Text-Figure 30.—Pattern of distribution of the genus Ommatius Wiedemann. the abdomen scanty, appressed and setate, the surface pollinose; the first tergite has 4 or more lateral bristles on each side. Postlateral margins of remaining tergites with or without bristles; in the type of genus such bristles are scarcely present. Males with eight tergites, the last being quite short but not concealed. Females with eight, the last being half as long as the seventh. ISIale terminalia not rotate, and with well developed superior forceps, curved and apposed apically, which are with or without a dorsal notch. Gonopod shorter; the hypandrium is about a fourth the total length of the terminalia. Females with the terminalia quite short, the dorsal proctiger barely protruding beyond the eighth tergite. This is a large and widely distributed genus particu- larly abundant in the Old World and South Pacific. It is peculiar because, although species are found in North America up to 45° north latitude, they appear to be completely absent from Europe; thus far only three species are known from the whole Palaearctic region and none are found south of Brazil.
