REVISION OF KEAECTIC TERMITES. 17 



Wings slender; costal venation distinct, other colorless; margin not 

 ciliate, no hairs on surface; radial sector with several superior 

 branches, and often one or more less distinct inferior branches; 

 sometimes faintly reticulate near apex behind radial sector, not 

 elsewhere; median vein runs parallel to the cubitus and ends near 

 tip, usually in one or more forks ; cubitus rmis out to near tip of wings. 

 Soldier. — Head more or less elongate; mandibles large, armed 

 with teeth, but unlike; clypeus not bilobed; cerci indistinct; tibia 

 with three apical spines; legs short, all femora greatly enlarged; 

 third joint of antennae often enlarged or modified. Originally
