Injuries of Buffalo Tree-Hopper.—This insect (Ceresa buda- 
Zus) has become a serious pest in many parts of Ohio, It is only com- 
paratively lately that it has attracted special attention as a destructive 
insect, Professor Popenoe having described its work in Kansas about 
five years ago. During the last winter I have received twigs injured 
by the egg-punctures of the insect from three counties of the state, and 
in each of the orchards much damage had been done. Apples and 
BUFFALO TREE-HOPPER —a, back view; 4, side view, both slightly magnified; c, 
apple twig showing egg-punctur 
pears are both attacked. The insect is represented, slightly magnified, 
at æ and 2 of the accompanying figure, while at c is shown a twig par- 
tially covered with the egg punctures of the insect. —C. M. W. 
The Maple Bark-Louse.—This insect (Pulvinaria innumera- 
bilis), which was so destructive in the central western states about six 
years ago, is again appearing above the danger line. In some of the 
leading cities of Ohio it is present on the trees in great numbers, and 
is causing considerable alarm»
