(miles). It is found in Abyssinia, Somaliland (the commonest 

 butterfly at Zaila), the Victorian Nyanza district, British 

 East Africa, German East Africa and in Senegal. 



In two males I detected a slight scent, in one described 

 as " sweet," in the other as " stuffy." 



55, Teracolus achine, Cramer. 



This fine species is variable and accordingly has received 

 several names. T. simplex, Sharpe, was described from a 

 dry-season male from Durban; antevippe, Boisduval, and 

 helle, Butler, are names given by the latter author to 

 Petherick's specimens (both sexes) from the White Nile. 

 Selous, in 1911, took two males of the extreme dry-season 

 form at Tawfikiya [Lat. 9° 25' N.]. 



In 1912 I secured four males and two females on the 

 White Nile, viz. single specimens at Duleb (not far from 

 Tawfikiya), Hillet al-Nuwer, Kanisa and Kiro, and a 

 pair at Rejaf. From these occurrences it may be gathered 

 that on the White Nile T. achine is confined to localities 

 south of Lat. 9° 30' N., and that it is not very common 

 anywhere. 



Cholmley took a dry-season male (simplex, Sharpe) 

 north of Suakin. Peel took a wet-season female in Somali- 

 land. I took six males and four females at Port Sudan. 



It occurs in Rhodesia, Natal, and Cape Colony, and 

 indeed probably over the whole of Africa south of the 

 Sahara, if with Dr. Dixey we reckon the West African 

 T. carteri, Butler, as a sub-species. 



56. Teracolus evippe, Linn6. 



The form of this variable species usually met with on 

 the White Nile is epigone, Felder, which is the same as 

 microcale, Butler. 



Petherick took a male somewhere on the White Nile. 

 Loat took a male and six females at Mongalla. 



I did not meet with this species in 1909, but in 1912 

 took twelve males and two females in localities ranging 

 from Abba Island [Lat. 13° 22' N.] to Gondokoro. It was 

 not common anywhere, but three out of my fourteen 

 specimens were captured on the small patch of firm ground 

 in the Sadd known as Hillet al-Nuwer [Lat. 8° 13' N.]. 



Col. Yerbury met with it at Aden [epigone], but so far 

 as I know it does not occur at Port Sudan.
