First tarsal joint short, squarish, bilobed distally; second tarsal 

 joint four to five times as long as broad, its inner (ventral) bor- 

 der only slightly curved, the outer (dorsal) somewhat more arched 

 (PI. 1, Fig. 4). Claw short and rather stout, less than a third 

 the length of the second tarsal joint; somewhat curved towards 

 the tip; auxiliar}^ claws wanting. The coxal and femoral joints 

 are only sparsely armed with short spines, which become longer 

 and more numerous on the tibial and tarsal joints, especially long 

 bristles (about as long as the breadth of the segments) occurring 

 along the dorsal margins of the second tibial and second tarsal 

 joints. On the ventral side of the second tibial joint near its dis- 

 tal end begin a number of thickly set short spines, which be- 

 come more numerous on the tarsal joints and give to them a 

 comb-like appearance. No "heel" is developed on the foot. 



A few ova could be distinguished in the femoral joints, and the 

 openings of the oviducts could be seen in the usual position on 

 the ventral side of the second coxal joints of the second, third, and 

 fourth legs, and they were probably present also on the first pair 

 although they could not be made out. 



Color in alcohol yellowish or light brown.
