aceris being named. Kieffer in 1896, holding that the genus as 
characterized by Meigen comprised a group, designated C.munda 
Winn. as the type. An examination by the writer, of specimens in 
Meigen’s collection deposited in the Natural History Museum of 
Paris, representing the four species originally assigned to this 
genus, showed that the specimens are in such poor condition that 
they can hardly be used to advantage in establishing the identity of 
the generic type. The form designated by Kieffer as the type of 
the genus, namely, C. munda Winn., unfortunately has not 
been characterized with sufficient fulness so that it can be sepa- 
rated from allied forms. Under the conditions, we are compelled 
for the present to treat Campylomyza Meign. as a supergenus, re- 
ferring thereto forms which can not be readily assigned to some 
of the more recent genera. Owing to the paucity of our reared 
material in this group, we have been unable to make a critical 
study of the generic characters, though the little data we have ob- 
tained in this manner would seem to justify the existence of the 
recently established genera.
