" In 1880 there was a considerable quantity of tlie Cicadas in this county. They 

 made tlie Avoods ring and did some damage to fruit trees,'' 



JSorih Carolina. — Mr. F. B. Shuford, of Holly Springs, Miss., wrote us on June 18, 

 1885: *' I recollect they (the (Ucadas) were in Lincoln C!ounty, N. C, about 1828." 

 This is an indehnite statement, which needs verification. Mr. 1). B. Mclver, Moore 

 County, N. C, reported that Cicadas in 1880 were "in the piney w^oods of this 

 county, but not in tlie oak woods."' 



BROOD XI -SI:PTENDECIM (1876-1898). 



This i.s an old-establislied and well-known brood, tliongh nincli remains 

 to be learned regarding its extent, and a few of the reported localities 

 need verification. As in some of the other 17-year broods, and more 

 es])ecially Brood XXII (1885-1902), the present one occnrs in two divi- 

 sions or branches, the eastern branch (in Xorth Carolina, and Virginia) 

 representing the bulk of the brood and the western branch being broken 

 np into several well-separated detachments. Compared with other 17- 

 year broods. Brood XI is of rather southern distribution, /. c, its north- 

 ern limit, so far as known at present, is the mouth of the Shenandoah 

 River, the western detachments following nearly the same latitude 

 (about along the 39th parallel). In its southern extension along the 

 Alleghany Mountains it is only exceeded by Brood XXII, but it occu- 

 pies a considerable area in Xortli Carolina and Virginia well toward 

 the east of the mountains which is not the case in Brood XXII. It 

 always appears one year in advance of another well-known 17-year 

 brood viz. Brood XII (1877-'94), and there is evidently a relation 

 between the two, for a glance at the territory occupied by both shows 

 that Brood XII is the northward continuation of Brood XI, extending 

 along the eastern iiank of the Alleghanies as far north as Albany and 

 Troy in Xew York. South of the Potomac the two broods do not exactly 

 overlap, but run parallel Avith each other. Brood XI occupies the valley 

 of Virginia west of the Blue Bidge and a strip halfway between the 

 mountains and the ocean, whereas Brood XII occupies a rather narrow 

 strip along the eastern flank of the mountains through Virginia to north- 

 ern Xorth Carolina. The following is the list of the localities known 

 for Brood XI, the majority of them (already published in Bulletin Xo. 

 8 of this Division or previously) being here repeated without further 

 comment : 



North Carolina. — From Raleigh, Wake County, to the northern line of the State; 

 also in the counties of Rowan, Davie, Cabarrus, and Iredell. 



Virginia. — From near Petersburg, Dinwiddie County, to the southern line of the 

 State; Bedford County; Valley of Virginia west of the Blue Ridge from the Potomac 

 River on the north to the Tennessee and North Carolina lines on the south. 



District of Columhia. — Noticed, the j^resent year, early in June, in the woods north 

 of Washington and along Rock Creek. 



Maryland. — Southern half of St. Mary's County. 



Kentucky. — Trimble County, in the northern part of this State, has been added to 

 the localities occupied by this brood on the strength of the following communication 

 by Mr. W\ J. Parker, Bedford, Trimble County, dated June 25, 1885: ''My first 

 remembrance of the visitation of the Cicada was in 1855, when they were very numer- 

 ous ; then they appeared again in 1859 and again in 1872." The years 1855- 72 plainly
