THE LARGER CANNA LEAF-ROLLER. 



although it inhabits also the extreme Southern States of our Union. 

 So far as can be learned it is known to exist permanently only in 

 the Gulf States, South Carolina, and Porto Rico in our domains. It 

 also inhabits Cuba and Jamaica, however, and in South America 

 occurs as far south as Argentina, where it was years ago reported to 

 be common by Burmeister. 



In an earlier article on this species (loc. cit.), Scudder's dictum was 

 followed and the mentioned occurrence of this species at Bay Ridge, 

 Long Island, and at New York City were considered as merely tran'

 These conditions have been mentioned. It is hardly probable that

 ber of 1011, as also throughout Long Island to Riverhead, but there 

 was no evidence whatever of the presence of this species in the State 

 of New York that vear.
