distal tarsal segments which are whitish. Genitalia ; basal clasp segment short, 

 stout; terminal clasp segment long, irregularly oval, the spur subapical ; dorsal 

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

 thickly setose ; ventral plate short, deeply and narowly emarginate, the lobes 

 slender, tapering, narrowly rounded. Harpes heavily chitinized, irregular and 

 reflexed. Type Cecid. 1492. 



Asynapta mediana new species. 



This species is described from a male taken August 24, 1909, by 

 Mr. C. P. Alexander in a quarry at Woodworth's Lake in the Adiron- 

 dacks, altitude 1,540 feet. It is allied to A. apicalis from which it 

 may be readily separated by the longer basal enlargement of the 

 antennal segments and the occurrence of the spur near the basal half 

 of the terminal clasp segment. 



Male. — Length 2.5 mm. Antennre one-fourth longer than the body, thickly 

 haired, light brown ; sixteen segments, the fifth with a stem two and one-half 

 times the length of the basal enlargement, which latter has a length twice its 

 diameter ; terminal segment produced, with a length about four times its 

 diameter and tapering to a slender, irregular apex. Palpi ; first segment with 

 a length about four times its diameter, the second as long as the first, stouter, 

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

 third, strongly compressed. Mesonotum reddish brown. Scutellum and post- 

 scutellum yellowish. Abdomen fuscous yellowish. Halteres yellowish basally, 

 fuscous apically. Cox^e and femora basally pale yellowish, basal portion of 

 femora, tibiae and tarsi dark straw, except the two distal tarsal segments, which 

 latter are yellowish white ; claws moderately stout, strongly curved, simple, the 

 pulvilli rudimentary. Genitalia ; basal clasp segment short, stout ; terminal clasp 

 segment long, stout, narrowly oval, the spur near the basal half; dorsal plate 

 long, deeply and broadly emarginate, the lobes obliquely truncate and sparsely 

 setose; ventral plate indistinct. Harpes short, stout, recurved; the ventral 

 margin finely dentate. Type Cecid. 1495. 



As3niapta umbra new species. 



The midge was collected by Mr. C. P. Alexander in Johnstown 

 Cemetery, August 6, 1909. It is related to A. flavida Felt from which 

 it may be easily separated by its darker color and particularly by the 

 shorter,-thicker antennal segments. 



Male. — T-ength 1.5 mm. Antenna; nearly as long as the body, sparsely 

 haired, dark brown ; seventeen segments, the fifth with a stem one-half the 

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

 fourth greater than its diameter and bears a very thick whorl of long, slender 

 hairs ; terminal segment produced, with a length nearly three times its diameter 

 and tapering slightly to a narrowly rounded apex. Palpi ; first segment 

 irregular, second broad, with a length three times its diameter, the third a
