XXXVI. — Records and Descriptions of South African Grass- 

 hoj)pers of the Groups Arcypterse and Scyllinse. By B. P. 

 UvARov, F.E.S., Assistant Entomologist^ Imperial Bureau 

 of Entomology. 



The present paper is the first of a series based on the 

 collection of South African Acridians recently sent to 

 the Imperial Bureau of Entomology for identification by 

 the Division of Entomology, Pretoria, and made chieHy by 

 Messrs. Ch. P. Lonnsbury and J. C. Faure. In working out 

 this collection it has been found practicable to include also 

 the South African material of the British Museum Collection, 

 where many unnamed accessions have recently accumulated. 

 The number of new species and genera amongst the Soutii- 

 African grasshoppers has proved to l)e astonishingly large, 

 and further collecting, especially of the smaller forms, must 

 lead to the discovery of still more novelties ; even amongst 

 the large-sized ones new forms are not infre(iucnt, which 

 indicates that our knowledge of the South African Ortho- 

 pterous fauna is still very inadequate. 



The Group Arcyfterm^. 



There is only one African genus of this group — Psendo- 

 arcyptera, Bol.^ with one species in it, P. carva/hoi. Bob,
