The family Pyrgomorphidae comprises about four hundred or so known species of grasshoppers, the majority of which are from tropical and subtropical countries, chiefly of the Old World. The morphology, other than that of the phallic complex, has not been critically studied in the course of this work. The following general characters of the group are, therefore, mainly those given by more recent authors such as Slifer (1940a), Laird (1943), Rehn (1953b), Kevan (1955; 1959; 1961a), Dirsh (1956; 1961a) and Helwig (1958). The chief distinguishing features of the family are as follows.
