both ends of tibia black, these dark bands covered with dark brown 

 hair; the scopuloe of same brown color, but legs elsewhere clothed with 

 much lighter hair which is light brownish gray to whitish. Abdomen 

 with the tegument light brown; at base a dark or blackish median 

 stripe which bifurcates at its caudal end and sends out from its sides 

 several pairs of pointed lines directed caudo-laterally; behind the 

 basal stripe a series of chevron-shaped laterally and anteriorly acutely 

 pointed dark cross-marks, often a series of light dots along each side; 

 doi-sum densely covered above with long brown to grayish-brown 

 pubescence, except over the dark marks which are clothed and made 

 more distinct by black hair; sides of abdomen above dark with brown 

 and black pubescence intermixed in spots and streaks, the sides below 

 becoming paler, yellow to gray or almost white with larger but more 

 sparse black spots; venter nearly always deep brown or black, due 

 largely to the pubescence being very dense and of the latter color; 

 sometimes a light mark or spot within the light area on each side of 

 middle line, leaving three black stripes converging and uniting in front 

 of the spinnerets and united by a cross-bar behind the genital furrow, 

 while in other rarer cases the reduction of the black may be carried 

 even farther. Spinnerets brown. Epigynum reddish black. 



Face in height moderate, more than half the length of the chelicerae ; 

 sides strongly- convex and moderately slanting outward below, not so 

 steep as in scutulata. 



Anterior row of eyes nearly as long as the second, but little procurved ; 

 anterior median eyes not fully their- radius apart, a little farther from 

 the lateral eyes which are a little smaller; clypeus wide, the anterior 

 lateral eyes more than one and one-half times their diameter, or rather 

 nearer twice from its front margin, closer to eyes of second row; eyes 

 of second row not proportionately large, not much less than their 

 diameter apart; eyes of third row twice as far apart as from those of 

 second row; quadrangle of posterior eyes relatively short, being not 

 fully one-sixth the length of the cephalothorax, 



Chelicerce long and very robust, the margins of its furrows armed in 

 typical manner. Labium a little longer than wide (12.5 : 11.75); 

 basal excavation one-third or a little more the total length; labium 

 above excavations broadly rectangular, as wide above as below, the 

 sides nearly parallel and scarcely curved, antero-lateral angles rounded ; 

 front margin widely truncate. Legs long and robust; tibia -f- patella 

 IV shorter than the cephalothorax, of same length or nearly so as 

 tibia + patella I; spines of anterior tibiae beneath as usual; patella I 

 and II each armed on the anterior side with a single spine ; anterior tarsi
