length of the patella. No teeth on the inferior tarsal claws. Palpal 

 claw with 5 teeth. 



Comparisons. — This is the species identifiecl by Emerton with the 

 European piraticus. But they are distinct, judging from the descrip- 

 tion given by Simon in his Arachnides de France. The structure of the 

 epigyna differs; in marxi the median anterior eyes are but little larger 

 than the lateral (instead of almost double their size) and almost con- 

 tiguous (instead of being separated by a little more than their diam- 

 eter), and further, these median eyes are much nearer each other than 

 to the lateral; in jnarxi also tibia and patella IV combined are longer 

 than the cephalothorax (instead of shorter) ; and there are differences 

 in coloration.

(Four 9 9 , types, York county, Pennsylvania.) 



Eyes. — First row somewhat shorter than the .second, middle eyes 

 slightly higher and a little smaller than the lateral, and nearer each 

 other than to the lateral, equidistant from the clypeal margin and the 

 second row. Eyes of the second row largest, slightly more than their 

 diameter apart. Third row broadest, its eyes about twice their diam- 

 eter behind the second row. Quadrilateral of the posterior eyes as 

 long as broad. Length of dorsal eye area to cephalothorax as 1 : 4.3. 



Forin. — Cephalothorax in front truncated and not quite one-half its 

 greatest transverse diameter, highest at the posterior eyes, sides of 

 head rather steep, head projecting in front of the clypeus. Chelicera 

 with 3 pairs of teeth, their length greater than the width of the clypeus 

 and not quite twice the height of the head in front, nearly straight 

 anteriorly. Labium longer than broad, not one-half the length of 

 the maxillae, widest just behind its middle, rounded apically. Sternum 

 longer than broad. Posterior spinnerets longest (almost twice the 

 length of the anterior). Length of leg IV to cephalothorax as 3.7 : 1; 

 metatarsus IV not quite as long as patella and tibia combined. One 

 tooth on the inferior tarsal claw. 



Comparisons. — ^This species is intermediate between Lycosa and 

 Pirata, resembling the former in the height of the head and the short- 

 ness of the first eye row. 



Pirata nigromaoulatus Montg.

Eyes. — First row almost as broad as the second, equidistant from the
