38 Dr. G. B. Longstaff on 
Dr. Dixey and I took a few specimens in South Africa, 
at Ladysmith and the Victoria Falls, but it is a very rapid 
flyer, so that a small proportion only of those seen is actually 
secured. 
Its area of distribution includes Abyssinia, Somaliland, 
the Victoria Nyanza, German East Africa, Rhodesia, 
Matabeleland, Natal and Angola. 
52. Teracolus hetaera, Gerstaecker. 
Mr. Loat took a female of this species near Kaka [Lat. 10° 
40’ N.], which was at first thought by Dr. Dixey (13. p. 146) 
to be a yellow form of the female of 7’. phleqgyas. I have no 
other record for the White Nile. 
Its range extends from the Victoria Nyanza to Mombasa. 
53. Teracolus phlegyas, Butler. 
The synonymy of this species is puzzling. Butler called 
its dry-season form jalone, and the male of the same 
coliagenes. Again T. imperator, Butler, is indistinguishable 
from phlegyas. According to Trimen phlegyas is wone, 
Godart, in spite of the fact that Godart’s description of 
tone agrees closely with the Natal insect. Trimen lays stress 
on the fact that Natal was not known to white men in 
Godart’s day. [He died in 1823.] Dixey, however, con- 
siders the Natal insect to be specrosus, Wallengren [= erone, 
Angas], of which the dry-season form is jobina, Butler, the 
wet-season form zone, Godart. 
The female is very variable and extremely different from 
the male. The types were taken by Petherick on the 
White Nile. Capt. Dunn met with it on the Bahr al-Zarafa. 
Loat took a typical male near Kaka [Lat. 10° 40’ N.]. 
Selous took two females and a male at Tawfikiya [Lat. 
9° 25’ N.]. The Swedes took a male on Abba Island [ Lat. 
13° 22’ N.], also a female near Kaka. 
In 1912 I took in all ten specimens, viz. two males at 
Kir6é [Lat. 5° 22’ N.], two males at Mongalla [Lat. 5° 12’ 
N.], two males and a female at Gondokoro, and three 
males at Rejéf wooding station. 
Thus 7. phlegyas, while it ranges over 84° of latitude 
along the White Nile, would appear to be commonest 
high up the river, above the Sadd. 
Outside our limits this lovely butterfly is met with in 
Abyssinia, British East Africa, German East Africa, 
Rhodesia, Matabeleland, Natal, Damaraland and Senegal.
