A BIBLIOGRAPHY OF THE LITERATURE ON THE DESCRIBED 



TRANSFORMATIONS AND FOOD PLANTS OF NORTH 



AMERICAN SPECIES OF AGRILUS (COL.). 



BY C. A. FROST AND H. B. WEISS.* 

 New Brunswick, N. J. 



In 1900 Chittenden published a paper on the "Food Plants and Injury of 

 North American Species of Agrilus/'i in which 31 species were listed together 

 with notes on food plants and injury. Since this paper, nothing of a similar 

 nature has appeared, and during the period between 1900 and 1920 new species 

 have been described and much additional biologic information on several 

 economic species has accumulated The present paper, therefore, brings to- 

 gether to date all of the references to the literature on the life-histories, habits 

 and food plants of those of our North American species about which such in- 

 formation is known, supplemented by very brief notes on the important economic 

 ones. 



The habits of such species as viitaticollis Rand., hilineatus Web., anxius 

 Gory, ruficollis Fab., and sinuakis Oliv., appear to be fairly well known, due 

 undoubtedly to their activities as enemies of cultivated and forest trees and 

 plants which necessitated studies. The habits of many other members of this 

 extensive genus are less completely known and of a large number nothing what- 

 ever concerning food plants, etc., appears to have been recorded. In the list 

 which follows, references to the places of original description and geographical 

 distribution have been omitted as such information can be found in Leng's 

 "List of the Coleoptera of North America."
