When we remember that the taxonomy of our Japanese 

 termites has been in a somewhat chaotic state, as is clear from 

 the preceding, this paper of Dr. Holmgren is an extremely valu- 

 able one. For the first time, our rich termite fauna has been 

 introduced to the workers in Europe and America, placing them 

 on a sound taxonomic basis so essential for comparison with 

 forms occurring elsewhere. We accord him our sincere thanks 

 for his great service in this regard. 



Subsequently, I published a paper (1) concerning Holmgeen's 

 « Termiten Japans." In this paper, I made a complete list of the 

 Japanese termites known up to the time, referring all the species 

 mentioned by Japanese workers to those described by Holmgren. 

 I also proposed to adopt the specific name in order of priority. 



In 1913, in Ms great work (6) on the termites of the Oriental 

 Region, Holmgren has given full descriptions of twelve Japanese 

 termites which he recorded in his previous paper (5). But here, 

 Coptotermes formosce was changed into Coptotermes formosanus and 

 Leucotermes speratus was referred to the subgenus Reticulitermes, which 

 he newly established. Yano (8) and Oshima (9, 10, 11) have publish- 

 ed a further instalment of their work. Other investigators, such as 

 Y. Nawa, U. Nawa and Nitobe also have written many papers on 

 our termites, mostly regarding their distribution and habits. 



The works so far mentioned are those most important for 

 the systematic study of the Japanese termites. In fact, there are 

 other records of termites written in Japanese, but they may be 

 omitted here as foreign to our present purpose. 



The study of the Japanese termites was first undertaken by 

 myself at the suggestion of Prof. Watasé in 1910. In the subse-
