JAPANESE COLLEMBOLA. Part U* 

 By Justus Watson Folsom. 



Received November 1, 1898. Presented by Samuel II. Scudder, November 23, 1S98. 



The interesting collection upon which this paper is based was made 

 by Prof. C. Ishikawa, of the Agricultural College at Komaba, Tokyo, 

 and was most generously given me to study by Professor Packard, to 

 whom my sincere thanks are due. All that has hitherto been published 

 upon the Collembola of Japan is a short article by myself, in which three 

 new species are described. The present paper deals with eleven species, 

 of which six species and one variety are new. In accordance with the 

 wishes of Professor Packard, a series of specimens has been given to the 

 United States National Museum at Washington, D. C, and another to 

 the Museum of Comparative Zoology at Cambridge, Mass. 



My friend, Dr. C. Shaffer, of Hamburg, has materially assisted my 

 studies by sending identified examples of European Collembola, as well 

 as valuable notes. Mr. Samuel Henshaw has given me many useful 

 suggestions, and freely permitted me to study the collection of the 

 Cambridge Museum.
