of legs beneath black or brownish black, subdensely clot lied with 

 blackish hair, the longer ones of which appear lighter distally. Legs 

 yellow or light brown, of usually a distinctly greenish tinge, becoming 

 darker with age; femora paler beneath; in adults in most cases entirely 

 without any dark annuli or other markings or with some narrow, 

 mostly faint darker-cross marks on the femora above (for young speci- 

 mens vid. note infra.) ; clothed wdth short appressed fine hairs of yellow, 

 and longer black hairs; scopula3 black. Abdomen dark brown; above 

 with a black median basal mark which widens from its base to its middle, 

 where it projects on each side in a pointed angle or line, and then 

 narrow^s to its apex which bifurcates, sending a narrow pointed line 

 caudo-laterally on each side, the margins of the stripe deeper colored 

 than central portion; a short distance back of the apex of the l^asal 

 mark is a black angular or chevron-shaped transverse mark ; and following 

 this behind over the posterior part of dorsum is a series of light brown 

 or yellow chevron-lines, each of which terminates at each of its ends in 

 a circular spot of the same color; each light chevron-line bordered in 

 front by a black line of similar form; lateral part of dorsum mixed 

 black and brown, a large black spot over each antero-lateral angle* 

 sides mostly dark brown with many small spots of yellow and of black; 

 lower parts of sides and the venter brown to yelloAv with numerous 

 small dots of black, less commonly immaculate, and at other times 

 almost entirely black; abdomen densely clothed with black and yellow 

 hair intermixed, the one predominating on the dark markings, the other 

 on the light. Spinnerets bro^vn. Epigynum dark reddish brown. 



Face rather low, its sides convex and strongly oblique; pare cephalica 

 not elevated above pars thoracica, the dorsal line but little sloping 

 from the third eye row to the posterior declivity, not depressed at 

 middle. 



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

 anterior median eyes distinctly larger than the lateral, less than their 

 radius apart, about an equal distance from the lateral eyes; anterior 

 lateral eyes separated from the front margin of the clypeus by once and 

 a third their diameter, or little more, the same distance from eyes of 

 second row; eyes of second row three-fourths their diameter apart; 

 cephalothorax 5.5 to 6 times as long as the quadrangle of posterior eyes. 

 Chelicerce with margins of fiu'row armed as usual, the first tooth of the 

 inferior margin often with its lower part concealed by a marginal keel 

 extending from base of claw. Labium longer than wide (9.5 :S.75); 

 basal excavations one-third the total length; sides rounded below, 

 above nearly straight, converging to the front margin which is widely
