becoming abruptly a little narrower near posterior end of pars cephalica 

 and then gradually narrowing posteriorly. Tegument of median 

 stripe reddish brown, but quadrangle of posterior eyes often black; 

 median stripe clothed with gray-brown pubescence. Sides of cephalo- 

 thorax darker above and becoming lighter below; clothed with gray- 

 brown pubescence, like that of dorsal stripe, mixed with dark blackish 

 pubescence, the brown hair becoming gradually more abundant from 

 above below but forming no distinct marginal bands. Chelicercc dark 

 red -brown with short light brown pubescence basally and darker longer 

 hairs on distal part. Endites reddish brown, light at tips. Labium 

 darker, blackish, also lighter distally. Sternum dark brown, marked 

 by a faint paler median line, clothed with brownish-gray pubescence and 

 longer black bristles. Coxce of legs beneath a little lighter than 

 sternum. Legs clear brown, entirely unmarked or, more rarely, with 

 indistinct annular markings on femora. Palpi similarly colored. 

 Abdomen with brown-gray, brown and black hair; venter pale, immacu- 

 late; sides above finely streaked and spotted with the darker puljescence 

 among the paler. Anterior face of abdomen with a black transverse 

 band extending over each antero-lateral angle. At base a lanceolate 

 outline, sometimes absent, which behind gives off a number of lines on 

 each caudo-laterally, and is followed behind by a series of chevron- 

 formed lines; in most on each side of dorsum a row of dark angular 

 marks in which the ends of the chevron-lines terminate. Spinnerets 

 brown, densely pubescent. Epigynwn dark reddish brown. 



Cephalothorax highest at posterior eyes, moderately low behind, a 

 little concavated at dorsal groove. Face in height less than half the 

 length -of the chelicerse, its sides convex and widely slanting. 



Anterior row of eyes as long as second, gently procurved; anterior 

 median eyes more than their radius apart, about half as far from the 

 smaller lateral eyes; anterior lateral eyes about their diameter from 

 front margin of clypeus, farther from eyes of second row. Eyes of 

 second row separated by three-fourths their diameter or a little more. 

 . Eyes of the third row once and a half again as far from each other as 

 from the eyes of the second row. Quadrangle of posterior eyes about 

 one-fifth the length of the cephalotliorax. 



Lower margin of furrow of chelicerce armed with two equal stout teeth, 

 the upper margin with three as usual. Labium as wide as long; basal 

 excavation less than one-third the total length (1 : 3.6) ; rather strongly 

 attenuated in front with sides above straight or slightly concave below 

 angles; anterior margin indented at middle but sides a little convex.
