No additions have been made to the records of Iowa Cercopidae since the writer presented his papers on this group in 1895 and 1897; in fact, only one new species has been added to the United States list since that time. There have, however, been a number of rather surprising additions and extensions of distribution and some of them point to the probability of two more species being found in Iowa and the distribution of two others being extended beyond what appeared at that time to be their probable limits.
