face of legs red. Wings with scattered red scaling in the cell, 

 round the vitreous spot, and towards the costa beyond, on 

 the anterior wings, and towards the hind margin of the pos- 

 terior wings. Anterior wings with an indistinct nearly straight 

 grey line running from within the apex to the hinder angle ; 

 it curves slightly outwards before reaching the costa, and is 

 nearer the apex than the hinder angle, but does not reach it. 

 The vitreous spot is large, conical, terminating basally in a 

 slight inward curve. Towards the hinder angle is a large 

 patch of whitish dusting, crossed by a white bar, and looking 

 as if the wing had been rubbed. Posterior wings with a large 

 ocellus ; pupil subvitreous, oval, surrounded by a tawny iris 

 and by an inner black and outer red ring. Outside this is a 

 curved grey line, more distinct than on the anterior wings, 

 hardly extending to the costa or inner margin. 



Underside brownish grey, darker outside the transverse 

 lines, which here show brown, with some grey scaling on the 

 inner side, but are better defined, nearer the base, and 

 straighter than above. The red scaling is fainter than above. 

 There is a large chalky-white patch on the anterior wings, 

 covering the space from just below the vitreous spot to the 

 hinder angle. Posterior wings with the ocellus reduced to 

 the vitreou.s spot; within it runs a suffused brownish band 

 from the costa to the inner margin. Anterior wings pointed 

 and strongly hooked at the tip. Posterior wings long, 

 and slightly produced at the anal angle. Antenna? reddish, 

 especially beneath.

A very remarkable species, not closely allied to any other. 

 It has a superficial resemblance to B. eblis, Streck., from the 

 Congo, which is a much larger insect ; but it also appears to 

 have some affinities with Gonimbrasia, though it cannot well 

 be referred to that genus.

c^. Brown, anterior wings with two transverse blackish 

 lines, not very well marked — the first nearly straight, about 

 one third of the length of the inner margin from the base, 

 and with some scattered bluish-white scaling on the outside, 

 especially on the costa; the outer runs obliquely from two 

 thirds of the length of the inner margin to the costa a little 

 before the apex ; it is double (most distinctly so towards the 

 inner margin) and filled up with bluish white; within this
