THE STATE ENTOMOLOGIST. 33 



the extreme southwestern corner of Mississippi, and in the adjoining 

 part of Louisiana. Dr. D. L. Phares of Newtonia (near Woodville), 

 Miss., says that in 1858 they extended over most of Wilkinson and 

 part of Amite counties, Mississippi, and East and West Feliciana, La. 

 He has himself witnessed the appearance of this brood during the 

 years 1832, 1845 and 1858, while it is distinctly remembered by aged 

 people in his neighborhood as having also appeared there in the years 

 1806 and 1819. Dr. Smith gives their range from the Mississippi river, 

 east to a ridge 45 miles from the river that divides the State, north 

 and south, and north and south to the boundaries of the State ; re- 

 cording them as occurring in 1806, '19, '32, '45 and '58. 



BROOD VII.— Tredecim— 1859, 1872. 



In the year 1872, and at intervals of 13 years thereafter, they will 

 in all probability appear in Jackson county and around Cobden and 

 Jonesboro, in Union county, South Illinois, in Kansas, Missouri, Geor- 

 gia, Louisiana, Tennessee and Mississippi. 



According to Mr. Paul Frick of Jonesboro, they were in Union 

 county, Ills., in 1858, and he also thinks it was a great year for them 

 about 1832. Those ot 1858 were probably premature stragglers of the 

 1859 brood, while Mr. Frick is most likely mistaken as to the year 

 1832, since the ftev. George W. Ferrell of Cobden, Union county, 

 witnessed their appearance at that place in 1833, and also in 1846 and 

 1859; and Cyrus Thomas has also recorded their appearance in 1859 

 in the 5th Rep. of the Ills. State Agr. Soc, p. 458*, while a paragraph 

 in the Baltimore (Md.) Sun of June 13, 1859 says "the locusts have 

 made their appearance in 'Egypt' in Southern Illinois, and cover 

 woods and orchards in swarms." This brood not improbably extends, 

 westward into Missouri, for several of the old settlers around Eureka, 

 in St. Louis county, Mo., recollect it being "' locust year" about the 

 time of its last appearance, while Mr. L. D. Votaw of Eureka, and 

 Wm. Muir of Fox Creek, Mo., both believe it was exactly 9 years ago,, 

 or in the year 1859. Dr. Smith records it in DeKalb, Gwinnett and 

 Newton counties, Georgia, in 1846 and '59 ; in the northern part of 

 Tennessee also, in 1846 and '59; in the whole eastern portion of Miss- 

 issippi from the ridge which is 45 miles from the river, on the west,, 

 to the eastern boundary, in 1S20, '33, '46, and '59 ; in Carrol Parish, 

 Louisiana, in 1859 ; and in Philips county, Kansas, in the same year. 



By referring to Brood XV, it will be seen that in 1846, or during 

 the first year of the Mexican war, this 13-year brood appeared simul- 

 taneously with a 17-year brood in western Pennsylvania and Ohio. 



* If Mr. Paul Frick is correct, the brood he has witnessed may possibly be a detachment of 

 the Mississippi and Louisiana Brood VI ; in which case the Cicadas appear for two consecutive 

 years in Union county, Ills., as they do (See Broods XIII and XIV); in Central Ohio, and portions 

 of Northwestern Missouri.
