EUROPEAN SPRUCE SAWELY 
The outstanding feature affecting the European spruce sawfly situation in 
the United States during 1940 has been the widespread and general mortality of 
larvae caused by "disease." The infestation in the severely defoliated areas 
of southern Vermont and southern New Hampshire has been reduced to a very low 
point. In many areas where there was a high population of overwintering 
cocoons during 1939“4o, and where heavy defoliation was expected in 19^0, ther 
was only slight feeding. Owing to the relatively low percentage of cocoons 
remaining in diapause in these sections, there is now a very low population 
of living cocoons in hibernation and most of those present are found on the 
outskirts of the areas formerly affected severely. There has been a consider- 
able mortality of pasture spruce and spruce growing in rather open growth in 
southern Vermont, but in closed stands mortality has been comparatively low. 
Severest mortality has apparently followed the 1938 feeding, and this may have 
been caused in pa.rt by the exceptionally dry season of 1939. The presence of 
larval disease was noted at a number of places in Maine in September, and very 
few living larvae could be found at points visited. On the other hand there 
is a considerable holdover of cocoons in Maine and, therefore, a considerable 
population of living cocoons in hibernation at many places. It is expected 
that adults will emerge from many of these cocoons next spring. Whether dis- 
ease will affect the larvae next year is problematical. A number of severely 
infested trees nea.r the mouth of the ^llagcnsh River at East Twin Erook have 
died. Notwithstanding the prevalence of larval "disease" and the reduction in 
infestation in the general area, some places have shown an increase in infesta- 
tion and have light to medium infestations at the present time. These include 
Mt, Cornell in the Catskills of New York; Green Peak, Mt. Equinox, and Mt. 
Abraham, in Vermont; North Pa.ck Monadnock, Crotched Mountain, Bald Peak, and 
Deer Mountain, in New Hampshire. (R. C. Brown, Bureau of Entomology and Plant

A PINE SAWELY 
Gilpinia f rutetorum E. is an introduction from Europe and apparently has 
been established in North America for many years, as it is now known to occur 
in the States of Connecticut, Massachusetts, New Hampshire, New Jersey, and Nev 
York and in a few localities in Ontario, Canada,. Until recently it had never 
attracted any attention in this country. Observations made in 1939 and 1940 
indicate that this species is increasing in some localities in New England and 
New York, although as yet it is not abundant enough to have caused serious de- 
foliation. The larvae feed, on red and Scotch pine. They are solitary in 
habit and their color blencls with that of the pine foliage, so they are easily 
overlooked unless rather abundant. There is one generation and at least a 
partial second generation each year in New England. (R, C. Brown, Bureau of 
Entomology and. Plant Quarantine, U. S. D. A.) 
LECONTE'S SAWELY 
Observations ma.de and reports received indicate that Neod iprion lecontei 
Eitch was more prevalent in 19^0 than usual in many localities in New England 
and New York. It rarely, if ever, causes extensive defoliation in natural 
stands, usually attacking a single pine tree or groups of trees growing more
