ACRAEA. By Dr. C. Auriyilltos. 
to 5 mm. in breadth, which in the <$ is sharply defined, but in the $ sometimes shades into the darkened 
ground-colour without sharp delimitation. Wings beneath lighter, not darkened at the base; forewing without 
dark apical spot; hind wing with bright red spots between the basal dots and between the discal dots and the 
marginal band at least in 1 b to 3; the marginal band with large yellow marginal spots and always sharply 
defined proximally. South and East Africa to Angola, southern Congo and British East Africa. •— Larva light 
yellow with white lateral line, white, black-edged dorsal line and a black streak on each side. Pupa yellowish 
umbrata. white with black markings. -— umbrata Suff. differs in having on the fore wing immediately behind discal 
spots 4 to 6 a broad dark grey, somewhat transparent transverse band, extending from the costal margin 
to vein 3 and distally dentate at the veins; between this band and the dark apical spot four submarginal 
spots of the ground-colour are thus separated off in cellules 3 to 6. The marginal band of the hindwing above 
is narrower than in the type-form and irregularly defined proximally. Mozambique to British East Africa. •— 
aTbida. $-ab. albida ab. nov. approximates to the form umbrata , but has the ground-colour of the upper surface white 
and the marginal band on the upperside of the hindwing much widened, reaching the discal dots; wings 
abadima. beneath whitish yellow. Island of Pemba. — abadima Ribbe (= clarei Neave) forms a transition between 
umbrata and pseudegina. Both wings above with bright orange-yellow ground-colour; it differs from umbrata 
in having the marginal band on the upperside of the hindwing a mere line or only indicated by some black 
scales and the marginal spots on the hindwing beneath very large and only separated by the veins; the grey 
subapical band of the fore wing is lighter, more transparent and more indistinctly defined. The $ is darker and 
the ground-colour forms three whitish spots before the apex of the forewing. Angola to the Canreroons, Uganda 
pseudegina. and Abyssinia. — pseudegina Westw. (55 f) is the north-western race and is distinguished from abadima. by ha¬ 
ving the fore wing above entirely or for the most part blackish or black-grey. Senegal to Nigeria. Larva lighter 
than that of the type-form. 
caecilia. A. caecilia F. is similar to the preceding species, but on an average smaller (expanse 56 to 70 mm.) 
and differs in having the discal dots in cellules 4 to 6 of the forewing smaller, rounder and further removed from 
the apex of the cell; the forewing has 2 to 4 submarginal dots (in lb to 4). Ground-colour above light 
reddish yellow to salmon-colour; base of both wings and apex of the fore wing black for the same extent as 
in natalica ; hindwing above always with sharply defined black marginal band about 2 mm. in breadth, not or 
indistinctly spotted; under surface as in natalica, but the red spots on the hindwing indistinct. Senegal to 
artemisa. Nigeria; Nubia; Uganda; Abyssinia; Somaliland; British and German East Africa. — $-ab. artemisa 
Stoll has the ground-colour above white, with the black markings much widened. West Africa ? — $-ab. 
hypatia. hypatia Drury only differs in the darker, redder ground-colour of the upper surface. Sierra Leone. — pudora 
pudora. A ur { v . (55 g) is an eastern race, in which the black colour at the apex of the forewing is only very narrow and 
umbrina. does not- cover the base of cellules 7 and 8. German and British East Africa. — ab. umbrina Auriv. only 
differs from pudora in the forewing above having between veins 2 and 5 or 6 a grey, semitransparent sub¬ 
marginal nebulous band. German East Africa: Kilimandjaro. 
marnois. A. marnois Rog., which I formerly incorrectly regarded as a form of oncaea, is, as Eltringham 
has discovered, very nearly allied to caecilia and probably only a form of it. Wings above sand-yellow; at the 
base narrowly blackish; the black colour does not reach vein 2; at the apex and distal margin narrowly 
darkened, but much more broadly than in caecilia pudora ; basal and discal dots on both wings as in caecilia. 
Soudan. 
oncaea. A. oncaea Hpff. (55 e) is distinguished at once by the fine black submarginal longitudinal streaks in 
cellules 3 to 5 (to 6) of the fore wing; the discal dot in 6 is usually wanting on the fore wing. A '■ the forewing 
is thinly scaled, with dull orange-yellow ground-colour, at the base not darkened, and at the apex only black 
for a breadth of 2 mm.; discal dots usually small and punctiform, arranged exactly as in caecilia. Hind¬ 
wing more densely scaled than the fore wing and above more reddish; its marginal band very narrow but more 
distinctly spotted. In the $ the wings have the ground-colour above dark grey and the fore wing has a broad 
white subapical band from the costal margin to vein 3. South and East Africa to the southern Congo region 
obscura. and Abyssinia. $-ab. obscura Suff. Forewing above brown, hindwing above whitish with rose-reel spots at the 
defasciata. base, at the inner margin and behind the discal dots. defasciata Suff. Forewing brown without white 
alboradiata. subapical band. $-ab. alboradiata Suff. has the veins of the hindwing white. $-ab. modesta Suff. Hindwing 
modesta. w ith a large white area in the middle. —■ caoncius Suff. is a seasonal form (?), in which the apex of the fore- 
liacea. w i n g above has only a fine black marginal line quite as on the under surface. German East Africa, ab. liacea 
Suff. only differs in having the marginal band of the hindwing not sharply defined above and composed of thick 
black lunules beneath. German East Africa. 
alergatis. A. atergatis Westw. (55 f) has two rather different seasonal forms. In both forms the wings above are 
bright uniform orange-yellow to the base, beneath in the dry-season form lighter and in the rainy-season 
form somewhat darker and more reddish than above; the black dots are arranged as in oncaea, but in the rainy- 
season form very large and thick; the forewing above is only narrowly black at the costal and distal margins, 
but without apical spot, and has strong black streaks in 3 to 6; the hindwing is a little blackened at the base 
of cellule 1 c and the cell; the seasonal forms differ particularly in the development of the marginal band
