Grapevine fidia, F i cl i a v i t i c i d a Walsh. This pest has 

 become thoroughl}- established in some of the vineyards about 

 Riplej' N. Y., where it has already destroyed several and 

 is seriously injuring others. An examination of the infested

 area was still quite limited, though the beetles were known to 

 occur in small numbers over a considerable tract. Mr F. A. 

 Morehouse stated that he found the pest most injurious to those 

 vines from which the earth had been plowed away mor(» or less,

thus affording the larvae a better opportunity 1o get at the 

 roots, while those well protected by earth suffered com- 

 paratively little. This is certainly worthy of further trial; 

 and, while it can hardly be expected to afford absolute immu- 

 nity, it may decrease the injury materially. Spraying the vines 

 toward the last of June or early in July with arsenate of lead, 

 preferably using the prepared paste form now on the markets, 

 wall do considerable to lessen the damage by poisoning the
