Superfamily Argiopoidea 



Male with the embolus evenly curved, not 

 elbowed, and with the terminal apophysis 

 of the bulb of the palpus not conspicuously 

 elevated or produced above into a horn-like 

 process extending beyond the front margin 

 of the alveolus. P. 622. Lycosa 



Genus SOSIPPUS (So-sip'pus) 



The anterior eyes are in a strongly procurved row; the lateral 

 eyes are as large as or larger than the median eyes. The lower 

 margin of the furrow of the chelicerae is armed with four teeth. 

 The tarsi and metatarsi of the anterior legs are densely scopulate. 

 The last segment of the hind spinnerets is moderately long and 

 conical. 



This genus is our only representative of a small group of 

 genera, the Hippaseae, which, while possessing the structural 

 characteristics of the Lycosidae, resemble the Agelenidae in habits. 

 They are sedentary, constructing a large permanent funnel-web, 

 upon which they run like an Agelena. 



Two species have been found within the limits of the United 

 States; one in Florida and one in California. 



Sosippus floridanus (S. flor-i-da'nus).— - The female is a 

 large spider measuring nearly three fifths inch in length; and the 

 male measures nearly one half inch in length. The cephalothorax 

 is deep reddish brown or reddish black, with a median stripe of 

 yellow hair behind the eye-region, and on each side a wider 

 marginal white band. The abdomen is blackish above with a 

 row of white spots on each side, and narrow transverse white 

 lines on the hind part. 



This species occurs in Florida. 



Sosippus californicus (S. cal-i-for'ni-cus). — The female meas- 

 ures from one third to two fifths inch in length. It was described 

 from Southern California. 



Genus LYCOSA (Ly-co'sa) 



The labium is longer than wide and the basal excavations 

 in it are long, usually one third or more of the length of the 

 labium (Fig. 716). The face is much wider below than above 

 and has the sides strongly convex. The anterior tibiae are armed
