THE ELM-LEAF BEETLE IN NEW YORK STATE T 



the distribution of the beetle along the lines of travel. In 1879« 

 it was abundant and destructive at Newburg; 12 years later it 

 was reported to this office from Poughkeepsie, in 1890 from Hud- 

 son, in 1891 from New Baltimore and in 1892 it had reached 

 Albany and Troy. It was found at Mechanicville in 1896 by Dr 

 L. O. Howard, of Washington, D. C. That same year the larvae 

 were abundant at Averill Park in the town of Sand Lake about 

 seven miles southeast of Troy, the beetles evidently having been 

 transported thither by the numerous electric cars running to 

 that station. In a similar manner it has spread over a large por- 

 tion of Connecticut and into Rhode Island. It had made its 

 way up the Connecticut valley to Springfield by 1891, and to Am- 

 herst by 1895. The latter year it was found by Dr Howard at 

 Millers Falls and was reported to him then at South Vernon, it 

 having crossed the New Hampshire line. It has also been re- 

 ported from north of Salem, Mass., and at Middlebury, Vt. — two 

 localities distant from others where it has been found. 



The above record indicates most clearly that this pest has not 

 made its way to all portions of the state where it may be ex- 

 pected to thrive. The climate of the upper austral life zone 

 seems to agree with the insect, judging from the number of 

 broods and its abundance in Albany and vicinity. The area 

 within the state embraced by this zone has been represented on 

 plate 4, in the lltli Report on the insects of New York. Briefly, 

 it embraces Long and Staten islands, the valley of the Hudson 

 river north about to Saratoga and a large portion of the north- 

 western and central part of the state adjacent to the great lakes 

 and including Oneida, Cayuga, Seneca lakes and neighboring 

 bodies of water. This insect will probably make its way along 

 the lines of travel to most of the cities and larger villages lying 

 within the above limits. The beetle having become established 

 at localities not yet included within this zone, indicates that it 

 may have an even wider range, although climatic conditions will 

 probably prevent its becoming destructive. 



a Unfortunately most of these dates indicate ouly the time when the ravages of the insect 

 were serious enough to attract the attention of some one, and so otly approximately the 

 year of its arrival.
