the Butterflies of the White Nile. 19 



2. Tirumala petiverana, Doubleday and Hewitson. 



This was taken by Dunn on the Bahr al-Zarafa, but I 

 did not meet with it myself, and I have no other record from 

 the district. 



It is found in Abyssinia and Somahland, and has a wide 

 range in tropical Africa from East to West. 



Sub-family SATYRINAE. 



3. Yphthima asterope, Klug. The types came from 



Syria and Arabia. 



The sole record that I possess of this butterfly — the only 

 White Nile Satyrine known to me — occurring within the 

 area under consideration, is that of a single example being 

 found upon our steamer near Kanisa [Lat. 6° 50' N.] on 

 February 17th, 1912. 



Selous took a male in 1911 on the Southern Bahr al- 

 Ghazal. It is not uncommon at Port Sudan, and Col. 

 Yerbury found it in some numbers at Aden. Dr. Dixey 

 and I took it in Natal and Rhodesia ; it is indeed a common 

 and widely distributed African species. The Hope collec- 

 tion contains specimens from British East Africa, Lake 

 Nyassa, Somahland, and Lagos. 



Sub-family NYMPHALINAE. 



4. Pyrameis cardui, Linn. 



This cosmopoHtan species was taken by Capt. Dunn on 

 the Bahr al-Zarafa, also by Loat — a single female at Kaka. 

 The Swedes took two males at Ad-Duwem. 



Though in 1909 I found cardui common near the point 

 of junction of the Blue and White Niles, and saw 'it at 

 the same place in 1912, it is remarkable that I have no 

 record of having even seen it on either of my voyages up 

 the White Nile. It may reasonably be inferred that it 

 is not very common in that district, at all events during 

 the month of February. 



The Rothschild party took one on the Atbara ; Yerbury 

 found it commonly at Aden ; Peel did not take it in Somali- 

 land, but Bennett found it " common everywhere " in 

 Sokotra. Personally I have found it common enough 

 in Algeria, Cairo, Aswan, Natal and Cape Colony.
