Apparently this species is close to L. piratica. The palpal organs are 

 similar, but in jebricu'.osa the superior horn of the apophysis is at once 

 seen to be longer and straighter and more outwardly directed. 



Pirata piratica (Clerck) var. utahensis, new. 



Male. — Palpal organ agreeing in detail with that of the European 

 species or nearly so. 



Cephalothorax with the median pale stripe and dark 'S^-shaped 

 enclosure as usual, the arms of the latter parallel anteriorly back to 

 posterior third, then converging to a point. Laterial pale stripes 

 reaching pars cephalica, each bordered below wdth a dark marginal 

 stripe. A marginal line of bright white hair showing in life or in dry 

 specimen as in jebriculosa and piratica of type fomi. Femora of all 

 legs with dark annuli, these most distinct on second and third pairs, 

 showing clearly on the ventral surface of the latter; other joints 

 unmarked, distal ones some darker. Sternum and coxce beneath pale. 

 Abdomen black above, the usual pale mark at base; a white stripe of 

 hair over each antero-lateral angle ; a narrower line of white hair each 

 side of basal mark, followed behind by a row of white spots similarly 

 formed; venter pale, with three narrow stripes of brown converging 

 caudally.

Likely to be found throughout the Pacific States.
