THE SENENTEEN-YEAR LOCUSTS
Government Sends Out Warming
Have Appeared in OConcc.

monty known as the l7-ycar locuSt
is expected to appear in May and
June this year in scattered localities
covering much OF the Northern and
Central States lying between the
hudson and Mississippi rivers, OK
tending along she Appalachian Gle
vatCd plateau into NorthCrn Georgia
and South Carolina. This particular
brood made its Last appearance in
this territory in 1898.
The l7-ycar locust covers in its
range nearly all of the United States
from thc Mississippi Valley eastward.
Tn" curious feature Of its regular pc
riOdir appearances and its long sub
tcrrHmcpn life give it perhaps the
greatest popular interest which at
tarhes to any insect on this conti-
neat, and lead to many inquiries with
every rcappcarancN Of any important
insect: CD the ~ year race, which
occurs in | I different brOods over the
northern and central United States,
and (2) the l2-yrar race, which Oc-
ours in different hroods throughout
the Southern States from Texas east
ward. When any Of these broodS are
characterized by great SwarmS they
naturally cause fears for the safety
Of trees. The actual damage, how
ever, 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, il covers a much wi
der territory than any Of the other
l7-y"ar brooda. According TO the
records, the number Of locusts to be
expected over most Of this territory
is not great, except in the Northwest
and is the Southeast.
A careful investigation Of the
whole cicada area was made by the
Bureau Of Entomology with the as
siStanCc OF the state cntomologistS
in 1898. These reports, if they may
he relied upon, extend the range Of
the periodical CiCada in Wisconsin
than any Of the Old Records. The
localities assigned to this brood in
North Carolina. South Carolina and
Georgia. and in eastern Kentucky
and Tennessee, are. in the main, in
counties in the elevated mountain
Gus district. and the correctness of
the reference to this brood is cstab-
Eshcd by earlier records as we'll as
indicated by the elevation.
Prohablo Distribution.
Tn" records OF distribution (par-
uaD given below are as published
in a bulletin OF the Bureau OF Ento-
moloGy OF this department. The
starred counties indicate the occur
renee Of the cicada in one or more
CHARACTERISTIC. dense swarms: and
counties followed by two stars are
doubtful records:

Damage and Partial Remedies.
Ordinary rcpcllrnt substances,
Sucn as kerosene emulsion or car
bolic acid solutions, seem 10 have
very little effect in prc?cnting the
oviposi,ion Of these insects. Some
recent experience. however, indi-
Gates that trees thoroughly SPRAYED
with Bordeaux mixture or lime
wash are apt to he avoided by the
cicada, especially if there are other
trees or woods in the ncighborhood
on which they can OvipOSit. The most
reliable means Of protecting nurscr-
les and young orchards is by collect
ing the insects in bags or umbrellas
from the trees in early morning or
late evening, when they are some
what torpid. Such collectiCns
should be undertaken at the fir.
appearance of the cicada and re-
peated each day.
Vigorous young trees often re-
