THE CANADIAN ENTOMOLOGIST 231 



tinguished from K. midtifila Felt, by the longer stems oi the flageU 

 late antennal segments as well as by differences in colour. 



Male. — Length 1 mm. Antennae probably one-half longer 

 than the body, thickly haired, yellowish brown; 14 segments, the 

 fifth having the stems nearly equal, each with a length one-half 

 greater than the diameter; terminal segment missing. Palpi; 

 first segment irregularly ovate, the second with a length over twice 

 its width, the third one-half longer than the second, more slender. 

 Mesonotum dark reddish brown. Scutellum and postscutelhim 

 yellowish. Abdomen mostly dark brown, yellowish brown apically. 

 Halteres yellowish basally, slightly fuscous apically. Coxae and 

 femora fuscous straw, the tarsi somewhat darker; claws stout, 

 unidentate, the pulvilli about half the length of the claws. Geni- 

 talia; basal clasp segment long, stout; terminal clasp segment 

 short, rather stout, swollen near the basal third; dorsal plate long, 

 broad, deeply and triangularly emarginate, the lobes rather long, 

 broad and narrowly rounded; ventral plate long, deeply and tri- 

 angularly emarginate, the slender, slightly diverging lobes narrowly 

 rounded and sparsely setose apically; style long, stout, strongly 

 curved. 



Female. — Length 1.25 mm. Antennae probably nearly as long 

 as the body, sparsely haired, yellowish brown; 14 segments, the 

 fifth with a stem one-fourth the length of the cylindric basal 

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

 terminal segment slightly prolonged and obtusely rounded apically. 

 Palpi; first segment irregularly ovate, the second rather slender, 

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

 longer and more slender than the second. Mesonotum dark brown. 

 Scutellum and postscutelhim yellowish. Abdomen reddish brown, 

 yellowish basally and with an oval subbasal spot dorsally. Halteres 

 mostly a light fuscous yellowish. Coxae and femora mostly 

 fuscous yellowish, the apical portion of femora, tibiae and tarsi 

 dark brown. Ovipositor short, the terminal lobes narrowly oval 

 and sparsely setose. Other characters practically as in the male. 

 Type Cecid. 1563.
