26 Dr. G. B. Longstafi on 
to be from 24°—153° N. It is usually common where it 
occurs, and at Aswan it appeared to be attached to the 
pink-flowered Lotus arabicus, Linn. 
26. Catochrysops malathana, Boisduval, var.  nilotica, 
Aurivillius. 
Two males were taken by the Swedes to the South of 
Kaka [Lat. 10° 40’ N.]. 
I have no other record in the Sfidan of this common 
Central and South African butterfly, which has also been 
reported from Lagos and Madagascar, as well as from 
Lahej in Southern Arabia. 
27. Zizera lysimon, Hiibner. This includes Z. karsandra, 
Moore, and, according to De Nicéville, also Z. knysna, 
Trimen. 
In 1909 I took this fairly commonly at Khartim, also 
a single example at Kosti [Lat. 13° 10’ N.] and another 
at Luxor. 
In 1912 I took two on Abba Island, one at Kédék, also 
one at Tawfikiya [Lat. 9° 25’ N.], as well as one at Port 
Sadan. 
Rothschild took one at Nakhila (f. karsandra); Bennett 
found it plentiful in Sokotra, and Yerbury took it at Aden 
(f. knysna). 
This species is common in Central and South Africa, but 
I have no record of it on the White Nile south of 9° 25’ N. 
According to Bingham (4. vol. u, p. 358) it extends 
northwards to Southern Europe, Central and Western 
Asia; eastwards to India and Ceylon; southwards to 
Malaya and Australia. 
28. Chilades trochilus, Freyer. 
Loat took three at K4ka [Lat. 10° 40’ N.]. 
In 1909 I took one at Asw4n, and another at Kharttim. 
In 1912 I took three at Port Sidén. Cholmley took it 
north of Suakin; Yerbury at Aden; also Peel in Somaliland. 
It occurs also in the Victoria Nyanza district, British 
Kast Africa, Portuguese East Africa, Rhodesia, and also at 
Lagos. To these Bingham (4. vol. i, p. 368) adds South 
Eastern Europe, Central Asia, India, Ceylon, Burma, 
Malaya, and Australia.
