276 Dr. G. B. Longstaff on 



The next two are intermediate between this and the daira 

 form. The sixth is a nearly typical daira, Godm. and 

 Salv., the seventh is of the form lycia, Wall., with some 

 tawny suffusion, and the remainder are lycia of varying 

 degrees of whiteness " (Eltringham). 



All taken at Tira Mandi, Nov. 23, 25, 1904. 



This series shows how much the species may vary in the 

 same place and at the same time. 



17a. Acraea neobule, Doubl. 



One 9, " unusually small " (Eltringham). 

 Taken at Kadugli, Dec. 29, 1904. 



Not in the White Nile list. It occurs in Somaliland, 

 Abyssinia and Socotra, and has a wide African distribution. 



176. Acraea caecilia caecilia, Fabr. 



Two <£# and two $$, Kadugli, Dec. 17, 21, 23, 29, 1904. 



All the specimens " have the characteristics of the 

 western rather than the eastern form. Abyssinian ex- 

 amples may be of the western form or intermediate to 

 pudera, Auriv., the eastern sub-species in which the apical 

 black is narrow and sharply defined " (Eltringham). 



A widely distributed species recorded from Nubia 

 (Ambukol), Abyssinia and Somaliland among other places, 

 but not in the White Nile list. 



[17c. Acraea marnois, Rogen.] 



This is regarded by Aurivillius as a variety of oncaea, 

 HopfL, but Dr. Eltringham (" African species of Acraea," 

 pp. 184, 185) considers it more nearly allied to caldarena 

 and caecilia. As the type (at Vienna) came from the 

 Bahr el-Zarafa it should be added to the White Nile list.] 



17d. Acraea doubledayi sykesi, Sharpe. 



A <?, Kadugli [Lat. 11° 0' N.], Dec. 17, 1904. 



Not in the White Nile list. Dr. Eltringham says of it : 

 " A single $ example of this rare species in exceptionally 

 fine condition. This is the most northern record for the 

 sub-species." The sub-species A. doubledayi arabica, 

 Eltring., occurs in the Azvaki Ravine, S. Arabia.
