THE SUGAR-CANE MOTH BORER. 
11 
Dr. Dyar has determined the species from Louisiana as Diatraea 
saccharalis crambidoides. 
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 crambidoides 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 crambidoides 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 Bio 
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 :
