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 (heuglini). Selous took both 
sexes at Tawfikiya (f. heuglinc). 
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 (nowna and saxeus), also 
on the Somali coast. Under the name nowna 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: Rehaboth (Coll. Staud.),”’ but 
the same author writing later (3. p. 59) says : “‘ Mit sicher- 
heit nur aus Nubien bekannt.” 
The Swedish expedition took two males at Khartim. 
In 1909 I took four males and a female at Khartiim, and 
also four males at Sdba. 
In 1912 I took three males near Sdba station, on the 
opposite side of the Blue Nile to the ruins of the city. I 
also took three males and a female at Kaderi, 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 Jeracoli, though I have a recollection of having 
seen one.
