A NEW SUBFAMILY OF TANYDERID FLIES 

 (DIPTERA). 



By Charles P. Alexander, 

 Urbana, 111. 



The family Tanyderidae, which includes the most gen- 

 eralized of the four recent families of crane-flies, has hitherto 

 been represented by a single subfamily, the Tanyderinse. This 

 group has been further subdivided into a number of genera, 

 varying from about six, in the opinion of Dr. Anton Handlirsch 

 and others, to three, in the opinion of the writer. It is with 

 great pleasure that a remarkable new genus and species is 

 here made known, differing so strikingly from all members of 

 the Tanyderinae that a new group of co-ordinate value is 

 required for its reception. 



The distribution of the known recent species of the family, 

 thirteen in number, may be listed.
