A new Dilar species from Japan (Neur. Plan.). 



By Waro Nakahara, Tokyo, Japan. 



The genus Dilar was not known in Eastern Asia until Navas 

 described a species, D. septentrionalis (Rev. Russ. d'Entom., 

 xii, pp. 420-21, 1912), from Siberia, although eleven species of 

 the genus were recognized from various parts of the world 

 before that time. 



The new species which is described in the present paper is, 

 therefore, the second species of the genus in the region just 

 referred to.

 are more or less suffused with fuscous, joints in the middle of the 

 antennae are much more elongated than those near the base or near 

 the apex ; lateral appendages of nearly equal length present on third 

 to eighteenth joints.
