THE PERIODICAL CICADA. nii„x THE 17-YEAR AND 

 i:i-YEAK LOCUST. 



Ill tlio Missouri Eiiloiiioldiiical Kcport tor 1868 

 will be I'ouiLil tlie followiiiu' account of two 

 l)roo(ls of those sini;'ular insects, wllicli arc to 

 appear llio in'escnt season: 



BKOOD 111.— Sfj)/pmi/«im— 18.">3, J87ii. 



In the year 1870. and at intervals of seventeen 

 years thereafter, they will in all probal)ility aj)- 

 pear in what is known as the "Kreit/. Creek 

 Valley." in York <'ounty. Pa., and possibh in 

 Vinton countv. Ohio, and Jo. Daviess county. 

 Ills. Mr. 8." S. Ifathvon. of Lancaster. Pa'., 

 speakiuf;' of this hrood. says : •■Lancaster countv 

 is l)oun(h'd on the southwest hy the Susiinehanna 

 rivei-. dividing- it from the couiity of York, along- 

 the northeastern margin of which tlieve is a 

 mountain range sloping down lo the river. Along 

 that slope Cicadas were ahnndant tlie present 

 season (1868— Brood XXII). But (ui the south- 

 west side of the range, in what is known as the 

 Kreitz Creek Valley, there were none. They 

 apl)eared last in this valley in 18.^3, and previous 

 to that year at intervals of s<'venteen years from 

 time immemorial.'' Dr. Smith records their aji- 

 pcarance in l8o3, both in Vinton county. Ohio, 

 and Jo. Daviess county, Illinois. 



BROOD IV.— rrerffcira— lS.-)7, l.sTll. 



In the year 1870. being the same as the preced- 

 ing, they will in all probability appear in Jackson, 

 Gadsden aud Washington ('ounties, Florida, 

 having- appeared there according- to Dr. Smith in 

 1844 and '57. 



"VYe earnestly ask our subscribers, who happen 

 to live in the .several parts of the country there 

 uiuntioned, to report to us whetlier or not the 

 insects appear according to prediction, as we 

 ^vish either to verify and conlirm, or disprove, 

 the genuineness of these broods. We have every 

 confidence that the 17-year brood (III.) will duly 

 appear, as our correspondent. Mr. Rathvoii, who 

 has observed it in past years, is still living to 

 uiiikc further observations; but as Dr. Smith, 

 who recorded the appearance of the 13-year brood 

 (IV.) is now dead, it would be very gratifying- 

 to have its periodic visits, at inteiTals of thirteen 

 years, conlirnied. 



If any of our Georgia subscribers can g-ivc us 

 the proper information, we should also very nmch 

 like to know whether or not the Periodical Cicada 

 appeared last year (186'J) in Habersham, Musco- 

 gee, Jasper, (lireene. AVashiiigton and adjacent 

 counties in that State.

THE DKATII-WEB OF YOUN'(i TROUT. 



Soon after the article on page 174, with the 

 above heading, was in type, we received from 

 Mr. Seth Green spc'ciinens of the web-worm in 

 cpiestion, and the mystery was soon solved. The 

 worm is the larva of a two-winged fly belonging- 

 to the genus Simuliiim. the species of which are 

 so well known to torment both man and beast by 

 their irritating bites. In our next number we 

 shall publish an interesting article on the trans- 

 foriiiations of this genus, from the pen of Haron 

 Osteii Sacken, accompanied by titling- illustra- 

 tions. 



Choick Fi.owkrs. — We thankfully acknowl- 

 edge the receipt, in excellent condition, of a tine 

 assortment of Greenhouse aud Bedding plants, 

 from the well-known Chicago florist, Edgar 

 Sanders. We never before received plants from 

 a distance that looked so fresh and healthy. It 

 is uo wonder that Mr. S. receives so large a 

 share of the Western patronage, for he well 

 deserves it; aud our readers, who wish assort- 

 ments of plants well grown, will do well to send 

 to 10(» Madison street, Chicago, for a catalogue.
