Locality: Holotype, cf, 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 1 1n- 

 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; antennae rather short, black; body clothed with 

 conspicuous erect hairs; femora light yellowish, tipped with black; ninth termite 

 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 (PL 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 about 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 praescutum 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 besselsi 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 M 4 ; 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 hypopygium with the ninth tergite 

 (PL III, 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 (PL III, fig. 42) 

 elongate, chitinized, at the base 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. 



Locality: Holotype, cf, Bernard harbour, Northwest Territories, July 1-14, 

 1916 (F. Johansen). No. 422. Paratopotype, d". No. 417. 



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.
