OBSERVATIONS ON SOME SOUTH AFRICAN TERMITES. 445 



Antennas yellow; whip-like; much as with transvaal- 

 •ensis ; about 25 to 29 joints ; joint III larger or smaller than 

 IV. 



Post-genee as with transvaalensis, but mottled with 

 brown. 



Cxula scoop-shaped ; with sides of free blade much upturned, 

 straight ; distal margin straight, anterior lateral corners 

 oblique. 



Thorax. — Pale yellow or yellow with median patches of 

 red-bi*own on each shield. 



Pronotum arched ; cephalic margin entire ; processes 

 deflected, projecting forward and not outward, not incised 

 behind; sides straight; tapering; caudal margin slightly 

 incurvate, nearly straight. 



Mesonotum broadly oval, narrower than pro- and meta- 

 notum ; caudal margin slightly truncate. 



Metanotum short and broad ; broader than pronotum ; 

 widest behind ; sides nearly straight, oblique and diverging ; 

 caudal margin three-sided, all three edges straight or broadly 

 incurvate. 



Legs pale brown-yellow. Tibia of I with 2 to 3, II with 3 

 to 4, and III with 3 spurs. 



A bdomen. — Yellow. 



Worker. 



Measurements. — Head-width 2 to 3*5 mm.; total length 

 6 to 10 mm. 



The worker of these species is much like that of pretori- 

 ensis, but presents a lower length-range, and the frontal 

 depression of the frons is very shallow. 



Hab. — Orange Free State; Lovat, Tha'banchu. 



Reported as very destructive to veld grass during the 

 drought of 1914. The field series collected at Tha'banchu in 

 August, 1914, contains an obese worker-like creature, larger 

 than the soldiers with a rounded yellow head and pale yellow 

 body. This is probably an immature imago.
