174 KANSAS CITY HE VIEW OF SCIENCE. 



on the south by the Missouri river.* The southeast part of the state, where Dr^ 

 Smith has recorded it since 1829, is most thickly occupied. I enumerate those 

 counties in which there is undoubted evidence of their appearance during the 

 present year (1868), viz.: Audrain, Bollinger, Benton, Clarke, Chariton, Calla- 

 way, Cooper, Cole, Franklin, Gasconade, Iron, Jefferson, Knox, Lewis, Marion, 

 Macon, Morgan, Moniteau, Pike, Phelps, Pulaski, Polk, Pettis, Schuyler, St. 

 Charles, St. Louis, St. Francois, St. Clair, Warren, and Washington. 



It not improbably overlaps some of the territory occupied by the septemdecim 

 Brood XIV [a brood which appeared last in 1879], but I do not think it extends 

 into Kansas. 



In Illinois it occurs more or less throughout the whole southern half of the 

 state, but more especially occupies the counties from the south part of Adams 

 county along the Mississippi to the Ohio, up the Ohio and Wabash rivers to Ed- 

 gar county, and then across the center of the state, leaving some of the central 

 counties in South Illinois unoccupied. To be more explicit, I enumerate all the 

 counties in which it undoubtedly occurred during the present year (1868) : Ad- 

 ams (south part, back of Quincy), Bond, Clinton (northwest corner, adjacent to 

 Madison), Champaign, Coles, Crawford, Cumberland, Clay, Clark, Edwards, 

 Edgarf (especially in the eastern part), Franklin, Gallatin, Hardin, Hamilton, 

 Johnson, Jasper, Jersey, Jefferson, Lawrence, McLean (east end), Macon, Madi- 

 son, Marion, Massac, Monroe, Pike, Perry, Piatt, Pope, Richland, Randolph, 

 Sangamon, Saline, St. Clair, Union (northeast corner), Washington, Wayne, Wa- 

 bash, WiUiamson, and White. There were none the present year, either at De- 

 catur, in Macon county, or at Pana, in Christian county; nor were there any at 

 Bloomington or Normal, in Mcl-ean ; nor in Dewitt county, which lies south of 

 McLean ; nor in Spring Creek, Iroquois county, which is northeast of Champaign. 



In Kentucky, according to Dr. Smith, it occurred in the northwest corner of 

 the State, about Paducah and adjacent counties south, in 1829, '42, and '55, and 

 it occurred there in 1868. 



In Arkansas, it occupied all the northern counties in 1842, '55, and ^^Z. 



In Alabama, it occupied Russell and adjacent counties on the east side of 

 Black Warrior river, in 1842, '55, and '68. 



In Tennessee, it occupied Davidson, Montgomery, Bedford, Williamson, 

 Rutherford and adjacent counties, in 1842, '55, and '68. 



In North Carolina, it appeared in Mechlenberg county, in 1829, '42, '55, 

 and '68. 



In South Carohna, the Chester district and all the adjoining country to the 

 Georgia line west, and to the North Carolina line north, was occupied with it in 

 1816, '29, '42, '55, and '68. 



In Georgia, it has occurred in Cherokee county since the year 1816. 



*As Mr. Wm. Raucher, of Oregon, Holt county, saw a few individuals in the northeast part of Buchanan 

 county, in 1855, it may occur in small numbers in districts even north of the Missouri river. 

 fEdgar county also has the septemdecim Brood III.
