the Butterflies of the White Nile. 23 
In 1912 the engineer of our steamer took a male on 
board near Ladé, February 13th, 1912 [Lat. 5° 5’ N.}]. 
Mr. Eltringham tells me that this species is found through 
practically the whole of Africa south of the Sahara. 
15. Acraea terpsichore, Linné, form rougeti, Guérin. 
I took a single specimen, February 12th, 1912, at 
Mongalla [Lat. 5° 12’ N.]. 
Mr. Eltringham tells me that this species is even more 
widely distributed than the last, extending to the Islands. 
16. Acraea natalica, Boisduval. 
Taken by Capt. Dunn on the Bahr al-Zarafa. 
Widely distributed in South and East Africa: the 
nearest locality to the White Nile given by Mr. Eltringham 
(13. p. 192) is Kibwezi in British Hast Africa. 
17. Acraea encedon, Linné. 
Loat took a male at Gondokoro which was intermediate 
between the typical form and A. daira, Godman and 
Salvin. The Swedish expedition took a male of the form 
daira at Renk [Lat. 11° 45’ N.], and Selous took three 
males at the same place, as well as two males at Tawfikiya 
[Lat. 9° 25’ N.]; Mr. Trimen says these are all small and 
pale, and more or less inclining to the form daira. 
In 1912 I took a male at Tawfikiyaé which approached 
the form infuscata, Staudinger, and another near Diléb 
Hill [Lat. 9° 22’ N.] of the form lycza, Wallengren, with 
much white about it. 
Thus it will be seen that this species, in several forms, 
ranges in the White Nile district over at least 7° of latitude. 
Mr. Eltringham (13. p. 210) gives its distribution as from 
Sierra Leone to the East Coast and from the Cape to Upper 
Egypt, also to the Islands. 
Its larva feeds on Commelina. 
18. Acraea abdera, Hewitson (= cepheus, Linné). 
Taken by Capt. Dunn on the Bahr al-Zarafa. 
Mr. Eltringham (13. p. 112) gives its range as including 
the Bahr al-Ghazal, the Congo basin, Angola, Gold Coast 
and Gaboon.
