This is the first year that collections were made in Nevada, during 
the adult survey. There were 2,487 specimens collected in 4 environments, 
with the range collection amounting to only 43 specimens. The collections 
were made in the irrigated-crop districts in what is designated as the north- 
ern desert-shrub area. These irrigated fields arc subject to invasions from 
adjacent meadow grasses, where C annul a pcllucida. often breeds to great 
numbers locally. In the cropland listed here, lie lano plus devasta tor was re- 
corded as the dominant species and formed over half of the specimens col- 
lected for the State, 
General hatching was delayed by adverse weather until the end of Hay 
and continued through June, The outlook for 1939 shows Cannula pellucida 
numerous in grasslands adjacent to crops. Here, in a few places, the egg 
pods number as high as 350 per square foot.
