Chlorotettix unicolor, Fitch.—An examination of the Fitch type in the National Museum shows this to be the form described by Mr. Van Duzee as galbanata. As this will leave Mr. Van Duzee's unicolor without a name, it may be known as Vanduzei. Vanduzei differs from all the other described species in a character not before noted—the ocelli are distant from the eyes,—while in all others they are about as near as their own width or nearer. Differing thus widely from other species referred here, Vanduzei must still remain the type of the genus, which should perhaps be used for it alone. The male of unicolor, Fh.. closely resembles in genital characters that of spatulatus which I have from Kansas and Texas.
