VI.— APICOTERMEJS GROUP. 



The placing of this group is quite arbitrary and the inclusion 

 of H opolognathoiermes solely a matter of convenience since no 

 representatives of either genus included have yet been studied by 

 the writer. According to Holmgren, Apicotermes belongs to the 

 Microiermes. group, whilst Silvestri's two African genera 

 H opolognathoiermes and Allognathoiermes have not yet been 

 accorded any place in Holmgren's scheme. Silvestri, however, 

 indicates a relationship as existing between these three genera 

 and he is followed in arranging them as a group in the present 

 sequence between Termes and Nasutitermes. 



Genus hopolognathotermes Silv. (1914). 



H opolognathoiermes sp. 



Specimens representing callow soldiers in the fourth instar 

 were found in a tube marked *' contents of queen cell " in the 

 collection of the Albany Museum. There were only a few of 

 these soldiers and they were associated with a queen, workers 

 and soldiers of Termes {Od onto termes) Iransvaalensis obtained 

 at Vryburg. The determination is by Dr. Silvestri.
