gular lobe with a small lobule on the ventral outer edge, this 
appendage pale and covered with a dense, pale pubescence; the 
inner appendage is also pale and fleshy, arising from the apex of the 
pleural region just inside the outer pleural appendage; this appendage 
is darker colored, thicker, reddish yellow; from the notch between 
the pleurite and the sternite arises a flattened, chitinized appendage. 
Ninth sternite divided to the very base by a split which widens out 
behind. Eighth sternite unarmed. 
Hahiiat. — Arctic America. 
Holotype, cf , Fort Resolution, Hudsons Bay Territory, Canada 
(Kennicott) . 
The type is in the collection of the Museum of Comparative 
Zoology where it bore the manuscript name of tetra in Loew's writing. 
This species is dedicated to the intrepid Arctic explorer and collector, 
Robert Kennicott. 
This species can be confused only with the more southern per- 
longipes Johnson, from which it may be separated by the following 
key: 
1. Antennae bicolorous; thorax pale yellow \vith three brown stripes, 
the lateral pair less distinct than the median one; legs long 
(male, fore leg, femur, 10 mm.; tibia, 11.8 mm.; middle leg, 
femur, 11.3 mm.; tibia, 11.5 mm.); male hypopygium with the 
mecHan lobe of the ninth tergite entire or the bifid nature barely 
incUcated ; outer pleural appendage long and narrow, narrowed 
at both ends; ninth sternite extensive, deeply incised, the 
margins of the incision closely appressed forming a carinate 
ridge (Eastern United States) perlongipes Johnson.^ 
Antennse unicolorous or nearly so; thorax gray with a single 
delicate brown line; legs short (male, fore leg, femur 7.3 mm.; 
tibia, 9 mm.; middle leg, femur, 8.5 mm.; tibia, 8.8 mm.); 
male hypopygium with the median lobe of the ninth tergite 
UM; outer pleural appendage broad, subrectangular; ninth 
sternite deeply incised, the margins merely approximated, 
not carinate (Arctic America) kennicotti sp. n. 
Tipula piliceps sp- n. 
Coloration blue-gray with brown markings; body with abundant 
pale hair. 
Female. — Length, 14.5 mm.; wing, 16 mm. 
Frontal prolongation of the head dark bluish brown, the nasus 
distinct. Palpi short, brownish black. Antennae dark brownish 
black. Head bluish gray with a broad brown median stripe.
