The species is closest to T. submaciilata Loew., but in the 

 heavy wing pattern bears a superficial resemblance to the angulata 

 and suhfasciata groups, from both of which the structure of the 

 hypopygium will readily distinguish it. The thoracic pattern of 

 suhmacidata is quite different, the median stripe being dissected 

 by a very broad, pale line. 

 Tipula fultonensis, sp. n. 



Arctica group; related to T. longiventris Loew., but the abdo- 

 men of the female is about half an inch shorter than in the same 

 sex of that species (abdomen, fultonensis, 16 mm.; longiventris 

 26-27 mm.). 



Female. — Length 22 mm.; wing 18.5 mm.; abdomen 16 mm. 



Antennae with the apical flagellar segments indistinctly bi- 

 colorous. Head dull gray, the vertex with a narrow, brown line. 



Praescutum buffy with three broad, grayish brown stripes 

 that are broadly margined with dark brown; thoracic interspaces 

 without brown setigerous punctures; each lobe of the scutum with 

 a small, anterior gray spot and a larger brownish area behind; 

 postnotum gray with a narrow, brown median line. Pleura whitish 

 gray pruinose. Legs with the coxae grayish; femora dull yellow, 

 the tips very pale brown; tibiae similar; tarsi brown. Wings with 

 a brownish, gray pattern. 



Abdominal tergites dull brownish yellow, broadly trivittate 

 with dark brown, the lateral margins of the abdominal segments 

 dark brown basally, gray apically, the brown sublateral stripe 

 being very sensitive on the basal portion of each segment, sternites 

 grayish brown; valves of the ovipositor and the dorsal shield 

 chestnut brown, the lateral margins of the valves with about ten 

 acute teeth; extreme tips not divergent. 



Habitat. — ^Northeastern United States. 



Holotype.— 9, Mt. Buell,Sacandaga Park, Fulton Co., N.Y., 

 altitude 1,500 ft., June 15, 1916, (C. P. Alexander). 



Type in the collection of the author. 



Compared with females of longiventris, the present species 

 offers the following differences: thoracic dorsum buffy brown, 

 rather than gray; wing pattern more brown, heavier; abdomen 

 short; ovipositor and dorsal shield chestnut brown instead of 

 almost black, and the tips are scarcely elongate and slightly 

 divergent.
