as high as middle eyes, vertical; falces extending to inner edges of 

 lateral eyes, as long as face, vertical, divergent; fang short, rather 

 stout. Maxillas parallel, enlarged and truncated at extremity, with 

 l^rojection on outer corner. Labium scarcely one-half as long as 

 maxillae, but little longer than wide, contracted at tip. Sternum less 

 than one-half longer than wide, truncated in fi-ont, narrow behind. 

 Anterior coxge separated by more than width of labium. Legs, first 

 and second stoutest, with femoral joints enlarged and compressed. 

 Femoral, tibial and metatarsal spines on the four pairs; femoral 

 spines weak; tibial and metatarsal spines of the first and second in two 

 inferior rows, on tha third and fourth very weak; on the metatarsi 

 irregularly on the body of the articulation as well as in terminal 

 circles. 



Coloration: Cephalothorax dark reddish brown with a white band on each 

 upper side, and, on the face, two snowy white bands which begin on 

 each side between the middle and lateral eye and extend obliquely 

 downward and backward to the cephahc margin. Parallel with 

 these are two equally wide and wliite bands which cover the anterior 

 faces of the falces. These bands make the appearance of the spider 

 from in front very striking and characteristic. Abdomen reddish 

 brown in the middle, with a longitudinal black band on each side; 

 on each of these bands, near the apex, is a white dot, and below, the 

 sides and base are encircled by a white band. Palpus brown with a 

 ring of white hairs at the distal end of the femur. Mouthparts, ster-
