JAPANESE COLLEMBOLA. 



BY JUSTUS WATSON FOLSOM. 



The few forms with which this piiper deals will interest 

 eiitomoloo:ists because nothini!: has hitherto been recorded 

 concerning the Collembola of Japan. My friend, Dr. 

 Seitaro Goto, was so good as to collect three species for 

 me in Tokyo, which were kindly brought by Professor 

 Mitsukuri, of the Imperial University. Thanks to the 

 care with which the specimens had been killed and pre- 

 served, they arrived in excellent condition and, therefore, 

 were not difficult to study. All these species prove to 

 be new and are here named AchoriUes commiuiiti, Xenylla 

 longicauda and Seira japonica. Many of the types have 

 been deposited in the Museum of Comparative Zoology 

 at Cambridge, Mass.
