138 THE PERIODICAL CICADA. 
Note. — Following up the egg transferences above described and also 
discussed on pages 1G and 17 of this bulletin, letters were sent to the 
various persons named who had been charged with the planting of 
the eggs of the two broods, requesting that a careful watch be kept the 
present season and any results reported to this office. 
Of the eggs of the 13-year Brood VIE distributed in the north, reports 
were received from three localities. Professor Comstock reports of the 
material sent to Ithaca, X. Y., that he could find no indication of the 
emergence of the Cicada nor could he find any evidence of the larvae in 
the soil by digging. A similar report comes from Mr. E. P. Felt relat- 
ing to the planting made by Dr. Lintner near Albany, N. Y. Prof. 
Herbert Osborn found no trace of the insect at Ames, Iowa, the two 
localities being close to his house so that he could examine them at 
frequent intervals. No report was received from Mr. Samuel Henshaw 
of the plantings made in Essex County, Mass. 
Of the eggs of the 17-year Brood XXII sent to various southern local- 
ities, reports were received from two only, although a report is promised 
from a third. Prof. G-. W. Herrick, writing of the planting made by 
Dr. Phares on the grounds of the Agricultural and Mechanical College 
of Mississippi, says that the two trees about which the eggs were dis- 
tributed have been removed, root and branch, and the likelihood of the 
survival of the insect is very small. 
The only positive report so far received from all the plantings of eggs 
comes from Prof. Eugene A. Smith, University of Alabama, who found 
one pupal shell and noticed several holes in the ground which answer 
to the description of the exit openings made by the Cicada. The pupal 
shell was sent to me and proves to belong to the periodical Cicada. 
That it comes from the egg planted in 1885 seems probable from the 
fact that no brood is due in this locality the present year. This is a 
most interesting report because it seems to indicate that the 17-year 
period may be greatly abbreviated in a warmer latitude. It will be 
noted that part of the eggs sent to Professor Smith came from Indiana 
and the rest from Michigan. In view of the remarkable regularity of 
the periods evidenced by the large broods of the Cicada, it is rather 
unwise to give too much importance to an isolated experience such as 
described, and during the next four years a careful watch should be 
kept for the appearance of adults which may emerge each year up to 
the end of the regular 17-year period for the brood. This report makes 
it all the more important to follow the egg plantings, both north and 
south, very carefully during the next three or four years.
