P. antsianaka has an expanse of 60 70 mm. and only occurs on Madagascar. Both wings above 
with white ground-colour; the hindwing on both surfaces quite unicolorous without markings; the forewing 
above and below with a black spot at the end of the cell, above with black marginal band or marginal spots 
and at least in cellule 3 with a large submarginal spot, beneath withouth a trace of marginal spots, but as 
above with 1 — 4 submarginal spots and orange-yellow at the base. — antsianaka Ward. Marginal band of 
the forewing above 6 mm. broad at the apex, sometimes almost broken up into large, long spots; forewing 
on both surfaces with 3 — 4 free or above almost free submarginal spots (in 3, 5, 6 and 8); both wings beneath 
with white ground-colour; the orange-yellow basal spot of the forewing extended to the apex of the cell. ab. 
persimilis Sm. & Kirby only differs from the type-form in having the marginal hand on the upperside of the 
forewing more continuous, not broken up into spots, and the basal spot on the under surface only reaching 
to the middle of the cell; the forewing with a submarginal spot only in cellule 3. ab. lasti Sm. & Kirby 
only differs from persimilis in that the submarginal band of the forewing above is very narrow, only 1 mm. 
in breadth at the apex. f. affinis Mob. is evidently a dry-season form and only differs in the reddish grey 
colour of the underside of the hindwing and of the apex of the forewing; the submarginal spots of the fore¬ 
wing above are more or less completely united with the broad marginal band. 
P. ramona Smith nearly agrees in size and markings with the preceding species and likewise occurs 
only on Madagascar. The hindwing on both sides unicolorous without markings, both sides of the forewing 
with a black spot at the end of the cell; the forewing in the cf above with black marginal band, in the ? 
entirely without marginal band or spots, in the cd with large submarginal spot in cellule 3, in the ? with 
large submarginal spots in lb and 3 and smaller ones in 5 and 6: wings in the cd with white ground-colour, 
the forewing in the apical area bright orange-yellow; the yellow colour covers cellules 2—6, 8 and the apex 
of the cell, beneath the basal part of the cell also is similarly coloured; in the ¥ the forewing is cream-colour 
and the hindwing light orange-yellow. 
P. anomala Btlr. (15b) is an interesting species, peculiar to the island of Socotra, evidently most 
nearly allied to P. antsianaka and like other species seems to point to a former connection between Socotra 
and Madagascar. Both wings above white (cd) or grey-white (?); forewing on both sides with a very large 
black spot at the end of the cell and with submarginal spots in 1 b (sometimes absent in the cd), 3 (large 
and quadrate), and in 5, 6, 8, above also with an unspotted black apical band, which terminates at vein 4; 
hindwing above with a submarginal spot in 5 and 6; beneath the apex of the forewing and the hindwing 
are brownish white; the submarginal spots of the hindwing are absent or only indicated; in the ? the black 
markings are larger than in the cd. 
Daplidice Group. 
Of this group the Ethiopian R.egion possesses only three endemic species. The others belong to the Palearctic Region 
and have spread from there to the eastern and north-eastern parts of the region. The endemic species only occur in South 
and East Africa and are completely absent in West and Central Africa. All the species have in common on the forewing 
a large quadrate black spot at the end of the cell and a white-spotted black apical band formed by tbe union of the marginal and 
submarginal spots. The apical band in the cd terminates abruptly at vein 3, but in the ? is accompanied by a marginal spot on 
vein 3 and a submarginal spot in cellule 1 b. The hindwing has above either only marginal spots (cd) or also a submarginal band, 
which is united by the veins with the marginal spots, thus enclosing 3—5 large white spots of the ground-colour. The ground¬ 
colour of both wings above and beneath white. — In vol. I the Palearctic forms of the group are separated as the genus Leucochloe. 
P. daplidice L. (vol. I, pi. 21 f ). The discocellular of the forewing is white and divides the black spot 
in two parts; the hindwing beneath with numerous large, more or less confluent green or greenish spots and with 
light yellow or white veins; the white marginal spots of the hindwing beneath proximally widened and transversely 
truncate, the white spots of the cell and cellule 7 small and irregular. Is reported as occurring in Abyssinia. 
P. glauconome King (vol. 1, pi. 20 f) only differs from the preceding species in having the white marginal 
spots on the underside of the hindwing proximally rounded or pointed and the white spots of the cell and 
cellule 7 large and rounded. Arabia, Soudan, Somaliland and British East Africa; also on the small island 
of Semha near Socotra. — iranica Bien. (vol. I, 20 f) is somewhat larger and has only slight greenish markings 
at the distal margin and in the middle of the hindwing. Found in Arabia at Maskat. 
The following purely Ethiopian species are distinguished from the two preceding by the discocellular of the forewing 
being black and the veins of the hindwing beneath edged with black or black-grey. 
P. helice L. (14f). The hindwing beneath with yellow longitudinal streaks instead of the submarginal 
spots in all the cellules; the black bordering of veins 2—6 distinctly enlarged before the margin; the spot at 
the end of the cell of the forewing is not joined to the submarginal spots; the white marginal spot in cellule 
4 of the forewing is larger than the marginal spots 3 and 5, and in the. cf proximally connected with 
the ground-colour. The larva is above yellow, beneath bluish green, the dorsal line light blue, border¬ 
ed on each side by a green longitudinal band; the lateral line light yellow; the body with small 
black tubercles and a few short hairs; head bluish with black dots. Distributed from Cape Colony to 
Damaraland on one side and Natal and the Transvaal on the other. — johnstoni Crowl. (15 a) only differs 
in the white marginal spot in cellule 4 of the forewing being scarcely or not at all larger than spots 3 and 5;
