I.— Undescribed Species of African Crane-flies in the Collec- 

 tion of the British Museum {Natural History) : Tipulidre, 

 Diptera. — Part I. Subfamily Linmobiinse. By Charles 

 P. Alexander, Ph.D., Urbaua, Illinois, U.S.A. 



For several years past the writer has been engaged in the 

 preparation of a monographic revision of the Tipuloidean 

 flies of the Ethiopian Region. During the progress of this 

 study the collections of many of the Museums in America, 

 South A.frica, and Europe were kindly sent me for study by 

 the authorities in charge. The largest and most important 

 collections of tropical African crane-flies are those contained 

 in the British Museum of Natural History, and it is with 

 the deepest appreciation and thanks that the writer acknow- 

 ledges the kind assistance of Mr. F. W. Edwards in securing 

 the loan of these unrivalled collections. The species herein 

 diagnosed as new will be keyed, and many of them figured, 

 in the forthcoming revision mentioned above.
