lateral margins of the tergites broadly yellov/ish. Sternites 
reddish brown with an indistinct, narrow, brown median line; 
lateral portions of the sternites infuscated, caudal margins of the 
segments yellowish. Male hypopygium with the ninth tergite 
rather prominent, the caudal margin with a broad and deep, 
U-shaped median notch; the basal portion of the tergite is tumid, 
shiny chestnut but a broad margin around the notch is flattened, 
the extreme edge narrowly blackened, chitinized, lateral lobes 
truncated. Ninth pleurite complete, semicircular; outer pleural 
appendage elongate-cylindrical, clothed with long, golden hairs; 
inner pleural appendage very long and narrow, jutting into the 
notch of the tergite, the outer edge clothed with long, pale hairs 
that project backward to produce a hystriciform appearance; 
apex of the appendage shiny chestnut-brown. From the ventral 
caudal angle of the pleurite arises a shiny, chestnut-brown, flat- 
tened lobe that is directed caudad, its apex truncated. Ninth 
sternite with a deep, V-shaped median notch that extends a little 
more than half the distance to the margin of the eighth sternite. 
Eighth sternjte unarmed. 
Habitat. — Alaska. 
Holotype.—d', Point Barrow, Alaska, July 14, 1898. 
This species is closely allied to Tipula whi-tneyi Alex, from the 
Pribilof Islands, Alaska, but is readily separated by the full- 
winged males and the details of the hypopygium. 
NOTE ON OVI POSITION OF GASTEROPHILUS NASALIS L. 
BY CHARLES H. T. TOWNSEND, WASHINGTON, D.C. 
In the November, 1892, issue of Entomological News, pages 
227-8, I published some notes on this subject, in which I stated 
that "I noticed the fly alight several times, always exactly in the re- 
gion ventrad of the first cervical vertebrae " This observation relates 
to a female which I captured May 15, 1892, while it was flying at 
the throat of my horse, near Las Cruces, New Mexico. In the 
same notes I quoted Brauer's statement (Mon. Oestr., page 60) 
that "according to Dr. Green G. nasalis deposits its white eggs in 
the region of the throat of the horse." I further stated that I had 
not found the eggs of the fly, though I searched the ventral region 
of the throat after capturing the above female.
