Note. — This species was first mentioned in Holmgeen's paper (3) 

 and fully described in his later ones (5, 6). Oshima also recorded 

 this termite under the name of Calotermes kotoensis (8, p. 56). 



This termite was found in old stumps, dead trunks, timbers, 

 decayed portions of the living tree, etc. It does not construct a 

 regular nest, its colony being rather small, mainly consisting of 

 workers or immature nymphs and very few soldiers. At Botel- 

 tobago early in June, I often met with the winged forms in the 

 nest, and with those flying after sunset. 



Oshima (9, 10, 11) described a new species Calotermes (Crypto- 

 termes) ogasawaraensis from the Bonin Islands, distinguishing from 

 Calotermes {Cryptotermes) kotoensis, showing several differences. The 

 differences, however, by which the two species have been divided 

 seem to be not constant, being rather variable in different in- 

 dividuals. Perhaps, Oshima has overlooked this fact in examining 

 only a few specimens. I have examined carefully many specimens 

 from the same locality, comparing them with those from other localities 

 and came to the conclusion that Calotermes (Cryptotermes) ogasawaraensis 

 Oshima is but a synonym of Calotermes (Cryptotermes) kotoensis Oshima.
