Genus HARRISINA Packard 
Three species belonging to the genus occur within the United 
States. Two of these are indigenous to Texas and Arizona. The 
other has a wide range through the Appalachian subregion. We 
have selected it for illustration.

Syn. texana Stretch. 
The habits of this insect have been so well described by Pro¬ 
fessor C. V. Riley that we cannot do better than quote some 
passages from his account, 
which is to be found in the 
“Second Annual Report of the 
State Entomologist of Mis¬ 
souri,” at page 85. He says: 
Y During the months of July 
and August, the leaves of the 
grape-vine may often be found 
denuded of their softer parts, 
with nothing but the veins, and 
sometimes only a few of the 
larger ribs left skeleton-like, to 
tell the mischief that has been done. Very frequently only por¬ 
tions of the leaf will be thus denuded, and in that event, if we 
examine such a leaf closely, we shall find the authors of the mis¬ 
chief drawn up in line upon the yet leafy tissue with their heads 
all toward the margin, cutting away with their little jaws and 
retreating as they feed.
