Note.— This termite was first described by Shiraki (1) under 

 the name of Coptotermes formosanas from the specimens obtained 

 in Formosa. Oshima also recorded it firstly (2) adopting the Shiraki's 

 specific name, secondly (3, 6, 7) identifying with Termes gestroi 

 Wasmann, and lastly (8, 9, 10) reverting back to the first. Matsu- 

 mura (4) seems to have identified it with the Australian species 

 Coptotermes raffrayi Wasmann. X) Holmgren (2, 3, 5) has given the 

 name of Coptotermes formosce to this termite. But, in his later 

 paper (6), this specific name was changed into Coptotermes 

 formosanus of himself. 



Here I described it adopting the Shiraki's nomenclature. 



Coptotermes formosanus is our most destructive species, widely 

 distributed over the south-western half of Japan. In most cases 

 of damages said to be due to white ants in the above mentioned 

 regions, one is sure to meet with this species. Not only wooden 

 buildings, furnitures etc, but also logs, old stumps, decaying 

 portions of living trees, etc. are equally attacked by it. The colony 



1) That Coptotermes raffrayi Wasmann is a synonym, of Coptotermes lacteus (Fboggatt) is 

 indicated in Holmgren's paper (3, p. 74).
