either figures of the genitalia of the types or specimens compared to 

 the types, or a reference to published illustrations of the same, and 

 photographs of the wings of certain species. The genera and species 

 are listed in alphabetical order within the families, which are arranged 

 in the order adopted by Ross (1944). The most detailed treatment 

 is given under the combination, which in my estimation is correct. 

 If the species was described originally in a different genus or is a 

 synonym, it is listed in the original combination, together with the 

 combination adopted in the present paper, directly under the generic 

 heading. 



I wish to express my sincere appreciation to Dr. P. J. Darlington 

 and to Dr. H. E. Evans for their wholehearted cooperation during 

 my visits to the Museum of Comparative Zoology.
