Bor, Malék, Tombé, Kiréd, Mongalla (females abundant, 
males scarce), Lad6, Gondokoro and Rejéf—in fact, 
throughout the district. 
Rothschild took several on the Atbara; it is common 
at Port Sadan and at Aden [under the name of lordaca]. 
It also occurs in Somaliland. B. mesentina has by far the 
widest distribution of the genus, extending as it does over 
the greater part of Africa, Madagascar, Persia, Afghanistan, 
India and Ceylon. 
Yerbury notes its attachment to a species of Capparis 
on which the larva feeds. 
I found the males to have a slight scent, variously 
suggesting the adjectives “musky,” “aromatic,” “flowery.”

[Plate II, figs. 1 g, 29, 3 u.s.] 
The type of this little-known butterfly, a female, was 
captured by Petherick somewhere on the White Nile.* 
Another female was taken by Capt. H. W. Dunn on the 
Bahr al-Zarafa in 1900. 
On March 8th, 1902, Mr. Loat took a male at Gondokoro, 
which was described by Dixey (12. p. 141). 
Meanwhile the authorities at the British Museum had 
identified this species with P. doxo, Godart, but Messrs. 
Trimen and Dixey, who have both carefully examined 
Godart’s type at Edinburgh, are satisfied that this identifi- 
cation is wrong. Godart’s insect appears to come nearest 
to P. sumana, Hopfter.+ 
In February 1912 I was fortunate enough to capture 
twelve specimens of this distinct, though not very attractive 
“ White,” viz. a male and three females at Shambi [Lat. 
7° 0’ N.], a male and two females at Malék [Lat. 6° 7’ N.], 
and three males and two females at Gondokoro [Lat. 
4° 54’ N.]. 
Mr. Loat’s specimens and my own were all found between 
Lat. 7° 0’ N. and Lat. 4° 54’ N., but Capt. Dunn’s specimen 
must have come from further North, probably 8° 30’ N., 
or even 9° N., and the precise locality of Petherick’s speci- 
men is also unknown.
