Agrilus ruficollis (Fabr.). 



The Gouty- Gall Beetle. 



(Ord. CoLEOPrERA: Fam. Buprestid^e.) 



A severe attack of this insect — known by the name above given 



from the peculiar swelling in the cane that its larva produces, and also 



as the "red-necked Agrilus," from its 



copper-colored thorax contrasting with 



the brownish-black wing-covers — was 



reported by Mr. E. Winne, of Delmar, 



Albany county, N. Y., in the early part 



of May. He was growing raspberries 



extensively, and the injuries of this 



insect threatened the destruction of the

of the canes were brought to me, in which the pupae were found at 

 the time. Several of the beetles subsequently emerged, but they were 

 dead when discovered some weeks thereafter. 



A serious attack of the same insect was also brought to my notice in 

 April by Mr. M. Brooks, of Athens, N. Y. 



Remedy. 



These gentlemen were informed that the injury from this insect 

 could be, to a large extent, if not entirely, arrested, by cutting off all 

 the canes below the " gouty-gall " produced by the burrowing of the 

 larva in the wood, and burning them, in the early spring before the 

 beetle could mature and escape and deposit eggs for the continuance of 

 the attack. 



Operations of the Insect. 

 According to Walsh-Riley, the beetle makes its appearance early in 

 the summer, but sometimes as late as the fore part of July, and deposits
