the insect in and around Rochester, N. Y., is of most interest, as this area is 
so far removed from territory previously known to he infested. Other interesting 
records have to do with Columhus, Ohio, Sag Harbor, Long Island, N, Y.., and Con- 
cord N. H. S. multistriatus has also been taken during the year at several 
places in Connecticut, which extends the known infested area in that State some- 
what farther ea r t along Island Sound. The number of S,. mult ist r iatus adults 
collected from elm trap trees at six New Jersey locations in 1939 was less than 
the number collected at the same locations in 1938 under similar collecting method* 
SPRUCE BUDWORM 
■Outbreaks of the spruce budworm in the Douglas fir and white fir stands in 
central and southern Colorado are spreading to new areas and in many of the old 
areas the defoliation has become so severe that many trees will be killed. In- 
festations in ponderosa pine have been found in new areas but in the older out- 
break areas the defoliation does not appear to be as severe as the previous year. 
PANDORA MOTH 
■ The epidemic of the pandora moth ( Coloradia pandora Blake) in lodgepole pin* 
on the Arapaho National Forest, in Colorado, was greatly reduced during the last » 
year by three natural factors.’ An unusually cold winter killed many of the 
second- ins tar larvae that overwinter on the branches, A wilt disease of the lar- 
vae 'was effective in reducing the survivors of the winter. Abnormally high tem- 
peratures and dry, hard soil killed many of the mature larvae while they wore 
attempting to enter the soil to pupate in July. 
hemlock looper 
The severe epidemic of the hemlock looper ( Ellopia fiscellaria Guen. ), whici 
in 1937 appeared throughout the Alpine fir stands of northern Idaho and western 
Montana, was reduced through natural agencies to a normal condition in 1939* A 
number of parasites played a part in this r duct ion of which Pharynoldella n. sp. 
was most important. Although the first known record of this insect within the 
northern Rockies, the presence of its natural enemies indicate? that it is in- 
digenous to the region. 
DOUGLAS FIR TUSSOCK MOTH 
As predicted last year, infestation of the Douglas fir tussock moth ( Hemero - 
campa pseudotsugata McD. ) increased materially. In the infestation centering abo - > 
Rudio Mountain of the Malheur National Forest many Douglas firs and true firs wero 
completely defolioted and are expected to die. Understory ponderosa pine was alsc 
defoliated where infestation was heaviest. In this area a remarkable drop in 
population occurred during the late larval stages, which will probably result in 
a light infestation in 1940, An extensive new outbreak of this defoliator was 
discovered near Spray, Or ig. , on the Umatilla National Forest. There, only parti;* 
defoliation was observed but probably there will be an increase next season. 
GREAT BASIN TENT CATERPILLAR 
An outbreak of the great basin tent caterpillar ( Malacosoma fragilis Stretc> 
became widespread on the Deschutes National Forest, Oreg. t where it caused severe 
defoliation of bitterbrush ( Purshia tridentata ), the most important native browse 
plant of the western ranges. This infestation was first observed in 1937 end de-
