four times its diameter, the second a little longer, stouter, the third a little 

 longer than the second, more slender, the fourth y 2 longer than the third, 

 somewhat dilated. Mesonotum shining reddish brown. Scutellum, postscu- 

 tellum and abdomen mostly pale yellowish. Genitalia : a light fuscous yellow- 

 ish and thickly haired. Halteres, legs basally and the tarsal segments mostly 

 pale yellowish, the remainder dark straw. Claws moderately long, slender, 

 slightly curved, unidentate, the put villi a little shorter than the claws. Geni- 

 talia : basal clasp segment short, stout, the internal distal angle with a curved 

 chitinous spine having a length nearly equal to the diameter of the segment; 

 terminal clasp segment swollen, narrowly oval, thickly setose and with a series 

 of short, stout spines apically ; dorsal plate moderately long, broad, deeply and 

 triangularly emarginate, the lobes broadly rounded ; ventral plate moderately 

 long, broad triangularly emarginate, the lobes short and thickly setose. Harpes 

 strongly chitinized and tapering to a slightly recurved subacute apex. Type 

 Cecid. 1731. 



Asynapta borealis new species. 



This female was taken August 28, 191 7, by Mr. Howard Notman 

 at Keene Valley, N. Y. It is easily distinguished from related species 

 by the small number of subsessile antennal segments. 



Female. — Length 1.5 mm. Antennae nearly as long as the body, thickly 

 short-haired, light fuscous yellowish, 15 segments, the fifth with a stem about 

 J4 the length of the cylindrical basal enlargement, which latter has a length 

 twice its diameter. The palpi are over half the length of the antennas, the first 

 segment has a length about three times its diameter, the second is one half 

 longer than the first, somewhat stouter, the third is more than twice the length 

 of the second, strongly flattened and the fourth is about as long as the third 

 and more slender. Mesonotum reddish brown. Scutellum and postscutellum 

 reddish orange. Abdomen reddish brown, yellowish. Ovipositor about the 

 length of the abdomen. Halteres pale yellowish. Legs mostly dark straw, the 

 distal tarsal segments lighter. Claws moderately long, slender, evenly curved, 

 unidentate, the pulvilli as long as the claws. Terminal lobes of the ovipositor 

 narrowly oval and sparsely setose. Type Cecid. 1729. 



Asynapta dolens new species. 



The midge was taken by Mr. Howard Notman at Keene Valley, 

 N. Y., September 7, 1917. It runs in the key to A. jurcata Felt, from 

 which it may be easily separated by the only moderately inflated 

 terminal clasp segment, and its distinctly smaller size. 



Male. — Length 1.5 mm. Antennae z / 2 longer than the body, rather sparsely 

 haired, dark brown, the stems whitish, with at least 13 and probably with 16 

 segments, the fifth with a stem y 2 longer than the cylindrical basal enlarge-
