As boundary of South Africa I have taken the usual 

 line, i.e., the southern bank of the River Zambesi and the 

 southern boundary of Angola. This line is perhaps more 

 convenient than natural, but our insect-fauna is at present 

 too little known to enable us to define this line in a more 

 satisfactory way if indeed a definite boundary exist at all. 



The majority of species enumerated in this list are from 

 the Cape Colony, Natal, Orange River Colony, and the 

 Transvaal. Comparatively few species are as yet known 

 from Smith West Africa and from Southern Rhodesia, al- 

 though the richness and peculiarity of the latter country 

 leads one to expe-t many future additions. 



Every precaution has been taken to make this work as 

 much up to date as possible and in some cases the kind 

 assistance has been secured from workers in Europe and 

 South Africa. Especially, L. B. I'rout, Esq., and E. Mey 

 rick. M.A.j allowed me to draw freely on their extensn 

 store of knowledge of groups in which they have specialised. 



I shall be grateful to have pointed out to me any errors 

 and omissions, as I hope to make use of any such informa 

 tion when supplements to this list are issued. It is my 

 intention to do this when a sufficient number of species new 

 to .South Africa has been discovered. 



A special label list, printed on one side of the paper 

 only, which can also be used as an exchange list, can lit- 

 obtained at the office of the Transvaal Museum. 



The order in which the genera and species are given is 

 in many instances far from Phylogenetic, but whenever 

 possible such an arrangement has been given. 



My special thanks are due to the Authorities and th< 

 Zntoinologist Mr. C. J. Swierstra, of the Transvaal Museum. 

 for the facilities and assistance given me in compiling and 

 publishing this check-list.
