teeth are on the two sides together in the ^ 6, 6 or 7, 5 or 6, 4 to 6, 2 to 

 4, 2, and in the 9 4 to 6, 6 to 8, 5 or 6, 2 to 6, o or 2, o. The sternites 

 of segments 4 to 6 bear in 9 o^i eacli side a row of four bristles, the 

 sternite of the seventh segment a row of seven or eight bristles, there 

 being in the (^ three bristles on the sternites of segments 3 to 7. At the 

 apex of the seventh tergite there are three bristles in both sexes, 

 the first and third being in the S rather shorter, but somewhat thicker 

 ihan the lower bristles of the postmedian row, while in the 9 the third 

 bristle attains nearly the length of the central one, the upper bristle being 

 a^ .>hort as in the ^. The stylet of the $ is about two and one-half 

 times as long as it is basally broad. 



Legs. — There are on the outer side of the hind femur two bristles 

 behind the ventral subbasal sinus, one bristle above the sinus and a 

 small subventral one further back ; posteriorly at the apex there are two 

 subventral bristles on the outer side and one on the inner. 



The propor'.ional length of the mid and hind tarsal segments is as 

 follows : 



Modified Segmeiits. — ^. The eightli sternite is rounded truncate at 

 apex, bearing a number of long bristles (Fig. 43, VIII st). The 



manubrium (M) is acuminate and slen- 

 f ? der. The process (P) of the clasper 



reaches to the apex of the finger, its 

 tip being rounded. The finger (F) has 

 the shape of a half crescent, the distal 

 (= ventral) edge being almost regu- 

 larly rounded, bearing three long and 

 some short bristles. The ninth sternite 

 bears five long bristles and a number 

 of small hairs (IX st). 9 • — The 



seventh sternite bears a small sinus. 

 On the eighth tergite there are three or
