HE VISION OF THE JAPANESE TERMITES. 51 



Locality. — Kuraru, Formosa ; Ishigakijima, Loo-choo ; Bonin Is. 



Nom. Jap.— Katan-shiroari. 



Note. — This termite was first collected by myself in a fallen 

 trunk of Bisclioffia javanica Blume at Ktirarn, Formosa. In the 

 lot were fonncl many workers, nymphs and a single soldier, but 

 no winged forms. Holmgren's description of Calotermes (Glypto- 

 termes) hozawce (5, p. 118 ; 6, p. 53) was based on these speci- 

 mens. Afterwards Inamura found the winged forms in addition 

 to soldiers and sent them to Oshtma, who described this species 

 before Holmgren's paper (5) made its appearance. I secured 

 specimens of this form from Loo-choo and the Bonin Islands, the 

 former through the kindness of Mr. Iwasaki and the latter 1 of Mr. 

 Daido, The lots sent me contained winged forms as well as nymphs, 

 soldiers and workers ( ? ). Some of the specimens from the Bonin 

 Islands, however, seem to be somewhat different from the Formosan 

 ones respecting the size of imagines, the colour and size of soldiers* 

 head, etc. But these differences are rather that of degree than of 

 kind. This is borne out by the fact that the Loo-choo specimens 

 represent a form intermediated between those of the Bonin Islands 

 and of Formosa. 



This species lives in decayed logs, fallen trunks, etc., forming 

 narrow tunnels in them and not building a regular nest. The 

 colony is small, the majority of individuals being workers and 

 immature nymphs with very few soldiers. 



Subgenus Cryptotermes (Banks).
