Washoe County . — Adult populations indicated very slight damage in 1937, 
only one field rliaving a menacing population. 3. curculi oni s cocoons were very 
numerous, indicating that the parasite will be effective, as usual, next 
season -in minimizing the production of weevils. Results of the survey in this 
county, sampled on November 21-22, were as follows:

♦Only 100 dissected of total, 
Churchil l Coun ty.— Adult populations indicated no damage in 1937, no 
fields having menacing populations. B. c urcu li onis cocoons were rather numer-
