class of kings an d 



queens, which have 



wings until after the 



marriage flight. At a certain time in May 



the males and females from the various 



colonies fly forth to mate, and thus a breed- 

 ing takes place between 

 colonies. Only a few 

 of the pairs, however,

 new colony. The queen, after she is estab-

 the abdomen becoming immensely swollen 

 and elongated to fifteen centimetres with 

 the eggs which are about to be laid. In 

 trojjical countries the termites are troulile- 

 some to man by injuring trees and devouring 

 the woodwork of houses.
