the third a little shorter than the second, the fourth one-half longer than the 

 third. Mesonotum reddish brown. Scutellum and postscutellum yellowish 

 brown. Abdomen thickly haired, dark yellowish brown. Halteres and coxae 

 pale yellowish, femora basally, the distal portion of femora, tibise and tarsi dark 

 straw ; claws strongly curved, the anterior unidentate, the pulvilli rudimentary. 

 Genitalia ; basal clasp segment stout, the terminal clasp segment long, swollen 

 subapically ; dorsal plate broad, very broadly and roundly emarginate ; ventral 

 plate long, slender, narrowly rounded. Type Cecid. 1497. 



Bremia tristis new species. 



This species is described from a male taken by Mr. C. P. Alex- 

 ander, August 10, 1909, in a stone quarry at Woodworth's Lake in 

 the Adirondacks, altitude 1,500 feet. It is allied to B. podophyllce 

 Felt from which it is most readily separated by the broadly and 

 roundly emarginate dorsal plate. 



Male. — Length 1.2 mm. Antennae twice the length of the body, sparsely 

 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 greatly produced, the basal portion of the stem with a length seven 

 times its diameter, the distal enlargement irregular, narrowly pyriform and 

 apically with a fingerlike process having a length six times its diameter. Palpi ; 

 first segment subquadrate, the second with a length three times its diameter, 

 the third one-half longer, more slender, the fourth one-half longer than the 

 third, more slender. Mesonotum reddish brown, the submedian lines, scutellum 

 and postscutellum yellowish. Abdomen thickly haired, yellowish brown, darker 

 apically. Genitalia yellowish. Halteres fuscous yellowish, fuscous apically. 

 Coxae and femora basally yellowish white, the distal portion of femora light 

 brown ; tibiae and tarsi mostly dark brown ; claws moderately stout, strongly 

 curved, the anterior unidentate, pulvilli rudimentary. Genitalia ; basal clasp 

 segment stout; terminal clasp segment long, tapering uniformly; dorsal plate 

 short, broad, very broadly and roundly emarginate, the lateral margins obliquely 

 truncate; ventral plate indistinct. Type Cecid. 1475. 



Bremia montana new species. 



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

 Impatiens at Mountain Lake in the Adirondacks, altitude 1,590 feet. 

 It is easily distinguished from other species of Bremia having the 

 stems of the fifth antennal segment unequal, by the length of the basal 

 portion. 



Male. — Length 1.5 mm. Antennae probably one-half longer than the body, 

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

 a length two and one-half and three and one-half times their diameters, re- 

 spectively. Palpi ; the first segment quadrate, with a length about twice its 

 diameter, the second a little longer, stouter, the third a little longer than the
