Cephalothorax high and convex, a little dilated behind dorsal eyes, sides 

 nearly vertical in front, and rounded behind, more widely in $ than 

 in $ ; cephalic part inclined; thoracic part slanting a little from dor- 

 sal eyes, and dropping abruptly near posterior border. Ocular area 

 occupying two-fifths of cephalothorax, one-fourth wider than long, 

 slightly wider in front than behind. Anterior eyes on a projecting 

 ridge, all sub-touchuig, in a slightly ciuwed row; lateral about one-half 

 as large as middle eyes; eyes of second row half way between lateral 

 and dorsal eyes; dorsal a little smaller than lateral eyes, further from 

 each other than from lateral borders, forming a row narrower than 

 the cephalothorax at that place. Clypeus retreating, one-third as high 

 as middle eyes. Falces but little wider than the two middle eyes, 

 about as long as face, inclined backward, parallel; fang extremely 

 weak. MaxiUse parallel, but little enlarged at extremity, (S) almost 

 truncated, ( $ ) blunt, inner edge vertical. Labium one-half as long- 

 as maxillte, narrow and hollowed at base, enlarged in middle, con- 

 tracted at tip ( 5 ) nearly twice as long as wide, (?) but little longer 

 than wide. Sternum one-half longer than wide, truncated in front, 

 narrow and rounded behind. Anterior cox8e separated by more than 

 the width of the labium. Legs all slender; femoral, tibial and meta- 

 tarsal spines on aU the legs, and patellery sjiines on the third and the 

 fourth; metatarsi of the fourth spined throughout then- length. Fe- 

 moral joints of the first and second not enlarged, but compressed, es- 

 pecially in $ . 



Coloration: Cephalothorax dark brown; eye region black; centi-al thoracic 

 region covered with gray and rufus hairs; lower margin black; red- 

 dish rings around anterior eyes. Abdomen dark brown or black; 

 a white central band arises at base, and enlarging and then agaia 

 narrowing, reaches the central point of the dorsum; posterior to this 

 two short, obhque, white bands form a chevron whose apex, pointing 

 forward, touches the extremity of the central band; near the apex are 

 several small white chevrons; there is a white band on each side. 

 The white dorsal markings in the $ are sometimes broken up as in 

 figure 50; usually they resemble those of the S . Clypeus, falces, 

 mouthparts, sternum and venter brown, glabrous. Palpi and legs
