Members of this genus may be separated from Porricondyla by 

 the slender abdomen recurving dorsally, the much produced ovipositor 

 and the strongly sinuous basal portion of the third vein. 



The type of this genus, C. binotata Kieff., has at least 

 18 antennal segments in the male, the fifth with a stem one-half 

 longer than the cylindric basal enlargement, the latter with a close 

 subapical whorl of extremely long, slender setae, suggesting the 

 crenulate whorl of Campylomyza. Palpi very long, quadriarticu- 

 late. Claws short, evenly curved, simple, the pulvilli as long as 

 the claws. Basal portion of the third vein strongly curved, con- 

 spicuous. Genitalia triangular, the terminal clasp segment rather 

 long, swollen near the middle, coarsely dentate apically ; dorsal plate 

 short, broad, broadly and triangularly emarginate, the lobes broadly 

 rounded, setose; ventral plate long, incised, the lobes long, narrowly 

 rounded, setose; style short, stout. The female has at least 28 

 antennal segments, the fifth with a stem one-third the length of the 

 cylindric basal enlargement, which latter is slightly constricted near 

 the middle, bears subapically a rather scattering whorl of long setae. 

 The ovipositor when extended is nearly as long as the slender abdo- 

 men; terminal lobes triarticulate, the first and second segments 

 subquadrate, the terminal one narrowly oval, tapering, setose. 

 Cotype in the collections of the New York State Museum. Several 

 species have been provisionally referred to this genus.
