the Butterflies of the White Nile. 21 
At Sallom Junction, on the railway between Port Sadan 
and Khartim, a native boy brought me a male misippus 
in his fingers. Some weeks later I found both sexes fairly 
common at Port Stiidan, where I took typical females as 
well as females of the form imaria, Cram. (mimicking the 
dorippus form of chrysippus). Specimens of both these 
forms had traces of white on the upper surface of the 
hind-wings. 
It is notable that the Cairo collectors know of but two 
specimens having occurred in that district durmg many 
years ; in fact, they look upon it as a great rarity. 
This familiar butterfly ranges over all tropical and South 
Africa as well as India, Ceylon and the Malay Archipelago. 
In two females I detected a slight treacly odour. 
9. Hamanumida daedalus, Fabr. 
This characteristic African butterfly is known to occur 
on the Bahr al-Ghazal, where it has been taken by Selous 
and others, and I am practically certain that I saw a 
specimen on February 15th, 1912, at Mongalla [Lat. 5° 
12’ N.]. 
Col. Yerbury took a single example at Aden; it has been 
reported from Abyssinia and Somaliland. It is found 
throughout tropical Africa, but stops short of Cape Colony. 
10. Neptis agatha, Cram. 
Loat took two specimens at Gondokoro. 
On February 12th, 1912, a short distance below Kiré 
[Lat. 5° 22’ N.| I had a clear unmistakable view from the 
steamer of a Neptis of the size of agatha skimming over 
the herbage at the water’s edge. 
This species has been taken at Shoa, in Abyssinia [circa 
Lat. 10° N.|—perhaps the northern limit of the genus in 
Kast Africa—and has a wide range in Central, Hast, West, 
and South Africa. 
11. Byblia wlithyva, Drury. 
Taken by Dunn on the Bahr al-Zarafa. Loat took a 
female near Kaka [Lat. 10° 40’ N.], where the Swedish 
expedition also took a female. 
In 1912 I took in all five specimens, viz.—a female at 
Melfit [Lat. 10° 27’ N.], a male and two females at Tawfi- 
kiya [Lat. 9° 25’ N.], and a female at Kanisa [ Lat. 6° 50’ N.].
