34 Dr. G. B. Longstafi on 
female on Abba Island [Lat. 13° 22’ N.] and at Renk 
[Lat. 11° 45’ N.]. 
In 1909 I took six males and six females at Tawila 
[Lat. 13° 16’ N.]. In 1912 I took in all fifteen males and 
sixteen females, the distribution of which was remarkable. 
A solitary female occurred at “the Mahdi’s place” on 
Abba Island [Lat. 13° 22’ N.]. Thirteen specimens were 
brought home from Tawila, some half-a-dozen miles to 
the south of the last-named locality, where it was as 
common as on the occasion of my first visit. Fifteen 
were taken on Masran Island [Lat. 12° 45’ N.] and a 
solitary male at Mashra Zarafa [Lat. 10° 50’ N.]. 
I have not been able to determine the precise latitude 
of Capt. Dunn’s locality, but it must have been some- 
where between 9° 30’ and 7° 0’ N., or considerably south 
of my localities, which all lie between 13° 22’ N. and 
10° 50’ N., the great majority of the specimens occurring 
a little to the north or south of the 13th parallel. 
Cholmley saw but one example, at Wadi Gabait. Nurse 
and Yerbury found it abundant and variable at Aden; 
its larva feeding on Salvadora persica, Linn. It is also 
recorded from the Lebanon, Somaliland, Abyssinia, 
British East Africa and Senegal. 
My impression is that of a very local butterfly, abundant 
where it occurs, somewhat sluggish in habit and easily 
caught. 
44. Teracolus castalis, Staudinger. 
The only record on the White Nile that I know of is 
my capture of two males at Kanisa [Lat. 6° 50’ N.] on 
February 17th, 1912. 
It occurs in British East Africa, both in the Victoria 
Nyanza Country and at Mombasa, also in Somaliland. 
45. Teracolus chrysonome, Klug. 
The type came from Ambukél. T. helvolus, Butler, is 
the dry-season form. 
Rothschild found it common at Gebel Margel, near 
Shendi. I took a female near Mogran (on the Western, 
or White Nile, side of Khartiim) on February 8th, 1909. 
Cholmley found it very common in January and February 
about Halaib on the Red Sea. Peel took it in Somaliland 
(f. helvolus, Butl.).
