Crane-flies 15 c 
Locality: Holotype, d', Bernard harbour, Northwest Territories, July- 
August 1915 (F. Johansen). No. 826. 
This species is certainly close to T. hewitti, but I cannot make the two 
agree. Unfortunately each species is represented only by the unique male 
type and I do not care to remove the abdomen to submit the male genitalia to 
the critical study that some day may be necessary. More material from the 
Arctic north-west would probably decide the status of these two species which 
are closely allied but which certainly appear to be distinct. 
Tipula besselsoides, n. sp. 
General colouration grey; antennge rather short, black; body clothed with 
conspicuous erect hairs; femora light yellowish, tipped with black; ninth tergite 
of the male hypopygium with a small, U-shaped notch, the lateral lobes rounded. 
Male. — Length, 12 mm.; wing, 15-5 mm. 
Palpi black. Frontal prolongation of the head greyish black; nasus pro- 
minent. Antennae (PI. II, fig. 19) black; first segment of the scape long and 
slender, clothed with numerous outspreading hairs; flagellar segments very short, 
the basal swelling of the individual segments being al)out equal to the remainder 
of the segment. Head broad, eyes rather small, widely separated; vertical 
tubercle low; head dark grey with scattered setigerous punctures. 
Thorax dark grey, the prsescutum with three indistinct, darker grey stripes; 
thoracic interspaces with an abundant coarse, black hair. Halteres dull 
brownish yellow. Legs with the coxae grey clothed with numerous long pale 
hairs as in hesselsi O.S.; trochanters dark; femora light brownish yellow, the 
tips broadly black; tibiae light brown, the tips broadly black; tarsi dark brown. 
Wings nearly hyaline, the subcostal cell more yellowish; stigma brown, oval; 
apex of the wings a little darkened; veins dark brown; obliterative streak extend- 
ing from before the stigma into cell Mi] venation: crossvein m-cu not far beyond 
the fork of M. 
Abdomen dark grey, the segments conspicuously ringed with pale yellowish ; 
lobes of the hypopygium yellow. Male hypopj^gium with the ninth tergite 
(PI. Ill, fig. 39) rather extensive, the caudal margin somewhat rounded and 
with a deep, U-shaped, median notch; at the inner margin of the lateral lobes 
a small tubercle; entire sclerite black, clothed with numerous short, appressed 
hairs; suture between the tergite and sternite well-defined. Ninth pleurite 
small, incomplete, the suture indicated only beneath; outer pleural appendage^ 
(PL III, fig. 31) a small, suboval flattened lobe, pale brownish yellow, the outer 
face with abundant long pale hairs; inner pleural appendage (PI. Ill, fig. 42) 
elongate, chitinized, at the Imse a rounded knob clothed with long, delicate 
pale hairs, the outer margin with four stout bristles. Penis-guard a long, straight 
chitinized point, gradually narrowed from the base to the acute apex.

This species bears a strong superficial resemblance to T. besselsi Osten- 
Sacken in the grey colouration with conspicuous long, erect pile; the legs are 
differently coloured and the hypopygium of the male is very differently con- 
structed in the two species. It also resembles Stygeropis parrii (Kirby) super- 
ficially in colouration and the erect pile, but the verticillate antennae and nearly 
hyaline wings of the present species offer easy points for separation. 
Tipula subarctica, n. sp. 
Related to T. pribilofensis Alexander; general colouration dark; abdomen 
reddish brown with a dark median stripe on both the tergites and sternites; 
ninth tergite of the male hypopygium prominent with flattened, acute, lateral 
arms; eighth sternite produced caudad into a broad, flattened, shovel-like, 
median lobe.
