 Hab. Island of St. Thomas, W. Africa. 



This species is allied to R. heithloa, Wallgr., upon the underside, 

 but is distinguished by the bright metallic blue of the upperside.

Hab. Madagascar. 



Mr. Trimen calls attention in the last volume of his vt'ork on 

 South-African Butterflies to the fact that this species was erro- 

 neously cited in his former treatise as a South-African form. It 

 is apparently confined to Madagascar.

Hab. Guinea, Valley of Ogove Eiver. 



The insect identified as E. hanno by Mons. Mabille, and figured 

 in the ' Novitates Lepidopterologica,' is B. nedio, Ploetz, as has 

 been pointed out by Dr. Karsch. B. hanno is much nearer to, if 

 not identical with, B. s^uncta, Mab.

Hab. Cameroons, Valley of Ogove. 



Men. Mabille has given us an excellent figure of this species, 

 which he has in error referred to B. haniio, Ploetz. The difference 

 is very marked on the underside of the primaries of the two species, 

 which in B. necho are light on the inner margin and beyond the end 

 of the cell, and in B. hanno are dark, as in B. sejuncta, which I am 

 inclined to regard as identical with B. hanno.
