tibia of 4th also covered in front with a thick coating of silky red 

 hairs. Claws of 1st, 2nd, and 3rd legs armed with a single long 

 tooth and one short one. Claws of 4th leg unarmed. 



Measurements in millimetres. Total length 30 ; length of carapace 

 18 ; width of posterior line of eyes 4-5 ; length of palp 16-5, of 

 1st leg 22, of 2nd 20-5, of 3rd 21, of 4th 27 ; length of 4th pro- 

 tarsus 6, of 1st protarsus 4-7. 



Loc. Bloemfontein in the Orange Free State. 



A single female example with its trap-door nest was received 

 from Dr. Exton. 



The door of this nest is thick with bevelled edge, being 37 mm, 

 (almost Ik inches) from side to side, and 30 mm. {1\ inch) from 

 hinge to the opposite border ; the bore of the tube one inch from 

 the aperture is about 23 mm. {\\ of an inch). 



This species and the Natal form identified as riifidens, Auss., 

 may be determined as follows : — 



a. Width of the ocular area (posterior line of eyes) almost 

 equal to the protarsus of 1st leg, and about three-quarters 

 the length of the 4th protarsus ; length of carapace 

 almost equal to length of patella, tibia, and protarsus of 

 1st leg, greater than the same segments of the 2nd ; 

 protarsi of 3rd and 4th legs with apical tuft of spinules 



beneath - oculatus, sp. n. 



(Bloemfontein). 



h. Width of ocular area (posterior line of eyes) equal to only 

 about two-thirds of the protarsus or tibia of the 1st leg, 

 and less than half the 4th protarsus ; length of carapace 

 just excelling the length of the patella, tibia, and half 

 the protarsus of the 1st leg, less than these tliree seg- 

 ments of the 2nd leg ; protarsi of 3rd and 4th legs with- 

 out inferior apical tuft of spinules rufidens, Auss. 



(Natal).

In addition to the two African species recorded below, this 

 genus contains two described by Simon from S. India and Ceylon.

^ Of the IdiopecB, M. Simon saj's that apart from the eye-formula the group 

 presents all the characters of the Pachylomerea ; this, however, is hardly in ac- 

 cordance with fact, since in Pacht/lomerus there is a single pair of submedian 

 sternal sigilla corresponding to the 3rd pair of legs, those representing the Ist 

 and 2nd pair being evanescent, whereas in the genera of Idiopece it is the 

 latter sigUla that persist, the posterior pair having disappeared.
