fore the apex, the fifth joining the posterior margin at the distal 

 third, its branch at the basal third. Halteres yellowish basally, 

 fuscous apically. Coxae and base of femora pale yellowish, the 

 distal portion of femora and tibiae dark brown; tarsi apparently 

 yellowish, the distal segments variably tinged with carmine. Claws 

 rather long, stout, slightly curved, with a long, slender tooth 

 basally; pulvilli longer than the claws. Ovipositor nearly as long 

 as the abdomen, the terminal lobes long, narrowly oval. Type 

 Cecid. ai58i.

This genus may be recognized by the 13 or 14 antennal segments, 

 there being a distinct tendency toward reduction and fusion with 

 the preceding in the case of the fourteenth segment. The male 

 antennae have the stem fully as long as the basal enlargement, 

 which latter is cylindric and presents much the same characters as 

 obtained in Rhabdophaga. The female antennal segments are 

 cylindric, sessile or subsessile and approach those of the female 

 Rhabdophaga. The palpi are triarticulate. The wings are small, 

 with the third vein nearly straight and uniting with the anterior 

 margin distinctly before the apex, the general appearance of these 

 organs being very close to that of Dasyneura, though the third vein 

 is not quite so heavy. The claws are minutely unidentate in both 

 sexes. The male genitalia present strong affinities with those of 

 Rhabdophaga. The ovipositor is unique, having a broad, stout,
