Modified Segments. — c?. The eighth tergite has about ten long bristles in the 

 dorsal half and a nearly vertical row of three pro.ximally from near the ventral 

 edge upwards. The eighth sternite is long, narrow, and rod-like, bearing at the 

 apex two long bristles and a number of shorter ones further back (PI. VI. fig. 3). 

 The finger is long, bearing three blunt spines, and above them a bristle as shown in 

 the figure, another bristle standing at the u])per edge near the proximal angle 

 (PI. VI. fig. 3). The proximal portion of the ninth sternite (ix. st.) is short and 

 rather narrow, bearing two bristles near the sinus, one short spine-like one beyond 

 them, and about fourteen hairs proximally of them. The distal portion of the ninth 

 sternite is long and large, bearing proximally at the ventral edge numerous short 

 bristles, the ventral portion being moreover sinuate near the apex. 



? . The seventh sternite is truncate, with the upper angle produced as a broad 

 rounded lobe (PI. VI. fig. 2). The eighth tergite bears three bristles at the apex 

 and three short spine-like ones proximally of them, besides a number of short and 

 long bristles as shown in the figure (PI. VI. fig. ",'). The stylet is about twice as 

 long as it is broad. The spine-like bristles on the anal sternite are heavy and curved.
