 Ainslie. 3 



The fact that D. saccharalis crambidoides has been found to be limited 

 to such widely separated areas as southern Florida, southern Louisiana, 

 and the southern tip of Texas will no doubt occasion some surprise. The 

 explanation is that there is strong evidence tending to prove that the 

 species was brought to this country in shipments of sugar cane from the 

 Tropics and that it became established in the three sections in which 

 sugar cane is an important crop. Both forms of larvae of the two species 

 are well shown in Plate LXXXIX.
