In table 5 are listed hll species collected, with their hosts, in the 
same way the species are listed for the Gays Mills area in table 3, 
Summary of Pop ul ati ons and Host Preference s of the 
Principal Species from 1935 to 1941, Inclusive 
During the 7-year period 1935-41, inclusive, collections were made 
from 28 groves which, with 1 exception, were in the southern half of the 
State, The location of these groves is shown in figure 2, June beetles 
(according to the listing in the tables as they appear in the reports 
mentioned) were collected from 69 kinds of host plants, the identity of 
4 being uncertain. Oaks of the red oak group, and occasionally other 
closely related plants, were not separated as to species, owing to diffi- 
culty in making accurate determinations at night; therefore, over 70 
species are 'actually represented, A total of 56,344 beetles were collected. 
The most common beetles for the 7-year period were as follows;
