The lateral profile of the seventh segment (fig. 1) somewhat 

 resembles that of an inverted gun-stock, its upper edge being 

 oblique, and almost angulated near the base; its lower edge 

 curved slightly, and the segment itself being expanded towards 

 the apex ; its posterior edge is convex. The eighth segment is 

 very like the seventh. The dorsal extension of the ninth seg- 

 ment seems oblong, and has raised edges. At its abrupt apex 

 are the triangular app. sup. (fig. 2) . The app. interm. has a

minute oblong projection (fig. 3 6) at the apex of the first joint, 

 which is applied to the underside of the second joint. The 

 second joint is flattened from above downwards, curved inwards 

 at the tip, and bidentate within. The ventral extension of the 

 segment seems somewhat triangular and truncate. The filiform 

 app. inf. fall short of the tip of the first joint of the app. interm. 

 (fig. 3 a). Projecting above them are the broad and flattened 

 penis- sheaths, which are somewhat expanded just before their 

 oblique apices, and which end in two short triangular points 

 (fig. 3 c).
