The Termites of South Africa 1 1 3 



sects from Lake Sibayi referred to auriceps by Holmgren represent 

 a species different from trincrviformis. It may be added that if the 

 nanitic and giant nasuti of trinervifcrmis are taken into account 

 then the antennae are XII.. XIII., XIV. and XV. jointed. 



Trinervitermes havilandi sp. n. 



= Termes trinervius sensu Haviland (1898). 



= Eutermes trinervius sensu Sjostedt, from Natal (1900). 



= Termes trinervius, in part, Fuller (1915). 



Locality: Haviland Rail, Natal, nest series collected by the 

 writer from the same spot as that in which Haviland obtained 

 his material. This species may prove to be widely distributed 

 in the Transvaal and Orange Free State. 



Trinervitermes zuluensis Holmg. (1913). 



= Trinervitermes dispar f. zuluensis Holmg. (1913). 



= Trinervitermes dispar f. dispar oides Holmg. (1913). 



So far as one can gather from the meagreness of essential 

 criteria in Holmgren's description, zuluensis should fall into the 

 trinervoides group. Up to the present I have seen no imagos from 

 Zululand that do not belong to trinerviformis. 



Localities: Umfolosi Drift, Kosi Bay; Mhlanzinga (Zulu- 

 land). 



Trinervitermes fuscus sp. n. 



The miago of this species is quite outstanding on account of its 

 brown pronotum. 



Localities: Warmbaths, Pienaars River Rail, De Wildt (The 

 Bushveld Basin). Five nest series. 



Trinervitermes ki^rumanensis sp. n. 



This species is exceptional because when viewed from above 

 the clypeus appears to be bordered at either side with brown. This 

 is due to the convexity of the clypeus, not to any inherent colour. 



Locality: Kuruman, Bechuanaland, F. Thomsen, November 

 1916 one nest series; (six imagos). Mounds columnar 6 feet
