Republic of South Africa : In addition to that already at the B.M.(N.H.), all 

 the material from the N.C.I., Pretoria has been received and examined. This 

 covers every part of the Republic, and there is no point in giving details of localities 

 or collectors, although a list is available at the B.M.(N.H.). The numbers examined 

 have been as follows : Transvaal, 123 nest series ; Orange Free State, 83 nest series ; 

 Cape Province, 406 nest series. A total of exactly 800 nest series of this species 

 were examined, and all material is in the British Museum (Natural History) unless 

 otherwise stated. 



T. trinervoides is the commonest species south of the River Limpopo in sub- 

 tropical and temperate South Africa, and its most northerly records are from 

 Salisbury, Southern Rhodesia. It covers a wide range of climatic and vegetation 

 types, from the dry subdesert steppe of the interior of Cape Province to the moist 

 tropical coastal savannah forest mosaic of Natal and Mozambique (Keay et al., 

 x 959. types 6 . 9> I 5. 20, 25, 28, 29, and 30). 



The mounds of this species have been described as varying from hemispherical up 

 to 6 feet in diameter, to columnar, 6 feet high. Quantities of cut grass are stored 

 in the mounds as in many other species.
