THE TWO BROODS OF PERIODICAL CICADA SCHEDULED TO APPEAR IN 1935 
Brood IX of the periodical Cicada will appear in 1935* This is a 
well defined "brood in southern West Virginia, western Virginia, end extreme 
northwestern North Carolina, with scattered records throughout the remainder 
of West Virginia and eastward into northern Virginia and Maryland. Even 
less positive records of single year's appearances of this "brood have "been 
made for northern Ohio, southwestern Michigan, and northern Indiana,, and 
Mart lis' 6 Vineyard, Mass. The last was onlv recorded in 1833- 
The unsubstantiated theory of acceleration or- retardation of certain 
individuals of any given "brood might account for some of these scattered 
records. This "brood was first recorded in 1833 an< ^ kas been recorded at 
every subsequent period of abearance. A. D, Hopkins, "by a survey carried 
on in 1901, did most to delimit the range of this interesting "brood which 
nearly exactly fills the gat) "between the three foci of brood X, the largest 
brood of the 17 year race due to appear in 1336. 
Following is a list of all the records available to the Insect Pest 
Survey on the occurrence of this brood. Under each State the counties
