black spot commencing anterior to the base of the wing and reach- 

 ing with a slight interruption to the middle coxa. Abdomen red- 

 dish brown distally, covered with pitchy black scales, the latter less 

 dense on the venter. Ovipositor reddish yellow, becoming pale 

 yellow, almost white at the tip. Wings dusky, costa black, the third 

 vein uniting with costa at the distal third ; halteres yellowish with the 

 capitate portion and upper part of the stem covered with pitchy black 

 scales. Coxae and femora yellowish, the distal half of the femora 

 covered with black scales, becoming more dense toward the apex; 

 tibiae and tarsi black; claws long, stout, strongly curved. Ovipositor 

 probably nearly as long as the body; terminal lobes long, slender, 

 broadly rounded. 



Male. About as the female, more slender and not so black, but 

 smoky or brown-black with a pitchy reflection. Antennae with 

 1 6 to 1 8 segments. Palpi; short, inconspicuous, apparently com- 

 posed of two segments, the first irregularly oval, deeply divided 

 near the middle, the second consisting of a transverse oval basal 

 portion and a long, slender, tapering distal part, the latter with 

 a length fully five times its diameter. Wing (pi. 6, fig. i) with 

 thick, black scales on the costa not extending beyond the point 

 where the third vein unites with the border. Genitalia (pi. 8, 

 fig. i); basal clasp segment long, stout, obliquely truncate; terminal 

 clasp segment short, greatly swollen basally; dorsal plate short, 

 broad, deeply and triangularly incised; ventral plate broad, broadly 

 rounded. Harpes broad at base, dentate. 



Described from specimens received from the Ohio Agricultural 

 Experiment Station December 1906, presumably reared by Marten.

Several midges were reared in early May 1908 from a small, 

 brownish, blister gall on a somewhat hairy unknown species of aster 

 found at Karner near the Waldorf station in early April. 



Gall. The gall is about 3 mm in diameter, circular, brownish 

 and with a more or less distinct yellowish ring. 



Male. Length 2 mm. Antennae yellowish brown; 16 segments, 

 the fifth with a length about three-fourths its diameter; terminal 

 segment produced, compound. Palpi; the first segment subquad- 

 rate, the second longer, broadly oval. Mesonotum dark brown, 

 the submedian lines sparsely haired. Scutellum dark brown, post- 

 scutellum fuscous yellowish. Abdomen dark brown, the segments 

 narrowly margined posteriorly, the latter interrupted mesially; the 

 sixth and seventh segments mostly orange. Wings hyaline, costa 

 dark brown, the third vein uniting with costa at the basal half, the 

 discal spot large; halteres a variable yellowish. Coxae and basal 

 portion of femora yellowish, the distal part of femora, tibiae and
