Superfamily Argiopoidea 



and the black margin there is a series of more or less distinct black 

 spots (Fig. 394, male; Fig. 395, female), the abdomen is white 



mottled with black or 

 dark gray. The length 

 of the body is one eighth 

 inch. 



In its habits this 

 species differs greatly 

 from the more typical 

 sheet-web weavers, 

 for so far as has been 

 observed, it makes no 

 web. It is found under 

 leaves on the ground 

 and on the trunks of 

 trees, where it pursues 

 its prey. Its colour and 

 markings are protective, 

 resembling that of bark 

 and lichens. Our adult

Genus TROGLOHYPHANTES , 

 (Trog-lo-hy-phan'tes) 



These are cave-inhabiting 

 spiders, which, however, are not 

 blind. Their eyes are greatly 

 reduced in size, especially the an- 

 terior median eyes; these in some 

 specimens appear to be want 

 ing. In this genus, as in Antb 

 robia and Pbanetta, the pedipalps 

 of the female have no tarsal claws. 

 The presence of eyes distin- 

 guishes this genus from Antb- 

 robia; and it differs from Pbanetta 

 in the arrangement of the eyes, the posterior median eyes being 

 much closer together than to the posterior lateral eyes, and the
