Smithsonian miscellaneous collections . s (fig. 25 H, o, q).The sclerites of the dorsal (anterior) pair end in the meatus, wherethey are united with each other by a transverse bridge {t) the dorsalwall of the latter; the ventral (posterior) sclerites are continuous bynarrow upcurved arms (s) with the lateral plates {n) of the en-6 8o SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 94 dophallic bulb. The posterior angle of each endophallic plate is armedinternally by a free spinelike process (G), below which the marginof the plate extends obliquely downward and forward to the base ofthe gonopore process (3)- Between the gonopore processes, as alreadyshown, lies the gonopore, or true genital aperture (fig. 33 C, Gpr),by which the ejaculatory sac (fig. 25 G, H, ejs) communicates withthe spermatophore sac {sps) of the endophallus.

The epiphallus is deeply sunken in theanterior end of the genital chamber, and the basal fold rises steeplyagainst the anterior surface of the aedeagus (C), concealing inost ofthe basal parts of the latter. The dorsal lobe of the aedeagus has awell-developed cylindrical distal part (D, r) from which project twopairs of apical processes {n, p). The proximal part (in) bears a pairof short but very wide lateral apodemes (D, E, Apa). The endophal-lus is relatively small, but the anterior apodemes (iv) of its lateralplates are large and widely divergent (E).
