Antexnal Index. — Imago XIX (pseudo-XX) ; major worker

 XVII ; minor soldier XVII. 



The species under reference is placed as var. mossani- 

 Ijiciis as it is without doubt the one to Avhich Hagen 

 originally gave the status of a variety and to whicli his 

 description, nowadays accepted as the standard for T. 

 bellicosus, mainly applies. The material examined com- 

 prises collections made from nests on the banks of (i) the 

 Zambesi, at Tete, the type locality ; (ii) the Busi, about 30 

 miles west of Beira ; (iii) the Limpopo, near Messina in the 

 northern Transvaal ; (iv) the Umkoinati, at Xinavane in the 

 district of Louren^o Marques ; (v) the Umbulusi, near 

 Delagoa Bay. 



In all these collections except one the antennal index was 

 found to agree with the descriptions of both bellicosus and 

 natalensis, some of the imago antennae being pseudo-XX 

 jointed (fig. 7, a). From one nest, out of four examined at 

 Xinavane, the major soldiers in more or less equal propor- 

 tions exhibited organs of XVII, XVIII, and XIX joints. 

 Fortunately the variations were such as to set at rest any 

 doubt as to their homology. On reference to the figures it 

 will be seen that all the deviations arise from fusions of the
