PART I 



During the past few years, the writer has been privileged to 

 study the extensive collections of African crane-flies contained in 

 the principal Muséums of America, Europe and South Africa. 

 The resuit of this study has been a very great increase in our 

 knowledge of the Tipuloidean fauna of the Ethiopian Région. In 

 the présent report are included the descriptions of a few new 

 forms belonging to the Muséum of the Belgian Congo and to the 

 writer. Records of certain insumciently known species are also 

 included. I would express my deep gratitude to the numerous 

 entomologists who hâve cooperated in this study, among whom I 

 would especially mention Drs. Joseph and Michel Bequaert, 

 Dr. H. Schouteden of the Congo Muséum, Mons. E. Séguy of 

 the Paris Muséum, Mr. F. W. Edwards of the British Muséum 

 of Natural History, Dr. R. A. Dummer and Mr. H. K. Munro.
