40 FIRST ANNUAL REPORT OF 



territory occupied by Brood XV. In Pennsylvania, they occupy 

 nearly all the western counties, and their appearance is recorded in 

 1832, '49 and '60, by Dr. Fitch (his second brood), Dr. Smith, and sev- 

 eral of my correspondents; the following counties being enumerated: 

 Armstrong, Clarion, Jefferson, Chemung, Huntingdon, Cambria, Indi- 

 ana, Butler, Mercer and Beaver. 



BROOD XXI.— Scptemdecim— 1867, 1884. 



In the year 1SS4, and at intervals of 17 years thereafter, they will, 

 in all probability, appear in certain parts of North Carolina and Cen- 

 tral Virginia. In 1850 and 1S67 they appeared near Wilkesboro N. C, 

 and were also in Central Virginia during the last mentioned year, 

 while Dr. Smith mentions them as occurring in Monroe county, and 

 the adjacent territory, in Virginia in 1833 and 1850. 



Dr. Harris (Inj. Insects, p. 210) records their appearance at Mar- 

 tha's Vineyard, Massachusetts, in 1833, but as I cannot learn that they 

 were there, either in 1850 or 1867, 1 infer that Dr. Harris's informant 

 was mistaken. 



BROOD XXII.— Septemdecimr- 1868, 1885. 



In the year 1885, and at intervals of 17 years thereafter, they will, 

 in all probability, appear on Long Island ; at Brooklyn, in Kings 

 county, and at Rochester in Monroe county, New York ; at Fall River, 

 and in the southeastern portion of Massachusetts ; at Oakland (Rut- 

 land?), Vermont; in Pennsylvania, Maryland, District of Columbia, 

 Delaware and Virginia ; in northwestern Ohio, in southeastern Michi- 

 gan, in Indiana and Kentucky. 



This brood has been well recorded in the East in 1715, 1732, 1749, 

 1766, 1783,1800, 1817, 1834, 1851 and 1868. It is spoken of in u Haz- 

 zard's Register" for 1834, published in Philadelphia, while Mr. Rath- 

 von has himself witnessed its occurrence during the four latter years 

 in Lancaster county, Pa. 



It is the fourth brood of Dr. Fitch, who only says that it "reaches 

 from Pennsylvania and Maryland to South Carolina and Georgia, and 

 what appears to be a detached branch of it occurs in the southeastern 

 part of Massachusetts." He is evidently wrong as to its occurring in 

 South Carolina and Georgia, and it is strange that he does not mention 

 its appearance in New York, for Mr. F. W. Collins, of Rochester, in 

 that State, has witnessed four returns of it there, namely : in 1817, 

 '34, '51 and '68, while the Brooklyn papers record its appearance there 

 the present season. As these two points in the State are about as far 

 apart as they well can be, the intervening country is probably more 

 or less occupied with this brood. Mr. H. Rutherford, of Oakland,* Ver- 

 mont, records their appearance in that neighborhood in 1851 and 1868. 



*I can find no such post office as Oakland in Vermont, and incline to believe that the Tribune 

 compositor made Oakland out of Rutland, and more especially as Rutland is on the New York 

 border.
