DISTRIBUTION OF Broops XXII, V anv VIII, oF CicADA SEPTENDECIM, IN 
InpIANA. By F. M. WEBSTER. 
It was my good fortune, while located at Lafayette, Indiana, during 
the years 1884-90, as a special agent of the United States Department 
of Agriculture, Division of Entomology, to have an opportunity of study- 
ing the distribution of these three broods of the periodical cicada. 
On consulting the accompanying map and explanation thereto, it will 
be observed that Brood XXII, 1885, covers the entire State, except a 
small area around the lower extremity of Lake Michigan. This strip of 
country is much narrower at the Michigan line than it is at the Illinois 
line, including as it does only the extreme northwest corner of Laporte 
county, the dividing line between this and Brood V being, here, between 
the village of Otis and the city of Laporte, crossing the line of Porter 
county about Wanatah, and passing across Lake county, in the vicinity 
of Orchard Grove. 
This is the strongest of all the broods in Indiana and covers by far 
the greatest area. Its next recurrence will be in 1902. 
Brood V covers only the area over which Brood XXII did not occur and 
does not, so far as I was able to learn, overlap that brood. It covers a 
15—Scrence.
