BROOD XVI 8EPTENDECIM 1908. 63 In Bulletin 14 and older pid)lications a western outpost in Boulder County, Colo., was reported for this brood. This record is undoubt- edly erroneous, and arises from the confusion of one or other of the mountain species of Cicada which also have life cycles of several years and duplicate somewhat the habits of the eastern species. Prof. C. P. Gillette, in answer to an inquiry by the writer, states that he does not believe that septendecim occurs in Colorado, inasmuch as he has not found a single example of it in the course of the insect collecting done there by himself and students during the last sixteen years, and he suspects that the insect reported is Tibicen rimosa Say, which might readily have been mistaken for Fig. 20.—Map showing distribution of Brood XVII, 1909. The distribution, by States and counties, is as follows: Arkansas.—Franklin. Iowa.—Lee (?). Nebraska.—Richardson. Brood XYU—Seplendecim—1909. (Fig. 20.) This brood is a precursor of Brood I, and was indicated by the writer in Bulletin IS (new series) of this Bureau. It comprises small or doubtful colonies only. The records given in that publica- tion are reproduced below without change except for the addition of two new localities for Virginia, one in Appomattox County and the other in the southwestern part of Washington Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States.
