3. Distribution. 



The species is widely distributed on the southern coast of the Main 

 Island, Shikoku, Kiushu, Hachijo, Riukiu Islands, Formosa and the southern 

 part of China. Considering their habitat, it may be concluded that the 

 species can live in any region where the mean temperature is above 15°C. 

 but not in regions where it is lower than that. 



4. Damages. 



This species does damage to railway sleepers, bridges, fences, etc. 

 The insects are particularly apt to make their nests at the bottom of 

 buildings, whence they creep into cracks in the house, or climb up to the 

 top. They damage dry part of the house as well as the damp. Being 

 highly reproductive, this white ant is far more formidable than any other 

 species. Most of our principal construction woods are attacked by this 

 species, particularly the pine wood. 



This species of ten ' attacks living trees. Pine trees of 1-2 ft. diam. 

 often fall victim to this noxious insect which eats up the centre of the 

 tree. Cherry, willow, ginkgo and camphor trees also often attacked.
