THE CANADIAN ENTOMOLOGIST 305 



The type species of this genus, K. viburni Felt is easily distinguished 

 by the almost trinodose character of the flagellate antennal segments 

 of the male; while the only other known species, the Peruvian K. 

 tonmsendi Felt, has much more slender flagellate antennal segments 

 in the male, the stems in this latter each having a length 33^ times 

 their diameter. Described from specimen in alcohol. 



Male. — Length, 1 mm. Antennae, 3^ longer than the body, 

 rather thickly haired, yellowish brown; 14 segments, the fifth having 

 the stems with a length \}/2 and two times their diameters, respec- 

 tively; circumfili and setae well developed. Palpi: First segment 

 short, subquadrate; the second with a length three times its dia- 

 meter, the third 3^ longer, more slender; the fourth 3^ longer than 

 the third. Mesonotum dark brown, the submedian lines fuscous 

 yellowish. Scutellum and postscutellum yellowish. Abdomen 

 yellowish white, the dorsal sclerites and genitalia somewhat fuscous. 

 Halteres pale yellowish. Coxae and femora mostly pale yellowish; 

 tibiae and tarsi fuscous yellowish. Claws slender, strongly 

 curved, the anterior unidentate, the pulvilli rudimentary. Geni- 

 talia: basal clasp segment moderately stout, the posterior ex- 

 ternal angles somewhat produced and bearing a group of three or 

 four stout setae; terminal clasp segment subapical, swollen near the 

 middle, curved; dorsal plate long, deeply and narrowly emarginate, 

 the lobes broad, narrowly rounded. 



Female. — Length, L5 mm. Antennae extending to the third 

 abdominal segment, sparsely haired, dark brown; 14 segments, the 

 fifth with a stem about ]/i the length of the cylindric basal enlarge- 

 ment, which latter has a length about twice its diameter; terminal 

 segment produced, the enlargement with a length three times its 

 diameter and apically a broad, knoblike appendage. Mesonotum 

 dark brown, submedian lines indistinct. Scutellum and post- 

 scutellum yellowish. Abdomen yellowish orange, the dorsal scler- 

 ites somewhat fuscous. Ovipositor short, yellowish, the terminal
