neath almost exactly coloured and marked like in S. thecla. Forewing with 2 hyaline dots in 1 b and one 
hyaline spot each in 2, 3, 6 to 8 and 11; that in 2 is large and square. Mozambique and Northern Congo 
District. 
S. subalbicans B.-Bak. is unknown to me, but evidently closely allied to S. maculata. ,,Forewing light sukalbhans. 
brownish; a small hyaline dot in the cell opposite vein 3 and one before it outside of the cell 14 (in area 11?); 
,,a similar subapical dot; a hyaline dot in 3, a large square one in 2, and two hyaline dots in 1 b; a dark sub¬ 
marginal band is angled behind the submarginal dot. Hindwing somewhat darker with traces of a dark median 
band and a postmedian row of dark spots. Hindwing beneath white with a brown costal margin; a small brown 
patch before the cell, and a large brown spot from which a curved line of spots extends to the vein 1 b; a small 
spot at the cell-end; two large united brown spots at the apex of the wing and traces of a row of dark sub¬ 
marginal spots.“ British East Africa. Kisumu. 
The following three species were placed as doubtful to the genus Trichosemeia, although the d lacks 
both the mealy spot of the hindwing and the hair-pencil of the forewing. I have no dd at hand, but it 
seems to me to be impossible to distinguish them from the genus Sarangesa. 
S. brigidella Plotz ( = aurimargo Holl.) (76 f, g, as aurwiargo). Forewing on both sides uni-coloured brigidella. 
blackish-brown without any other markings but three hyaline dots in 6 to 8, forming a triangle. Hindwing 
also blackish-brown, with an orange marginal band in the extent shown by the figures. Sierra Leone; Gabun; 
Niam-Niam. 
S. brigida Plotz (76 h, i; according to Plotz). Forewing above dark brown with 5 hyaline dots, one brigida. 
each in 3, 6 to 8 and the cell, beneath with some large lighter spots. The marking of the hindwing may be 
seen from the figures. Cameroon. 
S. hereus Drc. (76 i). The d is unknown. In the $ the forewing shows 10 hyaline dots, one each in 2 hereus. 
to 9, 11 and in the cell. In a $ I have at hand the hyaline dots of the areas 2 to 5, 11 and of the discal 
cell are absent. Hindwing beneath marked almost the same as in brigida (76 h), but with a brimstone-like 
ground-colour. It may be a female form of brigida? Angola. Ituri. 
10. Genus: Trichosemeia Holl. 
This genus seems only to differ from Sarangesa in the secondary sexual marks of the d> and must 
therefore, in my opinion, not be retained as a separate genus (only as a subgenus of Sarangesa) . A very remark¬ 
able fact, however, is that all the species have four subapical hyaline dots of the forewing (in 6 to 9). The 
dot in 9 is otherwise of very rare occurrence (cf. however S. hereus). Forewing in the d above uni-coloured 
blackish, only with the 4 hyaline dots of the areas 6 to 9. 
Review of the Species. 
A. Hindwing beneath with a bright yellow or orange ground-colour. 
a. Hindwing above uni-colonred black without markings. T. tetrastigma. 
(3. Hindwing above with a very broad yellow or orange marginal band. T. quaterna. 
B. Hindwing beneath with a greyish-yellow or pale olive-brown ground-colour with black fringes; area 1 b 
almost entirely darkened. T. subolivescens. 
T. tetrastigma Mob. d- Forewing on both sides monotonously blackish with minute hyaline dots in tetrastigma. 
4 to 9. Hindwing above black without markings, beneath bright yellow with black fringes, at the base and 
costal margin scarcely darkened, but with black rounded discal dots in 1 c, 4 to 7, and a similar basal dot 
in 7. $ unknown to me. Cameroon. 
T. quaterna Mab. (76 h). d-■ Forewing on both sides black, only with four hyaline dots in 6 to 9. quaterna. 
Hindwing above in the basal half black; in the marginal half yellow and orange with two jet-black marginal 
spots in 6 and 7; beneath the yellow colour is still more expanded, leaving free a large black spot in 7 and 
a small one in 6. Abdomen above with yellow rings. The $ (76 h) has longer and lighter forewings with hya¬ 
line dots in 1 b to 9, ] 1 and the cell. Sierra Leone. 
T. subolivescens Holl. (76 h). Holland’s figure of the d copied here makes any further description subolivcs- 
superflnous. The as far as I know, is not known. Matabele Land. ccr,s - 
To this genus may also belong tristiflea (76 b). It was figured from a specimen in the Berlin Museum trisiifica. 
without any statement as to the genus. The species is jrrobably not yet described and entirely unknown to 
me, nor is its habitat known.
