The present paper enumerates the twelve known species of 
Japanese Aphelininz, described by Howard, Ashmead, Fitch, 
Girault, and Silvestri, and two new species, which are described 
herein, making fourteen species recorded from Japan in this 
subfamily of the Chalcidide. These minute, coccid parasites 
represent eight genera. 
I am greatly indebted to Dr. L. O. Howard, chief of the 
Bureau of Entomology, of the United States Department of 
Agriculture, for help in the preparation of this paper.
