NATURAL ENEMIES '. PARASITIC INSECTS. 
151 
In the last instance, at Barnesville, Ga., 74 of these parasites were 
reared from 1,115 curculio larvae from peaches, entering the soil 
August 6 to 13. The parasites from this lot emerged August 30 to 
September 15, the females emerging slightly later than the males on 
an average. In this case the percentage of parasitism by C. in<&- 
quipes was 6.63.

Cholomyia inxquipes, a fly reared abundantly from the plum curculio at Barnesville, Ga.: Adult 
on left, puparium in curculio larval skin on right. (Original.) 
The puparium of Cholomyia (fig. 30) is formed in the soil, within 
the skin of the host larva, the adult parasite, on emerging, breaking 
through the posterior end of the old skin. 
Pegomya fusciceps Zett. 
This anthomyiid fly has appeared many times in jars and cages in 
which the plum curculio was being roared. But it is unlikely that 
this species is ever parasitic, and its presence may in moel cases be 
accounted for as a feeder upon the more or less decayed fruit in com- 
pany with the curculio larvae.
