NEVADA 
This is the second year that collections were made in 
Nevada during the adult survey, A total of 5,583 specimens of 
grasshoppers were collected in 4 typical habitats and 23 species 
were recorded. In the 1938 collections Melanoplus mexicanus 
was called M. devastator , and in the 1939 collections, M. mexicanus . 
This species is the most important in the State, forming 56 per- 
cent of the total number of specimens collected; however, in the 
Smoky Valley areas M. occidentalis was the most important range- 
land grasshopper, but none appeared in the collections. 
According to Skoog, all of the specimens listed as Melanoplus 
mexicanus in the 1939 Nevada collections probably belong to the 
race bilit\iratus Walk. There is however, some conflicting opinion 
regarding the correct classification of this Nevada material, and 
until a definite understanding is reached on what to call it, it 
will all be called M. mexicanus.
