SEVENTEEN-YEAR
LOCUSTS TO APPEAR
Little Actual Damage Pre-
dicted

Washington, Broof of the cicada,
commonly known as the seventeen
year locust, is expected to appear
in this locality during June. This
particular brood made its last APP
pearance in this territory in 1898.
The seventeen-year locust COW
ers in its range nearly all of the
United States from the Missis-
sippi Valley eastward The cur
ious feature of its regular period
ic appearance and its long subter-
ranean life give it perhaps the
greatest popular interest which at
tacheS to any insect on this conti-
nent, and lead to many inquiries
with every temperance of any
important brood. There are two
races Of this insect: Cd the seven
teen-year race, which occurs in II
different broods over the north
ern and central United States, and
(2) the thirteen-year race, which
occurs in different broods through
out the southern states from
Texas eastward. When any of
these broOds are characterized by
great swarms they naturally cause
fears for the safety of trees. The
actual damage, however, is slight
and is accomplished by the female
cicada when she cuts the bark of
the tree in the deposition of her
eggs.
While the expected brood is not
an important one, it covers a
much wider territory than any of
the other seventeen-year broods.
According to the records, the num-
ber of locusts to be expected over
most of this territory is not great,
except in the Northwest and in
the Southeast.
A careful canvass of the whole
cicada area was made by the Bu-
reau of Entomoyogy with the as
sistance of the State entomologists
in 1898. These reports, if they
may b erelied upon, extend the
range of the periodical cicada in
Wisconsin and Michigan much
farther north than any of the old
records. The localities assigned
to this brood in North Carolina,
South Carolina, and Georgia, and
in eastern Kentucky and Tennes-
see ,are, in the main, in counties
in the elevated mountainous dis
trict, and the correctness of the
reference to this brood is estab-
liShed by earlier records as we'll
as indicated by the elevation.
The records of distribution
given below are as published in a
bulletin of the Bureau of Entomol-
ogy of this department. The
starred counties indicate the oc-
currence of the cicada in one
or more characteristic, dense
swarms; the underscored counties
are confirmation of old records,
the counties inclosed in parenthe-
sis are old records not reported in
1898, and counties followed by a
mark are doubtful records. The

ties, follows:
