T. transverstigma (sic!) Ham. Bruce (63 a). Forewing above with large orange-red hindmarginal spot, 
which reaches vein 4 and covers almost the whole cell; the black apical part with broad white subapical 
band composed of three spots in cellules 4—6; marginal band on the upperside of the hinclwing unspotted. 
Hindwing beneath with three long, narrow, very obliquely placed black transverse streaks at the costal margin 
and a black longitudinal streak in the cell. Cameroons. 
T. erica Suff. (61 e). Forewing above orange-red, at the costal margin, the apex and the distal margin 
black, in cellules 4—6 and 9 a white subapical band, which in cellule 6 is'much broader than in the other 
cellules, and at the distal margin some white spots. Hindwing above orange-red with black marginal band, 
which encloses a white submargina-l spot in each cellule from 1 c to 5. Hindwing beneath at the costal margin 
with short black streaks, which are separated by white spots. Cameroons. 
T. nyanza Heave approaches the preceding species and, like the latter, is distinguished by the great 
extent of the orange-red colour on the upper surface; on the forewing this reaches the white subapical band, 
which is formed as in erica , and also covers a part of the costal margin distally to the cell; white marginal 
spots are wanting on the forewing, but are well developed on the hindwing. Transverse streaks at the costal 
margin of the hindwing beneath very short and weakly developed. Uganda. 
T. sanguinea Plotz (61 d). Forewing above black with large orange-red hindmarginal spot, which 
reaches vein 4 and completely fills up the cell, and with a subapical band, broadly separated from the hindmar¬ 
ginal spot, consisting of three white spots of almost uniform size in cellules 4—6. The black marginal band on 
the upperside of the hindwing broad, with white spots just before the distal margin. On the under surface 
of the hindwing there are three black transverse streaks at the costal margin, of which the first is short but the 
other two long, reaching vein 5. Cameroons to Angola. 
The following species differ from the preceding in the quite different under surface, which is dark and not 
spotted with white. 
T. actinotina Lathy (62 a). Forewing on both surfaces in the basal part orange-yellow as far as the costal 
margin and vein 4, in the apical part above black with two elongate yellow subapical spots in 5 and 6, beneath 
black-grey with indistinct light subapical spots in 3—6 and broad black bordering to the yellow basal part. 
Hindwing brown-grey beneath with some small black basal dots. Nigeria. 
T. carnuta is a small species, measuring only about 30 mm., and has the under surface yellowish, 
irrorated with black and with some black discal spots; hindwing above red-yellow with black marginal band; 
forewing above black with or without red-yellow hindmarginal spot, which in the $ reaches at least vein 3. 
- carnuta Hew. (61 e). Marginal band on the upperside of the hindwing broad, anteriorly widened and almost 
reaching the apex of the cell; hindmarginal spot of the forewing in the <$ small or absent. Gaboon to Uganda. 
- parva Kirby. Hindmarginal spot on the upperside of the forewing in the $ larger; marginal band of 
the hindwing narrower, not nearly reaching the cell. Sierra Leone to Cameroons. 
T. rogersi Ham. Druce is very similar to T. carnuta and only differs in having the hindmarginal spot 
of the forewing prolonged anteriorly as a transverse band as far as vein 5 or 6. British East Africa. Is pro¬ 
bably only the East African form of carnuta. 
3. Genus: Cooksoilfa Ham. Druce. 
Antenna moderately long with flattened club. Forewing with the costal margin nearly straight, the apex 
almost rectangular and the distal margin curved. Distal margin of the hindwing uniformly rounded. 
The only known species has an Mcraea-like pattern. 
C. trimeni Ham. Druce (63 a). Wings orange-red above; the forewing at the costal margin narrowly 
and at the apex broadly black, with 4 or 5 elongate white spots before the apex; the broad black apical spot 
has its proximal boundary almost straight and is continued in cellules 2—1 a as a narrow marginal band as 
far as the hinder angle; a black dot in the cell and a larger one at its apex; hindwing above with black 
median dot and narrow black, light-spotted marginal band. Forewing beneath almost as above, but instead 
of the white apical spots with quadrate yellow marginal spots in 3—7. Hindwing beneath somewhat more red¬ 
dish with several large black basal and discal dots and two thick undulate or angled black arcuate lines 
before the distal margin. Rhodesia. 
4. Genus : Diirliania Trim. 
The species of this genus are confined to South Africa. They are small butterflies, characterized by the 
large basal lobes of the hindwing and the long pointed terminal joint of the palpus. The cell reaches at most
