GRAPE COLASPIS ( Colaspis bronnea Fab.) 
A. G. Ruggles (July 19). "In the southeastern county of the 
State our Mr. Mickel found this beetle doing considerable 
damage in cornfields." 
WHITE GRUBS ( Phvllophaga spp.) 
S. B. Fracker (June 26). "Well grown larvae of the 1923 brood 
common in the southern part of the State. Adults of other 
broods reported in Juneau County and several localities in the 
northern section." 
ALFALFA 
ALFALFA. WEEVIL ( Phvtonomus posticus Gyll.) 
Claude Wake land & D. B. Whelan (June 15). "This insect is less 
abundant than in 1921 in eastern Idaho where it has been on the 
decrease for the past three years. In southern and eastern Idaho 
the numbers of Bathyplectes curculionis Thorns, have increased 
greatly. The inference would be that natural enemies are aiding 
in reducing the number of weevils. In southwestern Idaho, the 
amount of injury varying from very slight to more than 50 per 
cent of the first crop. In this part of the State the insect is 
spreading. The great overlapping of the egg and larva stages in 
this region makes control work less effective and it may prove 
necessary to adapt a two-spray method of control. The pest is just 
becoming established in Canyon County." 
G» I. Reeves. "Mr. K. N. Pack reports finding weevils in a field 
at Lovelock, in Pershing County, on June 21." 
C. W. Creel. "Mr. Eldon Wittmer has just completed a survey in the 
Lovelock Valley and finds the weevils in rather large numbers on 
four ranches. These ranches are several miles apart, indicating 
a general distribution of the weevils in this valley." 
SPOTTED BLISTER BEETLE ( Epiaauta maculata Say) 
Claude Wake land (July 3). "County agent reports adult blister beetles 
as doing serious injury to blossoms and seeds of §rimm alfalfa, Th© 
specimens sent me are tentatively determined as .-Epicauta maculata. " 
. . PEA APHID ( II lino ia pisi g ait.) 
W. P, Flint (July 18), "This insect has been increasing during the 
last month and at present is killing clover in several counties 
in central Illinois." 
A. L. Strand (June 11). "On May 29, specimens of this aphid were 
sent in from Park City, where they were reported causing serious 
damage to alfalfa. By June 2, it was estimated that the crop in 
many alfalfa fields in that district was cut down 75 per cent.
