T. regina has in the cf a very large ornamental spot, proximally bordered with black, which in cellule 
6 is about 12 mm. broad and has in cellule 4 a spot which is more than twice as long as broad; the ?? are 
distinguished by having in the black marginal band of the forewing above two rows of light spots, of which 
at least the proximal ones are violet-red or bluish. — regina Trim. ( 1 5 d, 17 b, c) is the winter form, with

slightly reddish unspotted under surface to the hindwing and narrow proximal black bordering to the ornamental 
spot of the cf; the hindwing has no marginal spots or only very small ones. Damaraland, Transvaal and from 
there distributed to British East Africa and Equatoria. The summer form, anax Sm. (17 c, d), is larger and 
beneath pure white or yellowish; the ornamental spot of the cf proximally with broad black border; the 
hindwing above with large (?) or medium-sized (cf) marginal spots and beneath with distinct discal spots; the 
ground-colour of the ? is normally white, but may also be yellow, ab. louisa Suff. (17 c as “flava”); the distal louim. 
spots in the marginal band of the forewing are usually white with or without violet-red scales or sometimes 
yellow, ab. flavimacula (17 c). flavimacula.

entirely without black bordering and hence directly touches the white ground-colour, which sometimes even 
penetrates between the parts of the spot. In lorti the ornamental spot is large, in cellule 6 at least 12 mm. 
in breadth, and continuous; it begins at the costal margin exactly opposite tbe apex of the cell. In the cf 
the veins of the upper surface are finely black and the hindwing without marginal spot; the ? has a yellowish 
white ornamental spot on the forewing, which is divided by the usual black submarginal spots and is either 
unicolorous (18 a), or sprinkled with small violet-red dots (17 d); the under surface in both sexes more or less 
reddish and in the ? with discal spots. Somaliland.

spot extending at least to the middle of cellule 8. The hindwing of the cf in the summer form above with 
marginal spots and beneath with discal spots, in the winter form with no markings on either surface. 
The ?? have above a very broad black marginal band on both wings; on the forewing it contains only one, often 
incomplete row of light spots; the ground-colour is white (= ab. foliaceus Btlr., 17 e) or sulphur-yellow (= ab. foliaceus.

T. puniceus Btlr. 118 a, b) is very nearly allied to the preceding species and only differs in the male puniceus. 
in having the ornamental spot posteriorly bounded by vein 4 and in the female in the black marginal band 
of the forewing, which here also encloses only one row of spots, being proximally long-toothed on the veins; 
in the summer form the black submarginal spots of the forewing are large and completely united with the 
marginal band, in the winter form, f. flavescens (18b), they are better separated or almost free; in the typical flavescens.

5 and 6; a black spot at the end of the cell; otherwise both wings are entirely without markings, above pure 
white, beneath slightly yellowish; ? unknown. Portuguese South-East Africa. — flotowi Suff. (15d) has a flotowi. 
somewhat broader marginal band on the forewing, reaching the hinder angle, and an ornamental spot composed 
of 4 contiguous spots in cellules 5—8; on both surfaces a black dot at the end of the cell; the wings otherwise 
white without distinct markings; ? unknown. German East Africa. — chromiferus Both. (18b, c) only chromiferus 
differs from the preceding in having the marginal band and the ornamental spot still broader; the hindwing 
has often small marginal dots above; the ? is more or less yellowish white and is distinguished from all the 
other species of this subgroup by the entirely free submarginal spots of the forewing, which are widely 
separated from one another and from the marginal band; in cellule 5 and in cellule 6 there is usually a violet- 
red dot between the marginal band and the submarginal spots; tbe hindwing has large marginal spots and 
small submarginal spots, its under surface is yellow. Portuguese South-East Africa.

species of the subgroup; the ground-colour is delicate greenish white (the greenish colour comes out too 
weakly in the figure) and beneath the apex of the forewing and the hindwing are light yellowish green; the 
ornamental spot of the cf consists only of 3 small spots in cellules 4—-6; the hindwing is without markings 
above, but has beneath a curved row of small submarginal spots; the ? is unknown. British East Africa: Mt.

the East African in “that the red ornamental spot in cellules 5 and 6 is only composed of a slight dusting, 
which covers two white spots in the black apex; this apex is posteriorly continued as a continuous marginal 
band, which gradually becomes narrower”. Hence the ornamental spot is here enclosed in the black marginal 
band. North-West Cameroons, in the meadow-land near Bamenda.
