Superfamily Argiopoidea 



Genus CUPIENNIUS (Cu-pi-en'ni-us) 



This genus is distinguished from the other genera of the 

 Ctenidae by the presence of a third tarsal claw in addition to the 

 tufts of terminal tenent hairs. Figure 626 represents the tip of 

 the tarsus, with one of the two tufts of 

 terminal tenent hairs removed so as to expose 

 the third claw. 



Cupiennius sallei (C. sall'e-i). — This is a 

 Central American species which has been found 

 in Florida, and is the only representative of the 

 genus reported from the United States. It is 

 a large spider, measuring from one inch to one

Family CLUBIONIDjE (Clu-bi-on'i-dae) 



The Clubionids (Clu-bi-on'ids) 



This family includes 

 spiders that live in flat 

 tubular nests on plants, 

 usually in rolled leaves, 

 and others that live on 

 the ground, under stones 

 or rubbish or in moss. 

 As in the Thomisidaeand 

 I leteropodidae, these spi- 

 ders have eight eyes ar- 

 ranged in two rows, and 

 have only two tarsal 

 claws. They differ from 

 both of these families in 

 that the form of the 

 body and the attitude of 

 Fig. 62, pedipalp of trachelas the legs are not those 



characteristic of crab-spiders; and they differ from the Thomi- 

 sidae in that the lower margin of the furrow of the chelicerae is 

 distinct and armed with teeth. From the preceding family, the 

 Ctenidae, thev differ in the arrangement of the eves and in thai
