Trinerviiermes umzinduzii sp. n. 



Imago remarkable for its small body. 



Locality: Pietermaritzburg (Dr. E. Warren, one nest series, 

 November 1918). 



TrinerviteTmes pretoriensis sp. n. 



Locality: Meukelneuk Hill, Pretoria, nesting under stones. 

 Several nest series. 



Trinervitermes abassas sp. n. 



Locality: Abassas on Orange River, Namaqualand. Many 

 imagos caught at lights (J. H. C. Kraphol, March 1 92 1 ) . 



Trinervitermes thermarum sp. n. 



Locality: Warmbaths (Bushveld Basin). Many imagos caught 

 at lights. (Carl Rudolph, December 1916). 



Genus SUBULITERMES Holmgren (1912). 



According to Holmgren's classification there is but one nasutu 

 caste in this genus and the nasuti differ from those of Nasutitermes 

 (a) in exhibiting an aciculate nasum, (b) in having the dorsal 

 profile of the head nearly straight, (c) in possessing workers the 

 clypeus of which is always about as long as half its width, not 

 much shorter as in Nasutitermes. The nasuti antenna are cited as 

 XII. jointed. 



Only one African species has been recorded, S. elegantulus 

 Sjostedt (191 1 ) from the Cameroons and this is but doubtfully 

 referred to Suhulitermes by Holmgren (1912). This author 

 also suggests that Eutermes paucinervius Silv. (1908), from the 

 Kalahari, belongs to Suhulitermes. Only the nasuti and workers 

 are known of the first of these two species. The second is 

 Hamitermes paucinervius. 



We have in Bushmanland and Namaqualand a species of 

 which no imagos have yet been obtained but of which the 

 nasuti are so agreeable with the photo-engravurers of 5. inaniformis 

 of the East Indies, that I have no hesitation in referring the 

 local insect to Suhulitermes; but the nasuti exhibit XIV. jointed 

 antennae and the clypeus of the worker is decidedly longer than 

 half its width (7:10).
