5. Precis cebrene, Trimeii. 



Dunn took this species on the Bahr al-Zarafa, and Loat 

 took two near Kosti [Lat. 13° 10' N.]. 



In 1912 I distinctly saw this butterfly on a thorny bush 

 at Ad-Duwem [Lat. 14° N.], also near Kanisa [Lat/ 6° 50' 



N.]. 



Cholmley took a few at Ambaia Erba; Yerbury found 

 it common at Aden ; Grant in Sokotra, and Peel in Somali- 

 land; it occurs also in Abyssinia. 



It is an abundant African species, being found throughout 

 the whole of South Africa and at Lagos on the West Coast. 



The closely allied P. oenone, Hiibner, takes its place in 

 the Oriental region. 



6. Precis clelia, Cramer. 



Taken by Dunn on the Bahr al-Zarafa and by Loat at 

 Gondokoro. 



In 1912 I took single specimens at Hillet al-Nuwer [Lat. 

 8° 13'], Gondoroko and Rejaf. 



Peel took it in Somaliland; Yerbury took one specimen 

 at Aden, while Bennett reported it as very common in the 

 mountains of Sokotra. 



It is found throughout Central and South Africa as well 

 as on the West Coast. 



7. Precis boopis, Trimen (= madagascariensis, Guenee). 



This was taken by Dunn on the Bahr al-Zarafa. In 

 1912 I took a single example at Mongalla [Lat. 5° 12' N.]. 



Though ranging over Central and South Africa this 

 species is not so widely distributed as the two preceding. 



8. Hypoliinnas misippus, Linne. 



Mr. H. H. King assured me that this interesting and 

 widely-distributed species was not uncommon at Khartum ; 

 it was also in a collection that he had received from the 

 Bahr al-Ghazal. Dunn took it on the Bahr al-Zarafa. 

 It is, however, quite certain that I did not see this very 

 conspicuous insect during either of my visits to Khartum, 

 or the White Nile. 



The Rothschild party did not see it, but Cholmley met 

 with it at Ambaia Erba, and Yerbury found it commonly 

 at Aden, noting that : " The females of this butterfly 

 mimic all the forms of chrysippus."
