the Butterflies of the White Nile. 43 



the Bahr al-Zarafa (glycera). Loat met with it (glycera) 

 commonly near Kaka and at Mongalla, also four males 

 at Gondokoro. The Swedes seem to have found it pretty 

 common at Renk and Kaka {henglini). Selous took both 

 sexes at Tawfikiya (f. heuglini). 



I did not come across it in 1909, but in 1912 found it 

 from Gebel Ahmad Agha (a degree and a half south of 

 the furthest point reached by me in 1909), at most of the 

 places visited right up to Rejaf. It was distinctly com- 

 moner south of Shambi [Lat. 7° 0' N.], being especially 

 abundant at Mongalla [Lat. 5° 12' N.]. It varied in 

 size, and the female varied in the proportion of black and 

 orange in the tip of the fore-wing. 



Col. Yerbury took it at Aden {nouna and saxeus), also 

 on the Somali coast. Under the name nouna it is well 

 known as the Algerian Teracolus. Its larva feeds on a 

 species of Capparis.

The type (male) of this little-known butterfly came from 

 Ambukol. Aurivillius (1. p. 439) gives as other localities 

 " ? Angola, ? Damaraland : Kehaboth (Coll. Stand.)," but 

 the same author writing later (3. p. 59) says : " Mit sicher- 

 heit nur aus Nubien bekannt." 



The Swedish expedition took two males at Khartum. 



In 1909 I took four males and a female at Khartum, and 

 also four males at Soba. 



In 1912 I took three males near Soba station, on the 

 opposite side of the Blue Nile to the ruins of the city. I 

 also took three males and a female at Kaderu, opposite to 

 the battlefield of Kerreri (Omdurman). 



The Hon. N. C. Rothschild took a Teracolus near Shendi, 

 where it was abundant, and believes that he saw the same 

 species on the battlefield of Kerreri in March 1900.* This 

 he named T. liagore, Klug (18. p. 21), but Dr. Jordan, who 

 kindly re-examined the specimens at my suggestion, agrees 

 that they should be referred to ephyia. 



The British Museum has two specimens, males, labelled 

 " Upper Egypt." 



* In my two flying visits to the battlefield, in 1909 and 1912, I 

 did not take any Teracoli, though I have a recollection of having 

 seen one.
