indicates a second seasonal generation, and this is possible since adult 
Phyllophaga of one species or another are active in the Southern States 
from the latter part of March until the middle of August. 
The species may prove to be an appreciable aid in the control of 
Phyllophaga in the Southern States.

SARCOPHAGIDS, INCLUDING DousrruL Recorps 
Several sarcophagids have been recorded in literature as parasitic 
on Phyllophaga adults, and we have occasionally reared them—and 
once an anthomyiid—in cages containing May-beetles, but in most cases 
it was plainly evident that the flies had hatched from maggots which fed 
only on the dead beetles. In all cases where these flies have been reared 
at the. Lafayette Laboratory, the cages were covered with wire-screen, 
permitting larvae or eggs to be thrust into the cage through the meshes. 
Furthermore, all such rearing records were from cages containing large 
numbers of beetles confined for parasites, and the dead beetles and 
abundant excrement were no doubt attractive to the scavenger flies. 
It might be noted that the sarcophagid larvae invariably left the dead
