PHYLLOPHAGA POSTREMA Horn 
The writer has had no opportunity to examine the types of P. pos- 
trema or P. quadrata Sm., but a study of our collections indicates that 
they are identical. The former is known only by the male and the latter 
by the female. 
Types of all the species and varieties described in this paper are de- 
posited in the collections of the Illinois Natural History Survey; par- 
atypes of the same, in the United States National Museum and in the 
writer’s collection; and paratypes of perlonga, mississippiensis, pearliae, 
soror, foxtt, and comosa have been deposited in the collections of the 
American Museum of Natural History and of the Philadelphia Academy 
of Sciences. ;
