ELM LEAF BEETLE " .' 
The elm leaf beetle ( G-alerucella xan thomelaena Schr.), which increased 
to troublesome numbers in 1931, continued as a serious pest during 1332. 
In Massachusetts thousands of elm trees were seriously damaged. In Connecti- 
cut, although it did considerable damage in many towns and necessitated 
spraying, it was not so numerous as it was in 1931. Similar reports of seri- 
ous damage were received from the southern third of Maine. In New Hampshire, 
although present in noticeable numbers, it was not so serious as last year. 
It was also present in troublesome- numbers in Vermont. The conditions that 
prevailed in New England extended over the lower Hudson River Valley in 
Hew York. The insect was also reported in 'outbreak numbers throughout 
southeastern Maryland, south and east of Baltimore City and into Delaware. 
It appeared in destructive numbers in a number of cities and towns through- 
out western and southwestern Ohio and reports of lesser defoliation were 
received from scattered localities in Kansas, Kentucky, and Tennessee. On 
the Pacific Coast this pest was quite injurious to .'elms in the Yosemite 
Valley of California, in the Willamette Valley in Oregon, in the Yakima 
Valley of Washington, and around Parma in Canyon County, Idaho. The Fedsral 
parasite laboratory at Melrose Highlands, Mass., received a large shipment 
of txie egg parasite Tetrastichus xanthome la enae Rond. from Budapest, Hun- 
gary, this year. 
GYFSY MOTH AND BROWN- TAIL MOTH 
The first gypsy moth ( Porthetria dispar 1. ) egg clusters observed hatch- 
ing this year were seen on May 2. Hatching became general about May 9 and 
the maximum hatch occurred about the middle of the month. Up to the end 
of May 67 infested sites, with an aggregate of 885 egg clusters, were found 
in the barrier zone, the western-most point of which was 15 miles east of 
the New York State line in Connecticut. During the year over 40,000 acres 
were entirely defoliated and nearly 11,000 acres practically defoliated. 
No moths have been found this year in the area formerly infested in New 
Jersey where an eradication campaign was started ten years ago, nor has 
the insect been seen in this area since 1929. The moth was discovered late 
in July in northeastern Pennsylvania in an outlying mountain district near 
Pittston, Luzerne County. The infestation is now known to exist in eight 
townships; Pittston, Jenkins, Plains, Bear Creek, Wilkes-Barre, Kingston, 
and Exeter, in Luzerne County; and Lackawanna in Lackawanna County. 
During 1930 a fungous disease, Entomo nhthora aulicae Re;ich.« of the 
brown-tall moth ( Nygrnia nhaeorrhoea Don.) became epidemic in heavily in- 
fested orchards in parts of New Hampshire and Maine. In 1931 the disease 
was not so prevalent as in 1930 and this year we received reports of a 
general increase of the insect in Maine. 
SATIN MOTH 
During the past year the towns of Woodstock and Lincoln, N. H. , north 
of the quarantine line, have been found infested by the satin moth ( Stihp- 
np_tia salicis L. ). Within the infested territory severe defoliation was 
recorded as far north as Waterville, Bath, Brunswick, and Bangor, Maine, 
and Wakefield and Wolfeboro, N. H. There was some severe defoliation in
