PREFACE 3 



should be read in connexion with the following brief papers 

 in Vol. VIII of these Reports — Contents (35)/!, 2 ; (36) b., 

 5, e., 2, II, L, 8,/, 5. 



Dr. G. B. Longstaff's interesting study of the butterflies 

 of the White Nile and their relationships with the Palae- 

 arctic and Ethiopian faunas, occupies (6) and (7), while (8) 

 contains a list of 365 species of butterflies taken (1902-12) 

 between the Rift Valley and the British East African coast, 

 by the Rev, K. St. Aubyn Rogers. The extent of the 

 author's generous assistance to the Department may be 

 inferred from this fine list of his captures. The two last 

 papers (9) and (10), by the late Colonel C. T. Bingham, 

 contain the first part of an extensive monograph on the 

 Ethiopian Hymenoptera Aculeata planned by the author, 

 but unhappily cut short by his lamented death.
