shorter than femur with patella of the second; metatarsus of the 

 first long, slightly bent; tarsus of the first with fringe of hairs. The 

 tibial and metatarsal spines are long and slender, and are arranged 

 in inferior rows. 



Coloration (dry): Upper surface of cephalothorax light brown with a 

 dark line around the lower margin; eye-region and ©lypeus pale, 

 covered with white and red hairs. Upper surface of abdomen 

 blackish, with a white central longitudinal band extending through 

 two-thirds of its length; this band suddenly contracts a little beliind 

 its middle point, its posterior end being thus made narrower than its 

 anterior portion. The posterior end of the venter is blackish, the 

 color being continuous with that of the upper surface, and extending 

 forward in a gradually narrowing band, to about the middle; on 

 either side of this band, and at the anterior end, the venter is white. 

 Legs and palpi pale with dark bands and black tips, the first and 

 second pairs of legs being darker than the third and fourth; tarsus 

 of the first black with a fringe of black hair. Other parts all pale. 



Habitat: Mexico.

Cephalic and thoracic parts equally long. Quadrangle of eyes one-third 

 wider than long. Eyes of the first row twice as large as those of 

 second. Clypeus nearly one-half as high as anterior eyes. Falces 

 weak, nearly vertical, about as long as face; fang short. Maxillss 

 rounded and a very little enlarged at their extremities, excavated on 

 their inner sides for the labium. Labium a very little longer than 

 w^ide, more than one-half as long as maxillae, widest in the middle, 

 blunt at tip. Legs stouter than is usual in this genus, 1, 2, 3, 4, Fe- 

 mur of the first but little longer than femur of the second. Fringes 

 of hair on upper and under sides of tibia of the first, on under side 

 of tibia of the second, and on outer distal half of femur of palpus. 



Coloration (dry): Upper surface of cephalothorax pale brown with a 

 dark rim around the lower margin. Eye region covered with bright 

 yellowish red hairs, which surround the anterior eyes. Clypeus fight 

 brown, with lower margin black. Upper surface of abdomen dark 

 drab, with a wide, pale central band extending through half of its
