ROUNDHEADED PINS BEETLE 
In northern New Mexico Dcndroc ton-ur. convexifrons Hopk. increased greatly 
during the recent drought years and killed large numbers of pole-size and nature 
ponderosa pine trees. On the Santa Ee National Forest alone over 50,000 trees 
ware treated in 1937. The large amount of control work, together with improved 
growing conditions for the trees in 193” appeared to check the epidemic. (J. A.

MOUNTAIN FINE BEETLE 
In northern Idaho and western Montana this insect "became more generally 
destructive in stands of western white pine in 193S, especially on the Clearwater 
and Kootenai National Forests, Losses are still occurring in a few areas of 
lodgepole pine in the northern Rocky Mountains, and in white barh pine stands in 
and adjacent to Yellowstone National Park, although the widespread, epidemic of a 
few^ years ago in lodgepole has generally subsided. In Mount Rainier National 
Park, in Washington, the beetle was f ound in, epidemic numbers, and killed many 
large groups of western white pine. In California one area on the Tahoe National 
Forest, in the central part of the State, showed a marked increase of the beetle 
in sugar pine, and there was also an increase in the lodgepole pine infestations 
in Yosemite National Park. One infestation, however, reported in 1937 near Camp 
Nelson, in Sequoia National Park, died down in 193 e. (Division of Forest Insect

WESTERN PINE BEETLE 
In Oregon and Washington Dondroc tonus brevicorais Lee. v, as more aggressive 
in 193& than in the previous 2 years. Intensive surveys covering S8,5oO acres 
of sample plots indicated that losses would exceed 500 . 000,000 board feet of com- 
mercial pine timber. In Calif rrnia this season, infestations were on the increase 
for the first time since 193^. While this increase is general throughout the 
ponderosa pine type, it is more pronounced in the easts ide type of northeastern 
California, This build-up is rather striking because it has followed two seasons 
of heavy precipitation, which h-we resulted in improved conditions for tree 
growth, (Division of Forest Insect Investigations, Bureau of Entomology and Plant 
Quarantine, U, S. D, A.) 
DOUGLAS FIR BEETLE 
Destruction of Douglas fir continued to be severe in many areas throughout 
the entire Rocky .Mountain region. In parts of central Colorado, southern Utah, 
and northern New Mexico it is believed that from 50 to 70 percent of the Douglas 
fir stands have been wiped out, although no accurate surveys of losses have been 
made, (Division of Forest Insect Investigations, Bureau of Entomology .and Plant 
Quarontine, U, S. D. A.) 
ELM LEAF BEETLE 
Infestations were heavy in many localities through New England and New 
York in 193S, causing severe injury to the elm trees, particularly in the 
residential districts, 1 Specific areas where outbreaks are known to have occurred 
in 1938 include the townships of Augusta .'aid China, in Kennebec County, Maine,
