§2 CHAPTER I 



Diptera — Two-winged flies 



Only 'two groups of blood-sucking flies, the mosquitoes {Culicidae, CuUcinae) and 

 the horse flies & clegs {Tabanidae) were considered sufficiently known for the 

 present purpose. Information about the former was provided, for the Old World 

 by Stackelberg (1937), Marshall (1938), Natvig (1948), and Montshadsky (1951), 

 for North America by Dyar (1928), Matheson (1944) and Carpenter & La Casse 

 (1955). The Tabanids were mainly treated according to Olsoufiev (1937) and 

 Philip (1947). Mr. H. Kauri, Lund, made valuable suggestions on the synonymy 

 of this family.
