directed inwards, cutting margin below tooth serrate, if not worn^ 

 Right with a coarser triangular tooth below half length, the 

 upper edge of which curves into the margin of the apical. 



Antennae XVII. jointed, joint IV. coarser than III. and V., as 

 large as VI. or plainly longer than either III., V. or VI. ; IV. 

 tending to subdivide. Keadwidth 3*5 to 5 • ; head with mandi- 

 bles 5*7 to 6*4; head without mandibles 3-8 to 4*3. 



Intermediate Soldier : Like major, head thick but less robust. 

 Headwidth 2*6 to 2*7. Antennae as with major.

 dibles. Sculpture of frontal area not nearly so pronounced. 

 Mandibles not so coarse but with similar dentation. Antennae 

 XVII. as with major. Headwidth 2-1 to 2 • 3 ; head with man- 

 dibles 3*9 to 4 • 4 ; head without mandibles 2 • .5 to 2 •- 7. 



Remarf(s: The specimens upon which this description is based 

 were sent to me from Okahandja, Damaraland, by Dr. B. 

 Sch wonder in 1918. Owing to the fluid in which they were 

 preserved, the bodies are much shrunken and discoloured. I 

 have also one major soldier and several minor soldiers with a 

 fev/ workers that I take to be this species from Ovamboland, 

 These soldiers have reddish yellow heads and somewhat darkened 

 bodies and yellow legs. The major exhibits a small but distinct 

 black eye spot. The workers are relatively small with yellow 

 heads.
