nearly so thick and long. The pattern of the cephalothorax 

 differs in having pale median and marginal stripes, with a 

 darker yellow-brown area between, instead of black, and the 

 median area on the upper side of the abdomen pale instead of 

 dark. Its larger size also distinguishes it from the former. 



It will be seen from the measurements below that in the male 

 the first pair of legs is longest, while in the female it is the fourth 

 pair. There is no appreciable difference in the length of the 

 tibia and patella iii. and iv. in the female, while in the male those 

 joints in the fourth pair are only very slightly longer. 



The measurements (in millimetres) are as follows : — 



Male.
