Notes on the Cercopidae with descriptions of some news species

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. The Cercopidcc are a strikingly distinct group from the fact that their larvae produce a frothy secretion inside of which they develop. This froth or spittle appears to serve the double purpose of concealment and absolute protection from all parasitic forms, as no parasites of Cercopidcc have been found. The food plants and larvae of quite a number of species are as yet unknown and among them are the four mentioned below. Tomaspis bicincta. This is the only representative found in the United States of a tropical group large in numbers and in size. It is found in the southern states and up the Atlantic coast to Massachusetts. The only record for Iowa is the single specimen taken by the writer at Ames in 1893. This was thought at the time to be a specimen that had been blown up from more southern locations. The IOWA
