elusive that the condition can be stated definitely at this time. 
The males (speciosa) are very light colored, yellowish; the females 
(fuliginosa) are dark l^rownish 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 pupa? 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 laboratorj^, and both specimens emerged on May 23, 
1913, one a male speciosa, the other a iemale 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 Jasciata Loew; Berliner Entomologische Zeitsehrift, vol. 7, p. 279, 
1863 (non Tipula fasciata Linnseus, 1767). 
The Loewian name, fasciata, is a primary homonym of that of 
Linnaius, 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. u. 
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.
