ADIPLOSIS 11. g. 
This genus is easily distinguished from Odontodiplosis Felt, to 
which it is closely related, by the stouter basal clasp segment and 
the total absence of teeth on the ventral plates or harpes.

HYPERDIPLOSIS fl. Q. 
This genus is erected for a form with simple claws bent at right 
angles and with a very long, broad, and very deeply and broadly 
emarginate ventral plate. The dorsal plate is deeply and roundly 
emarginate, the lobes being broadly emarginate and with the lateral 
angles greatly produced. 
Type and sole species Cecidomyia lobata elt, CG, 132. 
GIARDOMYIA n. g. 
This genus is erected for certain species doubtfully referred to 
Octodiplosis Giard. These forms, however, present marked differ- 
ences from the type of this older genus and a new genus has there- 
fore been founded. 
The genus Giardomyia comprises a number of small, yellowish or 
reddish forms having the simple claws bent almost at right angles 
and usually somewhat enlarged subapically. The ventral plate is 
long, slender, slightly expanded apically and roundly .emarginate, 
while the dorsal plate is short, triangularly emarginate and with 
the somewhat long lobes broadly rounded or even truncate. The 
mype species 1s G. pio vopihila Pelt [pl 38) fig. 2).
