The first paper is a systematic treatront of the Arerican species of the genus Scellihron Klug. The first part of the paper is devoted to a detailed study of the external anatomy and male genitalia, followed by tables showing the position of this genus in the superfarrily Fihecoidea. This in turn is followed by a key to the Arerican species included in the genua, and redescriptiors of the different species.
