their diameter apart. Eyes of the third row nearly as large as those 

 of the second. Dorsal eye area to the cephalothorax as 1 : 6. 



Form. — Cephalothorax highest a little anterior to the middle, in 

 front truncated and about one-half its greatest transverse diameter, 

 the sides of the head rather oblique. Chelicera about as long as the 

 width of the clypeus, fully 2.5 times the height of the head in front, 

 with 4 teeth on the inferior and 3 on the anterior margin. Labium 

 longer than wide, truncated apically, one-half the length of the maxillae. 

 Maxilla indented on the inferior surface near the distal end. Sternum 

 longer than broad. Spinnerets equal. Leg IV to cephalothorax as 

 3.6 : 1 ; metatarsus IV shorter than patella and tibia combined. 

 Palpal claw with 4 teeth. 



Troohosa avara Keyserling. PI. XX, fig. 42. 



Trochosa avara Keys., 1876. 



Lycosa avara (Keys.), Montgomery, 1903. 



(One Q from Philadelphia; numerous individuals of both sexes from 

 Austin, Texas.) 



Eyes. — First row slightly narrower than the second, straight, equi- 

 distant from the second row and the clypeal margin, the middle eyes 

 closely approximated and fully L5 the size of the lateral. Eyes of 

 second row largest, fully (c?) or almost (9) their diameter apart. 

 Dorsal eye area to cephalothorax as 1 : 6. Quadrilateral of the pos- 

 terior eyes longer than broad. 



Form. — Cephalothorax highest behind the middle, in front truncated 

 and one-half (?) or less (cJ^) as wide as its greatest transverse diam- 

 eter, the sides of the head oblique. Chelicera longer than the width of 

 the clypeus, their length fully three times the height of the head in 

 front, with 3 pairs of teeth. Labium longer than broad, truncated 

 apically, not one-half the length of the maxillae. Sternum longer than 

 broad. Anterior spinnerets longest. Leg IV to cephalothorax ( $ ) 

 as 3 : 1; metatarsus IV shorter than patella and tibia combined. 9 

 palp with 5 teeth. 



Remarks. — The Texas specimens agree essentially with Keyserling's 

 description except in the following points : The epigynum is distinctly 

 broader than long. The abdomen above has a more or less dis- 

 tinct median darker band edged with yellowish on the anterior 

 half, and a pair of white spots on the posterior half, the rest 

 of the anterior surface being finely mottled with black and brown; 

 on the posterior dorsum are narrow transverse stripes of brown, be- 

 tween each two of which is a pair of black spots (each surrounded by 

 a brown ring) ; the venter is pale brown with minute black spots.
