THE SUGAR-CANE MOTH BORER. 



11 



Dr. Dyar has determined the species from Louisiana as Diatraea 

 saccharalis cramhkloides. 



The authors' observations indicate that D. zeacolella occurs in 

 Georgia and northern Florida, as well as in the Carolinas and Vir- 

 ginia. In places in these States where both corn and sugar cane are 

 grown this species has been found to be abundant in corn while rare 

 or absent in adjoining cane fields. Practically, it may be regarded 

 as an enemy of corn exclusively. The larval characters which distin- 

 guish D. zeacolella from D. saccharalis cramhidoides have been noted 

 elsewhere by the senior writer (75) and have been further investi- 

 gated by Mr. Carl Heinrich. (See description of larva, p. 13.) 



The southern Arizona species (D. lineolata), observed by the au- 

 thors at Phoenix, Ariz., on sugar cane and Johnson grass, has the 

 distinctive habit of feeding on the leaves of cane until quite large be- 

 fore entering the stalk. 



D. saccharalis cramhidoides occurs in both corn and sugar cane in 

 the area infested by this variety. It will be noted that the observa- 

 tions of the authors, limiting the variety to southern Louisiana with 

 a small portion of Mississippi, southern Florida, and the lower Rio 

 Grande Valley in Texas, are not at variance with Dr. Dyar's gen- 

 eral statement, " Gulf States and lower Mississippi Valley." 



The following species of Diatraea are recorded from various parts 



of the world :
