folding being due to pressure. Behind the shield is visible a small 

 segment representing probably the seventh to ninth segments. Legs 

 very long and rather thin. The cucullus and legs minutely punctate, 

 the cephalothorax and abdominal shield coarsely punctate. The 

 tibia and metatarsus of the second leg and the terminal abdominal 

 joint smooth. 



The ventral surface is not sufficiently Well preserved to show the 

 arrangement of all coxae, but the third and fourth coxae are dis- 

 tinctly contiguous. In the anterior part of the abdomen there is a 

 strongly procurved fold represented by the two lines in text figure 49.
