The Termites of South Africa 105 



Remarks: According to Silvestri (1914) the major soldier 

 herein described should be that of A. latinotus Holmgren. Quite 

 similar m.ajor soldiers and minor soldiers also accompany a series 

 of imagos that I have from Elizabethville, Belgian Congo. These 

 Congo imagos have very much the same measurements as those 

 ascribed to latinotus but the king and queen from Xinavane seem 

 to differ widely from them in having much smaller ocelli, the 

 loner diameter not being more than 0*17 whilst Silvestri gives the 

 long diameter of the ocellus of latinotus and crucifer as 0-45 

 and 0* 50 respectively. 



The Congo imagos differ from the king and queen of lebom- 

 hocmis inasmuch as the heads of the former exhibit the same 

 median keel and sculpturing that is exhibited by Allodontermes 

 schulizeit a feature wanting in the local insects. 



Associated with a number of soldiers and workers collected 

 at Messina I have found two smaller soldiers. These have every 

 appearance of belonging to Ancistrotermes but the labrum extends 

 over the greater part of the mandibles. In some respects they 

 appear to agree with the description of Microiermes cavithorax. 

 I append a description of these two soldiers leaving their position 

 for the present undecided. 



Head yellow, sub-circular in outline, as wide as long, sides 

 plainly constricted between antennal fossae and articulations of 

 mandibles; quite different in shape from major and minor soldier 

 described above. Mandibles brown, not as long as head (5*7) 

 relatively straight, fine v/ith inbent tips. Labrum relatively long, 

 reaching over greater part of mandibles. 



Antennae XIV jointed; joints III, IV, V increasing or IV 

 somewhat the shorter. Head with mandibles 1-15 to 1 • 1 8 ,- 

 head length 0-7; headwidth 0-7; mandibles 0- 48 to O- 52.
