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, 

 King, and coeleslis, Swinhoe]. The food-plant of the larva 

 is Cadaba glandidosa. 



It is a common butterfly at Port Sudan 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 feUci." 



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 Sudan 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, K\ug. 



The type came from Ambukol. 



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' J in 1912. I think, however, that Mrs. 

 Waterfield has taken it at Port Sudan.
