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 stigma and along Cu; fourth band occupying the 

 wing-apex, darkest in the apices of cells R2 and Rz, 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 ; cross-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 fiat, 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 this 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.

Holotype. — cf, Ithaca, Tompkins Co., New York, June 12, 

 1915. 



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 fiy from all its relatives in Eastern North America. 

 Tipula kirbyana, new species.
