siipramarginal yellow stripe with uneven upper margin, and limited 

 below by a black marginal line; no marginal stripe of white hair. 

 Chelicerce reddish brown. Endites brown, pale distally, the labium 

 in most darker, dusky-brown to blackish. Sternum brown. Coxes 

 of legs beneath yellow. Legs clear yellow, darker distally, entirely 

 without dark rings or markings. Abdomen yellow with markings in 

 black as follows : at base above a lanceolate outline ; along each side of 

 dorsum a wavy or zigzag stripe, the two converging to spinnerets, 

 each united with lanceolate basal mark at its base and again at its 

 middle; the outwardly directed angles of these dark stripes often more 

 or less extended down the sides as narrow lines; along the median line 

 of dorsum behind several short black marks, sides of abdomen antero- 

 ventrally with a dark area composed of a close network of black lines, 

 and postero-dorsally with a number of isolated dark areas formed of 

 similar reticulations, leaving thus in most a clear yellow stripe of 

 varying width curving from the dorso-anterior angle obliquely down- 

 ward and backward between the two darkened areas described ; a row of 

 spots of yellow hair on each side of dorsimi behind; venter with some 

 scattered minute black dots, a few usually just behind the epigynum 

 and more numerous ones in front of spinnerets, the latter usually form- 

 ing two short hues close together which may extend forward to middle 

 or even to the spots behind epigynum, sides and venter clothed with 

 yellow hair. Spinnerets yellow. Epigynum pale brown, reddish 

 marginally, darker caudad. 



Face rather low and wide, sides well rounded and slanting. Cephalo- 

 thorax high ; highest at third eye row, from there convexly rounded to 

 the dorsal groove; posterior declivity steep. 



Anterior row of eyes as wide as the second, nearly straight, the centers 

 of the lateral eyes being but little' lower than those of the median; 

 anterior median eyes a little larger than the lateral, scarcely one-third 

 their diameter apart, their radius from eyes of second row; anterior 

 lateral eyes four-fifths their diameter from front margin of clypeus, the 

 same distance from eyes of second row ; eyes of second row less than 

 their radius apart (2 : 5) ; quadrangle of posterior eyes less than one- 

 fifth as long as cephalothorax (1: 5.5), wider in front than long, very 

 wide behind, being wider than in front in ratio of 8.4: 5.6. 



Lower margin of furrow of chelicerce with but two teeth. Labium 

 longer than wide, the basal excavation longer than is common ; front 

 margin substraight, or but slightly convex. Legs with the tibia + patella 

 of the fourth pair longer than the cephalothorax; the corresponding 

 joints of the first pair slightly shorter than the cephalothorax; anterior
