yellow bands being blackish. Sternum deep black, frequently with a 

 median yellow band on its anterior half. Abdomen above intricately 

 but distinctly patterned with black and greenish-yellow, as follows : on 

 the anterior half of the dorsum is a broad median band, ending bluntly 

 at the middle, yellow anteriorly and brown posteriorly and containing 

 in its anterior portion a pair of short black stripes; behind this 

 band are groups of small black dots on a yellow ground, the more pos- 

 terior of them tending to form ill-defined transverse rows. The sides 

 are yellow with black dots. The venter gray or yellow, blackish 

 aromid the epigynum, sometimes with a narrow median blackish line 

 that occasionally widens to form a spot in front of the spinnerets.

Comparisons. — This species comes closest to lapidicina Em., but is 

 separable from it on account of the following characters : The posterior 

 transverse plate of the epigynum is always much narrower, and the 

 (5^ palpal organ with a large tooth not present in lapidicina; smaller 

 absolute size, while the length of the legs is proportionately greater; 

 the lighter coloring of the dorsal surface and the different abdominal 

 pattern. 



Habits. — The most abundant Lycosid in the vicinity of Austin, 

 diurnal, and running with great swiftness. Usually found close to 

 water.
