with long pink hairs. Abdomen pale ochre-yellow, almost naked, 

 clothed with fine short scattered hairs. Sternum pale testaceous ; 

 labium, coxae of legs and pedipalp, and upperside of legs darker ; 

 underside of legs paler testaceous. 



Carapace 8 mm. long ; 7 mm. broad ; 3 mm. wide at base. 

 Cephalic area very prominent and raised above the thoracic area ; 

 broad in front, narrowed and compressed behind, with a deep 

 impression on either side. Thoracic area bilobate behind, with a 

 deep impression on either side towards basal angles. Anterior 

 row of eyes slightly procurved ; centrals very small, two diameters 

 apart, six from laterals. Lateral anteriors within one transverse 

 diameter from margin of clypeus. Anterior row very slightly 

 wider than posterior. Central posteriors reniform, their axis 

 usually distinctly longer than diameter of posterior laterals ; rather 

 over one transverse diameter from the latter. (These proportions 

 are variable.) Base of mandibles with a rdteau in front, furnished 

 with numerous spicules. Faiig-groove armed with 4 stout teeth 

 on the outer margin, 6 on the inner, with intermediate cusps 

 between the two rows. 



Sternum, including labial plate, 7 mm. long, 4 mm. broad. Five 

 pairs of sigilla clearly marked ; 1st pair at base of labium, on 

 either side ; 2nd pair at base of labium behind, coalesced to form 

 a deep longitudinal furrow ; 3rd, 4th, and 5th longitudinal ; 

 central convergent, far remote from margin, coalescing to form 

 a deep central depression. Spinners four, posterior pair three- 

 jointed ; basal joint longest, terminal very sliort, tuberculate. 

 Labial plate not distinct from rest of sternum ; longer than broad, 

 its apex studded with a few minute cuspules. Coxa of pedipalp 

 as long as broad; its anterior distal angle produced; anterior basal 

 angle and whole of inner margin of disc studded with minute 

 cuspules. Patella armed on outside with 2 small distal spines, on 

 inner side with 5 or 6 long spines ; tibia and tarsus armed on. 

 both sides with numerous longer and shorter spines. 



Legs. Tarsus and protarsi i. and ii. armed on outer sides with 

 numerous spines. Tibia i. with one or two minute spines or 

 none on inner side ; outer side with a few. Tibia ii. with none 

 on inner side ; with numerous spinules on outer side. Patella 

 and tibia iii. with numerous spines on either side and along the 

 anterior margin at apex. Protarsus and tarsus iii. with numerous 

 spinules on either side. Patella iv. with numerous spines on 

 outer side, and 5 or 6 along apical outer margin ; protarsus iv. 

 with one or two at apex ; tarsus iv. with several on either side. 



Measurements in millimetres. — Carapace 8 long, 7 broad. Total 

 length, including base of mandibles, 25. Sternum, including labial 

 plate, 7 long, 4 broad. Pedipalp 15 long. Legs i. 16, ii. 16, 

 iii. 16'5, iv. 20 long : all from base of coxa. 



Two specimens ( 5 ) were taken from the sand on the campo 

 close to Santarem, while digging out a tube of Santaremia pocooki ; 

 and a little later a colony of about twenty was found on the same 

 campo, nearer the forest. These, all females, had constructed
