of the large towns and more densely populated districts of the Atlantic 
seaboard. 
Fitch described its limits as his Brood No. 2, Walsh-Riley as Brood 
VIII, and Riley’ as his Brood XII. It has been reported in Con- 
necticut regularly every seventeen years since 1724, and in New 
Jersey since 1775, if not earlier, and almost equally long records of 
it in other States have been made. 
On the occasion of its last appearance, in 1894, its distribution in 
New Jersey was very carefully studied by Prof. J. B. Smith, confirm- 
ing 1ts occurrence in every county in that State, and in New York

similar studies were made by Dr. J. A. Lintner. The Bureau also 
received a vast number of reports from these and other States in 
answer to a circular prepared by Professor Riley and mailed in May, 
1894. Some of the southern records obtained in 1894 are doubtful, 
and this applies especially to the localities in North Carolina, because 
of the occurrence that year also of Brood XIX of the 13-year race. 
The distribution as listed below is based on the old records given in 
the circular cited, with such additions and corrections as the reports of 
appearance in 1894 made necessary. 
The distribution, by States and counties, is as follows: 
Connecticut.—Fairfield, Hartford, Litchfield, Middlesex, New Haven. 
Districr or CotumBrA.—Throughout.
