Plate 1, figs. 2-5. 



Male. — Carapace dusky brown, the sternum darker. Legs in gen- 

 eral yellow, the joints of the anterior pairs dusky or blackish at 

 distal ends, particularly in the case of the femora and tibiae of the 

 first pair. Abdomen above with a median longitudinal dusky or 

 blackish stripe which continues down caudal end to spinnerets, broad- 

 ening caudad; on each side of this stripe shining silver-colored. 

 Sides and venter in front of the silvery area from dorsum dark, 

 brown and blackish. 



Cephalothorax with a straight process from clypeus, which is 

 thicker at base than distally, where it is rounded. Just above the 

 clypeal process the head is extended in a process which is slender 

 at base and expands distally into a rounded, knoblike form, this 

 end resting against the upper surface of the end of the clypeal 

 process (pi. 1, figs. 2, 3). This clavate upper process bears the 

 median eyes, of which the anterior are much more widely separated 

 than the posterior, the latter being more than the diameter of an eye 

 apart. 



Abdomen with the dorsal line in profile nearly horizontal; the 

 spinnerets lx)rn directly below; the caudal end rounded (pi. 1, 

 fig. 4).
