CHRONOLOGICAL ACCOUNT OF DIFFERENT BBOOl 29 
"New York Weekly Tribune June 24, 1876, and at the same (time Rent 
me a t* j \\ specimens. 
In the American Entomologist, vol. III. ]>. 77, the late Mr. V. T. Cham- 
bers stated that he fonnd the Cicada in Cheyenne Canon, Colo., in June, 
1876, and tin's statement very probably indicates a detached outpos 
this seventeen-year brood XI, since, as I have already said, it is not 
probable that northern and central Colorado possess a seventeen-year 
brood. 
Brood XII. — Septendecxm — 1-77. - 
In the year 1^77. and at intervals of 17 years thereafter, they will, in all prob- 
ability, appear in the vicinity of Schuylerville and Fort Miller, in New York; thence 
along both sides of the Hudson to its mouth, where They extend, at least, to New 
Haven, in Connecticut, and west across the north part of New Jersey and into Penn- 
sylvania: also iu Dearborn Connty. Indiana: Kalamazoo, Mich.: in Pennsylvania, 
North Carolina, Virginia, and Maryland. 
This brood is recorded by Professor Potter as having occurred at North Haven. Conn., 
in 1724. 1741. 1758, 17'J-J, 1809, and 1826. It was also recorded by the same writer as 
having occurred in 1826 in Middlesex County, New Jersey, and by Dr. Fitch as having 
occurred in 1-4:5 throughout the whole country mentioned above. In 18 -0, again, it 
was spoken of in the old series of the Prairie Farmer (vol. 22, p. 119) as having occurred 
that year in New Jersey, and Dr. Smith records it throughout the whole State in 
177."). 1792, 1809, 1826, and 1-4:!. Mr. James Angus, of West Farms, Westchester County, 
New York, has himself witnessed its recurrence in the years 1843 and 1860. 
In Pennsylvania. Mr. Rath von found a few individuals in 1860, and Dr. Smith - 
it extends from the Susquehanna to the Delaware River, bounded by Peter's Mount- 
ain on the south. In Virginia it occurred from the south part of London Comity to 
the Roanoke River, and from the Bine Ridge to the Potomac in 1826, 1843, and L6 
in Maryland from Anne Arundel Connty to tbe north part of Saint Mars 's, and from the 
Potomac to Chesapeake Hay, in 1809, 1826, 1843, and 1860; in Rockingham. S1 
Guilforc, Rowan, Surry, and adjacent counties, North Carolina, in 179SJ, 1809, 1826, and 
1843; in Dearborn County. Indiana, in 1843 and in 1860; and in Kalamazoo. Mich., 
during tin- same years. 
1877. — This is one of the best recorded broods: and as it appears in 
the immediate vicinity of New York. Brooklyn, Jersey City, and other 
great centers of population, tbe records for the year 1877 are abun- 
dant in newspaper articles as well as in letters from correspondents. 
The reports from New York State agree that in 1S77 the Cicadas were 
extremely abundant on Stateu Island, much less so on Long Island, 
while there were none within the city of New York. 
Along both sides of the Hudson River they were observed at many 
points, reaching- so far north as in the vicinity of Troy in Rensselaer 
County, thus exactly confirming the extent of the brood as given above. 
In Connecticut they were observed by Mr. William II. Patton, who 
wrote me as follows on July 3, 1S77 : " May 12th, large numbers of pupae 
were found under stones in woods near Meriden. Conn.: May 27th, I saw 
the first perfect insect here in New Haven, and can find no knowledge 
of its earlier appearance, although I heard rumors of its appearance 
before that date. At the present writing they are still plentiful in the 
limited localities which they frequent."
