licera yellow like Ihe forehead, maxillce yellow, labium brownish 

 with yellow tip. Legs pale greenish -yellow, with indistinct annu- 

 lations. Palpi colored like the legs. 



Comparisons. — This species is very similar to P. nigropalpis ; the 

 differences in the copulatory organs of the two are slight, but scita is 

 much lighter colored, is smaller, and the cephalothorax relatively 

 wider and shorter. 



It also closely resembles P. pallida Emerton, but differs from it 

 in the epigynum and in the coloration (e.g., the shape of the median 

 cephalothoracic stripe, and the coloration of the abdominal venter).

 row widest, its eyes also on brownish prominences and placed closer 

 to the second row than to each other. All eyes relatively large and 

 of a light color. Dorsal eye area a little less than one -quarter the

Form. — Cephalothorax in front fully one-half its greatest trans- 

 verse diameter, highest just behind the middle. Head rather low 

 in front, its sides moderately oblique. Length of chelicera about 

 1^ times the height of the head in front. Sternum nearly as broad 

 as long. Legs rather slender, with moderately long spines and few
