24 Dr. G. B. Longstaff on 
Family LYCAENIDAE. 
19. Polyommatus baeticus, Linné. 
Taken by Dunn on the Bahr al-Zarafa; by Loat near 
Kaka, and at Gondokoro; by Selous near Tawila, and by 
the Swedish expedition at Khartim, Ad-Duwém, and 
Mohadan Zarafa. 
I found it in abundance at Khartim in 1909, and also 
met with it at Ad-Duwém. In 1912 I found it again at the 
last-named place, and also at Rejaf. 
This, probably the most widely-distributed of all the 
“ Blues,” may be said to occur throughout our district, 
but it would not appear to be plentiful except at Khartim. 
Rothschild speaks of it as “common in Egypt from Cairo 
to Khartim.’ He also took it at Al-Nakhila, on the 
Atbara River. I have myself taken a few specimens near 
Cairo and have seen it in some numbers at Aswan. 
It is common at Aden and it has been recorded from 
Abyssinia and Somaliland, and has a wide range in South 
Africa, as well as in Europe, Asia and Australia. 
20. Lachnocnema bibulus, Fabricius. 
The Swedes took two very dwarfed males on Abba Island 
[Lat. 13° 22’ N.}. 
This species has a wide distribution in South, Central, 
East, and West Africa, but I have no other record for the 
White Nile. 
21. Tarucus theophrastus, Fabricius. 
Loat met with this common and widely-distributed insect 
at Kaka, Mongalla and Gondokoro. The Swedes took it at 
Khartiim, Abba Island, Renk and Kaka. 
In 1909, besides seeing it in abundance at Khartim, I 
took it at Sdba (on the Blue Nile), at Ad-Duwém and at 
Tawila. In 1912 it was again abundant near Khartim as 
well as near Sdba station, and on the battlefield of Kerreri. 
Up the White Nile it occurred at Ad-Duwém (commonly), 
Diléb, Shambi (several), Tombé, Kiré, Mongalla, Gondo- 
koro and Rejaf, as well as on the Bahr al-ZarAfa. 
Mr. Rothschild took it commonly at Al-Nakhila and at 
Shendi, but found it rare at Khartiim. In 1909 I took one 
at Wad Ben Naga station, about twenty miles south of 
Shendi, as well as at Aswan and Luxor.
