5._2V(e Crane-flies of South Africa in the South African Museum 
{Diptera, Tipulidae). — By Charles P. Alexander, Cornell Uni- 
versity, Ithaca, N.Y. 
Part I. 
(With Plates X-XIV, and 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. Pcringuey. 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. Pcringuey for his many kindnesses, and also to the various 
collectors of the material, these being credited throughout the text.
