This species presents at tlie same time a near relation to 

 (S*. Kunckeli, but the structure of the vulvar scale is very different 

 from that of Kunckeli. Judging from the data above mentioned 

 I regard this insect as a quite distinct species and make it known 

 by the name above given. The question remains still open, untill 

 the male is obtained. 



Three female specimens were examined in the late autumn of 

 this year by the author in the collection of Mr. Shibakawa.

 than the fore wing, having equal breadth throughout the length, 

 . with 6 antenodals and 7 postnodals , the first two of the latter

 It is very interesting fact to find such a species belonging to 

 the genus Planiplax in Japanese empire.
