The single flat triangular tooth, about the middle of the inner 

 falx-sheath margin, is particularly large, and the anterior tooth 

 of the outer margin is also rather large. 



There is a row of three short spines in front of each femur 

 above, with two single spines about the middle. On the under 

 side of tibia i. and ii. are three pairs of long powerful spines 

 and two smaller spines on the inner side ; on metatarsus i. and ii. 

 underneath are two pairs of long spines ; on metatarsus iii. and iv. 

 are a pair near the base and a bunch at the anterior end, and 

 on tibia of same two above, two on the side, and a pair under- 

 neath. On the femoral joint of the palp are two spines, on the 

 patella one on each side, on the tibia one above, and on the distal 

 joint one below.

Male. Similarly coloured to the female, the sides of the cephalo- 

 thorax being, however, darker brown and the brown stripes on 

 the abdomen continuous ; the brown area on the under side also 

 begins quite at the base. On the front pair of legs the femora 

 are darker than on those of the others. The distal end of the 

 tibiae and metatarsi are also rather darker. 



The male palp is of the same pattern as that of J. auripes 

 L. Koch, but the epiphysis is not serrated, nor are the bristly hairs
