In New England the Periodical Cicada {Tihircit scptnidfrlm) of l!)0(i, known 
as brood Mil (Marlatt) is confined to ])ortions of Plymouth and Harnstable counties, 
Massacliusetts. 1 have attcni])tcd to find out, as nearly as possible, the area occupied 
by tliis insect in the two counties, d he most nortliern locality seems to be tlie 
i\lanomet Hills, or “Pine Hills” as they are locally called, about five miles soutla-ast 
of Plymouth. This is the only recoial 1 have from Plymouth county. In Barnstable 
county, it is more widely distributed. IMr. Arthur Heald, Supt. of Public Schools, 
of Warcham, in a letter dated .June 27, says: — “,\t pre.sent all that I can speak of 
with certainty are the towns of Sandwich, i\la.sh|)ce. Bourne and Falmouth. Mr. 
.Io.sc])h A. Cushman found them very abundant at Xorth Falmouth, .June bu; they 
were also very ])lentiful at Cataumet and Pocasset. Miss Delia 1. firiffin. Curator 
of the Fairbanks Mu,seum, St. .lolmsbury, Vermont, found it in great numbers in the 
woods near ()sterville; this is the most easterly locality from which it has been re- 
ported. It made its appearance during the first week in .June, the third being the 
first positive date I have of its emergence.
