(Kolbe). Afterwards Oshima (7, 8) consulting with Shieaki made 

 a new species Leucotermes ßaviceps out of the very specimens which 

 he formerly called Leucotermes flavipes and those obtained at 

 Botel-tobago. He separated the former both from Leucotermes 

 speratus (Kolbe) and Leucotermes flavipes (Kollab). Holmgren 

 (5, 6) called Leucotermes speratus (Kolbe) or Leucotermes (Reticuli- 

 termes) speratus (Kolbe) all these specimens from various localities 

 of Japan, which had been sent to him from the Zoological Institute. 

 It is certain that Holmgeen had both the specimens from Formosa, 

 which Oshima thought to be Leucotermes flavipes (Kollab) and latterly 

 Leucotermes flaviceps, and those from Botel-tobago, in which Oshima's 

 Leucotermes flaviceps must have been included. It should be mentioned 

 that I had made a careful examination of the lot which were sent 

 to Holmgben, comparing them with the real Leucotermes flavipes 

 (Kollab), kindly sent to Professor Watasé from Dr. Maelatt of 

 Washington D. C. Thus I arrived at the conclusion, similar to 

 that of Holmgeen and Yano, that is, that they are to be identified 

 as Leucotermes speratus (Kolbe), the only Japanese representative 

 of the genus Leucotermes, that Leucotermes flavipes (Kollab) has 

 not so far been found in Japan, and that Leucotermes flaviceps Oshima 

 is but a synonym of Leucotermes speratus (Kolbe). 



This termite lives forming irregular cavities under or in rotten 

 boads, timbers, decayed logs, stumps, fallen trees, etc., and con- 

 structing outside them narrow fragile galleries. Kegular nests were 

 never to be met with. The colony is rather large, generally consist- 

 ing of numerous workers, fewer nymphs, soldiers and larvae. The 

 winged insects swarm on a warm day in April or May. Besides 

 the usual mode of reproduction performed by a king and a queen, 

 neoteinic forms in some cases seem to play the part although I 

 have never met with the neoteinic king. Once I have found in a
