L. noveboracensis is common, and apparently widely distributed 

 in the North. The type locality is in the Southern Adirondack 

 Mts. (N. Y.). The species is common about Ithaca, N. Y. (Coy 

 Glen), and there are specimens in Dr. Needham's collection 

 labelled "Walnut Lake, Mich., July 8, 1906." It has probably been 

 confused with L. quadrata in collections. The figure in Dr. Need- 

 ham's Report on the Crane-flies of New York (23d Rept. of the 

 N. Y. State Entomol., pi. 18, fig. 6) is not quadrata but belongs to 

 this new species. The specimen of L. luteipennis, mentioned by 

 Osten Sacken (Monographs, etc., IV, p. 218) where he says *T 

 possess a specimen without petiolated (second) posterior cell in 

 both wings" may possibly belong to noveboracensis.
