NEW OR LITTLE KNOWN CRANE-FLIES FROM 

 NEW ENGLAND. 



BY CHARLES P. ALEXANDER. 



The two species described as new in this paper are character- 

 ized at this time in order to be available for the forthcoming list 

 of the Diptera of New England. Records of the capture of two 

 other flies that had been unrecorded from thes,e States are added. 

 The unique type of Tipula insignifica was included in material 

 kindly submitted to me for examination by Mr. C. W. Johnson, 

 to whom my sincere thanks are extended for many kindnesses 

 in the past. 



Family Anisopodidae. 



Subfamily Axymyiinae. 



Axymyia furcata McAtee. 



Eupeitenus atra Coquillett {nee Macquart), Ent. News, vol. 20, p. 106, text- 

 fig., 1909. 



Axymyia furcata McAtee, Proc. Ent. Soc. Washington, vol. 23, p. 49, 1921. 



Axymyia furcata Shannon, Proc. Ent. Soc. Washington, vol. 23, p. 50-51, 

 1921. 



This rare anisopodid fly had been taken hitherto only in New 

 York, Pennsylvania and northern Virginia. The writer captured 

 a single female specimen on the eastern slopes of Mt. Toby, 

 Franklin Co., Massachusetts, May 17, 1924. Down this slope 

 of Toby a large mountain stream pours over densely moss- 

 covered boulders, reaching the lower levels near the Central 

 Vermont Railroad siding near Montague. The specimen of 

 Axymyia was swept from vegetation along this stream, at an 

 altitude of approximately 600 feet, where it was associated with 

 various Tipulidae, notably small swarms of Ormosia nubila 

 (O. S.) and Ormosia m.eigenii (O. S.) and numerous scattered 

 individuals of Tricyphona vernalis (0. S.) and Tipula iroguois 

 Alexander. When at rest in the net, the fly resembles a small 

 leptid or a species of Anisopus. Like the species of Tipulidae 

 with which it was associated, this fly is presumably a member of 

 the vernal Dipterous fauna of the Canadian-Transition life-zone.
