OBSERVATIONS ON SOME SOUTH AFRICAN TERMITES. 439 



AntennjB yellow ; whip-like ; distal series not tapering as 

 conspicuously as in transvaalensis ; composed of 27, 28, 

 29, or 30 joints ; III, IV, V subequal, annular, and the three 

 narrowest and smallest; VI and onwards increasing in length 

 and width ; width from VII or VII [ constant up to the last 

 4 to 6 apical joints which taper veiy little ; lengths reaching 

 maximum at the twelfth to fourteenth joint from apex, apical 

 joint always shorter than penultimate and often decidedly 

 narrower. 



I strong, cylindrical, furnished at apex with distinct whorl 

 of spines ; more than twice the length of II and one third 

 wider (length range 400 to 500 fx). 



II strong, cylindrical, nearly as wide as long; wider than 

 any succeeding joint ; furnished with a whorl of bristles at 

 apex and with scattered bristles over apical half (200 to 230 fi) . 



III short, annular, less than half the length of II ; with a 

 single apical row of bristles; anchylosed to II (70 to 100 /u). 



IV and V similar to III and 



VI annular; longer than V; with apical bristles (100 to 

 ISO fi). 



VII larger than VI ; with apical bristles and often with a 

 second whorl (110 to 150 fx) ; first few succeeding segments 

 globose ; rest obconic ; apical series more elongate, with 

 almost parallel sides (130 to 210 /x) ; VIII onwards, with two 

 whorls of bristles and scattered bristles. 



Apical joint shorter than penultimate, sides parallel, apex 

 convexly truncate (175 to 200 /li). 



Post-gena3 as with transvaalensis. 



Gula scoop-shaped; as with transvaalensis, but free 

 blade with noticeably chitinised and much up-turned sides ; 

 concolorous with post-genas. 



Thorax. — Almost uniformly reddish-brown, paler than 

 head ; with dark paired brown spots upon meso- and 

 metanotum ; agreeing in structural details with transvaal- 

 ensis except that (1) the processes tend to be more rounded 

 apically and more lateral in direction of cephalic edge, and 

 (2) that the anterior margin of the pronotum is entire.
