ACKNOWLEDGEMENTS 



I wish to thank the many people who have helped by lending material, who have 

 allowed me to study type specimens, who have answered questions and who have 

 sent genitalia drawings : Dr. C. W. Benson, Dr. L. A. Berger, Mr. R. H. Carcasson, 

 Mr. I. F. B. Common, Dr. A. Diakonoff, Dr. H. J. Hannemann, Monsieur CI. 

 Herbulot, Dr. H. B. D. Kettlewell, Prof. O. Lindner, Dr. E. C. G. Pinhey and Dr. 

 L. Vari. Mr. Carcasson, with his wide knowledge of the topography and vegetation 

 of continental Africa, has given much valuable help, especially in tracing localities 

 and describing their vegetation. 



TREATMENT 



Previously known species have been re-characterized in the same style as those 

 species described for the first time. The colour names used in the descriptions are 

 taken from Ridgway (1912, Color Standards and Color Nomenclature). 



The wing measurements are those of the smallest and the largest specimens of 

 each sex, the measurement being double that from the apex of the fore wing to the 

 centre of the mesothorax. The genitalia of both sexes, where known, of each 

 species have been described and illustrated. Drawings of the genitalia of a male 

 and a female have been fabricated to illustrate the range of characters referred to in 

 the descriptions (Text-figs. 1-3). The scale placed by each drawing represents 

 one millimetre. The half-tone illustrations have been prepared from photographs 

 supplied by Mr. M. G. Sawyers of the Photographic Section of this Museum. 



Bibliographic references appearing in the text and in the synonymy are given in 

 abbreviated form. A full bibliography appears at the end of the paper. 



In examining the species previously included in Cleora, a number of Old World 

 species have been found to belong to other genera. These are listed separately after 

 the check list of included species to be found at the end of this paper. Wherever 

 it has been possible to place these with precision they have been transferred to 

 appropriate genera and new combinations are indicated, but a number of species 

 will probably need new genera erected to accommodate them.
