The Tipulidae of the island of Saghahen, separated from the 

 Coast Province of Eastern Siberia only by the narrow Gulf of Tar- 

 tary, show notable affinities with the mainland. The following 

 Tipulidae taken in Siberia by Professor and Mrs. Cockerell on 

 their trip are also known from Japanese Saghalien (Karafuto) : 

 Limonia Jcarafutonis Alexander, Dicranomyia immodestoides Alex- 

 ander, D. spinicauda Alexander, Rhijndia maculata Meigen, R. pul- 

 chra sej)tentrionis Alexander, Limnoj)Mla nemoralis (Meigen) , variety, 

 Helohia Tiyhrida (Meigen), Tvpvla latemarginata Alexander, and T. 

 huho Alexander. This constitutes nearly one-half of all the non- 

 endemic species taken, but it should be noted that all of the species 

 listed have a wide range, either southward through the Japanese 

 islands, throughout the Palaearctic Region, or, in the cases of RMpi- 

 dia maculata and Helohia, occurring throughout the Holarctic Region.
