On the Osmylinae of Japan. 



By 



Waro Nak.ili.ara. 



In order to supplement in a way the works of MacLachlan, 1 * and 

 Navâs'-' 5 on the Osmylinae of this part of the world, it is proposed to 

 give in this paper an account of all the forms of that subfamily 

 known to me from Japan (not including Formosa). Though the 

 material which came under my examination cannot be [said to be 

 extensive, I have thus far been able to recognize fourteen species as 

 occurring in the region referred to. Of that number, seven seem to 

 be new to science and one to be new to Japan, while the remaining 

 six represent all those species which have hitherto been recorded from 

 that country. Here I let follow the list : 



FAMILY HEMEROBIIDAE. 



Subfamily Osmylinae. 

 Tribe Sisyrini. 



1. Sisyra japonica n. sp. 3. Sisyra Yamamurae n. sp. 



2. 5. ozenumana n. sp.

4. Berotha [Isoscelipteroti) Okamotonis n. sp. 



Tribe Osmylini. 



5. Spilosmylns tuber culatits 7. Spilosmylus flavicornis 



(Walker). (MacLachlan). 



6. S. nikkocnsis (Navâs). 8. S. immaculatus n. sp.
