Superfamily Argiopoidea 



Genus ZORA (Zo'ra) 



The tibiae and metatarsi of the anterior legs are armed 

 below with many very long spines and a few elevated ones; the 

 apical segment of the hind spinnerets is short and indistinct; 

 the posterior row of eyes is strongly recurved. 



Zora includes small spiders with a yellow or whitish integu- 

 ment ornamented with longitudinal bands or with small spots 

 usually in series; their legs are thick, the two first pairs are often 

 in part black or brown. They live in moss and detritus; they 

 only rarely climb on plants, and they spin neither a tube nor 

 a web. (Simon.) 



Only one species is reported from this 

 country. 



Zora pumilus (Z. pu'mi-lus). — 1 have not 

 seen this species and can only copy the de- 

 scription and figure given by Hentz, who first 

 described it; no later description of it has been 

 published. In that part of the figure (Fig. 

 651) showing the arrangement of the eyes, the 

 posterior row is the upper one: 



"Livid, testaceous; cephalothorax with 

 two longitudinal bands near the middle, and 

 two curved fillets near the edge, fuscous; 

 abdomen with a line bifurcated anteriorly on 

 the middle, and two lines of minute dots on the 

 sides, fuscous; same colour underneath, with minute fuscous dots. " 



This is the Katadysas pumilus of Hentz. It was found by 

 him under stones in North Alabama.

(after Hentz) 



Genus CHEMMIS (Chem'mis) 



The tarsi of all of the legs are lightly scopulate; and all 

 are furnished with tufts of terminal tenent hairs. There are five 

 pairs of spines beneath the tibia of the first legs. The posterior 

 row of eyes is slightly procurved. There is a conical chitinous 

 cusp in front of the spinnerets. 



Only a single species of this genus has been found in the 

 United States; this was described from Arizona. Another species 

 is known from Central America.
