Superfamily Argiopoidea 



Jersey, is referred to it by Petrunkevitch ('\oa). The female meas- 

 ures .07 inch in length; the male, .06 inch. A figure of a side view 

 of the New Jersey specimen and of its palpus is given by Petrun- 

 kevitch (Fig. 290). 



Genus GAMASOMORPHA (Ga-mas-o-mor'pha) 



This genus represents that section of the family in which 

 the abdomen is hard. Only one species has been observed in 

 :his country. 



vuimasomorpha Jloridana (G. flor-i-da'na). This is a small 

 spider, measuring only one twelfth inch in length. It is reddish 

 yellow with paler legs. It occurs in Florida. 



Family SCYTODIDS* (Scy-tod'i-dae) 



The Scytodids (Scy-tod'ids) 



The scytodids belong to that portion of the series of six-eyed 

 spiders in which there is only a single tracheal spiracle. They 

 differ from the following family, which also possesses this char- 

 acteristic, by the fact that there is not a distinct suture between 

 the labium and the sternum. The eyes are all pearly white. 



In one of the genera, Plectreurys, there are eight eyes; but the 

 simplicity of the external reproductive organs which is charac- 

 teristic of this series, as well as other family characteristics, 

 distinguishes this genus. 



Four genera are .represented in our fauna; these can be sepa- 

 rated by the following table:
