representative collections. Melanoplus mexicanus was the dominant ; 
grasshopper in the range land and some miscellaneous crops, including 
small grain and idle land. M. femur-rubrum vrafe dominant in sweetclover 
and alfalfa. Both M. mexicanus and M. infantilis were dominant in the 
mountain meadows. Por the infestations as a whole, M, mexicanus has 
decreased in relative abundance, as well as decreasing enormously in
