mesad of each ocellus and curving caudoectad and ventrad on the 

 caudal surface of tubercle, (Plate 6, fig. 1). 



First joint of mandible nearly smooth, a little roughened over dorsal 

 surface; hairs above few and straight, more on mesal surface. Second 

 joint also smooth except for a light dorsal roughening; with a few 

 longer hairs at distal end above and laterally with a more numerous 

 patch on mesal side distad, (Plate 6, fig. 2, 3). 



Pedipalps moderately long. Femur ventrally along ectal and 

 similarly along mesal side with a row of acute teeth ; also with a patch 

 of teeth above and laterally at distal end. Dorsoectal and dorso- 

 mesal surfaces of patella with fine teeth which are largest and most 

 numerous on the dorsomesal process, a narrow dorsal stripe free from 

 teeth or nearly so. Tibia with teeth ventrally and especially laterally 

 and dorsolaterally, a middorsal stripe free from teeth. The long 

 slender tarsus free irom teeth but with numerous short fine and a few 

 coarser short hairs. 



Legs with numerous fine teeth which become smaller and less con- 

 spicuous in going distad. 



Length of body 3.8 mm. Length of palp cir. 4.5 mm.; of leg I, 

 32.5 mm.; of leg II, cir. 80 mm.; of leg III, 41 mm.; of leg IV, 5L5 mm. 



Localities.— Paltaybamba, 5,000 feet, August 27. (Type, M. C. Z. 

 136). Santa Ana, 3,000 feet, August 3. (Paratype, M. C. Z. 137, 

 one specimen). 



LioPAGUS,^ gen. nov. 



Eye-tubercle weakly longitudinally furrowed; wholly smooth, 

 bearing no teeth or spines or other processes. 



Body essentially smooth. 



Scutum unarmed. 



First joint of mandible at base with the usual ventral process. 



Patella of pedipalp with a moderate inner apophysis. Claw dis- 

 tinctly pectinate. 



A one pointed process on dorsal margin of distal end of all coxae. 

 Legs thin; moderately long. Femur II with two false sutures; III 

 with none and IV with one. 



Genotype. — Liopagus simplex, sp. nov. 



Related to Prionostemma Pocock in the presence of false sutures 

 only on second and fourth femora. From that genus it is most e'asily 

 distinguished in having on femur II only two sutures or joints instead 

 of the three uniformly present in Prionostemma. 



I Xcios. smooth, Trdyos, a peak.
