Superfamily Argiopoidea 



shorter than the basal segment; in having the labium nearly 

 always as wide as or wider than long; and in having the posterior 

 coxae, as a rule, well separated. In this genus the clypeus is 

 much wider than the anterior lateral eyes, and the anterior 

 median eyes are as a rule not much smaller than the lateral eyes. 

 All of the eyes are present. 



The species are small, our more common ones measuring 

 from one fifth to one fourth inch in length. They are most 

 often found under dead leaves in 

 woods. Simon states that they 

 spin delicate horizontal webs 

 under stones or in the midst of 

 moss; and that the eggs are en-

closed in a little white sac, which 

 is covered with bits of earth. 



Nearly a dozen species have 

 been described from our fauna. 



Cicurina arcuata (C. ar-cu-a'ta).— - This is our most common 

 species. It measures from one fifth to one quarter of an inch in 

 length. The colour is pale yellowish brown, lighter on the abdo- 

 men, which bears [faint gray markings. Figure 678 represents 

 the epigynum of the female, and Fig. 679 the palpus of the male. 



Genus CHORIZOMMA (Cho-ri-zom'ma) 



The spiders of this genus are closely allied to Cicurina but 

 differ in the possession of only six eyes. One species is found 

 in California and one in Lower California. 



Choriiomma californica (C. cal-i-for'ni-ca). — Only the male 

 of this species has been described. This sex measures one fifth
