5. The Crane-flies of South Africa /// the South African Museum 

 (Diptera, Tipulidae}. By CHARLES P. ALEXANDER, Cornell Uni- 

 versity, Ithaca, IST.Y. 



PART I. 

 (With Plates X-XIV, aud 2 Text-figures.) 



THE following paper is a consideration of the local crane-flies con- 

 tained in the collection of the South African Museum, Cape Town, and 

 sent to me for determination through the kindness of the Director, 

 Dr. L. Periuguey. The collection is of especial interest in that it 

 contains the majority of the South African species described by 

 Bergroth in 1888, and the re-examination of this material has been 

 very interesting. As has been done in previous papers, the author has 

 supplied figures of the wings and details of the male hypopygia of 

 species that are still insufficiently known. I am greatly indebted to 

 Dr. Peringuey for his many kindnesses, and also to the various 

 collectors of the material, these being credited throughout the text.
