PSEUDACRAEA. By Dr. C. Auriyilltus. 
semire. Ps. semire Gr. (46 a). Both wings black-brown above, in the basal part with large black dots and 
in the middle with green spots, which on the hindwing form a continuous median band, but on the fore wing 
are smaller and widely separated, in the cell of the forewing also two small green spots; the interneural folds 
before theblistal margin with broad, black, light-bordered streaks and on the hindwing between these and 
the green median band with a row of brown-red spots. The under surface is lighter than the upper, especially 
at the base, and the green spots whitish. Sierra Leone to Angola. 
2. Hostilia Group. 
Basal part of both wings with black, usually rounded spots and the hindwing on both surfaces with sharply defined 
black marginal band, spotted with red-yellow, and entirely without black streaks on the interneural folds. Hindwing above 
for the most part and forewing at least at the hindmargin with red-yellow or red ground-colour. 
hostilia. Ps. hostilia Drury is a rare Acraea-like spceies, differing quite considerably from all the others in 
the markings of the wings. The hindwing and the basal half of the forewing are red-yellow above with black 
spots, rounded on the forewing, but on the hindwing united into three transverse streaks; the apical half 
of the forewing is black with whitish or light yellow spots; the yellow marginal spots of the hindwing are large 
and proximally only bounded by narrow black lunules. The under surface is lighter and particularly at the 
warburgi. base whitish. Sierra Leone to Ashanti. — warburgi Auriv. (46 c) is the more southern race and differs 
in having the yellow marginal spots on the upperside of the hindwing very small and proximally bounded 
by thick lunules united into a band. Cameroons and Congo. 
Ps. boisduvali is one of the largest and most beautiful species. As in hostilia, the hindwing is yellow- 
red to red-yellow with black, red-spotted marginal band, but that of boisduvali has in the basal part large round¬ 
ed black spots. Fore wing in the distal part more or less semitransparent with thick black longitudinal streaks 
between the veins, at least in cellules 2 and 3; the black spots in the basal half are large and rounded and 
are present both in the cell and in cellules la—-2; it should be specially noted that one of these spots is placed 
on vein 2. The species is considerably larger than Acraea egina (54 d), but mimics it almost exactly and has 
boisduvali. also local races corresponding to those of egina. — boisduvali Dhl. The forewing in the A i> s smoke-brown, 
only red-yellow in the distal half of cellules la—2, in the $ the upper surface is smoke-brown throughout, en¬ 
tirely without red-yellow. Sierra-Leone to the Congo. Corresponds to the type-form of Acraea egina, which 
colvillei. occurs in the same localities. —- ab. colvillei Btlr. The basal part of the forewing as far as vein 3 red-yellow; 
trimeni. the apical part smoke-brown without yellow markings. Natal to German East Africa. — trimeni Btlr. (46 b) 
only differs from colvillei in having on the forewing a broad ochre-yellow or orange subapical band, which 
at vein 3 is more or less joined to the hindmarginal spot. Natal to German East Africa. Corresponds to the 
form areca (54 e) of Acraea egina, found in the same localities; also occasionally occurs in West Africa as an 
aberration. The larva is black-brown with the spines branched like moss, and lives on Chrysophyllum natalense, 
a tree of the family Sapotaceae. The pupa is green with the point of the head brown and somewhat upcurved 
dcficiens. and the dorsal side strongly curved. — ab. deficiens Karsch was described from a specimen of colvillei in which 
on the forewing the black spots in cellule 1 b and on vein 2 are absent. German East Africa. 
3. Eurytus Group. 
The numerous forms of this group may be known at once by the long, distinct black streaks on the interneural 
folds of the hindwing; forewing always with 5 rounded black spots in the cell and 1 or 2 at the base of cellule 1 b. The 
butterflies stand in interesting but very complicated mimetic relations with the Planema species which fly together with them. 
In the dd 1 he forewing is more pointed with the distal margin straight or slightly emarginate, in the 99 the forewing 
very obtusely rounded with the distal margin curved. 
Ps. dolotnena is distinguished from all the others by the large basal dots of the forewing, which are 
dolomena. surrounded by white or whitish rings. — dolomena Hew. (46 c). Forewing in the $ above with very large 
red hindmarginal spot, covering cellules la—2 and the posterior longitudinal half of the cellUand with a yellow 
subapical band, which at least in cellule 3 forms a large spot and usually has also a streak in cellule 2, nearly 
joined to the hindmarginal spot; in the apical part the black interneural folds are only indistinctly edged with 
grey; the hindwing is yellow-red above with black costal margin and broad black marginal band. In the $ 
the forewmg is black-brown at the base as far as the hindmargin and has in the middle of the hindmargin^a 
light yellow spot, which is only about? mm. in breadth but reaches at least to the middle of cellule 2; the 
subapical band is light yellow; the hindwing is light yellow as far as the middle and then very broadly blackish. 
albostriata. Sierra Leone to Angola. — albostriata Lathy has the hindwing marked as in the type-form, but the forewing 
rubrobasalis. differs in the absence of the subapical band, while its apical part bears long white stripes. Uganda. — rubro- 
basalis Auriv.’ agrees with albostriata as regards the forewing, but has in the $ a sharply defined black marginal 
yharsa. band, only 4 mm. in breadth, on the hindwing. Southern Congo: Katanga. — pharsa Fruhst. was described 
from a A hi which the subapical band of the forewing is white and the hindwing has a sharply defined’marginal 
usagarae. band only 1-—2 mm. in breadth. Possibly the <$ of rubrobasalis. German East Africa. — usagarae Stgr.
