THE CANADIAN ENTOMOLOGIST 229 



segment somewhat produced, with a length nearly one-half greater 

 than its diameter and sometimes partly fused with the preceding. 

 Palpi; first segment narrowly oviil, the second one-half longer, 

 tapering to a subacute apex. Mesonotum shining reddish browii, 

 the submedian lines sparsely haired. Scutellum and postscutellum 

 shining yellowish brown. Abdomen mostly dark brown basally, 

 the segments sparsely margined sublaterally and posteriorly with 

 a broken line of white scales, the fifth to the seventh segments 

 sparsely clothed with fuscous scales, the latter hardly obscuring 

 the reddish orange colour of the abdomen; discal spot white, 

 elongate and near the middle of the wing. Halteres fuscous 

 yellowish basally, fuscous aoically. Coxa^ fuscous yellowish, 

 femora and tibia? fuscous yellowish basally, fuscous apically; 

 tarsi a nearly uniform dark brown ; claws long, rather slender, 

 strongly curved, unidentate, the pul villi nearly as long as the 

 claws. Genitalia; dorsal plate deeply and triangularly emarginate, 

 the broad lobes broadly and rather irregularly rounded; ventral 

 plate long, broad, broadly rounded. 



Female. — Length 2 mm. Antenna? fuscous basally, yellowish 

 or reddish apically, sparsely haired; 16 segments, the fifth with a 

 length about equal to its diameter. Palpi; the first segmsnt with 

 a length nearly twice its diameter, the second a little longer than 

 the first, abruptly tapering distally. Mesonotum dark reddish 

 brown. Scutellum and postscutellum dark brown. Abdomen a 

 nearly uniform brownish black, the ovipositor fuscous yellowish, 

 about one-third the length of the abdomen, the terminal lobes 

 being broadly ovate and thickly setose. Halteres yellowish 

 transparent basally, brownish black apically. Coxa^ and legs a 

 nearly uniform brownish black, the posterior tibia^ narrowly and 

 indistinctly annulate distally with white. Type Cecid. a2585. 



Kalodiplosis, n. g. 



The unidentate, heavily toothed claws, the rudimentary 

 pulvilli, the third vein joining the margin at or slightly before the 

 apex of the wing, the triarticulate palpi, the heavy, rather thick 

 and moderately short circumfili, and the long dorsal and ventral 

 plates, the latter deeply emarginate and with relatively narrow 

 lobes, serves to distinguish this genus from Dicrodiplosis Rubs, 

 and the series related thereto. Type Dicrodiplosis multifila Felt.
