brownish- black, and au indistinct broad, paler marginal band 

 becomes apparent on the thorax. 



Comparisons. — Cf. L. sepulchralis n. sp. 

 7. Lycosa stonei u. sp. (PI. XXIX, figs. 9, 10.) 



(Types of d and 9 in author's collection, from Philadelphia; 

 numerous specimens from Philadelphia and its vicinity, and from 

 AVest Chester, Pa.) 



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

 higher than the lateral. Eyes of second row largest, a little more 

 than their diameter apart. Third row widest, its eyes nearly equi- 

 distant from each other and from the second row. Dorsal eye area 

 nearly one-quarter the length of the cephalothorax. 



Form. — Chelicera fully 1^ times as long as the head is high in 

 front. Sternum longer than wide, rather pointed behind. Supe- 

 rior spinnerets longer than the inferior. Legs long and slender, 

 with short hairs and long spines. Labium barely half the length 

 of the maxillse and rather conically pointed at its distal end. 

 Cephalothorax narrow, in front less than half its greatest trans- 

 vei-se diameter, highest at third pair of eyes. Sides of head steep. 



Dimensions. — Length of cephalothorax, c?, 3.1. mm.; ?, 

 3.1 mm. 



Length of abdomen, d, 3 mm. ; 2, 3.5 mm. 



Length of first leg, c?, 12.3 mm. ; ?, 10.1 mm. 



Length of second leg, d, H mm. ; ?, 9.8 mm. 



Length of third leg, d, 10.5 mm. ; 9, 9 mm. 



Length of fourth leg, cf, 14.5 mm. ; 9, 14 mm. 



An unusually large 9 has a total length of 9.5 mm. 



d. Color in Life. — Cephalothorax above glistening black, a 

 median gray stripe (composed of long gray hairs which readily 

 rub off) commencing anteriorly between the posterior eyes, where 

 its width equals the distance between these eyes, and extending 

 backward, usually with more or less of a middle constriction, to 

 the posterior end of the thorax, where it is somewhat narrower ; a 

 few similar light hairs around the middle eyes, and a narrow line 

 of them at the extreme margin of the thorax. Sternum deep 

 black with a narrow marginal line of short gray hairs. Abdomen 

 above black with a broad median band, almost the width of the 

 dorsum and broader than the thoracal band, composed of long gray- 

 i.--h hairs and extending to the spinnerets; sides black; venter black
