A Monograph of the Formicidae of South Africa. 3 



In the following pages I have copied the original descriptions of 

 those species of which I have not been able to see specimens, such 

 copies being indicated by inverted commas. For the generic 

 descriptions and keys to genera, I have borrowed to a large extent 

 from Prof. Emery's work on the Ponerinae in the " Genera 

 Insectorum," an invaluable work which is indispensable to all 

 students of the family. 



Species represented in the Ehodesia Museum's collection are

 placed after the descriptions of the species. 



It is hardly necessary to give an introductory outline of the 

 external anatomy of the Formicidae, since that information is easily 

 obtained in various entomological textbooks.* 



But it will be necessary, for the understanding of the following 

 descriptions, to give a short explanation of certain features in the 

 anatomy of these insects, and of some modifications in the termin- 

 ology which I have thought desirable to adopt. 



As is well known, the posterior portion of the "thorax" of the
