Six broods are known to occur in New York State, the one appear- 
ing the present season being designated by Dr Marlatt as brood 8. 
It is the one known as number 6 of Messrs Walsh and Riley, and 
was confused by Dr Fitch in 1855 with a 13 year brood, which 
occurs to the south. This species has been recorded from two coun- 
ties in Massachusetts, it is listed from Long Island and occurs in 
several places in northern New Jersey and in central Pennsylvania. 
No detailed records, so far as we have been able to find, have been 
made of the occurrence of this brood in New York State, and this 
opportunity 1s taken to place on record certain facts concerning 1ts 
distribution, which have been ascertained during the past summer. 
This brood appears to be limited very largely to a section of 
Suffolk county west of Riverhead and occurring, so far as we know, 
in a very few localities in the eastern part of Queens county> The 
list of localities compiled from various correspondents is as follows: 
Wading River, Port Jefferson, Saint James, Farmingville, Coram, 
on the road from Port Jefferson to Patchogue, Manorville, East- 
port, East Moriches, Center Moriches, Commack, Brentwood, Cold 
Spring Harbor, Laurelton, Huntington, Oyster Bay, East Norwich 
and Syosset. There is also a record of its presence in very limited 
numbers on Staten Island. 
There is a bare possibility that this brood also exists in the 
Hudson river valley, though we are inclined to believe that the 
record given below is based upon a mistaken identity in the species 
or else that they may refer to stragglers from brood 12, due to 
appear next in 1911. Mr H. D. Lewis of Annandale, N. Y. who 
resides in one of the strongholds of this latter brood, states that this 
summer he observed several pupal cases, which he is quite confident 
are those of the periodical cicada, though we would not be surprised 
if he had mistaken therefor those of the harvest fly, Tibicen 
tibicen  Linn., an insect which appears later in the season and 
at the time when the pupal cases were observed by Mr Lewis. 
This species is such a unique form among insects that consider- 
able interest has been aroused in regard to the possibility of its 
eventually being exterminated with the advance of civilization. The 
somewhat detailed records as to the abundance of this species in 
the various localities mentioned above, may- prove of some service 
in determining this question in later years. The Brooklyn Daily 
Times of June 29 stated that periodical cicadas were present in 
large numbers at Wading River in the woodlands to the north of 
the Long Island Railroad experimental farm. The same paper,
