1923 ] Notes on the Cape Cod Brood of Periodical Cicada 205 
Town of Yarmouth.— WY loIq town except a strip about one 
to one and a half miles wide along Cape Cod Bay. 
The heaviest infestations were in the Plymouth Pine Hills 
central and southern part of Bourne, northern, central and 
eastern Falmouth, Mashpee, southern Barnstable, central 
Sandwich and central Yarmouth. 
Individual, lone specimens were taken at East Wareham, 
Ellisville (southeastern Plymouth), Woods Hole, Harwich, and 
Carver indicating, possibly, the former existence of parts of this 
brood in those sections. Fishermen from Woods Hole said that 
Cicadas could frequently be found floating in the ocean south of 
the Falmouth shore. I obtained no record of any on the Islands. 
(Nantucket or Marthas Vineyard). 
Older inhabitants of the village of East Wareham tell me 
that they remember two broods previously when the insect was 
abundant in the village. 
Mr. Lumbert of Monument Beach called my attention to a 
“big green beetle’’ which was preying on adult Cicadas and I 
asked him to collect some for me if he found more. This he did, 
and I found that it was the Calosoma beetle, C. sycophanta L. 
Later, in company with Prof. W. H. Sawyer, of the Department 
of Biology, Bates College, I took several Calosomas in the act 
of capturing Cicadas. 
The order of emergence for this brood, as nearly as I can 
make out, is as follows: 1st week in June at Bourne; 2nd week 
in June at Falmouth, Mashpee, Sandwich, Yarmouth, 
Barnstable, and Plymouth (south of village); 3rd week in June 
at Plymouth (north of Great Herring Pond). 
In driving through the infested territories south and east 
of the Cape Cod Canal, on July 11th, I found that by far the 
greatest damage done by this brood of T. septendecim L. occurs 
in the eastern part of the town of Falmouth, around the village 
of Waquoit. Here the insect has deposited its eggs in practically 
every suitable plant, including ferns, false indigo and goldenrod. 
Almost every oak from one to twenty feet high has dead and 
dying twigs hanging from it in abundance. In several cases I 
saw oaks twelve feet high and three or four inches through at 
the base with foliage entirely brown, and much of the youngest
