V. Bcfort on a CoUcction of African Locustidas formed Inj 

 Mr. W. L. Distant, chiefly from the Transvaal. By

[Read February 5th, 1902.] 



The present paper completes my preliminary report on 

 Mr. Distant's collection of African Orthoptera. The 

 Locustidm, by which I understand the grasshoppers and 

 true migratory Locusts, with short antennse, are both 

 numerous and easily collected ; and therefore the number 

 of species and specimens in collections usually exceeds 

 those of other families of Orthoptera. Mr. Distant's col- 

 lection includes a considerable number of new species, 

 here described, which will, it is hoped, be illustrated, in 

 due course, in the forthcoming parts of his Insecta 

 Transvaediensia. 



I have also taken the opportunity of introducing oc- 

 casional synonymic notes and corrections, and notices of 

 some additional species recorded from the Transvaal, but 

 not obtained by Mr. Distant. Thus enlarged, the present 

 paper enumerates 125 species, and a few obscure or im- 

 mature forms remain over for further consideration. 



In all, two new genera and thirty-three new species are 

 characterized in the present paper, of which seven new 

 species are described under each of the two genera Chroto- 

 gonus, Serville, and Xi])]iicera, Lamarck.
