l c —2 ( 3 ), otherwise broken up into spots. The forewing in the light yellow with a very large black hind- 
marginal spot, anteriorly rounded and limited by vein 3, and completely covering the base of cellules 1 a—2, 
and with a blackish marginal line; cell more or less darkened brown-yellow; submarginal dots usually present. 
In the $ the forewing is black above with three small white spots beyond the apex of the cell in cellules 4 -—6 
and with broad yellow marginal band, which is separated by a thick blackish marginal line from the distal 
margin itself. Gold Coast to Kuilu. 
C. alexander Suff. Of this species only the $ is known. It is similar to that of fumana (34 c), but dlexander. 
differs in having on the upperside of the forewing instead of the three white spots a white transverse band 
3—4 m m. in breadth, extending from the costal margin at least to vein 3, while the marginal band of the hind¬ 
wing is much broader, 8—13 mm., and strongly narrowed towards the anal angle. The distal margin of both 
wings is less dentate than in fumana. From Pungo Andongo in Loanda.

band of the hindwing terminates anteriorly in collide 6 or at most reaches vein 7 and encloses a thick conti¬ 
nuous,. or almost continuous submarginal line. In the S the black hindmarginal spot of the forewing covers 
almost the whole of the cell and in cellules 1 a and 1 b nearly reaches the distal margin. In the $ the fore wing 
is blackish above to the apex, with a transverse row of 5 white conical spots in cellules 2 —6 and a complete 
submarginal row of white, black-dotted crescents. Congo and Ruwenzori. 
C. fumosa Stgr. (35 a not $). In the $ the hindwing is unicolorous black above, without mark- fumosa. 
ings. The fore wing is light yellow with narrow black marginal band, large triangular black submarginal 
spots in 3 and 4 and a large, anteriorly rounded hindmarginal spot, reaching the base of vein 3 but in cellules 
1 b and 2 separated by the yellow ground-colour from the dark marginal band. The $ is unknown. Kuilu

preceding species in the dark hindmarginal spot of the forewing reaching the distal margin in cellules 1 a 
and 1 b, and anteriorly extending little beyond vein 2 and being only weakly curved; the dark marginal 
band is much thickened in cellules 3 and 4, but forms no independent submarginal spots. Median band of the 
under surface very broad and blackish. Congo.

C. superba Auriv. is only known in the female and is perhaps the $ to one of the preceding species, superba. 
It has an expanse of 90 mm. and quite agrees in shape with the other $$ of this group. Both wings are black 
above; the forewing has a white transverse band 7 mm. in breadth, extending from the middle of the costal 
margin nearly to the hinder angle and enclosing one or two dark spots in cellules 1 a and 2 ; the hindwing 
has a dark yellow marginal band 11—12 mm. in breadth, which terminates anteriorly in cellule 6 and is separa¬ 
ted from the distal margin by a thick dark marginal line; the submarginal line is widely removed from the 
distal margin and only represented by free, tear-shaped black spots. The white transverse band of the forewing 
is reproduced beneath; the hinclwing beneath has a white median band about 2 mm. in breadth. South Cameroons. 
7. Caenis Group. 
The numerous species of this group only agree in the characters given in the synopsis and are often very different 
beneath, but at the same time form such a series of gradations that they cannot be further subdivided. The sexes are usually 
quite different above in colour and markings and the identity of the jvj and $$ is still uncertain in many cases. 
C. herminia Smith (35 a). In the both wings above have the ground-colour cream-yellow, at the herminia. 
distal margin broadly ochre-yellow. The base of both wings and the inner margin of the hindwing for a breadth 
of 5 mm. deep/black; immediately beyond the middle runs a black-brown discal band, also 5 mm. in breadth, 
beginning in cellule 6 of the forewing and joining the black inner-marginal band in cellule 1 c of the hindwing; 
hence the light median band is distally dark-margined and on the hindwing posteriorly terminates in a 
sharp triangular point; the distal area is ochre-yellow outside the discal band and tra’versed by the black 
submarginal line, which is formed of sagittate spots; the distal margin itself is narrowly darkened and is almost 
entire. The $ is unknown. Cameroons and Congo region to Lake Albert Nyanza. — althea Drury is only known althea. 
to me from the figure in Drury’s work; it may possibly be the $ of herminia. Both wings black-brown above, 
at the distal margin somewhat lighter brown, somewhat beyond the middle with a straight white transverse 
band only 2 mm. in breadth and whitish submarginal spots, in a sharply angled row; the forewing in addition 
with three white spots in the basal part of cellules 4— 6 . Sierra Leone. 
C. weymeri Suff. (35 c). The as the figure shows, approaches that of herminia, but differs in having weymeri.
