1908 Felt, E. P. N. Y. State Mus. Bui. 124, p. 416

 1907. Midges have been reared recently by Dr J. M. Aldrich from 

 an almost pure blue grass sod. 

 \ 



Female. Length 1.5 mm. Antennae nearly as long as the bod}^ 

 sparsely haired, brown; 13 segments, the fifth with a stem one- 

 fourth the length of the cylindric basal enlargement, which latter 

 has a length six times its diameter; terminal segment slightly pro- 

 duced, narrowly fused with the preceding and broadly rounded 

 apically. Palpi; first segment long, incrassate, the second stout, 

 with a length three times its diameter, the third a little longer, 

 more dilated, the fourth a little longer than the third, with a length 

 four times its diameter. Mesonotum light brown, yellowish pos- 

 teriorly. Scutellum yellowish and carmine, postscutellum yellowish. 

 Abdomen a variable carmine, the basal segments clouded with fus- 

 cous, the distal ones pale yellowish. Wings hyaline, costa light 

 straw. Halteres yellowish basally, carmine apically. Legs a nearly 

 uniform yellowish straw, the articulations variably tinged with 

 dark carmine, the distal tarsal segments reddish or reddish brown; 

 claws stout, strongly curved, slightly swollen subapically, simple, 

 the pulvilli a little shorter than the claws. Ovipositor short, the 

 distal segment broadly oval. Type Cecid. 1227. 



Male. Length 1.5 mm. Antennae more than twice the length 

 of the body, sparsely haired, yellowish brown; 16 segments, the 

 fifth with a stem two and one-half times the length of the basal 

 enlargement, which latter has a length about twice its diameter. 

 Palpi; first segment slender, with a length fully foiir times its diam- 

 eter, the second dilated, with a length less than three times its diam- 

 eter, the third a little longer and more slender than the second, the 

 fourth one-fourth longer than the third. Mesonotum yellowish 

 brown, the submedian lines yellowish. Scutellum and postscutellum 

 pale yellowish. Abdomen ^^ellowish orange, the genitalia fuscous. 

 Halteres yellowish basally, fuscous apically. Coxae yellowish. 

 Legs a nearly uniform fuscous yellowish; claws slender, strongly 

 curved, the pulvilli a little shorter than the claws. Genitalia; basal 

 clasp segment short, stout; terminal clasp segment short, smooth, 

 narrowly oval; dorsal plate short, deeply and roundly emarginate, 

 the lobes narrowly rounded; ventral plate long, divided, the lobes 

 roiuidly truncate. Harpes stout, heavily chitinized and with a 

 heavy subapical spur. Cecid. a2 636. 



The structure of the male genitalia indicates a close relationship 

 to C. trifolii Felt from which this species may be separated by 

 the lighter color, the longer stems of the flagellate antennal segments 

 and the distinctly shorter terminal clasp segment.
