THE STATE ENTOMOLOGIST. 35 



BROOD X—Tredecim— 1862, 1875. 



In the year 1875, and at intervals of 13 years thereafter, they will 

 most likely occur in different parts of Texas. According to Dr. Smith 

 they appeared in vast numbers in some parts of Texas in 1819, though 

 he was not able to get any particulars. 



BROOD XI— Scptemdecim— 1859, 1876. 



In the year 1876, and at intervals of 17 years thereafter, they will 

 in all probability appear in parts of North Carolina, Virginia, Mary- 

 land, Illinois and Indiana. According to Dr. Smith they appeared 

 from Raleigh, North Carolina, to near Petersburg, Virginia, in 1812 

 and 1859; in Rowan, Davie, Cabarras and Iredell counties in the same 

 State in 1825, 1842 and 1859; in the valley of Virginia as far as the 

 Blue Ridge on the east, the Potomac river on the north, the Tennes- 

 see and North Carolina lines on the south, and for several counties 

 west, in 1808, 1842 and 1859 ; in the south part of St. Mary's county, 

 Maryland, dividing the county about midway east and west, in 1825, 

 1842 and 1859; in Illinois about Alton in 1842 and 1859; and in Sulli- 

 van and Knox counties, Indiana, in 1842 and 1859. 



BROOD XII— Septemdecimr- 1860, 1877. 



In the year 1877, and at intervals of 17 years thereafter, they will, 

 in all probability, appear in the vicinity of Schuylerville and Fort 

 Miller, in New York. From thence along both sides of the Hudson to 

 its mouth, where they extend, at least, to New Haven, in Connecticut, 

 and west across the north part of New Jersey and into Pennsylvania. 

 Also in Dearborn county, Indiana; Kalamazoo, Michigan; in Penn- 

 sylvania, North Carolina, Virginia and Maryland. 



This brood is recorded by Prof. Potter as having occurred at 

 North Haven, Conn., in 1724, 1711, 1758, 1792, 1809 and 1S26. It was 

 also recorded by the same writer as having occurred in 1826 in Mid- 

 dlesex county, N. J., and by Dr. Fitch as having occurred in 1S43 

 throughout the whole country mentioned above. In 1860, again, it 

 was spoken of in the old series of the Prairie Farmer (Vol. 22, p. 

 119) as having occurred that year in New Jersey, and Dr. Smith re- 

 cords it throughout the whole State in 1775, 1792* 1809, 1826 and 1843. 

 Mr. Jas. Angus, of West Farms, Westchester county, N. Y., has him- 

 self witnessed its recurrence in the years 1843 and 1860. 



In Pennsylvania, Mr. Rathvon found a few individuals in 1860, and 

 Dr. Smith says it extends from the Susquehanna to the Delaware riv- 

 er, bounded by Peter's mountain on the south. In Virginia it oc- 

 curred from the south part of Loudon county to the Roanoke river, 

 and from the Blue Ridge to the Potomac in 1826, 1843 and 1860. In 

 Maryland from Ann Arundel county to the north part of St. Mary's, 

 and from the Potomac to Chesapeake Bay, in 1809, 1826, 1813 and 

 1860. In Rockingham, Stokes, Guilford, Rowan, Surrey and adjacent
