This insect, although quite abundant at times in certain localities, 



had not occurred in the collections made by me in Albany and Schoharie 



-counties, or in occasional collecting in other portions of the State. From 



the abundance with which it is reported below, upon the locust, it may 



have been overlooked by me in my limited examinations of the insect 



fauna of that food-plant. Dr. Fitch, writing in 1858, stated that he had 



never met with it in the eastern part of the State, although common in 



the southern. 



The Insect on Long Island. 



Examples were received by me on August 31, from Dr. Harrison G. 

 Dyar, which had just been taken by him from locust trees {Robinia') at 

 Yaphank, L. I. The leaves had been eaten (PI. VIII, fig. 2) until they 

 bore the appearance of elm leaves attacked by the elm-leaf beetle, and 

 as the result of the severe injury, the foliage was rapidly falling. 



In a re-examination of the trees by Dr. Dyar a week later — a road- 

 side row of about twenty in number and patches of locust shrubs in a 

 woods opposite — all the remaining foliage had turned brown. To the 

 east and the west of this locality only a slight injury was noticeable, while 

 to the northward, in another row of locusts between two fiekls, the leaves 

 were still green and apparently uninjured. 



In West Virginia. 

 Dr. A. D. Hopkins has written on the abundance and injuries of this 

 Chrysomelid as observed by him in 1890, at Morgantown, W. Va., and 

 its vicinity. In his bulletin on "Insect Ravages — Yellow Locust" 

 \sup. cit.), he has stated as follows : 



" This beetle was extremely plentiful on the locust leaves at the time 

 the investigation was being made (early August), — as many as eight or
