rather concave near inner tip ; tibia about as long as femur, rather long 

 pedicellate, much swollen on inner side and then almost concave, as broad as 

 the femur ; claw much longer than cephalothorax and mandibles together, the 

 hand nearly as long as tibia, extremely broad, about two and a half times as 

 broad as tibia, truncate at base, tapering to the fingers, which are rather 

 slender, curved and nearly as long as the hand ; clavate hairs on trochanter, 

 femur and inner surfaces of tibia and hand, also clavate hairs on upper 

 surface of legs. Stylet of mandibles short and simple. Dorsal scutae very 

 narrow, with about eight hairs behind. 



Length 4 mm. 



From Tucson, Arizona, and Lower California, Mexico. 



5. Chelanops calidus, new species. 



Cephalothorax yellow-brown, palpi uniform pale yellowish brown, dorsal 

 scutae brownish. Cephalothorax finely granulate, with few clavate hairs ; 

 stylet of mandible slender and simple. Palpi rather short ; trochanter gibbose 

 above and also behind ; femur hardly as long as width of cephalothorax, sides 

 nearly parallel, rather broadest near base ; tibia nearly as long as femur, 

 evenly convex on the inner side, plainly broader than the femur; claw longer 

 than cephalothorax plus mandibles, hand rather heavy, about twice as broad 

 as the tibia, broadest at base, tapering to the fingers, which are as long as 

 hand, and rather large. A few nearly clavate hairs on the trochanter, other 

 hairs simple, long and variable in length. Dorsal scutas short, with about five 

 simple bristles on posterior edge ; long bristles on the last segment. 

 Length, 5 2.5 mm. ; ^ 2 mm. 

 From Sonera, and Lower California, Mexico. 



5. Chelanops confraternus, new species. 



Closely related to Chelanops nitidimanus Ell. ; the proportions of parrs 

 similar to that species. The femur of palpus fully two and one half times as 

 long as broad ; the fingers as long as hand ; the hand as described for C. 

 nitidimanus, the hairs barely clavate. The three hairs on the posterior edge 

 of each dorsal scutum are strongly clavate, and very short ; the cephalothorax 

 is granulate behind, but nearly smooth in front. The cephalothorax and palpi 

 dark red-brown, the fingers paler, the cephalothorax has a long white spot each 

 side behind as in C. nitidimanus, and the first abdominal segment also has 

 the same spots, while the fourth to ninth segments inclusive have at their 

 outer tips a distinct white spot, making five white spots along each side at the 

 middle of the abdomen. 



Length 2 mm. 



From Poco Grande, Brazil. 



7. Chelanops garcianus, new species. 



Color pale yellowish brown. The cephalothorax with groove behind the 

 middle, surface finely and evenly granulate ; stylet of mandibles simple, not 

 very long, point outcurved ; palpi of moderate length, the trochanter with two-
