Palpi ; second segment with a length about three times its diameter, the third 

 a little longer than the second, more slender, the fourth irregular and appar- 

 ently twice the length of the third. Mesonotum shining dark brown. Scu- 

 tellum yellowish white, postscutellum yellowish orange. Abdomen dark yel- 

 lowish brown, the margins lighter ; genitalia darker. Halteres whitish trans- 

 parent, slightly fuscous apically. Coxae yellowish transparent, femora, tibiae 

 and basal tarsal segment dark straw, the distal half of the third, the fourth and 

 the fifth tarsal segments yellowish white. Genitalia ; basal clasp segment short, 

 very broad, terminal clasp segment short, greatly swollen, subglobose and with 

 a stout apical tooth ; dorsal plate long, deeply and triangularly emarginate, 

 the lobes roundly truncate ; ventral plate indistinct. Harpes slender, heavily

Colpodia porrecta new species. 



The midge was collected August 21, 1909, by Mr. C. P. Alex- 

 ander at Woodworth's Lake in the Adirondacks, altitude 1,570 feet. 

 It is easily distinguished from other females by the unusually long 

 stems of the flagellate antennal segments. 



Female. — Length 2.75 mm. Antennae nearly as long as the body, sparsely 

 haired, fuscous yellowish, 13 segments, the fifth with a stem as long as the 

 cylindric basal enlargement, which latter has a length about four times its 

 diameter ; terminal segment reduced, with a length three times its diameter, at 

 the distal third tapering to an acute apex. Palpi ; second segment with a length 

 about three times its diameter the third one-half longer, more slender, the 

 fourth one-half longer than the third. Mesonotum reddish brown, the sub- 

 median lines yellowish. Scutellum and postscutellum yellowish. Abdomen 

 brownish yellow. Halteres yellowish basally, fuscous apically. Coxae yellowish, 

 femora, tibiae, the first tarsal segment and the base of the second fuscous straw, 

 the remainder of the tarsi yellowish or yellowish white. Ovipositor short, the 

 lobes biarticulate, the terminal segment broadly oval and thickly setose. Type 

 Cecid. 1484. 



Colpodia sylvestris new species. 



The female described below was taken on a fern August 13, 1909, 

 by Mr. C. P. Alexander at Woodworth's Lake in the Adirondacks, 

 the altitude being 1,550 feet. This species is allied to C. temeritatis 

 Felt, though easily distinguished by its larger size and different 

 coloration. 



Female. — Length 3 mm. Antennae nearly as long as the body, sparsely 

 haired, the basal three segments yellowish white, the others light brown ; 

 twelve segments, the fifth with a stem three-fourths the length of the cylindric 

 basal enlargement, which latter has a length four times its diameter ; terminal 

 segment produced, with a length nearly six times its diameter. Palpi; first 

 segment irregular, second with a length four times its diameter, the third as
