Systena marginalia Illiger.

This flea-beetle is said by Mr. Harrington to abound upon the elm, 

 oak, etc., in the summer and autumn, while early in September he found 

 it in great numbers feeding on the foliage of the sweet hickory. (Rep. 

 Ent. Soc. Ontario for 1883, p. 49.) 



The beetle. — A small, long beetle of a lemon-yellow color, and having the prothorax 

 and wing-covers edged with black. The hind femora or thighs are much swollen, 

 adapting it for leaping like a flea.

Conotrachelus elegans Say. 



Order Coleoptera ; family Curculionid^. 



We have observed this weevil at Providence, busily engaged the last 

 of May, and in 1882 from June 8 to 13, laying its eggs in the partly 

 rolled-up leaves of the pig-hickory {Carya glabra), and during the 

 process cutting off the leaves, which hang down, wither, and turn 

 black. 



87. The plum weevil. 



Conotrachelus nenuphar (Herbst). 



This common weevil was noticed on the leaves of the pig hickory, 

 May 25, at Providence.
