Drassodes auriculoides n. sp. 



Female: Length 10 mm. Cephalothorax brownish yellow, front 

 of head and mandibles much darker and redder, a dark line around 

 the edge of the cephalothorax. Hairs on the mandibles with a dark 

 spot at the base of each. Legs yellow, these and the cephalothorax 

 covered with a thin down of white hairs among which are some black 

 hairs. Feet with heavy dark scropulae which thin out toward the middle 

 of the metatarsi. Sternum yellow, with a border of heavy brown 

 chitin, truncated in front, widest at second coxae, with a right angle 

 point between the posterior coxa;. Posterior eyes in a straight row, 

 rather far from the front row. P. M. E. rectangular, almost square, 

 close together. (PI. XV, Fig. 4a). Abdomen long and low, widest 

 at the posterior third, narrowing abruptly to an obtuse point. Color 

 of the abdomen under alcohol a light brownish gray, due to the mixture 

 of black and white hairs, a long narrow light-colored basal stripe, 

 becoming dark gray in the miiddle, ends in a series of irregularly placed 

 dark round spots a short distance in front of the tip. Spinnerets, long, 

 yellowish brown, approximately equal. Venter lighter than dorsum, 

 much lighter in front of epigastric furrow. Epigynum brown, consisting 

 of three lobes, the middle nearly square, the side ones each resembling 

 a human ear. (Plate XV, Fig. 4b).

 shiny, as if made of a dark wood showing some brown grains, freshly 

 lacquered. Oval shield on base of abdomen with the same characters,

 of the first legs dark, shining, the others dark before and behind, but
