-283- 
except in Millard County, Utah, and in Douglas County, Nevada, where 
50 percent of the fields were severely damaged. Scouting revealed the 
weevil. in five counties not heretofore known to he infested; namely, 
Boston, Campbell, Sheridan, and Johnson in Wyoming, and Custer in South 
Dakota. 
California, A. E. Michelbacher (July 19) : In the San Joaquin Valley there was 
a marked increase in the alfalfa weevil population. On July U the average 
number of larvae collected per 100 sweeps of an insect net ran as high as 
785» This increase is probably the result of a partial second genera- 
tion. In the Pleasanton and San Francisco Bay areas the larval popula- 
tion has remained small. On July 12 the average number of larvae collect- 
ed to 100 sweeps in the most heavily infested field in the San Francisco 
Bay area was llU. In other fields larvae and adults have been difficult 
to find, Parasitization by Bathyplectes curculionis Thos. has dropped 
very rapidly. On July h it was less than 1 percent in the San Joaquin 
Valley, while in the cooler regions it was about 12 percent. 
POTATO LEAFHOPPER ( Empoasco fabae Harr. ) 
Virginia. F. W. Poos (July 20): More abundant on alfalfa this season than at 
any time during the last 8 years. All cuttings are severely yellowed 
and injured. The yellowing began to show up as early as June 8, although 
this insect first appeared the night of May 5» only 2 days earlier than 
in some, other years. 
Indiana. J. J. Davis (July 26): Alfalfa yellows, caused by the potato leaf- 
hopper, has been unusually prevalent since July 15 throughout a large 
portion of the southern half of the State and extending north, at least 
as far as Lafayette. Also less conspicuous to the northern border of 
the State. 
. . A CLOVER SEED CHALCID ( Bruchophagus sp.) 
Oklahoma. C. F. Stiles (July 22): The clover seed chalcid is quite numerous 
in the alfalfa-seed-producing area of Washita County. 
THREE-CORNERED ALFALFA HOPPER ( StictQcephala festina Say) 
Louisiana. L. 0. Ellisor (July): Is very abundant in fields of alfalfa in the 
southern part of Louisiana, In some fields at least 75 percent of the 
alfalfa plants are girdled. 
COWPEAS 
COWPEA CURCULIO ( Chalcodermus aeneus Boh. ) 
Georgia. T. L. Bisscll (July 23): The curculio is very destructive to cowpeas 
this year, unst'ung pods being hard to find. First-generation adults 
appeared in cages on July 18. 
Alabama. J. M. Robinson (July 2l): Active on cowpeas in central and southern 
Alabama.
