472 PROCEEDINGS OF THE ACADEMY OF [Sept., 
ened. Legs with the coxae dull yellow, a little suffused with brown 
on the anterior outer face; trochanters yellowish brown; femora 
dull yellow, the tip narrowly dark brown; tibiae dull yellowish 
brown, soon passing into dark brown; tarsi dark brown. Wings 
grayish subhyaline; stigma moderately indistinct, brown. Venation 
(see Plate XVI, fig. 3); Rs long; cell Mi petiolate; basal deflection 
of Cui and the cross-vein m-cu beyond the fork of M. 
Abdomen with the tergites brownish yellow, the caudal margin of 
each sclerite dark brown, sending a broad median line forward, 
forming a 1-shaped mark; on the apical segments only the median 
vitta persists; lateral margins of the tergites with the anterior half 
grayish, the caudal half dark brown; an interrupted median line 
on the sternites. 
The paratype is quite similar to the type with the following excep- 
tions and additions: antennal flagellum dark brownish black; the 
thoracic stripes very dark brownish black with the ground-color 
light yellow; the pattern on the abdomen is indistinct but indicated. 
Habitat. — -Northern United States and Canada. 
Holotype, 9 , Mt. Washington, N. H. 
Paratype, 9 , Farewell Creek, Southern Saskatchewan, Canada; 
September, 1907. 
The type is in the collection of the Boston Society of Natural 
History; the paratype is in the collection of the author. 
This small Tipula bears a remarkable resemblance to certain 
species of Nephrotoma, especially N. vittula Loew, which is likewise 
a northern form. The thoracic stripes in vittula are described as 
being black, but specimens in the collection of the Boston Society 
of Natural History have the stripes rich reddish chestnut and are 
very similar to the present fly; the broad yellowish white median 
thoracic stripe, the transverse caudal brown margins to the abdominal 
tergites and the venation will easily distinguish the forms. 
Tipula penobscot sp. n. 
Coloration gray and brown; antennae rather short, subunicolorous ; 
thorax light gray, the stripes quite indistinct, brown; wings sub- 
hyaline, the tip broadly dark brown; an indistinct brown band 
along the cord; wings with the tip of vein Ri atrophied or nearly so; 
male genitalia with the ninth tergite subquadrate, caudal margin 
deeply and broadly concave with a sharp median tooth; ninth 
pleurite small, complete. 
Male. — Length, 11 mm.; wing, 12.8 mm.; antennae about 3.3 mm. 
Frontal prolongation of the head rather long, yellowish brown;
