THE PRESENT YEARS APPEARANCES OF THE PERIODICAL CICADA, 



We call attention to the localities in wliicli this cnrious insect will 

 doubtless appear the present summer. Two dili'erent broods, one a 13- 

 year and the other a IT-vear brood will appear and will have been mak- 

 ing the woods resound with their peculiar song in their respective 

 localities before this number of Ixsect Life is received. We shall be 

 exceedingly obliged to any readers or correspondents who will send us 

 word of the occurrence of this insect in their own locality, or any facts 

 additional to those here indicated, or any information that tends to 

 confirm, correct, or amplify the records. We should like particularly 

 to have exact data as to the limits of the appearance in any particular 

 township or county. 



BROOD XVI— TREDECIM (1880-1893). 



In the First Eeport on the Insects of Missoui'i the senior editor estab- 

 lished this brood solely on the testimony of Dr. G. B. Smith, fi'om the 

 single locality of southern Georgia. Since then he has obtained con- 

 firmatory proof of its existence not only in Georgia but in other parts 

 of the south. It is now known from four States, but the special locali- 

 ties are much scattered and this fact is due, in all probability, to want 

 of more carefnl observation, or to the incompleteness of reports. It 

 is obvious, however, from the localities given below that this Brood 

 XTI is confined to the southern States and does not extend into the 

 Mississippi Valley. 



It may be further noted that this brood is the forerunner of the largest 

 13-year brood known, viz. Brood XTIII (1881-*94). which occupies the 

 Mississippi Talley. as well as the southeastern States. These two 

 broods occupy, in fact, the same relation to each other as do the small 

 13-year Brood TI (1884-'97), and the second largest 13-year Brood YII 

 (1885-'98), although Brood TI is confined to the southern part of the 

 Mississij)pi Valley. The localities so far known for Brood XVI, which 

 appears the present year, are as follows : 



Alabama. — The folio-wing very definite statement was received in 1885 from Mr. 

 William M. Garrett, Mount Willing, Lowndes County : The 13-year Locust will not 

 make its apj)earance in this county until 1893. Your corresj)ondent can remember 

 their appearance in 1841, 1854. 1867, and 1880. There are no 17-year Locusts in this 

 county. 



Tennessee. — Mr. "W. F. Eass.. of Fayette^nlle, Lincoln County, wrote us as follows 

 in 1885: '^The Cicadas gave us a call in 1880, whether of the 13- or 17- year varieties 

 I have no means of finding out, hut I do know that they were very numerous." 

 This locality is on the southern line of the State, and falls within the territory of 

 this Brood and not within that of the 17-year Brood XY. which also appeared in 

 1880. 



Georgia. — Cherokee County, according to Dr. G. B. Smith (not yet verified). Cobb 

 Countv. as indicated bv Mr. H. M. Hammett, of Marietta, who wrote us in 1885:
