RANGE OF BROODS IN ORDER OF FUTURE APPEARANCES. 37 
Brood l.Sepiendecim—1903. (Fig.9.) 
This is a small brood, limited for the most part to the valley of the 
Connecticut Kiver in the States of Massachusetts and Connecticut, 
with one colony in the vicinity of Fall Kiver separated from the main 
swarm. It is Brood I of Walsh-Riley, and Brood So. 9 of Dr. Fitch, 
who reports it as having occurred in 1818 and 1836. It was recorded 
also by Dr. Smith from 1767 to 1852, and the genuineness of the brood 
was fully established in 1869. 
The distribution, by States and counties, is as follows: 
Connecticut. — Hartford. 
Massachusetts. — Bristol, Franklin, Hampshire. 
Brood V. — Septendecim — 1905. (Fig. 10.) 
This very compact brood, described by Fitch as Brood Xo. 6 and by 
Walsh-Kiley as Brood 111, covers in large part a prairie region extend-

ing over portions of several of the States of the Upper Mississippi 
Valley. A detached brood was formerly known in Pennsylvania, but 
seems not to have been verified in later years. 
t As the periodical Cicada is limited to forest areas, the broods occur- 
ring in prairie districts are necessarily much broken and scattered, and 
this is true of Brood V, which occurs for the most part in small colonics 
in the woods bordering streams. 
The distribution as given below is based on the localities listed in 
insect Life, Vol. 1, p. 31, with such additions and corrections as the 
last occurrence of the brood in 188S made necessary.
