UNDESCRIBED SPECIES OF JAPANESE CRANE-FLIES. 



(TIPULIDiiE, DIPTERA) 



By Charles P. Alexander, Ph. D. 



The species of crane-flies herein described as new were 

 included in some extensive and highly interesting collections 

 made in the vicinity of Tokio by Mr. Ryoichi Takahashi, 

 during the years 1918 and 1919. The station "Saitama, " 

 refers to Chichibu, in the province of Saitama, a mountainous 

 locality about fifty miles from Tokio. The types are preserved 

 in the collection of the author. I am greatly indebted to Mr. 

 Takahashi for this very valuable series of Japanese Tipulidas.
