marginal band; hindwing beneath with a few black dots in the basal part and with sharply defined black, 
light-spotted marginal band; subapical band of the forewing completely united with the basal area, en¬ 
closing a quadrate black spot at the end of the cell. Sierra Leone. — rougeti Guer. (= eliana Strand) has, rougeti. 
like the type-form, large light marginal spots on both wings above, but differs in the forewing having beneath 
at the distal margin only sharply prominent black vein-ends and no proximally defined light marginal spots, 
the light ground-colour reaching the distal margin between the veins without interruption; the light sub- 
apical band of the forewing is sometimes separate, sometimes united with the light basal part; basally straight 
and cut off almost vertically to the costal margin. Was described from specimens from Abyssinia, but occurs 
almost identically also in South and East Africa and on Madagascar. Females with almost transparent, whi¬ 
tish ground-colour on both wings may be called $-ab. manjaca Bdv. They occur especially on Madagascar, manjaca.

reaching the marginal band. German East Africa. — ab. toka Strand closely approximates to typical rougeti, toka. 
only differing materially in having the proximal boundary-line of the marginal band on the underside of the 
hindwing black instead of reddish. Abyssinia. — ab. intermediana Strand is another nearly allied aberration interme- 
to rougeti, distinguished by the strong development of the red basal streak and the somewhat broader marginal dmna - 
band on the hindwing beneath. German East Africa. How Strand, who has access to the extensive material 
of the Berlin Museum, could regard intermediana and .eliana (rougeti ) as independent species, is difficult to 
explain, as they obviously intergrade without sharp delimitation into the other terpsichore forms and are only 
characterized by trifling differences. -— ab. contraria Strand is described as follows: “The red spots in the contraria. 
marginal band on the upper surface of both wings are only quite weakly indicated, hence at a cursory glance 
the band appears unicolorous; on the underside of the hindwing some of the black spots in the basal area 
are smaller, namely those of the distal and inner-marginal rows, and in addition the distal round spot in the cell 
is so small as to be almost obsolete. In the distal transverse row only 5 spots are present, namely those in cel¬ 
lules 1 b, 1 c, 2, 4 and 7, of which the one in cellule 4 is punctiform. The bordering of the black marginal 
spots is so broad that the black interspaces are as broad, as the spots themselves. Beyond the black transverse 
spot on the underside of the forewing, which as usual is confluent with the costal margin, there is no further, 
smaller, black spot.” German East Africa. Evidently an extreme aberration of buxtoni. — ab. venturina Thur. venturina. 
forms a transition to the following race; the underside of the hindwing has between the basal and discal 
dots red streaks in 1 c, 7 and in the cell; the marginal band is, however of uniform breadth with mar¬ 
ginal spots of almost equal size, which at their proximal end have at most a reddish dot or spot. Uganda. 
— ventura Hew. (= bukoba Weym.) (55 a) is very similar above to a typical terpsichore or rougeti and has ventura. 
usually a free subapical band on the forewing, with the spots in 4 and 5 much prolonged distally; beneath the 
forewing has at the distal margin sharply prominent black veins and saffron-yellow streaks on the interneural 
folds; this race is characterized by the under surface of the hindwing; this lias thick, sharply defined, bright 
red streaks in the cell and in cellules 1 c and 7 between the basal and the discal dots and occasionally similar 
streaks in other cellules also; the yellow marginal spots are very large and proximally produced into red streaks, 
which are much longer in cellules 1 c to 3 than in cellules 4 and 5; the proximal ends of the red streaks are con¬ 
nected by a dark line which bounds the light median band distally; thus the median band is not of almost uni¬ 
form breadth, as in the previously described forms, but in cellules 4 and 5 strongly convex towards the base. 
In the $ the ground-colour of the upper surface is grey-yellow and the red streaks in the marginal band of 
the hindwing beneath are often absent. Was formerly always regarded as a separate species, but is connected 
with terpsichore by transitional forms and is probably correctly cited by Eltringham as a mere race of terpsichore.

with ventura in markings, but has the ground-colour of both wings light yellowish white, and the subapical 
band of the forewing united with the ground-colour. Victoria Nyanza: Buka Bay. — rangatana Eltr. (60 a) mngatana. 
recalls the $ of ventura-, on the upper surface the dark marginal band of both wings is broader and the mar¬ 
ginal spots are smaller and removed from the distal margin; the subapical band of the forewing is placed 
quite free and consists of three narrow whitish spots in cellules 4 to 6, of which the one in 6 is not half as long 
as the others; the ground-colour of the upper surface light ochre-yelloiv; hindwing beneath whitish yellow and 
marked almost as in ventura-, the red streaks in the basal part, however, united into a transverse band. Bri¬ 
tish East Africa. — According to Trimen the larva is dull green with a white line on each side of the dorsum; 
dorsal and upper lateral spines black, the lower lateral spines yellow; head ochre-yellow; the first two dorsal 
spines projecting forwards and longer than the rest; lives on Hermannia and Triumfetta rhomboidea. Pupa
