into a point. Genital segments: in the , two are visible; the first 

 formed like the abdominal segments ; the second on the upper side has 

 two short, horny processes ; on the under side it is somewhat convex, and 

 at the end, which is broad or narrow, is somewhat recurved ; sometimes 

 also there is a slight impression on each side. In the , the first segment 

 is scarcely visible, and the second and third are formed like the abdominal 

 segments, the second being shorter than the third. On the underside 

 they are cleft in the middle, but not parted, [the margins of the cleft 

 forming a raised sutural line. The genital segments are of the same type 

 in all the genera.
