208 Dr. F. A. Dixey on Pinacopteryx. 



Before closing this paper, I should wish to say that I 

 am far from supposing that the statements and conclusions 

 therein contained are necessarily final. It is quite possible 

 that a more minute examination of existing specimens, or 

 an accession of fresh collections from the above and other 

 districts, might render necessary a modification of the 

 present results. I can only claim to have done my best 

 with the material at my command; this comprises the 

 series in the National Collection at the British Museum 

 and the Hope Collection at Oxford, the latter containing 

 the very valuable consignments from Capt. R. S. Wilson 

 (Southern Kordofan), Mr. W. S. Loat and Dr. G. B. Long- 

 staff (White Nile), the Rev. K. St. A. Rogers (British East 

 Africa), Mr. C. A. Wiggins (Uganda), Dr. G. D. H. Carpenter 

 (" German " East Africa), Mr. S. A. Neave (Rhodesia), 

 Dr. Longstaff and Mr. G. A. K. Marshall (Cape Colony. 

 Natal, Gazaland and Mashonaland), with others. The care 

 taken by all these gentlemen to furnish their specimens 

 with exact and ample data as to locality and time 

 of capture calls for grateful recognition on the part of 

 those to whom belongs the task of working out and co- 

 ordinating the material provided by their several collec- 

 tions. It is impossible to overestimate the value, for 

 bionomic purposes, of accurate notes of this description. 



To Dr. Eltringham I am indebted for the preparation 

 of a long series of genitalia, from which most of the outline 

 figures which accompany this paper have been drawn. 

 My special thanks are due to him for this and other help 

 which has always been most cordially given.
