NEW SPECIES OF FURCOMYIA (TIPULID^). 



BY CHAS. P. ALEXANDER, ITHACA, N. Y.^ 



The crane-flies herein characterized as new are, with one exception, 

 Neotropical forms. There have been described by previous writers 15 

 species of South American Limnohini that I have no hesitation in referring 

 to the genus Furcomyia { = Dicranomyia oi authors). With the single 

 exception of j^. mucosa End. (Ecuador), the forms are Chilian or Pata- 

 gonian, and are species named by Macquart,^ Blanchard,^ Philippi* and 

 Bigot.'- No species have been mentioned from the various countries of 

 Middle America, and it is probably because of this fact that so many of 

 the forms received proved to be novelties. 



The material included is the property of Eastern Museums, as follows : 

 U. S. National Museum, received through Mr. Frederick Knab, and the 

 American Museum of Natural History, received through Mr. J. A. 

 Grossbeck. I express my sincere gratitude to both of these gentlemen 

 for their kind help in this respect.
