The Termites of South Africa 79 



Measurements : Body, with head extended 25; body with wing* 

 47; forewing with stump 39, without stump 37; span 82; head- 

 width across eyes 3-9 (Wings and bodies of males sometimes a 

 little shorter).

 Tzaneen, Mokeetse). 



Macroiermes waierbergi (Fuller). 



= Termes n^aterhergi Fuller (1915, 1920), soldiers and 

 workers. 



Imago : In size and general appearance much like the imago 

 of M. swaziae but differing at a glance in the more prominent 

 upturned ocelli and the relatively long distance these are re- 

 moved from the eyes, more than twice the long diameter. Also 

 differing in the clypeus being yellow, the median ridge of the 

 frons less decided, the antennae paler, and the eyes more convex. 

 Pronotum plainly more than twice as wide as long (21:9) ; front 

 margin emarginate, anterior lateral corners somewhat acute; 

 much like those of hellicosus; a little wider than head across 

 eyes. Meso, and metanotum with hind margins about equally 

 and flatly incurvate. Sternites of abdomen with distinct lateral 

 yellow spots. 



Body with head extended 24; body with wings 47; forewing 

 with stump 40 ; without stump 38 ; Span 84 ; headwidth across 

 eyes 4 • 3. 



Localities: TransvaaL: Nylstroom, Warmbaths and northern 

 slopes of Magaliesbergen. 



Macrotermes usutu sp.n. 



Imago: Only one queen is known to me. This stands very 

 close to M. sTvaziae. A comparison shows that the ocelli of usutu 

 are shorter and narrower than those of swaziae, therefore 

 somewhat further from the eyes; the head and thorax is 

 more polished; the anterior lateral corners of the pronotum more 

 hollov/ed out. 



Pronotum as wide as head. Headwidth 4.0. 



Major Soldier: As large as that of M. swaziae, the head how- 

 ever reddish yellow and not decidedly sculptured on frons; body 

 and legs yellow. Head massive; flatly arched; sides tapering 

 but not decidedly, somewhat straight; widest behind. Frontal 

 area flatly depressed, sculpturing faint obscurely resembling- 

 that of if. hellicosus and M. swaziae.
