approximately 55% of specimens. Median septum extending anteri- 
ad approximately one-half length of epigynum; hood continuing 
posteriad at sides where it defines a raised, tapered median area 
(Fig. 58); copulatory tubes short, slender, with distinct lateral 
swellings (Fig. 59). 
Diagnosis. Specimens of P. saxatilis most resemble those of P. 
atlantica and P. parvula but differ in having the dorsal cover of 
reflective white setae restricted to the palpal patella. Females are not 
distinguishable from those of atlantica or parvula except geo- 
graphically (see map 3). 
Range. Nebraska and Minnesota to Nova Scotia, south to 
northern Alabama and North Carolina. No specimens were 
available from the type locality of P. saxatilis, i.e., northern 
Alabama, for this study. Thorough collecting there would help to 
confirm our position regarding the identity of this species. 
Natural History. Males have been collected in March, May to 
September, and November, and females May to September. 
Females with egg sacs were taken in June, July, and September. The 
usual habitats are grassy fields or meadows but a few specimens also 
come from marshes, bogs, deciduous woods, or sandy beaches. 
Wolff (1981) gives life history and related data in Michigan.
