Tbe genus Drassus of Walckenaer included tbe greater part of 

 tbe present family DrassidiB, as well as some Agalenidai and Cini- 

 Jlonidm. From tbis, various genera bave been separated from time 

 to time, leaving tbe present Drassus an ill defined group containing 

 species differing greatly among tbemselves and forming several 

 groups, whicb f urtber study will no doubt make it possible to sepa- 

 rate. Tbe only two species wbicb I place in tbis genus belong, one 

 near tbe Eui'opean D. lapidosus and tbe otber near D. troglodytes. 

 In tbese species the cepbalotborax is wider in front and less flattened 

 tban in Gnaphosa and Prosthesima. The eyes are small and sepa- 

 rated by spaces at least as wide as tbeir diameter. Tbe front row is 

 nearly straight. Tbe posterior row is longer, and curved with the 

 lateral eyes lower tban tbe middle. The middle hinder eyes are oval 

 and turned apart toward tbe front, and are nearer together than to 

 the lateral eyes. The mandibles and maxillae are large and stout. 

 Tbe maxillje are widened on both sides bej'ond tbe insertion of tbe 

 palpi, the outer corners are slightly rounded and tbe inner corners 

 slope obliquely toward the lip. PI. iv, fig. 7 a. Tbe lip is about 

 half as long as the maxilhe. The colors are gray and drab with fine 

 short, white or gray hairs, and only faint markings on tbe abdomen. 



Drassus saccatus, new sp. 



Plate IV, figures 7, 7c, Id. 



Tbis is one of tbe most common of our Drassidce. PI. iv, fig. 7. 

 The female grows to be 12""" long, with legs 10""" to I5™"\ The 

 color is light gray sometimes with indistinct transverse dark mark- 

 ings on tbe abdomen. The color of the front part of the bead is a 

 little darker and the feet and mandibles and maxillae are brown. 

 Tbe abdomen is long and slender as in Clubwna. The epigynum is 

 small and has two dark round depressions just in front of the fold, 

 fig. Id. 



Tbe male is smaller and more slender. Tbe male palpi are very 

 long tbe patella, and tibia are together as long as the femur, and all 

 are as long as tbe femur of tbe first legs. The tibia has a small 

 process on tbe outer side, fig. 7c. Tbe tarsus is long and narrow.
