wing has a sharply defined, very broad (12—13 mm.) median band, which proximally reaches the commence¬ 
ment of veins 2 and 5 and in the <$ is light yellow above, white beneath, in the $ white on both surfaces; the 
dark marginal band is about 6mm. in breadth and sharply defined; the dark streaks of the folds stand out but 
little in the band. The species is somewhat smaller than those which follow and is characterized especially 
by the broadly rounded fore wing and the small basal area of the hindwing, which is black-brown above, red- 
brown to reddish beneath. German East Africa: Daressalaam to Usambara.— pancalis Jord. has the transverse pancalis.

as the hindmargin. Tanganyika. 
P. formosa Btlr. (59 b) is a little known species very similar to the following; it differs from it in ha- formosa.

at vein 4, while the white median band of the hindwing is narrower; transverse band of the forewing orange-

surface is nearly black; the transverse band of the forewing is light orange-yellow, 10—15mm. in breadth, on 
the distal side more or less convex, towards the base out off obliquely so that its proximal boundary-line is 
placed almost vertically to the costal margin; its spot in cellule 2 is obliquely cut off and almost reaches 
the base of vein 3; in the base of cellule 3 a small rounded black spot; the transverse band reaches to the hind- 
margin and in cellules 1 a— 2 usually also to the distal margin; the median band of the hindwing is white, 
sharply defined and 8—10 mm. in breadth; the sharply prominent black marginal band is consequently 6—10 mm.

P. macarista E. Sharpe (59 b, d). The $ is similar to that of poggei, but the transverse band of the macarista. 
forewing is of almost uniform breadth, narrower and placed more vertically to the inner margin; in addition it 
does not reach the distal margin, hence the black ground-colour of the apex is continued to the hinder angle; 
the white median band of the hindwing is broader than in poggei S and the dark marginal band correspond- 
ingly narrower. In the $ the transverse band of the forewing is white and terminates at vein 2; its spots 
in cellules 2 and 3 are cut off obliquely and almost straight towards the base. Cameroons to the Congo

which begins somewhat beyond the middle of the costal margin, is about 7 mm. in breadth throughout and at 
the hinder angle reaches the hindmargin; in cellules 4—6 it is proximally rounded and touches the extreme 
posterior point of the cell, then in cellules 3 and 2 oblique basewards and almost straight and hence reaches 
vein 2 beyond its middle, so that more than the basal half of cellule 2 is black and cellule 3 has a large 
triangular black spot at the base; the orange-yellow spot in cellule 2 reaches the distal margin and is about 
8 mm. in length, in la and lb the band projects more towards the base than in 2; the hindwing has on both 
surfaces a white median band, at the costal margin about 4 mm. in breadth, at the inner margin 6 mm., its 
proximal edge sharp and rectilinear, the distal less sharp; basal area black above, bright red-brown beneath. $ un¬ 
known to me. The species is nearly allied to poggei , formosa and macarista, but if the shape of the transverse 
band in these species is constant, as is generally accepted, the S described above must be an independent spe¬ 
cies, which may be known at once by the position and shape of the transverse band of the forewing in cellules 
2 and 3. Fongo Tunga. 
P. entalis Jord. was described from a single S and is said to be smaller than poggei and pseudeuryta. entalis. 
Distal margin of the forewing more emarginate; the transverse band almost as in pseudeuryta, projecting more 
distad at vein 4 and on the distal side with three sharp incisions between veins 1 and 4 as in pseudeuryta ; 
the transverse band as broad at the hindmargin as at the costal and on its proximal side curved, about as in 
poggei. The median band on the upperside of the hindwing dirty white, tinged with brownish, not yellowish, 
distally shading quite gradually into the black marginal band; basal area on the underside of the hindwing 
as in poggei and the median band here white. Angola. 
P. pseudeuryta Godm. <t- Salv. (dewitzi Stgr.) (58 c). This species has been the subject of a regrettable pseudeu- 
muddle. In describing their species Goo max and Salvin expressly say that the example was designated by r d ia - 
Dr. Staudinger pseudeuryta spec, nov.. But in “Iris” (vol. 9, p. 210) Stattdixger Avrites that he obtained 
Acraea excisa Btlr. in rather large numbers from the Cameroons and Gaboon and formerly sent it out as 
Acr. pseudeuryta in litt. Consequently in my work “Rhopalocera Aethiopica” I regarded P. excisa and pseud-
