CHRONOLOGICAL ACCOUNT OF DIFFERENT BROODS. 25 
brood referred to in Brood V, and which there is every reason to believe is the one 
recorded by Morton in his ‘‘ Memorial,” as oceurring in 1633, 
Dr. Fitch, in the account of his third brood (New York Report, I, page 39), says: 
“The third brood appears to have the most extensive geographical range. From the 
southeastern part of Massachusetts it extends across Long Island and along the At- 
lantic coast to Chesapeake Bay, and up the Susquehanna at least as far as to Carlisle 
in Pennsylvania; and it probably reaches continuously west to the Ohio, for it occupies 
the valley of that river at Kanawha in [West] Virginia, and onwards to its mouth, 
and down the valley of the Mississippi probably to its mouth, and up its tributaries, 
west, into the Indian Territory. This brood has appeared the present year, 1855, and 
I have received specimens trom Long Island, from South Illinois, and the Creek Indian 
country west of Arkansas,” &c. ; 
There is every reason to believe that Dr. Fitch, in this account, has confounded 
this septendecim Brood VIII, with the great tredecim Brood XVIII, for it so happened 
that they both occurred simultaneously in 1855, but the exact dividing line of these 
two broods is not so easily ascertained. Certainly, after reaching the Ohio River, 
the septendecim brood extends beyond Gallipolis, Ohio, for Professor Potter, in his 
“Notes on the Cicada decem septima,” records their appearance at that place in 
1821; and Dr. Smith records their appearance at Frankfort, Lexington, and Flem- 
ingsburg, Ky., in 1838 and 1855. But I strongly incline to believe that well nigh the 
rest of the territory mentioned by Dr. Fitch was occupied by the tredecim brood, the 
reasous for which belief will be found in the account of Brood XVIII. 
Cicadas also appeared in Buncombe and McDowell Counties, North Carolina, in 
1855, but until they appear there again it will be impossible to say, positively, 
whether they belong to this septendecim Brood VIII, or to the tredecim Brood XVIII. 
1872.—The reports I was able to obtain for this year are as follows: 
Mr. F. G. Sanborn wrote us on January, 1873, that he could find no 
trace of the appearance of this brood in Massachusetts in 1872. Dr. 
Packard, however (Amer. Nat., VII, p. 556), says they appeared in the 
southerly part of the State. Moreover, the existence of this brood in 
southeastern Massachusetts has been fully confirmed by the following 
letter we received on January 17, 1873, from Mr. W. C. Fish, East Fal- 
mouth, Mass.: 
‘““The seventeen-year locusts were very abundant here the past sea- 
son, and did much damage in the woodlands, particularly among the 
young oak sprouts of a few years’ growth, and in some of these locali- 
ties where there were no large trees they completely riddled the huck- 
leberry bushes. Between here and Sandwich there is a continuous tract 
of woodland. Sandwich is 15 miles north of us. This tract of wood- 
land extends through a large portion of Plymouth County. I know 
that the locusts occurred through nearly all of this tract from Plymouth 
south and east through the towns of Sandwich and Falmouth, and east 
‘through the towns of Barnstable and Yarmouth. I do not know 
whether the brood extends further east down the Cape or not. [tseems 
a little singular that when it occurs in such abundance here on the shore 
of Vineyard Sound, that they should come another year on the island 
of Martha’s Vineyard so near us.” 
In New York the appearance of this brood in 1872, on Long Island, 
seems to be confirmed, as Mr. S.S. Rathvon wrote us (July 16,1872) that
