Mr. W. S. Herrick, Thurrnan, Allen County, Ind., writes under date 

 of June 10, 1898, that '•' We bad the 17-year locust in 1887, if I remember 

 correctly." This is also a doubtful record, and it is possible that he 

 referred either to Brood XXII, occurring- in 1885, or Brood V, occurring 

 in 1888. 



That all these records are open to some doubt is apparent, but they 

 are of sufficient importance to warrant investigation in 1904. 



Brood XV, 1907. — This brood is represented by the colony appearing 

 at Tivoli, Duchess County, and Galway, Saratoga County, N. Y., in 

 June, 1890, as recorded by Prof. J. A. Lintner in his Seventh Report, 

 pages 297-301. Mr. Davis records the occurrence of scattering indi- 

 viduals the same year on Staten Island. In a letter of June 2, 1890, 

 Prof. J. B. Smith, Xew Brunswick, X. J., reports that the periodical 

 Cicada had been taken by several Newark collectors, and had also been 

 observed at Angiesea, Cape May County. 



Another record which perhaps applies to this brood is given by Mr. 

 I. X. Smith, Scotland Xeck, Halifax County, N. C, in letter of June 22, 

 1885. He reports that his " First recollection of the locust was about the 

 year 1839 or 1840, when the whole of the white-oak lands were filled 

 with them. * * * In 1855 or 1856 they appeared again, but nothing 

 to compare with the period first stated. The locusts were all on the 

 white-oak land and on the Roanoke River and not on the xnne lands." 

 Assuming the dates 1839 and 1856 to be the correct ones, this would 

 throw this swarm of Cicadas into Brood XY, and if there are any repre- 

 sentatives left they should reappear in 1907. 



The late Mr. W. S. Robertson, of Muscogee, Ind. T., in letter of June 

 17, 1879, incidentally mentioned also the occurrence of a brood of Cica- 

 das in 1839. This record could not fall in any one of the old broods, 

 and if it belongs to the 17-year race it would be an extreme western 

 outpost of XY. 



Brood XVII, 1909. — A very definite record which may coincide with 

 this brood is furnished by Mr. Theodore Pergande, of this Division, 

 who states that Mr. Rosseau, of Charlottesville, Albemarle County, Ya., 

 informed him that the Cicada was very numerous in that place in 1875. 

 His informant was positive as to the year from its being the one in 

 which he made a trip to Europe. 



Another record is given by Mr. John D. Macpherson, Manassas, 

 Prince William County, Ya., in letter of July 3, 1895. He writes: 

 " I came here on the 23d of June, leaving the Cicada in full song in 

 Washington (Brood X). Finding none here, I made inquiry and was 

 informed that they appeared in full force in this county (Prince Will- 

 iam) in the year 1875. This information I regard as reliable, the date 

 being fixed as the year following the marriage and arrival of my 

 informant in this county." These Yirginia swarms are evidently pre- 

 cursors of Brood I, with which they are therefore closely allied. 



A western extension of this brood seems to be indicated in the 

 record furnished by H. J. Giddings, Sabula, Jackson County, Iowa.
