Odontoiermes iransvaalensis (Sjost.) (1904). 



In general characters the imago is much like the imago of 

 badius but differs sharply in the dark smoky brown colouration of 

 the wings. 



The soldiers also bear a strong resemblance to those of hadius 

 but the two species can be at once separated by the difference 

 in the dentation of the right mandible. In iransvaalensis the 

 right mandible exhibits a clear cut step-like tooth, this is almost 

 as prominent as that on the left and the upper margin is at a 

 right angle with the inside edge of the apical. In badius the 

 tooth of the right mandible is not step-like nor is it as prominent 

 as the tooth on the left, further the upper margin slants down 

 from the inside edge of the apical.

Odontotermts okahandjae sp.nov. 



Imago and worker unknown, latter said to be very destructive 

 to plants and timber of houses. 



Soldier major: Head strikingly massive and thick (1'5 mm.) 

 strongly characterized by a coarse ridge extending from the base 

 of one mandible to that of the other. Head only a little longer 

 than wide ; much wider and thicker behind ; sides flatly curvate 

 and tapering to mandibles : hind margin broadly curvate ; cut 

 off in front by transverse ridge. Crest of ridge bisinuate, front 

 sloping to labriim, behind sloping into a relatively deep triangul- 

 ar depression ; in the centre of the depression a short distinct 

 median carina. Labrum relatively short, obtusely triangular. 

 Mandibles relatively short, about half the length of the head; 

 massive, wide, with inbent tips; left with a distinct but rela- 

 tively small pointed triangular tooth at about half length, tootli
