with light-spotted marginal band. Comoro Islands. - leucogyne Btlr. has a transverse stripe at the end of lencogyne- 
the cell of the forewing, but only free submarginal spots on the upperside of the hindwing. Arabia, near 
Aden. — boguensis Fldr. has a black transverse stripe at the end of the cell of the forewing, joining the boguensis 
costal margin, and a light-spotted marginal band, 4—5 mm. in breadth, on the upperside of the hindwing. 
British East Africa and Abyssinia. — infida Btlr. (13b) has a black transverse stripe, which is very thick infida. 
especially in the ?, at the end of the cell of the forewing, and broad marginal bands, often almost without 
spots above; ground-colour in the ? usually yellowish. German East Africa to Somaliland and Equatoria. 
P. mesentina Or. (part I. vol. I, pi. 2Id, e). Wings above with white (cf) or whitish (?) ground-colour; mesentina. 
forewing above with a black transverse stripe at the end of the cell, which covers both the lower and median 
discocellular and also reaches the costal margin; very similar to certain forms of severina and only distinguish¬ 
ed from them by having the light marginal spots in cellules 3—8 on both sides (cf) or at least on the under 
surface (?) large and distinct and as broad as or broader than the black marginal band which bounds it 
proximally; the hindwing either only with black marginal spots at the extremities of the veins, or usually 
also with a narrow black submarginal line, which, forming a curve in each cellule, encloses large, rounded 
white marginal spots; all the veins on the underside of the hindwing always brown or blackish. — Larva 
light yellow, above greenish, on each side a broad, brownish lateral line; head reddish; lives on species of 
Capparis. Pupa light brown, on the dorsum spotted with dark brown; the tubercles at the base of the ab¬ 
domen black, the dorsal line and the lateral lines of the abdomen white. Common everywhere on the con¬ 
tinent of Africa and in Arabia; sometimes occurs in great abundance and migrates in swarms from one dis¬ 
trict to another. — auriginea Btlr. has the hindwing ochre-yellow or cream-yellow beneath and is probably auriginea. 
an extreme seasonal form. Ruwenzori. 
The following species are marked almost exactly like the preceding ones, but differ in that the light marginal spots 
of cellules 3—8 on the under surface of the forewing extend quite to the distal margin, are only separated by the black 
veins and are proximally bounded by the black submarginal band. Sometimes the veins are scarcely darker than the 
ground-colour and hence the submarginal spots are confluent. The first subcostal vein of the forewing is sometimes free, 
sometimes more or less united with the costal vein. 
P. zochalia. Forewing with black spot or transverse streak at the end of the cell; marginal band in 
the cd above always with 3—5 white spots, in the ? sometimes unspotted, but the discal spots in this case 
very thick and reaching the distal margin; hindwing beneath with distinct markings. — voeitzkowi Karsch voellzkowi. 
(13 cl). Both wings above with white ground-colour; hindwing beneath with white ground-colour and without 
dark longitudinal lines in the cell; the base of the costal margin, a longitudinal streak at the inner margin 
and in 1 c, as well as small marginal spots at the extremities of the interneural folds orange-yellow; liindwing 
above in the cd only with black marginal spots, in the ? also with submarginal line; forewing with transverse 
bar at the end of the cell. Madagascar. — zochalia Bdv. (12e) has a black transverse bar at the end of the zochalia. 
cell of the forewing, which reaches the costal margin; hinclwing beneath cream-yellow with distinct dark 
markings and two fine longitudinal lines in the cell; hindwing above white (cd) or bright yellow (?) with black 
spots at the extremities of the veins and a fine, more or less distinct and complete submarginal line; forewing 
with white ground-colour on both sides. Is fond of wooded districts and occurs from Cape Colony to British 
East Africa, also met with by A. Schultze in the interior of the Cameroons region near Bamenda. — ab. 
agrippinides Roll, only differs from zochalia in the entire absence of the submarginal line on the uppersid eagrippinides 
of the hindwing. Amongst the type-form. — f. tanganjikae Lanz (= formosa Btlr) (13 b, c) is probably a langanjikae. 
seasonal form of zochalia and is distinguished by having the discal spot of the forewing in the cd very small 
and rounded, not reaching the costal margin, and the hindwing above without submarginal line; the ? scarcely 
differs from that of zochalia. German and British East Africa. —- ?-ab. ochracea Heron is a female form ochracea. 
in which the forewing also is yellow above. Ruwenzori. 
P. crawshayi Btlr. (13c) is nearly allied to zochalia, but has the black marginal band on the forewing crawsliayi. 
above almost without spots, continuous to the hinder angle and proximally widened in cellule 3, the distal 
spot of the forewing rounded and usually not connected with the costal margin and small punctiform sub¬ 
marginal spots on,the upperside of the hindwing; the markings on the under surface are the same as in 
zochalia, but very dull and indistinct; the hindwing and the distal part of the forewins: have a reddish grey 
ground-colour beneath; in the ? the black submarginal spots of the forewing above are almost completely 
separated by white spots from the marginal band, which is of uniform breadth. British Central Africa, Nyassa- 
land and British East Africa. — lata Heave is larger and has the markings of the under surface somewhat lata. 
more distinct. Lualaba district. 
P. grandidieri Mab. ( 1 3 e) has no discal spot on the forewing, thus differing from all the preceding grandidieri. 
forms. Both wings with white ground-colour and at the extremities of the veins with black marginal spots, 
which are separated beneath and on the upperside of the hindwing, but on the forewing above are united 
into a narrow marginal band; inside this marginal band runs between the costal margin and vein 3 a rather
