 comparatively narrow, directed dorsad, the tip bent cephalad into the 

 notch of the tergite; at its base, this appendage is expanded into a 

 flattened portion that is directed laterad. Ninth stemite with a broad

Habitat. — Alaska. 



Holotype, cf, Katmai, July, 1917 (Jas. S. Hine). 



This interesting little Tipula is very closely allied to T. 

 cineracea Coquillett in its general size and habitus, the conspic- 

 uous lack of a nasus and the venational characters, especially 

 the very high cell 1st M2. It differs from cineracea in the 

 shorter antennae, with the first flagellar segment entirely dark; 

 the dark brownish gray coloration of the body, the more sat- 

 urated wings and the details of the male hypopygium; in 

 ■cineracea, the outer pleural appendage is much broader, sub- 

 spatulate and conspicuously light yellow in color; the notch 

 •of the ninth sternite is small, V-shaped and that portion of the 

 sclerite cephalad of it is feebly carinate.
