Psyche 
[December 
The ‘^active pupae’ ^ were emerging until about June 22d, the 
height of the emergence apparently coming from about the 16th 
to the 19th. At this time, during the evenings, tremendous swarms 
of immature forms came out of the ground and ascended any 
upright object within range. Mr. Lumbert claimed to have 
seen several nymphs come out of a single chimney during this 
time. He also told me he had found active pupae in the spring, 
about 18 inches below the surface of the ground. The adults 
were usually all on the wing by the morning following nymphal 
emergence. 
On June 20th my attention was called to another part of 
the brood in Plymouth, between that place and Manomet on a 
ridge known locally as The Pine Hills. On the same date, I 
received reports of Cicadas infesting territory from Falmouth 
east to Osterville; and on Wing’s Neck, which is a part of Bourne 
extending westward into the waters of Buzzards Bay. On June 
21st two specimens were taken in East Wareham near the State 
Cranberry Bog. 
The area of infestation of the Cape Cod brood for 1923 
may be described as follows: 
Town of Plymouth. — From the southern end of the village 
(Plymouth proper) southeast to Manomet and west from there 
to Great South Pond; a second area around the northern end of 
Great Herring Pond. 
Town of Wareham. — Eastern corner. 
Tow 71 of Bourne. — The whole town more or less, the heaviest 
infestation occuiTing on the south side of the Cape Cod canal 
from Bourne High School eastward to Sagamore and southward 
to Bourne-Falmouth town line, and westward to within one 
mile of the Coast line of Buzzards Bay except at Wings Neck, 
where the infestation came to the water’s edge. 
Town of Falmouth. — Whole town except from Falmouth 
village to Woods Hole where only a few specimens were taken 
after full emergence had taken place to the northward. 
Town of Sandwich. — Whole town except a strip one to two 
miles wide along Cape Cod Bay. 
Town of Mashpee. — Whole town. 
Toivn of Barnstable. — Southern half of town.
