74. Parnara fatuellus, Hopffer. 
This species was taken by Capt. Dunn on the Bahr al- 
Zarafa, but I have no other records of it in that part of the 
world; it occurs in the Victoria Nyanza district, Portuguese 
Kast Africa, Rhodesia and Natal. 
75. Rhopalocampta forestan, Cramer. 
This fine Skipper was also taken by Capt. Dunn, but I 
have no other record. 
Like the preceding this insect has a wide range, including 
Uganda, the Congo, British East Africa, Rhodesia, Natal, 
the Gambia and Sierra Leone. 
A perusal of the above list leads to certain conclusions, 
which are made even more obvious by grouping the species 
in families and sub-families.

The Butterfly Fauna of the White Nile is a very poor 
one, comparable indeed, as far as numbers go, with that of 
the British Isles. 
Several groups are very poorly represented, both as 
regards species and individuals, notably the Satyrinae, of 
which but a single specimen was found among several 
hundreds of butterflies sent home. 
That typically African group, the Acraeinae, was repre- 
sented by very few individuals; the same is true of the 
Papilioninae and the Danainae, while the Nymphalinae are 
not much more numerous. 
The Lycaenidae contribute more species, but they are 
for the most part inconspicuous, and none of them 
strikingly common.
