examination of one field of a"bout 15,000 hills, I "believe a 50 
per cent infestation would "be a very conservative estimate. I examined 
7 hills and found them to contain 2,^,11 ,2, U, 5, and 5 larvae res- 
pectively. Many of the larvae -"ere well up toward the tassel end 
in the old stalks. The larvae are "beginning to become lively and were 
crawling into uninfested portions of the stalks, 
A casual examination of old stalks which had teen washed in "by the 
high water revealed many larvae. On plots where the corn had "been 
cut last year I found hardly a larva. Cornstalks are scattered all 
over the farm, in the manure piles and fields and around hotbeds. 
It might "be of interest to note that corn and "broom corn have "been 
grown on these flats probably for the cast 50 years. With the exception 
of 1919 no definite plan of eradication work has ever been attempted 
in this area. 
ALFALFa 
MOUND BUILDING FEUHtlE A!^ (Pogonomyrmex occidental is. Ore scon)

a^cre alfalfa field at Windcm, and is ruining the stand. 
PEA APHID (Illincia pi si Kalt.) 
Kansas J. W. McColloch (April 20): A heavy infestation of the pea aphid has 
developed in an alfalfa field at Belvidere. The plants are turning 
yello^ and dying down. 
Oregon Sadie E. Keen (April 3): This insect was present in damaging numbers 
on several fields of vetch in an isolated side valley of the Willa- 
mette near Wapato. A fair percentage of the aphids were attacked by 
Ent omophthora aphi di s , and syrphid larvae were also present. 
CLOVER 
&L0VER LEA? WEEVIL ( Eyoera pu nctata Fab. ) 
Illinois W. P. Flint (April 20): Mr. J. H. Bigger reports finding one adult 
of the clover leaf weevil in a clover field in western Illinois. 
Larvae, mostly very small, are numerous in clover, alfalfa, and sweet 
clover fields throughout the State. 
Arkansas Dwight Iseiy (April 22) : The clover leaf weevil is quite common this 
year in the vicinity of Fayetteville. Weevil larvae are not abundant 
enough to cause what mieht be considered an outbreak, "but their 
occurrence in any numbers is unusull. Ordinarily they are a curiosity 
in this vicinity.
