to locate colonies it seemed probable that brood xi had 
become extinct. 
On June 16, 1937, Dr. W. E. Britton informed Dr. Dow 
that the writer had reported the emergence of the periodical 
cicada in East Willington, Connecticut. Dr. Dow visited 
the colony with the writer on June 20, and reported his 
observations in the Bulletin, July, 1937. The writer pre- 
pared a short article for the 37th Report of the Connecticut 
State Entomologist, Bui. 408, May, 1938. 
From the records available it seemed probable that the 
East Willington colony was the last in existence of brood 
xi. So it was with great interest that I made several visits 
in 1954 to the site of the 1937 colony on the farm of Mrs. 
Mary Blahusiak. The area has remained in pasture and 
there appears to have been no great change in conditions, 
although it has been kept partially free of brush by the 
feeding of the pastured animals. 
The first cicadas were found on June 10, 1954, in the 
same pasture area as observed in 1937. Several later visits 
were made until the cicadas disappeared. At no time did 
their numbers approach those of 1937. From casual ob- 
servations it seems that the colony has been greatly reduced 
in individuals, although it extended over about the same 
area as in 1937. 
During a visit later in the summer no evidence of egg 
laying or of subsequent wilting of twigs was found. This 
was quite surprising since the injured twigs caused by 
egg punctures were so very conspicuous in 1937. These 
observations lead to the conclusion that brood xi is ap- 
proaching extinction and one wonders how many more 
times this remarkable species will make its reappearance 
in East Willington, Connecticut.
