probably will not be as pronounced a decrease as was noted last year. 
The decrease of last year should tend to keep the general infestation 
below normal, and it is my opinion that wherever it is possible, in- 
fested tips should be removed before July 15. This will reduce the 
number of weevils of the new generation as well as cause an improve- 
ment in the final stand." | 
Infestation of secondary barkbeetles in Yellowstone Natioml 
Park,--T. T. Terrell, of the Coeur d'Alene, Idaho, field laboratory, 
reports 'the killing of several hundred small lodgepole pine trees 
along the highway tetween Obsidian Cliffs and Madison Junction, in 
Yellowstone National Park. The dead trees, which were evidently weak- 
ened by the action.of adjacent hot springs, occur‘in rather large 
groups and were apparently killed by an overabudance of secondary 
barkbeetles, Pityogenes knechteli Sw. The problem is further compli- 
cated by the presence of a species of Pissodes and of red turpentine 
beetles (Dendroctonus valens Lec.) in the roots and root collars. 
As a means of roadside cleanup, the trees were cut and burned in April 
80 as to destroy the insect broods before the first emergence in the 
hope: that the devastation will be checked. 
Stone flies.--J, €. Evenden reports an epidemic of stone flies 
(Plecoptera) defoliating cottonwood, elms, and cherries at Coeur 
d'Alene, ‘This is the first record of these insects appearing in the 
northern Rocky Mountain region in such numbers as to become a poten— 
tially serious enemy of shade trees, 
Lead_ cable borer empties wine barrels.--On April 26 Perez Simmons 
and C. K, Fisher, of the dried-fruit insect laboratory at Fresno, 
Calif., were requested to give advice in connection with damage being 
done to wine barrels in a Fresno winery by Scobicia declivis Lec. 
Beetles were boring in oak wine barrels, especially those stored near 
the windows, The favored point of attack was where the beveled edge 
of the barrel head meets the groove in the staves, but attack was also 
observed around the bung and at other points. The beetles have since 
been reported boring in redwood wine casks that held as much as 60,000 
gallons. The winery in question has lost two 50-gallon barrels of 
wine, each from the boring of a single insect. Here the damage done 
by an individual beetle amounted to $55 (50 gallons at $1.10 per gallon, 
including the Federal tax which was paid before the wine was lost).
