little longer and more slender than the second, the fourth as long as the third, 

 more slender. Mesonotum shining, very dark brown. Scutellum, and post- 

 scutellum dark yellowish brown. Abdomen sparsely haired, fuscous yellowish, 

 the genitalia darker. Halteres whitish transparent. Coxse and legs a some- 

 what variable whitish yellow ; claws stout, evenly curved, unidentate, the 

 pulvilli as long as the claws. Genitalia ; basal clasp segment short, stout ; 

 terminal clasp segment very short, greatly swollen, irregularly oval ; dorsal 

 plate long, deeply and triangularly emarginate, the lobes broadly rounded ; 

 ventral plate shorter, triangularly emarginate, the lobes obliquely truncate. 

 Harpes slender, chitinized, recurved. Type Cecid. 1499. 



Porricondyla setosa new species. 



This midge was taken August 21, 1909, by Mr. C. P. Alexander 

 in a bog swamp at Woodworth's Lake in the Adirondacks, altitude 

 1,570 feet. It is related to P. caudata Felt from which it is readily 

 separated by color characters and especially by the shape of the 

 terminal lobe of the ovipositor. 



Female. — Length 1.75 mm. Antennae nearly as long as the body, thickly 

 haired, light brown ; thirteen segments, the fifth with a stem one-fourth the 

 length of the cylindric basal enlargement, which latter has a length about four 

 times its diameter ; terminal segment reduced, slender, fusiform, with a length 

 about three times its diameter. Palpi ; first segment with a length four times 

 its diameter, the second a little stouter, the third a little longer and more 

 slender than the second, the fourth one-half longer and more slender than the 

 third. Mesonotum shining brownish black. Scutellum and postscutellum fus- 

 cous yellowish. Abdomen rather thickly haired, dark brown. Halteres yellow- 

 ish basally, fuscous apically. Coxas yellowish, femora, tibiae and tarsi fuscous 

 straw, the fourth and the basal portion of the fifth tarsal segments white. 

 Ovipositor short, the terminal lobes lanceolate and thickly setose. Type Cecid.

Janetiella parma new species. 



This yellowish midge was taken by Mr. C. P. Alexander. August 

 21, 1909, in a bog swamp at Woodworth's Lake in the Adirondacks, 

 altitude 1,570 ft. It is easily separated from allied forms by the 

 greatly produced antennal segments. 



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

 light brown, presumably sixteen segments ; the fifth with a stem twice the 

 length of the cylindric basal enlargement, which latter has a length three- 

 fourths greater than its diameter. Palpi ; first segment irregular, with a length 

 three times its diameter, the second as long as the first, stouter, the third one- 

 half longer than the second, slender, the fourth one-half longer than the third. 

 Mesonotum reddish brown, the submedian lines yellowish orange. Scutellum, 

 postscutellum and basal abdominal segments yellowish or yellowish orange,
