basal in position occupying the cubital and anal cells; the second 
band about mid-length of the basal cells, darkest in cells R and M, 
in the anal cells paler but more diffused ; the third band at the cord, 
darkest near the stigm.a and along Cu; fourth band occupying the 
wing-apex, darkest in the apices of cells R2 and Rs, caudad of 
these paler; base of the wing, costal and subcostal cells indistinctly 
tinged with yellow; veins dark brown. Venation: vein R2 per- 
sistent for its entire length; petiole of cell Mi. shorter than this 
cell; cress-vein m-cu present, situated at about the basal third or 
quarter of cell 1st M2. 
Abdominal tergites yellow with a very broad, dark brownish 
black dorsal stripe beginning on segment two, continuing to seg- 
ment seven; this occupies most of the dorsum of all these seg- 
ments being interrupted caudally by a broad, yellowish ring; 
lateral margins of the tergites very broadly silvery, caudal margins 
very narrowly of the same colour; a narrow, interrupted, dark 
brownish black line just inside the gray margins; segments eight 
and nine brown. Sternites light yellowish brown with an indis- 
tinct, pale brownish line, the apical sternites light brown. Male 
hypopygium enlarged; ninth tergite very large and prominent, 
subquadrate, the dorsum almost flat, not chitinized; caudal margin 
with a \ery deep, narrow, median split, the adjacent lobes very 
broad, their apices almost truncated, very narrowly chitinized. 
Ninth pleurite small, complete. Ninth sternite deeply and broadly 
split, the margins fringed with abundant long, pale hairs that are 
decussate across thus median notch. Eighth sternite almost 
straight or with a very broad, V-shaped notch, on either side with 
a large tuft of yellow hairs that are decussate across the median 
line.

This beautiful Tipula is very different from any species that 
I have ever seen, in some ways suggesting Tipula ternaria Loew 
of Northeastern North America but in reality a very different 
species. The yellow subterminal annulus on the femora will 
separate the fly from all its relatives in Eastern North America. 
Tipula kirbyana, new species.
