basal spot on both surfaces. — varia Trim, is the form occurring in South and East Africa. The cfcf are distinguished 
by the somewhat narrower black marginal band of the forewing, which is continuous at most to vein 3 and is often 
broken up into spots at veins 3 and 4; in the ¥¥ this marginal band is spotted with white or even broken 
up into marginal and submarginal spots. ?-ab. aurora Buff. (15c) has both wings above white; the forewing 
on both surfaces with orange-yellow basal spot; the submarginal spots of the forewing above almost free or 
absent; Natal, Mozambique. ?-ab. mhondana Buff. (21 d); both wings above white; the forewing only beneath 
with orange-red basal spot. German West Africa. In ¥-ab. giara Buff, the forewing is above white without 
basal spot, beneath with orange-red basal spot, the hindwing above light ochre-yellow; East Africa. 
E. usambara Auviv. is very similar to the cf of the preceding species, but has an expanse of only 
45 mm. The wings are white above, the hindwing without markings, but the forewing with a black marginal 
band, which is continuous to vein 3 and is proximally less dentate at the veins than in argia- cf; forewing 
beneath white and as above with a blackish marginal band, which is only yellowish at the margin itself; the 
hindwing is beneath cream-yellow with a rounded brownish submarginal spot in cellule 5. From Usambara 
in German East Africa. The ¥ is unknown to me. 
E. buqueti differs from all the other species in that the underside of the hindwing and that of the 
apex of the forewing are watered with small, fine brown striae, and that the hindwing has beneath a small 
brown ring-spot and a white streak at the end of the cell. Hence the under surface strongly recalls that of 
the Catopsiliae. The ground-colour of both wings is white, on the underside of the hindwing tinged with 
greenish. The species occurs in .South Africa to Angola, in the whole of East Africa, on the Senegal, in 
South Africa and on Madagascar, but is wanting in the West African forest region. — In buqueti Bdv. (21 e) 
the forewing has above a broad black marginal band, which reaches the hinder angle and is continued at 
the costal margin to the base; this band is broader in the ¥ than in the cd; the hindwing is usually without 
markings, but has sometimes especially in the ¥ 4—5 dark marginal spots; the brown streaks of the under 
surface are indistinct, ab. mossambicensis Hpff. only differs from the type-form in the distinctly striated 
under surface, f. arabica Hpff. is a dry-season form, in which the apical band of the forewing above is narrower, 
only reaches vein 3 and is not continued along the costal margin; the under surface is strongly striated, 
f. capensis Hpff. is the extreme dry-season form and only differs from arabica in having the apical band of 
the forewing entirely or almost entirely absent. 
4. Subfamily: Coliadiuae. 
This subfamily is easy to recognize by the characters given on p. 30. The forewing always with only 
11 veins. In proportion to the numerous forms of other parts of the world it is but poorly represented in Africa. 
Synopsis of the Genera. 
A. The hindwing with distinct, basally curved precostal vein. Veins 9 and 10 of the forewing free 
from the anterior margin of the cell, 7 in the distal margin. 11. Catopsilia. 
B. The hindwing without precostal vein. 
a) Veins 9 and 10 of the forewing free from the anterior margin of the cell; vein 7 in the 
apex or in the costal margin. 12. Terias. 
b) Vein 9 of the forewing arises behind the apex of the cell from the stalk of 6, 7 and 8. 
13. Colias. 
11. Genus: Catopsilia Hbn. 
Large species with broad wings. The forewing has an almost straight distal margin and rather sharp 
apex. The distal margin of the hindwing is uniformly rounded. The cfcf of the Ethiopian species all have 
a mealy spot in cellule 7 on the hindwing above and a long hair-pencil on the hindwing beneath close to 
the hindmargin The ¥¥ are usually different from the cfcf in colour and markings. — The larvae are 
gregarious and live on species of Cassia, are somewhat spindle-shaped and have the surface finely granulated. 
Pupa with sharp point to the head and vent.ricose wing-cases. 
C. florella F. (vol. I, pi. 23 g). The cf is above white, with mealy scales at the base of the wings; 
a black dot at the end of the cell of the forewing and sometimes also of the hindwing, otherwise the wings 
are without markings above or only with some small dark spots at the apex and at the distal margin of the 
forewing; the under surface of the hindwing and of the apex and costal margin of the forewing is greenish 
and sprinkled with small, thin dark striae. The ¥ (= rufosparsa Auriv., 21 a) has a greenish yellow ground¬ 
colour to both wings; the forewing has red-brown spots at the apex and distal margin and a larger, brown 
median spot, also the hindwing has usually red-brown marginal spots; beneath both wings are sprinkled with 
red-brown. ¥-ab. hyblaea Bdv. has lighter, white-yellow wings above. In ¥-ab. aleurona Btlr. the wings are 
above almost white at the base and in the middle, only at the distal margin broadly yellowish. In ¥-ab. pyrene
