 second row, its eyes adequal and its middle eyes decidedly higher, 

 shorter than the second row. Eyes of second row much the largest, 

 less than their diameter apart. Third row widest, its eyes nearly 

 twice their diameter behind the second row. Dorsal eye area almost 

 one-quarter the length of the cephalothorax. Quadrilateral of the 

 posterior eyes broader than long. Third row scarcely wider than the 

 second. 



Form. — Cephalothorax in front about one-half its greatest trans- 

 vei'se diameter, highest at the posterior ej'es, sides of the head steep. 

 Chelicera with three pairs of teeth, longer than the clypeus wide, their 

 length barely 1.75 times the height of the head in front. Sternum 

 longer than broad. Labium longer than wide, concave apically, about

Color (in alcohol). — CephoIotJwrax brown or blackish, white between 

 the eyes of the second row and a white line below each of these eyes. 

 A median buff or reddish-brown band, almost as broad as the eye area, 

 extends from the eye region along the whole length of the cephalothorax 

 and is slightly constricted anterior to the dorsal groove. There is a 

 narrow, undulating, buff submarginal band, and the extreme margin is 

 black. Sternum brown or black, darker than the coxce. Abdomen with- 

 out a median band, a large whitish or pale j-ellow spot covers almost 

 the anterior third of the dorsum, and behind it on the dorsum are 

 5-6 pairs of smaller spots of the same color, the posterior ones appear- 

 ing as transverse stripes due to the confluence of their component 

 spots; each row of these light markings is bordered laterally by a broad 

 black stripe. Sides mottJed with black or gray. Venter black in one 

 specimen, mottled black and j^ellowish in the other. Epigynum yellow. 

 Chelicera deep reddish-black, labium the same color with yellowish tip,
