black streaks at the extremities of the veins; the forewing without median dot; the wings beneath snow-white, 
the apical third of the forewing a beautiful sulphur-yellow with five free orange-yellow spots at its proximal 
margin. The specimen figured differs from the type in having black marginal dots on the forewing and a 
somewhat smaller ornamental spot. 
8. Sub-Group. 
The ornamental spot of the d is sand-yellow (light ochre-yellowish) and is complete to the apex and the distal 
margin or is distally only irregularly dusted with (black-) grey without black streaks or dots at the extremities of the veins. 
In the ?? the ornamental spot is dull dark brown with a transverse row of ochre-yellow spots. Ground-colour of both wings 
white. The forewing in the d without, in the ? with median dot. 
T. agoye Wallengr. (15 f) has the veins on the upper surface thinly but distinctly black and the proximal 
bordering of the ornamental spot little thick or indistinct; the under surface is pure white or only slightly 
yellowish, Damaraland to the Transvaal.— In bowkeri Trim. (15 f) the veins on the upper surface are not 
black and the proximal black bordering of the ornamental spot is very thick; the underside of the hindwing 
yellowish or reddish. Damaraland, Namaqualand, Griqualand and Basutoland. — zephyrus Marsh, only differs 
from agoye m that the veins are not black, the costal margin of the forewing is narrowly black and the ground¬ 
colour of the forewing is suffused with sulphur-yellow on the proximal side of the ornamental spot. Somaliland. 
9. Sub-Group. 
The species of this subgroup are distinguished by the bright lemon-yellow, sulphur-yellow, rarely almost white 
ground-colour of both wings; in the latter case, however, the ornamental spot is distinctly bordered with sulphur-yellow 
proximally. The ornamental spot is large, orange-yellow, proximally usually without black bordering and reaching vein 2, 
sometimes even vein 1. In the dd the median dot of the forewing is wanting. The are distinguished by a large black 
spot at the end of the cell on the forewing, and by 1—5 (6) black discal spots on the forewing being free, but conected with one 
another; the ornamental spot is smaller than in the d and distally usually bounded by a broad black marginal band. The 
species are very nearly allied inter se. 
T. evarne. The forewing with the apex obtusely rounded; the ornamental spot is of moderate size 
and does not reach the apex of the cell; the hindwing above white or slightly yellowish. — evarne King (20 b) 
is the summer form with the hindwing beneath white or yellowish white and a distinct distal black border 
to the ornamental spot in the d\ the marginal spots of the hindwing are always present and in the ? very 
large. In the winter form, f. citreus Btlr. (= syrtinus Btlr.) (20 d, e) the hindwing is beneath reddish and the 
distal black border of the ornamental spot is very narrow or entirely absent; the marginal dots of the hind¬ 
wing are wanting. The whole of East Africa to Nyassaland. — philippsi Btlr. (20 b, c) is a somewhat smaller 
race occurring in Somaliland, in the summer form of which the marginal dots of the hindwing in the d are 
entirely absent and in the ? much smaller than in evarne; the winter form, sharpei Auriv. (20 c), is still smaller, 
has the hindwing reddish beneath and the distal border of the ornamental spot broken up into isolated dots. 
T. dissociatus Btlr. (20 d, e) has like the preceding species a moderately large ornamental spot, which 
does not reach the cell; the apex of the forewing, however, projects almost as distinctly as in the following 
species and the expanse is greater than in evarne; both wings have an almost white ground-colour; the 
ornamental spot of the d in the summer form is usually proximally finely, distally thickly bordered with black; 
in the winter form the hindwing is reddish beneath and the black bordering of the ornamental spot is feebly 
developed or entirely absent. From Nyassaland to the Kilimandjaro and Victoria Nyanza. 
T. auxo has the apex of the forewing rather strongly produced and a large ornamental spot reaching 
the cell; both wings with yellow ground-colour. — auxo Luc. (20c) is the larger summer form; the ground¬ 
colour is bright sulphur-yellow; the ornamental spot is at least distally distinctly bordered with black and 
the under surface of the hindwing is yellow. — topha Wallengr. (20 d) is the winter form; it is smaller, has 
the ground-colour lighter, the ornamental spot not bordered with black on either side and the under surface 
of the hindwing reddish, sprinkled with brown. The species occurs in South Africa to Matabeleland. Larva 
unicolorous green with a narrow yellow lateral line on segments 4—12; lives on a Capparideae. Pupa with 
very long point to the head; its colour varies from reddish brown to light green. — incretus Btlr. (20 e) is 
the East African race of auxo and occurs from Nyassaland to Uganda; it is somewhat larger and has an even 
larger ornamental spot, which is without proximal black bordering, ab. vulneratus Stgr. (20 f) is only a casual 
aberration with irregular ornamental spot and orange-red marginal band on the hindwing. ¥-ab. panganiensis 
Thur. differs from normal incretus -? in the white ground-colour of both wings. 
10. Sub-Group. 
The under surface of the hindwing and of the apex of the forewing has a fine and rather dense brown or grey 
transverse striation; the hindwing beneath with a dark longitudinal streak from the base through the cell almost to the 
distal margin. The apex of the forewing is sharp, almost rectangular.
