540 AUSTRALIAN TERMITID^K, 



slightly connected towards the tips with irregular cross veins; 

 median nervure fine, but irregularly branched at the tip; sub- 

 median with a great number of fine bifurcated oblique nervures; 

 the whole wing reticulated with furrows and ramulose veinlets. 



Hagen placed in this subgenus of Ternies three species from 

 Cuba, Surinam, and Brazil. A fourth species was described liy 

 Brauer from Australia. The members of the Australian species 

 live in communities like Calotermes. On account of the irregular 

 veins between the costal and subcostal nervures I have j^laced 

 them in a separate subfamily.
