Of the various 13-year broods that are recorded, only two are of large 

 extent, Brood VIII (1881-1894-1907) and the present brood. Both 

 occupy the Mississippi Valley from northern Missouri and southern 

 Illinois to Louisiana, but while Brood XVIII occurs also in many other 

 localities throughout the other Southern States as far east as Virginia, 

 the present brood seems to be confined to the Mississippi Valley, with 

 the exception of a detached area in Georgia, which, however, has never 

 been confirmed beyond doubt. In the Annual Report of the U. S. 

 Department of Agriculture the geographical distribution of Brood VII 

 has been discussed and illustrated by a map. Since that year very 

 little additional information has been obtained. The only locality in 

 Indiana (Posey County) rests upon a record received in 1885 and is, in 

 all probability, not correct. There is also a vague report, received in 

 1885, of the occurrence of this brood in Saint Clair County, Alabama.
