Genus TERMES* Linn. 

 *= Odoniotermcs s.lat. Holmgren, not Termes Holmgren 

 (1912). 



For reasons that have already been sufficiently stated, Holm- 

 gren's genus Odoniotermcs s.lat. must give way to Termes. I 

 propose however to constitute Odontotermes as a sub-genus of 

 Terries somewhat but not entirely in the strict sense of its defi- 

 nition by Holmgren . 



*In the key to images given in Part I. Macrotermes should 

 have been further distinguished ifrom Termes and Allodontermes 

 by the condition of joint HI. of the imago antennse. This is 

 longer than IV. in Macrotermes and as long as or shorter than 

 IV. in Termes and Allodontermes.
