34 Dr. G. B. Longstaff 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 locahty, 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 locaHties, 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 Ambukol. 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 Khartum) on February 8th, 1909. 

 Cholmley found it very common in January and February 

 about Halaib on the Red Sea. Peel took it in Somahland 

 (f. helvolus, Butl.).
