FOREST AND SHADE- TREE INSECTS 
GYPSY MOTH. ( Porthetria di spar L. ) 
H. L. Bailey (March 25): Egg masses of the .gypsy moth have 
been found in moderate abundance by scouts of the Vermont 
Department of Agriculture in Springfield, Rockingham, and 
towns south to the Massachusetts line. Observations in other 
sections point to scarcity or complete absence. 
BROWN-TAIL MOTH ( Nygmia phaeorrhoea Don. ). 
H. L. Bailey (March 25): Inspections in sections of the 
State most liable to reinf estation fail to reveal the presence 
of any winter webs. The insect lias not been found in the 
State for several consecutive years, though reinf estation lias 
been expected owing to spread in eastern Few England. 
EUROPEAN PINE SHOOT MOTH ( Rhyacionia buoliana Schiff.) 
T. L. Guy ton (March 13): Rhyacionia buoliana Schiff. was 
collected in 1930 by G. B. Sleesman and H. J. Fisher, nursery 
inspectors of the Bureau of Plant Industry, at the Pennsylvania 
Railroad Nurseries, Morrisville, and on Cheltenham Road, 
Chestnut Hill. Mr. Sleesman notes that the Pennsylvania 
Railroad Nurseries have 'a heavy infestation occurring among 
Scotch pine, but that the infestation at Chestnut Hill is of 
minor importance.

extremely prevalent this spring. Defoliation of cottonwoods* 
around Phoenix is severe. Severe injur", 7 to apricot foliage 
is reported in one instance. 
BIRCH LEAF-MINING SAWFLY ( Phyllotoma nemo rata Fallen) 
R. D. Glasgow (February 28): I think you will be interested 
to know that we found the European birch leaf-mining sawfly, 
Phyllotoma nemorata Fallen, to be abundant in Essex County last 
fall. Apparently this insect is now well established in the 
northeastern part of this State.
