Mr. Hopkins in his Bulletin 68 gives records indicating possible swarms in Putnam and Lincoln counties, W. Va. None of these eastern records can have other than chance time relation with the mam area covered b}^ this brood. As the periodical Cicada is limited to forested areas, the broods occurring in prairie districts of northern Illinois and adjoining States are necessarily much broken and scattered, and Brood XIII occurs, therefore, for the most part in small colonies in woods bordering streams. No special effort was made to get records in 1905, and this.
