ACRAEA. By Dr. C. Aurivillius. 
lobemba, for the most part white. Zambezi: at the Victoria Falls. — lobemba Eltr. (54 c; as welwitschi). Both wings 
above with bright cherry-red ground-colour and at the base broadly black; fore wing above at the costal margin 
black as far as the cell and with broad black marginal band; discal dots 3 to 6 united into a broad black 
transverse band, confluent with the costal border; median spot and discal dot 2 large. The $ with brown- 
yellow ground-colour. North Rhodesia and southern Congo. 
chilo. A. chilo Godm. (55 a; and 54 c, as barberi). The basal dot in 1 c and the discal dots in 2 to 4 of the fore¬ 
wing all four stand in a line running almost parallel with the costal margin. In this chilo and the following 
species differ from all the rest of the subgroup. Such an arrangement of these dots is also very rare among 
the other African Acraeids, only occurring in niobe, liypoleuca, anacreon, mirifica and approximately also in 
wigginsi and neobule. $: forewing above light yellowish red, somewhat rose-coloured, at the base not or little 
darkened; forewing with the marginal band spotted with orange-yellow, 3 to 6 mm. broad, of uniform breadth 
or widened at the apex, a basal dot in 1 b, 2 in the cell, a median spot and large discal dots in 1 b to 6, of which 
the dot in lb is placed much nearer to the distal margin than the one in 2; hindwing above with indistinctly 
spotted marginal band 3 mm. in breadth and distinct discal dots, the one in 4 placed nearer to the distal 
margin than the rest and the one in 2 near the base of the cellule. Forewing beneath almost as above, but with 
whitish subapical band between discal dots 4 to 6 and the marginal band; hindwing beneath whitish yellow 
with some red spots in 1 a to 1 c and at the base of the costal margin and with large whitish marginal spots. 
In the £ the forewing is hyaline with smaller black dots and larger orange-yellow marginal spots; hindwing 
as in the <$, but more thinly scaled and lighter-coloured and also above with large, often black-dotted, yellow 
crystallina. spots in the marginal band. Kilimandjaro; British East Africa; Somaliland and Abyssinia. §-ab. crystallina 
Smith (54 a) is an extreme form of the in which both wings are hyaline, only at the base slightly yellowish, 
and the fore wing lacks all the black dots and also the marginal band. On account of the lack of markings this 
clue to the identification of this form with chilo fails, and the proof must depend on a comparison of several 
intermediate forms. Eltringham regards crystallina as the typical $ of chilo, but as Godman described and fi¬ 
gured, at the same time as the another $ much more nearly agreeing with it, this latter form must be regarded 
as typical. Kilimandjaro and British East Africa. 
oscari. A. oscari Rothsch. (60 d). Wings above dull red with black marginal band of uniform breadth, on the 
fore wing 5 mm. and enclosing large yellowish marginal spots, on the hind wing only 3 mm. and indistinctly 
spotted; fore whig broad and rounded, above but little black at the base; hindwing above deep black at the 
base as far as vein 2 and then whitish to the apex of the cell; the black spots of both wings very large and 
arranged cpxite as in chilo; wings beneath almost as above, but the hindwing broadly whitish in the middle. 
In the $ the ground-colour is brownish white. Abyssinia. 
Sixth Subgroup. 
This subgroup has been formed for those species in which the marginal band of the hindwing is entirely absent, at least 
beneath, being only represented by a very fine black line. The light marginal spots are likewise absent or are at least 
not bordered with black proximally, forming a light band. In some species or seasonal forms of the preceding subgroups 
a similar result sometimes arises from the reduction of the black markings and as these forms might be looked for here 
they are included in the synopsis of the species. 
Synopsis of the Species. 
I. Fore wing with free discal dots. 
A. Discal dots 1 b to 5 of the hindwing are placed in an almost straight transverse line. 
A. rahira and zitja. 
(cf. p. 262, 266, 267.) 
B. Discal dots 1 b to 5 of the hindwing are not placed in a straight line. 
a) The discal dot in 1 b of the forewing stands directly behind the one in 2. Discal dots 3 and 5 
of the hindwing are placed nearer to the distal margin than the one in 4. 
1. Hindwing on both surfaces only with fine black marginal line. Forewing above entirely or for the 
most part blackish. A. asboloplintha. 
2. Hindwing above with black marginal band 2 mm. in breadth. Forewing above with orange-yellow 
ground-colour. A. atergatis. 
(cf. p. 268.) 
b) The discal dot in 1 b of the forewing stands nearer to the distal margin than the one in 2. 
1. Fore wing without submarginal dots. A. atolmis. 
(cf. p. 274.)
