(J. Expanse 54-62 mm. F.-w. transparent, elongated. Costa 

 and nervures narrowly black, apex narrowly black, continuing 

 as a narrow hind-marginal border expanded into triangular 

 marks at nervule ends. A little black at base most extensive 

 in area la. The transparency of the wing is caused by a total 

 absence of scales, there being no sign even of scale sockets in the 

 glass-like membrane. 



H.-w. brown black at base nearly to end of cell, obscuring 

 some rather large black spots. A black hind- marginal border 

 narrow at apex, about 2 mm. wide as far as nervule 3, after- 

 wards widening out to about 5 mm. at 2. An inner-marginal 

 pale ochreous patch extending partially into area 2. 



Underside f.-w. black portions replaced by pale ochreous 

 striated by black nervule ends and rays, the black powdering 

 of which gradually obliterates the yellow towards the hind 

 angle. Some black at base of area lb. 



In h.-w. the area which is occupied above by the basal black 

 and the inner marginal patch, is here entirely lemon ochreous, 

 the hind-marginal border being of a darker shade of the same 

 colour traversed by black nervule ends and rays. Black 

 spots somewliat variable as follows : — One at base in area 9, 

 one (sometimes two) in area 7, one on discocellular at origin 

 of 6 and 7, three in cell, the first on subbasal sometimes 

 absent, and the others often confluent. A spot at base of 2, a 

 basal and two more distally placed spots in Ic (the latter often 

 confluent), two spots in lb (sometimes confluent) and two 

 in la. 



Head black with a pale yellow spot between eyes and two 

 on collar. Thorax black with a few paler marks. Abdomen 

 black above with lemon ochreous lateral spots arid faint 

 segmental lines. Claws equal. 



$ . Expanse 60-72 mm. Resembles (^ but dark areas rather 

 browner, and the h.-w. inner marginal patch creamy white. 

 In one example before me this patch is reduced to a mere 

 dusting of whitish scales. On the underside the yellow is 

 correspondingly paler and duller. 



This species is quite unlike any other Acraea, and is 

 easily recognised. The type in the Brussels Museum was 

 taken at Lualuaburg in the Southern Congo. A long
