62. Eronia cleodora, Hiibner. 



The Sudan form is var. erxia, Hewitson, which is more 

 similar to the Natal form than to the race with very 

 wide black borders which is found in the Mombasa 

 district. 



Loat took a wet-season male at Mongalla [Lat. 5° 12' N.]. 

 Selous took a small wet-season male near Tawfikiya 

 [Lat. 9° 25' N.]. The Swedes took a small (51 mm.) male 

 as far north as Gebel fin [Lat. 12° 37' N.]. 



In 1912 I took two males at Renk [Lat. 11° 45' N.], and 

 saw another specimen at Kiro [Lat. 5° 22' N.]. 



This handsome insect ranges over the whole of the 

 Eastern side of Central and Southern Africa, and it also 

 occurs in Angola. 



63. Eronia leda, Boisduval. 



In 1912 I secured a specimen of this very swift butterfly 

 on the tinv island in the Sadd known as Hillet al-Nuwer 

 [Lat. 8° 13' N.], and saw others at Bor [Lat. 6° 13' N.] and 

 at Kiro [Lat. 5° 22' N.]. 



It would appear that this conspicuous South African 

 insect does not get further down the White Nile than the 

 Sadd. 



This species has almost the same but not quite as wide 

 a range over the continent as the preceding. 



64. Leuceronia buquetii, Boisduval. 



Loat took a female at Gondokoro. Selous took a male 

 at Tawila. 



In 1909 I took a female at Tawila, and in 1912 took 

 six specimens in all, viz. two males at Tawila, two males 

 at Masran Island, a female at Kaka wooding station, and 

 a female at Malek [Lat. 6° 7' N.]. 



Its northern hmit, according to these records, is Tawila 

 [Lat. 13° 16' N.], whence came four out of the total of 

 nine specimens. 



Col. Yerbury took it at Aden [form arabica, HopfE.]; 

 Thrupp took the same form in Somahland. 



It is found over nearly all Central and South Africa; 

 it also occurs in Sierra Leone and Madagascar. 



I suspected a faint sweet scent in a male specimen, and 

 noted a sUght " scarcely agreeable " scent in another.
