Brood VI is evidently a forerunner of the very large 13-year 

 Brood VII which appeared in 1898 in the Mississippi Valley. The 

 geograpical range of Brood VII was mapped out in the Annual 

 Report of this Department for 1885, and it will be seen from this 

 map that the southern limits of Brood VII almost precisely coincide 

 with the northern limits of our Brood VI. 



The following is an enumeration of the counties from which Brood 

 VI has been recorded : 



Mississippi : — Counties of Adams, Amite, Claiborne, Franklin, 

 Jefferson, and Wilkinson. 



Louisiana : — Parishes of East Baton Rouge, East Feliciana, Liv- 

 ingston, St. Helena, St. Tammany ('?), Tangipahoa (?), Washing- 

 ton (?), and West Feliciana.
