Observations showed that the red- 

 headed flea beetle, Systena fron- 

 talis Fab., was somewhat abundant 

 in Sheridan vineyards July 21 and 

 relatively much more so than in and 

 about Westfield, where most of our 

 experimental work was done. 



Food plants. This beetle has a comparatively restricted food 

 habit. It was early observed by Mr Walsh on grapevines, and 

 the late Professor Riley recorded its feeding on the American 

 redbud, Cercis canadensis. It is also known to feed 

 on the native Virginia creeper, Ampelopsis quinque- 

 f olia. 



Varieties affected. The Concord, as is well known, is almost 

 universally grown in the Chautauqua region, and consequently is 

 one that has suffered to the greatest extent from injuries by this 

 pest, though our observations convince us that the Niagara is 

 even more liable to injury, and in the cases we have seen the 

 difference was quite marked. Referring to Ohio reports, it will 

 be seen that Mr Maxwell states that Wordens and Brightons were 

 killed first, while Concords and Catawbas were not so badly in-
