The Termites of South Africa 107 



Genus APICOTERMES Holmg. (1912). 



Apicotermes tragardhi Holmg. (1913). 



This species is the type of the genus. All three castes were 

 described by Holmgren, the specimens coming from Lake M'Kosi, 

 Amatongaland, collected 30th November, 1905. 



VII.-NASUTITERMES GROUP. 



To this group belong those termites with nasute soldiers. Ac- 

 cording to Holmgren's classification (1912) these all fell to the 

 genus Eutermes sens. lat. and this was subdivided by Holmgren 

 into sixteen sub-genera. Banks (1920) has shown, however, 

 that '* Eutermes " must be reserved for those which in Holmgren's 

 classification have been placed in the genus Microcerotermei 

 Silvestri. Banks has set out his reasons for applying " Nasuti- 

 termes " to Eutermes s. str. Holmgren and, at the same time, 

 gives generic rank to the sub-genus Constrictoiermes Holmg. The 

 South African species here discussed represent four of Holmgren's 

 sub-genera and for our present purpose these particular sub-genera 

 are accorded generic rank. Although a number of African 

 nasutes belong to the genus Nasuiitermes Banks, none have so 

 far been met with in South Africa. There would appear to be 

 no essential di^erence between the imagos and nasuti of either 

 Nasuiitermes or Trinerviiermes, other than there is one soldier 

 caste in Nasutitermes and two or three in Trinervitermes. 



Genus TRINERVITERMES. 



There are many records of species of this genus in South 

 Africa that call for careful review. The first is Termes trinervius 

 Ramb. reported by Hagen (1858). This is a negligible 

 reference and the insect reported is probably T. gemellus Sjostedt. 

 The second is Haviland's (1898) identification of the common 

 upland species of Natal as trinervius Ramb. This identification 

 was purely speculative; the species is here described as havilandi 

 sp. n. The third is that of Sjostedt (1900) ; this authority fol-
