M, C. Lane (May 27); Wireworns have b^en active during 
this month attacking early seed potaotes and spring seeded 
onions. More or less damage has been reported upon nearly 
all garden truck crops around .'alia .'alia. Adults have been 
active since April 1st., with peak of flight about first 
week in- May. Adults of Fheletes canus Lee. ".ore obtained 
from blossoms of young cherry and pear tre^s where some feed- 
ing damage was noticed. Thousands of this species rere col- 
lected from seed heads of rhubarb for our rearing work at the 
laboratory, emergence of P. occidentalis Cand. was less nu- 
merous than of P. canus , and practically no feeding by this 
species was noted. Other species of wireworm adults collected 
this spring are Melanotus orcgonensis Lee, Ludius ir.flatus 
Say, Lolopius lateralis Esch. , Cardiophorus tenebrosus Lee, 
and Pheletes venablesi '.Tick.

WHITE GRUBS ( phyllophaga Spp.) 
C. 0. Ccnptoa-(June) : Adults of Phyllophaga fuse a Froel. 
were observed in heavy flights May 28, 29, 30, and 31, in 
Cook County. Many oak groves or scattered oaks in pastures 
throughout central and north-central Illinois have been almost 
completely defoliated. 
E. L. Chambers (June 21): White grubs are scarce, but 
beetles are very abundant, defoliating many oak, poplar, elm, 
and other trees in spots. 
A. G-. Rugbies and assistants (June): Although June beetles 
are being observed in large numbers, white grubs are very 
scarce in the fields this year . 
C. J. Drake (June): Adults are from moderately to very 
abundant in the eastern part of the State. 
H. E. Jaques (May 31): Adult May beetles seem to have 
been delayed in making their appeaance thi s spring but dur- 
ing the past 10 days or two weeks have more than made up for 
lost time. Their choice food plants are fairly covered 
with them on warm nights, and timber and shade trees, as well 
as many rose bushes, are suffering severely in defoliation. 
At least 10 species are represented in those that are now out. 
M. H. Swenk (May 15-June 15): Adult May beetles of several 
species have been flying abundantly during the period here 
covered, presaging a return of serious "hite-grub conditions 
in 1930.
