elusive that the condition can be stated definitely at this time. 

 The males (speciosa) are very light colored, yellowish; the females 

 (fuliginosa) are dark brownish to almost black. This is the first case 

 of dimorphism in the Tipulidse that has come to my notice, but the 

 related species, jejuna Johnson and taughannock sp. n., certainly 

 belong here. 



This evidence of dimorphism in the species that is before me is as 

 follows: a male and a female, taken in copulation, collected at Ira, 

 Summit Co., Ohio, by James S. Hine. A male and a female secured 

 in copulation and actually pinned while still "in coitu, " collected 

 at light, Boston, Mass., June 1, 1914, by H. M. Parshley. The 

 final evidence is the finding of two crane-fly pupae in the debris 

 beneath the nest of a turkey vulture, on Jacksons Island, Md., 

 May 23, 1913, by Messrs. Barber and Shannon. The material 

 was taken to the laboratory, and both specimens emerged on May 23, 

 1913, one a male speciosa, the other a hmiale fuliginosa! 



On June 13, 1914, on Buell Mt., Fulton Co., N. Y., the males of 

 this fly were common on the mountain side in the open shady woods. 

 One female was taken. The males were usually found flying up a 

 tree-trunk, beginning low down near the base of the tree, ascending 

 by a partly flying, partly climbing motion. They were undoubtedly 

 searching for the retiring females, as has been observed in other 

 woodland-inhabiting species, as fragilis and others. 



Tipula hermannia n. n. 



Tipula fasciata Loew; Berliner Entomologische Zeitschrift, vol. 7, p. 279, 

 1863 (non Tipula fasciata Linnseus, 1767). 



The Loewian name, fasciata, is a primary homonym of that of 

 Linnaeus, and the species is herewith changed as above. The insect 

 is very common and widely distributed throughout the Eastern 

 United States and Canada. 



Tipula kennicotti sp. n. 



Coloration grayish; thorax with a single very narrow median 

 brown stripe; wings pale brown with a vitreous band before the 

 cord; male hypopygium with the ninth tergite nearly if not quite 

 fused with the sterno-pleurite; caudal margin of the tergite with a 

 two-lobed median process; pleural appendages, two large flattened 

 fleshy lobes on each side; sternal region profoundly incised; eighth 

 sternite unarmed.
