subcosta uniting therewith at the basal half. Halteres yellowish 

 transparent. Coxae dark brown; femora, tibiae and tarsi mostly 

 fuscous yellowish, the distal tarsal segment darker ; claws stout, 

 strongly curved, notched subapically, the pulvilli nearly as long as 

 the claws. Genitalia ; basal clasp segment stout, obliquely truncate ; 

 terminal clasp segment long, broadly rounded, dorsal plate short, 

 broadly emarginate, the lobes subtruncate. Harpes stout, bidentate. 

 Female. Length 2 mm. Antennae extending to the second ab- 

 dominal segment, rather thickly haired, reddish brown ; 11 segments, 

 the fifth subsessile, with a length about twice its diameter; eleventh 

 segment distinctly constricted beyond the middle, evidently com- 

 posed of two, the distal portion being narrowly oval. Palpi ; first 

 segment greatly swollen, irregularly oval, the second with a length 

 over twice its width, the third as long as the second, subtruncate 

 distally, the fourth one-half longer than the second. Mesonotum 

 dark brown. Scutellum reddish brown, postscutellum concolorous. 

 Abdomen sparsely haired, fuscous yellowish, the ovipositor slightly 

 fuscous. Costa dark brown. Halteres yellowish transparent, 

 slightly fuscous apically. Coxae dark brown ; femora and tibiae 

 fuscous straw, the second, third and fourth tarsal segments lighter, 

 the fifth reddish brown, the eighth abdominal segment ventrally 

 with a pair of submedian, subglobose bodies. Ovipositor short,

This group represents a form of specialization most easily recog- 

 nized by the series of subequal whorls of stout, curved setae on the 

 subsessile, flagellate segments, differing very greatly from the typi- 

 cal crenulate whorls so commonly present in Campylomyzine males. 

 The venation is typical of Campylomyza. The pulvilli are as long 

 as the claws. Males only are known. The type species is C a m p y - 

 lomyza hirsuta Felt.
