Arachnida from Natal. 201 



In leg-measurements this new species closely resembles 

 H. lineata, Poc. (P. Z. S. 1897, p. 749), but it may be 

 readily distinguished by the construction of the mandibular 

 stridulating-organ, the upper scries of sette being more com- 

 pact and oblique and the lower more isolated from the adja- 

 cent setae of the oral fringe. The male differs both from 

 B. atra, Latr., and H. chrysogaster, Poc, in colouring and 

 shape of palpal bulb.
