intermediate, and overtopped. The last group shows the least amount of 
injury. After ten years of age the relationship reverses and we find the 
overtopped class showing the highest percentage of injury and the dominant 
Class the lowest." 
In October a final examination of yellow pine slash was made by J. 
A. Beal on an April windfall area near Bly, Oreg. F. P. Keen reports: 
"Emergence of the western pine beetle from this type of material was 
found to be very spotty. It ranges from nothing to one hundred and sixty 
emerging beetles per square foot. On the whole the emergence from wind- 
thrown yellow pines is about what had been predicted during an earlier 
examination in the spring. Trees slightly off the ground and with a large 
part of their foliage intact showed better emergence than those which had 
less opportunity for drying out. Insect increase from this type of ma= 
terial can not be considered a serious menace to standing timber. * * * 
An examination of two yellow pine logging areas in Idaho was made to com~ 
pare Slash-insect conditions with those found in Oregon and Washington. 
They were not found to be noticeably different. In one operation where 
logging ceased in midsummer an outbreak of Ips oregoni Eich. (the Oregon 
pine bark beetle) is assuming large proportions. 
D. L. Parker, of the gipsy moth laboratory, Melrose Highlands, 
Mass., who has been collecting satin moth larvae from burlap bands put 
out in 20 towns extending from Ogunquit, Me., to Cranston, R. I., states 
that dissections of hibernating larvae, secured from bands put out in 16 
towns, have been made. "Apanteles larvae were found in all of the collec- 
tions and Meteorus larvae in three of the collections. The numbers of 
larvae from each town were rather small. Newmarket, N. H., was the site 
of a colony of Meteorus liberated in 1930 and in the collection from this 
point a satisfactory number of Meteorus larvae were found." 
The Budapest, Hungary, substation has been able to forward rather 
large shipments of birch leaves containing hibernation cells of the larvae 
of the leaf-mining sawfly (Phyllotoma nemorata Fall.) secured in Austria. 
In a summary Mr. Parker reports that "during the month 1,483 cells, 10 
hibernating larvae of a braconid parasite, and 20 leaves containing 
chalcid parasites, were received from Monichkirchen, Austria. Also, 
20,420 cells, 151 hibernating larvae of a braconid parasite, 20 leaves 
containing chalcid parasites, and 82 cells showing a fungus, were received 
from Freistadt, Austria." * * * P. B. Dowden states that 300 of the 
nemorata larvae have been dissected and that only one internal parasite 
has been found. He further states that the cells have been divided into 
three lots which will be placed in hibernation in different ways. 
R. C. Brown, Melrose Highlands, Mass., who has been studying the 
records of parasitism of "hibernating larvae" and "summer larvae" of the 
brown-—tail moth (Nygmia phaeorrhoea Don.) by the fungus Entomophthora 
aulicae Reich. for the period 1919 to 1931, says: "From 1929 to 1931, 
inclusive, the recorded percentages of parasitism by the fungus may be 
considered fairly indicative of the conditions existing in southeastern 
New Hampshire and southwestern Maine. The records show that from 1924 to
