CHRONOLOGICAL ACCOUNT OF DIFFERENT BROODS. 43 
In Ohio, the brood occurred more or less throughout the whole; western portion of 
the State, for our correspondents record them as haying appeared in 1866 in Lucas 
and Hamilton and several intervening counties. Mr. F. C. Hill, of Yellow Springs, in 
Greene County, southwestern Ohio, has witnessed their appearance in 1634, 1851, and 
1868, and they occurred in the northwestern part of the State during the three same 
years; while the correspondent to tin- Department of Agriculture, from Toledo, 
northwestern Ohio (July, 1868, Monthly Report), says it is their ninth recorded visit 
there. Dr. Smith records it as occurring around. Cincinnati, and in Frauklii 
lumbiana, Pike, and Miami Counties. 
In Indiana there is reliable evidence of their appearance in 1868 in the southern 
part of the State, in Tippecanoe, Delaware, Vino, Switzerland, Hendricks, Marion, 
Dearborn, Wayne, Floyd, and Jefferson Counties. Tin; evidence seems to Know that, 
as in Ohio, throughout the State, they belong to the septendecim Brood XXII, for Mr. 
F. Guy, of Sulphur Springs, Mo., has personally informed me that they were in south- 
ern Indiana in 1851, and even in Tippecanoe County, on the Wabash River, where, 
from their proximity to Brood XVIII, one might have inferred them to he Iredecim : 
they are recorded as appearing in 1834 and 1851. 
In Kentucky they appeared around Louisville. In Pennsylvania. Maryland. Dela- 
ware, and Virginia the territory occupied by this brood is thus described by Dr. Smith : 
" Beginning at Germantown, Pa., to the middle of Delaware; west through the east 
sbore of Maryland to the upper part of Anne Arnndel County : thence through ihe 
District of Columbia to Loudoun, West Virginia, where it laps over the South Virginia 
district (see Brood XII) from the Potomac to Loudoun County, some 10 or 12 miles in 
width, and in this strip of territory Cicadas appear every eighth and ninth year. 
Thence the line extends through the northern counties of Virginia and Maryland to 
the Savage Mountains, and thence along the southern tier of couuties in Pennsylvania 
to Germantown. 
Since the above was published, seventeen years ago, I have received 
reliable testimony to the effect that Dr. Fitch may, after all, be right 
in extending- this brood as far south as Georgia, as will be seen by 
referring to the notes to Brood II, and it is to be hoped that this 
year's (1885) observations may definitely settle this interesting point. 
The counties in Georgia where the appearance of the Cicada may be 
looked for this year are those of the extieme northwestern corner, and 
more especially Habersham County. 
Otherwise the notes I have since received do not alter the bounda- 
ries of this brood as given above. In 1868 the Cicadas appear to have 
been extremely numerous in the city of Germantown, Pa., as will be 
seen from the following extract from a letter we received on June (3, 
1881, from Mr. John B. Wood, of that city: •' In the year L868 my wife 
being sick nearly all summer she was very much disturbed by what we 
called 17-year locust. They seemed to come up out of the ground from 
under the pine trees, but preferred climbing up a large pear tree, going- 
out to the end of the branches and stinging the pears. They were in 
thousands, some of them roaring out and others replying to them, 
making a fearful din, which we were powerless to overcome. The 
ground around this pear tree, and a few pines covering a section of land. 
I should say 20 or 30 feet square, was fairly riddled with their holes. 
All around here they appeared in this way in spots, but tilling the air 
with their racket. They were in full blast bv the 19th of dune." The
