Darin?: the third wce^ in May there war, a sizable first "brood of the 
fall webworm ( Kyphant-ria cunea Drury) in the Georgia pecan orchards, and 
early in June this insect was also found on pecan in South Carolina and 
southern Mississippi. Over northern Mississippi this insect was compara^ 
tively scarce this year, and in general was not so serious as, usual through- 
out the South. Late in 'August it was reported as "being very abundant 
throughout the New England and Middle Atlantic States and as far South as 
Delaware. In Hew England it was more troublesome than it lias been any tine 
during the past 20 years.

The bagworm ( Thy r i do pt e r yx epheraeraef o mi s Haw. ) was reported as very 
abundant on arborvitae in George County, Hi.ss., in February. In June the 
insect was reported from Columbus, Ohio. -Daring July reports were received 
of serious damage to evergreens in Vermont, Pennsylvania, Delaware, Maryland, 
Virginia, North Carolina, and .Ohio. The bagworm was quite generally reported 
during August from Hew York westward to Indiana and Kansas, and southward 
to Mississippi and Florida. Reports continued to come in during September 
from this same general area.

The mountain pine beetle ( Den droc tonus monticolae Hopk. ), which has 
been ' sweeping through all of the .lodge-pole and white pine stands of the 
Pacific Northwest, is now decreasing in many sections, owing largely to a 
lack of suitable host material. The most serious epidemic in California 
is in the Medicine lake district of Shasta National Forest and there is 
evidence of' a decided increase in some stands of sugar pine in the Sierra 
Nevadas. In Oregon and- Washington epidemics have been noted during the 
year on the Fremont, Crater Lake, .and Deschutes National Forestsj the 
Klamath Indian Reservation; and throughout the Cascades of Washington. 
The outbreak in Mount Rainier National Park was completely under control. 
Increased losses occurred throughout the lodgepole pine forests of Montana 
and Idaho, and within the Beaverhead National Forest alone there were over 
twelve million trees destroyed in 1931. There was also a marked increase 
in losses in Yellowstone National Park. In central Idaho the infestation 
has spread throughout Salmon, Challis, Payette, Woisor, and Idaho National 
Forests, and it is now moving northward. Similar outbreaks continued to 
ravage the Pine Forest on the Kaniksu and Pend Oreille National Forests. 
In general the western pine beetle is not materially advancing in intensity 
of infestation. However, losses running as high as 8 per cent of the stand 
were observed along "the western slopes of the Sierra Nevadas in the Sierra, 
Stanislaus, and S : e-c[aoia National Forests, California. Throughout south- 
eastern and east a* n Oregon and Washington losses were particularly heavy 
on the Fremont, Deschutes, Ochoco, and Malheur National Forests, the 
Klamath Indian Reservation, and the private timber lands adjacent to these 
areas. In southern Oregon the infestation is increasing and reached 3 to 
4 per cent of the timber stand this year, while on the Ochoco and Malheur
