THE STATE ENTOMOLOGIST. 39 



Pike, Perry, Piatt, Pope, Richland, Randolph, Sangamon, Saline, St. 

 Clair, Union (northeast corner), Washington, Wayne, Wabash, Wil- 

 liamson and White. There were none the present year, either at 

 Decatur, in Macon county, or at Pana in Christian county; nor were 

 there any at Bloomington or Normal, in McLean ; 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 '68. 



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, Wil- 

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



In North Carolina, it appeared in Mecklenburg county, in 1829, 

 '42, '55 and '68. 



In South Carolina, the Chester district and all the adjoining coun- 

 try 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. 



In Louisiana, it appeared in Morehouse, Caddo, Clairborne, Wash- 

 ington and adjacent parishes, in 1855 and '68. 



It also doubtless occurs in Mississippi and Indian Territory, though 

 I am unable to specify any localities. 



BROOD XIX.— Scptemdecim— 1865, 1882. 



In the year 18S2, and at intervals of 17 years thereafter, they will, 

 in all probability, appear in Monroe, Livingston, Madison and adjacent 

 counties, and around Cayuga Lake, in New York. 



Mr. T. T. Southwick, of Manlius, Livingston county, records their 

 appearance there in 1865, and, as will be seen by referring to the 

 Prairie Farmer, vol. 16, p. 2, they appeared during the same year 

 near Cayuga Lake, while Dr. Smith records their appearance in 1797, 

 1814, '31 and 48. 



BROOD XX.— Septemdecim— 1866, 1883. 



In the year 1883, and at intervals of 17 years thereafter, they will, 

 in all probability, appear in western New York, western Pennsyl- 

 vania and eastern Ohio. In the last mentioned State they occur more 

 especially in Mahoning, Carroll, Trumbull, Columbiana and adjacent 

 counties, overlapping, especially in Columbiana county, some of the 



* Though they occurred in large numbers in Davidson county and other portions of Tennessee 

 in 1855, and also the present year, yet in Lawrence county they appeared in 1856, instead of 1855 — 

 another instance of a belated brood.
