has increased, and the volume of timber killed in 1930 (over 50,000 
feet b. m.) was greater than that for any other year since the area was 
first cruised in 1927. The winter brood for 1930 showed 52 per cent 
of the bark surface infested by flathead borers and only 28 per cent by 
the western pine beetle- a distinct reversal of conditions found at the 
inception of control work in 1928-29." 
R. C. Brown, of the gipsy moth laboratory, Melrose Highlands, 
Yass., reports as follows concerning observations made on a trip to 
a village in the township of Dighton, Mass.: "Several large elms in 
the churchyard and nearby were heavily infested by the elm leaf bee~ 
tle (Galerucella xanthomelaena Schrank) last summer. According to the 
inhabitants of the village great numbers of the beetles invaded the houses 
and church in the fall in search of hibernation quarters. Large numbers 
were swept up and destroyed in the church and upper rooms of the houses.* 
* * * Qn December 2, 1931, a careful search was made in near-by stone 
walls and under débris piled near the church, and a large number of dried 
leaves were examined, but not a single hibernating beetle was found. These 
observations and others made last fall lead to the conclusion that the 
number of beetles which hibernate outside of buildings is practically 
negligible. This suggests the possibility of contriving some type of 
a beetle trap which might be employed to catch the beetles as they enter 
or leave buildings." 
J. A. Millar, Melrose Highlands, submits "figures relative to the 
extent to which collections of gipsy moth egg clusters, taken last fall 
by members of the staff at various points in New England, were parasitized 
by Anastatus disparis Ruschke and QOoencyrtus krvanae How. Mr. Millar's 
data show that the parasitism by A. disparis ranged from 1.8 to 22.79 
per cent (being lower than for last season) and that the parasitism by 
QO. kuvanae ranged from nothing to 0.69 per cent. 
C. E. Hood, who has been conducting spraying experiments against 
the beech scale (Cryptococcus fagi Bar.), reports that practically 100 
per cent kill has resulted from spraying (on November 10) with 7 and 
o per cent solutions of miscible oil. Mr. Hood says that in December 
"On the check trees the scales appear healthy, are a golden yellow in 
color, and a large percentage of them are living." 
F. W. Sellers, Budapest, Hungary, says: "Dissections of larvae 
of the larch case bearer (Haploptilia laricella Hbn.) collected in Aus— 
tria have shown parasitism by what appear to be three species. Two of 
these are perhaps braconids, and the other a chalcid. A collection of 
larvae made at Kamel yielded the most parasites. Fifty were secured from 
180 larvae." 
CEREAL AND FORAGE INSECTS 
Correction: The species of Microbracon reared by H. R. Painter 
from Phytonomus nigrirostris Fab. collected at Roanoke, Ind., as re— 
ported on p. 19 of the October Monthly Letter, was M. tenuiceps Mues. 
and not M. tachypteri Mues.
