the month of June, and it may not be uninteresting in view of the fact, 
to give a short account of the species in connection with this locality. 
It must be borne in mind that while Cicada septendecim Linn. appears 
at intervals of seventeen years, its advent is not in the same year in 
all of the middle states, or in all the counties of this State, but that 
there are separate broods or colonies, that emerge in great numbers in 
districts of varying extent, the limits of which are not sharp or well 
defined. Thus it happens that while there is a certain brood that 
appears periodically on our island, and attracts at such times general 
attention, there are also other years when the Cicada occurs in small 
numbers. At such times it will often be found that a brood is emerg- 
ing not many miles away, and that the island lies within the outer 
margin of the territory. 
This matter of distribution and much more regarding the seventeen 
year Cicada, and the more southern thirteen year form, has been 
recorded by Professor Riley in Bulletin No. 8 of the U. S. Depart- 
ment of Agriculture, Division of Entomology. Professor J. A. Lint- 
ner, New York State Entomologist, also gives, in his second annual 
report, the distribution of the Cicada in this State, noting five broods 
as occurring within its limits. ! 
In 1826 this Cicada appeared in great numbers on the island, as I 
have been informed by my grandmother ; in 1843 they came again, 
a recorded by Thoreau, and still again in 1860 and in 1877. In the 
latter year I saw many tree trunks and fences brown with their cast 
pupa skins, and the whir of their flight and monotonous song, could be 
eard in every direction. Dr. Fitch, in 1855, wrote of the seventeen 
year Cicada and records this brood as inhabiting the valley of the 
Hudson River. Since his time, the various broods in different parts of 
the country, have been numbered for convenience, and the one inhab- 
an the valley of the Hudson and Staten Island, is known as No. 
During the visitation of 1877, I noticed that many of the Cicadas 
me affected by the singular fungus Massospora cieadina Peck. Men 
the insects were alive and walking about the fences and the ue trunks, 
if the abdomens of the infected individuals were suddenly jarred, they 
gave forth a cloud of innumerable spores. It has been stated that 
Y injured specimens are attacked by this fangus, n d 
toward the latter part of the season. 
Since 1877, the seventeen year Cicada has not appeared on tar 
d in great numbers, and probably but few have been noti 
: “xcept by those who have looked for them. The facts connected with
