This is the second year in which collections were made in Hew 
iicxico during the adult survey. There were 3,526 specimens collected 
in 7 environments in which 58 species were represented. The dominant 
species, so far as economic importance is concerned, was Hi ssosteira 
longipenni s , although this does not show up in the collections. I.Ielanoplus 
f enur-ruhrun was the dominant species in alfalfa, corn, idle land, hears, 
and garden crops. M. nexicanus was the most numerous species in snail 
grains. 
Hatching of D. longipenni s began about May 1, and' continued 
through June. In the mid- Rio Grande area where M, f eriur- rub rum , M, 
differentialis , and II. bivi ttatus were d.ominant, hatching began the 
last week of April. In all areas, hatching was prolonged because of 
weather conditions. 
From the 1938 fall survey it was determined that an area of 
1,205,640 acres is known to contain egg beds of D. longipenni s , which 
will produce as large an infestation in 1939 as in 1938, perhaps larger.
