narrow, curved, yellowish white band near the sides, beneath 

 yellowish on both sides ; feet with a few white hairs, 1. 4. 2. 3. 

 A male. 



Observations. This spider has great affinity with Attus 

 militaris, but is sufficiently distinct. The female probably 

 differs from this in markings, and possibly is among my [20 1] 

 descriptions ; but this can be established only by future ob- 

 servers, who, after all my labors, have still a wide field before 

 them to perfect the history of the spiders of North America. 

 This was communicated to me by Mr. Thomas R. Dutton, 

 a young naturalist of great perseverance, energy, and discrim- 

 ination, who collected it in Georgia. 



[PI. 18, fig. 26, eyes. The mandibles have not so sharp an 

 inner point as A. militaris ; the white band on the eephalotho- 

 rax reaches neither the base nor the front ; the yellowish white 

 band on each side of the abdomen is blackish on the extreme 

 sides ; in the description it is stated that the second joint of the 

 palpi is covered with white hairs ; on the sheet containing the 

 drawing it is stated that it is the first joint which is so charac- 

 terized. Supplement.]
