THE CORN LEAF-TIER, LEREMA ACCIUS S. & A.* 
GEO. G. AINSLIE, 
Entomological Assistant, Cereal and Forage Insect Investigations, Bureau 
of Entomology. 
The corn leaf-tier, Lerema accius S. & A., is one of a large 
number of corn feeding species of insects which have never been 
known to cause appreciable damage, but are still a potential pest 
of this plant and of other economic grasses. It belongs to the 
Hesperidae or skipper butterflies, several of which, in the South 
are recognized as pests, among them the Bean Leaf Folder 
(Eudamus proteus L.), and the Larger Canna Leaf Roller (Cal- 
podes ethlius Cramer). 
The original description of the adult was published in a paper 
on the “‘Lepidopterous Insects of Georgia” by Smith and Abbott 
in 1797 under the name of Papilio accius. In 1872 Mr. S. H. 
Scudder erected the genus Lerema with this species as the geno- 
type. The most complete account so far published is one by this 
same author in his “Butterflies of New England” in 1889. The 
records of the Bureau of Entomology regarding this species are 
very meager. Mr. R. A. Vickery reported finding a single small 
larva on corn at Brownsville, Texas, Mr. W. R. McConnell noted 
it at several points in Mississippi, and Mr. W. H. Larrimer 
found larvae on two species of grasses at Chickasha, Oklahoma. 
The above records, a few other scattered observations and a 
series of rearings at Lakeland, Florida, during the winter and 
spring of 1913 furnish the material for the following paper. 
It is impossible to fix definite limits for the range of this 
species. It was first described from Georgia, the exact local- 
ity not being indicated. An attached note adds that “It is also 
found in Virginia.” Scudder’s map of its distribution shows it
