the Butterflies of the White Nile. 47 
65. Catopsilia florella, Fabricius. 
Dunn took this on the Bahr al-Zarafa. The Swedes 
took a solitary male to the south of Kaka. 
It was common during my stay at Kharttiim in 1909, 
less so in 1912. Though I did not myself take this 
butterfly on the White Nile above Khartim, it is very 
possible that I may have seen it. 
Rothschild mentions it as common round Khartim, 
and also as seen at Shendi. Cholmley took several north 
of Suakin. Mrs. Waterfield found it common enough at 
Port Sadan, though I did not myself see it there. Col. 
Yerbury took it freely at Aden. Peel found it abundant 
in Somaliland, and it extends even to Sokotra, where 
Bennett noted of it: “ Fhght strong,” a fact that no one 
acquainted with the insect will dispute. 
It ranges over Arabia, the whole of Africa south of the 
Sahara, and occurs in Madagascar and the Mascarenes. 
At Kharttim I repeatedly saw this butterfly settle upon 
Cassia obovata, Callad., a dwarf shrub with yellow flowers 
that grows commonly on the sand in the outskirts of the 
city. Col. Nurse says that its larva feeds upon species 
of Cassia. 
The strong luscious sweet scent of the males, noticed 
by me in South Africa, was confirmed. 
66. Terias senegalensis, Boisduval. 
Butler considered his chalcomiaeta to be an insular race 
of this species.* 
Found by Dunn on the Bahr al-Zarafa. Loat took three 
males and a female at Gondokoro; the males were “ dry,” 
the female “ intermediate.” 
In 1912 I took a single female, of the dry-season form, 
and saw another specimen, at Masran Island [Lat. 12° 45’ 
N.]. Perhaps that may be taken as about the extreme 
northern limit of this butterfly, which is found throughout 
Africa south of the Sahara, in Madagascar, and in Southern 
Arabia. 
Yerbury took the form chalcomiaeta at Aden. 
67. Terias brigitta, Cramer. 
Taken by Dunn on the Bahr al-Zarafa. Loat took one 
of each sex at Gondokoro in January 1902; the male was
