litfcle defoliation was noted; in Barnstable and Plymouth Counties, Mass., the in- 
festation was heavy in some localities. The wholesale cutting of webs over the 
entire infested area in 1935-36' and in 193 6-3 7 reduced .the infestation consider*, 
ably. Since this work was abandoned the infestation has increased rapidly in 
sone localities, (A. F. Burgess, Bureau of Entomology .and Plant Quarantine, 
U. S. D. A.) 
SATIN MOTH 
In general, the infestation throughout the infested area remains light, 
and most of the defoliation noted was confined to a few poplar trees. In Maine 
noticeable feeding was noted in only 2 towns. In 1 town in Cumberland County 
about 150 poplar trees were completely defoliated. In New Hampshire noticeable 
feeding "’as noted in 6 totals, in 1 town in Carroll County about L-l/2 acres of 
poplar growth were completely defoliated. In Vermont only a few trees, which 
were partially defoliated, were noted. In Massachusetts some defoliation was 
noted in 21 towns. (A, F. Burgess, Bureau of Entomology and Plant Quarantine, 
U. S. D. A.) 
local outbreaks of the satin moth occurred in the vicinity of Plymouth 
and Lebanon, N. H., and in Hartford, Vt. , in 1938* (J* V, Schaffner, Jr.,

FOREST TENT CATERPILLAR 
Observations in Vermont indicated that, in general, the infestations in 
Addison and Bennington Counties during the past summer were much less severe 
than in 1937, while in some parts of Windsor and Orange Counties severe defolia- 
tion was more apparent in 193S. Many sugar-maple orchards show the effects of 
severe defoliation in the last 1 to 4 years. In western Massachusetts and north- 
western Connecticut some rather heavy, local infestations were noted. It was 
also serious in parts of New York, particularly in Sullivan, Greene, Delaware, 
and Broome Counties, In southeastern South Carolina the defoliation of hardwoods, 
especially tupelo gum, was extremely severe, and this was of primary importance 
to beekeepers of the vicinity who depend on certain of these trees as a source 
of honey. In northeastern Michigan heavy defoliation was reported on an area 
covering several thousand acres. In northern Minnesota, however, where a very 
widespread epidemic has been in progress for several years, there was a tremendous 
mortality to the insect in 193^, owing to adverse weather conditions early in the 
season and to heavy paras it izat ion. Egg counts in September indicated a low de- 
gree of infestation in this region. (Division of Forest Insect Investigations,

SPRUCE 3UDW0RM 
In northern Minnesota the form that attacks jack pine increased in abund- 
ance and caused rather severe and widespread defoliation, although good growing 
conditions apparently prevented any tree mortality. In Colorado the form in- 
festing ponderosa pine continued in an increasing epidemic status in the central 
part of the State and was found to occur also in other parts of the Central Rocky 
Mountain region. In this sane region the form attacking Douglas fir and white 
fir showed an increase in 1935, but was not abundant enough to cause the death 
of infested troos. (Division of Forest Insect Investigations, Bureau of Ento- 
mology and Plant Quarantine, U. S. D. A.)
