6 eye-spots ringed with red-yellow. The under surface marked almost as the upper, but with dark transverse 
lines in the basal part. Cape Colony, Kaffirland, Natal and Transvaal. 
L. dingana Trim. Wings above black-brown; the forewing before the apex in cellules (4), 5 and G dingana. 
with 2 or 3 connected, black, white-pupilled eye-spots, which are bordered on both sides by yellow-red, con¬ 
nected spots; beyond the eye-spots the two rows of spots are joined to a small red-yellow spot in cellule 3 
and are farther accompanied by a free spot of the same colour in cellule 2. Hindwing above with 5 eye-spots 
bordered with red-yellow. The under surface is very indistinctly marked; the light spots on the upperside of the 
forewing are indistinct or absent and the eye-spots of the hindwing have no yellow rings. Natal and Transvaal. 
L. oxylus Trim, is very similar to the following species, but larger, and in addition to the distinguish- oxylus. 
ing marks given in the synopsis differing in the lighter rings of the eye-spots on the hindwing. Cape 
Colony and Kaffirland. 
L. clytus L. (28f). Wings above dark brown; the forewing beyond the middle with a curved light clytus 
yellow transverse band, beginning at the costal margin and often reaching vein 1 ; posteriorly it is more or 
less broken up into spots; cellules 5 and 6 each with a white-pupilled eye-spot, which is proximally separated 
by the ground-colour from the yellow spot in the cellule, but distally immediately bounded by three yellow 
spots in cellules 5—7. Hindwing above with 4 or 5 eye-spots ringed with red-yellow. Under surface of the 
forewing dark brown; the light transverse band narrower than above, proximally bordered with blackish and 
behind vein 4 indistinct or absent. Hindwing beneath black-grey with black spots at the base, two very deeply 
dentate transverse lines across the middle and 7 eye-spots, covered with violet-grey scales and having a yellow, 
a blackish and a grey ring. — The pupa is brown-grey with small blackish dots and streaks and has been 
found lying unattached under a stone. — Occurs only in Cape Colony, but is there very common. 
L. mintha Geyer is very similar to the preceding species, but is distinguished at once by the flat, miniha. 
transversely truncate club of the antenna, the whitish veins on the underside of the hindwing, the red base 
of the forewing beneath and the somewhat smaller size. Cape Colony. 
L. cassus L. is rather unlike the preceding species. Wings dark black-brown; forewing above with cassus. 
dark brown-red reflection from the base to far beyond the middle and before the apex with a large, rounded 
eye-spot ornamented with two white dots; hindwing above with 3—5 eye-spots bordered with dark red; the 
basal half of the forewing beneath is dark red and distally bounded by a dark line; the eye-spot appears 
almost as two connected spots. Hindwing beneath with two undulate black transverse lines, which are in¬ 
distinctly bordered with yellowish scales, and with very indistinct eye-spots, scarcely indicated except by grey- 
yellowish scales. — The larva lives on grasses and is light yellowish brown with a line, double black dorsal 
line and a broad dark latero-dorsal line; body clothed all over with short, small dark bristles; head large, 
dark brown; anal points very short. — Pupa light sand-coloured, irrorated with brown; rests free on the 
ground. Cape Colony and Madagascar. The species is fond of rocky districts and flies near the ground. 
L. cassina Btlr. (28 f) only differs in its smaller size, darker ground-colour and the whitish (instead cassina. 
of yellowish) bordering to the markings on the underside of the hindwing. Cape Colony. 
Ypthima Group. 
The following genera differ from all those already mentioned in the simple claws, the naked eyes and in having 
at most two of the veins on the forewing inflated at the base. The species have thin wings and are on the average small, 
having rarely an expanse of more than 40 mm. The genera can easily be distinguished by the following synopsis. 
Synopsis of the Genera. 
I. Veins 10 and 11 of the forewing free from the anterior margin of the cell. The forewing above 
with two simple eye-spots, in cellules 3 and 5 11. Coenyra. 
II. Vein 10 of the forewing arises far beyond the apex of the cell from the stalk of 7—9, vein 11 
alone arising free from the anterior margin of the cell. 
A. Forewing only with single eye-spots. Antenna not or scarcely thickened at the tip. 
12. Physcaeneura. 
B. Forewing before the apex in cell ules 4 and 5 with a large, bi-pupil l ed eye-spot, rarely with a 
further spot in cellule 2. 
* Only vein 12 of the forewing inflated at the base. 
a. Antenna with distinctly defined, more or less flattened club. 13. Pseudonymplia. 
b. Antenna with little projecting, irregularly rounded club. 14. Neocoenyra. 
** Both vein 12 and the lower median vein of the forewing inflated at the base; the latter, 
however, only slightly. 15. Ypthima.
