June, :9i4.] FeLT : DESCRIPTIONS OF GaLL MiDGES. 125 



coxffi pale yellowish, the legs light straw, except the somewhat lighter midtarsi 

 and the nearly white posterior tarsi ; claws slender, evenly curved, simple, the 

 pulvilli shorter than the claws. Genitalia ; basal clasp segment short, stout ; 

 terminal clasp segment short, the basal three-fourths greatly swollen, subglo- 

 bose, the distal fourth produced as a relatively slender spur ; dorsal plate long, 

 broad, deeply and triangularly emarginate, the lobes broadly rounded and 

 thickly setose ; ventral plate long, broad, deeply and triangularly emarginate, 

 the lobes narrowly rounded, setose. Harpes slender, heavily chitinized, simple, 

 the distal fourth curved at nearly a right angle. Type Cecid. 1478. 



Colpodia capitata new species. 



The peculiar male was taken August 19, 1909, by Mr. C. P. Alex- 

 ander at Woodworth's Lake in the Adirondacks, altitude 1,550 feet. 

 This species is allied to C. carolincv Felt, though easily separated by 

 the longer basal enlargement of the flagellate antennal segments and 

 the peculiar genitalia. 



Male. — Length i mm. Antennae probably twice the length of the body, 

 sparsely haired, light brown, presumably sixteen segments ; the fifth with a 

 stem two and one-half times the length of the basal enlargement, which latter 

 has a length two and one-fourth times its diameter. Palpi ; first segment with a 

 length about five times its diameter, the second as long as the first, stouter, 

 the third a little longer than the second, more slender, the fourth one-fourth 

 longer than the third. Mesonotum reddish brown. Scutellum and postscu- 

 tellum yellowish. Abdomen light brownish yellow. Legs a nearly uniform 

 light straw. Genitalia ; basal clasp segment short, stout ; terminal clasp seg- 

 ment short, greatly dilated and irregularly and obliquely truncate apically ; 

 dorsal plate broad, deeply and triangularly emarginate, the lobes broadly 

 rounded and thickly setose ; ventral plate long, broad, broadly and roundly 

 emarginate, the lobes narrowly rounded. Harpes heavily chitinized, slender, 

 irregularly furcate apically. A median organ, probably style, slender, heavily 

 chitinized and apically apparently with a pair of heavy, curved clasping spurs. 

 Type Cecid. 1480. 



Colpodia ovata new species. 



The male was taken by Mr. C. P. Alexander August 24, 1909, in 

 a quarry at Woodsworth's Lake in the Adirondacks, altitude 1,540 

 feet. It is related to C. diervillcc Felt from which it is readily sep- 

 arated by color characters and the length of the basal enlargement of 

 the flagellate antennal segments. 



Male. — Length 1.75 mm. Antennae nearly twice the length of the body, 

 rather thickly haired, light brown ; sixteen segments, the fifth with a stem 

 nearly two and one-half times the length of the cylindric basal enlargement, 

 which latter has a length twice its diameter; terminal segment reduced, with a 

 length three times its diameter and tapering gradually to an obtuse apex.
