lORTY-FIFTH REPORT ON THE StATE MuSEVM. 



increase and injuries as observed by bim, in tbe city of Brooklyn, 

 N. Y.: 



The Pulvinaria innumerabllis is not only destroying all of tbe soft 

 maples, Acer riibrum, and wbite or silver-leaved raaple, Acer dasy- 

 carpum, in tbe city of Brooklyn, but it bas also invaded tbe gardens 



and is rapidly destroy- 

 ing tbe grapevines, 

 and tbe Japan ivy, 

 Am2)elopsis Vetchii, 

 wbicb covers tbe 

 brick walls of many 

 tine residences and 

 cburcbes. On tbe 

 latter tbe pest bas a 

 most excellent retreat 

 and sbelter, and can 

 not be dislodged by 

 ordinary remedies. 

 Tbere are already 

 many thousands of 

 trees dying from tbe 

 attack of tbis sucking 

 peht, and tbe city is 

 doing nothing to 

 check it. A few 

 thousands of dollars 

 properly expended a 

 few years ago might 

 have saved tbe trees, 



Fig. 30.— The maple-tree scale insect, Pulvinaria iNNUMERABiLis. 1^ nrwi million of 



dollars would not replace tbe damaged trees. I have written several 

 articles calling the attention of tbe residents of Brooklyn to this pest, 

 and made one report to tbe Board of Parks (by request) on tbe same, 

 but the owners of tine shade trees groan over their loss but make no 

 practical eifort to repair it. 



Tbe future entomologist is likely to have quite as much to do as 

 those of the present day, and it is to be hoped that bis labors will be 

 more highly appreciated. 



Tbe scale of the insect with tbe large, white, cottony mass thrown 

 out from beneath it for tbe protection of the eggs and tbe newly- 

 batched young is represented in Figure 30. 



Mr. E. P. Van Duzee, of Buffalo, N. Y,, in a letter dated February 

 28th, 1891, has written of tbe large numbers of this insect observed by 

 him, after tbe falling of tbe loaves the preceding autumn, on tbe 

 maples planted as shade trees along the streets of Buffalo. He was 

 apprehensive that, in their increase, they would prove to be a great 

 scourge tbe following summer.
