ELM 
AM APHID ( Tuber culatus ulmifolii Monell) 
Iowa, G-. C. Decker (August 30) : For the past 3 weeks we have received 
numerous reports and inquiries from all sections of the State relative 
to the abnormal abundance of elm leaf aphids. Practically all of the 
elm trees that I have seen throughout the State have the leaves com- 
pletely covered with honeydew. 
Nebraska. M. H. Swenk (August 15-September 20): The outstanding pest of 
the period here covered was the elm leaf aphid. From August 27 to 
September 12, fro 1 " 1 Lancaster County north to Butler, Cuming, Platte, 
and Boone Counties, -and northwest to Pock Ccunty, many complaints wore 
received concerning the abundance of this aphid, which produced honey- 
dew in such profusion that it dripped from the leaves continuously, 
wetting houses, fences, walks, and vegetation under the trees. Mo- 
torists, especially, complained that it covered their windshields and 
cars and attracted great numbers of flies. 
FIR 
M APHID ( Dreyfusia piceae Ratz.) 
Vermont. H. L. Bailey (August 29): The balsam woolly aphid has been 
reported from Cabot, Mount Holly, and vicinity. A heavy infestation 
at Warren was observed on August 28. Many trees were dead. 
HEMLOCK 
A SAWFLY (Tonthredinidae) 
Oregon. F. C. Craighead (August) : J. A. Baal report? that an undetermined 
sawfly has recently been defoliating hemlock stands in western Oregon 
along the Cascade Range. Heavy defoliation of western hemlock oc- 
curred over an area of approximately 10,000 acres and lighter infesta- 
tion covered about a0,000 acres. Feeding for the yoa.r is about over 
and the larvae are rapidly constructing their cocoons. Hymenopterous 
parasites are busy searching out and parasitizing the cocoons/ Occa- 
sional sawfly adults are ncu appearing, and emerging parasites are 
very pbundant.' It is not believed that the defoliation this year 
will result in either heavy or widespread losses. 
HICKORY 
HICKORY BARK BEETLE ( Scolytus quadrisoinos us Say) 
Connecticut. W. E. Britton (September 2*4): Specimens fro- South Lyme 
were received on September k, with a statement that several trees have 
been injur ;d by the hickory bark beetle and show many exit holes in 
trunks and branches.
