the Butterflies of the White Nile. 25 



Shortly, it may be said that the range of this butterfly 

 in North East Africa extends from Luxor to Gondokoro. 



It is common at Aden, and Bennett took a specimen in 

 Sokotra. Thrupp took it in SomaUland. It also occurs in 

 Senegal. 



According to Bingham (4. vol. ii, p. 419) it occurs in 

 Persia and Baluchistan as well as throughout India and in 

 Ceylon. This and the next species reach Europe. 



22. Tarucus telicanus, Lang (= plinius, Fabr. = pulcher, 

 Murray). 



Loat took a male near Kaka [Lat. 10° 40' N.). In 1912 

 I took a male at Hillet al-Nuwer [Lat. 8° 13' N.] and in the 

 same year took two specimens at Port Sudan. 



In 1909 I took one at Aswan, two at Luxor, and another 

 as far north as Tel al-Amarna [Lat. 27° 37' N.] ; but though 

 ranging in the Nile Valley from that latitude down to 

 8° 13' N., it would not appear to be common at any of the 

 places named. 



Though the species is well known in Central and South 

 Africa as well as at Aden, and is found in Northern India, 

 I have no record from Somaliland or Sokotra. 



23. Castalius usemia, Neave. 



Mr. Neave's types of this neatly marked little butterfly 

 were taken in the Victoria Nyanza district. 



I was fortunate in securing a single example at the Rejaf 

 wooding station [Lat. 4° 50' N.]. 



24. Cupido cretosus, Butler. 



A female was brought home by the Swedish expedition 

 from Renk [Lat. 11°45'N.]; concerning this Aurivillius 

 remarks : " This rare species was hitherto only recorded 

 from Senegal and from Abyssinia." The variety C. lactin- 

 atus, Butler, has been met with in Somaliland. 



25. Catochrysops eleusis, Demaison. 



This httle-known but very distinct " Blue " was taken 

 by the Rothschild party at Aswan, Wadi Haifa, and at 

 Nakhila on the Atbara. I have myself met with it at 

 Aswan, Abu Simbel, and Khartum, but not south of the 

 latter place. The Swedish expedition also found it at 

 Khartum. Its range in latitude would therefore appear
