100 DR. W. J. HOLLAND ON THE AFRICAN [Jan. 14, 
Ismene keithloa, Trim. Rhop. Afr. Austr. vol. ii. p. 317 (1866). 
Hesperia keithloa, Trim. 8. Afr. Butt. vol. iii. p. 372, pl. xii. 
fig. 9 (1889). 
Rhopalocampta keithloa, Watson, P. Z. 8. 1893, p. 129. 
Hab. South Africa. 
334. R. Bocaert, Sharpe. 
Rhopalocampta bocagii, E. M. Sharpe, P. Z. 8. 1893, p. 557. 
Hab. Island of St. Thomas, W. Africa. 
This species is allied to R. keithloa, Wallgr., upon the underside, 
but is distinguished by the bright metallic blue of the upperside.

Rhopalocampta ratek, Watson, P. Z. 8. 1893, p. 129. 
Hab. Madagascar. 
Mr. Trimen calls attention in the last volume of his work 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. 
336, RK. Hanno, Ploetz. 
I, hanno, Ploetz, S. E. Z. vol. xl. p. 363 (1879), vol. xlv. p. 63 
(1884); Karsch, Berl. Ent. Zeit. vol. xxxviil. p. 266 (1893). 
Hab. Guinea, Valley of Ogové River. 
The insect identified as 2. hanno by Mons. Mabille, and figured 
in the ‘ Novitates Lepidopterologice,’ is R. necho, Ploetz, as has 
been pointed out by Dr. Karsch. &. hanno is much nearer to, if 
not identical with, 2. seyuncta, Mab. 
337. R. nucHo, Ploetz.

: FIRS necho, Karsch, Berl. Ent. Zeit. vol. xxxviii. p. 266 
(1893). 
Hab. Cameroons, Valley of Ogove. 
Mon. Mabille has given us an excellent figure of this species, 
which he has in error referred to 2. hanno, Ploetz. The difference 
is very marked on the underside of the primaries of the two species, 
which in &. necho are light on the inner margin and beyond the end 
of the cell, and in &. hanno are dark, as in A. seyuncta, which I am 
inclined to regard as identical with R. hanno.
