There is one soldier caste and a major and minor worker caste. 

 All these stand in such close relationship to the three corres- 

 ponding castes of T. vulgaris in size and general features that in 

 practice I have not been able to separate the two species w^th 

 certainty in the absence of imagos. The soldiers of the two species 

 seem to differ in that (a) the tooth on the right mandible ol 

 angustatus is more suppressed, (b) the head is a little more 

 narrowed in front, (c) the sides of the gula more curvate.

This is a species that will have to be treated in the wide 

 sense since there seems to be several forms. Certainly, the 

 soldiers from the Bushveld of the Transvaal are not only larger 

 than those from elsewhere but the nests they come from have 

 the turrets around the airpits uniformly more massive than 

 any seen elsewhere. Unfortunately neither winged imagos nor 

 breeding pairs have yet been obtained in company with the 

 larger headed soldiers so it is not possible to say whether this 

 geographical variant represents a form or is sufficiently different 



♦The elevations are given In brackets, the date upon which 

 imagos were captured on wing are given and all refer to flights 

 during daylight, e.g. from early morning to dusk, just after or 

 during rain.
