Jackson County, Or eg., ancV in from $ to 12 percent of the fields in Salt Lake, 
Duchesne, and Sevier Counties, Utah, Engle Valley in Baker County, Oreg., Mesa, 
Delta, and Montrose Counties, Colo.j Washoe .and Churchill Counties, Nev., and 
Fremont County, Wyo. ; negligible weevil damage occurred in the remainder of Utah, 
Oregon, Wyoming, southern and. western Idaho, the infested lowland district of cen- 
tral California, and in the infested area of western Nebraska. Expected damage 
in western Colorado failed to materialize because of winter reduction of weevil 
populations, coupled with excellent growing weather in the spring and advanced 
harvest of the first crop; damage in Box Elder and Salt Lake Counties, Utah, 
and in Jackson County, Oreg., was kept below the expected level by general cutting 
of the first crop at early maturity; damage exceeding the estimates resulted from 
greatlv belated cutting in the upper Snake River Valley of Idaho and in Douglas 
County, Nev. ; in other districts the damage experienced was in close agreement 
with that indicated by'the survey. Alfalfa-s eed-growing districts, where less 
frequent cutting tends to produce large weevil populations, also experienced dam- 
age during 1938. In Millard County, Utah, 30 percent of the fields were severely 
damaged and in southern Idaho (Jerome, Gooding, and Shoshone Counties) weevil dam- 
age seriously interfered with seed .production from the first crop. Scouting by 
the alfalfa weevil laboratory staff, in cooperation ™ith State organizations, re- 
sulted in original discovery of the alfalfa weevil in 12 additional counties, viz; 
Pitkin, San Miguel, and Weld in Colorado; Banner and Kimball in Nebraska; Douglas 
in Oregon; Big Horn, Hot Springs, Laramie, Park, and Washakie in Wyoming; and Big 
Horn County in Montana. This is' the first field infestation discovered in 
Montana, A detailed account of the survey has been, issued as a Supplement to 
Insect Pest Survey Bulletin, No. 9. December 27, 1938. (J. C. Hamlin and W. C.

VETCH BRUCHID f 
The vetch bruchid biegan emerging from hibernation quarters' in North 
Carolina in April, the first adults being swept on April 13. They were present 
in all vetch fields by the first of May and, owing to the mild winter^ the bruchid 
population was about the same as it has been in the last 4 years of observation, 
even though fewer adults were produced in the 1937 seed crop. Egg deposition 
began on May 4 and the last viable egg wa^ found in the field on July 2, There 
wero two definite peaks of oviposition this year, as a result of unseasonable 
weather in the latter part of May. The first peak was reached on May 19 and the 
next peak on June 6, Much hoavier egg deposition was noted this year, as compared 
with last year. This can be accounted for by the favorable spring and the slower 
maturity of the vetch’ crop, which prolonged the period when pods wore available 
for egg deposition* In 1937 on the row of Vicia vlllosa in the vetch Vrorietal 
resistance experiment the daily egg count on 50 pods selected at random produced 
a total of 2,947 eggs during the period of egg deposition, while this year the 
same variety had a total egg .count of 6 , 466 . The weevil population in the 1933 
crop of seed is just a little above the average of 50 percent usually prevalent in 
North Carolina, the average this year being 53 percent. The maximum infestation 
found in any field w as percent and the minimum 2 percent. 
During the course of the voar the known distribution in the East was in- 
creased by four counties in North Carolina, namely, Chatham, Surry, Wake, and 
Wilkes, In August the insect was discovered for the first time on th'e west coast 
m a number of vetch fields in the northern Willamette Valiev of Oregon; in
