the Butterflies of the White Nile. 37 
Cholmley took two of the form leo north of Suakin, and 
Yerbury took it at Aden [given under the names acaste, 
Klug, and coelestis, Swinhoe]. The food-plant of the larva 
is Cadaba glandulosa. 
It is a common butterfly at Port Sadan and not as local 
as the next species. I found many females extremely 
worn, suggesting prolonged life. 
This variable insect ranges over Abyssinia, Somaliland, 
British East Africa and German East Africa. 
A male had a distinct musky odour. (Compare 16. 
p- 510.) 
50. Teracolus pleione, Klug (=miriam, Felder). 
The type came: “ex Arabia felici.” 
Petherick took it somewhere on the White Nile, and Loat 
took a female near Kaka [Lat. 10° 40’ N.]. 
On February 5th, 1912, I captured two females at Kaka, 
both of the form with an orange flush, approaching the 
male colouring. I know of no other specimens from the 
White Nile. 
At Port Sidan this butterfly is extremely local; in 
certain spots in the Park it is very abundant, I took also 
a few specimens to the north of the harbour. The males 
had little or no orange flush. 
Col. Yerbury took it in abundance at Aden, where he and 
Col. Nurse noted that it attached itself closely to a certain 
shrub, Cadaba glandulosa [Nat. Ord. Capparidaceae], 
on which the larva feeds. I can confirm this, though I 
did not identify the shrub. Late in the afternoon I have 
beaten the butterflies out of these shrubs in such numbers 
that on several occasions I have had five or six in my net 
at once. 
Col. Yerbury tells me that most of his specimens were 
of a darker yellow than mine, also that in the Aden district 
about one out of every four females has the yellow flush. 
This butterfly has also been found in Abyssinia. 
A male had a scent like Freesia. 
51. Teracolus eris, Klug. 
The type came from Ambukdl. 
The only northern record that I have of this widely- 
spread species is the capture of a solitary male at Masran 
Island [Lat. 12° 45’] in 1912. I think, however, that Mrs, 
Waterfield has taken it at Port Sidan.
