ment, which latter has a length y 2 greater than its diameter and bears a mod- 

 erately thick whorl of long, stout setae. Palpi: first segment with a length 

 about three times its diameter, the second y 2 longer, more slender, the third as 

 long as the second, the fourth y 2 longer than the third. Mesonotum dark red- 

 dish brown. Scutellum yellowish white. Postscutellum yellowish. Abdomen 

 rather thickly haired, mostly fuscous yellowish, the basal segments and geni- 

 talia somewhat fuscous. Halteres whitish transparent. Coxae and femora 

 basally yellowish, the remainder of the legs mostly pale straw. Claws mod- 

 erately long, stout, curved, unidentate, the puvilli nearly as long as the claws. 

 Genitalia: basal clasp segment moderately long, stout, terminal clasp segment 

 short, stout ; dorsal plate moderately long, deeply and narrowly incised, the 

 lobes narrowly rounded ; ventral plate long, broad and broadly rounded. Type 

 Cecid. 1748. 



Camptomyia antennata new species. 



This midge was taken September 15, 1917, by Mr. Howard Not- 

 man at Keene Valley, N. Y. It is related to C. montana Felt, from 

 which it is easily separated by the larger number of antennal seg- 

 ments and the more produced stems. 



Male. — Length 1.5 mm. Antennas more than twice the length of the body, 

 sparsely haired, yellowish brown, probably with 22 segments, the fifth with a 

 stem y 2 longer than the subcylindrical basal enlargement, which latter has a 

 length y 2 greater than its diameter. Palpi : first segment with a length about 

 three times its diameter, the second segment a little longer than the first, the 

 third about twice the length of the second and the fourth a little longer than 

 the third, the latter two more slender than the basal two. Mesonotum dark 

 brown. Scutellum pale yellowish. Postscutellum yellowish brown. Abdomen 

 mostly dark yellowish brown. Halteres yellowish transparent. Legs mostly 

 dark straw, the tarsi a little darker. Claws moderately stout, strongly curved, 

 unidentate, the pulvilli a little longer than the claws. Genitalia : basal clasp 

 segment moderately long, stout ; terminal clasp segment short, stout and nar- 

 rowly rounded and thickly pectinate apically ; dorsal plate long, divided, the 

 lobes broad, obliquely truncate ; ventral plate long, deeply and narrowly in- 

 cised, the lobes broad and tapering to a narrowly rounded and sparsely setose 

 apex. Style rather short, irregular and narrowly rounded apically. Type 

 Cecid. 1728. 



Camptomyia dentata new species. 



This midge was taken September 3, 1917, by Mr. Howard Notman 

 at Keene Valley, N. Y. It is related to C. montana Felt, from which 

 it is easily separated by the shorter stems of the flagellate antennal 

 segments and by the markedly different terminal clasp segment.
