OBSERVATIONS ON SOME SOUTH AFRICAN TERMITES. 457 



(c) The soldier of T. transvaalensis is said to differ from 

 badius (1) in being smaller aud (2) in having XVI-jointed 

 antennae. But (1) the size of transvaalensis comes 

 within the badius range; (2) I have nest-series of badius 

 fi'om Natal, the soldiers of which are less (7 to 8 mm.) than 

 the transvaalensis range, but unmistakably badius; in 

 another nest collection of badius from Pretoria this range 

 is, total length 7 to 11 nnn., head with mandibules 3'6 to 4*9 

 mm. ; (3) the autotype material shows both XVII and 

 XVI-jointed antennae (in one instance a soldier having the 

 typical XVII-jointed antenna on the left and a pseudo 

 XVI-jointed on the right) ; further, the XVI-jointed antennge 

 are all obviously due to the non-separation of joints III and 

 IV ; in a field collection made in Pretoria the several soldiers 

 present have perfect XVI-jointed antennae and conform in 

 size to that given for transvaalensis, but some show the 

 pseudo-ai'ticulation and moreover the workers display the 

 several antennal patterns of badius and agree in all other 

 features; further, in a nest collection from the same locality, 

 soldiers possessing XVI, XVII, and pseudo XVI-jointed 

 antennas are present whilst the worker chai'acters conform to 

 those of badius; (4) the transvaalensis autotypes have 

 the same peculiar inverted rose-thorn-like tooth near the 

 base of the right mandible; (5) the imagos of T. badius 

 conform in every particular with the description of the 

 imagos of T. transvaalensis. 



Apart from Haviland's material of badius and Sj6stedt^s 

 autotypes of transvaalensis, the series examined comprises 

 twenty-two collections of soldiers and workers ; of these ten 

 were obtained from separate nests and four are field collec- 

 tions from in and around Pretoria ; five are field collections 

 and one a nest collection from various other points in the 

 Transvaal ; one is a field collection from the Orange Free 

 State, another from Pitermaritzburg, Natal. With few 

 exceptions the collections comprise a long series of soldiers 

 and workei'S; in five, kings and queens are represented. 

 There are also three nest collections and two field collections
