The materials of the present paper were mostly collected from the 

 neighbourhood of Sapporo by Prof. K. Miyabe and the author. 

 Prof. Y. Niisima has collected also some materials for me. After 

 thorough study of this family of Japan I have found 29 species under 

 19 genera, of which 19 species and 7 genera are new to science. 



The life -histories of this group of insects are very complicated and 

 about the details of them I shall wait for future study. On this 

 occasoin I wish to express my cordial thanks to Prof. K. Miyabe and 

 Prof. Y, Niisima, by whose permission I have thoroughly, examined 

 many valuable specimens. Mr. J. Nishiya of Aomori and Mr. T. 

 Ogasawara of Iwate have collected some Pemphigid -species for me, for 

 which my thanks are due.
