the thorax blackish. Sternum yellowish or reddish-brown, darker than 

 the coxae. Ahdomen above deep browm or reddish-brown, on its an- 

 terior half a slightly darker median band which is widest at its anterior 

 end, has a pair of short lateral diverticula at its middle, and terminates 

 posteriorly in a transverse arc. On the posterior dorsum is a series 

 of four transverse arches, which become posteriorly successively smaller, 

 each in its anterior portion of the same color as the median band, 

 but posteriorly narrowly edged with whitish. At each antero-lateral 

 margin of the dorsum is a black mark of a U-shape, with the bend of 

 the U directed medio-anteriorly, and on a line with each of these marks 

 a row of four to six black spots which extend on each side of the dorsum 

 back to the spinnerets; the first two of these spots are largest and 

 always the most conspicuous, and sometimes all the spots of one line 

 are connected so as to form a broken, longitudinal black line. The 

 sides are deep brown mottled with spots of the same color as the me- 

 dian band. The venter has a band of yellowish extending from the epi- 

 gastric slit to the spinnerets, which is in front almost as broad as the 

 lung area but behind becomes slightly narrower; within this light 

 band are two parallel longitudinal rows of small blackish spots, most 

 distinct on the anterior half of the venter, and never extending back 

 quite as far as the spinnerets. Epigynum deep reddish-brown. Spin- 

 nerets chocolate-brown. Chelicera deep reddish-browTi or black, with 

 black and white hairs, the macula pale red; maxiUcv and labium lighter 

 with yellowish tips. Legs distinctly banded above, less distinctly 

 lielow, with black and buff on the femora, patellae blackish proximally 

 and buff distally, tibiae blackish at the ends and buff at the middle, 

 tarsi and metatarsi blackish.

 eyes higher and larger than the lateral. Eyes of the second row largest 

 in the 9 , slightly more than their diameter apart, not quite in the d'.

 second row. Dorsal eye area less than one-fifth the length of the
