Canada, although it is an American species, and for a score of 

 years has been a serious pest in New \'()rk and other states. 



Within three or four years our Coleoptera have been 

 augmented by two European beetles which fortunate!}- arc not 

 obnoxious, but which ha\ e spread and multipHed with great 

 rapidity. Ten \ears ago Sphceridimii scaralheoides L., had 

 onl)' (jnce been recorded from Canada, but since then it has 

 rapidly increased and has become apparently fully established. 

 The late Mr. Caulfield of Montreal about 1886 sent to me 

 specimens of Apliodius prodromus Brahm. collected by him in 

 that cit\'. The beetle has now become one of our Cfjmmonest 

 species, and several introduced species of the same genus are 

 also abundant {fossor, ijiqiiiiiatiis.fimctarius. grajiarius, etc.J 



The foregoing illustrations will ha\e shown that it would 

 require a very extended list to enumerate all the additions that 

 from year to year have lieen made to the original insect life of 

 this region, so in conclusion \\ ill be stated merely two general- 

 izations which this consideration of the suliject seems to 

 establish. 



First ; that all our most attractixe insects, such a;^ the gaily- 

 painted butterflies and moths, the flashing dragon-flies in 

 " sapphire mail " and the beetles of varied shapes and colours, 

 belong to the indigenous fauna, and that, with the exception of 

 some aggressive diptera such as deer-flies, black flies and 

 mosquitoes, few of the members of that fauna have proved to be 

 very obnoxious or serious pests. 



Second ; That nearly all the connnon and destructive 

 insects, against which our farmers, fruit-growers and gardeners 

 ha\e to wage persistent and costK' warfare, ha\e been introduced 

 at various times from Europe, and that these species, through 

 the absence of the parasites and other influences which keep 

 them in check in their original habitat, often multiply with 

 startling rapidity and occasion continual and grie\ous losses to 



our communitx'.
