In 1908 Professor T. D. A. Cockterell, (Trans. Am. Ent. Soc., xxxiv, 247-254) reviewed the American species of the Family Nemestrinidae occurring North of Mexico, including the fossil forms, and in that paper three species of the genus Rhynchocephalus were considered. During the summer of 1922 the author captured a number of specimens of a species of Nemestrinidae while on a collecting trip at Baldwin Hill, about 12 miles from Lawrence, Kansas.
