-67 S- 
located in the southwestern part of the State, and on Mt, Ellen, Mt. Abraham, 
and Mt. Battell, in the central part of the State. In Lincoln, Vt,, where the 
infestation was heavy in 1937» it now seems to he somewhat reduced. In New York 
a number of nedium-to-heavy inf estations were found in. plantations of Norway spruce 
in Columbia, Dutchess, Ulster, Otsego, and Chenango Counties. Although no de- 
foliation was noticeable in the Adirondacks, this insect was quite numerous there 
in some of the older stands of spruce. In Maine, reports from State Entomologist 
Peirson indicate that there has been an increase in the intensity of the infesta- 
tion in the northern part of the State and in about 4 townships in Washington 
County. Between 5 and' 6 million parasites, Microplectron fuscipennis Zett., 
reared in the forest-insect laboratory of this Bvireau at New Haven, Conn., during 
the spring' and early part of the summer were colonized in spruce sawfly infesta- 
tions in Maine, New Hampshire, Vermont, and Now York. Larger numbers of this 
parasite were reared and liberated in portions of Maine by officials of that State.

AN INTRODUCED SAW ELY ON PINE 
Acantholyda erythrocephala L. is an introduced sawfly that feeds on the 
foliage of pine. It is widely distributed in Europe and is recorded from Chosen 
and Japan. It was first taken in the United States at Chestnut Hill, Pa., in 
1925, end 13 years- later it was found attacking white pine in Morristown and 
Somerville, N. J, Further records obtained in 1937 and 1938 have shown that the 
species is widely distributed throughout the northern half of New Jersey and that 
it occurs in Rockland and Orange Counties, N. Y., and in Monroe, Northampton, and 
Bucks Counties, Pa. The insect has been found to attack red, white, nugho, Swiss 
Mountain, Scotch, Japanese red, and Austrian pine in the United States, Red and 
white pine appear to be the most favored and Austrian pine the least. Although 
reported as attacking Larix . Picea, and Abies in Europe, this sawfly has not yet 
been- found to do so in the United States, despite the close proximity of trees of 
those genera to a heavily infested area. (C. W. Collins, Bureau of Entomology and 
Plant Quarantine, U, S. D. A.) 
A PINE SAWFLY 
Infestations of Neodipr ion sertifer Geoff., a European sawfly, apparently 
are increasing in intensity in New Jersey. Severe defoliation occurred in planta- 
tions of red pine, and on small groups of Japanese red, Scotch, jack, and mugho 
pine in Somerset County, whereas white pine and Austrian pine were fed aipon rather 
sparingly, even when growing j. n close proximity to the heavily infested species. 
In Now Jersey inf e- tat ions are known to occur in Hunterdon, Mercer, Middlesex, 
Morris, Somerset, and Union Counties, and, although considerable scouting was 
done in 1933, the species was not found outside of these counties. J. S. Houser 
reported this species as a serious pest of Scotch pine in Ohio in 193S. There is 
also a r. 'cord of this sawfly from Grayling, Mich., based on Larval identification.

SAWFLY ON RED PINE 
Although the sawfly Neodiprion sp. on red pine did not cause as much de- 
oliation in Massachusetts in 1938 as was anticipated early in the season, it still 
continues as a serious menace to red pine stands in New England. In Massachusetts 
many plantations of red pine on State forests, parks, State and municipal water-
