282 PKOCEEDIN-GS OF THE ACADEMY OF [March. 



Comparisons. — This species comes closest to L. euepigynatq, but 

 differs from it in shghtly shorter relative length of legs, in greater rela- 

 tive width of cephalothorax (in insopita less than one-quarter longer 

 than broad, in eucpigynata decidedly more than one-ciiiarter), in the 

 dark coloration of the venter, and in the structure of the genitalia. 

 It differs also from L. purcelli, the epigynum of which is very similar, 

 in the slightly greater relative length of the legs, in greater size, and 

 markedly in the coloration. 



Habits. — Less abvuidant than the preceding, and found in drier 

 localities. They live under stones, where the female makes a shallow 

 horizontal burrow lined with silk. 

 Lycosa antelucana n. sp. Pi. XVIII, figs. 5, 6. 



(Numerous specimens from Austin, Texas.) 



Eyes. — First row almost upon the clypeal margin, shorter than the 

 second (but middle points of its lateral eyes as far lateral as middle 

 points of eyes of the second row), its eyes equidistant, with the middle 

 eyes decidedly larger and slightly higher than the lateral. Eyes of 

 second row largest, almost or wholly their diameter apart. Third 

 row little broader than the second, its eyes about 1.5 their diameter 

 behind that row. Dorsal eye area about one-fifth the length of the 

 cephalothorax. Quadrilateral of the posterior eyes nearly as long as 

 broad. 



Form. — Cephalothorax slender, in front truncated in cT' and some- 

 what rounded in ? , fully one-half its greatest transverse diameter (?) 

 or less {o'), highest at the posterior eyes with the sides of the head 

 steep. Chelicera fully 2.3 times the height of the head in front, in the 

 ? shorter than the width of the clypeus, with 3 pairs of teeth. Ster- 

 num longer than broad. Labium longer than broad, less than one-half 

 the length of the maxillae, apically truncated, d^ ]jalpal organ rela- 

 tively small. Posterior spinnerets slightly longer than the anterior. 

 Length of leg IV to cephalothorax, c? 4.1 : 1, Q 3.2 : 1. In the d", 

 but not the 9 , the metatarsus IV is slightly longer than the patella 

 and tibia combined. ? palpal claw with 4 teeth.
