Description or Phryganea imperial's n. sp., with 

 Remarks on the generic characters of 

 Phryganea and Neuronia. 



BY WARO NAKAHARA. 



In a small lot of Trichoptera presented by Mr. Motojiro Suzuki to 

 me,, there is included one specimen of a Phryganeid which is closely 

 allied to these magnificient species such as Phryganea regina f M' 

 Lach.), but is evidently undescribed. As I* have lately revised Japa- 

 nese species of this family it is with much interest that I add this 

 new species to our fauna.
