insect is not sufficiently destructive to warrant adopting such 
measures. 
Elm leaf beetle (Galerucella luteola Mull.). This im- 
ported species continues to be a serious pest of elms, particularly 
in the Hudson valley, many of the elms of Yonkers, Poughkeepsie, 
Hudson, Albany, Troy, Schenectady, Schuylerville and Ithaca and 
probably other localities in the State being very badly injured. The 
work at Schuylerville and Schenectady was exceptionally severe and 
the same is also true of its operations at Ithaca. The major part of 
the injury in Aibany at least was due to delay in appointing a city 
forester and getting the spray apparatus into operation. Further- 
more, it is very difficult to secure men who can be relied upon to 
do thorough work. Experience has demonstrated beyond all ques- 
tion the practicability of keeping the elm foliage practically intact, 
even in localities where the pest is very abundant. It is for public 
spirited citizens in affected localities to insist upon the maintenance 
of such a standard. : 
The observations of the past season show in a most striking 
manner the extremely local character of this pest. The badly in- 
fested area in Albany has been restricted for the past decade to the 
older and more thickly settled fourth of the city. A study of con- 
ditions in Schenectady showed a similar restriction, the destructive 
work of the pest being limited almost exclusively to a small section 
of the older part of the city, in the vicinity of Church street and 
not extending in any direction more than to blocks from the center 
of the infestation. Furthermore, the most severe injury was 
noticed upon a group of elms near the open belfry of a church, 
clearly indicating that the insects winter most successfully where a 
structure of this kind affords abundant shelter. 
Bag worm (Thyridopteryx ephemeraeformis 
Haw.). New York city and its vicinity represents about the north- 
ern extension of this species, as a rule. It was somewhat surprising, 
therefore, to receive healthy larvae from Germantown, only about 
40 miles south of Albany. Mr T. F. Niles, who sent in the speci- 
mens, states that no young trees have been set in this locality within 
the past 2 years nearer than a quarter of a mile, consequently it 
would seem as though the species was able under certain conditions 
to maintain itself considerably farther north than has heretofore 
been supposed possible. 
Fall webworm (Hyphantria textor Harr.). This com- 
mon species has been unusually abundant in some portions of the
