CHRONOLOGICAL ACCOUNT OF DIFFERENT BROOD 
brood referred to in Brood V, ;oi<l which there is every reason to believe i> thi 
recorded by Morton in lii^ "Memorial," a^ occorring in 1633. 
Dr. Fitch, in the account of hit* third brood (Now Fork Report, I. 
u Tin- third brood appears t<> have tin- most extensive geographical range. From the 
southeastern part of Massachusetts it extends across Long Island and along tl 
lantic coast to Chesapeake Bay, and up the Snsqnehanna at lea-- irlisle 
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 tribal 
west, into the Indian Territory. This brood has appeared the- present year, 1855, and 
I have received specimens from 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 bepttmdecim Brood VIII, with the great trait rim Brood XVIII, for it so happened 
that they both occurred simultaneously in l-.">.">. but the exact dividing line of 
two broods is not so easily ascertained. Certainly, after reaching the Ohio Fiver, 
the septendecim brood extends beyond Gallipolis, Ohio, for Professor Fotter. in his 
"Notes on the Cicada decern septima." records their appearance at that place in 
1821 : and Dr. Smith records their appearance at Frankfort, Lexington, and Flem- 
ingsbnrg, Ky.. in 1838 and 1855. But I strongly incline to believe that well nigh the 
f the territory mentioned by Dr. Fitch was occupied by the trededm brood, the 
reasons for which belief will he found in the account of Brood XVIII. 
Cicada- also appeared in Buncombe and McDowell Counties, North Carolina, in 
1855, but until they appear there again it wili be impossible to say. positively, 
whether they belong to this septendecim Brood VIII. or to the trededm Brood XVIII. 
1872. — The reports I was able to obtain tor 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. Xat.. VII, p. 536), 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. 187.'). from Mr. W. C. Fish. Fast 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 1" 
ties where there were no large trees they completely riddled the huck- 
leberry bushes. Between here ami Sandwich there is a continuous tract 
of woodland. Sandwich is 15 miles north of us. This tract of wood- 
land extends through a huge 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 
through the towns of Barnstable and Yarmouth. I do not know 
whether the brood extends further east down the Cape or not. It seems 
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 1S7L*. on Long Island, 
set-ins to bo confirmed, as Mr. S. S. bathvon wrote us (duly L6, 1872) that
