Metatarsus IV longer than patella and tibia coml^incd. Tibia I witli 4 

 ventral pairs of spines. ? palpal claw with 1 small tooth. 



Comparisons. — ^This species comes very close to Lycosa {Pardoso] 

 flavipes Keyserhng, and appears to differ from it mainly in that the 

 leg IV is not longer than I by double the length of metatarsus TV. 

 Compare also P. minima. 



The Texas specimens are lighter than the northern ones, and the 

 venter is often without black markings. 



Genus SOSIPPUS Simon, 1888. ' 



The North American species of this genus described by Simon (S. 

 floridamis) has not been seen by me. The posterior spinnerets are 

 longer than the anterior, with the apical joint as long or almost as 

 long as the basal and garnished with fusules on its inner siu'face; the 

 labium is longer than wide and quite one-half the length of the maxillce ; 

 the posterior margin of the chelicera has 4 teeth. The face is vertical 

 only in the plane of the anterior eyes. The legs are long, the anterior 

 tarsi and metatarsi usually scopulated. metatarsus 1\ as long as the 

 patella and tibia combined. First row of eyes broader than the second, 

 the lateral eyes as large or larger than the middle ones. The integu- 

 ment is covered with plumed hairs. The sides of the head are nearly 

 vertical. 



Evidently this genus is most closely allied to Pirata. Thev spin a 

 large web like that of an Agalena. 



Genus LYCOSA Latreille, 1804 (ad partem). 



I have followed Simon (1898) in defining this genus, except that I 

 have excluded from it Pirata and Trochosa. 



The main characters are the following : The cephalothorax is highest 

 in the cephalic portion (except in the d^ of charonoides) , and the sides 

 of the head usually only moderately oblique; the first eye row is 

 shorter than the second (except in inhonesta and in the cJ^ of charo- 

 noides) ; the eyes of the second row are never separated by more than 

 1.5 times their diameter; the chelicera are robust and their length is 

 usually quite twice the height of the head in front (except in the Pardo- 

 soid species hilineata, relucens and ocreata) ; the posterior spinnerets 

 are shorter, or but little longer, than the anterior (antelucana, mccooki. 

 scutulata) ; tibia I has 3 pairs of ventral spines ; the labium is shorter 

 than one-half the length of the maxillse, but longer than wide (except 

 in hilineata and scutulata) ; metatarsus IV is shorter than the patella 

 and tibia combined (except in the c? of scutulata, antelucana and 

 ocreata^. The length of the dorsal eye area to the cephalothorax
