Superfamily Argiopoidea 



found also in the West and in the South. It occurs among stones 

 along streams and also in hot and dry places. 



Pardosa xerampelina (P. xer-am-pel'i-na). — The cephalo- 

 thorax is deep brown or black above, with a median reddish brown 

 band, which is widest about the median furrow; there are no 

 distinct lateral stripes, but sometimes a few obscure light spots 

 above the margin on each side posteriorly. The abdomen is 

 black above or nearly so; there is a lanceolate basal mark of brown; 

 the basal stripe is joined at two points on each side near its apex 

 by the ends of a V-shaped mark, the apex of which is directed 

 laterally; on the hinder part there are several, more or less distinct 

 chevrons. The epigynum of the female (Fig. 731, a) differs from 

 that of our other species it being widest in front. The female 

 measures one third inch in length; the male is smaller. 



This is a Northern species which occurs especially in moun- 

 tainous regions. 



Pardosa grcclandica (P. grcen-land'i-ca). — The cephalothorax 

 is black or nearly so, with a lighter, brown, median band beginning 

 only a little in front of the dorsal furrow and narrowing to a line 

 on the posterior declivity of the carapace; from the front of the 

 median band a horn-shaped yellow mark extends outward and 

 forward on each side toward the corresponding eye; these marks 

 are sometimes obscure or absent; there is a row of three or four 

 curved light marks above the margin on each side. The abdomen 

 is covered above with brown hair, with bunches of white hair 

 forming a row of white spots along each side. The form of the 

 epigynum is shown in Fig. 731, c. The female measures a little 

 more than four tenths of an inch; the male, a little less. 



This species was first described from Greenland; but its range 

 extends south to the White Mountains and to Colorado and Utah. 

 In Oregon and Washington it is the dominant species of Lycosa. 



Pardosa modica (P. mod'i-ca). — The cephalothorax is dark 

 brown, with a reddish brown median stripe, which is widest just 

 behind the third row of eyes, constricted at the front end of the 

 dorsal groove, and again immediately behind it; this stripe is 

 divided in front of the groove by a dark middle line, widest in 

 front and extending back as far as the dorsal groove; there is a 

 light stripe on each side extending under the eyes to the clypeus. 

 The abdomen is brownish black above, with a reddish brown basal 

 lanceolate stripe, and a series of more or less distinct chevrons
