Locality.— Botel-tobago, Formosa ; Little Botel-tobago, Formosa. 



Nom. Jap. — Mizokashira-shiroari. 



Note. — Oshima (8) has recorded the termite from Botel-tobago 

 identifying with an African species Termes (?) canalifrons Sjöstedt i:> 

 and transferring it to the genus Paratermes, which he newly founded 

 upon this single species. Perhaps he has overlooked the fact that 

 Termes (?) canalifrons was already changed into Arrhinotermes 

 canalifrons by Wasmann 15 and others. Holmgeen (5, 6) described 

 it as a new species giving the name of Arrhinotermes japonicus. 

 I (1) have already adopted the name given by Holmgren, rectifying 

 Oshima' s mistake in using Paratermes canalifrons (Sjöstedt) for 

 this termite. Eecently, Oshima (9, 10) also adopted Holmgren's 

 specific name. 



So far as I know, this species is very limited in its distribution. 

 We have found several lots in decayed trees without forming any 

 regular nest in the above mentioned islands, but we have no 

 knowledge of their occurrence from anywhere else. The colony 

 is rather large, composing of larvœ, workers, soldiers and ergatoid 

 forms. The winged form is not known.
