examination). The small superior reflexed acute-triangular lamella, which closes the 

 anus from below, is only a sort of appendage of the base of the real penis. The 

 homologues of these pieces may be found in other Locustidse, i. e. in Decticus, in which 

 genus the penis forms a thick rounded fleshy mass, divided in superimposed lobes, and 

 presenting at the base a sort of separate part, which, when removed, appears as if 

 formed of two lobes, with their inner margins chitinized and black. The superior 

 reflexed lamella in Pherterus and Glaphyrosoma must be the homologue of this basal 

 mass. In different Phaneropterinse there is also at the base of the penis a sort of 

 pyramidal tubercle, which is probably another modification of the same part.
