County, Va., 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 Wilham County, Va., 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 

 William) 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 Virginia swarms are evi- 

 dently precursors 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. 

 He writes, " during last June (18'J2) the periodical Cicada was quite 

 common here. * * * j thought it was unusual to find them in 

 such numbers four years after their regular appearance. The last 

 regular year was 1883." (See Insect Life, Vol. V, page 200.) 



If belonging to the 17-yea.r race, the two records following should 

 also be assigned to this brood. Mr. A. J. Julian, Woolleys Ford, 

 Hall County, Ga., reports under date of June 14, 1898, that the 

 Cicada was present there in 1892. Mr. J. W. Seaton, Strasburg, 

 Cass County, Mo. , writes under date of June 9, that the Cicada last 

 appeared in that county in the summer of 1892 and in the summer 

 of 1S9G, being numerous both years. The 189G record refers to the 

 17-year Brood IV, and hence the record of 1892 is probably also of 

 the 17-year race occurring in the same district. 



The scattering specimens recorded by Mr. Davis as occurring on 

 Staten Island in 1892 may also be assigned to this brood. 



NEW BROODS, 13- YEAR RACE. 



Brood XXIV, 1899.— Mr. P. Lynch, Commerce, Scott County, 

 Mo., under date of December 24, 1874, reports that the Cicada ap- 

 peared in the summer of 1873 in considerable numl)ers, coming in 

 June and remaining about two months. "Their eastern limit in 

 this county (Scott) was the Mississippi River, but they were as nu- 

 merous on the opposite side of the river in Alexander Count3^ 111." 



Mr. W. S. Campere, Pickens Station, Holmes County, Miss., writes 

 under date of February 27, 1875, that the Cicadas appeared in great 

 numbers in April, 1873. These two records would indicate a brood 

 originating doubtless by retardation of individuals of Brood XXIII. 



Brood XXIX, 1894-. — It is possible that the following records 

 apply to a 13-year race, and in that case should be assigned to our 

 Brood No. XXIX.
