1904.] NATURAL SCIENCES OF PHILADELPHIA. 305 



Habits. — A common species in the vicinity of Austin, mider stones 

 on dry hillsides. 



Trochosa purcelli (Montg.). 



Lycosa purcelli Montg., 1902. 

 Lycosa kochii Keys., Emerton, 1885. 

 nee Tarentula kochii Keys., 1876. 

 Lycosa nigraurata Montgomery, 1902. 



(Several specimens from Pennsylvania, New Jersey and Massachu- 

 setts.) 



Eyes (9). — First row slightly shorter than the second, nearer the 

 clypeal margin than to the second row, about straight or lateral eyes 

 slightly lower, middle eyes 1.5 times the size of the lateral. Eyes of 

 second row largest, slightly more than their diameter apart. Dorsal 

 eye area to cephalothorax as 1 : 4.75. Quadrilateral of the posterior 

 eyes broader than long. 



Foryn (9). — Cephalothorax highest at about the middle, in front 

 truncated and not quite one-half its greatest transverse diameter, the 

 sides of the head oblique. Chelicera with 3 pairs of teeth, longer than 

 the width of the clypeus, their length 2.25 times the height of the head 

 in front. Labium longer than broad, shghtly concave apically, not 

 one-half the length of the maxillae. Sternum rounded. Leg. IV to 

 cephalothorax as 3.5 : 1. Metatarsus IV shorter than patella and 

 tibia combined. Spinnerets about equal in length. Palpal claw with 

 4 teeth. 



Remarks. — In addition to certain shght differences in the form of the 

 epigyna (mentioned in my preceding paper), this form is to be separated 

 from kochii in that the cephalothorax in front is less than one-half its 

 greatest transverse diameter, instead of "vorn bedeutend mehr als 

 halb so breit als in der Mitte," and in being highest at or behind the 

 middle. The male which I had described as a new species {nigrau- 

 rata) is an unusually bright-colored individual, with 4 teeth on the 

 posterior margin of one of the chelicera.
