to shade trees by the leopard moth, Zeuzera pyrina Linn., which is 

 boring in the branches of various kinds of trees in the cities, and by 

 the woolly maple leaf scale, Phenacoccus acericola King, which here 

 confines its attacks chiefly to the sugar maple. The maple borer, 

 Plagionotus speciosus Say, is still a serious pest of sugar maple shade 

 trees in towns and cities, over sixty adults being taken by the gypsy 

 moth men in Wallingford during their work of turning bands. Though 

 this insect is not considered as a forest insect, the writer has seen its 

 damage in wooded areas of perhaps twenty-five acres in extent in 

 western Massachusetts and in New Hampshire. 



The elm leaf beetle has done great damage in certain parts of the 

 state, especially where the elms were not sprayed last season; but in 

 New Haven, Milford, and other places where a systematic spraying of 

 the trees was practiced in 1909, beetles have been rather scarce, though 

 in most of these towns spraying has again been practiced this year. 



Scientific Notes 



BuccuLATRix CANADENSisELLuA. Chamb. — The work of this Tineid, which has this 

 year been very abundant and destructive in many parts of New England, has been 

 observed on the birches (Betula populifolia), throughout Rhode Island, up through 

 Eastern Massachusetts, west as far as Springfield, Mass., and north to Manchester, 

 N. H., and to about 12 miles west of Nashua, N. H. According to advices sent us 

 by Captain Philbrook, it is present in Maine as far east as Augusta and he has also 

 noticed it in Waterville. At Melrose Highlands, where it has been very common, 

 the small white moulting cocoons of the larvae were first noticed on the leaves of the 

 birches on August 29. The pupal cocoons were first observed in the field Septem- 

 ber 9th, and on the 10th the larvae, which had been abundant on the leaves a few 

 days before, had almost all disappeared. As a result of the work of this insect, the 

 leaves of the majority of the birches in the woods about here are prematurely dead, 

 brown and shrivelled, and this condition has been reported from a great many 

 localities throughout the infested area.
