PARADIPLOSIS fl. g. 
This genus is separated from Cecidomyia principally because of 
the peculiar structures presented by the male genitalia. The basal 
clasp segment is short, stout and broad, while the terminal clasp 
segment is short, stout and apically with a broad, chitinized serrate 
margin. The dorsal and ventral plates are short, broad, each rather 
deeply and narrowly emarginate; style short, stout. The third vein 
unites with the margin at the apex of the wing. The palpi are 
quadriarticulate and the claws simple.

OBOLODIPLOSIS Nf. Q. 
This genus has been erected to include a remarkable form which 
diverges widely from the ordinary type of Cecidomyia in the male 
genitalia. The terminal clasp segments are greatly produced, being 
nearly 1% longer than the basal clasp segment. The dorsal plate is 
greatly expanded, nearly divided, the lobes being orbicular, while the
