behind the middle, posterior dechvity very steep, clypeus obliquely 

 inclined. Chelicera with 4 teeth on the inferior margin. Sternum 

 longer than broad, rounded. Labium slightly longer than broad, 

 truncated straight apically, widest a little behind its middle. Relative 

 length of legs IV, II, I, III, III only shghtly shorter than I and 11, all 

 rather stout and scopulated; length of leg IV to cephalothorax as 

 4.3 : 1. 



Remarks. — The Texas specimens are larger than the northern ones, 

 and the femora are more or less banded above wdth brownish. 



Habits. — Very abundant at Austin, under the stones close to streams. 

 Females with cocoons are most abundant in the fall. An adult male 

 was found in November, and numerous nearly full-grown males in 

 January.

(Specimens from Pennsylvania and North Carolina.) 

 Eyes. — As in urinator. 



Form. — The general form of the 9 , proportions of the legs, mouth 

 parts, etc., are as in urinator. The c? differs in having the truncated 

 anterior end of the cephalothorax but little broader than one-fourth 

 its greatest transverse diameter, in the cephalothorax being distinctly 

 highest behind the middle, and in the greater slenderness of the legs, 

 which in order of length are IV, I, II, III. The palpus is longer than 

 ,the cephalothorax, its terminal joint large, the tibia with an elevated 

 lamina on the outer side, this lamina longer than wide and with its 

 free border forming two larger and one smaller tooth, the ventral apical 

 edge of the tibia with two teeth; the proximal dorsal portion of the 

 tarsus has an elongated prominence and a small elevated knob lateral 

 to this.
