FOOD ■ PLANT CATALOGUE OF THE APHIDAE OF 

 THE WORLD. 



PART I * 



(A Bibliographical Appendix to Aphid Pests of Maine.) 



Edith M. Patch. 



This catalogue aims to be a host plant bibliography rather than an 

 Aphid bibliography. It maintains a systematic sequence of the families 

 of host plants, but it is neither systematic nor critical from the aphid 

 standpoint. It does not reflect the opinion of the compiler as to the 

 validity of any aphid species ; it merely selects such references as 

 appealed to her as initially desiraible in case a given species is to be 

 worked up systematically or monographically. By "initiall}! desirable" 

 is not necessarily meant the best descriptions. In many cases it includes 

 references to these ; in many, however, it includes references to appar- 

 ent contradictions and confused situations. 



The synonomies given are those recorded by the publication quoted 

 whether written in 1912 or one hundred years ago, but no attempt has 

 been made to give the complete synomony and the original sources must 

 be consulted for this. It would be a mistake for any one to expect 

 more of this List than a record of what species of aphid have been 

 reported on each species of plant with reference to the authority for 

 the statement, — -for that is all the List aims to do. Whether either the 

 aphid or the plant is correctly determined or not has been no concern 

 of the compiler. For it is the purpose of the catalogue to reflect the 

 recorded condition of things, to show up the confusion and involved 

 synonymy, and to expose the tangle which must be left to the mono- 

 graphing systematist to clear up.
