OBSERVATIONS ON SOME SOUTH AFRICAN TERMITES. 449 



a strong, blunt, conical tooth ; margin below second tooth on 

 left once incised. 



Antennas opaque yellow-brown throughout ; not conspicu- 

 ously haired; much like that of transvaa lensis ; about 

 26 to 27 joints ; I particularly long, wider at the apex than 

 the base and with concave sides ; II strong, cylindrical, about 

 one-third the length of I ; III very small ; IV (in some) much 

 larger tlian III and larger than V ; V larger than III, a little 

 shorter and narrower than IV ; VI, VII, VIII equal and the 

 same as VI; basal joints from III onwards are first annular, 

 then moniliform or globose, then short obconic ; the apical joint 

 is elongate oval and the three preceding it elongate obconic. 

 (This pattern is also present in some of the smallest soldiers, 

 but occa^sionally joint III is quite large, larger than IV.) 



Post-gense as in transvaalensis. 



Grula much darker than the post-genae ; scoop-shaped ; free 

 blade with up-curved, parallel sides and convex median 

 region ; distal apex soft incurvate, normally white ; inserted 

 stem half cylindrical, narrower than the blade ; very short 

 and constricted. 



Thorax. — Brownish or reddish-yellow or concolorous with 

 abdomen. 



Pronotuin narrower than the head, in general resembling 

 that of transvaalensis; cephalic margin acutely elevated 

 (45°), almost semicii-cular, entire; sides upbent, margins 

 curvate and tapering behind, hind margin broadly incurvate ; 

 lateral processes somewhat deflected, projecting outwards 

 from bases of cephalic arch at right angles to median line of 

 body ; front margin straight, hind margin curvate, curve 

 continuous- with that of sides. 



Mesonotum narrower than pronotum ; almost oblong ; 

 caudal margin almost straight, but slightly concave at 

 middle ; sides bent, curving inwards in front, outer edges 

 straight and parallel, behind bent inwards at an obtuse 

 angle. 



Metanotum narrower than mesonotum, caudal margin 

 straight.
