CRANE FLIES FROM THE MARITIME PROVINCE OF 



SIBERIA 



By Charles P. Alexander 



Of the Massachusetts Agricultural College, Amherst 



The crane flies that were taken by Prof. T. D. A. and Mrs. Cock- 

 erell on their recent trip to Eastern Siberia have been submitted to 

 me for determination. Because of the almost total lack of material 

 and records from this region, the collection proved to be of excep- 

 tional interest and furnished several important additions to the 

 incomplete list of the Tipuloidea of Eastern Siberia. In addition to 

 the species recorded in the following pages, Professor Cockerell writes 

 me that he saw, but was unable to capture, a specimen of Ctena- 

 croscelis mikado (Westwood) at Tsuruga, Japan. My sincere thanks 

 are extended to Professor and Mrs. Cockerell, and to the National 

 Museum authorities, for the privilege of studying this series of Tipu- 

 lidae. The types and specimens of all other included species are 

 preserved in the National Collection. 



In order that the known and probable components of the Tipulid 



fauna of Eastern Siberia may be more correctly understood, the 



following list of Regional Species is supplied. In addition, it may be 



well to indicate the occurrence of the European Dictenidia himaculata 



(Linnaeus) in this coastal province of Siberia, an enormous extension 



of the range of the species, which, however, has never been taken in 



Japan. 



REGIONAL SPECIES 



Almost the only Siberian Tipulidae that may be considered as be- 

 ing regional are the following: Tipula hreviceps (Motschulsky)^ 

 from Amurland and few Tipuline crane flies belonging to the sub- 

 tribe Ctenophoraria, described in 1873 and 1S87 by Portschinsky 

 {Ctenophora parva Portschinsky, C. pictipennis Portschinsky, Tany- 

 ptera gracilis (Portschinsky), T. minuta (Portschinsky), and T. 

 siherica (Portschinsky), all from various parts of Siberia, some 

 from the vicinity of Vladivostock.
