IDENTIFICATION OF INSECTS. 



We have below listed some of the more important inquiries 

 which have reached us regarding insects during the year. These 

 inquiries were not always accompanied by specimens, although 

 leaving no doubt in the mind of the Entomologist as to what the 

 pest under discussion was ; at other times the specimens sent 

 were so badly crushed (notably plant lice) that, although in a 

 general way it was evident from text of letters what the insect 

 was, ''Grain Plant Louse," "Plum Aphis," "Apple Aphis," etc., 

 one could not with safety give the scientific name for the genus 

 and species. The Grain Plant Louse, for instance, about which 

 many inquiries were sent in, may have been Nectarophora ccrealis 

 or A^ granaria, or something else. The desired end in all cases, 

 however, was attained by the correspondent receiving the com- 

 mon name, when not known to himself, and remedies, when rem- 

 edies were asked for. The subjoined list presents an interesting 

 calendar as to the first appearance of certain pests, their com- 

 parative abundance and their continuance through the season. 

 For instance, our first complaint of Apple Aphis ("Green Aphis") 

 came in April. It may be said in passing that severe cold 

 weather, with some snow and ice, at this time killed these early 

 hatched lice far better than any treatment man might have given.
