Although the images of belUcosus have many points of re- 

 semblance to those of natalensis they are nevertheless consistently 

 different. The heads differ in general appearance because that 

 of belUcosus is shorter, the eyes more prominent and the epistome 

 (clypeo-basal) more narrow. Further, both the eyes and ocelli 

 of belUcosus are more convex than those of natalensis and the 

 ocelli of the former are plainly closer to the e5Ts than are those 

 of the latter. Apart from the head, the pronotum of belUcosus 

 is wider in proportion to its length than is that of natalensis, the 

 front margin plainly emarginate whilst with natalensis it is straight 

 or but negligibly emarginate, the anterior lateral corners are 

 angular and usually somewhat spread out, wnth natalensis these 

 corners are rounded. 



As between the major soldiers of the two species whilst the 

 sculpturing of the frons will at once separate the two, the soldiers 

 of belUcosus are also strongly individualized by the relative short- 

 ness of their mandibles, the more crooked condition of the left 

 mandible and the almost parallel sides of the head.

Winged Imago : Whole insect dark chestnut brown to black 

 above with pale reddish hyaline wings and large body. Head 

 dark chestnut brown, usually vinous behind; clypeus as dark as 

 rest of head, mandibles brown or bases sometimes vinous ; eyes 

 black but not contrasting with head colour, antennae dark brown ; 

 labrum yellow. Pronotum black brown with yellow cross and 

 yellow spots near anterior lateral corners. Meso- and meta- 

 notum almost wholly as dark as pronotum. Tergites of abdomen 

 black brown. Below usually chestnut brown, sometimes yellow- 

 ish brown ; tibiae darker than coxae and femora. Head with a 

 well defined median carina, sculpture of frons much like that of 

 natalensis and hellicosus; clypeus relatively narrow and some- 

 what inflated; eyes somewhat flat, as with natalensis; ocelli not 

 prominent, oval facing forward, as with natalensis, about long 

 diameter from eye. 



Antennae XIX. jointed : III. as long as IV. and V. together. 

 IV., v., VI. subequal, gradually increasing. 



Pronotum a little wider than head with eyes (19:18) ; front 

 margin >shallowly emarginate, anterior lateral corners rounded, 

 sides oblique, flatly curvate, hind-margin flatly incurvate; not 

 quite twice as wide as long (19:10). 



Mesonotum with hind margin plainly incurvate, that o£ 

 metanotum flatly incurvate, almost straight.
