When the beetle first awakens in the spring from its long winter 

 sleep, it flies to the elm trees just bursting into leaf and takes its first 

 meal by eating small, irregular holes through the young, tender leaves 

 (Fig. 2). After feeding a few days, the orange-colored eggs are depos- 

 ited on the leaves and these in a few days more hatch into the tiny 

 black and yellow grubs (Fig. 3). These grubs are the chief culprits. 

 They work on both surfaces of the leaves, although mostly on the under 

 sides, and eat so ravenously that in a few weeks nothing remains of the 

 leaves except a bare network of veins. The effect on the leaves is serious, 

 for they turn brown, curl, and finally fall from the trees. If the trees 

 are vigorous enough and the season is T propitious, a second crop of 

 leaves is put out, but these may meet the same fate as the first.

EXTENT OF ITS INJURIES 



It was estimated that in 1898 1,000 fine elms were killed in the city 

 of Albany and that in Troy the conditions were even worse. Similar 

 condition's obtained in dozens of other towns in the Hudson Valley 

 and along the Mohawk River. The writer has been told that a majority 

 bf the magnificent elms in Harvard Yard have been destroyed within 

 the last two or three years by the attacks of these small pests. There 

 is danger that through inaction and apathy the splendid elms of our 

 own City and Campus will suffer a like fate. Some of them are now 

 probably past any effort to save them.
