ACRAEA. By Dr. C. Auriyillius. 
wing above with light median band which reaches the inner margin or at least vein 1 b. 
f. Hindwing beneath uniform light orange-yellow, not lighter in the middle, above 
only with dark marginal line. A. grosvenori. 
ff. Hindwing beneath distinctly lighter in the middle, above with black marginal band. 
1. Marginal band much narrower than the light median band. 
a. Hindwing beneath without dark marginal band. A. pcirrhasia <$; pelopeia. 
b. Hindwing beneath with dark marginal band and longitudinal streaks proxi- 
mally united by a line. A. peneleos <$. 
2. Marginal band as broad as the median band or broader. A. servona f. rubra ; 
(A. safie); A. newtoni. 
00. Forewing entirely transparent, only narrowly darkened at the margins and altogether 
without light spots. Hindwing above and beneath black, occasionally with red median 
area, which, however, does not reach the inner margin A. cinerea. 
b. The apical part of the forewing fully scaled, unspotted or with r e d spots in 4—6. 
* The veins and the short longitudinal streaks on the underside of the hindwing united into a 
black marginal band 3 mm. in breadth; this marginal band encloses two small spots of the 
yellow ground-colour in each cellule. A. buschbecki. 
** The black longitudinal streaks at the distal margin of the hind wing beneath longer and quite 
free. A. orina 
B. The longitudinal streaks of the interneural folds on the under surface of the hindwing are proxi- 
mally thickened, distally gradually narrowed, and scarcely if at all reach the distal margin, 
f. Hindwing without diaphanous spots. 
a. Cell of the forewing at the apex with a sharply defined light yellow, white or transparent spot. 
* The spot in the cell and in cellule 2 of the forewing completely scaled, sulphur-yellow. 
A. melanoxantlm. 
** These spots white and semitransparent. A. mairessei. 
b. Cell of the forewing unicolorous without spots or partially diaphanous; the hyaline or transpa¬ 
rent parts, however, not sharply defined. A. penelope. 
tf. Hindwing with diaphanous spots in cellules 3—6. A. semivitrea. 
II. Hindwing above at the base not or scarcely darkened and hence with free or almost free basal dots; 
the black discal dots are well developed and are normally placed in a curve beyond the cell. 
A. Hindwing with transparent or semitransparent, grey to blackish marginal band, in which the streaks 
of the interneural folds are only very indistinct. 
a) Marginal band of the hindwing 3.5 mm. in breadth at vein 4. A. quirinalis. 
b) Marginal band of the hindwing only about 2 mm. in breadth. A. orestia. 
B. Hindwing with fully scaled, black or black-spotted distal margin. 
a) Forewing at least beyond the middle hyaline or transparent with dark veins and dark margins 
or with transparent spots not sharply defined. 
* The black streaks on the underside of the hindwing are short and do not reach the distal 
margin or only with a very fine point. The fore wing above scaled with red in the cell (at least 
at the base) and in the greater part of cellules 1 b and 2. 
f. Cellule 3 of the forewing vitreus at the base. A. igola 
tf. Cellule 3 of the forewing black-scaled with or without red spot. 
1. The veins at the distal margin of the hindwing beneath broadly black with short, thick 
streaks between them. A. conradti. 
2. The veins and the streaks on the folds not thickened. A. aubyni. 
* * The black streaks on the underside of the hindwing reach the distal margin. 
f. Hindwing above proximally to the black marginal band entirely without black streaks on the 
interneural folds. Basal part of the fore wing scaled with red or red-yellow as far as vein 3. 
1. Hindwing above with large, triangular, contiguous black spots at the extremities of the 
veins. Cell of the forewing brown-red to or almost to its apex. A. sambavae. 
2. Hindwing above with broad, continuous black marginal band. 
a) The outer black dot in the cell of the hindwing placed opposite to vein 2. Cell of the 
forewing scaled with red-brown to or almost to the apex. A. strattipocles. 
b) The outer black dot in the cell of the hindwing placed proximally to vein 2. Cell of the 
forewing more or less broadly diaphanous at the apex. A. masamha. 
f f. Hindwing above proximally to the black marginal band with dark streaks on the interneural 
folds. 
1. Fore wing in the cell to its apex, in cellules 1 a and 1 b almost to the distal margin
