suffusion in hindwing, and by the fact that the discal spot in forewing, 1 b, is 

 slightly nearer margin than the spot above it in 2, whereas in A. equatorialis this 

 spot is further from margin, and by other minor details. 



The male armature is different from that of A. equatorialis. 



cJ. Forewing dull to bright or pinkish ochreous ; costa, apex, and hindmargin 

 very narrowly black ; base with slight or moderate dnsky suffusion ; area just 

 beyoud discal row of spots rather paler, and apical area more richly coloured ; 

 black internervular streaks on apex and hindmargin ; a black spot in cell, one 

 on discocellular ; a row of five beyond cell, and nearly in a straight line at right 

 angles to costa ; a spot near base of area 2 ; beneath it and slightly more distally 

 placed a spot in 1 i, and in same area a subbasal spot 2 mm. before origin of 



nervnle 2. Hindwing : ground-colour same as in primary, sometimes rather 



paler ; spots corresponding with those beneath, but faint near inner margin ; a 

 moderately wide black basal suffusion, and a narrow hindmarginal border formed 

 of a narrow black marginal line and rather flat internervular arches enclosing 

 spots of ground- colour. 



Underside. Forewing as above, but paler, and spots smaller ; two small spots 



at base of costa. Hindwing duller than above, base touched with rose-pink, 



followed by pale ochreous ; marginal border more sharply traced than above, and 

 enclosing pale ochreous spots ; black spots, one in 8 near precostal, two in 7 ; 

 discal spots in 6, 5, 4, 3, 2, \c, I b, and 1 '/ ; two in cell, a basal and a snbbasal 

 in 1 c ; beneath the former a spot in 1 b, and a basal spot in 1 a ; a spot at base 

 of 5 on M.D.O. 



Head and thorax black with brown tufts ; base of abdomen black with pale 

 lateral spots ; remainder white or yellowish. 



Expanse, 50 — 60 mm.

8. Acraea periphanes Oberthiir. 



An examination of a fine series of this species in the Hope Department at 

 Oxford shows that this extremely variable Acraea presents five fairly well-defined 

 forms including the type. These variations are neither seasonal nor geographical. 

 They may be classified as follows : 



8 a. A. periphanes f. beni B.-Bak. 



Acraea toii Bethune-Baker, Proc. Zool. Soc. p. 110 (1908). 



This form is characterised by the uniform bright red ground-colour and the 

 absence of the black apical patch in the forewing.

8 b. A. periphanes f. melaina nov. 



Differs from typical examples in having a heavy black basal suffusion in both 

 wings. The hindwing margin is broad with only a trace of pale spots. In the S it 

 radiates into the discal area, and in the ? has a more regular though suffused inner 

 edge, and is widest (about 4-5 mm.) at 1 c and 2.
