In the course of my study on the family of Coccinellklae in Japan, I have 

 found that there are three new species belonging to the subfamily Coccinellinae. 

 One of them was collected at Rokugö, Prov. Musashi by Mr. S. Mitsuhashi and 

 the others captured by the writer in the various localities. The present short 

 paper is intended to describe these new species. 



I wish here to express my hearty thanks to Prof. ])v. S. Matsumura and to 

 Mr. H. Okamoto, for the valuable suggestions and kind directions. My obliga- 

 tions are also due to Messrs. S. Mitsuhashi, Y. Yamada and S. Hirayama, who 

 have had the goodness to allow me to make the free use of their collections of 

 this family.
