National Forest in Oregon has produced large areas of dead and dying 
white fir and Douglas fir and larch during the year. 
HEMLOCK LOOPER 
The hemlock looper ( Ellopia fiscellaria Guen. , var. lugubrosa Hulst) 
during the past three years has built up a tremendous epidemic in Pacific 
and Grays Harbor Counties of Washington. During 1931, ninety million^ 
board feet of hemlock, with some western r^d cedar and Sitka Spruce, is 
estimated' to have been killed in Pacific County and another 10 million 
board feet killed in Grays Harbor County. A total of 162 million board 
feet has been killed in Pacific County during the' three years of the 
epidemic. 
LARCH CASE BEARER 
The larch case bearer ( Coleo-ohora laricella Hbn. ) was reported as 
severely damaging large stands of larch in Maine, Vermont, Massachusetts, 
and Pennsylvania. In three counties, in Maine the insect defoliated from 
50 to 100 per cent of every stand of. larch. , This damage continued into 
June, when re-ports of damage ,r ere also coming from Massachusetts, New York, 
and Ne^ Hampshire. A late brood of this insect defoliated larch in 
September in Ne^ York. 
BIRCH SXELETONIZER 
Birches' were very severely skeletonized by the birch skeletonizer 
( BuccuLatrix canadensisella Chamb. ) during the late shimmer and early fall 
in Maine, New Hampshire, Vermont, New York, Wisconsin, and Minnesota. In 
many places in the Adirondacks of New York State the birches were completely 
defoliated. In Maine hundreds of thousands of acres of birch in the north- 
ern paxt of the State ^ere browned by this insect. Tne birch leaf -mining 
sawfly ( Phyllotoma nemo rat a Pall. ) r "as associated with B. canadensisella 
throughout the New. England area and New York. 
A LEAP ROLLER , ' • . 
Although the leaf roller Cacoecia conflictana Walk, has been known 
for a good many years as a poplar pest in Western Canada, it seems to be 
a comparatively new pest in the United Sta.tes. This year we received a 
report of approximately 43,000 acres of poplar being defoliated in the 
Moosehead Lake district in Maine. The adults were in flight the last 
week in June and by the middle of July another brood of lajrvae were 
feeding on the poplars. 
ELM LEAF BEETLE 
Overwintering adults of the elm leaf beetle ( Gale rue el la xantho mela ena 
Schrank) were abundant in late April at Narrangansett, R. I., and during 
the latter part of 'June eggs and small grubs were very numerous in south- 
ern Ne^ England. Indications of the work of this insect "ere also observed 
during June in-'Wo^t Virginia, and it wa.B reported as very abundant at
