SOME ANTS AND MYRMECOPHILOUS INSECTS FROM 



TORONTO. 



BY GEO. B. KING, LAWRENCE, MASS. 



During the summer of 1896 I received specimens of ants collected 

 by Mr. R. J. Crew, of Toronto, in exchange for such Coleoptera as I 

 could find for him in my locality. He writes me that he noticed no 

 insects with the ants other than the Coleoptera and some aphids in a 

 nest of ants, but did not capture any. 



I have found, however, upon looking them over, they contain several 

 very interesting species of various orders : some truly myrmecophilous, 

 some occasional, while others were brought into the nests by the ants, 

 to be used by them for food ; this will apply to a number of Hemiptera 

 collected by Formica snbsericea. Say. 



It may appear to some who are collecting ants'-nests Coleoptera 

 only that the finding of Agonoderns pallipes, Fabn, and Otiorhynchus 

 oratus, L., is merely occasional. The position in which these Coleoptera 

 are found with the ants here in Massachusetts, and the frequently finding 

 them with various species of ants, lead me to believe that they are more 

 than incidental or casual visitors. 



I am not familiar with the scattered literature treating upon the
