44. Epeira Caroli. 



PI. 14, fig. 15. 



Description. Grayish ; cephalothorax black ; abdomen much 

 elongated behind, blackish, with the disc grayish, varied with 

 darker lines ; feet varied with black, particularly the first and 

 second pairs. 



Observations. It is not probable that this can be referred to 

 E. caudata, though that species varies much in shape. 



Habitat. Alabama. September. 



[The body is piceous beneath ; legs arranged 1. 2. 4. 8. It 

 is nocturnal in its habits. Supplement.'] 



Genus Phiixyra. Mihi. 



Characters. Cheliceres very short; maxillai short, parallel, 

 truncated above ; lips subtriangular ; eyes eight, equal, all borne 

 on tubercles, in two rows of four eyes each ; the first nearly 

 straight, placed on the very margin of the cephalothorax, the sec- 

 ond arcuated toivards the first, so that the external eyes are widely 

 separated from those of the first ; feet, the first pair larger and 

 much longer than the rest, the fourth next, than the second, the 

 third being the shortest. 



Habits. Araneides sedentary, making a horizontal web 

 formed of spiral threads, crossed by other threads departing 

 from the centre, and abiding on the web with its leo;s extended 

 in a straight line. Cocoon cylindrical, tapering equally at both 

 ends. 



Remarks. This new subgenus is probably closely related to 

 Uloborus of Latreille. The position of the eyes, however, is 

 reversed, and the legs are different. In several particulars it is 

 related also to Tetragnatha. 



The habits of the spider upon which I have established this 

 new subdivision, are analogous to those of Epeira. Its web, 

 however, is always horizontal. When threatened, it shakes its 

 web violently and thus escapes the notice of its enemies. The
