rapidly. Alfalfa in a field fall sown to "barley, near Walla Walla, 
also showed a large population of aphids. In some fields the percentage 
of alates in the copulation had already risen to 25 percent. Coccinellid 
"beetles were moderately abundant . particularly near the foothills of the 
Blue Mountains. 
Oregon. L. P. Rockwood (May 17): The pea aphid increased greatly in soir.e 
fields of Austrian winter field poas that were seeded late in September 
and early in October 1$3^« One field near Barlow showed a damaging pcp- 
ulation on May 17 . There probably will be some very localized damage. 
The backward spring, cool and with deficient precipitation in Mey, has 
been favorable to achid increase. (May IS): Most of the vetch sown in 
August and early in September was plowed under for green manure in fields 
and orchards by May 15« In some localities this vetch had been very 
heavily infested and some alates had moved out before it was "olowed under. 
Lr-ter sown vetch in seed and hay fields as a rule show only small aphid 
populations and these populations are increasing more slowly than those 
on Austrian peas. 
ALFALFA WEEVIL ( Hyper a postica Gyll. ) 
Colorado. G. M. List (May. 23): The alfalfa weevil promises to do very 
noticeable injury' in Mesa and Delta Counties. 
Utah. C. J. Sorenson (May 20): The alfalfa weevil is moderately abundant 
in Cache and Bear River Valleys. 
Utah and California. 0. I. Reeves (May 17): Alfalfa weevil larvae were 
collected at Willits, Mendocino County, Calif., on Aoril 23 and at Horn- 
brook, Siskiyou County, on May 2. We are also in receipt of specimens 
collected at Moapa, Clark County, He v. , or. April lU, which is also a new 
record for the occurrence of this weevil. (Bet. by A. G-. Boving.) 
California. A. E. Michelbacher (May 21): Larval populations in the Pleas- 
anton area have been the lowest of any year since our investigation of 
this nest was started. Ho counts as high as 1,000 larvae per 100 sweeps 
of an insect net have been collected. In this area Bathyplecte s cur - 
culionis Thorns, has built up at a tremendous rate since its introduction. 
In the field where it was first liberated at least SO percent of the 
large alfalfa weevil larvae collected on May 15 were found to be para- 
sitized. On May 2 in a field located some little distance from the 
point of introduction 15 percent of the large larvae collected were found 
to be parasitized. 
CLOVER LEAF WEEVIL (Hypera pu nctata Fab. ) 
Ohio. T. H. Parks (May 25): This insect has been very abundant in seme 
clover and alfalfa fields in the northern half of the State. Reports 
from Huron County reveal that one field of clover was clewed under because 
of the work of the weevil. Samples were also received from Portage County 
with the statement that it was seriously injuring alfalfa and clover.
