1912] Alexander — New Nearctic Tipululae (Diptera) 167 



Limnophila larlcicola sp. nov. 



Small; antennae of the cf elongate; color of the body light yellow; wings sub- 

 hyaline. 



cf. Length, uncertain, abdomen broken; wing, 5.4 mm. 



Head: antennae elongate, the segments indistinct, twisted, elongate-ovate, nar- 

 rowed at the ends, brownish in color; front, vertex and occiput light brown, but 

 discolored, and possibly different in fresh material. 



Thorax: pronotum brown; mesonotum, praescutum brown on the anterior mar- 

 gin; a dark brown spot on the frontal third of the sclerite in a median position; 

 remainder of the sclerite light yellow, sub-shining, with a sparse pale bloom; scu- 

 tum and post-notum light yellow, the latter with an indistinct narrow brown median 

 stripe; pleurae yellow, darker near the dorsal margin. Halteres, stem pale, knob 

 darker. Legs: coxae and trochanters light yellow; remainder of the legs brown, 

 rather darker outwards. 



Wings: subhyaline, stigma indistinct, brown. Venation (See fig. 4): Sc rather 

 long, extending to beyond the fork of Rs; cross- vein r at the tip of Ri; Rs short, 

 less than Mi or M2 in length; R2+3 rather long, as long as Rs, gently arcuated; R2 

 rather oblique, cross-vein r near its middle; deflection of JIa+s about as long as cross- 

 vein r-m; petiole of cell Mi moderately long, about three-fifths of cell Mi; basal 

 deflection of Cui beyond the middle of cell 1st M2. Cell R2 very acute at its proxi- 

 mal angle; cell 1st M2 long and narrow. 



Abdomen broken. 



Holotype, cT. Canada Lake, Fulton Co., N. Y.; June 20, 1911 (Alexander). 

 Occurred in an extensive sphagnum bog, on vegetation growing underneath larch 

 trees, (altitude 1550 feet) 



Type in author's collection. 



This species by its elongate antennae in thecf , is allied to poetica 

 O. S. I thought that it was a small cf of this species until I saw 

 the types in Cambridge. Poetica is conspicuously larger, with 

 quite different antennal structure. In laricicola, the antennal 

 segments are twisted, and the sutures between them indistinct, 

 producing an appearance quite different from that which obtains 

 in the male sex of poetica, tenuipes, niveitarsis, etc. Venationally, 

 this new species differs from poetica in its longer R2+3> shorter 

 petiole to cell Mi, etc. Unfortunately my type, and only speci- 

 men, was recently accidentally damaged. 



Eriocera albihirta sp. nov. 

 Antennae short in the cf ; cell Mi present; body densely clothed with long white 

 hairs. 



cf Length, 15 mm.; wing, 15.6 mm.; antenna, 4.5 mm. 

 Fore leg, fem. 8 mm.; tibia, 10 mm. 

 Middle leg, fem. 9.2 mm.; tibia, 8.4 mm. 

 Hind leg, fem. 12 mm.; tibia 12.6 mm.
