THE PERIODICAL CICADA. «?«"s THE IT-YEAR AND 

 13-YBAR LOCUST. 



In thf Missouri Entomolofiical R('i»i>rf for 1SG8 

 will ln> found tlie following- account of two 

 lirooils of tliese singular insects, wliicli arc to 

 ajijK'ar the present s^ison: 



BROOD til.— Sp/)/fmrfccim— 18.')3, 187(1. 



In tlic year 1870, and at intei-vals of seventeen 

 \ (!iirs thereafter, they will iii aH probability ap- 

 pear in what is known as tlie " Kreitz Creek 

 Valley," in York county. Pa., and possibly in 

 Vinton couutv, Ohio, and Jo. Daviess couuty,

 season (I86y— Ib-ood X.Xll). But on the south- 

 west side of the raui;v. in what is known as the 

 Kreitz Creek Valley, ilii'iv were none. Tliey 

 appeared last in thi- valle\ in l^^'.e. and previous 

 to tiiat year at interval of -i\enleen yearsfroin 

 time immemorial."' l>r. Smith records tlieir ap- 

 pearance in 1853, both in \ inton couuty, Ohio, 

 and Jo. Daviess county. Illinois. 



BROOD IV.—Tredecim—lSol, 1S70. 



In the year 1870, being tlie same as tlie preced- 

 ing, they will in all probability appear in Jackson, 

 Giulsdeii and "Washington counties, Florida, 

 having appeared there according to Dr. Smith in 

 1844 and '57. 



"We earnestly ask our subscribers, who happen 

 to live in the several parts of the country there 

 nicntioned, to report to us whether or not the 

 insects appear according to ijrediction, as we 

 wish cither to verify and confirm, or disprove, 

 the gciuiincness of these broods. "We have every 

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

 api)ear. as our eorresponih'nt. Mr. IJafhvon, who 

 has ol)served it in past years, is still living to 

 make further observatious ; but as Dr. Smith, 

 who recorded the appearance tif the 13-year brood 

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

 to have its periodic visits, at inteiTals of thirteen 

 years, confirmed. 



If any of our Georgia subscribers can give us 

 the proper information, we should also very inuch 

 like to know whether or not the Periodical Cicada 

 appeared last year (186'J) in Habersliani. Musco- 

 gee, Jasper, Greene, "Washington and adjacent 

 counties in that State.

THE DEATH-WEB OF YOUiNti TROUT. 



Soon after the article on page 174, with the 

 above heading, was in type, we received from 

 Mr. Seth Green specimens of the web-worm in 

 question, and the mystery was soon solved. The 

 worm is the laiwa of a two-winged fly belonging 

 to the genus Shmdidm. the species of which arc 

 so well known to torinent both man and beast by 

 their irritating bites. In our next number we 

 ■shall publisli an interesting article on the trans- 

 formations of tlii> L:cnn>. IVoni the pen of Baron 

 Osten Sacken. aceoinpanied by fitting illustra- 

 tions. 



Choice Flowers.— We thankfully acknowl- 

 edge the receipt, in excellent condition, of a fine 

 assortment of Greenhouse and 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 no wonder that Mr. S. receives so large a 

 share of the Western patronage, for he well 

 deserves it; and our readers, who wish assort- 

 ments of plants well grown, will do well to send 

 to 100 Madison street, Chicago, for a catalogue.
