second instars. Hatching was most connon on field end road margins 
and south slopes. Only injury observed was : on May 10 at Elgin, on 
alfalfa-field margins. On May 22 a heavy hatch was occurring on 
some eggbeds near Minersville, 'as many as 300 nymphs per square yard 
being found. Among the species arc M. . diffcrentialis , Aulocara 
elliotti Thos.,' and Hlppi-scus corallipes Hald# Parasitize~tion by 
bee fly is narked, sometimes 8 per square foot, attacking unhatched 
eggs of Cannula pellucida Scudd# we st of Ephraim, in central Utah. 
Idaho, B. K. Gaddis and assistants (April 21-26): M, nexicanus and M, 
f enur- rub run Beg, are reported as beginning to hatch in the irrigated 
■ sections of the eastern pant of the State# Second- and third-instar 
nymphs of Aulocara sp. were observed. (May 4-10 ): Egg concentrations 
of £. pellucida occur in the Ola section of Gem County, and in the Hill 
City area of Elmore County in the western part of the State# 
Nevada. B. M, Gaddis and assistants (May 11-17): M, occidentalis Thos, 
was reported to be hatching' in Smoky Valley, in the southern portion 
of Lander County, in the central part of the State, on April 28, which 
liras 2 to 3 weeks later than in 1940 and from 4 to 5 weeks later than 
in 1939 • Eirst- and second-ins tar nymphs of M. occidentalis were ob- 
served. in the Dunply area of northern Eureka County on May 6. Cannula, 
pellucida, was hatching in Douglas County, southwestern Nevada, on May l4". 
California. S. Lockwood (May l): Grasshopper hatch has been reported as 
irregular from El Centro, Imperial County in the southeastern part of 
the State. M. nexicanus now ranges from third-instar nymphs down to 
first instar, with the hatch incomplete. Infestations are consider- 
ably ' lighter than a year ago. M. nexicanus hatching is incomplete in 
Riverside County, and infestation is spotted and considerably lighter 
than last year. A severe infestation of M. devastator Scudd, and 
Oedaloono tus enigma Scudd, has occurred in the area from Arrowhead 
across north to Vcrdemont in the Cajon Pass area-, thence west around 
the foothills to Rialto, North Fontana., and close to Colton, all in 
San Bernardino County in the southern part of the State. Grasshoppers 
are confined to brush and range land. In the low elevations they run 
more than 100 nymphs to 10 sweeps of an insect net, even on an over- 
cast day. Infestation is heavier than last year. M. devastator nymphs 
are first and second instars with an occasional third. 0. enigma 
ranges from second to fourth. Range grasses are relatively high, 
which will hold the grasshoppers in place for some tine. Inspections 
in Orange County show that M. devastator and 0. enigma are present in 
the first and second instars on two ranches. These are relatively 
large areas and will need considerable attention. Inspections made 
last week in Los Angeles County show that the hatch is not far enough 
along to give a true picture# * In Kern County, M. devastator nymphs 
have been reduced fron one-half to one-third the number present last 
year. General infestation of lighter numbers than for the last 2 
years occur from a ranch east of Edison, south along the foothills 
for approximately 30 niles past Co mane hi Point, 
S. Lockwood (May 15 ): Farther north foothill range lands in Colusa 
and Yolo Counties are now infested, with M. devastator ranging fron
