REVISION OF THE JAPANESE TERMITES. 105 



is generally composed of a large number of individuals and lives in 

 a large round underground nest with many diverging subterranean 

 tunnels arising from it and reaching the objects of attack. It has 

 been stated by Oshima and Nawa that the king and queen were 

 found in certain nests, excavated by them. The winged forms 

 swarm in May, June or July. The soldiers are relatively numerous, 

 and are characterized by a habit of secreting milky fluid in drops 

 from a foramen on the forehead.
