The distal part of thedorsal lobe of the aedeagus is unusually long (D, E, r) and is pro-duced into two terminal lobes laterad of the phallotreme cleft. Thedorsal apical processes («) thus come to project anteriorly below thesummit of the terminal lobes. With the base of each of these processesthere is connected a soft padlike lobe (E, /). The ventral apical proc-esses are concealed within the phallotreme cleft as in the last species. Melanoplus femur-rubruin (Degeer).^—The exposed characters ofthe male abdomen of this species are shown in figure 39. The phallicorgans are entirely concealed in the usual manner within the genitalchamber (fig. 40 B). The epiphallus (A, B, Epph) is very large,especially as to its lateral lobes. Behind the epiphallus the genital. Fig. —End of the male abdomen of Melanoplus fciiiitr-nibruin (Cyrta-canthacrinae). A, lateral view. B, dorsal view. chamber floor is elevated in a large cushionlike structure, the anteriorpart of which rests against the posterior epiphallic lobes, while thedeeply cleft posterior part forms a thick bilobed basal fold (bf) cover-ing the basal part of the aedeagus. The aedeagus (B, Aed) consistsof an irregular dorsal lobe, and of a simple relatively small ventrallobe (vl). The dorsal lobe shows the usual subdivision into a proximalpart (m) and a distal part (r), the latter bearing a single pair oflarge apical processes (n), which, as in other species of Melanoplus,are the usual anterior dorsal processes. Connected with the base ofeach of these processes is a soft, flat accessory lobe (C, /) lying onthe dorsal surface of the base of the aedeagus. The ventral processes,as appears to be characteristic of Melanoplus, arise deeply withinthe phallo
