 Norn. Jap. - Mizuki-hirata-abura. 

 In Europe as well as in America this species has been described 

 under different names, for it attacks very diverse kinds of plants, nam- 

 ely in the spring it spends its first generation on Cornus macrophylla, 

 C. sanguinea or the other allied species and in summer migrates to the 

 farms and attacks the root» of the different kinds of the graminous 

 plants. Prof. C. Sasaki has also described this species under two 

 different name*, but they are most probably the same species. As the 

 individuals on the Cornus-plant are much larger and differently colo- 

 ured, even morphologically somewhat changed than those on the roots 

 of the graminous plants, it is a natural mistake for any entomologist to 

 treat this insect under a different species, even under a different genus.
