Note. — This is the commonest of all the Japanese termites, 

 being found in the greater part of the country ; wherever dead 

 wood is present, it is likely to be found there. The first descrip- 

 tion of this termite was given by Kolbe (1). Oshima (1) recorded 

 that not only this species but also the American species Leucotermes 

 flavipes (Kollar) is to be found in Japan, his specimens being 

 secured from Tokyo and Taihoku, Formosa. Other writers such 

 as Srtraki (1, 2), U. Nawa (3, 5) and Nitobe (1) seem to have 

 accepted the Oshima' s view. But in opposition to them Yano (5, 

 6, 7) accepting Holmgren's statement and according to his own 

 observations maintained that, those specimens referred to as Leuco- 

 termes flavipes (Kollar) by them belong to Leucotermes speratus
