Modified Segments. — 3" . The eighth tergite, which is quite small in this 

 genus, bears about 6 short hairs above the stigma. The sternite, which is 

 large, is apically truncate-emarginate in side-view, with the angles strongly 

 rounded oif, and bears along the ventral margin and near it about 15 or 16 

 bristles, of which 5 or 6 ventral ones are especially large and are arranged in 

 a row. The clasper (Fig. 3) is about as long above as beneath. Its upper 

 distal angle is rounded off and the lower angle acute. The upper edge bears 

 a number of bristles, of which one is considerably longer than the others. 

 The manubrium is slender, of nearly even width and gently curved upwards. 

 The moveable process (F) projects but little above the upper angle of the 

 clasper and extends far down, as is the case also in several allied species. It

is almost the shape of a sugar loaf, with the lower end rounded. The bristles 

 which it bears are all small, the longest one being placed near the apex, and 

 being about as long as the process is broad at that point. The internal arm 

 of the gth sternite (Fig. 3, ix. st.) is elbowed and very broad, while the 

 horizontal arm is narrow, being narrowest about the centre and widening a 

 little in the apical half, where the gently rounded ventral edge bears a 

 row of short bristles. One long bristle is placed proximally to the middle 

 of the horizontal arm and several smaller ones are still further proximal. —

 angle and then excurved (Fig. 4). The eighth tergite bears about 6 short 

 hairs above the stigma. There is no bristle below the stigma. The lower
