the Butterflies of the White Nile. 33 
secured no less than eighteen males and nine females. 
My Port Stidan specimens may be distinguished from those 
taken near Khartiim by the greater development of the 
black markings, and more especially by the orange veins 
on the undersides of the hind-wings being edged with black. 
I associate this greater strength of coloration [not present 
in Klug’s types] with spring rains reported by Mrs. Water- 
field as having fallen at Port Stidan, but which did not 
occur at Kharttm. 
The above are all the records that I have come across. 
Boisduval [Sp. Gén. der Lepid., vol. i, sp. 581] only quotes 
Klug. . 
ae ttle doubt that this butterfly is attached to 
the Desert Caper, Capparis aphylla, Roth., a leafless bush 
with bluish-green stems and inconspicuous flowers with 
red stamens. 
Three males appeared to have a faint sweet scent, 
suggesting in one case Gorse. 
42. Teracolus calais, Cramer (= dynamene, Klug, = 
carnifer, Butler). 
Klug’s types came from Ambukél, and from “ Arabia 
deserta.” 
Dunn took it on the Bahr al-Zarafa.: 
In 1909 I took two at Tawila, and in 1912 I captured 
in all twelve specimens at various points on the White 
Nile from Tawila in Lat. 13° 16’ N., up to Kanisa in Lat. 
6° 50’ N., half my specimens coming from the latter place. 
Col. Yerbury found it one of the commonest butterflies 
at Aden, where its larva feeds on the Salvadora persica, 
Linn. [Nat. Ord. Salvadoraceae]. 
It has a wide range in Africa—Abyssinia, Somaliland, 
Victoria Nyanza district, British East Africa, German Hast 
Africa, the Congo, Damaraland, Angola; in Asia it is found 
in Arabia, Persia, Sind and North-west India; but in 
Southern India it gives place to 7. amatus, Fabricius. 
43. Teracolus phisadia, Godart ( = arne, Klug). 
Klug recorded this from Ambuk6l as well as from 
“* Arabia deserta.”’ 
Capt. Dunn took it on the Bahr al-Zarafa. Loat took 
five males and two females near Kak&. Selous took two 
males at Tawila. The Swedes took four males and a
