of the marginal band on the underside of the hindwing black instead of reddish. Abyssinia. - ab. intermediana Strand is another nearly allied aberration to rougeti, distinguished by the strong development of the red basal streak and the somewhat broader marginal 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 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 cellules 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. 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 marginal spots of almost equal size, which at their proximal end have at most a reddish dot or spot.
