Crane-flies 11 c 
dorsad. Eighth sternite with the caudal margin broadly concave, the lateral 
angles bearing small tufts of hairs. 
The female is similar but of a less heavy build; the al)dominal tergites 
have the same orange-yellow stripes on either side of the broad median area, 
these most conspicuous on segments three to five where they appear as bright 
triangles.

This interesting Arctic Neyhrotoma belongs to the same group as the 
Palsearctic N . pratensis (Linnaeus) and N. nox (Riedel) and the N . penumbra 
Alexander from the high mountains of Northeastern North America. I have 
seen specimens of a species of this same group from Greenland that are close 
to pratensis but seem to represent a new species. 
Genus Tipula Linnaeus. 
Tipula Linnaeus; Systema Naturae, edition 10, p. 585; 1758. 
The present collection included seven species of this genus, the only des- 
cribed one being the common and apparently widely distributed Tipula arctica 
Curtis. I expected that T. pratorum Kirby^ would be found amongst the 
material but such was not the case, there being no species having the antennal 
scape yellow. The only species in this collection with any yellow on the antennae 
is T. diflava which does not agree at all with Kirby's rather unsatisfactory 
description. 
Tipula johanseni, n. sp. 
Antennae black; head grey, along the inner margin of the eye broadly paler; 
thoracic dorsum with four dark brown stripes; wings with the tip of vein 
R2 pale, subatrophied ; crossvein m obliterated by atrophy. 
Male. — Length, 11-8 mm.; wing, 12-4 mm. 
Palpi black. Frontal prolongation of the head dark grey, the nasus short, 
blunt. Antennae (PI. II, fig. 15) black; first segment of the scape relatively 
short, not as long as the first flagellar segment; flagellar segments rather elon- 
gated, the basal swelling oval, shorter than the remainder of the segment. 
Head dull grey, paler along the inner margin of the eye; sides of the vertex 
with scattered long, coarse bristles. 
Thoracic dorsum dull grey with four dark brown stripes, the median pair 
narrow, separated from one another by a broad stripe of the ground colour. 
Pleura dark grey, the dorso-pleural membranes dull yellowish. Halteres rather 
long, brown, the knobs still darker brown. Legs with the coxae dull grey and 
provided with long pale hairs; trochanters black; remainder of the legs broken. 
Wings light grey, the costal and subcostal cells a little more yellowish; stigma 
brown; an indistinct dark cloud at the tip of Rs; veins dark brown; venation 
(PI. I, fig. 11) tip of vein Ro pale, subatrophied; crossvein m obliterated or 
nearly so. 
Abdominal segments blackish, the caudal and lateral margins bi'oadly 
paler; hypopygium yellow. Male hypopygium with the ninth tergite (PI. Ill, 
fig. 32) not prominent, the sides oblique, the caudal margin very deeply split 
by a V-shaped median notch that extends almost to the eighth tergite, the 
lobes thus formed long, subacute. Ninth pleurite extensive, subtriangular, 
the caudal angle extended out into a short blunt point; outer pleural appendage 
not prominent, cylindrical to slightly flattened, with long golden hairs; inner 
pleural appendage greatly compressed. Ninth sternite profoundly incised be-
