of 6 inches. The cage was left open above the ground so that beetles 
could move about and chcose plants for feeding. Early in July 65 
beetles were placed in each compartment, making a total of 1,040 in 
the cage. Counts of the beetles feeding in the different compart- 
ments were made with a flashlight on 10 evenings to obtain informa- 
tion on the host—plant preference. Late in the fall the ground in 
each conpartment was examined and the larvae were counted to obtain 
data on the chcice of oviposition places. In the accompanying table 
the nunber of beetles fceding on carrots is taken as 100, and in 
determining the choice of ovipositiun places the number of grubs 
> 
around orange hawkweed is taken as 100.

Estimates of the defoliation in the various conpartnents were as 
Bottows: Carrots, 100 percent; asters, 75 percont;. chrysanthemuns,
