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

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

 One of them was collected at Rokugo, Pro\^ 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. Dr. 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.
