Color in Life.-Cephalothorax in the ? with a broad butf 

 median band .videst at the middle and extending from the ante- 

 rior eyes backward the whole length of the dorsum, and m it a 

 short very narrow darker line between the posterior eyes and a 

 similar line at the dorsal groove; on each side of this band a broad 

 dark-browu baud, next a narrow buff line, then a submargmal 

 band, composed of a single row of dark-brown spots, finally a 

 narrow buff marginal line. Sternum pale yellow-brown with a 

 darker marking in the form of a closed curve, rounded anteriorly 

 and pointed posteriorlv, the extreme margin of sternum being 

 brownish-black. Abdomen above a grayish-buff, with, on the 

 anterior half, a median browu band pointed behind, there enchng 

 at about the middle, and including a lighter band; to each side of 

 this a rather indistinct brown band extending about to the middle 

 and continued toward the spinnerets as a row of about five black 

 spots with pale spots between them; sides of abdomen a lighter 

 ground color, with numerous short brown stripes pointing caudad 

 and a few dark-brown spots ; venter grayish-white, with two pairs 

 of longitudinal rows of small brown spots converging toward spm- 

 nerets 'the inner rows more pronounced in their anterior portions, 

 the outer rows in their posterior portions. Legs yellowish, darker 

 above, the palpi and maxillce the same color, the chehcera darker, 

 and the labium black. Superior spinnerets pale gray, the mferior 



browu. 



In some females the dark stripes are lacking on the venter. 



The males are very similar in coloration, but darker, particularly 

 on the abdomen, and the tibia of the first leg is densely covered 

 with long black hairs, resembling the arrangement of bristles on 



a test-tube cleaner. ^ , . -o i
