10 per cent of the plants in the whole field were injured, although some 
parts of the field showed 50 per cent injured. The field of several 
acres was on gently rolling land which is subject to winter and early 
spring overflow from the Tualatin River. .In the western half of the 
field, where most of the injury occurred, the corn was planted early in 
May, but the eastern and little injured part was planted later. When 
the field was plowed late in the spring it was covered with a heavy growth 
of weeds in which the beetles had apparently oviposited heavily and the 
resultant larvae had transferred to the corn after the weeds were killed. 
The larvae found in the field on the lith were practically full grown 
and most of the feeding was over. It appeared that the late~planted corn 
had been subjected to less feeding than the earlier planted and was less 
injured. The location of the field on land that remained moist late in 
the season. in addition to the cool moist spring of 1932, apparently had 
favored the pest, as this type of injury has been unusual in our localityvaa 
Stages of alfalfa weevil in San Joaquin Valley.—-R. A. Blanchard, 
who made three weekly observations in June on Hypera postica Gyll. 
near Pleasanton, in the San Joaquin Valley of California, says: "On June 
2, larvae of all stages, as well as cocoons and adults, were present. 
On June 18, the adult stage was the most prevalent with only an occasional 
larva and cocoon being noticed. One egg mass was found inside a green 
stem on June 18. Considerable search for parasites did not reveal any." 
Unusual conditions increase injury by alfalfa weevil in Nevada.—- 
According to S. J. Snow, "The increase in the number of larvae and the 
injury continued during the first 10 days or two weeks of June and most 
of the fields in the vicinity of Fallon became heavily infested, and. 
except for remedial treatment by the common practice of dusting. would 
have been badly damaged. The cool and storm periods occurring through- 
out the spring wnd into June delayed the hatching of eggs and the matur- 
ing of the larvae and gave the appearance of repeated hatchings and at-— 
tacks. * * * This prolongation of the weevil attack increased the in-— 
jured area by a few thousand acres, making in all an estimated area of 
8,000 to 10,000 acres that should have been dusted. More than 5,900 
acres were dusted, mostly with the horse-drawn traction machines." 
caxerpillar parasite.—-0. M. 
Barnes, Tempe, Ariz., submits the following report on preliminary food 
ests with adult females of Anastatus Semiflavidus Gahan: "A preliminary 
series of tests to determine what effect the presence of honey water 
(l-to-4) solution, tap water. and Hemileuca oliviae (the host) eggs 
have upon the length of life of unmated Anastatus semiflavidus females 
has been completed. Forty-nine to 75 A. Ssemiflavidus females were used 
in each test. The honey water and tap water were supplied on cotton 
plugs; the H. oliviae eggs on grass stems. The tests were carried on 
during the period from January to June, 1932, in sa temperature control
