Comparisons. — There are two of Hentz's species which may be 

 referred with considerable uucerlaiuty to this oue, namely leiita and 

 erratica ; but in my oi)iuiou his figures, and still more his descrip- 

 tions, give too inadequate a diagnosis (compare Banks, 1891). 

 18. Lycosa nigraurata n. sp. (PI. XXX, fig. 53.) 



(1 c?, type, jNIedford, Burlington county, N. J., Stone Coll.) 



Eyes. — First row shorter than the second, straight, its middle 

 eyes slightly larger. Eyes of second row fully their diameter 

 apart. Third row broadest, its eyes largest and considerably nearer 

 the second row than each other. Dorsal eye area less than one- 

 sixth the length of the cephalothorax. 



Form. — Cephalothorax in front not quite one-half its greatest 

 transverse diameter, highest behind the middle, rather low and flat. 

 Sides of head rather oblique. Chelicera about twice the length of 

 the height of the head in front. Sternum distinctly longer than 

 broad. Legs rather stout.

Length of abdomen, 5.3 mm. 



Length of first leg, 18 mm. 



Length of second leg, 16.6 mm. 



Length of third leg, 16 mm.

Color in Alcohol. — Cephalothorax v/ith a dull orange, broad 

 median stripe extending from the second row of eyes to the poste- 

 rior end of the thorax, constricted slightly just anterior to dorsal 

 groove, widest around and narrowed behind this groove, and contain- 

 ing anteriorly a pair of elongate black spots ; on each side of this 

 median band a black stripe extending from the posterior eye to the 

 €nd of the thorax, narrowest anteriorly and its greater diameter 

 not equaling that of the median band ; a broad submarginal baud 

 of dull orange, interrupted by bauds of black radiating from the 

 black stripe; extreme margin of thorax with alternating orange 

 and black ; forehead dull orange, a large black spot at the ventral 

 margin of each side of the head. Sternum pale yellowish-brown 

 with a narrow blackish margin. Abdomen above dark yellowish- 

 brown, a deep black band arises at each antero-lateral margin and 

 is continued back to about the middle, and behind each of these
