C. Opis Dr. (46 e, f). In the A the wings are black above, with blue reflection and bright blue transverse 
lines, 3 or 4 in the cell of the forewing and 3 distally to it, the third shortly before the distal margin, and 5 
on the hindwing; the under surface is chequered with violet-grey and dark brown. The $ is black-brown above 
with grey-yellow instead of blue transverse lines and with a common broad yellow median band running from 
vein 3 on the forewing to the middle of the inner margin of the hindwing; on the under surface not only the 
median band but also almost the whole distal part of the hipdwing (except the apex) and a marginal band on 
the forewing are light yellow with lunulate brown submarginal line; the basal part of both wings is dark grey 
with brown -spots. Sierra Leone to Angola and Uganda. 
14. Genus : Pseii<larg,v!inis Karsch. 
As the name indicates, the single species belonging here strongly recalls in colour and markings the 
middle-sized Palearctic Argynnis species, but it still more resembles Atella phalantha Drury. In the neuration, 
however, as indicated in the generic synopsis, it agrees quite closely with the following genus Catuna. Concern¬ 
ing the early stages nothing is known. 
Ps. hegemone Godt. (= duodecimpunctata Snell.) (46 f). Both wings orange-yellow above with black 
transverse lines and spots in and at the cell, and behind the cell on the forewing with three and on the hind¬ 
wing with two transverse rows of free or almost free black spots and a more or less thick black marginal line; 
the under surface is lighter but with the same dark markings and further with a common rust-brown median 
line, which runs from the apex of the forewing to the inner margin of the hindwing and in the $ is much broad¬ 
er, almost forming a band; before the apex of the forewing are placed on both surfaces 3 or 4 white sub¬ 
marginal dots. Cameroons to Angola and Uganda. - obscurata Griinb. is distinguished by having all the black 
markings more strongly developed and occurs in the Cameroons. — nyassae Bartel (46 f) on the other hand 
is more weakly marked than the type-form, has the black markings smaller and entirely lacks the dark mar¬ 
ginal line on the upperside of both wings. Nyassaland and Rhodesia. 
15. Genus: Catulist Kirby. 
All the species have a similar, very characteristic pattern, the blackish or dark grey ground-colour 
of the upper surface being divided into angled or rounded spots by fine yellow or grey-yellow lines; these lines 
are very irregularly arranged on the forewing, being in particular very distinct in the cell and at the hindmargin 
in cellules 1 a and 2, while occasionally they form light rings to the rounded spots of the ground-colour; on the 
hindwing on the contrary they occur in the distal part as three continuous transverse lines. The hindwing 
is further characterized by a light median transverse band; this is narrow at its commencement at vein lb 
near the base, runs towards the apex and anteriorly becomes gradually broader, so that it almost entirely covers 
cellules 5 and 6 and in 6 nearly reaches the distal margin. The under surface is light yellow with more or less 
developed dark markings. 
Tha larva, like that of Euphaedra, has on either side of the dorsum a row of long, strongly branched 
spines, spread out laterally; they are, however, somewhat shorter than in Euphaedra and without such dense 
feather-like branches. 
The pupa has the ventral surface strongly and uniformly curved, but bears no dorsal spine; the head 
has two short, obtuse points and the cremaster is straight. 
C. sikorana Rogenh. (46 d) differs from the other species in having the median band of the hindwing 
yellow-red and on the forewing a sharply defined white subapical band composed of 3 spots in cellules 4—6. 
At the posterior side of the cell of the forewing there are three dark, light-margined spots in a straight line one 
after another, close at the base of cellules 1 b— 3. German East Africa. 
C. crithea Drury was the first species of the genus described, as long ago as 1773. The median band 
of the hind wing is light yellow and the white subapical band of the forewing is absent, but otherwise the mark¬ 
ings agree very nearly with those of sikorana, (46 d) and the three dark, light-ringed, round spots at the base 
of cellules 1 b— 3 stand out very sharply. Sierra Leone to the Congo and Uganda. — Larva green with glossy 
black head and black spines. Pupa light green with small dots and streaks of black-green or blue colour. 
C. oberthueri Karsch (46 d, e) differs from crithea in the entire absence of the dark spot at the base 
of cellule 3 on the forewing. Avhile the black basal area of cellules 1 a and 1 b is distally bounded by an irregu¬ 
larly curved yellowish line and encloses in 1 b two elongate grey-yellow spots; thus there is only at the base 
of cellule 2 a rounded free spot. The under surface in the $ is almost unicolorous white-yellow, but that of the 
$ is rather well marked. Cameroons to the Congo. 
C. angustata Fldr. is very similar to the preceding species, only differing in having the black spot which 
covers the base of cellules 1 a and 1 b on the upperside of the forewing unicolorous and of uniform breadth and 
distally bounded by an almost straight yellowish line parallel with the cell.
