SEVENTEEN-YEAR LOCUST: BROODS IN NEW YORK. 171 



What is apparently the same brood seems also to extend into Mary- 

 land, Virginia and North Carolina; also into Michigan and Indiana, or 

 perhaps, these last may be a coincident brood. 



The records of this, date back to over a century and a half, viz.: to 

 1724, in New Haven, Conn. Subsequent returns were in 1741, 1758, 

 1775, 1792, 1809, 1826, 1843, i860 and 1877. In the last recorded year 

 they were very abundant in the vicinity of Albany. Large numbers of 

 these were found to be infested with a fungus, which was described and 

 named by the State Botanist, Prof. Charles H. Peck, as Massospora cica- 

 dina. 



5. A brood in 1900 in Western New York. Former years of its ap- 

 pearance were 1832, 1849, 1866 and 1883. Its range is apparently not 

 very extensive, as it seems to be limited to Western New York, Western 

 Pennsylvania and Eastern Ohio. It is Dr. Fitch's 2d brood; Riley's 

 No. XX. Miss M. H. Morris, of Germantown, Pa., to whom we are 

 indebted for .many valuable observations upon this insect, has recorded 

 it as occurring in the year 1849 "in the northern portion of New York, 

 from Buffalo through the entire length of Genesee county" {Proc. 

 Bost. Soc. Nat. Hist., iv,.i85i, p. no). This would give it a distribu- 

 tion at that time centrally through Erie, Wyoming and Genesee counties, 

 with probable occurrence in Niagara, Orleans and Monroe counties. 

 Since that time its range seems to have become more restricted and its' 

 numbers reduced. Our only knowledge of its appearance in 1883 is 

 from an item in the Neiu York Herald of about July 10th, that a 

 '' swarm of locusts," doing much damage, had appeared in Chautauqua 

 county, the extreme south-western corner of the State. 



In a former publication, I included with the above, a sixtli New York 

 brood — the xviiilh of Prof. Riley — of which he predicted the return 

 in 1881, of a few in Westchester county, based upon the observation by 

 Mr. James Angus, of "straggling specimens" in Westchester county in 

 1864. But, as Mr. Angus informs me that in that year he " saw a few 

 odd ones only, not more than two or three, although hunting pretty 

 closely," and that in i88r, none were seen by him, it would obviously 

 be improper to cite the above very limited appearance as a New York 

 brood.* 



In the above statement of years of appearance and range of distribu- 



[*It3 return was, however, noticed by Mr. W. T. Davis, upon Staten Island, N. Y, who 

 reports, in Entomolofiica Amenvana, i, 1835, p. 92: "On May 8, 1881, while collecting in- 

 sects with Mr. Leng in the neighborhood of Watchogue, Stat. Isl., we found a red-eyed 

 Cicada pupa under a stone, and on June 5, eight specimens were collected, all of them males, 

 and many of them being wet, having recently emerged. By the 12th of June they had 

 become quite numerous, and I noted at the time that about one tree, I counted fifty-two 

 pupa skins of the red-eyed Cicada."]
