the distal abdominal segments rather thickly haired, yellowish brown, the 

 genitalia nearly fuscous. Halteres whitish basally, fuscous apically. Coxae and 

 the base of femora yellowish, the distal portion of femora, tibiae and tarsi dark 

 straw ; claws slender, strongly curved, simple, the pulvilli half as long as the 

 claws. Genitalia, basal clasp segment long, slender; terminal clasp segment 

 long, slender, tapering; dorsal plate shell-like, broad, broadly and roundly 

 emarginate, the emargination thickly setose ; style long, slender, narrowly 

 rounded apically; other structures obscure. Type Cecid 1488. 



Toxomyia americana new species. 



This species is described from a small midge collected collected by 

 Mr. C. P. Alexander, Atigtist 21, 1909, in a bog swamp at Wood- 

 worth's Lake in the Adirondacks, altitude 1,570 feet. It is easily 

 separated from the two known West Indian species recorded as living 

 upon fungi, by the longer basal portion of the stem of the fifth 

 antennal segment of the male and its darker color. 



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

 thickly haired, light brown ; fourteen segments, the fifth having the stems with 

 a length three and four and a half times their diameters, respectively; terminal 

 segment produced, the basal portion of the stem with a length fully six times 

 its diameter, the distal enlargement produced, irregular and with a long, stout, 

 tapering process apically. Palpi ; first segment short, irregular, the second with 

 a length four times its diameter, the third a little longer than the second, more 

 slender, the fourth one-fourth longer than the third, dilated. Mesonotum a 

 variable reddish brown. Scutellum and postscutellum yellowish. Abdomen 

 thickly haired, fuscous yellowish. Halteres, coxae and femora mostly fuscous 

 yellowish, the tibiae and anterior and mid tarsi fuscous straw, the posterior 

 tarsi lighter. Claws slender, strongly curved, the anterior unidentate, the pul- 

 villi about half the length of the claws. Genitalia ; basal clasp segment stout, 

 with a longitudinal setose ridge near the middle ; terminal clasp segment mod- 

 erately long, stout ; dorsal plate narrowly and uniformly emarginate, the lobes 

 narrowly rounded, setose; ventral plate indistinct. Type Cecid. 1485. 



Bremia borealis new species. 



The midge was taken by i\Ir. C. P. Alexander, August 24, 1909, 

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

 feet. It is easily distinguished from other species referable to this 

 genus by the longer distal enlargement of the fifth antennal segment 

 and the distinct subapical swelling of the terminal clasp segment. 



Male. — Length 1.3 mm. Antennae twice the length of the body, thickly 

 haired, light brown ; fourteen segments, the fifth with the stems one and one- 

 half and three and one-half times their diameters, respectively, the distal en- 

 largement with a length one-half greater than its diameter. Palpi; first seg- 

 ment subquadratc, the second irregular, with a length five times its diameter,
