IsoPEDA TIETZI, nov. sp. (Text-fig. 98.) 



Female. -Cephalothorax red-brown, covered with fine closely- 

 lying yellow hair; mandibles darker red-brown, long yellowish-grey 

 bristles ; lip and maxillee dark red-brown to black-brown ; sternum 

 black-brown, with thick velvety-black hair extending over the 

 COXES. Legs yellow-brown, with dingy yellow hair ; silvery- white 

 below the patella, brown at each end, and silvery- white in middle 

 underneath the tibia of first and second pairs, fainter on third 

 and fourth. Abdomen yellow-brown above and below, a dark 

 stripe behind the genital fold and impressed shield-pattern. 



The mcdes vary from the same colour as the females to lighter 

 yellow-brown and rather lighter mandibles, lip, and maxUlse. In 

 one specimen the eyes are yellow on distinct black rims, in the 

 others all yellow. 



The cephalothorax is moderately high, and rounded some distance 

 from the sides, a deep and long fovea with faint side strise. The 

 front row of eyes is slightly procurved, the side larger than the 

 middle and only half the distance from them that the latter are 

 from one another. The rear row are equidistant, and the distance 

 between front and rear median greater than the diameter of the 

 front median. 



On tibia iii. in the females is one spine above, in the males two 

 on tibia iii. and one on tibia iv.
