 epinotum of the metatliorax are very faintly indicated ; indeed, later-

 Segments themselves have become very nearly fused. 



The soldier has the typical prothorax. On the dorsal aspect 

 the mesonotum. a small metanotiim and the epinotum are distinct; 

 laterally, however, these begin to fuse with the lateral parts and 

 become indistinct. The tegnlae are i)reseut. The episternite and 

 epimerite of the mesothorax have fused with the sternite and are 

 separated from the mesonotum by a faint suture only. In the meta- 

 thorax the epinotum, sternite, episternite, and epimerite have com- 

 pletely fused. 



The worker has the pro-, meso- and meta-thorax distinctly 

 separated dorsally, but tliey have fused with the other parts laterally
