Superfamily Argiopoidea 



Males 



A. Scopus (i. e. the median apophysis of the bulb of the palpus) 



short and stout, not at all or but slightly longer than 



broad. 



B. Anterior depressed lobe of bulb separated into two 



furrows by an elevated narrow fold extending from 



above obliquely downward and outward, externally 



from its lower end are two hooked tentacula, and at 



the corner opposite its upper end a lamellate, indexed 



chitinous angle (Fig. 732, a). P. 655. P. lapidicina 



BB. Not so. 



C. Embolus extending across bulb almost to outer side 



of alveolus (Fig. 732, b). P. 656. P. modica 



CC. Apex of embolus scarcely extending beyond scopus. 



P. 656. P. grccnlandica 



AA. Scopus several times longer than broad. 



B. Scopus extending obliquely forward and outward quite 

 to or some distance beyond margin of alveolus. 

 C. Scopus curving forward with convexity external and 

 apex directed forward. P. 657. P. emertoni 



CC. Not so. 



D. Embolus strongly bent into an S-shape; scopal 

 spur turned forward at apex (Fig. 732, c). P. 655. 



P. stcrnalis 



DD. Embolus but little curved, extending nearly straight 



transversely; scopal spur turned backward at apex 



(Fig. 732, d). P. 653. P. saxatilis 



BB. Not so (Fig. 732, e). P. 654. P. milvina 



THE MORE COMMON SPECIES OF PARDOSA 



The following notes are merely supplementary to the data 

 given in the above tables, which should be used for the separation 

 of species. 



Pardosa saxatilis (P. sax-at'i-lis).— The length of the body 

 is about one fifth inch. The cephalothorax is deep brown or black, 

 with a median reddish yellow band, which is stronglx notched on 

 each side midway between the eyes and the median furrow, 

 and narrowed behind the furrow; there is also on each side a 

 yellow stripe near the margin of the carapace; these stripes are
