Superfamily Argiopoidea 



a very few spines. The scape of the epigynum is short and 

 broad and is directed backward (Fig. 546). The epigynum of 

 Acacesia closely resembles that of Neoscona, but the scape lacks 

 the lateral tubercles, and the openings of the spermathecae are 

 exposed in the atriolum, whereas in Neoscona they are in the 

 dorsal wall at the base of the scape. The tibia? of the second legs 

 of the male are somewhat thickened and are strongly spined, 

 but the spines are not arranged in a series (Fig. 547); the 

 anterior coxae of the male are furnished with apical teeth. 



The following species, though not common, is distributed 

 over nearly the whole of North America. 



Acacesia joliata (A. fol-i-a'ta). — The female is one fourth 

 inch in length; it is easily recognized by the very distinctive 

 markings of the abdomen (Fig. 548); the male is a little smaller 

 but resembles the female in colour and markings. 



Genus EUSTALA (Eu'sta-la) 



This genus resembles Acacesia in the arrangement of the eyes; 

 but differs in that the legs are armed with many spines. The
