 1914. Tipula insulicola Alexander, Can. Ent., xlvi, p. 211. 



The original description of this species was based on a single 

 alcoholic female from the vicinity of Tokio. In the present 

 collection the male sex was represented by three specimens, one 

 of which is here made the allotype. 



Allotype.— d', Meguro, Tokio, Japan, May 14, 1919, (R. 

 Takahashi) . 



Male. — Length, 11.5 mm.; wing, 11.3 mm.; antenna, about 5 mm. 



Similar to the female, differing as follows: Antennae elongate, if bent 

 backward extending to beyond the base of the abdomen. Male hypopygium 

 with the ninth tergite very high, the caudal margin produced into a long, 

 compressed blade whose margins spread out laterally, this conspicuous med- 

 ian lobe being generally similar to the condition found in the Nearctic T.
