16 c Canadian Arctic Expedition, 1913-18 
Male. — Length, 12-5 mm.; wing, 14 mm. 
Head discoloured. Antennse broken. 
Pronotal scutum dark, the scuteUum dull yellowish. Mesonotal prsescutum 
dark coloured, almost black in the type, but badly discoloured, the thoracic 
stripes, if present normally, being obliterated; normal specimens are almost 
certain to be very dark grey. Pleura blackish, grey pruinose; dorso-pleural 
membranes dull yellow. Halteres brown, the knobs darker. Legs with the 
coxae black, grey pruinose; trochanters brown; femora reddish brown, the tips 
narrowly and indistinctly darkened; tibise brown, the apices blackened; tarsi 
dark brown. Wings nearly hyaline, the costal and subcostal cells concolourous 
with the rest of the wing; veins brown; wings in the vicinit}^ of the stigmal 
region injured; venation: Ri persistent for its entire length; the m-cu crossvein 
inserted just beyond the fork of M. The fly is full-winged. 
Abdominal tergites reddish brown with a broad, black, median stripe; 
ninth tergite black; sternites dull brown with an interrupted blackish median 
stripe. Male hypopygium with the ninth tergite (PI. Ill, fig. 41) very large 
and prominent, black, chitinized, the caudal margin with an acute, V-shaped, 
median notch, finely denticulate, the lateral angles produced far caudad into 
flattened ears. Ninth pleurite incomplete, the suture indicated beneath, an 
acute dorso-caudal arm of the pleurite runs beneath the tergal lobes. Eighth 
sternite with a broad, shovel-shaped, median lobe extending caudad and dorsad, 
its caudal margin evenly and gently notched and provided with short, delicate 
hairs. Eighth tergite completely concealed beneath the seventh tergite. 
Locality: Holotype, cf, west of Kongenevik, Camden bay, Alaska, Julv 4, 
1914 (F. Johansen). No. 442. 
This interesting new species is related to T. prihilofensis Alexander from 
the Pribilof islands off the western coast of Alaska. It is an entirely distinct 
species, being full-winged and the male hypopygium quite differently constructed 
although both species have the curious spoon-like elongation of the eighth sternite. 
I have seen another species of the same group from Kamchatka, eastern Siberia 
Tipula kanichatkensis Alexander. 
Very recently I have received from Prof. Hine another specimen in much 
better condition. This specimen may be considered as paratypical and the 
following additional" characters should be noted: 
Male: — Length, 14 mm.; wing, 13 mm. 
Frontal prolongation of the head dark purplish brown above, more yellow 
laterally. Antennae rather long, the scape a very little paler than the dark 
brownish black flagellum; flagellar segments rather deeply incised beneath. 
Head light grey, a small brownish blotch on the disk of the vertex. Eyes small; 
genae prominent. 
Mesonotal stripes very indistinct, brown, ground-colour of the mesonotum, 
light grey. Pleura light grey, the dorso-pleural membranes light yellow. 
Paratype, cf, Katmai, Alaska, July, 1917 (J. S. Hine). 
Specimen in the collection of Prof. Hine.

At the present time this genus of flies offers almost insuperable taxonomic 
difficulties. Some twenty-five or thirty species have been proposed, but that 
very many of these are synonyms of others is unquestioned. It seems now that 
the only hope of straightening this apparently hopeless tangle is for some
