous-yellow part of the hindwing above, extending between the veins 2 and 7 and at the anal 
angle almost to the margin; this is particularly beneath very distinct. The hyaline spots of the hindwing 
are absent .“ There is only one $ from Rhodesia before me, having been captured by Neave. Its hindwing be¬ 
neath is almost entirely yellowish-white without any other dark markings but a short stripe in the area 8 
at the base of the costal margin, an indistinct brown dot in the basal part of area 1 c, and two large, enti¬ 
rely separate, black marginal spots, one of which is in 2 to 4, the other in 6 and 7; the white ground¬ 
colour thus reaches to the margin in 1 a to 1 c and in 5. Congo District: Makala-Beni and Rhodesia. 
A. neander Plotz (= producta Trim.) (79 g, h). Hindwing beneath dark, violettish-grey with some 
blackish spots and beside the hyaline spots only with an oblong whitish spot in the basal half of area 1 b. 
Gabun to Cape Colony and Delagoa. 
14. Genus: Platylesclies Roll. 
Strongly built Hesperids with a stout body and broad wings, with short antennae and the terminal 
joint of the palpus projecting from the scaling of the second joint. Vein 5 of the forewing rises much nearer 
at 4 than at 6. Hind tibiae with 4 spurs. Smaller species with an expanse of 25 to 38 mm. 
These marks, as well as the upper surface of both wings, being almost similarly coloured in all 
the species, make it very easy to ascertain the species belonging to this genus. Both wings above blackish or 
blackish-brown. Forewing above with S small white hyaline spots (2 oblong ones near the apex of the discal 
cell and one each in 2 to 4, and 6 to 8; that in 2 is always angular and somewhat larger than the others) and 
a triangular, white or yellowish spot in 1 b near the centre of vein 1 b; the proximal half of the anal margin 
with a narrow stripe with white or yellowish hair. Hindwing above with a transverse row of 4 to 6 whitish 
or yellowish, hairy, not transparent discal spots. Prothorax and underside of palpi white or yellowish. The 
species are very much alike and chiefly only differ by the marking on the hindwing beneath. 
Review of the Species. 
A. Apex of the abdomen above purely white. The discal spots 3 and 4 of the forewing are small, almost 
punctiform, entirely separated from each other and with the spot in 2 arranged in an almost straight line 
directed towards the apex of the wing. The hyaline dot 8 of the foiewing is generally absent above.
