THE STATE ENTOMOLOGIST. 41 



(N. Y. Semi-Weekly Tribune, June 27). He also witnessed them in 

 the same place in 1S55, and as will be seen by referring to Brood 

 XVIII, they also occurred on Long Island and in southeastern Massa- 

 chusetts in that same year, 1S55. Exactly 13 years intervening be- 

 tween 1855 and 1868, one mieht be led to suppose that they had. a 

 tredecim brood in the East. But did such a brood exist, it would cer- 

 tainly have been discovered ere this, in such old settled parts of the 

 country, and all the records go to show that they have nothing but 

 septemdecim there. By referring to Brood VIII, the mystery is readily 

 solved, for we find that in that part of the country there are two sej)- 

 temdecim broods — the one having last appeared in 1855 — the other 

 the present year, 1863. 



In Ohio, this brood occurred more or less throughout the whole 

 western portion of the State, for our correspondents record them as 

 having appeared in 1868 in Lucas and Hamilton and several interven- 

 ing counties. Mr. F. 0. Hill, of Yellow Springs, in Green county, 

 Southwest Ohio, has witnessed their appearance in 1834, 1851 and 1868, 

 and they occurred in the northwestern part of the State during the 

 three same years; while the correspondent to the Department of Ag- 

 riculture, from Toledo, Northwest Ohio (July, 1868, Monthly Rep.), says 

 it is their 9th recorded visit there. Dr. Smith records it as occurring 

 around Cincinnati, in Franklin, Columbiana, Pike and Miami coun- 

 ties. 



In Indiana, there is reliable evidence of their appearance, in 1868, 

 in the southern part of the State, in Tippecanoe, Delaware, Vigo, 

 Switzerland, Hendricks, Marion, Dearborn, Wayne, Floyd, Jefferson 

 and Richmond counties. The evidence seems to show that, as in Ohio, 

 throughout the State, they belong to this septemdecim Brood XXII, 

 for Mr. F. Guy, of Sulphur Springs, Mo., has personally informed me 

 that they were in Southern Indiana in 1851, and even in Tippecanoe 

 county, on the Wabash river, where, from their proximity to Brood 

 XVIII, one might have inferred them to be tredecim, they are recorded 

 as appearing in 1834 and '51. 



In Kentucky they appeared around Louisville. In Pennsylvania, 

 Maryland, Delaware and Virginia, the territory occupied by this brood 

 is thus described by Dr. Smith : " Beginning at Germantown, Pa., to 

 the middle of Delaware ; west through the east shore of Maryland to 

 the upper part of Ann Arundel county; thence through the District 

 of Columbia to Loudon, West Virginia, where it J8W laps over the 

 South Virginia district (see Brood XII) from the Potomac to Loudon 

 county, some 10 or 12 miles in width, and in this strip of territory Ci- 

 cadas appear every 8th and 9th year. Thence the line extends 

 through the north counties of Virginia and Maryland to the Savage 

 mountains, and thence along the south tier of counties in Pennsyl- 

 vania, to Germantown." 



From the above synoptical view it results that there will, during 

 the next IT years, be broods of the Periodical Cicada somewhere or
