A study of both major and minor soldiers shows that the 

 length of the insect has but little relation to the length of 

 the head. 



With regard to the total length of major and minor soldiers, 

 the major soldiers in my collection have a range of from 13 to 

 18 mm. and the minors of from 8 to 12 mm. A purely mis- 

 cellaneous series of measurements of 155 major and 68 minor 

 soldiers gives the following analysis : 



The following tables, showing the range of variation, are 

 based upon the measurements of 10 major soldiers and 10 

 minor soldiers, or 100 insects in all, from five widely separated 

 nests in regions having very different climatic conditions 

 (comprising at least four of the floral regions pi'oposed by 

 the late Dr. Bolus). 



No. 1 nest : Mount Edgecombe, Natal, at an elevation of 

 201 ft. and in coast bush country. 



No. 2 nest : Winterton, Natal, elevation 3354 ft., in grass 

 veld. 



No. 3 nest: Pretoria, Transvaal, elevation 4471 ft., located 

 below a house.
